Substitute Part Grouping Explanation

Substitute parts for the RLR07C1001FSBSL are identified based on strict electrical and mechanical parameter matching within the RLR07 military resistor series. The following parameters determine substitution eligibility:

• Resistance value: 1 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: Axial
• Physical dimensions: 0.090" Dia x 0.250" L (2.29mm x 6.35mm)
• Series compliance: MIL-PRF-39017/01, RLR07

All identified substitutes maintain these core parameters. Variations in failure rate classification do not affect functional interchangeability in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RLR07C1001FSBSL, RLR07C1001FRB14, and RLR07C1001FSB14—are active production components from Vishay Dale within the military-qualified RLR07 series. Selection between these parts is based on availability and failure rate requirements:

• RLR07C1001FSBSL and RLR07C1001FSB14 both carry failure rate classification S (0.001%), suitable for applications requiring lower failure rate specifications.
• RLR07C1001FRB14 carries failure rate classification R (0.01%), appropriate for applications with less stringent reliability requirements.

All parts maintain identical electrical performance, temperature characteristics, and mechanical compatibility. Compliance status (RoHS non-compliant, REACH Affected) is uniform across all three options.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FRB14 be used as a direct replacement for RLR07C1001FSBSL?

A: Yes. Both parts share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The difference in failure rate classification (R vs. S) does not affect functional interchangeability in standard circuit applications. Selection depends on system reliability requirements.

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

A: No. All three parts are axial-packaged resistors with identical physical dimensions of 0.090" Dia x 0.250" L (2.29mm x 6.35mm). They are mechanically and electrically interchangeable in PCB layouts and through-hole applications.

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

A: Failure rate classification indicates the expected percentage of component failures per 1,000 hours of operation under specified conditions. RLR07C1001FSBSL and RLR07C1001FSB14 (S classification, 0.001%) are suitable for high-reliability applications. RLR07C1001FRB14 (R classification, 0.01%) is appropriate for standard military and industrial applications. The choice depends on system-level reliability specifications.

Q: Do all substitute parts comply with MIL-PRF-39017/01?

A: Yes. All three parts are certified to MIL-PRF-39017/01 specification and are classified as military-grade components within the RLR07 series.

Q: Are there any environmental or compliance considerations when selecting between these parts?

A: All three parts share identical compliance status: RoHS non-compliant and REACH Affected. Environmental and regulatory considerations do not differentiate these options.
