Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7B-9P-2.54DSA(01) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (9)
• Pitch specification (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Current rating (3A minimum)
• Voltage rating (250V minimum)
• Operating temperature range (-35°C ~ 85°C)
• Contact material and finish (Brass with Gold plating)
• Insulation material (Polybutylene Terephthalate)

The substitute part MDF7B-9P-2.54DSA(96) maintains all critical electrical and mechanical parameters required for direct substitution. Both parts belong to the MDF7 series and share identical pitch, position count, current capacity, and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The MDF7B-9P-2.54DSA(96) is a direct substitute for the obsolete MDF7B-9P-2.54DSA(01). Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts are RoHS Compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The minimal dimensional variance in overall contact length (0.01mm difference) is within standard manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MDF7B-9P-2.54DSA(96) directly replace MDF7B-9P-2.54DSA(01) in existing designs?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (9), current rating (3A), voltage rating (250V), contact geometry, and material specifications. The substitute part is functionally equivalent for all electrical and mechanical applications.

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

A: The suffix indicates different packaging or manufacturing batches within the same MDF7 series. The electrical and mechanical specifications remain identical between variants.

Q: Are there any dimensional differences between these parts?

A: Overall contact length differs by 0.01mm (0.867" versus 0.866"), which falls within standard manufacturing tolerances and does not impact PCB layout or mating compatibility.

Q: What is the packaging difference?

A: MDF7B-9P-2.54DSA(01) packaging is unspecified, while MDF7B-9P-2.54DSA(96) is supplied in Bag packaging. This affects logistics and storage but not component functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are RoHS Compliant with UL94 V-0 flammability rating and identical moisture sensitivity classification (MSL 1).

Q: What is the current availability status?

A: MDF7B-9P-2.54DSA(01) is classified as Obsolete with 1057 pieces in stock. MDF7B-9P-2.54DSA(96) is Active with 753 pieces in stock, providing ongoing supply assurance.
