TE Connectivity AMP Connectors 745122-2 D-Sub Backshell Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 745122-2 is a 15 Position Two Piece Backshell Connector with 180° cable exit, designed for D-Sub connector assemblies. This component is classified as an accessory backshell for AMPLIMITE series connectors and is currently listed as obsolete. The part is unshielded, constructed from polyamide (nylon) material, and features mating screws rated at 4-40. Due to its obsolete product status, identification of equivalent substitute parts is necessary for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

Substitution of the 745122-2 is determined by strict equivalence across the following critical parameters: 15-position connector count, Shell Size A compatibility, support for both 15pos and HD26pos D-Sub sizes, 180° cable exit orientation, round cable type, unshielded configuration, polyamide material composition, black color, and 4-40 mating screw specification. The substitute part 5745122-2 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional interchangeability within D-Sub backshell applications. Differences in product status, packaging format, and regulatory compliance do not affect the core substitution relationship.

Engineering Selection Recommendations

The 5745122-2 serves as the direct substitute for the obsolete 745122-2 part number. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical mechanical and electrical specifications for D-Sub backshell applications. The primary distinction between the two parts is regulatory compliance status: the 5745122-2 is ROHS3 compliant and carries active product status, whereas the 745122-2 is RoHS non-compliant and obsolete. For new designs and ongoing procurement where regulatory compliance is required, the 5745122-2 is the appropriate selection. The substitute part is available in bulk packaging and maintains full compatibility with 15-position D-Sub connectors, Shell Size A, and all specified mechanical parameters including the 180° cable exit configuration and 4-40 mating screws.

Frequently Asked Questions (FAQ)

Q: Can the 5745122-2 be used as a direct replacement for the 745122-2 in existing assemblies?

A: Yes. The 5745122-2 maintains identical mechanical and electrical specifications across all critical parameters including position count, shell size, cable exit angle, material composition, and mating hardware. Direct substitution is supported for D-Sub backshell applications.

Q: What is the primary reason for substituting the 745122-2?

A: The 745122-2 is classified as obsolete. The 5745122-2 is the active equivalent part from TE Connectivity AMP Connectors and is recommended for all new procurement and system maintenance.

Q: Are there compatibility differences between the two part numbers?

A: No. Both parts are compatible with 15-position D-Sub connectors, Shell Size A, and support both 15pos and HD26pos D-Sub sizes. Cable exit angle, shielding configuration, and material composition are identical.

Q: What is the difference in RoHS compliance between these parts?

A: The 745122-2 is RoHS non-compliant. The 5745122-2 is ROHS3 compliant. For applications requiring regulatory compliance with RoHS3 standards, the 5745122-2 is the appropriate selection.

Q: Does packaging format affect the substitution?

A: Packaging format does not affect functional or mechanical compatibility. The 5745122-2 is supplied in bulk packaging. Packaging selection should be based on procurement and inventory requirements rather than technical compatibility.

Q: Are the mating screw specifications identical?

A: Yes. Both parts feature mating screws rated at 4-40, ensuring identical assembly and installation characteristics.

Q: What is the moisture sensitivity level for both parts?

A: Both the 745122-2 and 5745122-2 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
