TE Connectivity 747947-5 D-Sub 25 Position Receptacle Connector

Part Overview

The TE Connectivity 747947-5 is a 25 position D-Sub receptacle connector featuring female sockets, designed for IDC (Insulation Displacement Contact) and discrete wire termination. This connector is part of the AMPLIMITE HDE-20 series and is classified as obsolete. The connector provides shielded signal transmission with a rated voltage of 250V and operates across a temperature range of -55°C to 105°C.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing maintenance, repair, and system support applications. Active production alternatives within the same series provide functional equivalence while offering improved availability and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-747947-7 provides direct functional equivalence to the 747947-5 across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

For New Designs and Active Production: The 1-747947-7 is the appropriate selection due to its Active product status and RoHS compliance certification. This part ensures ongoing availability from the manufacturer and compliance with current regulatory requirements for electronic components.

For Legacy System Maintenance: The 747947-5 remains functionally equivalent to the 1-747947-7 for repair and replacement applications in existing systems. However, the 1-747947-7 should be prioritized when available due to its active production status and improved compliance profile.

Compliance Considerations: The 1-747947-7 carries RoHS compliance certification, whereas the 747947-5 is RoHS non-compliant. Systems subject to RoHS regulatory requirements must utilize the 1-747947-7 for new installations or component replacements.

Both parts maintain identical electrical performance, mechanical compatibility, and environmental ratings. No functional degradation or performance loss occurs when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the 1-747947-7 directly replace the 747947-5 in existing applications?

A: Yes. The 1-747947-7 is electrically and mechanically equivalent to the 747947-5. All connector parameters, including pin count, shell size, termination method, voltage rating, and operating temperature range, are identical. Direct substitution is possible without modification to existing designs or installations.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and RoHS compliance. The 747947-5 is classified as obsolete and RoHS non-compliant, while the 1-747947-7 is an active product with RoHS compliance certification. All functional and mechanical specifications are identical.

Q: Are there packaging differences between the 747947-5 and 1-747947-7?

A: The 747947-5 is supplied in standard packaging, while the 1-747947-7 is supplied in bulk packaging. This difference does not affect connector performance or compatibility.

Q: Which part should be selected for new system designs?

A: The 1-747947-7 should be selected for new designs. This part is in active production, carries RoHS compliance certification, and ensures long-term availability and regulatory compliance.

Q: Are the termination methods identical between these parts?

A: Yes. Both parts support IDC (Insulation Displacement Contact) and discrete wire termination methods. Wire gauge compatibility is identical at 22-26 AWG for both parts.

Q: Do these connectors support the same voltage and temperature specifications?

A: Yes. Both parts are rated for 250V operation and function across the identical temperature range of -55°C to 105°C. Environmental performance characteristics are equivalent.

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

A: RoHS compliance indicates the 1-747947-7 meets regulatory restrictions on hazardous substances in electrical and electronic equipment. For applications subject to RoHS requirements, the 1-747947-7 is the required selection. The 747947-5, being RoHS non-compliant, may not be acceptable for new installations in regulated environments.
