Key Parameters

Substitute Part Grouping Explanation

The substitute part MDF7B-3P-2.54DSA(96) is classified as a direct equivalent based on the following matching parameters:

• Identical manufacturer (Hirose Electric Co Ltd)
• Identical series designation (MDF7)
• Identical connector type (Header)
• Identical contact type (Male Pin)
• Identical number of positions (3)
• Identical pitch specification (0.100" / 2.54mm)
• Identical mounting type (Through Hole)
• Identical termination method (Solder)
• Identical current rating (3A)
• Identical voltage rating (250V)
• Identical operating temperature range (-35°C ~ 85°C)
• Identical material flammability rating (UL94 V-0)
• Identical RoHS compliance status

The primary distinction between the main part and substitute is product status: MDF7B-3P-2.54DSA(01) is obsolete, while MDF7B-3P-2.54DSA(96) maintains active product status with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

MDF7B-3P-2.54DSA(96) is the direct functional equivalent for MDF7B-3P-2.54DSA(01). The substitute part maintains identical electrical and mechanical specifications across all critical parameters. The transition from obsolete to active product status ensures continued component availability and manufacturing support.

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting the same regulatory and safety requirements. The overall contact length variance of 0.01mm (22.01mm versus 22.00mm) falls within standard manufacturing tolerances and does not affect functional compatibility.

Selection of MDF7B-3P-2.54DSA(96) is appropriate for new designs and replacement applications requiring the MDF7 series 3-position 2.54mm pitch header connector.

Frequently Asked Questions (FAQ)

Q: Are MDF7B-3P-2.54DSA(01) and MDF7B-3P-2.54DSA(96) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 3A current rating, 250V voltage rating, and identical contact materials and finishes. They are electrically interchangeable.

Q: What is the significance of the suffix designation (01) versus (96)?

A: The suffix designates the packaging configuration and manufacturing variant. MDF7B-3P-2.54DSA(01) is obsolete, while MDF7B-3P-2.54DSA(96) is the active equivalent with current manufacturing availability.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts feature identical mounting type (through hole), termination method (solder), pitch (2.54mm), and contact geometry. The 0.01mm difference in overall contact length is within standard manufacturing tolerance and does not affect mechanical fit or function.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and share identical moisture sensitivity level (MSL 1 - Unlimited). They meet identical regulatory and safety requirements.

Q: Can MDF7B-3P-2.54DSA(96) be used as a direct replacement in existing assemblies?

A: Yes. The substitute part is functionally and mechanically equivalent and can be used as a direct replacement in applications currently using MDF7B-3P-2.54DSA(01).
