Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 102523-2 is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (3), pitch spacing (0.100" / 2.54mm), mounting configuration (through-hole right-angle), shrouding style (shrouded 4-wall), termination method (solder), and fastening mechanism (push-pull). The operating temperature range, current rating, and flammability rating establish the performance envelope for acceptable substitutes.

The identified substitute parts are grouped into two categories:

Category 1: Direct Series Equivalent TE Connectivity 103361-1 maintains identical electrical and mechanical specifications within the AMPMODU Mod II series, with the primary distinction being active product status and alternative contact finish specifications.

Category 2: Cross-Manufacturer Alternatives Hirose Electric DF1B-3P-2.5DS(01) and DF1BZ-3P-2.5DS represent alternative connector architectures with modified pitch spacing (0.098" / 2.50mm), different contact materials (brass versus phosphor bronze), and altered operating temperature ranges. These parts require mechanical and electrical compatibility verification at the application level.

Engineering Selection Recommendations

TE Connectivity 103361-1 is the primary equivalent substitute for the obsolete 102523-2. Both components share identical mechanical and electrical specifications within the AMPMODU Mod II series, including pitch spacing, position count, mounting configuration, and operating temperature range. The 103361-1 maintains active product status and is available in higher inventory quantities. The contact finish difference (gold versus tin-lead) provides enhanced corrosion resistance and contact reliability. This part is suitable for direct replacement in applications requiring the full -65°C to 105°C operating range and 3A current capacity.

Hirose Electric DF1B-3P-2.5DS(01) and DF1BZ-3P-2.5DS are alternative cross-manufacturer options with the following considerations: both parts feature reduced pitch spacing (0.098" / 2.50mm versus 0.100" / 2.54mm), which requires PCB layout modification and connector interface compatibility verification. The operating temperature range is reduced to -35°C to 85°C, limiting applicability in extended temperature environments. Both Hirose alternatives carry ROHS3 compliance and REACH unaffected status, providing regulatory advantages for new designs. The DF1B-3P-2.5DS(01) features gold mating contact finish, while the DF1BZ-3P-2.5DS provides tin finish with lower voltage rating (150V versus 250V).

Selection between these alternatives depends on application requirements: use 103361-1 for direct replacement with maintained specifications; use Hirose alternatives only when PCB redesign is acceptable and operating temperature requirements do not exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 103361-1 be used as a direct replacement for the 102523-2?

A: Yes. The 103361-1 maintains identical pitch spacing (0.100" / 2.54mm), position count (3), mounting type (through-hole right-angle), shrouding configuration (4-wall), and operating temperature range (-65°C to 105°C). The primary difference is contact finish specification (gold versus tin-lead) and active product status. No PCB layout modifications are required.

Q: What are the key differences between the TE Connectivity 103361-1 and the Hirose DF1B series?

A: The primary differences are pitch spacing (0.100" for 103361-1 versus 0.098" for DF1B series), contact material (phosphor bronze versus brass), and operating temperature range (-65°C to 105°C for 103361-1 versus -35°C to 85°C for DF1B series). The Hirose parts include keying slot features and require PCB redesign due to pitch modification.

Q: Are the Hirose DF1B-3P-2.5DS(01) and DF1BZ-3P-2.5DS interchangeable with each other?

A: Both Hirose parts share identical mechanical specifications and pitch spacing (0.098" / 2.50mm). The primary distinction is contact finish (gold for DF1B-3P-2.5DS(01) versus tin for DF1BZ-3P-2.5DS) and voltage rating (250V versus 150V). Interchangeability depends on application voltage requirements and contact reliability specifications.

Q: What packaging formats are available for these substitute parts?

A: The TE Connectivity 103361-1 is supplied in tube packaging. Both Hirose alternatives (DF1B-3P-2.5DS(01) and DF1BZ-3P-2.5DS) are supplied in bulk packaging. Packaging selection may affect procurement lead times and handling requirements.

Q: Do the Hirose alternatives require PCB layout modifications?

A: Yes. The Hirose DF1B series components feature 0.098" (2.50mm) pitch spacing compared to the 0.100" (2.54mm) pitch of the TE Connectivity parts. This 0.002" (0.50mm) difference requires PCB footprint redesign and connector interface verification before implementation.

Q: What is the compliance status difference between the main part and substitutes?

A: The 102523-2 is RoHS non-compliant with undefined REACH status. The TE Connectivity 103361-1 carries not applicable RoHS status. Both Hirose alternatives (DF1B-3P-2.5DS(01) and DF1BZ-3P-2.5DS) are ROHS3 compliant and REACH unaffected, providing regulatory advantages for new product designs.

Q: Can the 102523-2 be used in applications requiring temperatures below -35°C?

A: Yes. The 102523-2 operates from -65°C to 105°C, supporting extended low-temperature applications. The Hirose alternatives are limited to -35°C minimum, making them unsuitable for applications requiring operation below -35°C.
