Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C3003GSB1423 is determined by strict equivalence across the following parameters:

• Resistance value: 300 kOhms
• Tolerance: ±2%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Military series compliance: MIL-PRF-39017/01, RLR07 base product

The identified substitute maintains all electrical and mechanical specifications without deviation. Substitution is valid only when all parameters remain identical.
