Key Parameters

Substitute Part Grouping Explanation

Substitution of the RNF14FAC200R is determined by the following critical parameters: resistance value (200 Ohms), tolerance (±1%), power rating (0.25W minimum), composition (metal film), package type (axial), and compliance certifications (ROHS3). Substitute parts must maintain electrical equivalence across these parameters while accommodating variations in physical dimensions, packaging format, and manufacturer specifications.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical Specifications): RNMF14FTC200R and CMF50200R00FHEB maintain identical electrical characteristics to the main part, differing only in physical size and packaging format.

Upgraded Equivalents (Enhanced Specifications): CMF55200R00BHEB and CMF55200R00FHEB provide higher power ratings (0.5W) and extended operating temperature ranges (-55°C to 175°C), offering design margin improvements while maintaining the required 200 Ohms resistance and meeting tolerance and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance, ensuring regulatory alignment and supply chain reliability. Selection between direct equivalents and upgraded equivalents depends on application requirements:

RNMF14FTC200R is recommended for direct replacement when physical space constraints favor a smaller form factor (0.070" diameter vs. 0.093" diameter) while maintaining identical electrical performance and operating temperature range.

CMF50200R00FHEB provides direct electrical equivalence with enhanced moisture resistance and extended operating temperature capability (-55°C to 175°C) in a compact 0.065" diameter package, suitable for applications requiring improved environmental protection.

CMF55200R00FHEB offers increased power dissipation capacity (0.5W vs. 0.25W) with ±1% tolerance and extended temperature range, appropriate for designs requiring thermal margin or operation at elevated ambient temperatures.

CMF55200R00BHEB provides the highest tolerance specification (±0.1%) with 0.5W power rating and extended temperature range, suitable for precision applications where tighter resistance tolerance is required.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC200R be used as a direct replacement for RNF14FAC200R?

A: Yes. Both parts share identical electrical specifications: 200 Ohms ±1% resistance, 0.25W power rating, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is physical size; RNMF14FTC200R is a miniature variant with smaller diameter (0.070" vs. 0.093"). Verify PCB layout compatibility before substitution.

Q: What is the advantage of CMF55200R00BHEB over the main part?

A: CMF55200R00BHEB provides three enhancements: doubled power rating (0.5W vs. 0.25W), tighter tolerance (±0.1% vs. ±1%), and extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C). These upgrades provide design margin for thermal stress and precision requirements.

Q: Are all substitute parts moisture resistant?

A: The main part RNF14FAC200R specifies flame retardant coating and safety features. All Vishay Dale substitute parts (CMF series) add moisture resistance to their feature set. Stackpole RNMF14FTC200R maintains the same feature specification as the main part.

Q: Can I use a 0.5W rated resistor in place of a 0.25W specification?

A: Yes, provided the circuit design accommodates the larger physical dimensions. Higher power-rated resistors are electrically compatible with lower power applications and provide additional thermal margin. Verify PCB footprint and thermal environment compatibility.

Q: Do all parts meet the same compliance standards?

A: All listed parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements. All parts carry EAR99 ECCN classification and 8533.21.0090 HTSUS code.
