Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (1.54 MOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All identified substitutes meet these core electrical and mechanical requirements. Physical dimensions and height variations are within acceptable tolerances for 0805 package specifications. Substitutes are classified as Direct or Similar based on feature alignment and certification scope.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-071M54L (YAGEO) is classified as a Direct Manufacturer substitute. This part maintains identical electrical specifications and package dimensions with a seated height of 0.024" (0.60mm), which is within 0805 package tolerance. ROHS3 compliance and MSL 1 rating confirm environmental and moisture handling equivalence. This substitute is suitable for general-purpose applications requiring standard moisture resistance.

CRCW08051M54FKEA (Vishay Dale) is classified as a Similar substitute with automotive-grade qualification. This part carries AEC-Q200 certification, indicating enhanced reliability for automotive applications. The seated height of 0.020" (0.50mm) represents the lowest profile among substitutes while remaining within 0805 specifications. Selection of this part is appropriate for automotive or high-reliability applications where AEC-Q200 qualification is required or beneficial.

ERJ-6ENF1544V (Panasonic Electronic Components) is classified as a Similar substitute with automotive-grade qualification. This part carries AEC-Q200 certification equivalent to the Vishay Dale option. The seated height of 0.028" (0.70mm) is the highest among substitutes but remains within 0805 package tolerance. Selection of this part is appropriate for automotive or high-reliability applications where Panasonic sourcing is preferred.

All substitutes are Active status products with established supply availability and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071M54L replace RC2012F1544CS in any application?

A: Yes. RC0805FR-071M54L meets all electrical parameters (1.54 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and package specifications (0805, 2.00mm x 1.25mm). The seated height difference (0.024" vs 0.026") is within 0805 package tolerance and does not affect PCB assembly or electrical performance.

Q: What is the difference between CRCW08051M54FKEA and ERJ-6ENF1544V?

A: Both parts are electrically identical and carry AEC-Q200 automotive certification. The primary difference is seated height: CRCW08051M54FKEA measures 0.020" (0.50mm) while ERJ-6ENF1544V measures 0.028" (0.70mm). Both heights are within 0805 specification limits. Selection depends on PCB clearance requirements and manufacturer preference.

Q: Are these substitutes suitable for automotive applications?

A: CRCW08051M54FKEA and ERJ-6ENF1544V carry AEC-Q200 certification and are suitable for automotive applications. RC0805FR-071M54L does not carry AEC-Q200 certification and is suitable for general-purpose applications. Verify application requirements before selection.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All parts including RC2012F1544CS, RC0805FR-071M54L, CRCW08051M54FKEA, and ERJ-6ENF1544V carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Compliance status is identical across all options.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes, from an electrical and compliance standpoint. Physical height variations (0.020" to 0.028") are within 0805 package tolerance and do not affect PCB assembly processes. Verify PCB design clearances if height-sensitive applications exist.
