Frequently Asked Questions (FAQ)

Q: Can MDF7C-25P-2.54DSA(73) be used as a direct replacement for MDF7C-25P-2.54DSA(33)?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (25), and base product family (MDF7C). The substitute maintains through-hole solder termination and male pin contact configuration required for board-level integration.

Q: What is the significance of the part number suffix difference (33 versus 73)?

A: The suffix designates internal Hirose configuration variants. The functional parameters—pitch, position count, connector type, and contact configuration—remain identical between these variants, establishing substitution equivalence.

Q: Are there packaging differences between these parts?

A: The MDF7C-25P-2.54DSA(33) packaging is not specified in available data. The MDF7C-25P-2.54DSA(73) is supplied in bag packaging. Confirm packaging requirements with procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Both parts are MSL Level 1 (Unlimited) and RoHS compliant. The original part carries ROHS3 designation while the substitute carries RoHS designation. Both satisfy environmental compliance requirements for standard applications.

Q: What electrical parameters should be verified for application compatibility?

A: Confirm that application requirements do not exceed 3A current rating and 250VAC voltage rating. Operating temperature range of -35°C to 85°C must accommodate the intended thermal environment.
