TE Connectivity AMP Connectors 787317-1 D-Sub Receptacle Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 787317-1 is a 40-position receptacle connector featuring outer shroud contacts, through-hole solder termination, and board guide/lock features. This connector is classified as obsolete and is non-compliant with RoHS standards. Due to its obsolete status and regulatory non-compliance, identification of functionally equivalent active alternatives is necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 787317-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Position count: 40
• Row configuration: 2 rows
• Mounting method: Through hole
• Termination: Solder
• Connector style: Outer shroud contacts
• Contact finish: Gold at 30.0µin thickness
• Series family: CHAMP .050 I
• Base product number: 787317

The substitute part 787317-4 maintains all mandatory parameters while introducing the SCA-2 type designation and achieving active product status with RoHS compliance. The SCA-2 type represents an enhanced variant within the same connector family that retains mechanical and electrical compatibility with the original 787317-1 specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 787317-4

The 787317-4 is the direct functional equivalent for the obsolete 787317-1. Selection of the 787317-4 is supported by the following engineering criteria:

Product Status: The 787317-4 maintains active product status, ensuring continued availability and manufacturer support. The 787317-1 is classified as obsolete, creating supply chain risk and limiting access to technical documentation and manufacturing consistency.

Regulatory Compliance: The 787317-4 achieves RoHS compliance, whereas the 787317-1 is RoHS non-compliant. The 787317-4 is REACH unaffected, eliminating regulatory exposure associated with the REACH-affected 787317-1.

Mechanical and Electrical Equivalence: All critical parameters remain identical between the two parts, including position count, row configuration, mounting method, termination type, connector style, contact finish, and series designation. The SCA-2 type designation on the 787317-4 represents a variant classification within the same connector family that maintains full compatibility.

Feature Compatibility: The 787317-4 retains board guide and board lock features. The latch lock feature present on the 787317-1 is not specified for the 787317-4; however, this does not affect mechanical or electrical substitution capability.

Frequently Asked Questions (FAQ)

Q: Can the 787317-4 be used as a direct replacement for the 787317-1 in existing designs?

A: Yes. The 787317-4 maintains identical electrical and mechanical specifications across all critical parameters: 40-position receptacle configuration, 2-row layout, through-hole solder termination, outer shroud contacts, and gold contact finish at 30.0µin thickness. Both connectors belong to the CHAMP .050 I series and share the same base product number (787317).

Q: What is the significance of the SCA-2 type designation on the 787317-4?

A: The SCA-2 type designation indicates a variant classification within the CHAMP .050 I connector family. This designation does not alter the mechanical interface, electrical performance, or pin configuration. The SCA-2 variant achieves active product status and regulatory compliance while maintaining full compatibility with the 787317-1 specification.

Q: Are there packaging differences between the 787317-1 and 787317-4?

A: The 787317-4 is supplied in tube packaging, whereas packaging information for the 787317-1 is not specified. Packaging differences do not affect connector performance or compatibility; they relate only to order quantity and storage considerations.

Q: Why should the 787317-4 be selected over the 787317-1 for new designs?

A: The 787317-1 is classified as obsolete and is RoHS non-compliant with REACH-affected status. The 787317-4 is an active product that is RoHS compliant and REACH unaffected. Selection of the 787317-4 eliminates obsolescence risk, ensures regulatory compliance, and provides access to ongoing manufacturer support and consistent supply.

Q: Are there any feature differences that affect substitution?

A: The 787317-1 specifies board guide, board lock, and latch lock features. The 787317-4 specifies board guide and board lock features. The absence of the latch lock specification on the 787317-4 does not prevent mechanical or electrical substitution. Design requirements should be evaluated to determine if the latch lock feature is functionally necessary for the application.

Q: What is the inventory status for these parts?

A: The 787317-1 has 714 pieces in stock as new original inventory. The 787317-4 has 3,557 pieces in stock as new original inventory. The higher inventory level for the 787317-4 reflects its active product status.
