Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC200R are grouped based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• RNMF14FTC200R: Identical electrical parameters (200Ω, ±1%, 0.25W) from the same manufacturer. Differs only in packaging format (Cut Tape vs. Tape & Reel) and physical dimensions (smaller Mini series form factor). Functionally interchangeable in circuit applications where board space permits the smaller package.

Upgraded Substitutes (Enhanced Specifications):

• CMF55200R00BHEB: Vishay Dale equivalent with improved tolerance (±0.1% vs. ±1%) and higher power rating (0.5W vs. 0.25W). Extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Adds moisture resistance feature.
• CMF55200R00FHEB: Vishay Dale equivalent with matching tolerance (±1%) and higher power rating (0.5W vs. 0.25W). Extended operating temperature range and moisture resistance. Same electrical tolerance as RNF14FTC200R.
• CMF50200R00FHEB: Vishay Dale equivalent with matching electrical specifications (200Ω, ±1%, 0.25W). Smaller form factor (CMF50 series) with extended operating temperature range (-55°C ~ 175°C) and moisture resistance.

All substitutes maintain the same resistance value (200 Ohms), metal film composition, axial package configuration, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): Select RNMF14FTC200R when the RNF14FTC200R is unavailable. Both parts are Active status, ROHS3 compliant, and electrically identical. The RNMF14FTC200R offers higher inventory availability (16022 pcs vs. 704 pcs) and is supplied in Cut Tape packaging. Physical dimensions differ (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L), requiring verification of board layout constraints.

For Enhanced Performance Applications: CMF55200R00FHEB provides equivalent electrical specifications to RNF14FTC200R with increased power dissipation capability (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C). Moisture resistance feature adds environmental protection. Select when thermal margin or humidity exposure is a design consideration.

CMF55200R00BHEB offers the tightest tolerance specification (±0.1%) among all substitutes, suitable for precision circuit applications requiring superior accuracy. Higher power rating and extended temperature range provide additional design margin.

CMF50200R00FHEB matches the RNF14FTC200R electrical specifications exactly while providing extended operating temperature range and moisture resistance in a compact form factor. Select for space-constrained designs where the smaller package (0.065" Dia x 0.150" L) is advantageous.

All substitute parts are Active status and ROHS3 compliant, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC200R replace RNF14FTC200R directly on the PCB? A: Electrically yes, but physical dimensions differ. RNMF14FTC200R is smaller (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L). Verify that the smaller package fits the existing PCB footprint and lead spacing before substitution.

Q: What is the difference between the Stackpole and Vishay Dale substitutes? A: Stackpole RNF and RNMF series are functionally equivalent to each other. Vishay Dale CMF series parts offer enhanced specifications: higher power ratings (0.5W options), extended operating temperature range (-55°C ~ 175°C), improved tolerance options (±0.1%), and moisture resistance. Select Vishay parts when these enhanced features are required by the application.

Q: Can I use CMF55200R00BHEB (0.5W) in place of RNF14FTC200R (0.25W)? A: Yes. The higher power rating (0.5W vs. 0.25W) is a superset capability. The part will operate safely in circuits designed for 0.25W resistors. Physical dimensions are comparable (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), allowing direct PCB substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF14FTC200R, RNMF14FTC200R, CMF55200R00BHEB, CMF55200R00FHEB, and CMF50200R00FHEB are all ROHS3 compliant, meeting regulatory requirements for restricted hazardous substances.

Q: Which substitute offers the best tolerance specification? A: CMF55200R00BHEB provides ±0.1% tolerance, the tightest specification among all parts listed. RNF14FTC200R, RNMF14FTC200R, CMF55200R00FHEB, and CMF50200R00FHEB all specify ±1% tolerance.

Q: What is the temperature coefficient difference between parts? A: All listed parts share identical temperature coefficient specifications of ±50ppm/°C, ensuring consistent performance across temperature variations.
