Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

Resistance value: 56.2 Ohms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Moisture sensitivity level: MSL 1

Acceptable Variations:

Height seated (maximum): Substitute parts may have different maximum heights (0.024" to 0.028") provided they remain within 0805 package specifications
Manufacturer-specific features: Automotive AEC-Q200 certification or moisture resistance features are additional qualifications that do not disqualify substitution

All identified substitute parts meet these criteria and are classified as Active products with full inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF56R2V replace RMC1/10K56R2FTP in non-automotive applications?

A: Yes. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. All electrical and mechanical parameters are equivalent.

Q: What is the significance of the height difference between RC0805FR-0756R2L (0.024") and RMC1/10K56R2FTP (0.026")?

A: Both heights fall within 0805 package specifications. The 0.002" difference does not affect PCB assembly compatibility or electrical performance. Verify clearance in applications with height-constrained layouts.

Q: Are all substitute parts ROHS3 compliant?

A: RC0805FR-0756R2L and RMCF0805FT56R2 are explicitly ROHS3 compliant. RMC1/10K56R2FTP and ERJ-6ENF56R2V do not list ROHS3 status in provided specifications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across -55°C to 155°C with identical ±100ppm/°C temperature coefficient. No derating is required across the specified temperature range.

Q: Which substitute offers the best inventory availability?

A: RC0805FR-0756R2L (YAGEO) has the highest stock level at 954,563 pieces, followed by ERJ-6ENF56R2V (Panasonic) at 79,680 pieces.

Q: Are moisture-resistant features necessary for standard applications?

A: Moisture resistance is an optional feature. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Moisture-resistant composition in RC0805FR-0756R2L provides additional environmental protection but is not required for standard use.
