Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connector housings is determined by strict alignment across mechanical and electrical parameters. The following criteria establish whether a part number qualifies as a direct equivalent or substitute:

Critical Matching Parameters:

• Connector style must remain D-Sub
• Connector type must be plug for male contacts
• Position count must equal 37
• Row configuration must equal 2
• Shell size and layout designation must match (4, DC, C)
• Mounting type must be free hanging (in-line)
• Flange feature must be cable side with 4-40 specification

Important Matching Parameters:

• Shell material and finish (steel, tin plated) must be identical
• Shielding feature must be present
• Dielectric material composition must be compatible with original specifications

Regulatory and Compliance Parameters:

• RoHS compliance status affects suitability for regulated markets
• REACH status determines applicability in European Union applications

The substitute part 5786929-1 satisfies all critical and important matching parameters while providing enhanced regulatory compliance through RoHS certification and REACH compliance status.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5786929-1

The 5786929-1 is the direct functional equivalent of the obsolete 786929-1 and is the appropriate selection for new designs and component replacement applications. This substitute maintains identical mechanical and electrical specifications across all critical parameters including connector style, position count, shell size, mounting configuration, and shielding characteristics.

Compliance Advantages:

The 5786929-1 provides enhanced regulatory compliance through RoHS certification, making it suitable for applications subject to European Union Restriction of Hazardous Substances regulations. The part carries active product status with defined REACH compliance, ensuring long-term availability and supply chain stability compared to the discontinued 786929-1.

Material and Construction Differences:

While the 786929-1 specifies thermoplastic dielectric material without further detail, the 5786929-1 uses polyamide (PA) nylon with glass reinforcement. This material composition provides improved mechanical strength and thermal stability while maintaining electrical insulation properties required for signal contact applications.

The 5786929-1 includes backshell and grounding indent features not explicitly listed for the 786929-1, providing enhanced shielding effectiveness and improved grounding contact surfaces. These features are compatible with the original connector design and do not introduce mechanical or electrical incompatibilities.

Inventory and Availability:

The 5786929-1 is available in bulk packaging with 1160 pieces in current stock, providing immediate procurement capability. The original 786929-1, while showing 1074 pieces in inventory, carries obsolete status and represents depleting stock with no future manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 5786929-1 directly replace the 786929-1 in existing assemblies?

A: Yes. The 5786929-1 maintains identical mechanical and electrical specifications across all critical parameters. The connector style, position count, shell size, mounting type, and flange configuration are identical. The substitute is mechanically and electrically compatible with existing contact sets and mating connectors designed for the 786929-1.

Q: What is the difference between the dielectric materials used in each part?

A: The 786929-1 uses thermoplastic material without specified composition. The 5786929-1 uses polyamide (PA) nylon with glass reinforcement, which is a specific thermoplastic formulation. Both materials function as electrical insulators for the connector housing. The glass-filled polyamide in the 5786929-1 provides enhanced mechanical strength and thermal stability while maintaining the same electrical insulation properties.

Q: Does the 5786929-1 include additional features that might affect compatibility?

A: The 5786929-1 includes backshell and grounding indent features in addition to the shielding present in the 786929-1. These features enhance electromagnetic shielding and grounding contact surfaces. They do not introduce mechanical or electrical incompatibilities with existing contact assemblies or mating connectors. The connector maintains the same overall form factor and mounting interface.

Q: What is the significance of RoHS compliance for the 5786929-1?

A: RoHS compliance indicates that the 5786929-1 meets European Union Restriction of Hazardous Substances regulations, which restrict the use of lead, cadmium, mercury, and other hazardous materials in electrical and electronic equipment. The 786929-1 is RoHS non-compliant. Organizations subject to RoHS requirements or serving regulated markets must use the 5786929-1 to maintain regulatory compliance.

Q: Are there packaging differences between the two part numbers?

A: The 786929-1 packaging is not specified in available documentation. The 5786929-1 is supplied in bulk packaging. Both part numbers are supplied without contacts included, requiring separate procurement of male contact elements compatible with the 37-position housing.

Q: What is the shell finish thickness specification for the 5786929-1?

A: The 5786929-1 specifies a tin plated shell finish with a thickness of 200 microinches (5.08 micrometers). The 786929-1 does not provide finish thickness specification. Both parts use steel with tin plating as the shell material and finish, providing equivalent corrosion resistance and electrical conductivity for shielding applications.

Q: Why is the 786929-1 listed as obsolete?

A: Obsolete product status indicates that TE Connectivity has discontinued active manufacturing and support for this part number. The 5786929-1 is the active replacement part in the AMPLIMITE HDP-20 series, ensuring continued availability and manufacturing support for future component requirements.

Q: Can the 5786929-1 be used in applications originally designed for the 786929-1?

A: Yes. The 5786929-1 is functionally equivalent across all critical mechanical and electrical parameters. Applications designed for the 786929-1 can use the 5786929-1 without design modifications. The substitute provides improved regulatory compliance and enhanced features while maintaining compatibility with existing contact assemblies and mating connectors.
