TE Connectivity 749814-1 D-Sub 9-Position Receptacle Connector

Part Overview

The TE Connectivity 749814-1 is a 9-position D-Sub receptacle connector with female sockets, designed for IDC (Insulation Displacement Contact) and discrete wire termination. This connector is part of the AMPLIMITE HDE-20 series and features a shielded steel shell with tin plating and gold-flashed contacts. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

The TE Connectivity 749814-7 qualifies as a direct substitute for the 749814-1 based on identical electrical and mechanical parameters. Both connectors share the same core specifications: 9-position D-Sub receptacle configuration, shell size 1 (DE, E), free-hanging in-line mounting, IDC and discrete wire termination capability, steel tin-plated shell construction, gold-flashed contacts, 250V voltage rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability rating.

The substitution is valid across all functional and physical dimensions. The primary distinction between these parts is product status and compliance certification. The 749814-1 is obsolete and RoHS non-compliant, while the 749814-7 is active and RoHS compliant. Both parts maintain identical contact material (phosphor bronze), wire gauge compatibility (22-26 AWG), and connector geometry.

Engineering Selection Recommendations

The TE Connectivity 749814-7 is the appropriate substitute for the obsolete 749814-1 connector. Both parts deliver identical electrical performance and mechanical compatibility within the AMPLIMITE HDE-20 series. The 749814-7 offers the additional advantage of active product status and RoHS compliance, making it suitable for new designs and systems requiring regulatory adherence.

For applications where RoHS compliance is mandatory, the 749814-7 is the required selection. For legacy system maintenance or repair where the original 749814-1 is specified, the 749814-7 provides full functional equivalence with enhanced compliance certification. Both connectors support identical wire gauges (22-26 AWG), termination methods (IDC and discrete wire), and environmental operating conditions (-55°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can the 749814-7 be used as a direct replacement for the 749814-1 in existing assemblies?

A: Yes. The 749814-7 is electrically and mechanically identical to the 749814-1. Both connectors feature the same 9-position D-Sub receptacle configuration, shell size 1 (DE, E), mounting type, termination capabilities, and contact specifications. Physical fit and electrical performance are equivalent.

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

A: The 749814-1 is obsolete and RoHS non-compliant, while the 749814-7 is an active product with RoHS compliance. All functional and electrical parameters remain identical.

Q: Are there packaging differences between the 749814-1 and 749814-7?

A: The 749814-1 packaging specification is not provided in the technical data. The 749814-7 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both connectors support the same wire gauge range?

A: Yes. Both the 749814-1 and 749814-7 support 22-26 AWG wire gauges for both IDC and discrete wire termination methods.

Q: What is the voltage rating for these connectors?

A: Both connectors are rated for 250V operation.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both connectors operate across the temperature range of -55°C to 105°C and carry a UL94 V-0 flammability rating.

Q: Can these connectors be used in shielded applications?

A: Yes. Both the 749814-1 and 749814-7 feature shielded construction with steel tin-plated shells and gold-flashed contacts.
