Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1E-13P-2.5DS(05) is based on the following critical parameters that must align for functional compatibility:

Primary Compatibility Criteria:

• Number of positions: 13
• Connector type: Header with male pins
• Mounting configuration: Through hole, right angle
• Shrouding: 4-wall shrouded construction
• Termination method: Solder
• Fastening type: Latch holder
• Contact shape: Square

Secondary Compatibility Considerations:

• Pitch tolerance: The main part operates at 0.098" (2.50mm) pitch. Substitute parts at 0.100" (2.54mm) pitch represent a minor pitch variation (0.02mm difference) that may require PCB redesign or mechanical accommodation
• Operating temperature range: Substitutes must support the application's thermal requirements
• Current rating: Substitutes must meet or exceed the 3A current specification
• Flammability rating: UL94 V-0 compliance maintained across all substitutes

The three substitute parts listed below maintain the core functional architecture while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

0705550047 (Molex SL 70555 Series)

This connector is actively manufactured and maintains full functional compatibility with the DF1E-13P-2.5DS(05) across all critical parameters. The primary design consideration is the pitch difference: 0.100" (2.54mm) versus 0.098" (2.50mm). This 0.02mm per-position variance accumulates to approximately 0.26mm across the 13-position span, requiring PCB footprint modification. The Molex part features gold-plated mating contacts and phosphor bronze contact material, offering enhanced corrosion resistance. Operating temperature range extends to 105°C, exceeding the original specification. RoHS3 compliance and REACH unaffected status support modern supply chain requirements. Voltage rating of 250V is specified, whereas the original part does not list this parameter.

1-103634-2 (TE Connectivity AMPMODU MTE Series)

This connector provides active product status with identical 13-position, 0.100" (2.54mm) pitch configuration. The same pitch consideration applies as noted above. TE Connectivity specifies tin-lead contact finish on both mating and post surfaces, with brass contact material matching the original design. Operating temperature range of -65°C to 105°C exceeds the original specification. The part includes a keying slot feature not present in the original. Current rating of 3A matches the original specification exactly. RoHS non-compliance and REACH affected status indicate this part may not align with modern regulatory requirements for new designs.

6-103635-2 (TE Connectivity AMPMODU MTE Series)

This connector is actively manufactured and represents the most direct functional equivalent to the DF1E-13P-2.5DS(05). It maintains identical position count, pitch, and mounting configuration. The gold-plated mating contact finish provides enhanced durability compared to the original tin finish. Brass contact material and thermoplastic insulation align with the original design intent. Operating temperature range of -65°C to 105°C and 3A current rating both meet or exceed original specifications. RoHS3 compliance and undefined REACH status provide flexibility for modern supply chain integration. The keying slot feature adds mechanical security not present in the original design.

For new designs, 6-103635-2 is preferred due to RoHS3 compliance and active manufacturing status. For direct replacement in existing applications, either TE Connectivity option accommodates the pitch transition with PCB modification. The Molex alternative offers equivalent performance with different contact material characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.100" (2.54mm) pitch connector as a direct replacement for the 0.098" (2.50mm) pitch original?

A: The substitute parts operate at 0.100" (2.54mm) pitch, which differs from the original 0.098" (2.50mm) pitch. This 0.02mm per-position difference accumulates across the 13-position connector. Direct PCB-level substitution without footprint modification is not possible. PCB redesign or mechanical accommodation is required.

Q: What is the significance of the contact finish differences between the substitute parts?

A: The original DF1E-13P-2.5DS(05) features tin-plated mating contacts. Substitute parts offer either tin, tin-lead, or gold plating. Gold plating (0705550047 and 6-103635-2) provides superior corrosion resistance and lower contact resistance, beneficial for high-reliability applications. Tin and tin-lead finishes are cost-effective alternatives suitable for standard industrial applications.

Q: Do all substitute parts maintain the same current rating?

A: The DF1E-13P-2.5DS(05) and both TE Connectivity substitutes (1-103634-2 and 6-103635-2) are rated for 3A. The Molex 0705550047 does not specify a current rating in the provided data. For applications requiring confirmed 3A capacity, the TE Connectivity options provide explicit specification alignment.

Q: Which substitute part is best for new product designs?

A: The 6-103635-2 (TE Connectivity) is recommended for new designs based on RoHS3 compliance, active manufacturing status, and 3A current rating specification. PCB footprint must accommodate the 0.100" (2.54mm) pitch standard.

Q: Are there temperature range differences I should consider?

A: The original part operates from -35°C to 85°C. All three substitute parts extend the upper temperature limit to 105°C. The TE Connectivity substitutes additionally extend the lower limit to -65°C. For applications within the original -35°C to 85°C range, all substitutes are thermally compatible. Applications requiring extended low-temperature operation benefit from the TE Connectivity options.

Q: What is the impact of the keying slot feature on the TE Connectivity substitutes?

A: The TE Connectivity parts (1-103634-2 and 6-103635-2) include a keying slot feature not present in the original DF1E-13P-2.5DS(05). This feature provides mechanical polarization to prevent incorrect mating orientation. Mating connectors must be compatible with this keying configuration. This is a functional enhancement that does not prevent substitution but requires verification of mating connector compatibility.

Q: What are the RoHS and REACH compliance implications?

A: The 6-103635-2 is RoHS3 compliant with undefined REACH status. The 1-103634-2 is RoHS non-compliant with REACH affected status. The 0705550047 is RoHS3 compliant and REACH unaffected. For applications subject to RoHS3 requirements, 6-103635-2 and 0705550047 are suitable. For REACH-restricted applications, 0705550047 is the preferred choice.
