Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CF14JA3R00 are qualified based on the following criteria:

Electrical Equivalence: Resistance value (3 Ohms) and tolerance (±5%) must be identical. Temperature coefficient (±400ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed specifications.

Mechanical Compatibility: Package type must be Axial. Termination count must be 2. Physical dimensions must accommodate standard through-hole PCB mounting.

Composition & Features: Carbon film composition with flame retardant coating and safety features must be maintained.

Compliance: RoHS3 compliance and REACH unaffected status required for all substitutes.

Power Rating Consideration: The CF14JA3R00 operates at 0.25W. Substitute CFM12JT3R00 provides 0.5W rating (higher power capability), which is acceptable for applications requiring equal or lower power dissipation. Substitute CFM14JT3R00 maintains identical 0.25W rating.

Parameter Comparison

Engineering Selection Recommendations

CFM14JT3R00 (MFR Recommended Substitute): This part provides direct electrical and mechanical equivalence to the CF14JA3R00. Identical resistance, tolerance, power rating, and temperature characteristics ensure seamless substitution. Both parts maintain 0.25W rating and identical operating parameters. All compliance certifications (ROHS3, REACH unaffected) are satisfied. This substitute is preferred for direct replacement applications.

CFM12JT3R00 (Upgrade Substitute): This part provides identical electrical specifications with increased power rating (0.5W vs. 0.25W). The higher power capability allows operation in applications with greater power dissipation requirements while maintaining all other electrical and mechanical parameters. This substitute is suitable for applications where the original 0.25W rating may be marginal or where future design margin is required. All compliance requirements are met.

Both substitutes are Active status products with full inventory availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT3R00 replace CF14JA3R00 in all applications? A: Yes. CFM14JT3R00 provides identical electrical specifications (3 Ohms ±5%, 0.25W, ±400ppm/°C, -55°C ~ 155°C) and maintains axial package compatibility. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between CF14JA3R00 and CFM14JT3R00? A: Both parts are electrically and mechanically equivalent. The primary difference is the series designation (CF vs. CFM) and packaging format (Tape & Box vs. Cut Tape). Electrical performance and physical dimensions are identical.

Q: When should CFM12JT3R00 be used instead of CFM14JT3R00? A: CFM12JT3R00 provides 0.5W power rating compared to 0.25W in CFM14JT3R00. Use CFM12JT3R00 when circuit power dissipation exceeds 0.25W or when additional thermal margin is required. All other electrical parameters remain identical.

Q: Are physical dimensions compatible between all three parts? A: CF14JA3R00 and CFM14JT3R00 share identical axial dimensions (0.091" Dia x 0.130" L). CFM12JT3R00 has slightly larger dimensions (0.091" Dia x 0.256" L) due to higher power rating, but remains compatible with standard axial through-hole PCB layouts.

Q: Do all substitutes meet compliance requirements? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component applications.
