Key Parameters

Substitute Part Grouping Explanation

The PCF14JT680R qualifies as a direct substitute for the CF14JA680R based on the following matching electrical and mechanical parameters:

• Identical resistance value: 680 Ohms
• Identical tolerance: ±5%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Carbon Film
• Identical operating temperature range: -55°C to 155°C
• Identical temperature coefficient: 0 / -400ppm/°C
• Identical physical dimensions: 0.091" Dia x 0.236" L (2.30mm x 6.00mm)
• Identical number of terminations: 2
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is packaging format: CF14JA680R is supplied in Tape & Box (TB) format, while PCF14JT680R is supplied in Cut Tape (CT) format with radial bend capability. Both maintain identical electrical performance and mechanical compatibility for through-hole axial mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both CF14JA680R and PCF14JT680R are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The CF14JA680R in Tape & Box format is suitable for standard component kits and manual assembly workflows. The PCF14JT680R in Cut Tape format with radial bend capability offers flexibility for automated pick-and-place assembly systems and applications requiring component lead bending prior to insertion. Both parts deliver identical electrical performance and thermal characteristics across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can PCF14JT680R replace CF14JA680R in existing circuit designs?

A: Yes. Both parts share identical electrical specifications (680 Ohms, ±5%, 0.25W), composition (carbon film), temperature characteristics, and physical dimensions. The substitution is electrically and mechanically compatible for all through-hole axial mounting applications.

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

A: Tape & Box (TB) packaging supplies components on tape with a protective box, suitable for manual assembly and component storage. Cut Tape (CT) packaging provides components on tape without the box, optimized for automated assembly equipment. Both formats contain identical components.

Q: Does the radial bend feature of PCF14JT680R affect circuit performance?

A: No. The radial bend capability is a mechanical feature that allows lead bending for assembly purposes. It does not alter electrical performance, resistance value, tolerance, power rating, or thermal characteristics. The component functions identically to the standard axial configuration.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both CF14JA680R and PCF14JT680R operate across the identical temperature range of -55°C to 155°C with the same temperature coefficient (0 / -400ppm/°C), ensuring stable performance in industrial and commercial temperature environments.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
