Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-15P-2.54DS(55) is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 15 positions
• Connector Type and Contact Configuration: Header with male pins
• Mounting Orientation: Through-hole, right-angle mounting
• Electrical Ratings: 3A current capacity and 250V voltage rating
• Insulation Material and Flammability: Polybutylene Terephthalate (PBT) with UL94 V-0 rating
• Contact Material and Finish: Brass with tin plating
• Termination Method: Solder termination

The MDF7-15P-2.54DS(95) qualifies as a direct substitute based on matching all critical parameters within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-15P-2.54DS(95) is the qualified substitute for the obsolete MDF7-15P-2.54DS(55). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the MDF7-15P-2.54DS(95) is currently in active production, ensuring availability and supply chain continuity.

Both parts carry RoHS compliance certification and identical moisture sensitivity ratings, supporting use in regulated and standard manufacturing environments. The UL94 V-0 flammability rating is maintained across both variants, preserving safety compliance requirements.

The contact length specifications show negligible variation (0.292" versus 0.293" for mating contact length), which falls within standard manufacturing tolerances and does not affect functional compatibility or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can MDF7-15P-2.54DS(95) be used as a direct replacement for MDF7-15P-2.54DS(55)?

A: Yes. Both parts share identical pitch (0.100"/2.54mm), position count (15), connector type (header), contact configuration (male pins), mounting method (through-hole right-angle), and electrical ratings (3A/250V). The substitute is functionally equivalent for all applications where the original part was specified.

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

A: The primary difference is product status. The MDF7-15P-2.54DS(55) is obsolete, while the MDF7-15P-2.54DS(95) is in active production. Minor variations in contact length specifications (0.292" versus 0.293") are within standard manufacturing tolerances and do not affect performance or compatibility.

Q: Are there packaging differences between these parts?

A: The MDF7-15P-2.54DS(55) packaging is not specified in available data. The MDF7-15P-2.54DS(95) is supplied in bag packaging. Packaging differences do not affect connector functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, and maintain identical moisture sensitivity levels (MSL 1 - Unlimited). Compliance certifications are equivalent across both variants.

Q: What is the voltage rating difference between 250V and 250VAC?

A: The MDF7-15P-2.54DS(55) specifies 250V, while the MDF7-15P-2.54DS(95) specifies 250VAC. Both ratings are compatible for standard connector applications. The AC specification on the substitute part is a clarification of the voltage type and does not represent a functional limitation.
