Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D1251FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.25 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Series compliance: MIL-R-10509/1, RN60

The identified substitute part maintains identical electrical and mechanical specifications. The primary distinction between the main part and substitute is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Bulk packaging. Both parts are manufactured by Vishay Dale and carry the same military-grade certifications and environmental compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D1251FRE6 and RN60D1251FB14 are functionally equivalent and carry identical electrical specifications, military certifications, and environmental compliance designations. Selection between these parts should be based on packaging requirements and inventory availability.

The RN60D1251FRE6 in Tape & Reel format is suitable for automated assembly processes requiring continuous strip feeding. The RN60D1251FB14 in Bulk packaging is appropriate for manual assembly, kit builds, or applications where reel packaging is not required.

Both parts maintain active production status and are manufactured to MIL-R-10509/1 specifications. Neither part is RoHS compliant, and both are REACH Affected. Compliance requirements for your application must be verified against your regulatory obligations.

Frequently Asked Questions (FAQ)

Q: Can RN60D1251FB14 be used as a direct replacement for RN60D1251FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Bulk. Functional performance in the circuit is equivalent.

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

A: Tape & Reel (TR) packaging supplies components on a continuous carrier tape wound on a reel, designed for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in a container, suitable for manual assembly or small-quantity applications.

Q: Are these parts suitable for military applications?

A: Yes. Both parts are manufactured to MIL-R-10509/1 specifications and carry military-grade certifications including flame retardant coating and moisture resistance.

Q: What is the operating temperature range for these resistors?

A: Both parts operate from -65°C to 175°C with a temperature coefficient of ±100ppm/°C.

Q: Are these parts RoHS compliant?

A: No. Both RN60D1251FRE6 and RN60D1251FB14 are RoHS non-compliant. Verify compliance requirements for your application.

Q: What is the tolerance specification?

A: Both parts are rated at ±1% tolerance, suitable for precision circuit applications requiring tight resistance values.
