Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 747960-1 is determined by strict equivalence across all mechanical and electrical parameters that define connector interchangeability. The substitute part must maintain identical specifications in the following critical areas:

Mechanical Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Plug for Male Contacts)
• Position count (50 positions)
• Row configuration (3 rows)
• Shell size and layout (5 DD, D)
• Mounting type (Free Hanging In-Line)
• Flange feature and fastener specification (Cable Side 4-40)

Material and Construction Parameters:

• Shell material and finish type (Steel, Tin Plated)
• Dielectric material composition (Polyamide PA, Nylon, Glass Filled)
• Feature set (Backshell, Grounding Indents, Shielded)
• Color specification (Black)

Functional Parameters:

• Contact type (Signal)
• Series designation (AMPLIMITE HDP-20)

The substitute part 1658661-1 meets all these criteria, providing direct functional and mechanical equivalence while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658661-1 serves as the direct equivalent substitute for the obsolete 747960-1 connector housing. Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector geometry, contact configuration, material composition, and feature set.

Selection Basis:

The 1658661-1 is recommended for new designs and component replacement applications based on the following factors:

Product Status: The substitute part maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain reliability. The main part 747960-1 is classified as obsolete, limiting future procurement options.

Regulatory Compliance: The 1658661-1 achieves RoHS compliance, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. The main part does not meet this compliance standard.

Specification Completeness: The substitute part provides documented shell finish thickness specification (200µin / 5.08µm), offering enhanced technical documentation compared to the main part.

Functional Equivalence: All mechanical, electrical, and material parameters remain identical between the two parts, ensuring direct interchangeability in existing connector assemblies and new applications.

Frequently Asked Questions (FAQ)

Q: Can the 1658661-1 be used as a direct replacement for the 747960-1 in existing assemblies?

A: Yes. The 1658661-1 maintains identical specifications across all mechanical and electrical parameters including connector style, position count, shell size, mounting type, material composition, and feature set. Direct substitution is supported without modification to mating components or assembly procedures.

Q: What is the primary reason for substituting the 747960-1?

A: The 747960-1 is classified as obsolete, which restricts long-term availability and manufacturer support. The 1658661-1 is an active product offering equivalent functionality with improved supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The 1658661-1 is RoHS compliant, while the 747960-1 is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the 1658661-1 is the appropriate selection.

Q: Do these parts have different packaging options?

A: The 747960-1 packaging is not specified in available documentation. The 1658661-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the shell finish specifications identical?

A: The 747960-1 does not provide documented shell finish thickness. The 1658661-1 specifies 200µin (5.08µm) tin plating thickness. Both parts use steel with tin plating as the shell material and finish.

Q: What is the contact configuration for these housings?

A: Both parts are housings designed for male contacts and do not include contacts. Contacts must be procured separately and are compatible with the AMPLIMITE HDP-20 series 50-position connector system.

Q: Are these parts suitable for signal transmission applications?

A: Yes. Both parts are classified as signal contact type connectors and are designed for signal transmission within the AMPLIMITE HDP-20 series connector system.

Q: What mounting configuration do these connectors support?

A: Both parts support free hanging in-line mounting with cable-side flange featuring 4-40 fastener specification.
