Parameter Comparison

Engineering Selection Recommendations

RC0805FR-072M05L (YAGEO): Direct equivalent with identical electrical and mechanical specifications. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB assembly. ROHS3 compliant with MSL Level 1 rating. Suitable for general industrial applications requiring moisture-resistant thick film resistors.

CRCW08052M05FKEA (Vishay Dale): Qualified substitute with automotive AEC-Q200 certification. Lowest seated height at 0.020" (0.50mm) provides design flexibility for space-constrained layouts. ROHS3 compliant with MSL Level 1 rating. Recommended for applications requiring automotive-grade reliability and qualification.

ERJ-6ENF2054V (Panasonic Electronic Components): Qualified substitute with automotive AEC-Q200 certification. Seated height of 0.028" (0.70mm) is the highest among listed options. ROHS3 compliant with MSL Level 1 rating. Recommended for automotive and industrial applications requiring AEC-Q200 qualification.

All substitute parts maintain identical electrical performance, operating temperature range, and environmental compliance as the primary part. Selection should be based on application requirements, availability, and specific design constraints such as PCB height limitations.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072M05L replace RC2012F2054CS in all applications?

A: Yes. Both parts share identical electrical specifications (2.05 MOhms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (0805). The seated height difference of 0.002" (0.06mm) is negligible for standard PCB assembly processes.

Q: What is the difference between standard moisture-resistant and automotive AEC-Q200 versions?

A: The RC2012F2054CS and RC0805FR-072M05L feature standard moisture resistance. The CRCW08052M05FKEA and ERJ-6ENF2054V include automotive AEC-Q200 qualification, indicating compliance with automotive reliability and qualification standards. Both feature types maintain identical electrical performance and MSL Level 1 rating.

Q: Are there height restrictions when substituting these parts?

A: Seated heights range from 0.020" to 0.028" (0.50mm to 0.70mm). For most standard PCB designs, this variation is acceptable. Applications with strict height constraints should verify clearance requirements before substitution.

Q: Do all substitute parts have the same RoHS and REACH compliance?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best availability?

A: ERJ-6ENF2054V (Panasonic) shows highest inventory at 29,750 pieces, followed by CRCW08052M05FKEA (Vishay Dale) at 20,934 pieces, and RC0805FR-072M05L (YAGEO) at 10,384 pieces.
