Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JT30R0 is determined by strict equivalence across the following critical parameters:

• Electrical Equivalence: Resistance value (30 Ohms), tolerance (±5%), and power rating (0.25W) must be identical
• Material Composition: Carbon film construction ensures consistent electrical behavior and thermal characteristics
• Package Compatibility: Axial through-hole package with 2 terminations maintains PCB layout and assembly compatibility
• Environmental Performance: Operating temperature range (-55°C to +155°C) and temperature coefficient (0 / -400 ppm/°C) must support the application environment
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status ensure regulatory alignment

The CF14JT30R0 meets all substitution criteria as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The CF14JT30R0 is a direct electrical and functional equivalent to the CFM14JT30R0. Both parts are manufactured by Stackpole Electronics Inc and share identical electrical specifications, material composition, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The primary difference is physical dimension: the CF14JT30R0 has a larger axial body (0.091" Dia x 0.236" L versus 0.067" Dia x 0.130" L). This dimensional variance does not affect electrical performance but may impact PCB layout considerations in space-constrained applications. Both parts maintain the same 2-termination axial configuration suitable for standard through-hole assembly.

Selection between CFM14JT30R0 and CF14JT30R0 should be based on available inventory, lead time requirements, and PCB layout constraints. Both parts satisfy identical electrical and compliance requirements.
