Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following electrical and mechanical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Resistance value: 100 Ohms (exact match required)
• Composition: Metal Film (maintained across all substitutes)
• Package: Axial through-hole configuration
• Terminations: 2-pin axial leads
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Substitution Categories:

Direct Equivalent (Same Series, Different Packaging): RNMF14FTC100R maintains identical electrical specifications (100 Ohms ±1%, 0.25W, ±50ppm/°C) with the same manufacturer. Packaging differs only in tape format (Cut Tape vs. Tape & Reel), not electrical performance.

Upgraded Substitutes (Enhanced Specifications): CMF55100R00BEEB and CMF55100R00FHEB are Vishay Dale parts with improved power ratings (0.5W vs. 0.25W) and extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C). CMF55100R00BEEB offers tighter tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C).

Same-Specification Alternative (Different Manufacturer): CMF50100R00FHEB is a Vishay Dale equivalent with matching electrical specifications (100 Ohms ±1%, 0.25W, ±50ppm/°C) and identical operating temperature range. Physical dimensions are smaller (0.065" Dia x 0.150" L vs. 0.093" Dia x 0.250" L).

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (No Design Changes Required): RNMF14FTC100R and CMF50100R00FHEB are direct electrical equivalents to RNF14FTC100R. Both maintain 100 Ohms ±1% resistance, 0.25W power rating, and ±50ppm/°C temperature coefficient. RNMF14FTC100R is the manufacturer-recommended equivalent from Stackpole Electronics Inc. CMF50100R00FHEB offers the same electrical performance from Vishay Dale with a smaller physical footprint and extended operating temperature range to 175°C.

Upgraded Performance (Design Enhancement Possible): CMF55100R00FHEB provides identical tolerance and temperature coefficient to the main part while offering doubled power rating (0.5W) and extended temperature range (-55°C to 175°C). This part is suitable for applications requiring improved thermal margin or extended environmental operating conditions.

CMF55100R00BEEB offers the highest specification upgrade with ±0.1% tolerance and ±25ppm/°C temperature coefficient, along with 0.5W power rating and 175°C maximum operating temperature. This part is appropriate for precision applications requiring tighter tolerance and improved temperature stability.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC100R be used as a direct replacement for RNF14FTC100R? A: Yes. RNMF14FTC100R is the manufacturer-recommended equivalent from Stackpole Electronics Inc with identical electrical specifications (100 Ohms ±1%, 0.25W, ±50ppm/°C). The only difference is packaging format (Cut Tape vs. Tape & Reel) and physical size (smaller Mini series). Electrical performance is equivalent.

Q: What is the difference between the Stackpole and Vishay Dale substitutes? A: Stackpole RNMF14FTC100R maintains identical electrical specifications with different packaging. Vishay Dale parts (CMF series) offer enhanced specifications: CMF50100R00FHEB matches electrical performance with extended temperature range; CMF55100R00FHEB doubles power rating to 0.5W; CMF55100R00BEEB provides tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C).

Q: Can I use a 0.5W rated resistor in place of a 0.25W rated resistor? A: Yes, from a power dissipation perspective. CMF55100R00FHEB and CMF55100R00BEEB have 0.5W ratings, providing additional thermal margin. However, verify that physical size changes (0.090" x 0.240" vs. 0.093" x 0.250") do not conflict with PCB layout constraints.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with RNF14FTC100R.

Q: What is the impact of different temperature coefficients? A: RNF14FTC100R and most substitutes have ±50ppm/°C temperature coefficient. CMF55100R00BEEB has ±25ppm/°C, providing improved resistance stability across temperature variations. This is beneficial for precision applications but not required for general-purpose use.

Q: Does physical size matter when selecting a substitute? A: Yes. RNMF14FTC100R is smaller (0.070" x 0.130") than the original. CMF50100R00FHEB is also smaller (0.065" x 0.150"). CMF55100R00BEEB and CMF55100R00FHEB are similar in size (0.090" x 0.240"). Verify PCB layout compatibility before substitution.
