Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RER45F10R0PCSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 250°C
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Housing type: Aluminum
• Physical dimensions: 0.750" L x 0.800" W (19.05mm x 20.32mm)
• Height - Seated (Max): 0.405" (10.29mm)
• Series compliance: Military, MIL-PRF-39009, RER45

The RER45F10R0RC02 meets all these criteria and is classified as a parametric equivalent. Differences in failure rate and REACH certification status do not affect functional or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both RER45F10R0PCSL and RER45F10R0RC02 are active products manufactured by Vishay Dale within the Military MIL-PRF-39009 RER45 series. Both components are RoHS non-compliant and carry identical ECCN and HTSUS classifications. The RER45F10R0RC02 features a lower failure rate specification (R at 0.01% versus P at 0.1%), which may be advantageous for applications with extended operational life requirements. REACH certification information is available upon request for the RER45F10R0RC02. Selection between these parts should be based on inventory availability, delivery schedule requirements, and specific failure rate performance criteria for the application.
