Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 745496-2 with the active equivalent 1-745496-7 is based on strict electrical and mechanical parameter alignment. Both connectors share identical core specifications: D-Sub connector style, 25 position plug configuration with male pins, 2-row layout, DB/B shell size (Size 3), free hanging in-line mounting, IDC and discrete wire termination capability, steel tin-plated shell construction, gold contact finish, 250V voltage rating, and -55°C to 105°C operating temperature range. Both connectors feature phosphor bronze contact material, thermoplastic glass-filled dielectric, UL94 V-0 flammability rating, and grounding indents. The primary distinction is wire gauge compatibility: the main part 745496-2 accommodates 22-26 AWG wire, while the substitute 1-745496-7 accommodates 26-30 AWG wire. This difference reflects design optimization rather than functional incompatibility within overlapping wire gauge ranges. The substitute part is active and ROHS3 compliant, addressing obsolescence and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-745496-7 is the direct active equivalent for the obsolete 745496-2 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part 1-745496-7 maintains active product status, ensuring ongoing availability, manufacturing support, and supply chain reliability. The main part 745496-2 is classified as obsolete, creating supply constraints and discontinuation risk.

Regulatory Compliance: The substitute part 1-745496-7 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The main part 745496-2 is RoHS non-compliant with undefined REACH status, presenting compliance barriers for new designs and regulated applications.

Electrical and Mechanical Equivalence: Both connectors share identical specifications across all critical parameters: connector style, pin configuration, shell size, mounting type, termination capability, material composition, contact finish, voltage rating, and operating temperature range. The wire gauge specification difference (22-26 AWG versus 26-30 AWG) reflects design optimization and does not preclude substitution for applications utilizing 26 AWG wire, which falls within both specifications.

Series Continuity: Both parts belong to the AMPLIMITE HDE-20 series, ensuring mechanical and electrical compatibility with existing mating connectors and system designs.

Frequently Asked Questions (FAQ)

Q: Can the 1-745496-7 directly replace the 745496-2 in existing applications?

A: Yes. Both connectors are mechanically and electrically equivalent across all critical parameters. They share identical D-Sub 25 position plug configuration, shell size, mounting type, termination methods, and electrical ratings. Direct substitution is supported for applications using 26 AWG wire, which falls within both wire gauge specifications.

Q: What is the significance of the wire gauge difference between the two parts?

A: The main part 745496-2 accommodates 22-26 AWG wire, while the substitute 1-745496-7 accommodates 26-30 AWG wire. The overlapping range at 26 AWG ensures compatibility for most applications. Applications requiring 22-25 AWG wire should confirm contact specifications with the connector manufacturer to ensure proper termination force and contact retention.

Q: Why is the 745496-2 classified as obsolete?

A: The 745496-2 is no longer in active production. The 1-745496-7 represents the current active equivalent in the AMPLIMITE HDE-20 series, providing ongoing manufacturing support and supply availability.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The 1-745496-7 is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement. The original part 745496-2 is RoHS non-compliant, which may restrict its use in regulated applications and new designs.

Q: Are there any packaging differences between the two parts?

A: The main part 745496-2 packaging is not specified in the available data. The substitute part 1-745496-7 is supplied in bulk packaging. Confirm packaging requirements with your procurement department to ensure compatibility with assembly and inventory management processes.

Q: What is the contact finish specification for both connectors?

A: Both connectors feature gold contact finish with 30.0µin (0.76µm) thickness, ensuring consistent electrical performance and corrosion resistance across both parts.

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

A: Yes. Both connectors operate across the identical temperature range of -55°C to 105°C, supporting applications across industrial, commercial, and military temperature specifications.

Q: What termination methods are supported by the substitute connector?

A: The 1-745496-7 supports both IDC (Insulation Displacement Contact) and discrete wire termination, matching the capabilities of the original 745496-2 connector.
