Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCF14JT51K0 is determined by matching the following critical parameters:

• Resistance value: 51 kOhms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Temperature coefficient: 0 / -500ppm/°C
• Operating temperature range: -55°C to 155°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute parts maintain identical electrical specifications and regulatory status. Variations occur in packaging format (Tape & Reel versus Cut Tape) and physical dimensions, which do not affect electrical performance but may impact assembly and procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF14JT51K0, CF14JT51K0, and CFM14JT51K0—are Active products from Stackpole Electronics Inc with full ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on packaging and dimensional requirements:

CF14JT51K0 is functionally equivalent to PCF14JT51K0 with identical electrical specifications and physical dimensions, differing only in packaging format (Cut Tape versus Tape & Reel).

CFM14JT51K0 maintains all electrical specifications but features reduced physical dimensions (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L). This compact variant is suitable for space-constrained applications while preserving electrical performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CF14JT51K0 replace PCF14JT51K0 in production?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The difference is packaging format: PCF14JT51K0 is supplied in Tape & Reel while CF14JT51K0 is supplied in Cut Tape. Assembly compatibility depends on your equipment configuration.

Q: What are the physical dimension differences between CFM14JT51K0 and the other variants?

A: CFM14JT51K0 has reduced dimensions of 0.067" Dia x 0.130" L compared to 0.091" Dia x 0.236" L for PCF14JT51K0 and CF14JT51K0. This affects board layout and mechanical fit but does not impact electrical performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. PCF14JT51K0, CF14JT51K0, and CFM14JT51K0 are all ROHS3 Compliant and REACH Unaffected.

Q: Which part should I select for new designs?

A: Selection is based on packaging and dimensional requirements. For Tape & Reel supply, use PCF14JT51K0. For Cut Tape supply with standard dimensions, use CF14JT51K0. For space-constrained applications requiring compact dimensions, use CFM14JT51K0. All three deliver identical electrical performance.

Q: Can CFM14JT51K0 be used as a direct mechanical replacement?

A: CFM14JT51K0 is electrically equivalent but has different physical dimensions. Mechanical compatibility depends on your PCB layout and component spacing. Verify board design accommodates the reduced size before substitution.
