Substitute Part Grouping Explanation

Substitute parts for the RWR80S1501FSBSL are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is determined by the following criteria:

• Identical resistance value: 1.5 kOhms
• Identical tolerance: ±1%
• Identical power rating: 2W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±20ppm/°C
• Identical operating temperature range: -55°C to 250°C
• Identical physical dimensions: 0.094" Dia x 0.406" L (2.39mm x 10.31mm)
• Same military series classification: MIL-PRF-39007, RWR80S
• Same moisture-resistant features

All substitute parts listed maintain these parameters without deviation, ensuring direct interchangeability in circuit applications.

Engineering Selection Recommendations

All three parts—RWR80S1501FSBSL, RWR80S1501FRB12, and RWR80S1501FSB12—are fully equivalent for direct substitution in military and aerospace applications. Selection should be based on the following factors:

• All parts maintain identical electrical specifications and physical dimensions
• All parts comply with MIL-PRF-39007 military standards
• All parts carry identical RoHS non-compliant and REACH Affected designations
• All parts are classified under the same ECCN (EAR99) and HTSUS code
• RWR80S1501FSBSL and RWR80S1501FSB12 share the same failure rate classification (S, 0.001%), indicating superior reliability performance
• RWR80S1501FRB12 carries a higher failure rate classification (R, 0.01%), which may be acceptable depending on application criticality
• Inventory availability varies across the three parts; selection may depend on procurement lead time requirements

Frequently Asked Questions (FAQ)

Q: Can RWR80S1501FRB12 and RWR80S1501FSB12 be used interchangeably with RWR80S1501FSBSL?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. They are all manufactured by Vishay Dale under the same military series classification (MIL-PRF-39007, RWR80S).

Q: What is the difference between these substitute parts?

A: The primary difference is the failure rate classification. RWR80S1501FSBSL and RWR80S1501FSB12 are rated at S (0.001%), while RWR80S1501FRB12 is rated at R (0.01%). This distinction reflects reliability performance under military standards. Inventory levels also differ across the three parts.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All three parts operate across the temperature range of -55°C to 250°C with a temperature coefficient of ±20ppm/°C, making them suitable for demanding military and aerospace environments.

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

A: All parts are classified as moisture-resistant wirewound resistors. While Moisture Sensitivity Level (MSL) is not applicable to these components, standard handling practices for through-hole resistors should be observed.

Q: Are these parts RoHS compliant?

A: No. All three parts are RoHS non-compliant. They are, however, REACH Affected and classified under ECCN EAR99.
