Substitute Part Grouping Explanation
Substitution eligibility for the MDF7P-24DP-2.54DSA(55) is determined by strict equivalence across the following critical parameters:
- Connector type, contact type, and gender (Header, Male Pin)
- Number of positions and row configuration (24 positions, 2 rows)
- Pitch and row spacing (0.100" / 2.54mm)
- Mounting type and termination method (Through Hole, Solder)
- Electrical ratings (3A current, 250V voltage minimum)
- Operating temperature range (-35°C ~ 85°C minimum)
- Material compliance (UL94 V-0, RoHS Compliant)
The MDF7P-24DP-2.54DSA(95) qualifies as a direct substitute based on these parameters. Both parts share identical mechanical and electrical specifications within the MDF7 series from Hirose Electric Co Ltd.
