Substitute Part Grouping Explanation

Substitution eligibility for the RER60FR100MCSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 mOhms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to +250°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Package classification: Axial, Box
• Military qualification: MIL-PRF-39009 series

The RER60FR100RC02 meets all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Vishay Dale within the RER60 military series and share identical dimensional specifications (0.600" L × 0.646" W, 15.24mm × 16.41mm).

Parameter Comparison

Engineering Selection Recommendations

Both the RER60FR100MCSL and RER60FR100RC02 are active production components qualified to MIL-PRF-39009 military standards. Selection between these parts should be based on the following factors:

RER60FR100MCSL is appropriate for applications where standard military failure rate classification (M, 1%) is acceptable and current inventory availability (697 units) supports project timelines.

RER60FR100RC02 is appropriate for high-reliability applications requiring lower failure rate performance (R, 0.01%) and where REACH compliance status is a procurement requirement. This part carries enhanced reliability certification and is available with 793 units in stock.

Both parts are RoHS non-compliant and carry identical export classification (EAR99). Selection does not require design modification or re-qualification when substituting between these two part numbers within the same application.

Frequently Asked Questions (FAQ)

Q: Can RER60FR100RC02 be used as a direct replacement for RER60FR100MCSL?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The RER60FR100RC02 features a lower failure rate classification (R vs. M) and REACH compliance status, making it suitable for direct substitution without circuit redesign.

Q: What is the difference in failure rate between these parts?

A: The RER60FR100MCSL carries a failure rate of M (1%), while the RER60FR100RC02 carries a failure rate of R (0.01%). The R classification indicates higher reliability performance and is appropriate for mission-critical applications.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical dimensions: 0.600" L × 0.646" W (15.24mm × 16.41mm) with a maximum seated height of 0.335" (8.51mm). Mounting configuration, lead style, and package type are identical.

Q: What compliance certifications apply to both parts?

A: Both parts are qualified to MIL-PRF-39009 military standard, carry EAR99 export classification, and are assigned HTSUS code 8533.21.0080. Both are RoHS non-compliant. The RER60FR100RC02 additionally carries REACH compliance status.

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

A: Yes. No PCB layout modifications, thermal management adjustments, or electrical parameter re-evaluation are required when substituting between these part numbers. Both maintain identical electrical performance across the full operating temperature range of -55°C to +250°C.
