DF1E-7P-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1E-7P-2.5DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 7-position connector operates at 0.098" (2.50mm) pitch with a 3A current rating and operates across -35°C to 85°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the DF1E-7P-2.5DS is constrained by the following critical parameters:

Primary Constraint: Pitch mating of 0.098" (2.50mm) is unique to the Hirose DF1E series. All substitute parts operate at 0.100" (2.54mm) pitch, representing a 0.002" (0.04mm) difference. This pitch variance requires mechanical accommodation in the mating connector or cable assembly.

Maintained Parameters Across Substitutes:

7-position configuration
Male pin contact type
Through-hole, right-angle mounting
Shrouded 4-wall design
Solder termination
Latch holder fastening
Square contact shape
UL94 V-0 flammability rating

Engineering Selection Recommendations

Active Product Availability: All substitute parts maintain active product status, ensuring long-term availability and supply chain continuity. The DF1E-7P-2.5DS is obsolete and should be replaced in new designs.

RoHS Compliance Consideration: For applications requiring RoHS3 compliance, select 0705530006, 0705530041, or 5-103634-6. These parts meet current environmental regulations. TE Connectivity AMPMODU MTE series parts (103634-6 through 103906-6) are RoHS non-compliant and should be avoided in regulated applications.

Pitch Accommodation: The 0.002" (0.04mm) pitch difference between the DF1E-7P-2.5DS (2.50mm) and all substitutes (2.54mm) requires mechanical evaluation. Mating connectors or cable assemblies must be sourced for 2.54mm pitch to ensure proper engagement and contact reliability.

Temperature Range Extension: Substitute parts operate across -40°C to -65°C minimum and 105°C maximum, exceeding the original -35°C to 85°C range. This provides thermal margin for applications approaching temperature extremes.

Contact Finish Selection: Gold-plated mating contacts (0705530006, 103635-6, 103673-6, 103904-6, 103906-6, 5-103635-6) provide enhanced corrosion resistance compared to tin finishes. Tin-finished alternatives (0705530041, 103634-6, 103672-6, 5-103634-6) are cost-effective for standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the DF1E-7P-2.5DS be directly replaced with a 2.54mm pitch substitute?

A: Direct mechanical replacement is not possible due to the 0.002" (0.04mm) pitch difference. The mating connector or cable assembly must be redesigned for 2.54mm pitch. The substitute header will not mate with existing 2.50mm pitch connectors.

Q: Which substitute offers the best RoHS compliance?

A: Molex 0705530006 and 0705530041 (SL 70553 series) and TE Connectivity 5-103634-6 are ROHS3 compliant. These parts meet current environmental directives and are suitable for regulated markets.

Q: What is the difference between TE Connectivity AMPMODU MTE variants?

A: Variants differ in contact finish (tin vs. gold), post finish thickness, and features. Models 103672-6, 103673-6, 103904-6, and 103906-6 include board lock and keying slot features. Models 103634-6, 103635-6, and 103906-6 include keying slot only. Contact finish affects corrosion resistance and cost.

Q: Are all substitutes rated for 3A current?

A: TE Connectivity AMPMODU MTE series parts (103634-6 through 5-103635-6) are rated for 3A. Molex SL 70553 series (0705530006, 0705530041) do not specify current rating in available data.

Q: What is the operating temperature difference?

A: The DF1E-7P-2.5DS operates -35°C to 85°C. Molex substitutes extend to -40°C to 105°C. TE Connectivity substitutes extend to -65°C to 105°C, providing wider thermal operating range.

Q: Can I use these substitutes in automotive applications?

A: Yes. All substitute parts list automotive applications. TE Connectivity AMPMODU MTE series explicitly supports automotive, general purpose, industrial, medical, and telecommunications applications.
