Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RER75F2R00PCSL 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 ~ 250°C
• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box
• Military series compliance: MIL-PRF-39009, RER75

The RER75F2R00RC02 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, physical dimensions (1.968" L x 1.140" W, 49.99mm x 28.96mm), and mounting characteristics, making them directly interchangeable in applications requiring this resistor specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RER75F2R00PCSL and RER75F2R00RC02 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The RER75F2R00RC02 features a lower failure rate classification (R at 0.01% versus P at 0.1%), indicating enhanced reliability performance. Both parts maintain RoHS non-compliant status and are subject to the same export control classification (EAR99). Moisture sensitivity level is equivalent at MSL 1 (Unlimited) for both variants. The RER75F2R00RC02 offers REACH compliance information availability, which may be relevant for certain regulatory environments. Inventory availability is comparable, with the RER75F2R00RC02 showing slightly higher stock levels (965 pieces versus 922 pieces).

Frequently Asked Questions (FAQ)

Q: Are RER75F2R00PCSL and RER75F2R00RC02 directly interchangeable?

A: Yes. Both parts are parametric equivalents with identical resistance (2 Ohms), tolerance (±1%), power rating (30W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 250°C), physical dimensions, and mounting characteristics. They are directly interchangeable in applications requiring this specification.

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

A: The primary differences are the failure rate classification (RER75F2R00RC02 has R at 0.01% versus RER75F2R00PCSL at P at 0.1%) and REACH compliance information availability for the RC02 variant. All electrical and mechanical parameters are identical.

Q: Do both parts meet military specifications?

A: Yes. Both the RER75F2R00PCSL and RER75F2R00RC02 are part of the Military MIL-PRF-39009 RER75 series and meet military-grade specifications for wirewound chassis mount resistors.

Q: What is the physical package configuration?

A: Both parts feature an Axial, Box package type with aluminum housing, flanged mounting, and solder lug leads. Dimensions are 1.968" L x 1.140" W (49.99mm x 28.96mm) with a maximum seated height of 0.625" (15.87mm).

Q: Are there RoHS compliance considerations?

A: Both parts are RoHS non-compliant. Applications requiring RoHS compliance cannot use either of these components.

Q: What is the moisture sensitivity level?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
