Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JA27K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 27 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum required)
• Temperature coefficient: 0 / -500ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (minimum required)

The CF14JA27K0 meets all substitution criteria as a manufacturer-recommended equivalent from Stackpole Electronics Inc, maintaining identical electrical specifications and regulatory certifications while differing only in physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both CFM14JA27K0 and CF14JA27K0 are Active status products with identical electrical specifications and full regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection between these parts is based on physical space constraints and PCB layout requirements. The CFM14JA27K0 features a smaller form factor (1.70mm diameter x 3.30mm length), while the CF14JA27K0 has a larger form factor (2.30mm diameter x 6.00mm length). Both parts are suitable for applications requiring 27 kOhms resistance at 0.25W power dissipation across the -55°C to 155°C operating range. Inventory availability and lead time considerations may also influence part selection between these manufacturer-recommended equivalents.

Frequently Asked Questions (FAQ)

Q: Can CF14JA27K0 be used as a direct replacement for CFM14JA27K0?

A: Yes. Both parts are electrically identical with matching resistance (27 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), and regulatory compliance. The primary difference is physical dimension. Substitution is valid if PCB layout accommodates the larger form factor of CF14JA27K0 (2.30mm diameter x 6.00mm length versus 1.70mm diameter x 3.30mm length).

Q: What are the critical parameters that must match for substitution?

A: Substitution requires exact equivalence in resistance value (27 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), package type (axial), and temperature coefficient (0 / -500ppm/°C). Operating temperature range and regulatory compliance must meet or exceed the original specification.

Q: Are there any compatibility concerns with PCB assembly?

A: The CF14JA27K0 has larger physical dimensions than the CFM14JA27K0. Verify that PCB layout, component spacing, and automated assembly equipment can accommodate the larger form factor before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CFM14JA27K0 and CF14JA27K0 are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8533.10.0065) classifications.

Q: What is the temperature operating range for these resistors?

A: Both parts operate across -55°C to 155°C with a temperature coefficient of 0 / -500ppm/°C, ensuring stable resistance values across industrial and commercial temperature environments.
