TE Connectivity AMP Connectors 749374-1 D-Sub HD Receptacle 15 Position Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 749374-1 is a 15 Position D-Sub High Density Receptacle connector with female sockets, designed for through-hole solder termination applications. This connector features a steel nickel-plated shell with gold-plated phosphor bronze contacts, rated for 1.5A at 125V, and operates across a temperature range of -55°C to 105°C. The part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement requirements. Substitute parts are available from alternative manufacturers that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 749374-1 are identified based on strict alignment with the following critical parameters: connector type (D-Sub High Density Receptacle with female sockets), position count (15 positions), row configuration (3 rows), shell size and layout (1 DE/E High Density), termination method (solder), and material specifications (steel nickel-plated shell with gold-plated contacts). Substitute parts must maintain compatibility with through-hole mounting applications and operate within the specified electrical ratings and temperature ranges. The substitution logic prioritizes functional equivalence in connector geometry, contact configuration, and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Mercury United Electronics 638-015-630-042 provides direct functional substitution for the TE Connectivity 749374-1, maintaining identical connector geometry, position count, row configuration, shell size, and solder termination method. Both parts feature steel nickel-plated shells with gold-plated contacts and are designed for through-hole mounting applications.

The NorComp 180-015-213R011 offers an alternative substitute with the same core connector specifications and geometry. This part is currently in active product status and carries ROHS3 compliance certification, providing a path to RoHS-compliant designs. The NorComp part supports both panel mount and through-hole mounting configurations, offering additional mechanical flexibility. The current rating of 3A exceeds the original 1.5A specification, and the operating temperature range of -50°C to 100°C is slightly narrower than the original -55°C to 105°C range. The contact material differs (brass versus phosphor bronze), and the dielectric material is specified as PBT without glass fill notation.

Selection between substitute parts depends on compliance requirements, mounting configuration needs, and thermal operating envelope constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the Mercury United 638-015-630-042 be used as a direct replacement for the TE Connectivity 749374-1?

A: Yes. Both connectors share identical specifications for connector type, position count, row configuration, shell size and layout, mounting type, and termination method. Both feature steel nickel-plated shells with gold-plated contacts suitable for through-hole solder applications.

Q: What are the key differences between the NorComp 180-015-213R011 and the original TE Connectivity part?

A: The NorComp part maintains the same connector geometry and core specifications but differs in the following areas: it supports panel mount in addition to through-hole mounting; it carries active product status and ROHS3 compliance; the current rating is 3A versus 1.5A; the operating temperature range is -50°C to 100°C versus -55°C to 105°C; and the contact material is brass rather than phosphor bronze.

Q: Are there any mounting configuration differences between the substitute parts?

A: The TE Connectivity 749374-1 and Mercury United 638-015-630-042 are both specified for through-hole mounting. The NorComp 180-015-213R011 supports both panel mount and through-hole mounting configurations, providing additional mechanical flexibility for board-level integration.

Q: What compliance considerations apply to these substitute parts?

A: The original TE Connectivity 749374-1 is RoHS non-compliant. The NorComp 180-015-213R011 is ROHS3 compliant, making it suitable for applications requiring RoHS compliance. Compliance status for the Mercury United part is not specified in the provided data.

Q: How do the electrical ratings compare across these parts?

A: The TE Connectivity 749374-1 is rated for 1.5A at 125V. The NorComp 180-015-213R011 is rated for 3A, providing higher current capacity. Voltage and current ratings for the Mercury United part are not specified in the provided data.

Q: What is the significance of the contact material differences?

A: The TE Connectivity 749374-1 uses phosphor bronze contacts, while the NorComp 180-015-213R011 uses brass contacts. Both materials are suitable for D-Sub connector applications. Contact material for the Mercury United part is not specified in the provided data.

Q: Are the operating temperature ranges compatible with the original specification?

A: The TE Connectivity 749374-1 operates from -55°C to 105°C. The NorComp 180-015-213R011 operates from -50°C to 100°C, representing a slightly narrower range. Applications requiring operation below -50°C or above 100°C require evaluation against the NorComp specification. Operating temperature for the Mercury United part is not specified in the provided data.
