Substitute Part Grouping Explanation

Substitution eligibility for the HTST-120-01-L-DV-20 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Contact Type: Male Pin
• Shrouding: Shrouded - 4 Wall
• Current Rating: 3.4A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The HTST-120-01-L-DV-01 meets all substitution criteria as it maintains identical electrical and mechanical specifications across all critical parameters.
