Parameter Comparison

Engineering Selection Recommendations

CF14JA750R (Original Part): Use when Tape & Box packaging is required and 1/4W power rating is specified for the application. This part maintains the original series designation and packaging format.

CFM12JT750R (Upgrade Option): Select this substitute when higher power dissipation capability is beneficial. The 1/2W rating provides increased thermal margin while maintaining identical electrical characteristics. Cut Tape packaging offers advantages for automated assembly processes. Significantly higher inventory availability (11519 units) supports supply chain continuity.

CFM14JT750R (Manufacturer Recommended): This option represents the manufacturer's current production standard for the 750 Ohm 1/4W specification. It maintains electrical equivalence with the original part while offering Cut Tape packaging. Adequate inventory (6089 units) supports standard procurement cycles.

All three parts are active products with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across applications.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT750R replace CF14JA750R in all applications? A: Yes, electrically and mechanically. The CFM12JT750R provides identical resistance, tolerance, and temperature characteristics. The higher 1/2W power rating is a superset capability that does not create incompatibility. Physical dimensions differ slightly but both are standard axial packages suitable for through-hole mounting.

Q: What is the difference between Tape & Box and Cut Tape packaging? A: Tape & Box (TB) provides resistors on tape with a protective box for storage and manual handling. Cut Tape (CT) supplies resistors on tape without the box, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging choice depends on assembly methodology.

Q: Are CFM series parts compatible with CF series applications? A: Yes. Both series are manufactured by Stackpole Electronics Inc and share identical electrical specifications for equivalent resistance values. The CFM designation indicates current production series while CF represents earlier production. Electrical and mechanical compatibility is maintained.

Q: Does the 1/2W rating of CFM12JT750R affect circuit design? A: No. Higher power rating does not alter electrical behavior. The component will operate identically to the 1/4W version in circuits designed for 1/4W resistors. The additional power capability simply provides thermal margin without changing voltage-current relationships.

Q: Are all three parts RoHS3 compliant? A: Yes. CF14JA750R, CFM12JT750R, and CFM14JT750R are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should be selected for new designs? A: CFM14JT750R is the manufacturer-recommended option for new designs, representing current production standards. It maintains 1/4W specification matching the original part while offering Cut Tape packaging benefits.
