RLR05C1001FSRSL Equivalent & Substitute Parts

Part Overview

The RLR05C1001FSRSL is a 1 kOhms ±1% metal film axial resistor rated at 0.125W (1/8W) manufactured by Vishay Dale. This component is designed for military applications per MIL-PRF-39017/05 specification and features moisture-resistant, weldable construction. The part is currently active in production with 858 units in stock. Substitute parts may be required due to packaging format availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The RLR05C1001FSRSL and its substitute RLR05C1001FSRE6 are parametrically equivalent based on the following critical 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
• Physical dimensions: 0.066" Dia x 0.150" L (1.68mm x 3.81mm)
• Military series classification: MIL-PRF-39017/05, RLR05
• Failure rate: S (0.001%)

The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both maintain identical electrical performance and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C1001FSRSL and RLR05C1001FSRE6 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement logistics:

• RLR05C1001FSRSL (Tape & Reel) is suitable for high-volume automated assembly operations requiring continuous reel feeding.
• RLR05C1001FSRE6 (Cut Tape) is suitable for lower-volume applications, manual assembly, or situations where individual component handling is preferred.

Both parts comply with MIL-PRF-39017/05 military specification and maintain the same failure rate classification. Neither part is RoHS compliant; both are REACH affected and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSRE6 be used as a direct replacement for RLR05C1001FSRSL?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid for any application where the component specifications are met.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly or lower-volume production runs.

Q: Are there any performance differences between these substitute parts?

A: No. Both parts have identical resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and failure rate. Performance is equivalent across all electrical and thermal parameters.

Q: Do both parts meet military specifications?

A: Yes. Both RLR05C1001FSRSL and RLR05C1001FSRE6 are manufactured to MIL-PRF-39017/05 specification and are classified as military-grade components with moisture-resistant, weldable construction.

Q: What factors should determine which substitute to select?

A: Selection should be based on assembly method (automated versus manual), production volume, inventory availability, and packaging handling requirements. Electrical performance and reliability are identical between both parts.
