Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNMF14FTD4K02 is determined by the following critical parameters:

• Resistance value: 4.02 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Compliance: RoHS3 compliant (exact match required)

The primary difference between the main part and its substitute lies in packaging format: the RNMF14FTD4K02 is supplied in Tape & Reel (TR) format, while the substitute RNF14FTD4K02 is supplied in Cut Tape (CT) format. Both parts are manufactured by Stackpole Electronics Inc and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNMF14FTD4K02 and RNF14FTD4K02 are Active status components manufactured by Stackpole Electronics Inc with identical electrical specifications and RoHS3 compliance. Selection between these parts should be based on packaging requirements and application assembly methodology. The Tape & Reel format of the RNMF14FTD4K02 is suitable for automated pick-and-place assembly operations, while the Cut Tape format of the RNF14FTD4K02 accommodates manual assembly or lower-volume production runs. Both parts meet the same regulatory and compliance standards.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD4K02 be used as a direct replacement for RNMF14FTD4K02?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The difference is packaging format: Tape & Reel versus Cut Tape. Verify that your assembly process accommodates the Cut Tape format before substitution.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated assembly equipment. Cut Tape packaging provides the same components on tape segments, suitable for manual handling or lower-volume assembly processes.

Q: Are there dimensional differences between these parts?

A: Yes. The RNMF14FTD4K02 measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm), while the RNF14FTD4K02 measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). Both are axial through-hole resistors, but the RNF14FTD4K02 has larger physical dimensions. Confirm PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNMF14FTD4K02 and RNF14FTD4K02 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: Which part should I select for high-volume automated assembly?

A: The RNMF14FTD4K02 in Tape & Reel format is designed for automated pick-and-place assembly operations typical of high-volume production.

Q: Which part should I select for manual assembly or prototyping?

A: The RNF14FTD4K02 in Cut Tape format is more practical for manual assembly, prototyping, or lower-volume applications.
