Key Parameters

Substitute Part Grouping Explanation

The MDF7-22D-2.54DSA(96) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical connector type: Receptacle, bottom entry configuration
• Matching position count: 22 positions
• Identical pitch specification: 0.100" (2.54mm) mating pitch
• Identical row configuration: 2 rows with 0.100" (2.54mm) row spacing
• Matching contact specifications: Female socket, square contact shape, phosphor bronze material
• Identical electrical ratings: 3A current rating, 250VAC voltage rating
• Matching termination method: Solder through-hole
• Identical fastening type: Push-pull
• Matching contact finish: Gold-plated mating surface with tin-plated post
• Identical insulation material: Polyamide (PA), Nylon
• Matching environmental specifications: -35°C ~ 85°C operating temperature, UL94 V-0 flammability rating

The primary distinction is product status: the substitute part is active and currently in production, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-22D-2.54DSA(96) is the direct active equivalent for the obsolete MDF7-22D-2.54DSA(56). All electrical, mechanical, and environmental specifications are identical across both parts. The substitute part maintains active production status with Hirose Electric Co Ltd, ensuring long-term availability and supply chain continuity. Both parts carry identical compliance certifications including UL94 V-0 flammability rating and EAR99 export classification. The packaging difference (bulk for the substitute versus unspecified for the main part) does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the MDF7-22D-2.54DSA(56) and MDF7-22D-2.54DSA(96) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch specifications (0.100" / 2.54mm), mounting configuration (through-hole), and fastening type (push-pull). They are direct mechanical substitutes.

Q: Do these connectors have the same electrical ratings?

A: Yes. Both parts are rated for 3A current and 250VAC voltage with identical contact materials (phosphor bronze) and finishes (gold mating surface, tin post finish).

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The MDF7-22D-2.54DSA(56) is obsolete, while the MDF7-22D-2.54DSA(96) is active and in current production. Packaging is also specified as bulk for the active part. All technical specifications remain identical.

Q: Can I use the MDF7-22D-2.54DSA(96) in place of the MDF7-22D-2.54DSA(56) in existing designs?

A: Yes. The substitute part is fully compatible with applications designed for the obsolete part. No design modifications are required.

Q: Are there any environmental or compliance differences?

A: No. Both parts operate across -35°C to 85°C, carry UL94 V-0 flammability certification, and share identical moisture sensitivity level (MSL 1 - Unlimited) and export classifications (EAR99).

Q: What is the contact finish specification for both parts?

A: Both connectors feature gold-plated mating contacts (8.00µin / 0.203µm thickness) with tin-plated posts (39.4µin / 1.00µm thickness for the main part; unspecified for the substitute).
