Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60C2491FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.49 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.145" Dia × 0.344" L (exact match required)
• Series: RN60 military grade (exact match required)

The RN60C2491FB14 qualifies as a direct substitute based on identical electrical performance and mechanical compatibility. The only difference is packaging format: RN60C2491FRE6 is supplied in Tape & Reel (TR) format, while RN60C2491FB14 is supplied in Bulk format. Both parts maintain the same base product number (RN60) and comply with MIL-R-10509/1 military specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RN60C2491FRE6 and RN60C2491FB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements:

RN60C2491FRE6 (Tape & Reel format) is suitable for automated assembly processes requiring component tape feeding and reel handling. This format optimizes high-volume production workflows.

RN60C2491FB14 (Bulk format) is suitable for manual assembly, kit assembly, or applications where individual component handling is required. This format provides flexibility for lower-volume or mixed-component applications.

Both parts maintain RoHS non-compliant status and REACH Affected classification. Both are subject to EAR99 export control classification. Selection should account for assembly methodology, production volume, and supply chain availability rather than electrical performance, as both parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can RN60C2491FB14 be used as a direct replacement for RN60C2491FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Direct substitution is valid from an electrical and mechanical standpoint. Assembly process compatibility must be verified based on your production equipment.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) format supplies components wound on continuous tape and mounted on reels, optimized for automated pick-and-place assembly equipment. Bulk format supplies loose components in containers, suitable for manual assembly or kit applications. Both formats contain identical components.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), and EAR99 export classification. Both comply with MIL-R-10509/1 military specifications.

Q: Can I mix these parts in the same assembly?

A: Yes, from an electrical and mechanical perspective. However, if your assembly process uses automated equipment designed for Tape & Reel format, manual insertion of Bulk components may introduce process inefficiencies or errors. Verify compatibility with your specific assembly workflow.

Q: What determines substitution eligibility for RN60 series resistors?

A: Substitution requires exact matching of resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, package type, physical dimensions, and military series classification. Packaging format (Tape & Reel versus Bulk) does not affect electrical or mechanical compatibility.
