Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 745112-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle, Female Sockets)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Current rating (6A)
• Voltage rating (125V)
• Contact finish (Gold)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Shell material and finish (Steel, Tin Plated)
• Flange feature (Mating Side, Standard Screws 4-40)
• Backset spacing (0.545" / 13.84mm)

Environmental & Regulatory Parameters:

• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Dielectric material (Polyamide, Nylon, Glass Filled)

The substitute part 5745112-2 maintains full equivalence across all electrical, mechanical, and environmental parameters. The primary distinction is product status (obsolete versus active) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5745112-2

The 5745112-2 is a direct functional equivalent to the 745112-2 across all critical electrical, mechanical, and environmental parameters. Both connectors maintain identical specifications for connector type, position count, shell size, mounting configuration, current and voltage ratings, operating temperature range, and flammability certification.

Compliance Considerations:

The 5745112-2 offers improved regulatory compliance status. It is RoHS compliant and REACH unaffected, whereas the 745112-2 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to RoHS or REACH regulatory requirements, the 5745112-2 is the appropriate selection.

Contact Material Difference:

The 745112-2 uses copper alloy contacts, while the 5745112-2 uses phosphor bronze contacts. Both materials are suitable for the specified electrical parameters (6A at 125V) and maintain gold plating for signal integrity. This material difference does not affect functional compatibility in standard applications.

Product Status:

The 745112-2 is classified as obsolete, while the 5745112-2 is active. For new designs, production continuity, and long-term availability, the 5745112-2 is the recommended selection.

Packaging:

The 5745112-2 is supplied in tray packaging, which may differ from the original packaging of the 745112-2. Verify packaging requirements for your specific procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5745112-2 be used as a direct replacement for the 745112-2 in existing designs?

A: Yes. The 5745112-2 maintains full electrical and mechanical compatibility with the 745112-2. All critical parameters including connector type, position count, shell size, mounting configuration, current rating, voltage rating, and operating temperature range are identical. The connector will function identically in the same circuit and PCB layout.

Q: What is the difference between the contact materials in these two parts?

A: The 745112-2 uses copper alloy contacts, while the 5745112-2 uses phosphor bronze contacts. Both materials are suitable for the 6A current rating and 125V voltage rating specified for this connector. Both are gold-plated for signal integrity. The material difference does not affect electrical performance in standard applications.

Q: Why is the 745112-2 marked as obsolete?

A: The 745112-2 is classified as obsolete by TE Connectivity. The 5745112-2 is the active equivalent part. For new designs and ongoing production, the 5745112-2 should be specified to ensure long-term availability and supply chain continuity.

Q: Does the 5745112-2 meet RoHS requirements?

A: Yes. The 5745112-2 is RoHS compliant. The original 745112-2 is RoHS non-compliant. If your application or market requires RoHS compliance, the 5745112-2 is the appropriate selection.

Q: Are there any packaging differences between these parts?

A: The 5745112-2 is supplied in tray packaging. The original packaging specification for the 745112-2 is not provided in the technical data. Verify that tray packaging is compatible with your assembly and procurement processes.

Q: Can I use the 5745112-2 in applications requiring REACH compliance?

A: The 5745112-2 is REACH unaffected. The 745112-2 has vendor-undefined REACH status. For applications subject to REACH regulations, the 5745112-2 provides defined compliance status.

Q: Are the electrical ratings identical between these two connectors?

A: Yes. Both connectors have identical current rating (6A), voltage rating (125V), operating temperature range (-55°C to 105°C), and flammability rating (UL94 V-0). They are electrically equivalent.

Q: Will the 5745112-2 fit the same PCB footprint as the 745112-2?

A: Yes. Both connectors have identical mounting type (through-hole, right angle), backset spacing (0.545" / 13.84mm), and flange configuration (mating side with standard 4-40 screws). The mechanical footprint is identical.
