Part Overview
The TE Connectivity AMP Connectors 745440-1 is a 25 Position D-Sub Receptacle connector with female sockets, right-angle through-hole mounting, and solder termination. This connector is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. The AMPLIMITE HDP-20 series connector features a DB/B shell size (Size 3) with tin-plated steel shell and gold-flashed phosphor bronze contacts rated for 6A at 125V operation across the temperature range of -55°C to 105°C.

Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 5745440-1
The 5745440-1 represents the direct active equivalent from the original manufacturer. This part maintains identical electrical specifications (6A at 125V), identical operating temperature range (-55°C to 105°C), and identical connector geometry. The primary distinction is product status (Active versus Obsolete) and RoHS compliance. The 5745440-1 is RoHS Compliant with REACH Unaffected status, making it suitable for applications subject to environmental regulations. Packaging is provided in Tray format with 1034 units in stock.
Secondary Recommendations: HARTING Cross-Manufacturer Alternatives
HARTING D-Sub 25-position receptors provide functional equivalence with the following considerations:
-
09643147232 and 09643147242: These parts exceed the original current rating (7.5A versus 6A) and extend the upper operating temperature to 125°C. Both feature Housing/Shell (4-40) flange configuration with Board Lock and Filter features. Backset spacing differs at 0.401" (10.20mm) versus the original 0.454" (11.53mm), requiring PCB layout verification.
-
09663126603, 09663127603, 09663136603: These alternatives feature Mating Side Female Screwlock (4-40) flange configuration with 6.5A current rating and 0.409" (10.40mm) backset spacing. Operating temperature extends to 125°C. Contact form is Stamped versus the original configuration.
-
09663526613 and 09663526617: These parts include Board Lock feature with Female Screwlock (4-40) flange. Packaging options include Tray (09663526613) and Bulk (09663526617). Both maintain 6.5A current rating and extended temperature range to 125°C.
All HARTING alternatives are ROHS3 Compliant with REACH Unaffected status. Backset spacing and flange feature differences require mechanical compatibility verification with existing PCB designs and mating connector specifications.
Frequently Asked Questions (FAQ)
Q: Can the 5745440-1 be used as a direct replacement for the 745440-1?
A: Yes. The 5745440-1 maintains identical electrical specifications, connector geometry, and operating parameters. The primary differences are product status (Active versus Obsolete) and RoHS compliance. No design modifications are required for substitution.
Q: What is the significance of the backset spacing difference in HARTING alternatives?
A: Backset spacing defines the distance from the mounting flange to the mating face of the connector. The original 745440-1 specifies 0.454" (11.53mm), while HARTING alternatives specify 0.401" (10.20mm) or 0.409" (10.40mm). This difference affects PCB layout and clearance to mating connectors. Mechanical compatibility must be verified before substitution.
Q: Are HARTING parts electrically compatible with the original TE Connectivity connector?
A: HARTING alternatives meet or exceed the electrical specifications of the original part. Current ratings range from 6.5A to 7.5A (versus 6A original), and operating temperature ranges extend to 125°C (versus 105°C original). All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. Electrical compatibility is confirmed; mechanical compatibility requires verification.
Q: What is the difference between the flange features listed for different substitutes?
A: Flange features define the mounting interface. The original 745440-1 specifies Mating Side with Standard Screws. HARTING alternatives offer Housing/Shell (4-40) or Mating Side Female Screwlock (4-40) configurations. These differences affect the mounting method and screw specifications. Selection depends on the mating connector and PCB mounting requirements.
Q: Why do some HARTING parts list no voltage rating?
A: Voltage rating is not specified in the provided data for certain HARTING alternatives. This does not indicate inadequate voltage capability; rather, the specification is not documented in the available technical parameters. The original part specifies 125V; HARTING parts with documented voltage ratings specify 100V minimum, which is suitable for the original application.
Q: What is the significance of RoHS compliance for this connector?
A: The original 745440-1 is RoHS non-compliant. All active substitute parts (5745440-1 and HARTING alternatives) are RoHS Compliant or ROHS3 Compliant. RoHS compliance is required for applications subject to European Union environmental regulations and is increasingly required by OEMs regardless of geographic location. Substitution to RoHS-compliant parts is recommended for new designs and long-term supply chain sustainability.
Q: Can packaging format (Tray versus Bulk) affect connector performance?
A: Packaging format does not affect connector electrical or mechanical performance. Tray packaging (5745440-1, 09663526613) provides organized component presentation and is typically used for automated assembly processes. Bulk packaging (HARTING alternatives) is used for manual assembly or high-volume applications. Selection depends on assembly process requirements and inventory management practices.
Q: What inventory levels are available for each substitute part?
A: Current inventory levels are as follows: 5745440-1 (1034 units), 09643147232 (1052 units), 09643147242 (790 units), 09663126603 (1187 units), 09663127603 (1047 units), 09663136603 (1051 units), 09663526613 (1051 units), 09663526617 (854 units), 09663527613 (953 units). All parts are listed as New Original In Stock.
