Substitute Part Grouping Explanation

Substitute parts for the 641126-2 rectangular connector header are identified based on strict electrical and mechanical parameter equivalence within the MTA-100 series. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (2)
• Pitch spacing (0.100" / 2.54mm)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Parameters:

• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)
• Contact finish specifications (Gold mating, Tin post)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• RoHS compliance status

Parts meeting all these criteria are classified as direct substitutes. The 3-641126-2 is identified as a substitute part within the same series, maintaining identical electrical and mechanical specifications while differing in product status and packaging configuration.
