Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 747959-1 D-Sub connector housing is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle for female contacts
• Number of positions: 50
• Number of rows: 3
• Shell size and layout: 5 (DD, D)
• Contact type: Signal
• Mounting type: Free hanging (in-line)
• Flange feature: Cable side (4-40)
• Features: Backshell and shielded configuration
• Shell material and finish: Steel, tin plated
• Dielectric material: Polyamide (PA), nylon
• Color: Black
• Series: AMPLIMITE HDP-20

Parts meeting all these parameters are classified as direct functional equivalents and may be substituted without modification to mating interfaces, mounting hardware, or electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5747959-1

The 5747959-1 is the direct functional equivalent to the obsolete 747959-1. Both parts share identical mechanical and electrical specifications across all critical parameters including connector style, position count, shell size, mounting configuration, and shielding features.

Compliance Advantages:

The 5747959-1 carries active product status, ensuring ongoing manufacturer support and supply chain availability. This part is RoHS compliant, whereas the 747959-1 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the 5747959-1 satisfies these requirements.

Material Specification:

The 5747959-1 specifies glass-filled polyamide (PA) for the dielectric material, compared to standard polyamide (PA) nylon in the 747959-1. This material enhancement provides improved mechanical and thermal properties while maintaining full dimensional and functional compatibility.

Shell Finish Specification:

The 5747959-1 provides explicit shell finish thickness specification of 200µin (5.08µm), whereas the 747959-1 does not specify this parameter. Both parts utilize steel with tin plating, ensuring equivalent corrosion resistance and electrical performance.

Inventory and Availability:

The 5747959-1 is available in active inventory with 1,650 pieces in stock, providing immediate procurement capability for new designs and field replacements.

Frequently Asked Questions (FAQ)

Q: Can the 5747959-1 be used as a direct replacement for the 747959-1 in existing assemblies?

A: Yes. The 5747959-1 meets all mechanical and electrical specifications required for direct substitution. Mating interfaces, mounting hardware, and contact compatibility remain unchanged. No design modifications are required.

Q: What is the significance of the glass-filled polyamide material in the 5747959-1?

A: Glass-filled polyamide provides enhanced mechanical strength and thermal stability compared to standard polyamide. This material upgrade does not affect connector dimensions, contact interfaces, or electrical performance. It represents an improvement in material specification while maintaining full compatibility.

Q: Does the RoHS compliance difference between these parts affect substitution?

A: RoHS compliance status is a regulatory and procurement consideration rather than a functional compatibility issue. If your application or supply chain requires RoHS-compliant components, the 5747959-1 satisfies this requirement. The 747959-1, being RoHS non-compliant, may not be acceptable for new designs or regulated applications.

Q: Are contacts included with either housing part?

A: No. Both the 747959-1 and 5747959-1 are housing-only components. Contacts must be procured separately and inserted into the housing during assembly.

Q: What packaging options are available for the substitute part?

A: The 5747959-1 is supplied in bulk packaging. The 747959-1 packaging specification is not provided in the available data.

Q: Can I use the 5747959-1 in applications originally designed for the 747959-1?

A: Yes. The 5747959-1 is functionally and mechanically equivalent across all specified parameters. It is suitable for direct substitution in any application utilizing the 747959-1 housing.

Q: What is the base product number relationship between these parts?

A: The 747959-1 has base product number 747959, while the 5747959-1 has base product number 5747959. The numeric prefix difference reflects the product line evolution from obsolete to active status within the AMPLIMITE HDP-20 series.
