Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance. Selection among these alternatives depends on application-specific requirements:

RMCF0805FT2K87 (Stackpole Electronics Inc): Automotive AEC-Q200 rated variant from the same manufacturer. Suitable for automotive and high-reliability applications requiring AEC-Q200 qualification.

CRCW08052K87FKEA (Vishay Dale): Automotive AEC-Q200 rated option with the lowest seated height (0.020" / 0.50mm), beneficial for space-constrained PCB layouts.

ERJ-6ENF2871V (Panasonic Electronic Components): Automotive AEC-Q200 rated alternative with highest inventory availability and maximum seated height (0.028" / 0.70mm).

RC0805FR-072K87L (YAGEO): Moisture-resistant thick film variant without automotive rating. Suitable for general-purpose and consumer applications with moisture exposure considerations.

Frequently Asked Questions (FAQ)

Q: Can RMCS0805FT2K87 be directly replaced with any of these substitutes?

A: Yes. All substitute parts match the core electrical specifications (2.87 kOhms ±1%, 0.125W), package footprint (0805), and environmental ratings (ROHS3, MSL 1). Direct PCB replacement is possible without circuit modification.

Q: What is the difference between the main part and RMCF0805FT2K87?

A: Both are Stackpole products with identical electrical specifications. RMCF0805FT2K87 carries AEC-Q200 automotive qualification, making it suitable for automotive applications where the main RMCS variant may not be specified.

Q: Are there height differences that affect PCB assembly?

A: Yes. Seated heights vary from 0.020" (CRCW08052K87FKEA) to 0.028" (ERJ-6ENF2871V). In space-constrained designs or high-density layouts, the lower-profile CRCW variant may be preferred. The main part and RC0805FR-072K87L both measure 0.024" (0.60mm).

Q: Which substitute is best for automotive applications?

A: RMCF0805FT2K87, CRCW08052K87FKEA, and ERJ-6ENF2871V all carry AEC-Q200 automotive qualification. Selection depends on manufacturer preference, availability, and specific height requirements.

Q: Is packaging format (Tape & Reel vs. Cut Tape) significant for substitution?

A: Packaging format affects supply chain and handling but does not impact electrical or mechanical compatibility. RMCS0805FT2K87 and RMCF0805FT2K87 are supplied in Tape & Reel format. RC0805FR-072K87L is available in Cut Tape & Digi-Reel format. All others use Tape & Reel.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not impose specific manufacturer or certification requirements. All parts meet the same electrical performance, temperature range, and compliance standards. Verify component sourcing policies and qualification requirements before implementation.
