TE Connectivity 745187-1 D-Sub Receptacle 25 Position Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745187-1 is a 25 position D-Sub receptacle connector with female sockets, designed for through-hole vertical solder termination. This connector is part of the AMPLIMITE HDP-20 series and is classified as an active product. The 745187-1 features a DB/B shell size (Size 3) with tin-plated steel housing and gold-flashed phosphor bronze contacts rated for 6A at 125V operation across a temperature range of -55°C to 105°C.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative compliance requirements must be met, or when design modifications require different mounting configurations or material specifications while maintaining electrical and mechanical compatibility within the D-Sub connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub receptacle connectors is determined by strict equivalence across the following critical parameters: connector style (D-Sub), connector type (receptacle with female sockets), number of positions (25), number of rows (2), shell size and layout (Size 3, DB/B), mounting type (through hole), termination method (solder), and material flammability rating (UL94 V-0).

The 745187-1 has been grouped into two substitution categories:

Direct Equivalent: Part 5745187-1 from TE Connectivity maintains identical electrical and mechanical specifications with the exception of dielectric material composition and RoHS compliance status. This part is functionally interchangeable for applications where the dielectric material change from thermoplastic to polyamide (PA) nylon glass-filled composition is acceptable.

Similar Substitutes: Parts from NorComp Inc. (171-025-213R001, 172-025-283L001, 172-025-283L011, 172-025-283L021, and 172-E25-213R001) maintain the core D-Sub 25-position receptacle configuration with female sockets, Size 3 shell, and solder termination. These parts differ in mounting type (panel mount with through hole capability), shell finish (nickel plated instead of tin plated), contact material (brass instead of phosphor bronze), current rating (5A instead of 6A), and dielectric material composition. These substitutes are applicable when panel mount capability is required or when RoHS3 compliance is mandated.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (5745187-1):

The TE Connectivity 5745187-1 is the primary direct equivalent to the 745187-1. Both parts maintain identical electrical ratings (6A at 125V), operating temperature range (-55°C to 105°C), and mechanical configuration (25-position D-Sub receptacle, Size 3, through-hole solder termination). The 5745187-1 achieves RoHS compliance status while the original 745187-1 does not. Selection of 5745187-1 is appropriate when RoHS compliance is required for new designs or when the original part becomes unavailable. The dielectric material change from thermoplastic to polyamide (PA) nylon glass-filled composition does not affect electrical or mechanical compatibility.

NorComp Substitute Selection (171-025-213R001, 172-025-283L001, 172-025-283L011, 172-025-283L021, 172-E25-213R001):

NorComp D-Sub receptacles provide substitution options when panel mount capability is required or when ROHS3 compliance is mandated. All NorComp substitutes maintain the 25-position D-Sub receptacle configuration with Size 3 shell and solder termination. These parts are rated for 5A current (compared to 6A for the 745187-1) and feature brass contacts instead of phosphor bronze. Operating temperature ranges extend to 125°C for the 172-series parts (172-025-283L001, 172-025-283L011, 172-025-283L021), providing enhanced thermal capability.

Selection among NorComp substitutes depends on specific mounting and flange requirements:

• 171-025-213R001: Panel mount with unthreaded housing flange, nickel-plated steel shell, stamped brass contacts, operating range -50°C to 100°C
• 172-025-283L001: Panel mount with unthreaded housing flange, nickel-plated steel shell, machined brass contacts, operating range -50°C to 125°C
• 172-025-283L011: Panel mount with board-side 4-40 threaded flange, nickel-plated steel shell, machined brass contacts, operating range -50°C to 125°C
• 172-025-283L021: Panel mount with board-side 4-40 threaded flange, nickel-plated steel shell, machined brass contacts, operating range -50°C to 125°C
• 172-E25-213R001: Panel mount with unthreaded housing flange, nickel-plated steel shell, machined brass contacts, white color, operating range -50°C to 100°C

All NorComp substitutes carry ROHS3 compliance and are classified as active products.

Frequently Asked Questions (FAQ)

Q: Can the 5745187-1 be used as a direct replacement for the 745187-1 in existing designs?

A: Yes. The 5745187-1 maintains identical electrical ratings (6A, 125V), mechanical configuration (25-position D-Sub receptacle, Size 3, through-hole solder termination), and operating temperature range (-55°C to 105°C). The primary difference is RoHS compliance status and dielectric material composition. Both parts are manufactured by TE Connectivity and are classified as active products.

Q: What are the key differences between the 745187-1 and NorComp substitutes?

A: The primary differences are: (1) mounting type—NorComp parts support panel mount in addition to through-hole, while 745187-1 supports through-hole only; (2) current rating—NorComp parts are rated for 5A versus 6A for the 745187-1; (3) contact material—NorComp parts use brass contacts versus phosphor bronze for the 745187-1; (4) shell finish—NorComp parts feature nickel plating versus tin plating for the 745187-1; (5) compliance—all NorComp parts are ROHS3 compliant while the 745187-1 is not RoHS compliant.

Q: Are NorComp D-Sub receptacles electrically compatible with the 745187-1?

A: NorComp substitutes maintain electrical compatibility for the 25-position D-Sub receptacle interface. However, the reduced current rating (5A versus 6A) must be considered for applications requiring the full 6A capacity. All substitutes maintain the UL94 V-0 flammability rating and support solder termination.

Q: What is the difference between the 172-025-283L001, 172-025-283L011, and 172-025-283L021 parts?

A: These three NorComp parts are identical except for flange configuration. The 172-025-283L001 features an unthreaded housing/shell flange. The 172-025-283L011 and 172-025-283L021 both feature board-side 4-40 threaded flanges for direct PCB mounting with fasteners. All three parts share identical electrical ratings (5A), operating temperature range (-50°C to 125°C), and material specifications.

Q: Can I use a NorComp substitute if my application requires 6A current rating?

A: No. NorComp substitutes are rated for 5A maximum current, while the 745187-1 is rated for 6A. Applications requiring 6A operation must use the 745187-1 or the direct equivalent 5745187-1.

Q: What packaging options are available for these D-Sub receptacles?

A: The 745187-1 is supplied in tube packaging. The 5745187-1 is also supplied in tube packaging. NorComp substitutes are supplied in tray packaging (171-025-213R001, 172-025-283L001, 172-025-283L011, 172-025-283L021, 172-E25-213R001), with the exception of 172-025-282-031 for which packaging is not specified.

Q: Are all substitute parts classified as active products?

A: Yes. The 745187-1, 5745187-1, and all listed NorComp substitutes (171-025-213R001, 172-025-283L001, 172-025-283L011, 172-025-283L021, 172-E25-213R001) are classified as active products with current manufacturing status.

Q: What is the operating temperature range difference between the 745187-1 and NorComp substitutes?

A: The 745187-1 operates from -55°C to 105°C. NorComp 171-series and 172-E25 parts operate from -50°C to 100°C. NorComp 172-series parts (172-025-283L001, 172-025-283L011, 172-025-283L021) operate from -50°C to 125°C, providing extended high-temperature capability.

Q: Why would I choose a NorComp substitute over the direct equivalent 5745187-1?

A: NorComp substitutes are selected when panel mount capability is required for the application. The 745187-1 and 5745187-1 support through-hole mounting only. NorComp parts provide both panel mount and through-hole options, making them suitable for designs requiring panel-mounted D-Sub connectors. Additionally, NorComp 172-series parts offer extended operating temperature to 125°C compared to 105°C for the TE Connectivity parts.
