Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1503FSB14 is determined by strict equivalence across the following critical parameters:

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

The identified substitute maintains all electrical specifications and mechanical compatibility. Variations in failure rate classification and inventory status do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1503FSB14 and RLR07C1503FRB14 are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Failure rate requirements: RLR07C1503FSB14 provides S-class (0.001%) failure rate; RLR07C1503FRB14 provides R-class (0.01%) failure rate
• Inventory availability: Both parts maintain adequate stock levels
• Compliance requirements: Both parts carry identical RoHS non-compliant and REACH Affected designations
• Military specification adherence: Both parts conform to MIL-PRF-39017/01

Frequently Asked Questions (FAQ)

Q: Can RLR07C1503FRB14 be used as a direct replacement for RLR07C1503FSB14?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The difference in failure rate classification does not affect functional interchangeability in standard circuit applications.

Q: What is the significance of the failure rate difference between these parts?

A: Failure rate classification reflects expected reliability performance under specified conditions. RLR07C1503FSB14 (S-class, 0.001%) indicates lower expected failure rate compared to RLR07C1503FRB14 (R-class, 0.01%). Selection should align with application reliability requirements and military specification mandates.

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

A: No. Both parts share identical axial package configuration with dimensions of 0.090" diameter by 0.250" length (2.29mm x 6.35mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: Do compliance and certification requirements differ between these parts?

A: No. Both parts carry identical RoHS non-compliant and REACH Affected designations. Compliance status is uniform across the substitute group.

Q: What determines substitution eligibility for military-grade resistors in the RLR07 series?

A: Substitution eligibility is strictly determined by equivalence in resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, physical dimensions, and military series compliance per MIL-PRF-39017/01. All these parameters must match exactly.
