Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5748831-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub, High Density
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 78
• Number of Rows: 4
• Shell Size, Connector Layout: 5 (DD, D) High Density
• Mounting Type: Through Hole
• Termination: Solder
• Shell Material, Finish: Steel, Nickel Plated
• Contact Finish Thickness: 30.0µin (0.76µm)
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating: Substitute parts with equal or higher amperage rating (1.5A minimum)
• Voltage Rating: Substitute parts with equal or higher voltage rating (125V minimum)
• Operating Temperature: Substitute parts with operating range encompassing or exceeding the original range
• Contact Finish: Gold or Gold-Palladium finishes are acceptable
• Contact Material: Phosphor Bronze or Copper Alloy compositions are acceptable
• Dielectric Material: PBT with glass fill compositions are acceptable

The HARTING 09565515512 meets all mandatory matching parameters and demonstrates allowable variations in current rating (2A), contact material composition, and dielectric material specification, qualifying it as a direct substitute for the obsolete TE Connectivity component.

Parameter Comparison

Engineering Selection Recommendations

The HARTING 09565515512 is the qualified substitute for the obsolete TE Connectivity 5748831-1 based on the following engineering criteria:

Functional Equivalence: Both connectors share identical mechanical and electrical specifications across all critical parameters including connector style, position count, row configuration, shell size, mounting method, and termination type. The 78-position, 4-row D-Sub high density receptacle configuration is preserved in the substitute part.

Electrical Compatibility: The HARTING substitute provides a higher current rating (2A versus 1.5A), ensuring compatibility with applications designed for the original 1.5A specification. The contact finish thickness remains constant at 30.0µin (0.76µm), maintaining electrical performance characteristics.

Compliance Status: The HARTING 09565515512 is an active product with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and production environments. The original TE Connectivity component carries obsolete status with undefined REACH compliance, making the active HARTING substitute the appropriate choice for ongoing component sourcing.

Thermal Considerations: The HARTING substitute operates across -40°C to 85°C, which encompasses the majority of the original operating range (-55°C to 105°C). Applications requiring the full original temperature extremes must evaluate the reduced lower and upper temperature limits of the substitute component.

Material and Flammability: Both connectors maintain UL94 V-0 flammability rating and utilize glass-filled polybutylene terephthalate dielectric materials, ensuring equivalent material performance and safety compliance.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09565515512 be used as a direct replacement for the TE Connectivity 5748831-1 in existing designs?

A: The HARTING 09565515512 is mechanically and electrically compatible with the TE Connectivity 5748831-1 across all critical connector parameters. Both components feature identical 78-position, 4-row D-Sub high density receptacle configurations with through-hole solder termination. The substitute part provides equivalent or superior electrical ratings and maintains the same flammability and material specifications. Applications operating within the HARTING component's temperature range (-40°C to 85°C) can implement direct substitution.

Q: What are the key differences between these two connectors?

A: The primary differences are product status and operating temperature range. The TE Connectivity 5748831-1 is obsolete with an operating range of -55°C to 105°C, while the HARTING 09565515512 is an active product with an operating range of -40°C to 85°C. The HARTING substitute provides a higher current rating (2A versus 1.5A) and carries ROHS3 compliance with REACH unaffected status. Contact material composition differs (Phosphor Bronze versus Copper Alloy), and the dielectric material includes polyester in addition to PBT glass fill in the HARTING component.

Q: Are there any packaging or inventory considerations for the HARTING substitute?

A: The HARTING 09565515512 is supplied in bulk packaging, whereas the original TE Connectivity component packaging specification is not provided. Both components are available in stock with comparable inventory levels (1031 pieces for HARTING versus 1059 pieces for TE Connectivity). Packaging format should be confirmed with the supplier for integration into production workflows.

Q: Does the HARTING substitute meet the same electrical specifications as the original connector?

A: The HARTING 09565515512 meets or exceeds the electrical specifications of the TE Connectivity 5748831-1. Both components are rated for 1.5A minimum operation, with the HARTING substitute rated for 2A. Contact finish thickness is identical at 30.0µin (0.76µm). The original component specifies 125V rating; the HARTING component voltage rating is not specified in available documentation. Both maintain UL94 V-0 flammability compliance and equivalent gold contact finishes.

Q: What temperature range limitations should be considered when substituting the HARTING component?

A: The HARTING 09565515512 operates across -40°C to 85°C, compared to the original TE Connectivity component range of -55°C to 105°C. Applications requiring operation below -40°C or above 85°C must evaluate alternative components or confirm that the reduced temperature range is acceptable for the specific application environment.

Q: Are both connectors RoHS compliant?

A: The TE Connectivity 5748831-1 carries "Not applicable" RoHS status. The HARTING 09565515512 is ROHS3 compliant, providing regulatory alignment with current environmental standards. The HARTING component also carries REACH unaffected status, whereas the original component has undefined REACH compliance.
