Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-102523-5

The 5-102523-5 is the preferred direct substitute for the obsolete 102523-5. This part maintains identical electrical and mechanical specifications including pitch (0.100" / 2.54mm), contact material (phosphor bronze), operating temperature range (-65°C ~ 105°C), and current rating (3A). The 5-102523-5 carries active product status and RoHS compliance, ensuring long-term availability and regulatory alignment. The only material difference is the contact finish specification (tin versus tin-lead), which does not affect functional compatibility in standard solder applications.

Secondary Recommendations: Pitch Variant Substitutes

The Molex 0534260710, Hirose DF1B-7P-2.5DS(01), and Hirose DF1BZ-7P-2.5DS are viable substitutes when pitch variance of 0.002" (0.50mm) is acceptable within the application design. These parts maintain the core functional requirements: 7-position headers, male pin contacts, through-hole right-angle mounting, and shrouded 4-wall construction.

Compliance Considerations:

All substitute parts meet UL94 V-0 flammability requirements. The 5-102523-5 is RoHS compliant, matching modern regulatory standards. The Molex and Hirose variants carry ROHS3 compliance, providing enhanced regulatory coverage. Selection should account for operating temperature requirements: the 102523-5 and 5-102523-5 support -65°C to 105°C, while Hirose variants are limited to -35°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can the 5-102523-5 be used as a direct replacement for the 102523-5?

A: Yes. The 5-102523-5 is a direct functional equivalent with identical pitch (0.100" / 2.54mm), position count (7), contact type (male pin), mounting configuration (through-hole right-angle), and electrical ratings (3A, -65°C ~ 105°C). The primary difference is product status (active versus obsolete) and RoHS compliance, both favoring the 5-102523-5 for new designs and ongoing procurement.

Q: What is the impact of using a 0.098" (2.50mm) pitch substitute instead of 0.100" (2.54mm)?

A: The 0.002" (0.50mm) pitch difference requires verification against PCB layout and mating connector specifications. This variance is not interchangeable without mechanical redesign. Molex 0534260710, Hirose DF1B-7P-2.5DS(01), and Hirose DF1BZ-7P-2.5DS are only suitable if the application design accommodates 2.50mm pitch spacing.

Q: Are there differences in contact material between the main part and substitutes?

A: Yes. The 102523-5 and 5-102523-5 use phosphor bronze contacts, while Hirose variants (DF1B-7P-2.5DS(01) and DF1BZ-7P-2.5DS) use brass contacts. Molex 0534260710 uses phosphor bronze. Contact material differences may affect electrical properties and corrosion resistance in specific environments; application requirements should guide selection.

Q: What are the packaging differences among substitute parts?

A: The 102523-5 is supplied without specified packaging. The 5-102523-5 is packaged in tubes. Molex 0534260710 is supplied in trays. Hirose variants (DF1B-7P-2.5DS(01) and DF1BZ-7P-2.5DS) are supplied in bulk. Packaging affects handling, storage, and procurement logistics but does not impact electrical or mechanical function.

Q: Which substitute part has the widest operating temperature range?

A: The TE Connectivity 5-102523-5 maintains the original -65°C ~ 105°C operating range, matching the obsolete 102523-5. The Molex 0534260710 supports -40°C ~ 105°C. Hirose variants are limited to -35°C ~ 85°C. Temperature range selection depends on application environment requirements.

Q: Are all substitute parts RoHS compliant?

A: The 5-102523-5 is RoHS compliant. Molex 0534260710 and Hirose DF1BZ-7P-2.5DS are ROHS3 compliant. Hirose DF1B-7P-2.5DS(01) is RoHS compliant. All parts meet flammability requirements (UL94 V-0). Regulatory compliance should be verified against specific application and regional requirements.

Q: What is the difference between DF1B-7P-2.5DS(01) and DF1BZ-7P-2.5DS?

A: Both are Hirose DF1B series 7-position headers with 2.50mm pitch. The primary differences are contact finish (gold versus tin) and voltage rating (250V versus 150V). The DF1B-7P-2.5DS(01) with gold plating provides enhanced corrosion resistance. Selection depends on voltage requirements and environmental exposure.

Q: Can the Molex 0534260710 be used in applications requiring 3A current rating?

A: The Molex 0534260710 current rating varies by wire gauge and is not specified as a fixed 3A rating. Applications requiring guaranteed 3A capacity should use the TE Connectivity 102523-5, 5-102523-5, or verify Molex specifications against wire gauge and termination method.
