Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C1001FRSL is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package: Axial
• Physical dimensions: 0.180" Dia x 0.562" L
• Termination count: 2
• Series compliance: Military, MIL-R-10509/2, RN65

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1%)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C)
• Packaging format: Tape & Reel (TR) or Bulk

The three identified substitutes (RN65C1001FB14, RN65C1001BB14, RN65E1001FB14) meet all mandatory matching parameters. Variations in tolerance and temperature coefficient represent improvements or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and are manufactured by Vishay Dale within the Military MIL-R-10509/2 RN65 series. Selection between substitutes depends on specific application requirements:

RN65C1001FB14 provides direct electrical equivalence with identical tolerance (±1%) and temperature coefficient (±50ppm/°C). The difference from the main part is packaging format (Bulk vs. Tape & Reel). This substitute is suitable for applications where packaging format does not impact assembly or procurement workflows.

RN65C1001BB14 offers improved tolerance specification (±0.1% vs. ±1%), maintaining the same temperature coefficient and operating range. This upgrade path is applicable when circuit designs require tighter resistance tolerance for precision applications.

RN65E1001FB14 provides equivalent tolerance (±1%) with improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C), resulting in better stability across the operating temperature range. This upgrade is suitable for temperature-sensitive applications requiring enhanced performance.

All parts comply with RoHS non-compliant status, REACH Affected designation, and identical ECCN/HTSUS classifications. Selection should be based on tolerance and temperature stability requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can RN65C1001FB14 be used as a direct replacement for RN65C1001FRSL?

A: Yes. Both parts share identical electrical specifications (1 kOhms ±1%, 0.5W, ±50ppm/°C) and mechanical dimensions (0.180" Dia x 0.562" L). The only difference is packaging format (Bulk vs. Tape & Reel). Functional performance in the circuit is equivalent.

Q: What is the difference between RN65C1001BB14 and the main part?

A: RN65C1001BB14 has tighter tolerance (±0.1% vs. ±1%) while maintaining all other specifications. This represents an upgrade for applications requiring higher precision resistance values.

Q: Why does RN65E1001FB14 have a different temperature coefficient?

A: RN65E1001FB14 features ±25ppm/°C temperature coefficient compared to ±50ppm/°C in the main part. This indicates superior thermal stability and is suitable for applications with stringent temperature performance requirements.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All parts are axial resistors with identical physical dimensions (0.180" Dia x 0.562" L) and two terminations, ensuring mechanical and electrical compatibility with the same PCB layout.

Q: What is the significance of packaging format differences?

A: The main part (RN65C1001FRSL) is supplied in Tape & Reel format for automated assembly. Substitute parts in Bulk format require manual handling or alternative assembly processes. Electrical and mechanical performance is unaffected by packaging format.

Q: Can these parts be used interchangeably in military applications?

A: All parts are certified to Military MIL-R-10509/2 RN65 series standards with identical compliance status. Interchangeability in military applications depends on specific design documentation and qualification requirements for the end system.
