Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C2742FSBSL is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RLR07C2742FSB14 qualifies as a direct parametric equivalent based on the following criteria:

• Identical resistance value: 27.4 kOhms
• Matching tolerance specification: ±1%
• Equivalent power rating: 0.25W (1/4W)
• Same composition: Metal Film
• Identical temperature coefficient: ±100 ppm/°C
• Matching operating temperature range: -65°C to +150°C
• Same package configuration: Axial
• Identical physical dimensions: 0.090" Dia × 0.250" L
• Matching military series designation: RLR07, MIL-PRF-39017/01
• Equivalent failure rate classification: S (0.001%)

Both parts share the same base product number (RLR07) and maintain identical feature sets including military-grade construction, moisture resistance, and weldability. The substitution is valid for direct replacement in circuit applications without modification to board layout, schematic, or assembly procedures.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C2742FSBSL and RLR07C2742FSB14 maintain active product status from Vishay Dale and are suitable for direct substitution in military and aerospace applications. Selection between these parts should be based on availability and procurement lead times, as all electrical performance, mechanical compatibility, and environmental specifications are identical.

Both parts are RoHS non-compliant and REACH Affected, maintaining consistent regulatory status. The identical failure rate classification (S, 0.001%) ensures equivalent reliability performance in mission-critical applications. Military-grade construction with moisture resistance and weldability is preserved across both part numbers, supporting applications requiring MIL-PRF-39017/01 compliance.

Frequently Asked Questions (FAQ)

Q: Can RLR07C2742FSB14 be used as a direct replacement for RLR07C2742FSBSL?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package configuration, and physical dimensions. Direct substitution is valid without circuit modification or board redesign.

Q: Are there any differences in military compliance between these parts?

A: No. Both parts are manufactured to the same MIL-PRF-39017/01 standard within the RLR07 series and maintain identical military-grade features including moisture resistance and weldability.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts share identical axial package dimensions of 0.090" diameter × 0.250" length (2.29mm × 6.35mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the difference between the part numbers?

A: The part numbers differ only in their suffix designations (FSBSL versus FSB14). These designations reflect internal Vishay Dale manufacturing or packaging variations but do not affect electrical performance, mechanical compatibility, or functional specifications.

Q: Are both parts suitable for high-reliability applications?
