Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 745984-4 are classified into two categories based on functional and regulatory alignment:

Direct Equivalent (Active Status): The TE Connectivity 5745984-4 maintains identical connector specifications including 15-position D-Sub receptacle configuration, right-angle through-hole mounting, solder termination, and operating temperature range of -55°C to 105°C. This part differs in RoHS compliance status (RoHS Compliant versus Non-Compliant) and contact material composition (Phosphor Bronze versus Copper Alloy), while maintaining equivalent electrical performance at 6A current rating and 125V voltage rating.

Compatible Substitutes (Active Status): NorComp Inc. 183-series and Mercury United Electronics 626-series connectors provide functional substitution through matching core parameters: 15-position D-Sub receptacle configuration, right-angle mounting, solder termination, shell size 2 (DA, A), and UL94 V-0 flammability rating. These alternatives accommodate variations in current rating (5A for NorComp, 3A per contact for Mercury), shell finish (Nickel Plated versus Tin Plated), contact material (Brass versus Copper Alloy), and flange configuration (Housing/Shell 4-40, Unthreaded, or Mating Side Female Screwlock 4-40). All active substitutes comply with ROHS3 and maintain operating temperature ranges of -55°C to 85°C or -55°C to 105°C.

Substitution eligibility is determined by matching: connector style (D-Sub), connector type (Receptacle, Female Sockets), position count (15), row configuration (2), shell size (2 DA, A), mounting type (Through Hole, Right Angle), termination method (Solder), and material flammability rating (UL94 V-0).

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-series connectors directly replace the TE Connectivity 745984-4 in existing designs?

A: NorComp 183-series connectors are functionally compatible substitutes for the 745984-4 in applications where current requirements do not exceed 5A and operating temperatures remain within -55°C to 105°C. The 183-series maintains identical 15-position D-Sub receptacle configuration, right-angle through-hole solder termination, and shell size (2 DA, A). Flange configuration options vary across the 183-series lineup, allowing selection based on specific mounting requirements. All 183-series parts are ROHS3 Compliant and REACH Unaffected, addressing regulatory requirements for new designs.

Q: What is the primary difference between the 745984-4 and the 5745984-4?

A: The TE Connectivity 5745984-4 is the active equivalent of the obsolete 745984-4. Both parts maintain identical electrical specifications (6A current rating, 125V voltage rating), connector configuration (15-position D-Sub receptacle, right-angle through-hole solder termination), and operating temperature range (-55°C to 105°C). The 5745984-4 achieves RoHS Compliant status and REACH Unaffected certification, whereas the 745984-4 is RoHS Non-Compliant. Contact material differs (Phosphor Bronze versus Copper Alloy) but maintains equivalent electrical performance. The 5745984-4 is classified as Active and is the recommended replacement for new designs.

Q: Are there flange configuration options available among the substitute parts?

A: Yes. The NorComp 183-series provides multiple flange configuration options: Housing/Shell (Unthreaded) on 183-015-213R161, Housing/Shell (4-40) on 183-015-213R171 and 183-015-213R531, and Mating Side Female Screwlock (4-40) on 183-015-213R181, 183-015-213R481, 183-015-213R541, and 183-015-213R561. The TE Connectivity 5745984-4 and Mercury 626-015-662-012 both feature Housing/Shell (4-40) flange configuration. Selection of flange configuration depends on specific mounting and mating requirements in the application.

Q: What is the significance of the contact finish thickness difference between the 745984-4 and substitute parts?

A: The 745984-4 specifies contact finish thickness of 30.0µin (0.76µm), whereas NorComp 183-series parts specify Flash thickness. The TE Connectivity 5745984-4 maintains 30.0µin (0.76µm) thickness. Flash thickness is a thin gold plating applied to contact surfaces without specified minimum thickness. Both finishes provide gold contact surfaces for electrical conductivity and corrosion resistance. Flash thickness is acceptable for most applications and is standard across the NorComp 183-series lineup.

Q: Can the Mercury 626-015-662-012 be used in high-current applications?

A: No. The Mercury 626-015-662-012 is rated for 3A per contact, which is below the original 745984-4 specification of 6A. This part is suitable only for applications with current requirements not exceeding 3A per contact. For applications requiring 6A current capacity, the TE Connectivity 5745984-4 or NorComp 183-series parts rated at 5A or 6A are appropriate selections.

Q: What mounting type variations exist among the substitute parts?

A: The TE Connectivity 745984-4 and 5745984-4 specify Through Hole, Right Angle mounting. The Mercury 626-015-662-012 specifies Board Edge, Through Hole, Right Angle mounting, providing additional board edge mounting capability. The NorComp 183-series specifies Panel Mount, Through Hole, Right Angle mounting, accommodating panel-mounted applications. All parts maintain right-angle orientation for PCB-mounted configurations. Selection depends on specific mounting requirements in the application.

Q: Are all substitute parts RoHS Compliant?

A: The TE Connectivity 5745984-4 is RoHS Compliant. All NorComp 183-series parts are ROHS3 Compliant. The Mercury 626-015-662-012 is ROHS3 Compliant. The original 745984-4 is RoHS Non-Compliant. For new designs subject to RoHS requirements, the 5745984-4 or any NorComp 183-series part is appropriate. For legacy designs not subject to RoHS requirements, the 745984-4 remains available if stock permits.

Q: What is the difference between Board Lock and standard mounting features?

A: Board Lock is a mechanical feature present on NorComp 183-015-213R531, 183-015-213R541, 183-015-213R561, and 183-015-213R571. This feature provides additional mechanical retention on the PCB. The 745984-4, 5745984-4, and other substitute parts without Board Lock designation do not include this feature. Selection depends on whether additional mechanical retention is required in the application.

Q: Can the NorComp 183-series parts accommodate the full -55°C to 105°C operating temperature range?

A: Yes. All NorComp 183-series parts specify operating temperature range of -55°C to 105°C, matching the original 745984-4 and the 5745984-4. The Mercury 626-015-662-012 is limited to -55°C to 85°C, restricting use in applications requiring the full temperature range. For applications requiring -55°C to 105°C operation, the 5745984-4 or any NorComp 183-series part is appropriate.
