TE Connectivity 5745186-2 D-Sub Plug 25 Position Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5745186-2 is a 25 position D-Sub plug connector with male pins, designed for through-hole solder termination applications. This connector is part of the AMPLIMITE HDP-20 series and maintains active product status with 986 units in current inventory. The connector features a vertical orientation with a tin-plated steel shell and gold-flashed brass contacts, rated for 6A at 125V across an operating temperature range of -55°C to 105°C.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable, when alternative mounting configurations are required, or when design flexibility permits component variation within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5745186-2 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Position count: 25 positions
• Row configuration: 2 rows
• Shell size and layout: 3 (DB, B)
• Termination method: Solder
• Contact type: Signal
• Flammability rating: UL94 V-0

Identified Substitute Parts:

The NorComp Inc. 172-025-183L011 and 172-025-183L021 connectors satisfy the core compatibility parameters listed above. Both parts are 25 position D-Sub plug connectors with male pins, solder termination, and UL94 V-0 flammability rating. The primary distinction between these substitutes and the main part involves mounting configuration (panel mount with through-hole capability versus vertical through-hole only) and shell material finish (nickel-plated steel versus tin-plated steel).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 5745186-2 remains the primary selection for applications requiring vertical through-hole mounting with a 6A current rating and -55°C to 105°C operating temperature specification. This part maintains active product status with robust inventory availability and RoHS compliance certification.

Substitute Part Selection Criteria:

The NorComp 172-025-183L011 and NorComp 172-025-183L021 connectors are suitable substitutes when the following conditions are met:

1. Mounting Configuration Compatibility: Applications that accommodate panel mount with through-hole capability can utilize the NorComp substitutes. The panel mount feature provides additional mechanical stability compared to vertical through-hole only mounting.

2. Current Rating Tolerance: Applications with maximum current requirements of 5A or less can accept the NorComp substitutes, which are rated at 5A compared to the 6A rating of the primary part.

3. Operating Temperature Range: The NorComp substitutes support an extended upper temperature limit of 125°C compared to 105°C for the primary part, and a slightly higher lower temperature limit of -50°C compared to -55°C. Applications within the -50°C to 105°C range are fully compatible with all three parts.

4. Regulatory Compliance: All three parts maintain UL94 V-0 flammability rating, RoHS compliance (primary part: RoHS Compliant; substitutes: ROHS3 Compliant), and REACH Unaffected status. The ROHS3 compliance of the NorComp substitutes represents an updated regulatory standard.

5. Shell Material Finish: The NorComp substitutes feature nickel-plated steel shells compared to the tin-plated steel shell of the primary part. Both finishes provide corrosion resistance suitable for standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 172-025-183L011 or 172-025-183L021 be used as direct replacements for the TE Connectivity 5745186-2?

A: The NorComp connectors are functionally compatible substitutes for applications that do not require the full 6A current rating of the primary part and can accommodate panel mount mounting capability. Both parts share identical position count (25), row configuration (2), shell size (3 DB/B), termination method (solder), and flammability rating (UL94 V-0). The primary differences are current rating (5A versus 6A), mounting type (panel mount with through-hole versus through-hole only), and shell finish (nickel-plated versus tin-plated).

Q: What is the difference between the two NorComp substitute parts?

A: The NorComp 172-025-183L011 and 172-025-183L021 are functionally identical 25 position D-Sub plug connectors. Both parts share the same electrical specifications, mechanical configuration, and regulatory compliance status. The part numbers differ due to internal NorComp product line designation, but no technical distinction exists between these two parts for substitution purposes.

Q: Are there any temperature range limitations when substituting the NorComp parts?

A: The NorComp substitutes support an operating temperature range of -50°C to 125°C, compared to -55°C to 105°C for the primary part. Applications operating within the -50°C to 105°C range are fully compatible with all three connectors. Applications requiring operation below -50°C or above 105°C must use the TE Connectivity 5745186-2 primary part.

Q: What is the current rating difference, and does it affect substitution?

A: The TE Connectivity 5745186-2 is rated for 6A, while the NorComp substitutes are rated for 5A. Substitution is appropriate only for applications with maximum current requirements of 5A or less. Applications requiring the full 6A capacity must use the primary part.

Q: Do the different shell finishes (tin-plated versus nickel-plated) affect electrical performance?

A: Both tin-plated and nickel-plated steel shells provide equivalent electrical performance and corrosion resistance for standard industrial applications. The shell finish does not affect signal integrity, impedance, or contact resistance. Selection between finishes is based on environmental exposure and specific application requirements.

Q: Are all three connectors RoHS compliant?

A: Yes. The TE Connectivity 5745186-2 is RoHS Compliant, and the NorComp 172-025-183L011 and 172-025-183L021 are ROHS3 Compliant. ROHS3 represents an updated regulatory standard that supersedes the original RoHS designation. All three parts meet current RoHS requirements.

Q: What packaging differences exist between the primary part and substitutes?

A: The TE Connectivity 5745186-2 is supplied in tube packaging, while the NorComp substitutes are supplied in tray packaging. Packaging format does not affect connector performance or compatibility but may influence inventory management and handling procedures.

Q: Can the panel mount feature of the NorComp substitutes be ignored if vertical through-hole mounting is required?

A: Yes. The NorComp substitutes support both panel mount and through-hole mounting configurations. Applications requiring vertical through-hole mounting only can utilize the NorComp substitutes without activating the panel mount feature. The connector will function identically to the primary part in through-hole only applications.
