Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 747052-3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Connector Architecture: Connector style (D-Sub), type (receptacle with female sockets), position count (15), row configuration (2), and shell size/layout (2, DA, A) must be identical.

Termination Compatibility: The IDC ribbon cable termination method and wire gauge compatibility (26-28 AWG, stranded or solid) ensure direct mechanical and electrical compatibility with existing cable assemblies.

Electrical Performance: Current rating (1.25A), contact material (phosphor bronze), contact finish (gold at 30.0µin thickness), and operating temperature range (-55°C ~ 105°C) must be maintained.

Physical Integration: Mounting type (free hanging, in-line), flange feature (housing/shell with 4-40 fastening), and shell material/finish (steel, tin plated) ensure mechanical fit and durability.

Regulatory Compliance: Material flammability rating (UL94 V-0) and moisture sensitivity level (MSL 1, unlimited) must be preserved.

The substitute part 1658610-3 meets all these criteria while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658610-3 is the direct functional equivalent of the obsolete 747052-3. Both connectors are members of the AMPLIMITE HDF-20 series and maintain identical electrical, mechanical, and thermal specifications across all critical parameters.

Product Status Advantage: The 1658610-3 holds active product status, ensuring continued availability, manufacturing support, and supply chain reliability. The 747052-3 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: The 1658610-3 is ROHS3 compliant and has defined REACH status, whereas the 747052-3 is RoHS non-compliant with undefined REACH status. For applications subject to environmental regulations or customer compliance requirements, the 1658610-3 provides superior regulatory alignment.

Packaging and Inventory: The 1658610-3 is supplied in bulk packaging with 2166 units in stock, compared to 1086 units of the 747052-3. Bulk packaging reduces per-unit cost and supports higher-volume production requirements.

Direct Substitution: All electrical performance parameters, mechanical dimensions, and termination methods are identical. The 1658610-3 integrates directly into existing designs without modification to cable assemblies, PCB layouts, or connector mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 1658610-3 directly replace the 747052-3 in existing applications?

A: Yes. The 1658610-3 is a direct functional equivalent with identical connector architecture, electrical ratings, mechanical dimensions, and IDC ribbon cable termination compatibility. No design modifications are required.

Q: Are the wire gauge specifications compatible between the two parts?

A: Yes. The 1658610-3 explicitly supports 26-28 AWG wire in both stranded and solid configurations, which is the standard wire gauge range for IDC ribbon cable assemblies used with 15-position D-Sub connectors. The 747052-3 does not specify wire gauge, but operates within the same IDC termination standard.

Q: What is the difference in packaging between these parts?

A: The 747052-3 packaging type is not specified in the documentation. The 1658610-3 is supplied in bulk packaging, which typically offers cost advantages for production quantities and simplifies inventory management.

Q: Does the 1658610-3 meet RoHS requirements?

A: Yes. The 1658610-3 is ROHS3 compliant. The 747052-3 is RoHS non-compliant. For applications requiring RoHS compliance, the 1658610-3 is the appropriate selection.

Q: Are the operating temperature ranges identical?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 105°C, ensuring thermal performance equivalence in all environmental conditions.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 1.25A per contact. This rating applies to signal-type contacts and is consistent with standard D-Sub connector specifications for this shell size and contact configuration.

Q: Is the contact finish specification the same?

A: Yes. Both connectors feature gold-plated contacts with a thickness of 30.0µin (0.76µm) over phosphor bronze base material. This ensures identical electrical performance and corrosion resistance.

Q: Can these connectors be used interchangeably in ribbon cable assemblies?

A: Yes. Both connectors use IDC (insulation displacement contact) termination for ribbon cable. The identical shell size, position count, row configuration, and flange design ensure mechanical and electrical compatibility with the same ribbon cable assemblies.

Q: What is the shell size designation, and why is it important?

A: Both connectors use shell size 2 with DA, A layout designation. This standardized designation ensures compatibility with mating plugs, cable assemblies, and mounting hardware designed for this specific D-Sub configuration.

Q: Are there any differences in the dielectric material?

A: No. Both connectors use thermoplastic dielectric material with identical UL94 V-0 flammability rating, ensuring equivalent electrical insulation and fire safety performance.
