MDF7-16P-2.54DS(55) Equivalent & Substitute Parts

Part Overview

The MDF7-16P-2.54DS(55) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board applications with 16 positions at 0.100" (2.54mm) pitch. This part is classified as obsolete, making identification of active equivalent models essential for ongoing design support and procurement continuity. The substitute part MDF7-16P-2.54DS(95) provides functional equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution between MDF7-16P-2.54DS(55) and MDF7-16P-2.54DS(95) is based on the following critical parameters that remain constant across both parts:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 16
• Contact Type: Male Pin
• Connector Type: Header
• Mounting Type: Through Hole, Right Angle
• Current Rating: 3A
• Operating Temperature Range: -35°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: Yes
• Insulation Material: Polybutylene Terephthalate (PBT)
• Contact Material: Brass
• Termination: Solder

The primary difference between these parts is the application style designation (Board to Board vs. Board to Cable/Wire) and product status (Obsolete vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The MDF7-16P-2.54DS(95) is the active equivalent for the obsolete MDF7-16P-2.54DS(55). Both parts maintain identical electrical specifications (3A current rating, 250V voltage rating), thermal operating range (-35°C ~ 85°C), and mechanical pitch (0.100" / 2.54mm). Both are RoHS compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

For new designs or ongoing procurement, the MDF7-16P-2.54DS(95) is the appropriate selection due to its active product status and confirmed availability. The minor variation in contact length for mating (0.293" vs. 0.292") falls within normal manufacturing tolerance and does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can MDF7-16P-2.54DS(95) directly replace MDF7-16P-2.54DS(55)?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (16), contact type (male pin), current rating (3A), voltage rating (250V), and operating temperature range (-35°C ~ 85°C). The contact length variation (0.293" vs. 0.292") is within standard tolerance.

Q: What is the difference between "Board to Board" and "Board to Cable/Wire" designations?

A: These designations indicate the intended mating interface. The MDF7-16P-2.54DS(55) is specified for board-to-board connections, while the MDF7-16P-2.54DS(95) is specified for board-to-cable/wire connections. Both use identical header pin configurations and are mechanically compatible.

Q: Why is MDF7-16P-2.54DS(55) marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and product lifecycle management. The MDF7-16P-2.54DS(95) provides functional equivalence and is the active alternative for procurement.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and have MSL 1 moisture sensitivity classification. Electrical and thermal specifications are identical.

Q: What packaging is available for the substitute part?

A: The MDF7-16P-2.54DS(95) is supplied in bag packaging. The original part packaging specification was not provided.
