Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JA1M20 is determined by strict equivalence in the following electrical and mechanical parameters:

• Resistance Value: 1.2 MOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package Configuration: Axial leads (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CF14JA1M20 qualifies as a direct substitute based on identical electrical specifications and axial package compatibility. Packaging format differences (Cut Tape vs. Tape & Box) do not affect electrical or mechanical performance and represent supply chain variants only.

Parameter Comparison

Engineering Selection Recommendations

The CF14JA1M20 is a direct electrical and mechanical equivalent to the CFM14JA1M20. Both parts maintain identical resistance, tolerance, power rating, and operating specifications. The primary distinction is packaging format: CFM14JA1M20 is supplied in Cut Tape format, while CF14JA1M20 is supplied in Tape & Box format. This packaging difference does not affect component performance or circuit compatibility.

Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. Selection between these parts should be based on packaging requirements and inventory availability rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can CF14JA1M20 be used as a direct replacement for CFM14JA1M20 in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Box), which does not affect circuit performance or component functionality.

Q: Are there any dimensional differences between these parts?

A: The parts have different physical dimensions. CFM14JA1M20 measures 0.067" Dia x 0.130" L (1.70mm x 3.30mm), while CF14JA1M20 measures 0.091" Dia x 0.236" L (2.30mm x 6.00mm). Despite these dimensional variations, both are axial-lead resistors with identical electrical specifications and are mechanically compatible in standard through-hole applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CFM14JA1M20 and CF14JA1M20 are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements.

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

A: Cut Tape (CT) packaging provides individual component strips cut to length, while Tape & Box (TB) packaging includes the same tape format supplied in a protective box. Both formats contain the same components with identical specifications. Packaging selection depends on assembly process requirements and inventory management preferences.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. The electrical and mechanical specifications are identical, making them fully interchangeable for circuit design purposes. Packaging format does not affect circuit performance or compatibility.
