Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JA75R0 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (75 Ohms), tolerance (±5%), and power rating (0.25W) must be identical
• Composition & Construction: Carbon film composition with flame retardant coating and safety features must be maintained
• Environmental Compliance: RoHS3 compliance and REACH unaffected status must be preserved
• Thermal Characteristics: Operating temperature range (-55°C to 155°C) and temperature coefficient (0 / -400ppm/°C) must match
• Package Configuration: Axial through-hole package with 2 terminations is required

The CF14JT75R0 meets all substitution criteria as a manufacturer-recommended equivalent, differing only in physical dimensions while maintaining full electrical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CFM14JA75R0 and CF14JT75R0 are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Physical Space Constraints: The CFM14JA75R0 features a smaller form factor (1.70mm diameter, 3.30mm length) compared to the CF14JT75R0 (2.30mm diameter, 6.00mm length). Applications with tight PCB layout requirements should specify the CFM14JA75R0.
• Availability & Lead Time: The CF14JT75R0 maintains significantly higher inventory (83990 units) compared to CFM14JA75R0 (3695 units), making it preferable for high-volume production or time-sensitive procurement.
• Electrical Equivalence: Both parts deliver identical electrical performance with 75 Ohm resistance, ±5% tolerance, 0.25W power rating, and matching thermal characteristics across the -55°C to 155°C operating range.
