Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RMC1/10K63R4FTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 63.4 Ohms (exact)
• Tolerance: ±1% (exact)
• Power Rating: 0.125W / 1/8W (exact)
• Package / Case: 0805 (2012 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature Coefficient: ±100ppm/°C (exact)
• Operating Temperature Range: -55°C ~ 155°C (exact)

Acceptable Variation Parameters:

• Manufacturer: Different manufacturers permitted
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats acceptable
• Height - Seated (Max): Variation within 0.024" to 0.028" (0.60mm to 0.70mm) acceptable for PCB assembly
• Product Status: Active or Discontinued at DiGi Electronics both acceptable
• Certifications: Additional certifications (AEC-Q200, Moisture Resistant) do not disqualify substitution

All four substitute parts meet these criteria and are electrically and mechanically interchangeable with the main part number RMC1/10K63R4FTP.

Parameter Comparison

Engineering Selection Recommendations

ERJ-6ENF63R4V (Panasonic Electronic Components)

This substitute carries Automotive AEC-Q200 certification, indicating qualification for automotive applications with enhanced reliability requirements. Product status is Active with 77,369 pieces in inventory, providing strong supply availability. Height dimension of 0.028" (0.70mm) is within acceptable tolerance for standard PCB assembly processes. ROHS3 compliance is confirmed. Selection is appropriate for applications requiring automotive-grade components or where enhanced reliability documentation is necessary.

MCR10ERTF63R4 (Rohm Semiconductor)

This substitute is classified as Discontinued at DiGi Electronics, indicating limited future availability through standard distribution channels. Current inventory of 954 pieces is available. Height dimension of 0.026" (0.65mm) matches the main part specification exactly. ROHS3 compliance is confirmed. Selection should be limited to applications where existing stock is sufficient and long-term supply is not a requirement.

RC0805FR-0763R4L (YAGEO)

This substitute features Moisture Resistant composition, providing enhanced protection in humid environments. Product status is Active with 30,302 pieces in inventory. Height dimension of 0.024" (0.60mm) is the lowest among all options, suitable for space-constrained PCB designs. ROHS3 compliance is confirmed. Selection is appropriate for applications in moisture-prone environments or where compact assembly height is beneficial.

RMCF0805FT63R4 (Stackpole Electronics Inc)

This substitute carries Automotive AEC-Q200 certification for automotive applications. Product status is Active with 1,030 pieces in inventory. Height dimension of 0.026" (0.65mm) matches the main part specification exactly. ROHS3 compliance is confirmed. Selection is appropriate for automotive applications requiring AEC-Q200 qualification with moderate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF63R4V replace RMC1/10K63R4FTP in non-automotive applications?

A: Yes. The ERJ-6ENF63R4V meets all electrical and mechanical parameters required for substitution. Automotive AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. The component is electrically and mechanically equivalent.

Q: What is the significance of the height difference between RC0805FR-0763R4L (0.024") and ERJ-6ENF63R4V (0.028")?

A: Both heights fall within acceptable tolerance for standard 0805 package assembly. The 0.004" (0.10mm) difference is negligible for most PCB designs. Selection between these parts should be based on other factors such as product status, certifications, or supply availability rather than height variation.

Q: Is MCR10ERTF63R4 suitable for new product designs?

A: MCR10ERTF63R4 is classified as Discontinued at DiGi Electronics. While current inventory exists, this part number is not recommended for new product designs requiring long-term component availability. Active alternatives such as ERJ-6ENF63R4V, RC0805FR-0763R4L, or RMCF0805FT63R4 are preferred for designs with extended production lifecycles.

Q: What does Moisture Resistant mean for RC0805FR-0763R4L?

A: Moisture Resistant composition provides enhanced protection against moisture ingress and environmental degradation. This feature is beneficial for applications exposed to high humidity, condensation, or corrosive environments. All substitute parts carry MSL 1 (Unlimited) rating, indicating standard moisture sensitivity handling is sufficient.

Q: Are all substitute parts ROHS3 compliant?

A: ERJ-6ENF63R4V, MCR10ERTF63R4, RC0805FR-0763R4L, and RMCF0805FT63R4 are all confirmed ROHS3 compliant. The main part RMC1/10K63R4FTP does not specify RoHS status in the provided data. If RoHS compliance is a design requirement, any of the four substitute parts satisfy this criterion.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts are mechanically and electrically equivalent within the specified parameters. PCB footprints are identical (0805 / 2012 Metric). Height variations (0.024" to 0.028") are within standard assembly tolerances. Parts can be substituted without PCB redesign or assembly process modification.

Q: Which substitute offers the best supply availability?

A: RC0805FR-0763R4L (YAGEO) offers the highest inventory with 30,302 pieces in stock, followed by ERJ-6ENF63R4V (Panasonic) with 77,369 pieces. Both parts carry Active product status, ensuring continued availability through distribution channels.
