FCE17B25PC400 D-Sub Plug Connector: Equivalent & Substitute Parts

Part Overview

The FCE17B25PC400 is a 25-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This right-angle, through-hole solder connector features male pins in a 2-row configuration with shell size 3 (DB, B) layout. The connector is designed for signal applications with a 5A current rating and operates across the temperature range of -40°C to 85°C. The part maintains active product status and is RoHS compliant with MSL 1 (unlimited moisture sensitivity level). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across manufacturers, enabling component selection flexibility for procurement, inventory management, or design revision scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC400 are identified based on strict equivalence of core electrical and mechanical parameters. The substitution criteria include:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (25)
• Number of rows (2)
• Shell size and layout (3, DB, B)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Current rating (5A)
• Backset spacing (0.590" / 14.99mm)
• Contact type (Signal)
• Material flammability rating (UL94 V-0)
• Contact finish (Gold)
• Color (Black)

All three substitute parts—183-025-113R161, 183-025-113R171, and 183-025-113R531 from NorComp Inc.—satisfy these core parameters. Variations exist in shell material finish (nickel-plated versus tin-plated), contact material composition (brass versus phosphor bronze), flange feature design (unthreaded versus 4-40 threaded), and operating temperature range extensions. These variations do not preclude substitution when the application requirements align with the substitute part specifications.

Parameter Comparison

Engineering Selection Recommendations

FCE17B25PC400 (Amphenol ICC): Select this part when the original design specification requires tin-plated steel shell finish, phosphor bronze contact material, or the specific operating temperature range of -40°C to 85°C. The part maintains active product status with RoHS compliance and MSL 1 rating. Current inventory is 781 pieces.

183-025-113R161 (NorComp Inc.): This substitute features an unthreaded flange design, distinguishing it from the 4-40 threaded variants. The nickel-plated steel shell and brass contacts provide equivalent electrical performance within the extended operating temperature range of -55°C to 105°C. ROHS3 compliance and higher inventory (1605 pieces) support procurement flexibility. Select this part when panel mount applications do not require threaded flange attachment.

183-025-113R171 (NorComp Inc.): This substitute maintains the 4-40 threaded flange feature matching the original design. Nickel-plated steel shell and brass contacts operate across -55°C to 105°C. ROHS3 compliance applies. Inventory of 2139 pieces provides robust supply availability. Select this part when threaded flange mounting is required and extended temperature performance is acceptable.

183-025-113R531 (NorComp Inc.): This substitute combines the 4-40 threaded flange with board lock feature. Nickel-plated steel shell and brass contacts support the extended -55°C to 105°C operating range. ROHS3 compliance applies. Inventory of 1392 pieces supports procurement needs. Select this part when board lock retention and threaded flange mounting are design requirements.

All substitute parts maintain active product status, equivalent electrical ratings, and compliance certifications suitable for direct component substitution in applications where the specified parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-025-113R161 substitute for the Amphenol FCE17B25PC400 in all applications?

A: The 183-025-113R161 substitutes functionally in applications where the unthreaded flange design is compatible with the PCB or panel mounting scheme. The extended operating temperature range (-55°C to 105°C) and nickel-plated finish support broader environmental conditions. Verify that the unthreaded flange does not conflict with existing mounting hardware specifications.

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

A: The primary differences are flange design and retention features. The 183-025-113R161 features an unthreaded flange. The 183-025-113R171 and 183-025-113R531 both include 4-40 threaded flanges. The 183-025-113R531 adds a board lock feature for enhanced retention. All three maintain identical electrical specifications and operating temperature ranges.

Q: Does the contact finish thickness difference affect substitution?

A: The FCE17B25PC400 specifies 15.0µin (0.38µm) gold contact finish thickness, while NorComp substitutes specify flash thickness. Both finishes provide gold contact plating for signal integrity. Flash thickness is thinner but sufficient for signal-level applications at 5A current rating. Verify application requirements for contact wear resistance if high-cycle mating is anticipated.

Q: Are the shell material differences significant?

A: The FCE17B25PC400 uses tin-plated steel; NorComp substitutes use nickel-plated steel. Both provide corrosion resistance and electromagnetic shielding. Nickel plating offers superior corrosion resistance in harsh environments. Tin plating is standard for general industrial applications. Select based on environmental exposure requirements.

Q: Can I use the 183-025-113R531 with board lock in place of the FCE17B25PC400?

A: Yes, the 183-025-113R531 substitutes electrically and mechanically. The board lock feature provides additional retention benefit. Ensure the PCB layout accommodates the board lock mechanism and that the 4-40 threaded flange aligns with mounting holes.

Q: What is the inventory status for each part?

A: FCE17B25PC400: 781 pieces. 183-025-113R161: 1605 pieces. 183-025-113R171: 2139 pieces. 183-025-113R531: 1392 pieces. All parts are new original stock.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FCE17B25PC400 is RoHS compliant. All three NorComp substitutes are ROHS3 compliant, meeting current regulatory requirements.
