Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745653-5 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
• Material Composition: Must be metal with zinc alloy construction
• Plating Specification: Must be nickel over copper
• Accessory Type: Must be two-piece backshell
• Cable Type: Must accommodate round cable
• Features: Must include slide lock mechanism

The substitute part 5745653-5 meets all these parameters and is classified as an active product with improved compliance status, making it a direct functional and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 5745653-5 is the direct active equivalent for the obsolete 745653-5. All mechanical, electrical, and dimensional parameters are identical. The substitute part offers the following advantages:

Product Status: The 5745653-5 maintains active product status, ensuring continued availability and manufacturer support, whereas the 745653-5 is obsolete and subject to discontinuation.

Regulatory Compliance: The 5745653-5 is RoHS compliant, meeting current environmental regulations. The original part is RoHS non-compliant, which may present compliance challenges for new designs or applications subject to RoHS requirements.

REACH Status: The 5745653-5 has a defined REACH status (REACH Affected), providing clarity on substance compliance. The original part has an undefined REACH status from the vendor.

Functional Equivalence: Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE series and share identical specifications for connector configuration, shielding, material composition, and mechanical features.

For applications requiring new procurement or long-term supply assurance, the 5745653-5 is the appropriate selection. For legacy systems currently using the 745653-5, direct substitution is mechanically and electrically valid.
