Substitute Part Grouping Explanation

Substitution eligibility for the RN60D3161FBSL is determined by strict equivalence across the following critical parameters:

• Resistance Value: 3.16 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Operating Temperature Range: -65°C to 175°C (exact match required)
• Military Compliance: MIL-R-10509/1 series (exact match required)
• Physical Dimensions: 0.145" Dia x 0.344" L (exact match required)

The RN60C3161FB14 qualifies as a direct substitute based on full alignment with all critical parameters. Both parts belong to the Vishay Dale RN60 military resistor series and maintain identical electrical and mechanical specifications. The primary distinction between these parts is the temperature coefficient specification, which does not affect substitution eligibility within this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D3161FBSL and RN60C3161FB14 are active products manufactured by Vishay Dale within the military-grade RN60 series. Selection between these parts should be based on the following criteria:

RN60D3161FBSL is appropriate for applications where the specified temperature coefficient of ±100ppm/°C aligns with circuit design requirements and where existing inventory or procurement channels favor this variant.

RN60C3161FB14 is appropriate for applications requiring improved temperature stability, as indicated by its ±50ppm/°C temperature coefficient specification. This part offers enhanced performance in temperature-sensitive circuits while maintaining full compatibility with all other electrical and mechanical parameters.

Both parts comply with MIL-R-10509/1 military specification and carry identical RoHS non-compliant and REACH Affected regulatory status. Physical board layout and mechanical assembly considerations are identical due to matching axial package dimensions.
