Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the RLR05C2673FPRSL and maintain full compliance with MIL-PRF-39017/05 military specifications. Selection among active alternatives should be based on:

Packaging Requirements: The main part uses bulk packaging. Substitutes RLR05C2673FPRSL, RLR05C2673FRRSL, RLR05C2673FSRSL, RLR05C2673FPR36, and RLR05C2673FPRE6 are available in Tape & Reel format, which may require process adaptation for manual assembly or reel-fed automated equipment.

Failure Rate Classification: RLR05C2673FSRSL offers the lowest failure rate (S, 0.001%), followed by RLR05C2673FRRSL (R, 0.01%), while RLR05C2673FPR36 and RLR05C2673FPRE6 maintain the same failure rate as the original part (P, 0.1%). Selection depends on system reliability requirements and mission profile.

Product Status: RLR05C2673FRRSL, RLR05C2673FSRSL, RLR05C2673FPR36, and RLR05C2673FPRE6 are all active products with confirmed inventory availability, ensuring long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2673FRRSL, RLR05C2673FSRSL, RLR05C2673FPR36, and RLR05C2673FPRE6 be used as direct replacements for RLR05C2673FPRSL?

A: Yes. All substitute parts maintain identical electrical specifications (267 kOhms ±1%, 0.125W, ±100ppm/°C, -65°C to 150°C operating range) and physical dimensions (0.066" Dia x 0.150" L). They are functionally interchangeable in circuit applications. The primary difference is packaging format (Tape & Reel vs. bulk) and failure rate classification.

Q: What is the difference between the substitute parts?

A: All substitutes share identical electrical and mechanical parameters. Differences are limited to packaging format and failure rate classification. RLR05C2673FSRSL provides the lowest failure rate (0.001%), RLR05C2673FRRSL provides intermediate reliability (0.01%), and RLR05C2673FPR36 and RLR05C2673FPRE6 match the original failure rate (0.1%). Packaging is Tape & Reel for all active substitutes.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel vs. bulk) does not affect electrical performance or circuit functionality. It impacts only assembly process compatibility and handling procedures. Tape & Reel packaging is standard for automated assembly lines, while bulk packaging suits manual assembly operations.

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

A: Yes. All listed substitutes are manufactured to MIL-PRF-39017/05 military specifications and maintain the same feature set: metal film composition, moisture resistance, and weldable terminations.

Q: Which substitute should I select for highest reliability?

A: RLR05C2673FSRSL offers the lowest failure rate (S classification, 0.001%) among available substitutes. Selection should align with system reliability requirements and mission criticality.
