FCE17B25PC40B D-Sub 25 Position Plug Connector Equivalent & Substitute Parts

Part Overview

The FCE17B25PC40B is a 25 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This D-shaped connector features male pins, right-angle mounting, and solder termination for through-hole PCB applications. The connector is classified as active product status with full RoHS compliance and UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC40B are identified based on strict alignment of core electrical and mechanical parameters. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 25
• Number of rows: 2
• Shell size, connector 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
• Contact finish: Gold
• Material flammability rating: UL94 V-0

All three substitute parts (183-025-113R161, 183-025-113R171, and 183-025-113R531) manufactured by NorComp Inc. meet these core parameters. Variations exist in shell material finish (nickel plated versus tin plated), dielectric material composition (polyamide PA9T versus thermoplastic glass filled), contact material (brass versus phosphor bronze), operating temperature range, and flange feature design. These variations do not preclude substitution when the application requirements fall within the specified operating parameters of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

All three NorComp substitute parts (183-025-113R161, 183-025-113R171, and 183-025-113R531) are active product status connectors with ROHS3 compliance, meeting or exceeding the regulatory requirements of the FCE17B25PC40B. The substitute parts provide extended operating temperature ranges (-55°C ~ 105°C) compared to the original part (-40°C ~ 85°C), enabling use in broader thermal environments.

183-025-113R161: This part features an unthreaded housing/shell flange and ground strap configuration. Selection is appropriate for applications requiring panel mount flexibility without threaded mounting holes.

183-025-113R171: This part includes a 4-40 threaded housing/shell flange with ground strap and grounding indents. Selection is appropriate for applications requiring board-side threaded mounting compatibility similar to the original FCE17B25PC40B design.

183-025-113R531: This part includes a 4-40 threaded housing/shell flange with board lock feature and grounding indents. Selection is appropriate for applications requiring positive mechanical retention and threaded mounting.

All substitute parts maintain the 5A current rating, 25 position configuration, and solder termination method. Shell material finish differs (nickel plated versus tin plated), and contact material composition differs (brass versus phosphor bronze), with no impact on electrical performance within the specified signal contact application. Dielectric material composition differs (polyamide PA9T versus thermoplastic glass filled), with both materials meeting UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-025-113R161 directly replace the Amphenol FCE17B25PC40B?

A: The 183-025-113R161 meets all core electrical and mechanical parameters including 25 position configuration, D-Sub shell size 3, solder termination, 5A current rating, and gold contact finish. The primary difference is the unthreaded housing/shell flange versus the board-side 4-40 threaded flange on the original part. Direct replacement is possible in applications where panel mount flexibility is acceptable or where the unthreaded flange does not conflict with existing mounting hardware.

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

A: All three parts share identical electrical specifications and core mechanical parameters. The primary differences are: (1) 183-025-113R161 features an unthreaded housing/shell flange; (2) 183-025-113R171 features a 4-40 threaded housing/shell flange with ground strap; (3) 183-025-113R531 features a 4-40 threaded housing/shell flange with board lock feature. Selection depends on the specific mounting and retention requirements of the application.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three NorComp substitute parts are ROHS3 compliant. The original FCE17B25PC40B is RoHS compliant. Both compliance levels meet current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in operating temperature range?

A: The FCE17B25PC40B operates from -40°C to 85°C. All three NorComp substitute parts operate from -55°C to 105°C. The extended temperature range of the substitute parts enables use in applications with more demanding thermal environments. Applications operating within the original -40°C to 85°C range are fully compatible with the substitute parts.

Q: Do the substitute parts have different contact materials?

A: Yes. The FCE17B25PC40B uses phosphor bronze contacts, while all three NorComp substitute parts use brass contacts. Both materials are suitable for signal contact applications and maintain the specified 5A current rating. Contact finish is gold on all parts, with the original part specifying 15.0µin thickness and the substitute parts specifying flash thickness.

Q: What is the difference in shell material finish?

A: The FCE17B25PC40B features a tin-plated steel shell. All three NorComp substitute parts feature nickel-plated steel shells. Both finishes provide corrosion resistance and are suitable for the specified operating environment. Nickel plating provides enhanced durability in high-humidity or corrosive environments.

Q: Are the substitute parts available in the same packaging?

A: The FCE17B25PC40B packaging is not specified in the provided data. All three NorComp substitute parts are supplied in tray packaging. Packaging format should be confirmed with the supplier if specific packaging requirements exist for the application.

Q: Can I use the 183-025-113R531 with board lock feature instead of the original part?

A: Yes. The 183-025-113R531 meets all core electrical and mechanical parameters of the FCE17B25PC40B. The board lock feature provides additional mechanical retention and is compatible with standard D-Sub 25 position receptacle connectors. The board lock feature does not interfere with normal connector mating and improves mechanical stability in vibration-prone applications.
