Substitute Part Grouping Explanation

Substitute parts for the RLR07C2741FSBSL are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

• Identical resistance value: 2.74 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 150°C
• Identical package type: Axial
• Identical physical dimensions: 0.090" Dia x 0.250" L (2.29mm x 6.35mm)
• Identical series specification: Military, MIL-PRF-39017/01, RLR07
• Identical failure rate classification: S (0.001%)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C2741FSBSL and RLR07C2741FSB14 are active products manufactured by Vishay Dale within the military-grade RLR07 series. Both parts comply with MIL-PRF-39017/01 specifications and carry identical regulatory classifications (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090). Selection between these parts should be based on inventory availability and procurement lead times, as all electrical, mechanical, and compliance parameters are identical. The RLR07C2741FSBSL currently maintains higher inventory levels (896 units) compared to RLR07C2741FSB14 (816 units).

Frequently Asked Questions (FAQ)

Q: Can RLR07C2741FSB14 be used as a direct replacement for RLR07C2741FSBSL?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, package type, physical dimensions, military series designation, and failure rate classification.

Q: Are there any differences in the axial package dimensions between these parts?

A: No. Both parts share identical physical dimensions of 0.090" diameter by 0.250" length (2.29mm x 6.35mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR07C2741FSBSL and RLR07C2741FSB14 are manufactured to MIL-PRF-39017/01 specifications and feature military-grade construction with moisture-resistant, weldable metal film composition.

Q: What is the significance of the different part number suffixes (FSBSL vs. FSB14)?

A: The suffix variation indicates different packaging or distribution configurations from Vishay Dale. However, the core electrical and mechanical specifications remain identical, making them functionally equivalent for circuit applications.

Q: Are both parts RoHS compliant?

A: No. Both RLR07C2741FSBSL and RLR07C2741FSB14 are classified as RoHS non-compliant. Applications requiring RoHS compliance must source alternative parts meeting those requirements.

Q: What regulatory certifications apply to both parts?

A: Both parts are REACH Affected, classified under ECCN EAR99, and assigned HTSUS code 8533.21.0090. These classifications are identical across both part numbers.
