Substitute Part Grouping Explanation

Substitute parts for the RLR20C1001GSBSL are identified based on strict parametric equivalence across the following critical criteria:

• Resistance value: 1 kOhms
• Tolerance: ±2%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package: Axial
• Physical dimensions: 0.138" Dia × 0.375" L
• Termination count: 2
• Military series compliance: MIL-PRF-39017/02, RLR20 base product

The RLR20C1001GSB14 meets all specified parameters and qualifies as a parametric equivalent. Both parts share identical electrical characteristics, mechanical form factor, and military-grade specifications, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR20C1001GSBSL and RLR20C1001GSB14 are active production parts manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on:
