• 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
• Series compliance: MIL-PRF-39017/01, RLR07

All identified substitutes maintain these core parameters. Variations in failure rate classification do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and identical electrical and mechanical specifications. Selection between RLR07C1503FSBSL, RLR07C1503FRB14, and RLR07C1503FSB14 is based on failure rate classification and inventory availability:

• RLR07C1503FSBSL and RLR07C1503FSB14 both carry S-class failure rate (0.001%), suitable for applications requiring higher reliability margins.
• RLR07C1503FRB14 carries R-class failure rate (0.01%), appropriate for standard military applications.
• All parts comply with MIL-PRF-39017/01 military specification and maintain identical compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99).

Frequently Asked Questions (FAQ)

Q: Can RLR07C1503FRB14 replace RLR07C1503FSBSL in military applications?

A: Yes. Both parts meet MIL-PRF-39017/01 specification with identical electrical parameters (150 kOhms ±1%, 0.25W, ±100ppm/°C) and physical dimensions (0.090" Dia x 0.250" L). The difference in failure rate classification (R vs. S) does not affect functional compatibility. Application-specific reliability requirements determine suitability.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical axial package dimensions of 0.090" Dia x 0.250" L (2.29mm x 6.35mm), ensuring direct mechanical compatibility in PCB layouts and through-hole applications.

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

A: Failure rate classification reflects expected failure frequency under specified conditions. S-class (0.001%) indicates lower expected failure rate than R-class (0.01%). Both classifications comply with military standards; selection depends on application reliability requirements and mission criticality.

Q: Are all three parts RoHS compliant?

A: No. All three parts are RoHS non-compliant. If RoHS compliance is required, alternative resistor families must be evaluated.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts maintain identical operating temperature range (-65°C to 150°C) and temperature coefficient (±100ppm/°C), ensuring equivalent performance across the full temperature spectrum.
