Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-30D-2.54DSA is determined by strict adherence to the following electrical and mechanical parameters:

• Connector type and form factor (Receptacle, Bottom Entry, Board to Board)
• Position count and row configuration (30 positions, 2 rows)
• Pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Mounting method (Through Hole, Solder termination)
• Fastening mechanism (Push-Pull)
• Electrical ratings (3A current, 250VAC voltage)
• Operating temperature range (-35°C ~ 85°C)
• Insulation material and flammability (Polyamide/Nylon, UL94 V-0)
• Contact material (Phosphor Bronze)
• Contact geometry (Square shape)

The MDF7-30D-2.54DSA(56) qualifies as a direct substitute based on identical compliance with all critical parameters listed above. The primary distinction between these parts is the contact finish specification on the mating interface.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-30D-2.54DSA(56) is the qualified substitute for the obsolete MDF7-30D-2.54DSA. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including position count, pitch, mounting configuration, current and voltage ratings, and operating temperature range.

The MDF7-30D-2.54DSA(56) offers the additional advantage of active product status and ROHS3 compliance, whereas the original part is obsolete and RoHS non-compliant. The contact finish difference (gold versus tin on the mating interface) does not affect functional compatibility, as both finishes meet the same electrical performance requirements within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are MDF7-30D-2.54DSA and MDF7-30D-2.54DSA(56) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including form factor, position count, pitch, row spacing, mounting type, and fastening mechanism. They are direct mechanical substitutes.

Q: What is the difference between the tin and gold contact finishes?

A: The mating contact finish differs between the two parts: tin on the MDF7-30D-2.54DSA and gold on the MDF7-30D-2.54DSA(56). Both finishes provide equivalent electrical performance within the specified operating parameters of 3A current and 250VAC voltage.

Q: Why is the original part listed as obsolete?

A: The MDF7-30D-2.54DSA is marked as obsolete by the manufacturer. The MDF7-30D-2.54DSA(56) is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: Does the RoHS compliance difference affect compatibility?

A: The RoHS compliance status reflects manufacturing and material standards but does not affect electrical or mechanical compatibility. The MDF7-30D-2.54DSA(56) meets ROHS3 requirements, making it suitable for applications with RoHS compliance mandates.

Q: Are there any packaging differences between these parts?

A: The MDF7-30D-2.54DSA(56) is supplied in bulk packaging, whereas packaging information for the original part is not specified in the available data.
