Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C2491FSBSL is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to qualify as a direct substitute:

• Resistance value: 2.49 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -65°C to +150°C
• Package configuration: Axial
• Physical dimensions: 0.090" Dia × 0.250" L
• Series compliance: MIL-PRF-39017/01, RLR07
• Features: Military Grade, Moisture Resistant, Weldable

The RLR07C2491FSB14 meets all substitution criteria as a parametric equivalent within the same military-grade RLR07 series.
