Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658610-2 is the direct functional equivalent of the 747052-2 and serves as the primary substitute for this obsolete connector. Selection of the 1658610-2 is based on the following engineering criteria:

Product Status Alignment: The 1658610-2 maintains active product status, ensuring continued availability and manufacturer support. The 747052-2 is classified as obsolete, creating supply chain risk for new designs and system maintenance.

Regulatory Compliance: The 1658610-2 achieves ROHS3 compliance, whereas the 747052-2 is non-compliant. For applications subject to RoHS directives, the 1658610-2 is the appropriate selection. The 1658610-2 also provides defined REACH status (REACH Affected), eliminating vendor uncertainty present in the 747052-2 specification.

Electrical and Mechanical Equivalence: All critical electrical parameters (current rating, contact material, contact finish, operating temperature) and mechanical parameters (shell size, mounting type, termination method, flange configuration) are identical between the two parts. Direct substitution is supported without circuit or mechanical redesign.

Inventory and Packaging: The 1658610-2 is available in bulk packaging with higher inventory levels (2112 pieces) compared to the 747052-2 (1089 pieces), supporting both prototype and production procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can the 1658610-2 be used as a direct replacement for the 747052-2 in existing designs?

A: Yes. The 1658610-2 is electrically and mechanically equivalent to the 747052-2. All connector specifications, including pin count, shell size, termination method, current rating, and operating temperature range, are identical. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the 747052-2?

A: The 747052-2 is classified as obsolete, creating supply chain discontinuity. The 1658610-2 is an active product offering equivalent functionality with improved regulatory compliance (ROHS3 compliant versus non-compliant) and defined REACH status.

Q: Are there differences in the ribbon cable compatibility between these parts?

A: Both parts use IDC (Insulation Displacement Contact) termination for ribbon cable. The 1658610-2 specifies compatible wire gauge as 26-28 AWG, stranded or solid. The 747052-2 does not specify wire gauge in its documentation. Ribbon cables meeting 26-28 AWG specification are compatible with both connectors.

Q: What is the difference in packaging between the 747052-2 and 1658610-2?

A: The 747052-2 packaging is not specified in the available documentation. The 1658610-2 is supplied in bulk packaging, which is standard for production and high-volume applications.

Q: Are there any compliance differences that affect application suitability?

A: The 1658610-2 is ROHS3 compliant and has defined REACH status (REACH Affected). The 747052-2 is RoHS non-compliant with undefined REACH status. For applications in regulated industries or regions with RoHS/REACH requirements, the 1658610-2 is the appropriate selection.

Q: Do both connectors support the same current and voltage specifications?

A: Both connectors are rated for 1.25A continuous current. Voltage rating is not specified for either part in the provided documentation. Both operate across the identical temperature range of -55°C to 105°C.

Q: What is the contact finish specification for both parts?

A: Both the 747052-2 and 1658610-2 feature gold-plated contacts with a thickness of 30.0µin (0.76µm) over phosphor bronze contact material. Contact finish is identical between the two parts.

Q: Can the 1658610-2 be used in applications originally designed for the 747052-2?

A: Yes. The 1658610-2 maintains all electrical and mechanical specifications of the 747052-2. Existing circuit designs, mechanical assemblies, and ribbon cable configurations are fully compatible with the 1658610-2 without modification.
