Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 747943-1 is based on electrical and mechanical parameter equivalence within the D-Sub connector category. The substitute part 1-747943-5 maintains identical specifications across all critical functional parameters: 9-position receptacle configuration, DE/E shell size, female socket contact type, IDC and discrete wire termination capability, cable-side male jackscrew flange, steel tin-plated shell with gold-plated contacts, 250V voltage rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability compliance.

The key parameters determining substitution eligibility are:

• Connector style and type (D-Sub receptacle, female sockets)
• Position count and row configuration (9 positions, 2 rows)
• Shell size and layout (Size 1, DE/E)
• Termination method (IDC, discrete wire)
• Flange configuration (cable-side male jackscrew 4-40)
• Electrical ratings (250V, wire gauge 26-30 AWG)
• Environmental specifications (temperature range, flammability rating)

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-747943-5 is the direct equivalent for the obsolete 747943-1. Both parts are manufactured by TE Connectivity within the same AMPLIMITE HDE-20 series and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance.

The 1-747943-5 is classified as active, ensuring continued availability and manufacturing support. Additionally, the 1-747943-5 carries RoHS compliance certification, whereas the 747943-1 is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance with modern environmental regulations, the 1-747943-5 is the appropriate selection.

Both parts maintain equivalent performance across all functional parameters including connector geometry, electrical ratings, termination methods, and environmental operating specifications. The substitution is direct and does not require circuit or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1-747943-5 be used as a direct replacement for the 747943-1?

A: Yes. The 1-747943-5 is electrically and mechanically equivalent to the 747943-1. All functional parameters, including connector type, position count, shell size, termination method, electrical ratings, and operating temperature range, are identical. The parts are interchangeable in applications where the 747943-1 was originally specified.

Q: What is the primary reason to transition from 747943-1 to 1-747943-5?

A: The 747943-1 is classified as obsolete, which creates supply chain risk for new production and field service. The 1-747943-5 is an active product with confirmed manufacturing continuity. Additionally, the 1-747943-5 is RoHS compliant, whereas the 747943-1 is not, making it suitable for applications subject to environmental regulations.

Q: Are there packaging differences between these parts?

A: The 747943-1 packaging specification is not provided in the technical data. The 1-747943-5 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Do both parts support the same termination methods?

A: Yes. Both the 747943-1 and 1-747943-5 support IDC (insulation displacement contact) and discrete wire termination. Wire gauge compatibility is 26-30 AWG for both parts.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 250V operation and support current ratings that vary by wire gauge. Operating temperature range is -55°C to 105°C for both parts. Contact finish specifications, including gold plating at 30.0µin thickness, are identical.

Q: What is the significance of the RoHS compliance difference?

A: The 1-747943-5 is RoHS compliant, meaning it meets restrictions on hazardous substances in electrical and electronic equipment. The 747943-1 is RoHS non-compliant. For applications in regulated industries or regions with RoHS requirements, the 1-747943-5 is the required selection.

Q: Are the connector dimensions and mounting configurations the same?

A: Yes. Both parts feature identical D-Sub Size 1 (DE/E) shell configuration, 9-position 2-row layout, cable-side male jackscrew flange (4-40), and free-hanging in-line mounting type. Physical compatibility is complete.
