Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD3R00 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is packaging format compatibility. The RNF14FTD3R00 is supplied in Tape & Reel (TR) format, while the identified substitute RNF14FAD3R00 is supplied in Cut Tape (CT) format. Both parts maintain identical specifications across:

• Resistance value: 3 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.093" Dia x 0.250" L (2.35mm x 6.35mm)
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The only difference is the supply packaging format, which does not affect electrical performance or mechanical fit in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FTD3R00 and RNF14FAD3R00 are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain requirements and packaging format compatibility with assembly processes. The RNF14FTD3R00 in Tape & Reel format is suitable for automated pick-and-place assembly operations. The RNF14FAD3R00 in Cut Tape format accommodates manual assembly or alternative handling requirements. Both parts carry identical electrical performance characteristics and environmental ratings, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD3R00 be used as a direct replacement for RNF14FTD3R00?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Cut Tape. This difference does not affect circuit performance or component fit.

Q: What is the primary reason for substitution between these parts?

A: Packaging format availability and assembly process compatibility. If your production line requires Cut Tape format instead of Tape & Reel, or vice versa, the substitute part accommodates this requirement while maintaining all electrical specifications.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts measure 0.093" Dia x 0.250" L (2.35mm x 6.35mm) and use the same axial package configuration. They are mechanically interchangeable in circuit board layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF14FTD3R00 and RNF14FAD3R00 are ROHS3 compliant, REACH unaffected, and classified under EAR99. They carry identical environmental and regulatory certifications.

Q: What is the temperature operating range for these resistors?

A: Both parts operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring stable performance across industrial and commercial temperature ranges.

Q: Is there a difference in tolerance or resistance value between the two parts?

A: No. Both parts are 3 Ohm resistors with ±1% tolerance and 0.25W power rating. Electrical specifications are identical.
