Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1658642-1

The 1658642-1 is the recommended substitute for the obsolete 745906-2. This selection is based on the following engineering factors:

Product Status: The 1658642-1 maintains active product status with current manufacturing support, whereas the 745906-2 is obsolete and subject to discontinuation of supply.

Regulatory Compliance: The 1658642-1 is ROHS3 compliant and REACH unaffected, providing superior compliance posture for new designs and applications subject to environmental regulations. The 745906-2 is RoHS non-compliant and REACH affected, limiting its applicability in regulated markets.

Mechanical and Electrical Equivalence: Both parts are identical across all functional parameters including connector style, position count, shell size, mounting configuration, material composition, and feature set. Direct substitution is supported without design modification.

Supply Availability: The 1658642-1 is available in active inventory with bulk packaging options, ensuring reliable procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1658642-1 be used as a direct replacement for the 745906-2 in existing designs?

A: Yes. The 1658642-1 is mechanically and electrically equivalent to the 745906-2 across all specified parameters. Both parts are D-Sub 9-position plug housings in the AMPLIMITE HDP-20 series with identical shell size, mounting type, flange configuration, and material specifications. Direct substitution is supported without design changes.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and regulatory compliance. The 745906-2 is obsolete and RoHS non-compliant, while the 1658642-1 is active and ROHS3 compliant. The 1658642-1 also specifies shell finish thickness at 200µin (5.08µm), whereas the 745906-2 does not provide this specification.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The 1658642-1 is supplied in bulk packaging, while the 745906-2 packaging is not specified. Bulk packaging is standard for active production parts and supports high-volume procurement requirements.

Q: Does the substitute part require different contact specifications?

A: No. Both the 745906-2 and 1658642-1 are housings for male contacts and do not include contacts. Contact selection and specifications remain independent of the housing choice and are determined by application requirements.

Q: What is the significance of the REACH status difference?

A: The 1658642-1 is REACH unaffected, indicating compliance with European chemical regulations without substance restrictions. The 745906-2 is REACH affected, which may impose supply chain constraints or require additional documentation for applications in regulated markets.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The parts are functionally equivalent and maintain identical form, fit, and function characteristics. Both are compatible with the same contact sets, mating connectors, and mounting configurations within the AMPLIMITE HDP-20 series.
