Substitute Part Grouping Explanation

Substitution eligibility for RLR05C1001FPBSL is determined by strict equivalence across the following parameters:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package: Axial
• Physical dimensions: 0.066" Dia × 0.150" L (1.68mm × 3.81mm)
• Series: Military, MIL-PRF-39017/05, RLR05
• Features: Military, Moisture Resistant, Weldable

The identified substitute parts RLR05C1001FRB14 and RLR05C1001FSB14 maintain identical electrical and mechanical specifications. Differentiation between parts is based solely on failure rate classification, which reflects manufacturing process control levels and does not alter functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090). Selection between RLR05C1001FPBSL, RLR05C1001FRB14, and RLR05C1001FSB14 is based on failure rate requirements and inventory availability:

• RLR05C1001FPBSL: Failure rate P (0.1%), suitable for general military applications
• RLR05C1001FRB14: Failure rate R (0.01%), for applications requiring lower failure rate classification
• RLR05C1001FSB14: Failure rate S (0.001%), for high-reliability military applications with stringent failure rate specifications

All parts are electrically and mechanically interchangeable. Selection should be driven by application failure rate requirements and procurement availability.

Frequently Asked Questions (FAQ)

Q: Are RLR05C1001FRB14 and RLR05C1001FSB14 direct replacements for RLR05C1001FPBSL?

A: Yes. Both substitute parts are electrically and mechanically identical. They share the same resistance value (1 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and axial package dimensions (0.066" Dia × 0.150" L). The only difference is the failure rate classification.

Q: What determines which part to select?

A: Selection is based on failure rate requirements. RLR05C1001FPBSL carries failure rate P (0.1%), RLR05C1001FRB14 carries failure rate R (0.01%), and RLR05C1001FSB14 carries failure rate S (0.001%). Choose the part whose failure rate meets your application specifications.

Q: Will these parts fit in the same PCB footprint?

A: Yes. All three parts have identical physical dimensions (0.066" Dia × 0.150" L / 1.68mm × 3.81mm) and axial package configuration with 2 terminations. No PCB layout modifications are required.

Q: Are there any compliance differences between these parts?

A: No. All three parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Regulatory and environmental classifications are equivalent.

Q: Can I substitute based on inventory availability?

A: Yes, provided the failure rate classification of the substitute part meets or exceeds your application requirements. RLR05C1001FSB14 (failure rate S) can substitute for any application requiring RLR05C1001FPBSL (failure rate P) or RLR05C1001FRB14 (failure rate R). RLR05C1001FRB14 can substitute for RLR05C1001FPBSL but not for applications specifically requiring failure rate S.
