Substitute Part Grouping Explanation

Substitution of the TE Connectivity 102203-7 is determined by the following critical parameters: connector type (header), contact type (male pin), pitch specification, number of positions, mounting configuration (through-hole right-angle), shrouding design (4-wall), termination method (solder), and fastening mechanism (push-pull). Parts are grouped into two categories based on substitution compatibility:

Direct Equivalent (Same Pitch - 0.100" / 2.54mm): The part 5-102203-7 maintains identical electrical and mechanical specifications to the main part, differing only in packaging format (tube versus standard) and product status (active versus obsolete). This part is a direct functional replacement.

Similar Substitute (Different Pitch - 0.098" / 2.50mm): The Hirose Electric parts DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS operate at a slightly different pitch specification (0.098" / 2.50mm). These parts share the same connector type, contact type, number of positions, mounting configuration, shrouding, termination, and fastening mechanism. The pitch variance of 0.02mm represents a dimensional difference that requires mechanical compatibility verification at the mating interface.

Parameter Comparison

Engineering Selection Recommendations

5-102203-7 (Direct Equivalent - Recommended Primary Substitute): The 5-102203-7 is the preferred substitute for the obsolete 102203-7. Both parts are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications, including pitch (0.100" / 2.54mm), contact dimensions, operating temperature range (-65°C ~ 105°C), and current rating (3A). The primary distinction is product status: 5-102203-7 is active with significantly higher inventory availability (12349 pcs versus 896 pcs). Additionally, 5-102203-7 achieves RoHS compliance, whereas the original part is RoHS non-compliant. This part provides direct form-fit-function replacement without design modification.

DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS (Similar Substitutes - Conditional Use): The Hirose Electric parts maintain functional compatibility in connector type, contact type, number of positions, mounting configuration, shrouding, termination, and fastening mechanism. However, these parts operate at a different pitch specification (0.098" / 2.50mm versus 0.100" / 2.54mm), resulting in a 0.02mm dimensional variance. This pitch difference affects mating interface compatibility and requires mechanical verification against the corresponding receptacle or cable connector. Additional considerations include reduced operating temperature range (-35°C ~ 85°C versus -65°C ~ 105°C), different contact materials (brass versus phosphor bronze), and different insulation materials (polyamide/nylon versus thermoplastic). Both Hirose parts are RoHS compliant and actively manufactured. These parts are suitable only when the mating interface is confirmed compatible with the 2.50mm pitch specification and the reduced temperature range is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can 5-102203-7 be used as a direct replacement for 102203-7?

A: Yes. The 5-102203-7 is a direct equivalent with identical electrical and mechanical specifications. Both parts share the same pitch (0.100" / 2.54mm), contact dimensions, operating temperature range, current rating, and connector configuration. The primary differences are packaging format (tube versus standard) and product status (active versus obsolete). No design modification is required.

Q: What is the pitch difference between the TE Connectivity and Hirose parts?

A: The TE Connectivity 102203-7 and 5-102203-7 operate at 0.100" (2.54mm) pitch. The Hirose DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS operate at 0.098" (2.50mm) pitch. This represents a 0.02mm difference per position. For a 10-position connector, the cumulative dimensional variance is approximately 0.2mm across the connector width. This variance requires verification of mating interface compatibility.

Q: Are the Hirose parts compatible with existing TE Connectivity receptacles?

A: Compatibility depends on the specific receptacle design and tolerance specifications. The 0.02mm pitch variance may result in improper mating or contact engagement issues. Mechanical compatibility must be verified through dimensional analysis or physical testing before substitution in production applications.

Q: What is the operating temperature difference between the parts?

A: The TE Connectivity 102203-7 and 5-102203-7 operate across -65°C to 105°C. The Hirose DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS operate across -35°C to 85°C. The Hirose parts have a reduced temperature range of 30°C on the low end and 20°C on the high end. Applications requiring operation below -35°C or above 85°C are not suitable for Hirose substitutes.

Q: What are the RoHS compliance differences?

A: The original 102203-7 is RoHS non-compliant. The 5-102203-7 is RoHS compliant. Both Hirose parts (DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS) are RoHS compliant. For applications requiring RoHS compliance, the 5-102203-7 is the appropriate choice among TE Connectivity options.

Q: What contact material differences exist between the parts?

A: The TE Connectivity parts (102203-7 and 5-102203-7) use phosphor bronze contacts. The Hirose parts (DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS) use brass contacts. Phosphor bronze provides superior spring characteristics and contact durability compared to brass. This material difference may affect contact force, mating cycles, and long-term reliability.

Q: What is the difference between DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS?

A: Both parts share identical mechanical specifications and pitch. The primary differences are contact finish and voltage rating. DF1B-10P-2.5DS(01) features gold-plated mating contacts (8.00µin thickness) with a 250V voltage rating. DF1BZ-10P-2.5DS features tin-plated mating contacts (39.4µin thickness) with a 150V voltage rating. Gold plating provides superior corrosion resistance and lower contact resistance, making DF1B-10P-2.5DS(01) preferable for most applications.

Q: What packaging formats are available?

A: The 102203-7 is supplied in standard packaging. The 5-102203-7 is supplied in tube packaging. The Hirose parts (DF1B-10P-2.5DS(01) and DF1BZ-10P-2.5DS) are supplied in bulk packaging. Packaging format affects handling, storage, and automated assembly compatibility. Verify packaging requirements for your procurement and assembly processes.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring direct compatibility with existing TE Connectivity receptacles and the full operating temperature range, select 5-102203-7. For applications where pitch variance is acceptable and reduced operating temperature range is suitable, either Hirose part may be considered. DF1B-10P-2.5DS(01) is preferred over DF1BZ-10P-2.5DS due to superior contact finish and higher voltage rating.
