Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (121 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), axial package type, physical dimensions (0.180" Dia x 0.562" L), operating temperature range (-65°C to 175°C), and military series classification (MIL-R-10509/2, RN65 base product).

The identified substitutes maintain all electrical specifications and mechanical compatibility. Variations exist only in packaging format (tape and reel versus bulk) and temperature coefficient performance, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and are manufactured by Vishay Dale under the military MIL-R-10509/2 specification. Selection between RN65D1210FRE6, RN65D1210FB14, and RN65C1210FB14 is determined by packaging requirements and temperature stability needs.

RN65D1210FRE6 is specified when tape and reel packaging is required for automated assembly processes. RN65D1210FB14 provides equivalent electrical performance in bulk packaging format with identical temperature coefficient performance. RN65C1210FB14 offers enhanced temperature stability with a ±50ppm/°C coefficient compared to ±100ppm/°C in the other variants, suitable for applications requiring tighter long-term drift specifications, while maintaining bulk packaging format.

All parts comply with RoHS non-compliant status, REACH affected classification, and EAR99 export control designation. Selection should account for assembly methodology, inventory availability, and application temperature stability requirements.

Frequently Asked Questions (FAQ)

Q: Can RN65D1210FB14 replace RN65D1210FRE6 in production assemblies?

A: Yes. Both parts are electrically and mechanically identical with 121 Ohm resistance, ±1% tolerance, 0.5W power rating, and identical physical dimensions. The difference is packaging format: RN65D1210FRE6 is supplied in tape and reel format for automated pick-and-place assembly, while RN65D1210FB14 is supplied in bulk format. Selection depends on assembly process requirements.

Q: What is the difference between RN65D1210FB14 and RN65C1210FB14?

A: Both parts share identical electrical specifications and physical dimensions. The primary difference is temperature coefficient: RN65D1210FB14 has ±100ppm/°C while RN65C1210FB14 has ±50ppm/°C. RN65C1210FB14 provides superior temperature stability for applications requiring tighter long-term drift performance across the -65°C to 175°C operating range.

Q: Are all three parts suitable for military applications?

A: Yes. All three parts are manufactured under the military MIL-R-10509/2 specification and belong to the RN65 military series. Each part features flame retardant coating, moisture resistance, and safety-rated construction appropriate for high-reliability military and aerospace applications.

Q: Does packaging format affect electrical performance?

A: No. Tape and reel (RN65D1210FRE6) and bulk (RN65D1210FB14, RN65C1210FB14) packaging formats do not affect electrical characteristics. Packaging selection is based on assembly methodology and handling requirements only.

Q: Can these parts be used interchangeably in circuit designs?

A: Yes, with consideration for temperature coefficient requirements. RN65D1210FRE6 and RN65D1210FB14 are fully interchangeable. RN65C1210FB14 is interchangeable but offers improved temperature stability, making it suitable for applications where tighter resistance drift specifications are required across temperature extremes.
