Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745653-4 is determined by strict equivalence across the following critical parameters:

• Number of Positions: Must be 25
• Compatible Shell Size: Must be B
• Compatible D-Sub Size: Must support 25pos and HD44pos
• Cable Exit Angle: Must be 90°
• Shielding Configuration: Must be shielded
• Accessory Type: Must be two-piece backshell
• Material Composition: Must be metal with zinc alloy construction
• Plating Specification: Must be nickel over copper
• Cable Type: Must accommodate round cables
• Features: Must include slide lock mechanism
• Color: Must be silver

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, compliance certifications, or packaging do not affect functional interchangeability when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 5745653-4 is a direct functional substitute for the obsolete 745653-4. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in applications currently using the 745653-4.

Product Status Consideration: The 5745653-4 maintains active product status with TE Connectivity, providing assured long-term availability compared to the obsolete 745653-4.

Compliance Advantage: The 5745653-4 is RoHS compliant, whereas the 745653-4 is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the 5745653-4 is the appropriate selection.

Packaging: The 5745653-4 is supplied in bulk packaging, which may differ from the original 745653-4 packaging specification. Bulk packaging does not affect component functionality or performance.

For new designs, maintenance applications, or compliance-driven requirements, the 5745653-4 is the recommended selection based on active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5745653-4 replace the 745653-4 in existing assemblies?

A: Yes. The 5745653-4 is functionally identical to the 745653-4 across all electrical and mechanical parameters, including position count, shell size, cable exit angle, shielding, material composition, and plating specification. Direct substitution is supported.

Q: What is the significance of the product status difference between these parts?

A: The 745653-4 is obsolete and no longer manufactured by TE Connectivity. The 5745653-4 is an active product with ongoing production and availability. For applications requiring long-term component sourcing, the 5745653-4 provides supply continuity.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. However, applications subject to RoHS regulations or environmental directives must use the RoHS-compliant 5745653-4. The 745653-4, being RoHS non-compliant, may not be acceptable in regulated environments.

Q: Are there any differences in the connector's mechanical interface?

A: No. Both parts feature identical shell size (B), position count (25), cable exit angle (90°), and two-piece backshell design. They are mechanically interchangeable.

Q: What does the bulk packaging mean for the 5745653-4?

A: Bulk packaging indicates the component is supplied without individual packaging, typically in larger quantities. This does not affect the component's performance or functionality. Bulk packaging is standard for high-volume procurement.

Q: Are both parts suitable for shielded D-Sub applications?

A: Yes. Both the 745653-4 and 5745653-4 are shielded backshell connectors designed for D-Sub 25-position and HD44-position configurations. Shielding characteristics are identical between the two parts.

Q: Can the 5745653-4 be used in applications originally designed for the 745653-4?

A: Yes. The 5745653-4 meets all functional requirements of the 745653-4 and is a direct substitute. No design modifications are required for component replacement.
