Substitute Part Grouping Explanation

Substitution eligibility for the CFF14JT680R is determined by strict equivalence across the following parameters:

• Resistance value: 680 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Package configuration: Axial through-hole
• Temperature coefficient: 0 / -400ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.091" Dia × 0.236" L
• Compliance: ROHS3 Compliant, REACH Unaffected

The CF14JT680R meets all electrical and mechanical equivalence criteria. The primary difference is packaging format: CFF14JT680R is supplied in Tape & Reel (TR) configuration, while CF14JT680R is supplied in Cut Tape (CT) configuration. Both parts share identical electrical performance and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both CFF14JT680R and CF14JT680R are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

CFF14JT680R in Tape & Reel format is suitable for high-volume automated assembly operations where tape-fed component handling is standard.

CF14JT680R in Cut Tape format is suitable for lower-volume applications, manual assembly, or situations where individual component handling is preferred.

Both parts deliver identical electrical performance and mechanical fit in circuit applications. The choice between them does not affect circuit functionality or reliability.

Frequently Asked Questions (FAQ)

Q: Can CF14JT680R be used as a direct replacement for CFF14JT680R?

A: Yes. Both parts are electrically and mechanically equivalent. The only difference is packaging format: CFF14JT680R uses Tape & Reel packaging while CF14JT680R uses Cut Tape packaging. Circuit performance is identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. They meet the same regulatory requirements.

Q: Does packaging format affect component performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical and mechanical specifications remain identical regardless of whether the part is supplied in Tape & Reel or Cut Tape format.

Q: What determines substitution eligibility for this resistor?

A: Substitution eligibility is determined by matching resistance value (680 Ohms), tolerance (±5%), power rating (0.25W), composition (Carbon Film), package type (Axial), temperature coefficient, operating temperature range, physical dimensions, and compliance certifications.

Q: Can parts with different packaging formats be mixed in the same assembly?

A: Yes. Since electrical and mechanical specifications are identical, parts with different packaging formats can be used interchangeably in the same circuit design. Packaging format selection should be based on assembly process requirements.
