Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFC-145-32-LM-D-A is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (90)
• Number of rows (2)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Current rating (3.1A per Contact)
• Voltage rating (275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (ROHS3 Compliant, UL94 V-0)

The identified substitute part maintains identical specifications across all these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations
