Key Parameters

Substitute Part Grouping Explanation

Substitution for the RN60D4751FRE6 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 4.75 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Number of terminations: 2

Allowable Variations:

• Packaging format (Cut Tape vs. Bulk)
• Temperature coefficient (±100ppm/°C to ±50ppm/°C)

The RN60D4751FRE6 in Cut Tape packaging is directly substitutable with RN60D4751FB14 in Bulk packaging. The RN60C4751FB14 represents an upgrade option with improved temperature coefficient performance (±50ppm/°C vs. ±100ppm/°C) while maintaining all other electrical and mechanical specifications.

Parameter Comparison
