Key Parameters

Substitute Part Grouping Explanation

Substitution of the 747459-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for connector style, position count, shell size, mounting configuration, termination method, contact materials, and performance ratings.

The primary substitution criterion is functional and dimensional compatibility: the substitute connector must interface with existing mating connectors and printed circuit board layouts without modification. Secondary criteria include compliance certifications, contact finish specifications, and operating environmental ratings.

The following key parameters establish substitution validity:

• Connector style and type (D-Sub receptacle, female sockets)
• Position count and row configuration (9 positions, 2 rows)
• Shell size and layout designation (Size 1, DE/E configuration)
• Mounting type and orientation (through-hole, right-angle)
• Termination method (solder)
• Electrical ratings (6A current, 125V voltage)
• Operating temperature range (-55°C to 105°C)
• Contact material and finish (phosphor bronze, gold flash)
• Flange configuration (4-40 housing/shell)

Parameter Comparison

Engineering Selection Recommendations

The 5747459-3 is a direct functional equivalent to the 747459-3 across all electrical, mechanical, and dimensional specifications. Both connectors share identical pin configurations, contact ratings, operating parameters, and physical mounting characteristics.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 747459-3 is classified as obsolete and carries RoHS non-compliant status. The 5747459-3 maintains active product status and achieves RoHS compliance, indicating alignment with current environmental and regulatory requirements.

For new designs and ongoing production requiring this connector configuration, the 5747459-3 is the appropriate selection. For legacy system maintenance where the original 747459-3 specification must be preserved, the 5747459-3 provides full functional compatibility while offering improved compliance posture and assured supply availability.

The packaging difference (tray for 5747459-3 versus unspecified for 747459-3) does not affect electrical or mechanical performance and relates only to logistics and handling procedures.

Frequently Asked Questions (FAQ)

Q: Are the 747459-3 and 5747459-3 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 6A current rating, 125V voltage rating, gold-plated phosphor bronze contacts, and operating temperature range of -55°C to 105°C. They are fully electrically interchangeable.

Q: Are the 747459-3 and 5747459-3 mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications: 9-position D-Sub receptacle configuration, Size 1 (DE/E) shell, right-angle through-hole mounting, 0.590" (14.99mm) backset spacing, and 4-40 housing/shell flange. They are fully mechanically interchangeable without modification to PCB layouts or mating connector interfaces.

Q: What is the significance of the product status difference?

A: The 747459-3 is classified as obsolete, indicating TE Connectivity no longer manufactures or supports this part number. The 5747459-3 maintains active product status, ensuring continued manufacturing, technical support, and supply chain availability. For ongoing production and field service, the active part number is the appropriate selection.

Q: How does RoHS compliance affect substitution?

A: The 747459-3 is RoHS non-compliant, while the 5747459-3 is RoHS compliant. RoHS compliance indicates the substitute part meets restrictions on hazardous substances. For applications subject to RoHS requirements or for organizations implementing RoHS-compliant supply chains, the 5747459-3 is the required selection.

Q: Does packaging affect connector performance?

A: No. The packaging difference (tray for 5747459-3) does not affect electrical performance, mechanical fit, or contact characteristics. Packaging relates only to order quantities, handling procedures, and logistics. The connector itself is identical.

Q: Can the 5747459-3 be used as a direct replacement in existing assemblies?

A: Yes. The 5747459-3 provides direct replacement capability for the 747459-3 in all applications. No circuit modifications, PCB layout changes, or mating connector adjustments are required. The substitute part maintains full compatibility with existing designs.

Q: What inventory considerations apply to these part numbers?

A: The 747459-3 shows 883 pieces in stock as new original inventory. The 5747459-3 shows 1534 pieces in stock. For new procurement, the 5747459-3 offers greater availability and active product support. Existing 747459-3 inventory may be utilized for legacy system maintenance.
