TE Connectivity 5745908-2 D-Sub Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5745908-2 is an AMPLIMITE HDP-20 series D-Sub connector plug housing designed for male contacts in a 15-position, 2-row configuration. This component functions as the housing shell for D-Sub connectors used in signal transmission applications. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the connector housing meets the same dimensional, material, and performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5745908-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Plug for Male Contacts
• Number of Positions: 15
• Number of Rows: 2
• Shell Size, Connector Layout: 2 (DA, A)
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Cable Side (4-40)
• Features: Grounding Indents
• Shell Material, Finish: Steel, Tin Plated
• Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The Amphenol CONEC DSS2XPXXG04X meets all mandatory matching parameters and qualifies as a direct substitute. Variations in shell finish thickness, dielectric material composition, ingress protection rating, operating temperature range, and mating cycle specifications do not preclude substitution when the core mechanical and electrical interface requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol CONEC DSS2XPXXG04X qualifies as a direct substitute for the TE Connectivity 5745908-2 based on complete alignment of all mandatory mechanical and electrical interface parameters. Both components are Active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compatibility in applications requiring these standards.

The substitute part provides additional specifications not declared in the original part: IP20 ingress protection rating, operating temperature range of -55°C to 125°C, and 50 mating cycles. These additional specifications represent enhanced or defined performance characteristics that do not conflict with the original design requirements.

The dielectric material difference (Thermoplastic versus Polybutylene Terephthalate with glass filling) and increased shell finish thickness (315µin versus 200µin) in the substitute part represent material and process variations that maintain functional equivalence for D-Sub connector housing applications. Both materials provide adequate insulation and mechanical support for the 15-position, 2-row configuration with grounding indents.

Selection between the original and substitute part should be based on availability, lead time, packaging format (Bulk versus Box), and inventory requirements rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol CONEC DSS2XPXXG04X be used as a direct replacement for the TE Connectivity 5745908-2?

A: Yes. Both components share identical connector style, type, position count, row configuration, shell size layout, contact type, mounting method, flange specification, grounding features, shell material finish, color, and regulatory compliance status. These parameters define mechanical and electrical interface compatibility for D-Sub connector housings.

Q: What is the significance of the different dielectric materials?

A: The original part specifies Thermoplastic dielectric material, while the substitute uses Polybutylene Terephthalate (PBT) with glass filling. Both materials function as insulators in D-Sub connector housings. The glass-filled PBT in the substitute part provides enhanced mechanical rigidity and thermal stability. This material difference does not affect the connector's ability to house 15 male contacts in a 2-row configuration or maintain the required electrical isolation.

Q: Why does the substitute part have a thicker tin plating?

A: The Amphenol CONEC DSS2XPXXG04X specifies 315µin (8.00µm) shell finish thickness compared to 200µin (5.08µm) for the original part. Increased plating thickness provides enhanced corrosion resistance and extended contact durability. This represents an improvement in environmental protection without affecting the connector's core functionality or mating interface.

Q: Are there packaging differences between these parts?

A: Yes. The TE Connectivity 5745908-2 is supplied in Bulk packaging, while the Amphenol CONEC DSS2XPXXG04X is supplied in Box packaging. Packaging format affects storage, handling, and inventory management but does not influence technical compatibility or performance.

Q: What does the additional IP20 rating on the substitute part mean?

A: IP20 ingress protection rating indicates the substitute part provides protection against solid objects larger than 12mm and is not protected against liquid ingress. The original part does not specify an ingress protection rating. The IP20 specification on the substitute represents a defined environmental protection level that does not conflict with applications using the original part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TE Connectivity 5745908-2 and Amphenol CONEC DSS2XPXXG04X are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What is the significance of the different mating cycle specifications?

A: The original part does not specify mating cycles, while the substitute part is rated for 50 mating cycles. Mating cycles define the number of times a connector can be mated and unmated before performance degradation. The specified 50 cycles for the substitute part represents a defined mechanical durability characteristic. Applications requiring higher cycle counts should reference the specific use case requirements.

Q: Can I mix components from both manufacturers in the same assembly?

A: Yes. Both the TE Connectivity 5745908-2 and Amphenol CONEC DSS2XPXXG04X are 15-position D-Sub plug housings with identical mechanical interfaces. They can be used interchangeably in applications where the connector housing specifications match the design requirements. However, maintaining consistency with a single manufacturer source within a production batch is a standard quality practice.
