Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 102203-1 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Pitch - 0.100" / 2.54mm): The part 5-102203-1 is a direct equivalent within the same AMPMODU Mod II series. This substitute maintains identical mating pitch, position count, mounting configuration, shrouding design, and termination method. The primary difference is the contact finish on the post (Tin versus Tin-Lead) and RoHS compliance status (ROHS3 Compliant versus Not Applicable).

Similar Substitutes (Comparable Pitch - 0.098" / 2.50mm): The Hirose Electric DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS are similar rectangular connectors with 4 positions, through-hole right-angle mounting, shrouded 4-wall design, and push-pull fastening. These parts operate at a slightly different mating pitch (0.098" / 2.50mm) compared to the primary part. Key parameters that determine substitution viability include connector type, contact type, number of positions, mounting orientation, shrouding configuration, termination method, and fastening mechanism. Operating temperature ranges, voltage ratings, and contact material composition differ and must be evaluated against specific application requirements.

Engineering Selection Recommendations

5-102203-1 (Direct Equivalent): This part is the primary substitute for the 102203-1. Both parts share identical electrical and mechanical specifications within the AMPMODU Mod II series, including mating pitch, position count, mounting configuration, and operating temperature range. The 5-102203-1 offers ROHS3 compliance and higher inventory availability (3412 pieces). Selection of this part is appropriate where RoHS compliance is required or preferred and where the identical pitch and form factor are critical to the application.

DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS (Similar Substitutes): These Hirose Electric connectors are functionally similar but operate at a different mating pitch (0.098" / 2.50mm versus 0.100" / 2.54mm). Both parts maintain the same connector type, contact configuration, mounting style, shrouding, and termination method. The operating temperature range is reduced (-35°C ~ 85°C versus -65°C ~ 105°C), and contact materials differ (Brass versus Phosphor Bronze). These parts are suitable for applications where the 0.02mm pitch tolerance is acceptable and where the reduced operating temperature range does not conflict with system requirements. Both Hirose parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. Selection between DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS depends on voltage rating requirements (250V versus 150V) and contact finish specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-102203-1 be used as a direct replacement for the 102203-1?

A: Yes. The 5-102203-1 is a direct equivalent within the AMPMODU Mod II series. Both parts share identical mating pitch (0.100" / 2.54mm), position count (4), mounting configuration (through-hole right-angle), shrouding design (4-wall), termination method (solder), and operating temperature range (-65°C ~ 105°C). The primary difference is RoHS compliance status.

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

A: The primary difference is mating pitch. The TE Connectivity 102203-1 and 5-102203-1 operate at 0.100" (2.54mm) pitch, while the Hirose DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS operate at 0.098" (2.50mm) pitch. Additionally, the Hirose parts have a reduced operating temperature range (-35°C ~ 85°C) and use Brass contact material instead of Phosphor Bronze.

Q: Are the Hirose parts compatible with the same mating connectors as the TE Connectivity parts?

A: No. The 0.02mm pitch difference between the TE Connectivity parts (2.54mm) and Hirose parts (2.50mm) means they are not compatible with the same mating connectors. Mating connectors must be specifically designed for the corresponding pitch.

Q: What is the difference between DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS?

A: Both are Hirose DF1B series 4-position headers with 0.098" (2.50mm) pitch. The DF1B-4P-2.5DS(01) has gold-plated mating contacts (8.00µin thickness) and no specified post finish. The DF1BZ-4P-2.5DS has tin-plated mating contacts (39.4µin thickness) and tin-plated post finish. The voltage rating differs: DF1B-4P-2.5DS(01) is rated at 250V, while DF1BZ-4P-2.5DS is rated at 150V.

Q: Which substitute part should I select if RoHS compliance is required?

A: The 5-102203-1 is ROHS3 compliant and maintains identical specifications to the 102203-1. Both Hirose parts (DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS) are also ROHS3 compliant. The original 102203-1 is listed as "Not applicable" for RoHS status.

Q: Can I use a Hirose part if my application requires operation below -35°C or above 85°C?

A: No. The Hirose DF1B series parts are rated for -35°C ~ 85°C operating temperature, which is narrower than the TE Connectivity parts (-65°C ~ 105°C). If your application requires operation outside the Hirose temperature range, the TE Connectivity 102203-1 or 5-102203-1 must be used.

Q: What packaging formats are available for these parts?

A: The TE Connectivity 102203-1 and 5-102203-1 are supplied in Tube packaging. The Hirose DF1B-4P-2.5DS(01) and DF1BZ-4P-2.5DS are supplied in Bulk packaging. Packaging format may affect handling, storage, and procurement workflows.

Q: Are all four substitute parts suitable for the same applications?

A: No. The 5-102203-1 is suitable for direct replacement of the 102203-1 in all applications. The Hirose parts are suitable only for applications where the 0.02mm pitch difference is acceptable, the operating temperature range (-35°C ~ 85°C) is sufficient, and the mating connector is specifically designed for the Hirose pitch specification.
