RNC55H2001FSM23 Equivalent & Substitute Parts

Part Overview

The RNC55H2001FSM23 is a 2 kOhms ±1% 0.125W (1/8W) through-hole resistor with axial leads, manufactured by Vishay Dale. This military-grade metal film resistor features moisture resistance and weldability, meeting MIL-PRF-55182/01 specifications. The part is currently active in production with 606 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or procurement sourcing necessitate alternative components that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the RNC55H2001FSM23 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 175°C
• Physical dimensions: 0.094" Dia x 0.250" L
• Military series compliance: MIL-PRF-55182/01, RNC55 base product

The substitute part RNC55H2001FSB14 meets all these parameters identically, differing only in packaging configuration (FSB14 vs. FSM23 tape/reel designation) and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both RNC55H2001FSM23 and RNC55H2001FSB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging format requirements (FSM23 vs. FSB14 tape/reel configuration)
• Inventory availability and procurement lead times
• Supply chain sourcing preferences
• Both parts maintain RoHS non-compliant status and EAR99 export classification
• Both are subject to REACH regulations where applicable

No electrical performance difference exists between these components when applied to equivalent circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RNC55H2001FSB14 be used as a direct replacement for RNC55H2001FSM23?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The difference lies in packaging configuration (tape/reel designation). Direct substitution is valid for through-hole axial applications.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical physical dimensions of 0.094" diameter by 0.250" length (2.39mm x 6.35mm). They are mechanically interchangeable in PCB layouts.

Q: Do these parts have different temperature performance?

A: No. Both parts operate across the same temperature range (-65°C to 175°C) with identical temperature coefficient (±50ppm/°C).

Q: What determines substitution eligibility for RNC55 series resistors?

A: Substitution is valid when resistance value, tolerance, power rating, composition, package type, temperature specifications, and physical dimensions remain identical. The RNC55 base product number indicates military-grade metal film construction per MIL-PRF-55182/01.

Q: Are packaging differences significant for circuit design?

A: Packaging differences (FSM23 vs. FSB14) affect procurement and handling but do not impact electrical performance or PCB assembly compatibility for through-hole applications.
