RLR05C3653FPRSL Equivalent & Substitute Parts

Part Overview

The RLR05C3653FPRSL is a 365 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, designed to MIL-PRF-39017/05 specifications with moisture-resistant and weldable characteristics. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C3653FPRSL is determined by strict equivalence across the following parameters:

Resistance value: 365 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.125W / 1/8W (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 configuration: Axial through-hole (exact match required)
Physical dimensions: 0.066" Dia × 0.150" L (exact match required)
Series compliance: MIL-PRF-39017/05, RLR05 (exact match required)

All identified substitute parts maintain identical electrical and mechanical specifications. Substitutes are differentiated only by packaging format (Tape & Reel or Bulk) and product status (Active vs. Discontinued).

Engineering Selection Recommendations

All four substitute parts are direct functional equivalents of the RLR05C3653FPRSL. Selection among active alternatives should be based on procurement requirements:

RLR05C3653FRRSL (Tape & Reel, Active): Provides improved reliability with R-class failure rate (0.01%) compared to the original P-class rating (0.1%). Maintains identical electrical and mechanical specifications with active product status.

RLR05C3653FSB14 (Bulk, Active): Offers the highest reliability classification with S-class failure rate (0.001%). Suitable for applications requiring bulk quantities. Identical electrical and mechanical performance.

RLR05C3653FPRE5 and RLR05C3653FPRE6 (Tape & Reel, Active): Both maintain P-class failure rate matching the original part. Active product status ensures continued availability. Tape & Reel packaging supports automated assembly processes.

All substitutes maintain MIL-PRF-39017/05 military specification compliance, moisture resistance, weldability, and RoHS non-compliant status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can RLR05C3653FRRSL be used as a direct replacement for RLR05C3653FPRSL?

A: Yes. Both parts share identical resistance (365 kΩ), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating range (-65°C to 150°C), and physical dimensions (0.066" × 0.150"). The difference is packaging format (Tape & Reel vs. original Tape & Reel) and improved failure rate classification.

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Bulk packaging is supplied loose and is typically used for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical.

Q: Are all substitutes MIL-PRF-39017/05 compliant?

A: Yes. All substitute parts are manufactured to MIL-PRF-39017/05 specifications and are part of the RLR05 military-grade series.

Q: What does the failure rate classification mean?

A: Failure rate classifications (P, R, S) indicate predicted failure rates under specified conditions. S-class (0.001%) represents the lowest failure rate, followed by R-class (0.01%), then P-class (0.1%). Higher reliability classifications may be selected based on application criticality.

Q: Can I mix packaging formats in the same assembly?

A: Yes, provided your assembly process accommodates both Tape & Reel and Bulk formats. Electrical and mechanical performance are identical across all packaging options.
