Engineering Selection Recommendations

The 172-E09-103R011 is the appropriate substitute for the obsolete 172-E09-102-011. Selection is based on the following factors:

Product Status: The main part is classified as obsolete, while the substitute is active and currently in production. This ensures long-term availability and supply chain continuity.

Compliance Status: The substitute part is ROHS3 compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations, the substitute provides regulatory compliance.

Functional Equivalence: All critical electrical and mechanical parameters are identical between the two parts, ensuring direct compatibility in existing designs and applications.

Difference in Shell Finish: The main part features tin plating while the substitute features nickel plating on the steel shell. Both finishes provide corrosion protection and are compatible with the gold-flashed contact finish specified for both parts.

Availability: The substitute part is available in significantly higher inventory (1334 pcs) compared to the main part (729 pcs), supporting both immediate procurement and long-term project requirements.

Frequently Asked Questions (FAQ)

Q: Can the 172-E09-103R011 be used as a direct replacement for the 172-E09-102-011?

A: Yes. Both connectors share identical connector style, type, position count, shell size, mounting configuration, termination method, current rating, temperature range, and contact materials. The parts are functionally and mechanically equivalent.

Q: What is the difference between tin plating and nickel plating on the shell?

A: Both finishes provide corrosion resistance on the steel shell. Tin plating offers lower contact resistance, while nickel plating provides enhanced durability in harsh environments. Both are compatible with the gold-flashed contact finish used in both parts.

Q: Why is the substitute part ROHS3 compliant while the main part is not?

A: The substitute part was manufactured to meet current RoHS3 regulations, which restrict hazardous substances in electrical and electronic equipment. The main part predates these requirements. For new designs or applications in regulated markets, the substitute ensures compliance.

Q: Are there any wire gauge specifications for the main part?

A: The main part does not specify wire gauge in the provided parameters. The substitute part accommodates 20-26 AWG wire. Verify wire gauge compatibility with your specific application requirements.

Q: What does MSL 1 (Unlimited) mean for the substitute part?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification, meaning the component can be stored indefinitely without special moisture control measures, providing flexibility in inventory management and storage conditions.

Q: Is the packaging difference significant for substitution?

A: Packaging format (tray for the substitute versus unspecified for the main part) does not affect functional compatibility. Packaging selection depends on your procurement, storage, and assembly process requirements.
