Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for CF14JA1M80 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.8 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 to 155°C (exact match required)
• Compliance certifications: RoHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part CFM14JA1M80 meets all electrical and mechanical equivalence criteria. The primary distinction between the main part and substitute relates to packaging format (Tape & Box versus Cut Tape) and physical dimensions, which do not affect electrical performance or circuit-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CF14JA1M80 and CFM14JA1M80 are Active status products with identical electrical specifications and full regulatory compliance (RoHS3 Compliant, REACH Unaffected). Selection between these parts should be based on procurement requirements and assembly process compatibility:

CF14JA1M80 is supplied in Tape & Box packaging format, suitable for applications requiring bulk quantities with standard storage and handling procedures.

CFM14JA1M80 is supplied in Cut Tape format, appropriate for automated pick-and-place assembly operations and applications with moderate volume requirements.

Both parts deliver equivalent electrical performance and thermal stability across the specified operating temperature range of -55°C to 155°C. Physical dimension differences do not impact circuit-level functionality or PCB layout compatibility for standard axial resistor footprints.

Frequently Asked Questions (FAQ)

Q: Can CFM14JA1M80 be used as a direct replacement for CF14JA1M80 in production?

A: Yes. Both parts are electrically identical with matching resistance value (1.8 MOhms), tolerance (±5%), power rating (0.25W), and operating specifications. The difference is packaging format only. Verify that your assembly process accommodates the Cut Tape format if switching from Tape & Box.

Q: What is the primary difference between CF14JA1M80 and CFM14JA1M80?

A: The main difference is packaging format and physical dimensions. CF14JA1M80 uses Tape & Box packaging with larger dimensions (0.091" Dia x 0.236" L), while CFM14JA1M80 uses Cut Tape packaging with smaller dimensions (0.067" Dia x 0.130" L). Electrical performance is identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CF14JA1M80 and CFM14JA1M80 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts have a temperature coefficient of 0 / -1500ppm/°C, ensuring stable resistance values across the operating temperature range of -55°C to 155°C.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from an electrical standpoint. However, physical dimension differences may affect PCB layout and component placement. Verify that your PCB footprint and assembly equipment accommodate the specific part dimensions before substitution.
