Key Parameters

Substitute Part Grouping Explanation

The RN60C4993FB14 is classified as a parametric equivalent to the RN60C4993FBSL. Substitution is valid based on the following criteria:

• Identical resistance value: 499 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -65°C to 175°C
• Identical package type: Axial
• Identical physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Identical series designation: Military, MIL-R-10509/1, RN60
• Identical feature set: Flame Retardant Coating, Military, Moisture Resistant, Safety

Both parts belong to the same RN60 base product family and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60C4993FBSL and RN60C4993FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications.
