Key Parameters

Substitute Part Grouping Explanation

The MDF7-18P-2.54DS(96) qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Series: Both parts belong to the MDF7 series header family
• Position Count & Pitch: Identical 18-position configuration at 0.100" (2.54mm) mating pitch
• Electrical Ratings: Matching 3A current rating and 250V voltage specification
• Mounting Configuration: Both feature through-hole, right-angle mounting
• Contact Material & Finish: Brass contacts with gold mating surface finish
• Insulation Material: Polybutylene Terephthalate (PBT) with UL94 V-0 rating
• Operating Temperature Range: Identical -35°C ~ 85°C specification
• Compliance: Both RoHS compliant with MSL 1 (Unlimited)

The primary distinction is application context: MDF7-18P-2.54DS(56) is configured for board-to-board connections, while MDF7-18P-2.54DS(96) is configured for board-to-cable/wire applications. Both maintain electrical and mechanical compatibility within the MDF7 connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-18P-2.54DS(96) is the appropriate selection for new designs and ongoing procurement due to its active product status. Both parts maintain identical electrical specifications (3A, 250V), thermal operating range (-35°C ~ 85°C), and compliance certifications (RoHS, UL94 V-0, MSL 1).

For applications currently using MDF7-18P-2.54DS(56), transition to MDF7-18P-2.54DS(96) is supported by matching contact geometry, pitch, and electrical ratings. The application context difference (board-to-board versus board-to-cable/wire) should be evaluated against specific mating interface requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can MDF7-18P-2.54DS(96) directly replace MDF7-18P-2.54DS(56) in existing assemblies?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical pitch (0.100"), position count (18), contact material (brass with gold finish), current rating (3A), and voltage rating (250V). The application context differs (board-to-board versus board-to-cable/wire), so verify that the mating interface in your assembly is compatible with the substitute part's intended application.

Q: What is the significance of the product status difference?

A: MDF7-18P-2.54DS(56) is classified as obsolete, indicating Hirose Electric has discontinued active production and support. MDF7-18P-2.54DS(96) maintains active status, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Are there packaging differences between these parts?

A: MDF7-18P-2.54DS(56) packaging is not specified in available data. MDF7-18P-2.54DS(96) is supplied in bag packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and have MSL 1 (Unlimited) moisture sensitivity level. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Q: What are the contact length specifications?

A: MDF7-18P-2.54DS(56) has mating contact length of 0.292" (7.42mm) and post length of 0.130" (3.30mm). MDF7-18P-2.54DS(96) has mating contact length of 0.293" (7.45mm) and post length of 0.130" (3.30mm). The mating contact length difference is 0.001" (0.03mm), which is within typical manufacturing tolerance.
