Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 745959-1 are grouped based on strict alignment of the following critical parameters:

Primary Substitution Criteria:

  • Connector type: D-Sub plug with male pins
  • Position count: 25 positions
  • Shell size: 3 (DB, B)
  • Mounting configuration: Through-hole capability
  • Termination method: Solder
  • Flange feature: Board-side (4-40)
  • Contact type: Signal
  • Flammability rating: UL94 V-0

Direct Equivalent (5745959-1): Identical to the main part across all electrical and mechanical parameters, with the exception of dielectric material composition and RoHS compliance status. This part maintains the same series designation, current rating, voltage rating, and operating temperature range.

Similar Substitutes (172-025-183L011, 172-025-183L021): These NorComp Inc. parts share the core D-Sub 25-position configuration, shell size, and solder termination. Both support through-hole and panel-mount configurations. Differences include shell finish (nickel-plated versus tin-plated), current rating (5A versus 6A), and dielectric material composition (PBT versus thermoplastic).

Engineering Selection Recommendations

5745959-1 (Direct Equivalent): This part is the primary substitute for 745959-1. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HDP-20 series and maintain identical electrical and mechanical specifications. The 5745959-1 offers ROHS3 compliance and REACH unaffected status, providing regulatory advantages for new designs. Current inventory of 2783 pieces supports production requirements.

172-025-183L011 and 172-025-183L021 (Similar Substitutes): These NorComp Inc. connectors are functionally compatible alternatives when the 6A current rating of the main part is not a limiting requirement. Both parts support the same 25-position D-Sub configuration with identical shell size and solder termination. The NorComp parts feature extended operating temperature range (-50°C to 125°C) and ROHS3 compliance. The primary trade-off is reduced current rating (5A versus 6A). These parts are suitable for applications where current demands do not exceed 5A and panel-mount capability is beneficial.

All substitute parts maintain UL94 V-0 flammability rating and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can 5745959-1 be used as a direct replacement for 745959-1?

A: Yes. The 5745959-1 maintains identical electrical and mechanical specifications including 25-position configuration, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. Both parts feature board-side flange mounting (4-40), solder termination, and UL94 V-0 flammability rating. The primary difference is dielectric material composition and regulatory compliance status.

Q: What are the limitations when substituting NorComp 172-025-183L011 or 172-025-183L021?

A: The NorComp parts have a reduced current rating of 5A compared to the 6A rating of the main part. Applications requiring current levels between 5A and 6A cannot use these substitutes. Additionally, the NorComp parts feature nickel-plated shell finish rather than tin-plated finish. Both NorComp parts support panel-mount configuration in addition to through-hole mounting.

Q: Are all substitute parts RoHS compliant?

A: The 5745959-1 is ROHS3 compliant. The NorComp parts (172-025-183L011 and 172-025-183L021) are also ROHS3 compliant. The original 745959-1 has RoHS status listed as not applicable.

Q: What is the difference in packaging between the main part and substitutes?

A: The main part 745959-1 is supplied in tube packaging. The direct equivalent 5745959-1 is also supplied in tube packaging. The NorComp substitutes (172-025-183L011 and 172-025-183L021) are supplied in tray packaging.

Q: Can the NorComp parts be used in panel-mount applications?

A: Yes. The NorComp parts (172-025-183L011 and 172-025-183L021) support both panel-mount and through-hole mounting configurations. The main part 745959-1 and direct equivalent 5745959-1 support through-hole mounting only.

Q: What is the operating temperature range difference?

A: The main part 745959-1 and direct equivalent 5745959-1 operate from -55°C to 105°C. The NorComp substitutes (172-025-183L011 and 172-025-183L021) operate from -50°C to 125°C, providing a wider upper temperature range but a slightly narrower lower temperature range.

Q: Are voltage ratings specified for all parts?

A: The main part 745959-1 and direct equivalent 5745959-1 have a specified voltage rating of 125V. The NorComp parts (172-025-183L011 and 172-025-183L021) do not have voltage ratings specified in the provided data.
