Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF14JT390R are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 390 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Temperature coefficient: 0 / -400ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: Axial configuration
• Number of terminations: 2
• Compliance: ROHS3 Compliant

Packaging Variation Allowed: The primary difference among qualified substitutes is packaging format (Tape & Reel versus Cut Tape), which does not affect component functionality or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for 390 Ohms ±5% 0.25W carbon film resistors. Selection between these parts should be based on:

PCF14JT390R (Tape & Reel): Suitable for high-volume automated assembly processes requiring reel packaging.

CF14JT390R (Cut Tape): Suitable for mixed-volume production or manual assembly operations using cut tape format with identical physical dimensions to the main part.

CFM14JT390R (Cut Tape, Miniature): Suitable for space-constrained applications where the smaller physical footprint (0.067" Dia x 0.130" L) is advantageous, while maintaining all electrical specifications.

All parts are actively produced, ROHS3 compliant, and carry identical electrical performance characteristics within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CF14JT390R be used as a direct replacement for PCF14JT390R?

A: Yes. Both parts are electrically identical 390 Ohms ±5% 0.25W carbon film resistors with the same physical dimensions. The difference is packaging format: PCF14JT390R is supplied in Tape & Reel format, while CF14JT390R is supplied in Cut Tape format. Component functionality and performance are identical.

Q: What is the primary difference between CFM14JT390R and the other substitutes?

A: CFM14JT390R is a miniature variant with reduced physical dimensions (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L). All electrical parameters remain identical. This part is suitable for applications where board space is limited.

Q: Are all three parts ROHS3 compliant?

A: Yes. PCF14JT390R, CF14JT390R, and CFM14JT390R are all ROHS3 compliant with identical compliance status.

Q: Can packaging format be changed during production?

A: Yes. Packaging format (Tape & Reel versus Cut Tape) can be changed without affecting component electrical performance or mechanical compatibility in the circuit.

Q: What determines substitution eligibility for this resistor category?

A: Substitution eligibility is determined by matching resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, and package configuration. All three listed parts meet these criteria.
