Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC44K2 are qualified based on the following electrical and mechanical parameters:

• Resistance Value: Must be 44.2 kOhms
• Tolerance: Must be ±1%
• Composition: Must be metal film
• Package Type: Must be axial through-hole
• Temperature Coefficient: Must be ±50ppm/°C
• RoHS Compliance: Must maintain ROHS3 compliance

The substitute parts identified meet these core requirements. Variations in power rating (0.25W vs. 0.5W), physical dimensions, and maximum operating temperature represent design upgrades or alternative configurations that maintain functional equivalence while offering enhanced performance characteristics or improved availability.

Engineering Selection Recommendations

CMF5044K200FHEB (Manufacturer Recommended Substitute)

The CMF5044K200FHEB is the manufacturer-recommended equivalent from Vishay Dale. This part maintains identical electrical specifications (44.2 kOhms, ±1%, 0.25W) and axial package configuration as the RNF14FTC44K2. The CMF5044K200FHEB offers an extended operating temperature range (-55°C ~ 175°C) and includes moisture-resistant features. Both parts are ROHS3 compliant and available in Tape & Reel packaging. This substitute provides direct functional replacement with enhanced environmental performance.

CMF5544K200FHEB (Upgrade Substitute)

The CMF5544K200FHEB represents an upgraded configuration with doubled power rating (0.5W vs. 0.25W) while maintaining all other electrical parameters. This part is suitable for applications requiring higher power dissipation capability or thermal margin. The CMF5544K200FHEB is available in Cut Tape packaging and offers the same extended temperature range and moisture resistance as the CMF5044K200FHEB. Selection of this upgrade should be based on circuit power requirements and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can CMF5044K200FHEB be used as a direct replacement for RNF14FTC44K2?

A: Yes. Both parts share identical resistance (44.2 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), package type (axial), and temperature coefficient (±50ppm/°C). The CMF5044K200FHEB provides equivalent electrical performance with extended temperature range capability.

Q: What is the difference between CMF5044K200FHEB and CMF5544K200FHEB?

A: The primary difference is power rating. CMF5044K200FHEB is rated at 0.25W (1/4W), matching the original part. CMF5544K200FHEB is rated at 0.5W (1/2W), providing double the power dissipation capability. Both maintain identical resistance, tolerance, and temperature coefficient specifications. Physical dimensions also differ slightly due to the higher power rating.

Q: Are packaging format differences significant?

A: Packaging format differences (Tape & Reel vs. Cut Tape) affect procurement and assembly processes but do not impact electrical or mechanical compatibility. Selection should align with manufacturing equipment and supply chain requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. RNF14FTC44K2, CMF5044K200FHEB, and CMF5544K200FHEB are all ROHS3 compliant, meeting environmental and regulatory standards for electronic component manufacturing.

Q: What is the temperature coefficient significance?

A: All listed parts maintain ±50ppm/°C temperature coefficient, ensuring consistent resistance stability across operating temperature ranges. This parameter is critical for precision applications requiring predictable performance variation with temperature changes.
