Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C7500FPBSL is determined by the following critical parameters:

• Resistance value: 750 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Series compliance: MIL-PRF-39017/01, RLR07 base product

The identified substitute part RLR07C7500FSB14 matches all critical electrical and mechanical parameters. Both parts are manufactured by Vishay Dale within the same military-grade RLR07 series and maintain identical specifications for resistance, tolerance, power rating, composition, package configuration, and operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C7500FPBSL and RLR07C7500FSB14 are active production parts manufactured by Vishay Dale and are suitable for direct substitution in military-grade applications. The parts share identical electrical specifications, physical dimensions, and compliance certifications. The primary distinction is the failure rate specification: RLR07C7500FSB14 carries a lower failure rate (S: 0.001%) compared to RLR07C7500FPBSL (P: 0.1%), which may be relevant for high-reliability applications. Both parts maintain RoHS non-compliant and REACH Affected status with EAR99 export classification. Selection between these parts should be based on availability, failure rate requirements, and application-specific reliability criteria.

Frequently Asked Questions (FAQ)

Q: Can RLR07C7500FSB14 be used as a direct replacement for RLR07C7500FPBSL?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (750 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and physical dimensions (0.090" Dia x 0.250" L). Both comply with MIL-PRF-39017/01 specifications.

Q: What is the difference between these two parts?

A: The primary difference is the failure rate specification. RLR07C7500FSB14 has a failure rate of S (0.001%), while RLR07C7500FPBSL has a failure rate of P (0.1%). All other electrical, mechanical, and compliance parameters are identical.

Q: Are there any package or footprint differences?

A: No. Both parts use identical axial through-hole packaging with the same physical dimensions of 0.090" Dia x 0.250" L (2.29mm x 6.35mm). They are mechanically interchangeable on PCBs designed for axial resistors.

Q: Do these parts have the same compliance certifications?

A: Yes. Both parts share identical RoHS non-compliant status, REACH Affected designation, EAR99 export classification, and HTSUS code 8533.21.0090.

Q: Which part should I select for high-reliability applications?

A: RLR07C7500FSB14 is the appropriate choice for high-reliability applications due to its lower failure rate specification (S: 0.001% versus P: 0.1%).
