NX2016SA 25MHz SMD Crystal — Specs, Price & Stock Update
NX2016SA 25MHz SMD Crystal — Specs, Price & Stock Update
Sampled distributor listings and inventory checks show the NX2016SA 25MHz SMD crystal priced from roughly $0.35 to over $1 per unit depending on quantity and distributor.
This brief market snapshot frames the article: summarize technical specs, current price and stock signals, buying considerations, and practical next steps for engineers and procurement teams.
The goal is to give concise, testable guidance for qualifying the part in production and for sourcing decisions. The intro uses the SKU NX2016SA-25.000M-STD-CZS-1 where helpful, and highlights the key procurement variable—price—so teams can quickly prioritize sampling, cross-qualification, and lead-time checks before committing to larger buys.
1 — Product overview & key specifications
| Parameter | Standard Specification |
|---|---|
| Package Size | 1.6 × 1.2 mm (2016) |
| Nominal Frequency | 25.000 MHz |
| Load Capacitance (CL) | Typical ~8 pF |
| ESR | Low ESR optimized for MCUs |
1.1 Mechanical & package details
The NX2016SA series ships as an SMD quartz resonator in a 1.6 × 1.2 mm rectangular package with standard pad layout for reflow soldering. Recommended PCB footprint follows typical 2016 crystal land patterns with two pads and thermal relief; maintain typical solder fillet clearances and avoid routing beneath the device to limit stress. Observe manufacturer tolerances on case height and keep handling to standard SMD SMT practice.
1.2 Electrical specs & performance parameters
This family lists a nominal frequency of 25 MHz with typical load capacitance near 8 pF, low drive level (single-digit μW to tens of μW), and ESR values suitable for common microcontroller oscillator circuits. Frequency tolerance and aging should be confirmed on the datasheet; operating temperature ranges commonly span commercial to industrial grades. Always cross-check the datasheet for exact ESR, CL, and drive-level limits for your oscillator topology.
2 — Detailed datasheet checklist & model codes
2.1 Interpreting ordering codes and spec suffixes
Ordering codes encode frequency tolerance, packing, and spec suffixes that affect procurement: tolerance (ppm), package code, and packing reel or tape. For BOM control, capture spec number, frequency, tolerance, load capacitance, and package code. Track alternate suffixes that signal tighter tolerances or different packing; small suffix differences can create costly cross-qualification needs if not caught during ordering.
2.2 Critical test points & measurement verification
Bench verification: measure frequency in the intended oscillator circuit, confirm load capacitance with an LCR meter, and check ESR against datasheet limits. Run frequency-drift tests across operating temperature span and perform short-term aging checks. Pass/fail thresholds: frequency within specified tolerance, ESR no greater than datasheet max, and frequency drift within expected temperature coefficient for the stated grade.
3 — Current price, stock patterns & sourcing signals
3.1 Typical price ranges
Observed unit price bands show low-volume listings near $0.35 and many retail offers above $1. Drivers include minimum order quantity, reel vs. cut-tape, and temperature range specs.
3.2 Stock & lead-time signals
Monitor distributor stock flags. Constrained supply signals include partial stock across codes or long lead times. Consider safety stock if listings show frequent out-of-stock transitions.
4 — Alternatives, cross-references & risk mitigation
4.1 How to identify equivalent alternatives safely
Select alternates by matching frequency, load capacitance, ESR, package, and temperature grade. Compare datasheet line-by-line—pay particular attention to CL, ESR, drive level, and packaging orientation. Red flags include higher ESR, different load capacitance, or altered temperature coefficients; these can change oscillator behavior and require circuit retuning and requalification.
4.2 Short-term mitigation: temporary fixes vs long-term design changes
Short-term options: secure production buys to cover immediate needs, source small sample reels, or qualify a vetted second-source part. Longer-term: adjust oscillator input network to tolerate CL/ESR differences, or switch to a packaged oscillator if form-factor and cost permit. For any mitigation, require a re-test checklist covering frequency accuracy, jitter, and environmental stress tests before acceptance.
5 — Practical procurement checklist & next steps
5.1 Procurement checklist
- Confirm exact ordering code and spec number.
- Request sample batch for electrical testing.
- Verify packaging and moisture-sensitivity level (MSL).
- Confirm lead times, return policy, and traceability.
5.2 Engineering handoff
Engineers should validate PCB footprint and placement tolerances, perform oscillator bench tests on received samples, and document allowed substitutes in the BOM with clear spec boundaries. Annotate the BOM with approved alternate part numbers and the SKU used for initial qualification (for example NX2016SA-25.000M-STD-CZS-1).
Summary
The NX2016SA 25MHz SMD crystal requires careful verification of load capacitance, ESR, tolerance, and packaging before production buys. Price varies widely ($0.35 to $1+), so factor unit cost and lead time into sourcing.
- Verify critical specs: CL, ESR, and tolerance mismatches can alter performance.
- Monitor market signals: Use safety stock when distributor listings show volatility.
- Documentation: Record approved substitutes on the BOM to reduce production risk.
Frequently Asked Questions
What tests confirm the NX2016SA 25MHz SMD crystal meets specs?
Measure the part in the target oscillator circuit to confirm frequency within tolerance, verify load capacitance and ESR with bench instruments, and run temperature sweep tests to observe drift.
How does price influence sourcing strategy for a 25MHz SMD crystal?
Price affects whether to buy in bulk versus sampling; low unit cost at high volume can justify longer lead times, while higher prices for small buys push teams to validate alternates sooner.
Can an alternate crystal be used without redesign for NX2016SA?
Only if the alternate matches frequency, load capacitance, ESR, package, and temperature grade exactly. If a perfect match is unavailable, circuit adjustments may be required.
