Substitute Part Grouping Explanation
Substitution of the MDF7-3P-2.54DSA(01) is based on electrical and mechanical parameter equivalence within the MDF7 series. The substitute part MDF7-3P-2.54DSA(96) maintains identical specifications across all critical parameters that determine functional compatibility:
- Connector type, contact type, and pin configuration (3-position, 1-row, male pins)
- Pitch and mating dimensions (0.100" / 2.54mm)
- Electrical ratings (3A, 250V)
- Material composition and contact finish (brass with gold plating)
- Thermal operating range (-35°C to 85°C)
- Compliance certifications (UL94 V-0, RoHS Compliant)
The primary distinction between these parts is product status and packaging format. The substitute part carries active product status with bag packaging, whereas the original part is obsolete.
