Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RER40F2000RCSL are identified based on strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 5W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C ~ 250°C
• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box
• Failure rate: R (0.01%)
• Military compliance: MIL-PRF-39009

The RER60F2000RC02 meets all these criteria, differing only in series designation (RER60 versus RER40) while maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RER40F2000RCSL and RER60F2000RC02 maintain Active product status and are manufactured by Vishay Dale under MIL-PRF-39009 military specifications. Both components carry identical RoHS non-compliant status and MSL rating of 1 (Unlimited). The RER60F2000RC02 offers 1090 units in stock compared to 898 units for the RER40F2000RCSL, providing improved availability. Selection between these parts should be based on circuit design requirements, PCB layout constraints, and supply chain considerations, as all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the RER60F2000RC02 be used as a direct replacement for the RER40F2000RCSL?

A: Yes. Both components share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, housing type, mounting features, and lead style. The series designation difference (RER40 versus RER60) does not affect functional interchangeability.

Q: Are there any dimensional differences between these parts?

A: No. Both components have identical dimensions: 0.600" L x 0.646" W (15.24mm x 16.41mm) with a maximum seated height of 0.335" (8.51mm).

Q: Do both parts meet the same military specifications?

A: Yes. Both the RER40F2000RCSL and RER60F2000RC02 comply with MIL-PRF-39009 military standards and carry identical failure rate ratings of R (0.01%).

Q: What is the difference between the RER40 and RER60 series designations?

A: The series designation reflects internal Vishay Dale product line organization. Both series maintain equivalent electrical performance and mechanical compatibility for this 200 Ohm 5W wirewound chassis mount resistor.

Q: Are there any compliance or certification differences?

A: Both parts share identical RoHS non-compliant status, MSL rating of 1 (Unlimited), ECCN classification (EAR99), and HTSUS code (8533.21.0080). The RER60F2000RC02 includes REACH status information available upon request.
