Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C8251FPBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 8.25 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.250" L
• Military qualification: MIL-PRF-39017/01, RLR07 series
• Termination count: 2

The identified substitute part RLR07C8251FSB14 maintains identical electrical and mechanical specifications. Differences in failure rate classification do not affect functional interchangeability in circuit applications where the specified electrical parameters are the controlling requirement.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C8251FPBSL and RLR07C8251FSB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Failure rate classification needs for specific application reliability targets
• Compliance requirements: both parts are RoHS non-compliant and REACH Affected with EAR99 export classification

The substitute part RLR07C8251FSB14 offers a lower failure rate classification (S: 0.001% versus P: 0.1%), which may be advantageous for high-reliability military or aerospace applications where failure rate performance is a documented requirement.

Frequently Asked Questions (FAQ)

Q: Can RLR07C8251FSB14 be used as a direct replacement for RLR07C8251FPBSL?

A: Yes. Both parts are electrically and mechanically identical with matching resistance value (8.25 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating range (-65°C to 150°C), and axial package dimensions (0.090" Dia × 0.250" L). Both comply with MIL-PRF-39017/01 military specifications.

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

A: The primary difference is the failure rate classification. RLR07C8251FSB14 has a lower failure rate (S: 0.001%) compared to RLR07C8251FPBSL (P: 0.1%). Both parts maintain identical functional specifications and military qualification.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).

Q: Can these parts be used in PCB assembly with automated equipment?

A: Yes. Both parts are axial through-hole components with standard 2-termination configuration and identical physical dimensions, compatible with standard PCB assembly processes and through-hole insertion equipment.

Q: Are moisture-resistant and weldable properties identical?

A: Yes. Both parts feature military-grade moisture-resistant and weldable metal film construction as specified in the MIL-PRF-39017/01 series.
