Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C7501FPB14 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 7.5 kOhms (exact match required)
  • Tolerance: ±1% (exact match required)
  • Power rating: 0.25W / 1/4W (exact match required)
  • Composition: Metal Film (exact match required)
  • Package configuration: Axial through-hole (exact match required)
  • Temperature coefficient: ±100ppm/°C (exact match required)
  • Operating temperature range: -65°C to 150°C (exact match required)
  • Physical dimensions: 0.090" Dia × 0.250" L (exact match required)
  • Military specification compliance: MIL-PRF-39017/01 (exact match required)

The RLR07C7501FSB14 qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is the failure rate classification, which does not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

Both RLR07C7501FPB14 and RLR07C7501FSB14 are active products manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on the following criteria:

RLR07C7501FPB14 is appropriate for applications where standard military-grade reliability (failure rate P: 0.1%) meets design requirements and inventory availability is prioritized.

RLR07C7501FSB14 is appropriate for applications requiring enhanced reliability performance (failure rate S: 0.001%) or where procurement lead times necessitate alternative sourcing. This part carries a lower failure rate classification, indicating superior long-term reliability characteristics.

Both parts maintain identical compliance status regarding RoHS non-compliance and REACH applicability. Selection should align with specific reliability requirements and supply chain constraints of the application.

Frequently Asked Questions (FAQ)

Q: Can RLR07C7501FSB14 be used as a direct replacement for RLR07C7501FPB14?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The parts are pin-compatible and occupy identical physical space in axial through-hole applications.

Q: What is the difference between failure rate P and failure rate S?

A: Failure rate P (0.1%) and failure rate S (0.001%) represent different reliability classifications under military specifications. Failure rate S indicates a lower predicted failure rate, making RLR07C7501FSB14 suitable for applications with higher reliability demands. Both parts function identically in circuit operation.

Q: Are there any package or dimensional differences between these parts?

A: No. Both parts share identical physical dimensions of 0.090" diameter by 0.250" length (2.29mm × 6.35mm) and are configured as axial through-hole components. They are mechanically interchangeable in PCB layouts and assembly processes.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR07C7501FPB14 and RLR07C7501FSB14 comply with MIL-PRF-39017/01 military specification and are classified within the RLR07 series. Both incorporate military-grade features including moisture resistance and weldability.

Q: What compliance considerations apply to both parts?

A: Both parts are RoHS non-compliant and REACH Affected. They carry identical regulatory classifications and should be evaluated against the same compliance requirements for the target application.
