TE Connectivity Erni 223249 D-Sub Backshell Connector - Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 223249 is a D-Sub, D-shaped connector backshell assembly designed for 20-position configurations with 180-degree cable exit and shielding. This component functions as a protective and organizing element for D-Sub connector systems, providing mechanical support and electromagnetic shielding for signal integrity.

The main part 223249 carries an obsolete product status, indicating it is no longer in active production or supported by the manufacturer. This obsolescence necessitates identification of functionally equivalent substitute components to maintain system compatibility and ensure continued availability for repair, maintenance, and new assembly applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity Erni 223249 is determined by strict equivalence across the following critical parameters:

Position Count: The substitute must accommodate exactly 20 positions to ensure mechanical and electrical compatibility with existing D-Sub connector systems.

Cable Exit Configuration: The 180-degree cable exit angle is a fundamental mechanical requirement. Substitutes must provide identical cable routing geometry to fit within existing enclosure and cable management designs.

Shielding Requirement: The shielded designation indicates electromagnetic protection is integral to the application. Substitute components must maintain shielded construction to preserve signal integrity and EMI/RFI performance.

Connector Type: Both the main part and substitute are D-Sub backshell assemblies, confirming functional category equivalence.

The substitute part TE Connectivity AMP Connectors 5749190-1 satisfies all four critical parameters, establishing it as a direct functional equivalent for the obsolete 223249.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: TE Connectivity AMP Connectors 5749190-1 is the appropriate selection. This part carries active product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory requirements including RoHS compliance and EAR99 export classification.

For Maintenance and Repair of Existing Systems: Either the original TE Connectivity Erni 223249 or the substitute TE Connectivity AMP 5749190-1 may be applied, provided the system design accommodates the substitute's specified material composition (Metal, Zinc with Nickel over Copper plating) and compliance certifications.

Compliance Considerations: The substitute part 5749190-1 provides documented RoHS compliance and defined ECCN classification (EAR99), supporting regulatory documentation requirements for systems subject to environmental and export control standards.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity AMP 5749190-1 directly replace TE Connectivity Erni 223249 in existing assemblies?

A: Yes. Both parts are 20-position D-Sub backshell connectors with 180-degree cable exit and shielded construction. The mechanical and electrical parameters are equivalent, supporting direct substitution in existing designs.

Q: What is the significance of the obsolete status for part 223249?

A: Obsolete status indicates the manufacturer has discontinued production and support. While existing inventory remains available, long-term availability cannot be assured. The active-status substitute 5749190-1 provides continuity for future procurement requirements.

Q: Are there material or plating differences between the two parts?

A: The substitute part 5749190-1 specifies Metal construction with Nickel over Copper plating. The original part 223249 does not provide material specifications in available documentation. Both parts function as shielded backshells for 20-position D-Sub connectors.

Q: Does the substitute part meet environmental compliance standards?

A: TE Connectivity AMP 5749190-1 is RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), supporting deployment in applications subject to environmental and reliability standards.

Q: What is the AMPLIMITE .050 III series designation on the substitute part?

A: This designates the connector series family for the substitute part. It identifies the mechanical and electrical specifications within TE Connectivity's product line. Compatibility with 20-position D-Sub systems is maintained.
