Substitute Part Grouping Explanation

Substitution eligibility for the RER75F2R00MCSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 Ohms
• Tolerance: ±1%
• Power rating: 30W
• Composition: Wirewound
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 250°C
• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box
• Series compliance: Military, MIL-PRF-39009, RER75

The RER75F2R00RC02 meets all substitution criteria as a parametric equivalent within the same product series and manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

Both the RER75F2R00MCSL and RER75F2R00RC02 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Compliance documentation: RER75F2R00RC02 includes REACH status information available upon request

Both parts comply with military specifications MIL-PRF-39009 and are suitable for applications requiring high-reliability wirewound resistors in extended temperature environments.

Frequently Asked Questions (FAQ)

Q: Can RER75F2R00RC02 be used as a direct replacement for RER75F2R00MCSL?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and mounting characteristics. They are interchangeable in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are failure rate specification (M versus R) and REACH compliance documentation availability. Electrical and mechanical performance are identical.

Q: Are there any packaging or mounting differences?

A: No. Both parts use identical Axial, Box packaging with solder lugs and flange mounting features. Physical dimensions are 1.968" L x 1.140" W with a maximum seated height of 0.625".

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

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Are these parts RoHS compliant?

A: No. Both RER75F2R00MCSL and RER75F2R00RC02 are RoHS non-compliant, consistent with military-grade wirewound resistor specifications.
