Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the RLR05C1004FPRSL. Selection among active alternatives should be based on the following criteria:

For applications requiring lowest failure rate: RLR05C1004FRRSL offers R-class (0.01%) failure rate, providing enhanced reliability for critical military and aerospace applications.

For standard military applications: RLR05C1004FPRE5, RLR05C1004FPRE6, RLR05C1004FPRE7, RLR05C1004FPRE8, and RLR05C1004FPR36 all provide P-class (0.1%) failure rate with active product status and consistent inventory availability.

For applications with relaxed reliability requirements: RLR05C1004FMRSL offers M-class (1%) failure rate as an active alternative.

All substitute parts maintain MIL-PRF-39017/05 compliance, moisture resistance, and weldability characteristics. RoHS non-compliance status is consistent across all variants. Packaging configuration (Tape & Reel) differs from the original part's bulk packaging but does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1004FMRSL replace RLR05C1004FPRSL in military applications?

A: Yes. Both parts meet identical electrical specifications (1 MOhm ±1%, 0.125W, ±100ppm/°C, -65°C to 150°C) and MIL-PRF-39017/05 compliance. The difference is failure rate classification: M-class (1%) versus P-class (0.1%). Selection depends on application reliability requirements.

Q: What is the difference between RLR05C1004FRRSL and other substitutes?

A: RLR05C1004FRRSL is classified as R-class with 0.01% failure rate, the lowest among all alternatives. All other electrical and mechanical parameters are identical. This variant is specified for applications requiring maximum reliability.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All active substitute parts are supplied in Tape & Reel (TR) configuration. The original RLR05C1004FPRSL was supplied in bulk packaging. Tape & Reel packaging is standard for production environments and does not affect component performance.

Q: Can I use RLR05C1004FPRE5, FPRE6, FPRE7, or FPRE8 interchangeably?

A: Yes. These four part numbers are parametrically equivalent with identical electrical specifications, failure rate (P-class, 0.1%), and product status (Active). Differences in part number suffixes reflect manufacturing date codes or internal tracking but do not indicate functional differences.

Q: Is the RLR05C1004FPRSL still available for new designs?

A: No. The RLR05C1004FPRSL is discontinued at DiGi Electronics. For new designs, specify one of the active alternatives: RLR05C1004FMRSL, RLR05C1004FRRSL, RLR05C1004FPR36, RLR05C1004FPRE5, RLR05C1004FPRE6, RLR05C1004FPRE7, RLR05C1004FPRE8, or RLR05C1004FPRSL19.

Q: Do all substitutes maintain the same physical dimensions?

A: Yes. All parts share identical axial package dimensions: 0.066" diameter × 0.150" length (1.68mm × 3.81mm). PCB layout and mechanical fit are unchanged across all alternatives.
