RLR05C1001FPB14 Equivalent & Substitute Parts

Part Overview

The RLR05C1001FPB14 is a 1 kOhms ±1% metal film axial resistor rated at 0.125W (1/8W) manufactured by Vishay Dale. This component is part of the military-grade RLR05 series, compliant with MIL-PRF-39017/05 specification. The part features moisture-resistant construction with weldable terminations, designed for through-hole applications in military and aerospace environments. The component maintains active product status with 885 units currently in stock.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter set.

Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C1001FPB14 is determined by strict equivalence across the following critical parameters:

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

All substitute parts listed maintain identical electrical and mechanical specifications. Differences exist only in failure rate classification, which reflects component reliability grading under military standards but does not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—RLR05C1001FPB14, RLR05C1001FRB14, and RLR05C1001FSB14—are functionally equivalent for circuit applications requiring a 1 kOhms ±1% metal film axial resistor. Selection between these alternatives should be based on:

Failure Rate Requirements: RLR05C1001FSB14 offers the lowest failure rate (0.001%), suitable for high-reliability applications. RLR05C1001FRB14 provides intermediate reliability (0.01%), while RLR05C1001FPB14 meets standard military reliability (0.1%).

Inventory Availability: Current stock levels are 996 units (RLR05C1001FSB14), 1035 units (RLR05C1001FRB14), and 885 units (RLR05C1001FPB14). Selection may be driven by procurement lead times and supply chain requirements.

Regulatory Compliance: All three parts share identical RoHS non-compliance status, REACH-affected designation, and EAR99 export classification. No compliance advantage exists between alternatives.

Military Specification Compliance: All parts conform to MIL-PRF-39017/05 and maintain active product status with Vishay Dale.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FRB14 and RLR05C1001FSB14 be used interchangeably with RLR05C1001FPB14 in circuit designs?

A: Yes. All three parts are electrically and mechanically identical. They share the same resistance value (1 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and physical dimensions (0.066" Dia x 0.150" L). The only difference is failure rate classification under military standards, which does not affect functional performance in circuit applications.

Q: What does the failure rate designation mean?

A: Failure rate classifications (P, R, S) indicate component reliability levels under MIL-PRF-39017/05. P (0.1%) represents standard military-grade reliability, R (0.01%) represents enhanced reliability, and S (0.001%) represents the highest reliability level. Selection depends on application criticality and reliability requirements.

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

A: No. All three parts are supplied in identical axial package configuration with dimensions of 0.066" diameter by 0.150" length (1.68mm x 3.81mm). They are directly interchangeable in through-hole PCB layouts.

Q: What is the difference between these parts and non-military RLR05 variants?

A: The RLR05C1001FPB14, RLR05C1001FRB14, and RLR05C1001FSB14 are all military-grade components compliant with MIL-PRF-39017/05, featuring moisture-resistant construction and weldable terminations. These specifications distinguish them from commercial-grade alternatives.

Q: Are these parts RoHS compliant?

A: No. All three parts are RoHS non-compliant and REACH-affected. They are suitable for military, aerospace, and applications where RoHS exemptions apply.
