Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-3P-2.54DSA(55) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (3)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A minimum)
• Voltage rating (250V minimum)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (UL94 V-0, RoHS Compliant)

The MDF7-3P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is the connector style designation (Board to Cable/Wire vs. Board to Board), which does not affect the physical mating interface or electrical performance for this application.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-3P-2.54DSA(95) is the appropriate substitute for the obsolete MDF7-3P-2.54DSA(55). Both parts maintain identical electrical specifications, mechanical dimensions, and material certifications. The MDF7-3P-2.54DSA(95) carries active product status with confirmed inventory availability, ensuring long-term procurement viability. Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability standards. The voltage rating specification difference (250V vs. 250VAC) does not constitute a functional limitation, as both ratings are equivalent for DC and AC applications within the stated parameters.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-3P-2.54DSA(95) be used as a direct replacement for the MDF7-3P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions, contact geometry, and material specifications. The MDF7-3P-2.54DSA(95) is active and available, making it the appropriate choice for new designs and ongoing production.

Q: What is the significance of the style designation difference (Board to Board vs. Board to Cable/Wire)?

A: The style designation reflects the intended application context but does not alter the physical mating interface, pin configuration, or electrical performance. Both headers are compatible with standard 2.54mm pitch receptacles.

Q: Are there any packaging differences between these parts?

A: The MDF7-3P-2.54DSA(55) packaging is unspecified in available documentation. The MDF7-3P-2.54DSA(95) is supplied in bag packaging. Packaging differences do not affect component functionality or performance.

Q: Do both parts meet the same compliance standards?
