Key Parameters

Substitute Part Grouping Explanation

The RNF14BTC2K43 qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 2.43 kOhms (exact match)
• Tolerance: ±0.1% (exact match)
• Power rating: 0.25W, 1/4W (exact match)
• Composition: Metal Film (exact match)
• Package case: Axial (exact match)
• Temperature coefficient: ±50ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match)
• Physical dimensions: 0.093" Dia x 0.250" L (exact match)
• Compliance: ROHS3 Compliant (exact match)

The only difference between the main part and substitute is the packaging format: RNF14BAC2K43 is supplied in Tape & Box (TB) format, while RNF14BTC2K43 is supplied in Cut Tape (CT) format. Both formats contain identical components with no functional or performance variation.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14BAC2K43 and RNF14BTC2K43 maintain Active product status and are ROHS3 compliant. Selection between these parts should be based on packaging requirements and inventory availability. The RNF14BAC2K43 in Tape & Box format is suitable for applications requiring boxed component delivery, while the RNF14BTC2K43 in Cut Tape format accommodates automated assembly processes. With 3034 units of the Cut Tape variant in stock compared to 719 units of the Tape & Box variant, the RNF14BTC2K43 offers superior availability for high-volume production requirements. Both parts deliver identical electrical performance and mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTC2K43 replace RNF14BAC2K43 in my circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. RNF14BTC2K43 (Cut Tape) can directly replace RNF14BAC2K43 (Tape & Box) without any circuit modifications or performance impact.

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

A: Tape & Box (TB) format provides components on tape with a protective box for storage and manual handling. Cut Tape (CT) format provides components on tape without the box, optimized for automated pick-and-place assembly equipment. The components themselves are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Compliance status is equivalent.

Q: Which part should I select for automated assembly?

A: RNF14BTC2K43 in Cut Tape format is optimized for automated assembly processes. RNF14BAC2K43 in Tape & Box format is suitable for manual assembly or applications where boxed delivery is preferred.

Q: Is there a lead time difference between these parts?

A: RNF14BTC2K43 has higher inventory availability (3034 units) compared to RNF14BAC2K43 (719 units), which may result in shorter lead times for the Cut Tape variant.
