Substitute Part Grouping Explanation

Substitution for RLR05C1183FPRSL is determined by strict equivalence across all electrical and mechanical parameters. The following criteria define valid substitutes:

Resistance value: 118 kOhms (exact match)
Tolerance: ±1% (exact match)
Power rating: 0.125W / 1/8W (exact match)
Composition: Metal Film (exact match)
Temperature coefficient: ±100ppm/°C (exact match)
Operating temperature range: -65°C to 150°C (exact match)
Package: Axial through-hole (exact match)
Physical dimensions: 0.066" Dia × 0.150" L (exact match)
Series compliance: MIL-PRF-39017/05, RLR05 (exact match)
Termination count: 2 (exact match)

Substitute parts differ only in packaging format (Tape & Reel vs. bulk) and failure rate classification, which do not affect electrical or mechanical compatibility. All substitutes maintain active product status.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to RLR05C1183FPRSL. Selection among active alternatives should be based on:

Product Status: All substitutes maintain active product status, ensuring continued availability and supply chain stability compared to the discontinued main part.

Failure Rate Classification: RLR05C1183FSRSL offers superior reliability with S-class failure rate (0.001%) versus P-class (0.1%) for other substitutes. This distinction applies to applications requiring enhanced reliability metrics.

Packaging Format: RLR05C1183FPRSL uses bulk packaging, while all substitutes are supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and provides better component protection during storage and handling.

Compliance & Certifications: All parts maintain identical MIL-PRF-39017/05 military specification compliance, RoHS non-compliance status, REACH affected designation, and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1183FSRSL replace RLR05C1183FPRSL in existing designs?

A: Yes. RLR05C1183FSRSL is a direct electrical and mechanical equivalent with identical resistance, tolerance, power rating, temperature coefficient, operating range, and physical dimensions. The only differences are packaging format (Tape & Reel vs. bulk) and failure rate class (S vs. P), neither of which affects circuit performance.

Q: What is the difference between P-class and S-class failure rates?

A: Failure rate classification indicates expected component reliability under specified conditions. S-class (0.001%) represents lower failure rate than P-class (0.1%). Selection depends on application reliability requirements; both are valid for standard military applications.

Q: Are all substitutes compatible with automated assembly equipment?

A: All substitute parts are supplied in Tape & Reel packaging, which is the standard format for automated pick-and-place assembly. The original RLR05C1183FPRSL uses bulk packaging and may require manual handling or tape conversion for automated processes.

Q: Do packaging differences affect electrical performance?

A: No. Packaging format (Tape & Reel or bulk) does not affect electrical characteristics, component performance, or circuit compatibility. It only impacts handling, storage, and assembly methodology.

Q: Are all substitutes compliant with the same military specifications?

A: Yes. All parts comply with MIL-PRF-39017/05 and are part of the RLR05 military resistor series. Compliance status, RoHS designation, REACH status, and ECCN classification are identical across all parts.
