TE Connectivity 745134-1 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745134-1 is a 25-position hinged backshell connector from the AMPLIMITE HD-20 series, designed for D-Sub applications with 90° and 180° cable exit configurations. This component is classified as an accessory backshell for D-Sub connectors and features unshielded, thermoplastic construction with gray coloring.

The 745134-1 carries an obsolete product status, which necessitates identification of active equivalent parts for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility with existing connector assemblies and cable configurations.

Critical Substitution Parameters:

• Number of Positions: 25
• Compatible Shell Size: B
• Compatible D-Sub Size: 25pos and HD44pos
• Cable Exit Angle: 90°, 180°
• Cable Type: Round
• Shielding: Unshielded
• Primary Material: Thermoplastic
• Color: Gray
• Hardware Features: Mating Screws 4-40
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5745134-1 meets all specified parameters and maintains full compatibility with applications designed for the 745134-1. The primary distinction between these parts is product status and RoHS compliance classification, with the substitute representing an active product line offering.

Parameter Comparison

Engineering Selection Recommendations

The 5745134-1 serves as the direct functional equivalent to the obsolete 745134-1. Both parts are manufactured by TE Connectivity within the AMPLIMITE HD-20 series and maintain identical mechanical and electrical specifications for D-Sub backshell applications.

Product Status Consideration: The 745134-1 is classified as obsolete, while the 5745134-1 maintains active product status. For new designs and ongoing procurement, the 5745134-1 is the appropriate selection to ensure continued availability and manufacturer support.

Compliance Consideration: The 5745134-1 carries RoHS Compliant certification, whereas the 745134-1 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the 5745134-1. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Mechanical and Electrical Compatibility: All critical parameters determining connector compatibility remain identical between the two parts. The 5745134-1 provides direct substitution for the 745134-1 in all D-Sub 25-position applications requiring hinged backshell configurations with 90° and 180° cable exit options.

Frequently Asked Questions (FAQ)

Q: Can the 5745134-1 directly replace the 745134-1 in existing assemblies?

A: Yes. The 5745134-1 maintains identical specifications across all mechanical and electrical parameters, including position count, shell size, cable exit angles, material composition, and hardware features. Direct substitution is supported without modification to existing connector assemblies or cable configurations.

Q: What is the primary reason for substituting the 745134-1?

A: The 745134-1 carries an obsolete product status, making it unavailable for new procurement. The 5745134-1 is an active product offering from the same manufacturer and series, providing continued availability and manufacturer support.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The 745134-1 is RoHS non-compliant, while the 5745134-1 is RoHS Compliant. Applications subject to RoHS regulatory requirements must use the 5745134-1.

Q: Do both parts support the same cable exit configurations?

A: Yes. Both the 745134-1 and 5745134-1 support 90° and 180° cable exit angles with round cable types. No configuration changes are required when substituting between these parts.

Q: What is the compatible D-Sub connector size for these backshells?

A: Both parts are compatible with 25-position D-Sub connectors and HD44-position connectors. The shell size designation is B for both parts.

Q: Are the mating hardware specifications identical?

A: Yes. Both parts feature 4-40 mating screws as assembly hardware. No hardware modifications are necessary when performing substitution.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is packaging different between the 745134-1 and 5745134-1?
