Substitute Part Grouping Explanation

Substitute parts for the RLR07C1001FSRSL23 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Resistance Value: 1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -65°C to 150°C (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.090" Dia × 0.250" L (exact match required)
• Military Series: MIL-PRF-39017/01, RLR07 (exact match required)
• Failure Rate Classification: S (0.001%) (exact match required)

The RLR07C1001FSB14 meets all substitution criteria as a parametric equivalent within the same military RLR07 series.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FSB14 be used as a direct replacement for RLR07C1001FSRSL23?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (1 kOhm ±1%, 0.25W), composition (metal film), temperature characteristics (±100ppm/°C, -65°C to 150°C operating range), and mechanical dimensions (0.090" Dia × 0.250" L axial package). Both are qualified to MIL-PRF-39017/01 within the RLR07 military series.

Q: Are there any differences in packaging or termination between these parts?

A: No. Both parts use identical axial through-hole packaging with 2 terminations and matching physical dimensions. Both feature moisture-resistant construction with weldable terminations.

Q: What determines substitutability for this resistor category?

A: Substitutability is determined by exact matching of resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, package type, physical dimensions, and military qualification series. All these parameters must be identical for direct substitution.

Q: Do compliance differences affect substitution?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status, making them equivalent from a regulatory standpoint for applications where these designations are acceptable.

Q: What is the failure rate significance?

A: Both parts carry an S-class failure rate (0.001%), indicating military-grade reliability suitable for high-reliability applications. This classification is identical between the main part and substitute.
