Engineering Selection Recommendations

Primary Equivalent Parts (NorComp 183 Series):

The NorComp Inc. 183 series connectors (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are direct functional equivalents to the FCE17B25PC4DB. All NorComp parts maintain ROHS3 compliance, which exceeds the RoHS Compliant status of the primary part. These connectors feature expanded operating temperature ranges (-55°C ~ 105°C) compared to the FCE17B25PC4DB (-40°C ~ 85°C), providing enhanced thermal performance for demanding applications. The NorComp parts utilize brass contact material and polyamide dielectric construction, which are functionally equivalent to the phosphor bronze and thermoplastic specifications of the primary part.

Differentiation among NorComp substitutes is based on flange feature configuration:

183-025-113R161: Housing/Shell flange (Unthreaded)
183-025-113R171: Housing/Shell flange (4-40 threaded)
183-025-113R181: Mating Side flange with Female Screwlock (4-40)
183-025-113R531: Housing/Shell flange (4-40 threaded) with Board Lock feature
183-025-113R561: Mating Side flange with Female Screwlock (4-40) and Board Lock feature

Secondary Equivalent Parts (TE Connectivity AMPLIMITE Series):

The TE Connectivity parts 205857-1, 5205857-1, and 5747022-2 are functionally equivalent with the following considerations:

205857-1: RoHS non-compliant status restricts use in regulated applications requiring RoHS certification. Current rating of 6A exceeds the 5A specification of the primary part. Backset spacing of 0.545" (13.84mm) differs from the 0.590" (14.99mm) standard, requiring board layout verification.
5205857-1: ROHS3 compliant alternative to 205857-1 with identical electrical and mechanical specifications. Recommended for applications requiring RoHS compliance. Backset spacing of 0.545" (13.84mm) requires board layout verification.
5747022-2: ROHS3 compliant with 6A current rating and 0.545" (13.84mm) backset spacing. Features tin-plated steel shell matching the primary part's finish specification. Backset spacing difference requires board layout verification.

Compliance Considerations:

For applications requiring RoHS compliance, select from NorComp 183 series (ROHS3 Compliant) or TE Connectivity 5205857-1 and 5747022-2 (ROHS3 Compliant). The TE Connectivity 205857-1 is not suitable for RoHS-regulated applications.

Backset Spacing Verification:

The NorComp 183 series maintains 0.590" (14.99mm) backset spacing identical to the FCE17B25PC4DB. The TE Connectivity AMPLIMITE series (205857-1, 5205857-1, 5747022-2) specifies 0.545" (13.84mm) backset spacing. Board layout and PCB hole positioning must be verified before substitution with TE Connectivity parts.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-025-113R161 directly replace the FCE17B25PC4DB without board modifications?

A: The 183-025-113R161 maintains identical backset spacing (0.590" / 14.99mm), connector layout (25 position, 2 row, DB-3 shell), and solder termination. The primary difference is the flange feature configuration (Housing/Shell unthreaded versus Board Side 4-40 threaded). Board-side mounting compatibility depends on the specific flange mounting holes in your PCB design. Verify flange hole patterns before substitution.

Q: What is the significance of the backset spacing difference between NorComp and TE Connectivity parts?

A: Backset spacing defines the distance from the connector mounting face to the solder contact plane. The NorComp 183 series specifies 0.590" (14.99mm), matching the FCE17B25PC4DB. The TE Connectivity AMPLIMITE series specifies 0.545" (13.84mm). This 0.045" (1.15mm) difference affects PCB hole positioning and connector seating depth. Substitution with TE Connectivity parts requires PCB layout verification to ensure proper connector alignment and solder joint formation.

Q: Are all substitute parts rated for the same current and voltage as the FCE17B25PC4DB?

A: The FCE17B25PC4DB is rated for 5A current with no specified voltage rating. NorComp 183 series parts maintain 5A current rating. TE Connectivity AMPLIMITE series parts (205857-1, 5205857-1, 5747022-2) are rated for 6A current, exceeding the primary part specification. TE Connectivity parts specify 125V voltage rating, while the FCE17B25PC4DB does not specify a voltage rating. The higher current and voltage ratings of TE Connectivity parts provide design margin for applications requiring enhanced electrical performance.

Q: What is the difference between the various NorComp flange feature options?

A: Flange features determine the mechanical mounting interface:

Housing/Shell (Unthreaded): Flange mounted to connector shell without threaded fasteners
Housing/Shell (4-40 Threaded): Flange with 4-40 threaded holes for screw fastening
Mating Side with Female Screwlock (4-40): Screwlock feature on the mating connector face with 4-40 threaded holes
Board Lock Feature: Additional mechanical locking mechanism for enhanced retention

Select the flange configuration matching your PCB mounting hole pattern and mechanical retention requirements.

Q: Why do some substitute parts have expanded operating temperature ranges?

A: The NorComp 183 series and TE Connectivity AMPLIMITE series specify -55°C ~ 105°C operating temperature, compared to the FCE17B25PC4DB specification of -40°C ~ 85°C. The expanded range reflects the dielectric material properties (polyamide versus thermoplastic) and manufacturing tolerances of each manufacturer. For applications operating within the FCE17B25PC4DB temperature range (-40°C ~ 85°C), all substitute parts are functionally equivalent. For applications requiring extended temperature performance, substitute parts provide additional thermal margin.

Q: Is the contact material difference between Phosphor Bronze and Brass significant?

A: The FCE17B25PC4DB uses Phosphor Bronze contacts, while all substitute parts use Brass contacts. Both materials provide gold plating for corrosion resistance and electrical conductivity. Brass contacts are widely used in D-Sub connectors and provide equivalent signal integrity and reliability for the 5A current rating. The contact finish (gold plating) is the primary factor determining electrical performance, not the base material composition.

Q: Which substitute part should I select for new designs?

A: For new designs requiring RoHS compliance and matching the FCE17B25PC4DB backset spacing, select from the NorComp 183 series (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, or 183-025-113R561). Choose the specific part number based on your required flange feature configuration. For applications where backset spacing can be accommodated and higher current rating is beneficial, TE Connectivity 5205857-1 or 5747022-2 are suitable alternatives with ROHS3 compliance.

Q: Can I use the TE Connectivity 205857-1 in a new design?

A: The 205857-1 is RoHS non-compliant and not recommended for new designs subject to RoHS regulations. Use the ROHS3 compliant alternative 5205857-1 instead. If the 205857-1 is already in production inventory, verify that your application and end-market do not require RoHS compliance before continuing use.

Q: What packaging formats are available for these substitute parts?

A: The FCE17B25PC4DB is supplied in standard packaging. NorComp 183 series parts are supplied in Tray packaging. TE Connectivity AMPLIMITE series parts (205857-1, 5205857-1, 5747022-2) are supplied in Bulk packaging. Verify packaging compatibility with your procurement and assembly processes before substitution.
