Substitute Part Grouping Explanation

Substitution eligibility for the RER70F1000PCSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 20W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 250°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Physical dimensions: 1.062" L x 1.080" W (26.97mm x 27.43mm)
• Height seated (max): 0.561" (14.25mm)
• Military qualification: MIL-PRF-39009 RER70 series

The RER70F1000RC02 meets all substitution criteria as a parametric equivalent within the same military-qualified product line.

Parameter Comparison

Engineering Selection Recommendations

Both the RER70F1000PCSL and RER70F1000RC02 are active production components manufactured by Vishay Dale under MIL-PRF-39009 military specifications. Selection between these parts should be based on the following factors:

The RER70F1000RC02 offers a lower failure rate classification (R at 0.01% versus P at 0.1%), which may be advantageous for applications with stringent reliability requirements. Both parts carry identical RoHS non-compliance status and EAR99 export classification. Moisture sensitivity level 1 (unlimited) applies to both components, indicating no moisture-related handling restrictions during storage or assembly.

Inventory availability differs between the two parts, with RER70F1000RC02 currently stocked at 863 units compared to 676 units for RER70F1000PCSL. Selection may be influenced by lead time requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can RER70F1000RC02 be used as a direct replacement for RER70F1000PCSL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (100 Ohms ±1%, 20W), temperature performance (±20ppm/°C, -55°C to 250°C), and mechanical configuration (aluminum housing, flanged mounting, solder lugs). Physical dimensions and package types are identical.

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

A: RER70F1000PCSL is rated at failure rate P (0.1%), while RER70F1000RC02 is rated at failure rate R (0.01%). The lower failure rate of RER70F1000RC02 may be relevant for high-reliability applications.

Q: Are there any compliance or certification differences?

A: Both parts share identical compliance status: RoHS non-compliant, EAR99 export classification, and HTSUS code 8533.21.0080. Both are qualified to MIL-PRF-39009 military specifications within the RER70 series.

Q: Do these parts require special handling or storage considerations?

A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related restrictions for storage or assembly processes.

Q: Are the physical dimensions and mounting configurations identical?

A: Yes. Both parts have identical dimensions (1.062" L x 1.080" W, 26.97mm x 27.43mm) and seated height (0.561" maximum, 14.25mm). Mounting features, lead style, and package configuration are identical.
