TE Connectivity AMP Connectors 745439-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 745439-4 is a 15 Position D-Sub Receptacle connector with female sockets, designed for right-angle solder termination applications. This connector belongs to the AMPLIMITE HDP-20 series and features a 2-row (DA, A) shell size configuration with mating-side flanges and standard screws.

The 745439-4 is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, repair, and continued operation where original components are no longer readily available or where design updates require compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 745439-4 is based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Connector Style: D-Sub
• Number of Positions: 15
• Number of Rows: 2
• Shell Size, Connector Layout: 2 (DA, A)
• Termination: Solder
• Operating Temperature Range: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0

Differing Parameters: The substitute part 183-015-113R171 (NorComp Inc.) differs in connector type (Plug, Male Pins versus Receptacle, Female Sockets), which indicates it functions as a mating connector rather than a direct replacement. This part is suitable for applications requiring a complementary D-Sub connector interface with the same 15-position, 2-row configuration and solder termination.

The 183-015-113R171 is classified as an active product with ROHS3 compliance, providing an alternative for new designs or legacy system updates where both receptacle and plug connectors are required.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Receptacle Function): The 745439-4 is an obsolete product. Direct replacement receptacle connectors with identical specifications (15-position, 2-row D-Sub, female sockets, right-angle solder termination) should be sourced from active product lines within TE Connectivity's current AMPLIMITE HDP-20 series or equivalent D-Sub receptacle offerings from other manufacturers.

For Complementary Mating Connector (Plug Function): The NorComp Inc. 183-015-113R171 serves as a mating plug connector for applications requiring both receptacle and plug interfaces. This part is active and ROHS3 compliant, making it suitable for new designs or system upgrades. The 183-015-113R171 maintains compatibility with the 15-position, 2-row D-Sub configuration and solder termination method.

Compliance Considerations: The 745439-4 is RoHS non-compliant. Systems requiring RoHS compliance should transition to compliant alternatives such as the 183-015-113R171 (ROHS3 compliant) or other current-generation D-Sub connectors from active product lines.

Current Rating Differential: The 745439-4 supports 6A current rating, while the 183-015-113R171 supports 5A. Applications requiring the full 6A capacity must verify that substitute parts meet this electrical requirement.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-015-113R171 directly replace the TE Connectivity 745439-4?

A: No. The 183-015-113R171 is a plug connector (male pins) while the 745439-4 is a receptacle connector (female sockets). These are complementary connectors designed to mate with each other, not direct replacements. For direct replacement of the receptacle function, an equivalent 15-position D-Sub receptacle connector must be sourced.

Q: What are the key compatibility criteria for D-Sub connector substitution?

A: Substitution compatibility is determined by: connector style (D-Sub), number of positions (15), number of rows (2), shell size and layout (2 DA, A), mounting type (right angle), and termination method (solder). Operating temperature range (-55°C to 105°C) and flammability rating (UL94 V-0) must also be maintained.

Q: Why is the 745439-4 listed as obsolete?

A: The 745439-4 is classified as an obsolete product by TE Connectivity, indicating it is no longer in active production. Obsolete status necessitates identification of equivalent alternatives for ongoing system support and maintenance.

Q: What is the significance of the current rating difference between these connectors?

A: The 745439-4 is rated for 6A while the 183-015-113R171 is rated for 5A. Applications operating at currents between 5A and 6A must account for this difference when selecting substitute components.

Q: Are there RoHS compliance implications for substitution?

A: Yes. The 745439-4 is RoHS non-compliant while the 183-015-113R171 is ROHS3 compliant. Systems subject to RoHS regulations should transition to compliant alternatives. Legacy systems not subject to RoHS requirements may continue using non-compliant components.

Q: What packaging differences exist between these parts?

A: The 745439-4 packaging is not specified in available documentation. The 183-015-113R171 is supplied in tray packaging. Packaging format should be confirmed with suppliers based on specific application requirements.

Q: How do the shell material finishes compare?

A: The 745439-4 features steel with tin plating, while the 183-015-113R171 features steel with nickel plating. Both maintain gold contact finish. Material finish selection may impact corrosion resistance in specific environmental conditions.
