RN60C4751FRE6 Equivalent & Substitute Parts

Part Overview

The RN60C4751FRE6 is a 4.75 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. This component is manufactured by Vishay Dale and complies with military specification MIL-R-10509/1. The resistor features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part is currently active in production with 646 units available in tape and reel packaging.

Substitute parts are necessary when tape and reel packaging is unavailable or when bulk packaging better suits procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

The RN60C4751FB14 qualifies as a direct substitute for the RN60C4751FRE6 based on the following criteria:

• Identical resistance value: 4.75 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -65°C to 175°C
• Identical military series designation: MIL-R-10509/1, RN60
• Identical physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Identical features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The only difference between these parts is packaging format: RN60C4751FRE6 is supplied in tape and reel (TR), while RN60C4751FB14 is supplied in bulk. Both parts are manufactured by Vishay Dale and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both RN60C4751FRE6 and RN60C4751FB14 are active production components manufactured by Vishay Dale under the military specification MIL-R-10509/1. Selection between these parts should be based on packaging requirements:

• Select RN60C4751FRE6 when tape and reel packaging is required for automated assembly processes.
• Select RN60C4751FB14 when bulk packaging is acceptable or preferred for manual assembly or when higher inventory availability is needed.

Both parts maintain identical electrical performance, mechanical compatibility, and compliance status. The RoHS non-compliant and REACH Affected designations apply equally to both variants.

Frequently Asked Questions (FAQ)

Q: Can RN60C4751FB14 be used as a direct replacement for RN60C4751FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus tape and reel). All electrical parameters, physical dimensions, temperature characteristics, and military specifications are identical.

Q: What is the difference between tape and reel and bulk packaging?

A: Tape and reel packaging (TR) is designed for automated pick-and-place assembly equipment. Bulk packaging contains loose components suitable for manual assembly or alternative handling methods. The components themselves are identical.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No compatibility issues exist. Both parts are axial through-hole resistors with identical lead spacing, diameter, and length. They are mechanically and electrically interchangeable in all applications.

Q: Do both parts meet the same military specifications?

A: Yes. Both RN60C4751FRE6 and RN60C4751FB14 are manufactured to MIL-R-10509/1 specification and carry identical military series designation (RN60).

Q: What is the significance of the RoHS non-compliant status?

A: Both parts are designated as RoHS non-compliant. This status applies equally to both variants and should be considered during component selection for applications with RoHS compliance requirements.
