Engineering Selection Recommendations

Direct Replacement (Preferred): The TE Connectivity 5-102203-3 is the recommended substitute for the obsolete 102203-3. This part maintains identical electrical and mechanical specifications, including pitch, contact configuration, and operating temperature range. The 5-102203-3 offers active product status, ensuring long-term availability and supply chain stability. Additionally, this part achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet.

Alternative Substitutes: The Hirose Electric DF1B series connectors (DF1B-6P-2.5DS(01) and DF1BZ-6P-2.5DS) provide functional alternatives when the direct equivalent is unavailable. Both Hirose parts maintain the core connector architecture: 6-position header, through-hole right-angle mounting, shrouded 4-wall design, and push-pull fastening. Both parts are active products with ROHS3 compliance.

Compatibility Considerations: The Hirose alternatives operate at a reduced temperature range (-35°C ~ 85°C versus -65°C ~ 105°C) and feature a 0.098" (2.50mm) pitch versus the 0.100" (2.54mm) specification of the TE Connectivity parts. The DF1B-6P-2.5DS(01) features gold-plated mating contacts with brass material, while the DF1BZ-6P-2.5DS uses tin-plated contacts. Applications requiring the full -65°C ~ 105°C operating range or precise 2.54mm pitch spacing must use the TE Connectivity 5-102203-3.

Frequently Asked Questions (FAQ)

Q: Can the 5-102203-3 be used as a direct replacement for the 102203-3?

A: Yes. The 5-102203-3 is a direct equivalent with identical pitch (0.100" / 2.54mm), contact configuration, mounting type, and operating temperature range (-65°C ~ 105°C). The primary advantage is active product status and ROHS3 compliance.

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

A: The TE Connectivity 102203-3 and 5-102203-3 specify 0.100" (2.54mm) pitch. The Hirose DF1B series (DF1B-6P-2.5DS(01) and DF1BZ-6P-2.5DS) specify 0.098" (2.50mm) pitch. This 0.002" (0.04mm) difference may affect mechanical fit in applications with tight tolerance requirements.

Q: Are the Hirose DF1B connectors suitable for high-temperature applications?

A: The Hirose DF1B series operates within -35°C ~ 85°C, which is narrower than the TE Connectivity range of -65°C ~ 105°C. Applications requiring operation below -35°C or above 85°C must use the TE Connectivity 5-102203-3.

Q: What are the contact material differences between substitute options?

A: The TE Connectivity 102203-3 and 5-102203-3 use phosphor bronze contacts. The Hirose DF1B-6P-2.5DS(01) uses brass contacts with gold plating. The Hirose DF1BZ-6P-2.5DS uses brass contacts with tin plating. Contact material selection affects electrical conductivity and corrosion resistance characteristics.

Q: Are all substitute parts RoHS compliant?

A: The 5-102203-3, DF1B-6P-2.5DS(01), and DF1BZ-6P-2.5DS are all ROHS3 compliant. The original 102203-3 is RoHS non-compliant. For applications subject to RoHS regulations, use the 5-102203-3 or Hirose alternatives.

Q: What packaging options are available for these connectors?

A: The 102203-3 is supplied in standard packaging. The 5-102203-3 is supplied in tube packaging. The Hirose DF1B-6P-2.5DS(01) and DF1BZ-6P-2.5DS are supplied in bulk packaging. Packaging selection may affect procurement quantities and handling requirements.

Q: Can the Hirose DF1B connectors be used interchangeably with each other?

A: Both Hirose DF1B variants maintain identical mechanical configuration and pitch. The primary difference is contact finish: DF1B-6P-2.5DS(01) features gold-plated contacts, while DF1BZ-6P-2.5DS features tin-plated contacts. Selection depends on application requirements for contact resistance and corrosion performance.
