Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR32C1001GPBSL is determined by the following critical parameters: resistance value (1 kOhms), power rating (1W), package type (Axial), composition (Metal Film), operating temperature range (-65°C ~ 150°C), and military series compliance (MIL-PRF-39017/03, RLR32).

Two substitute parts are identified:

Direct Substitute (RLR32C1001GRB14): Maintains identical electrical specifications including 1 kOhms resistance, ±2% tolerance, 1W power rating, and ±100ppm/°C temperature coefficient. The primary difference is the failure rate classification (R at 0.01% versus P at 0.1%), indicating improved reliability characteristics while preserving all functional parameters.

Upgrade Substitute (RLR32C1001FRB14): Shares the same resistance value (1 kOhms), power rating (1W), package type (Axial), and operating temperature range. The key difference is tighter tolerance specification (±1% versus ±2%), providing enhanced precision. This part also features the improved failure rate classification (R at 0.01%).

Parameter Comparison

Engineering Selection Recommendations

All three parts—RLR32C1001GPBSL, RLR32C1001GRB14, and RLR32C1001FRB14—are active products manufactured by Vishay Dale within the military-grade RLR32 series. All maintain compliance with MIL-PRF-39017/03 specifications and share identical physical dimensions, enabling direct mechanical interchangeability in axial through-hole applications.

RLR32C1001GRB14 serves as a direct functional equivalent with improved reliability (failure rate R versus P). This part is suitable for applications where the original specification is met and enhanced reliability is beneficial.

RLR32C1001FRB14 provides tighter tolerance (±1% versus ±2%) while maintaining all other electrical and mechanical characteristics. This upgrade option is applicable in circuits requiring higher precision resistor values.

All parts carry identical regulatory classifications (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090), ensuring consistent compliance documentation across substitution scenarios.

Frequently Asked Questions (FAQ)
