Substitute Part Grouping Explanation

Substitution eligibility for the RNF14BAC3K74 is determined by strict equivalence across the following parameters:

• Resistance value: 3.74 kOhms
• Tolerance: ±0.1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: Axial
• Physical dimensions: 0.093" Dia x 0.250" L (2.35mm x 6.35mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

The RNF14BTC3K74 qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The only difference is packaging format: the main part is supplied in Tape & Box (TB) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both are manufactured by Stackpole Electronics Inc within the same RNF series.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14BAC3K74 and RNF14BTC3K74 are active production components manufactured by Stackpole Electronics Inc and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply chain availability:

• RNF14BAC3K74 (Tape & Box): Suitable for applications requiring boxed component packaging with tape reel format. Current inventory: 805 units.
• RNF14BTC3K74 (Cut Tape): Suitable for applications where cut tape packaging is acceptable. Current inventory: 4828 units.

Both parts are electrically and mechanically identical and can be used interchangeably in circuit designs without modification to PCB layouts or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTC3K74 be used as a direct replacement for RNF14BAC3K74?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Box). They have identical resistance values, tolerances, power ratings, temperature coefficients, and operating temperature ranges.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging includes a reel of components on tape with a protective box. Cut Tape packaging provides components on tape without the box. Both formats contain the same component specifications. The choice depends on assembly process requirements and storage preferences.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RNF14BAC3K74 and RNF14BTC3K74 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used in high-precision applications?

A: Yes. Both parts feature ±0.1% tolerance and ±50ppm/°C temperature coefficient, making them suitable for precision analog circuits, measurement equipment, and applications requiring tight tolerance specifications.

Q: What is the physical size of these resistors?

A: Both parts have identical axial dimensions of 0.093" diameter by 0.250" length (2.35mm x 6.35mm), compatible with standard through-hole PCB layouts.
