Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C2433FPRSL is determined by strict equivalence across the following parameters:

Resistance value: 243 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 type: Axial (exact match required)
Physical dimensions: 0.066" Dia × 0.150" L (exact match required)
Series: RLR05 military series (exact match required)

All identified substitute parts meet these criteria. Variations in packaging format (bulk vs. Tape & Reel) and failure rate classifications do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All four substitute parts are direct electrical and mechanical equivalents to the RLR05C2433FPRSL. Selection among these alternatives should be based on:

Product Status: RLR05C2433FRRSL, RLR05C2433FSRSL, RLR05C2433FPR36, and RLR05C2433FPRE6 are all active products with confirmed inventory availability, eliminating obsolescence risk.

Failure Rate Classification: RLR05C2433FSRSL offers the lowest failure rate (S-class, 0.001%), followed by RLR05C2433FRRSL (R-class, 0.01%). RLR05C2433FPR36 and RLR05C2433FPRE6 maintain P-class failure rates (0.1%), matching the original part's specification.

Packaging Format: RLR05C2433FPR36 and RLR05C2433FPRE6 are supplied in Tape & Reel format, suitable for automated assembly. RLR05C2433FRRSL and RLR05C2433FSRSL are also Tape & Reel packaged. Bulk packaging availability is limited to discontinued inventory.

Compliance: All substitute parts maintain identical RoHS non-compliance status, REACH affected designation, and EAR99 ECCN classification as the original part.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2433FRRSL, RLR05C2433FSRSL, RLR05C2433FPR36, and RLR05C2433FPRE6 be used interchangeably with RLR05C2433FPRSL?

A: Yes. All four parts are direct substitutes. They share identical resistance value (243 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), package type (axial), and physical dimensions (0.066" Dia × 0.150" L). Differences in failure rate classification and packaging format do not affect electrical or mechanical compatibility.

Q: What is the difference between the failure rate classifications (P, R, S)?

A: Failure rate classifications indicate predicted reliability levels under MIL-PRF-39017/05 military specifications. P-class (0.1%) represents standard military-grade reliability. R-class (0.01%) and S-class (0.001%) represent enhanced reliability levels with lower predicted failure rates. Selection depends on application reliability requirements.

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

A: Yes. RLR05C2433FRRSL, RLR05C2433FSRSL, RLR05C2433FPR36, and RLR05C2433FPRE6 are all supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly processes.

Q: Do the substitute parts maintain the same military specifications as the original?

A: Yes. All substitute parts are classified as military-grade components within the RLR05 series, comply with MIL-PRF-39017/05 standards, and maintain moisture resistance and weldability features identical to the original RLR05C2433FPRSL.

Q: What is the inventory status of each substitute part?

A: RLR05C2433FRRSL has 997 pieces in stock, RLR05C2433FSRSL has 891 pieces, RLR05C2433FPR36 has 800 pieces, and RLR05C2433FPRE6 has 1030 pieces available as new original stock.
