Key Parameters

Substitute Part Grouping Explanation

Substitution of the CR2512-JW-621ELF is determined by strict equivalence across the following parameters: resistance value (620 Ohms), tolerance (±5%), power rating (1W), package type (2512 / 6432 Metric), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts meet these core electrical and mechanical requirements. Dimensional variations within the 2512 package specification are permissible. RoHS3 compliance and MSL 1 rating are maintained across all alternatives. Substitute parts may include additional certifications such as AEC-Q200 automotive qualification, which does not restrict their use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The CR2512-JW-621ELF (Bourns Inc.) and CRCW2512620RJNEG (Vishay Dale) are both active production parts suitable for new designs. The RMCF2512JT620R (Stackpole Electronics Inc) is also active and available. The ERJ-1TYJ621U (Panasonic Electronic Components) carries a "Not For New Designs" status and should be used only when existing inventory or legacy design requirements necessitate its selection. All three active alternatives provide equivalent electrical performance and meet identical compliance requirements. Selection among active parts may be based on availability, lead time, and supplier preference.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512620RJNEG replace CR2512-JW-621ELF directly? A: Yes. Both parts meet identical electrical specifications (620 Ω ±5%, 1W, ±200ppm/°C, -55°C ~ 155°C) and are packaged in the 2512 (6432 Metric) form factor. Dimensional tolerances within the 2512 specification are equivalent.

Q: What is the difference between the active and "Not For New Designs" parts? A: The ERJ-1TYJ621U is designated "Not For New Designs" by Panasonic, indicating it is in mature or end-of-life status. For new circuit designs, select from CR2512-JW-621ELF, CRCW2512620RJNEG, or RMCF2512JT620R.

Q: Do the AEC-Q200 certifications on some substitute parts affect compatibility? A: No. AEC-Q200 is an automotive qualification that indicates additional testing and reliability screening. Parts with AEC-Q200 certification are fully compatible with non-automotive applications and do not impose restrictions on use.

Q: Are there dimensional differences between substitute parts? A: Minor dimensional variations exist within the 2512 package specification. All parts maintain the same footprint and are mechanically interchangeable on standard PCB layouts. Maximum seated heights range from 0.028" to 0.030", all within acceptable assembly tolerances.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the original design was qualified for the CR2512-JW-621ELF. All substitute parts meet or exceed the same electrical and environmental specifications. PCB layout and assembly processes require no modification.
