Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-103817-2 serves as a direct functional substitute for the 103817-2. Both parts are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical and electrical specifications across all critical parameters.

Product Status Consideration: The main part 103817-2 carries Last Time Buy status, indicating production discontinuation. The substitute part 5-103817-2 maintains Active product status with significantly higher inventory availability (2374 pieces versus 844 pieces), ensuring long-term procurement viability.

Compliance Advantage: The substitute part 5-103817-2 achieves RoHS Compliance, whereas the main part 103817-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies compliance obligations while maintaining full functional equivalence.

Contact Finish Specification: The main part features Tin-Lead post finish, while the substitute part specifies Tin post finish. Both finishes maintain identical contact finish thickness (100.0µin / 2.54µm) and are functionally equivalent for solder termination applications.

Packaging Consideration: The main part is supplied in Tube packaging, while the substitute is supplied in Bulk packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 103817-2 and 5-103817-2 mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including 12 positions in 3 rows, 0.100" (2.54mm) pitch spacing, through-hole mounting, and all contact dimensions. Direct substitution in PCB designs is supported without layout modifications.

Q: What is the difference between Tin-Lead and Tin post finishes?

A: The main part specifies Tin-Lead post finish while the substitute specifies Tin post finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm) and provide equivalent solderability and electrical performance for through-hole solder termination applications.

Q: Does the RoHS compliance difference affect functional performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing requirements, not electrical or mechanical performance. The substitute part 5-103817-2 achieves RoHS Compliance while maintaining identical electrical specifications and operating characteristics.

Q: Can I use the substitute part in existing designs without circuit modifications?

A: Yes. The substitute part 5-103817-2 maintains full electrical and mechanical equivalence across all specified parameters. No circuit modifications, PCB layout changes, or firmware updates are required.

Q: What is the significance of the different packaging formats?

A: The main part is supplied in Tube packaging while the substitute is supplied in Bulk packaging. This affects component handling, storage, and pick-and-place automation compatibility but does not impact electrical performance or mechanical fit.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 103817-2 and 5-103817-2 operate across the identical temperature range of -65°C to 105°C and maintain the same UL94 V-0 flammability rating.

Q: What inventory considerations should guide part selection?

A: The substitute part 5-103817-2 maintains significantly higher inventory (2374 pieces) compared to the main part 103817-2 (844 pieces). For new production programs, the substitute part ensures superior supply chain continuity given the main part's Last Time Buy status.
