Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JA12K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 12 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)
• Temperature coefficient: 0 / -500ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Regulatory compliance: RoHS3 Compliant (exact match required)

The substitute part CF14JA12K0 meets all electrical and mechanical criteria for direct substitution. Physical dimensions vary between the main part and substitute, reflecting different manufacturing series within the same product family. Both parts are manufactured by Stackpole Electronics Inc and maintain identical electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CFM14JA12K0 and CF14JA12K0 are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• PCB layout constraints: The CFM14JA12K0 features a smaller physical footprint (1.70mm diameter, 3.30mm length), suitable for space-constrained applications. The CF14JA12K0 has a larger footprint (2.30mm diameter, 6.00mm length).
• Inventory availability: CFM14JA12K0 currently has 1059 units in stock; CF14JA12K0 has 721 units in stock.
• Design flexibility: Both parts deliver identical electrical performance and regulatory compliance, allowing selection based on mechanical fit and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can CF14JA12K0 be used as a direct replacement for CFM14JA12K0?

A: Yes. Both parts are electrically equivalent with identical resistance (12 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), temperature coefficient, and operating range. The primary difference is physical dimension, which must be verified against PCB layout requirements.

Q: What is the difference in physical size between these parts?

A: CFM14JA12K0 measures 0.067" diameter × 0.130" length (1.70mm × 3.30mm). CF14JA12K0 measures 0.091" diameter × 0.236" length (2.30mm × 6.00mm). Both are axial through-hole packages.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CFM14JA12K0 and CF14JA12K0 are ROHS3 compliant and REACH unaffected.

Q: What determines substitution eligibility?

A: Substitution requires exact equivalence in resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, and regulatory compliance status. Physical dimensions may vary within the same product family.

Q: Which part should I select for a new design?

A: Selection depends on PCB layout constraints and available inventory. Verify that the physical dimensions of your chosen part fit your board layout. Both parts are active production items suitable for new designs.
