FCE17B25PC410 D-Sub Plug 25 Position Equivalent & Substitute Parts

Part Overview

The FCE17B25PC410 is a 25-position D-Sub plug connector manufactured by Amphenol ICC, designed for right-angle through-hole solder termination applications. This connector features male pins with a DB/B shell size (Size 3) and is rated for 5A continuous current operation across an operating temperature range of -40°C to 85°C. The part is RoHS compliant and currently active in production with 993 units in stock.

Equivalent and substitute parts are identified when design requirements permit flexibility in specific parameters such as shell finish, contact material, flange configuration, or operating temperature range, while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

NorComp 183 Series (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561)

The NorComp 183 series connectors are ROHS3 compliant alternatives with extended operating temperature ranges (-55°C to 105°C) compared to the FCE17B25PC410. These parts maintain the 25-position D-Sub configuration with identical backset spacing (0.590"). Key differences include nickel-plated steel shells and brass contact materials with flash gold finish. The 183-025-113R161 features an unthreaded housing flange, while 183-025-113R171 and 183-025-113R531 provide 4-40 threaded housing flanges. Parts 183-025-113R181 and 183-025-113R561 incorporate mating-side female screwlock flanges. All NorComp variants are suitable for applications requiring enhanced temperature performance and ROHS3 compliance.

TE Connectivity AMPLIMITE HDP-20 Series (205857-1, 5205857-1)

The TE Connectivity 205857-1 and 5205857-1 connectors provide 6A current rating with mating-side standard screw flanges. The 205857-1 is RoHS non-compliant with yellow chromate plated zinc shell finish, while 5205857-1 is ROHS3 compliant with identical shell finish. Both feature 0.545" backset spacing, which differs from the FCE17B25PC410. These parts are suitable for applications where higher current capacity and extended temperature range (-55°C to 105°C) are required, provided PCB layout accommodates the reduced backset spacing.

TE Connectivity AMPLIMITE HD-20 Series (5747022-2)

The 5747022-2 connector combines tin-plated steel shell finish (matching the FCE17B25PC410) with 6A current rating and ROHS3 compliance. It features mating-side female screwlock flanges and includes grounding indents and mounting brackets. Operating temperature range extends to -55°C to 105°C. The 0.545" backset spacing requires PCB layout verification. This part is suitable for applications requiring RoHS compliance, enhanced current capacity, and tin-plated shell compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the FCE17B25PC410 with a NorComp 183 series connector?

A: Yes, NorComp 183 series connectors (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are functionally equivalent for 25-position D-Sub solder applications. All maintain identical position count, shell size (DB/B Size 3), mounting orientation (right-angle through-hole), and backset spacing (0.590"). Differences include shell finish (nickel vs. tin plated), contact material (brass vs. phosphor bronze), and extended operating temperature range (-55°C to 105°C vs. -40°C to 85°C). Select the appropriate flange configuration based on your PCB design requirements.

Q: What is the difference between the NorComp parts with different flange features?

A: The NorComp 183 series offers three flange configurations: 183-025-113R161 features an unthreaded housing shell flange; 183-025-113R171 and 183-025-113R531 provide 4-40 threaded housing shell flanges; 183-025-113R181 and 183-025-113R561 incorporate mating-side female screwlock flanges. Select based on your mechanical mounting requirements and mating connector specifications.

Q: Why do TE Connectivity parts have different backset spacing?

A: TE Connectivity AMPLIMITE series connectors (205857-1, 5205857-1, 5747022-2) feature 0.545" backset spacing compared to 0.590" for the FCE17B25PC410 and NorComp parts. This spacing difference affects PCB layout and contact alignment. Verify your PCB design accommodates this variation before substitution.

Q: Are all substitute parts RoHS compliant?

A: Most substitutes are ROHS3 compliant. The exception is TE Connectivity 205857-1, which is RoHS non-compliant. For applications requiring RoHS compliance, select from NorComp 183 series parts, TE Connectivity 5205857-1, or TE Connectivity 5747022-2.

Q: What is the current rating difference between the main part and substitutes?

A: The FCE17B25PC410 is rated for 5A continuous current. TE Connectivity AMPLIMITE series substitutes (205857-1, 5205857-1, 5747022-2) provide 6A rating, offering higher current capacity. NorComp 183 series parts maintain 5A rating. Select based on your application's current requirements.

Q: Can I use a substitute with a higher operating temperature range?

A: Yes, provided your application operates within the substitute's temperature range. All NorComp and TE Connectivity substitutes support -55°C to 105°C operation, which encompasses the FCE17B25PC410 range of -40°C to 85°C. This provides additional thermal margin for demanding environments.

Q: What contact material differences should I consider?

A: The FCE17B25PC410 uses phosphor bronze contacts, while all substitutes use brass contacts. Both materials support gold plating and provide reliable signal transmission. Brass contacts in substitutes are flash gold plated, compared to 15.0µin thickness on the main part. For most applications, this difference is not significant.
