Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC12K7 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 12.7 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variations:

• Power rating: Equal or higher than 0.25W
• Operating temperature range: Equal or higher upper limit
• Physical dimensions: Minor variations acceptable within axial package specifications
• Packaging format: Tape & Reel or Cut Tape formats are interchangeable for component selection

The CMF5512K700FHEB qualifies as a direct substitute because it maintains all critical electrical parameters while offering an upgraded power rating (0.5W vs 0.25W) and extended maximum operating temperature (175°C vs 155°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RNF14FTC12K7): Select the RNF14FTC12K7 when the application requires a 0.25W power rating and operating temperatures do not exceed 155°C. This part is actively produced and maintains full ROHS3 and REACH compliance.

Substitute Part Selection (CMF5512K700FHEB): Select the CMF5512K700FHEB when higher power dissipation capacity is required (0.5W rating) or when operating temperatures may reach up to 175°C. This substitute maintains identical electrical specifications while providing enhanced thermal performance and moisture resistance. Both parts carry equivalent compliance certifications.

Both parts are active production components with established supply availability and meet all regulatory requirements for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can CMF5512K700FHEB replace RNF14FTC12K7 in all applications?

A: Yes, the CMF5512K700FHEB is electrically and mechanically compatible. The higher power rating (0.5W vs 0.25W) and extended temperature range (175°C vs 155°C) make it suitable for all applications where the RNF14FTC12K7 is specified, provided circuit board layout accommodates the slightly different physical dimensions.

Q: What are the physical dimension differences?

A: RNF14FTC12K7 measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF5512K700FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial package format with 2 terminations and fit standard through-hole PCB layouts.

Q: Are packaging formats interchangeable?

A: RNF14FTC12K7 is supplied in Tape & Reel format while CMF5512K700FHEB is supplied in Cut Tape format. Both formats contain identical components; the difference is in handling and storage packaging only. Component selection is not affected by packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF14FTC12K7 and CMF5512K700FHEB are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8533.21.0090).

Q: What is the temperature coefficient significance?

A: Both parts share an identical temperature coefficient of ±50ppm/°C, meaning resistance value stability across temperature variations is equivalent. This parameter is critical for precision applications and remains unchanged between the main part and substitute.
