FCE17B25PC44B D-Sub 25 Position Plug Connector Equivalent & Substitute Parts

Part Overview

The FCE17B25PC44B is a 25 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins, right-angle mounting, and solder termination for through-hole PCB applications. The connector is classified as an active product with full RoHS compliance and UL94 V-0 flammability rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC44B are identified based on strict equivalence across the following critical parameters:

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)
• Mounting configuration: Through hole, right angle
• Termination method: Solder
• Current rating: 5A
• Backset spacing: 0.590" (14.99mm)
• Contact type: Signal
• Flammability rating: UL94 V-0
• Color: Black

All substitute parts listed maintain these core parameters, ensuring mechanical and electrical interchangeability within the specified operating conditions. Variations in shell material finish, contact material composition, dielectric material formulation, and operating temperature range are noted in the parameter comparison table but do not preclude functional substitution when design specifications permit.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full compliance with applicable regulatory standards. The NorComp Inc. parts (183-025-113R161, 183-025-113R171, 183-025-113R531) are ROHS3 compliant and provide extended operating temperature ranges (-55°C ~ 105°C) compared to the primary part (-40°C ~ 85°C).

183-025-113R161: Features housing/shell flange without threaded mounting holes and includes ground strap functionality. Suitable for applications requiring panel mount capability without board-side threaded attachment.

183-025-113R171: Features housing/shell flange with 4-40 threaded mounting holes and includes ground strap functionality. Provides direct mechanical compatibility with board-side mounting requirements similar to the primary part.

183-025-113R531: Features housing/shell flange with 4-40 threaded mounting holes and board lock mechanism. Provides enhanced mechanical retention for high-vibration or high-shock environments.

All substitute parts employ nickel-plated steel shells and brass contact materials with flash gold plating, differing from the primary part's tin-plated steel shell and phosphor bronze contacts. These material variations do not compromise electrical performance within the specified 5A current rating and signal contact classification.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-025-113R series parts directly replace the Amphenol FCE17B25PC44B in existing designs?

A: Direct mechanical and electrical replacement is supported for applications where the operating temperature range of -40°C ~ 85°C is maintained. The NorComp parts support extended temperature operation to -55°C ~ 105°C, providing additional margin. Flange feature differences (board-side versus housing/shell mounting) must be evaluated against specific PCB layout requirements.

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

A: The primary differences are flange configuration and mounting features. The 183-025-113R161 uses an unthreaded housing/shell flange suitable for panel mount applications. The 183-025-113R171 and 183-025-113R531 both feature 4-40 threaded housing/shell flanges. The 183-025-113R531 includes a board lock feature for enhanced mechanical retention in high-vibration environments, while the 183-025-113R171 includes a ground strap.

Q: Are there compliance differences between the primary part and substitutes?

A: The primary part is RoHS Compliant. All substitute parts are ROHS3 Compliant, which represents a more recent and stringent compliance standard. Both compliance levels are acceptable for equivalent applications. The substitute parts include REACH Unaffected status, providing additional regulatory documentation.

Q: How do contact material differences affect performance?

A: The primary part uses phosphor bronze contacts; substitute parts use brass contacts. Both materials are standard for D-Sub signal connectors at the 5A current rating specified. Contact finish (gold plating) is identical across all parts. Material selection does not affect electrical performance within the specified operating parameters.

Q: What is the significance of the dielectric material differences?

A: The primary part uses thermoplastic glass-filled material; substitute parts use polyamide (PA9T) nylon 9T. Both materials meet UL94 V-0 flammability requirements and support the specified operating temperature ranges for their respective parts. Dielectric material selection does not affect connector functionality for signal contact applications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on specific mounting requirements. For board-side threaded mounting with ground strap, select 183-025-113R171. For board-side threaded mounting with board lock retention, select 183-025-113R531. For panel mount applications without board-side threading, select 183-025-113R161.
