Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-12DP-2.54DSA(55) is determined by strict equivalence across the following critical parameters:

• Number of Positions: 12
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3A
• Voltage Rating: 250V
• Operating Temperature Range: -35°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: Yes

The MDF7-12DP-2.54DSA(95) qualifies as a direct substitute based on complete alignment with these parameters. Variations in product status, packaging format, and style designation do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-12DP-2.54DSA(95) is the qualified substitute for the obsolete MDF7-12DP-2.54DSA(55). Selection is based on the following factors:

• Both parts maintain identical electrical specifications: 3A current rating, 250V voltage rating, and -35°C to 85°C operating temperature range
• Both parts comply with RoHS requirements and UL94 V-0 flammability standards
• Both parts utilize identical contact materials (brass) and insulation materials (PBT)
• The substitute part carries active product status, ensuring ongoing availability and manufacturing support
• The difference in style designation (Board to Board versus Board to Cable/Wire) reflects application context but does not affect connector pin configuration, pitch, or electrical performance
• Packaging format difference (unspecified versus bag) does not impact functional compatibility

Frequently Asked Questions (FAQ)

Q: Can MDF7-12DP-2.54DSA(95) be used as a direct replacement for MDF7-12DP-2.54DSA(55)?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters including position count, pitch, current rating, voltage rating, and operating temperature range. The substitute part is currently in active production status.

Q: What does the suffix difference between (55) and (95) indicate?

A: The suffix designates manufacturing or packaging variants within the MDF7 series. The electrical and mechanical specifications remain equivalent between these variants.

Q: Are there any compatibility concerns with the different style designations?

A: No. The style designation (Board to Board versus Board to Cable/Wire) describes the intended application context but does not affect the connector's physical dimensions, pin configuration, or electrical performance. Pin-to-pin compatibility is maintained.

Q: Does the packaging difference affect component selection?

A: No. Packaging format (bag versus unspecified) is a logistics consideration and does not impact electrical or mechanical compatibility. The connector itself remains functionally identical.

Q: Why is the original part marked as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The MDF7-12DP-2.54DSA(95) substitute provides continuity for designs requiring this connector configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both the original part and substitute meet RoHS compliance requirements and carry UL94 V-0 flammability certification.
