Engineering Selection Recommendations

All identified substitute parts are Active in product status and RoHS3 compliant, meeting current regulatory requirements. The following considerations apply to part selection:

AC0805FR-078K25L (YAGEO): Carries AEC-Q200 automotive qualification with moisture-resistant features. Seated height of 0.024" (0.60mm) is lower than the main part.

CRCW08058K25FKEA (Vishay Dale): Carries AEC-Q200 automotive qualification. Offers the lowest seated height at 0.020" (0.50mm), suitable for space-constrained applications.

ERJ-6ENF8251V (Panasonic Electronic Components): Carries AEC-Q200 automotive qualification. Seated height of 0.028" (0.70mm) is the highest among substitutes.

RC0805FR-078K25L (YAGEO): Moisture-resistant thick film composition without automotive qualification. Seated height of 0.024" (0.60mm).

RMCF0805FT8K25 (Stackpole Electronics Inc): Carries AEC-Q200 automotive qualification. Seated height of 0.026" (0.65mm) closely matches the main part.

All substitute parts maintain identical electrical specifications and package dimensions, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the RCS2012F8251CS?

A: Yes. All substitute parts match the critical electrical specifications (8.25 kOhms ±1%, 0.125W), package type (0805/2012 Metric), temperature range (-55°C to 155°C), and compliance requirements (RoHS3, MSL 1). Direct substitution is supported without circuit design modification.

Q: What is the significance of the seated height differences among substitute parts?

A: Seated height variations range from 0.020" to 0.028" (0.50mm to 0.70mm). These differences may impact PCB clearance in space-constrained designs. The main part RCS2012F8251CS has a seated height of 0.026" (0.66mm). Verify clearance requirements for your specific application before selecting a substitute with significantly different height.
