Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC115K is determined by the following critical parameters:

• Resistance value: 115 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CMF55115K00FHEB from Vishay Dale meets all substitution criteria with identical electrical specifications and axial package configuration. Differences in physical dimensions and packaging format (Cut Tape vs. Tape & Reel) do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The CMF55115K00FHEB is a direct functional equivalent to the RNF12FTC115K. Both components are Active status products with ROHS3 compliance and REACH unaffected certification, meeting current regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on:

• Packaging format availability: RNF12FTC115K supplied in Tape & Reel format; CMF55115K00FHEB supplied in Cut Tape format
• Operating temperature margin: CMF55115K00FHEB extends upper operating limit to 175°C versus 155°C for RNF12FTC115K
• Inventory availability: CMF55115K00FHEB currently has higher stock levels (1881 units vs. 684 units)
• Moisture resistance: CMF55115K00FHEB includes moisture resistant feature in addition to flame retardant coating

Frequently Asked Questions (FAQ)

Q: Can CMF55115K00FHEB replace RNF12FTC115K in existing circuit designs?

A: Yes. Both components share identical electrical specifications (115 kOhms ±1%, 0.5W, ±50ppm/°C) and axial package configuration. Functional compatibility is maintained across all standard circuit applications.

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

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape supplies components on tape segments cut to specified lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components with no functional difference.

Q: Does the extended operating temperature range of CMF55115K00FHEB affect compatibility?

A: No. The CMF55115K00FHEB operating range of -55°C to 175°C encompasses the RNF12FTC115K range of -55°C to 155°C. The substitute part maintains performance across the original part's full operating window and extends capability to higher temperatures.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF12FTC115K and CMF55115K00FHEB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does the moisture resistant feature on CMF55115K00FHEB provide?

A: Moisture resistant construction reduces susceptibility to humidity-related performance degradation in high-humidity environments. This feature is additional to the flame retardant coating present on both components.
