Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C4641FMB14 is determined by strict equivalence across the following parameters:

• Resistance value: 4.64 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.250" L
• Termination count: 2
• Military series compliance: MIL-PRF-39017/01, RLR07 base product

The RLR07C4641FSB14 meets all these criteria and qualifies as a direct substitute. Differences in failure rate classification do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C4641FMB14 and RLR07C4641FSB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on failure rate requirements for the application.
