FCE17B25SC65B D-Sub 25 Position Receptacle Equivalent & Substitute Parts
Part Overview
The FCE17B25SC65B is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This right-angle, through-hole solder termination connector features female sockets in a DB/B shell size (Size 3) configuration. The connector is actively produced and maintains a robust inventory of 1150 pieces in stock.
D-Sub receptacle connectors serve as mating interfaces in applications requiring standardized signal distribution across multiple circuits. Equivalent and substitute parts become necessary when addressing supply chain constraints, design revisions, or when alternative manufacturers offer compatible solutions with identical or enhanced electrical and mechanical specifications.

Engineering Selection Recommendations
All identified substitute parts maintain active product status and satisfy mandatory functional and electrical compatibility requirements. Selection among substitutes should be based on the following criteria:
NorComp 183 Series (183-025-213R541, 183-025-213R561, 183-025-213R571): These connectors provide direct functional equivalence with identical 25-position, 2-row, DB/B shell configuration and 0.590" backset spacing. All three variants are ROHS3 Compliant and operate across an extended temperature range of -55°C ~ 105°C. The primary distinction lies in flange feature configuration: 183-025-213R541 and 183-025-213R561 feature mating-side female screwlock (4-40), while 183-025-213R571 features housing/shell (4-40) mounting. Contact material is brass rather than phosphor bronze. Inventory availability ranges from 864 to 2006 pieces.
TE Connectivity AMPLIMITE HDP-20 Series (5205858-1): This connector delivers 6A current rating with phosphor bronze contacts and mounting brackets. The backset spacing of 0.545" (13.84mm) represents a minor deviation from the 0.590" specification. Yellow chromate plated zinc shell finish differs from tin plating. Voltage rating of 125V is specified. Inventory: 1300 pieces.
TE Connectivity AMPLIMITE HDP-20 Series (5745114-2): Tin-plated steel shell with phosphor bronze contacts, 6A current rating, and 0.545" backset spacing. Mounting brackets included. Voltage rating: 125V. Inventory: 1392 pieces.
TE Connectivity AMPLIMITE HD-20 Series (5745536-2, 5745992-3, 5747838-3, 5747838-4, 5747838-6): These five variants represent the most extensive inventory availability (1011 to 5499 pieces) and maintain tin-plated steel shells with phosphor bronze contacts. All feature 6A current rating and 125V voltage rating. Backset spacing is specified as 0.590" (14.99mm) for all except 5745536-2 (not specified). Flange features vary: 5745536-2 and 5745992-3 feature mating-side female screwlock (4-40) and housing/shell (4-40) respectively; 5747838-3, 5747838-4, and 5747838-6 feature housing/shell (4-40) and mating-side female screwlock (4-40) configurations. Board lock and ground strap features are present in 5747838 variants.
Compliance and Regulatory Status: All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. RoHS compliance is confirmed across all variants. TE Connectivity parts carry REACH Unaffected or Vendor Undefined status; NorComp parts carry REACH Unaffected status.
Frequently Asked Questions (FAQ)
Q: Can the NorComp 183-025-213R571 directly replace the FCE17B25SC65B in existing designs?
A: The 183-025-213R571 satisfies all mandatory functional parameters: 25 positions, 2 rows, DB/B shell size, through-hole right-angle mounting, solder termination, and 0.590" backset spacing. Operating temperature range extends to -55°C ~ 105°C, encompassing the original -40°C ~ 85°C specification. Contact material is brass rather than phosphor bronze, and shell finish is nickel plated rather than tin plated. These material differences do not preclude electrical or mechanical compatibility. Flange configuration (housing/shell 4-40) differs from the board-side M3 feature of the original part; verify mounting hole compatibility in your PCB design.
Q: What is the significance of the 0.545" backset spacing in TE Connectivity parts 5205858-1 and 5745114-2?
A: Backset spacing defines the distance from the connector mounting face to the rear of the connector body. The FCE17B25SC65B specifies 0.590" (14.99mm), while these TE Connectivity variants specify 0.545" (13.84mm). This 0.045" (1.15mm) difference affects PCB layout and enclosure clearance. If your design accommodates the original 0.590" spacing, these parts require verification that the reduced backset does not create interference with adjacent components or enclosure geometry.
Q: Are all substitute parts suitable for the same current and voltage applications?
A: The FCE17B25SC65B is rated for 5A with no specified voltage rating. TE Connectivity substitute parts (5205858-1, 5745114-2, 5745536-2, 5745992-3, 5747838-3, 5747838-4, 5747838-6) are rated for 6A at 125V, providing higher current capacity and defined voltage specification. NorComp parts (183-025-213R541, 183-025-213R561, 183-025-213R571) maintain 5A rating with no specified voltage. For applications requiring 5A operation, all substitutes are acceptable. For applications exceeding 5A, TE Connectivity variants with 6A rating are appropriate.
Q: What packaging format differences exist among the substitute parts?
A: The FCE17B25SC65B is supplied in standard packaging (not specified). NorComp parts are supplied in Tray packaging. TE Connectivity parts are supplied in either Bulk or Tube packaging. Packaging format affects handling, storage, and component presentation but does not alter electrical or mechanical compatibility. Verify packaging requirements for your procurement and assembly processes.
Q: How do contact material differences (phosphor bronze vs. brass) affect connector performance?
A: The FCE17B25SC65B uses phosphor bronze contacts; NorComp substitutes use brass contacts. Both materials provide adequate electrical conductivity and mechanical durability for signal-level D-Sub applications. Phosphor bronze offers superior spring characteristics and fatigue resistance; brass provides cost efficiency. For standard signal distribution applications within the specified current and temperature ranges, both materials deliver equivalent performance. Material selection does not preclude substitution.
Q: Which substitute part offers the highest inventory availability?
A: TE Connectivity part 5745536-2 (AMPLIMITE HD-20 series) maintains the highest inventory with 5499 pieces in stock. This part features tin-plated steel shell, phosphor bronze contacts, 6A current rating, 125V voltage rating, and mating-side female screwlock (4-40) flange configuration. Backset spacing is not specified for this variant.
Q: Are all substitute parts RoHS compliant?
A: All identified substitute parts are RoHS compliant or ROHS3 compliant. NorComp parts carry ROHS3 Compliant status. TE Connectivity parts carry RoHS Compliant status. Both compliance levels satisfy current regulatory requirements for electronic component procurement.
