Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCE17B25PC640 are qualified based on the following critical parameters that must remain constant across all alternatives:

Core Electrical and Mechanical Compatibility 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
• Color: Black

Allowable Variations in Substitute Parts: Substitute parts may differ in the following parameters while maintaining functional equivalence:

• Manufacturer and series designation
• Shell material finish (Steel Tin Plated vs. Steel Nickel Plated)
• Contact material (Phosphor Bronze vs. Brass)
• Contact finish thickness (15.0µin vs. Flash)
• Flange feature design (Housing/Shell M3, Housing/Shell Unthreaded, Housing/Shell 4-40, Mating Side Female Screwlock 4-40)
• Dielectric material composition (Thermoplastic Glass Filled vs. Polyamide PA9T Nylon 9T)
• Operating temperature range (-40°C ~ 85°C vs. -55°C ~ 105°C)
• RoHS compliance variant (RoHS Compliant vs. ROHS3 Compliant)
• Packaging format (Bulk vs. Tray)
• Specific features (Board Lock, Filter, Ground Strap, Grounding Indents combinations)

All five substitute parts meet the core compatibility requirements and are functionally equivalent for D-Sub 25 position plug applications.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are active production components with current availability and meet the core functional requirements for D-Sub 25 position plug connector applications. Selection among the alternatives should be based on the following criteria:

Compliance and Regulatory Status: All substitute parts are ROHS3 compliant, which represents an updated RoHS compliance standard. The primary part FCE17B25PC640 is RoHS compliant. Both compliance levels are acceptable for most applications; however, ROHS3 compliance provides alignment with current regulatory requirements.

Operating Temperature Range: The primary part operates from -40°C to 85°C. All five substitute parts extend the operating range to -55°C to 105°C, providing broader thermal capability. This extended range is beneficial for applications requiring operation in extreme temperature environments but is not required for applications within the primary part's specified range.

Material and Contact Specifications: The primary part uses Phosphor Bronze contacts with 15.0µin gold plating thickness. Substitute parts use Brass contacts with flash gold plating. Both material combinations are suitable for signal-level applications at 5A current rating. The flash plating on substitute parts is thinner but adequate for the specified current and contact pressure requirements.

Shell Finish: The primary part features tin plating on the steel shell. Substitute parts feature nickel plating. Both finishes provide corrosion resistance and are suitable for the specified operating environment.

Mechanical Features: Substitute parts offer variations in flange design (unthreaded, threaded 4-40, or mating side screwlock) and feature combinations (ground strap availability, board lock options). Selection should align with the specific mechanical mounting requirements of the application.

Packaging: The primary part is supplied in bulk packaging. All substitute parts are supplied in tray packaging, which may affect handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can I use any of the NorComp 183 series parts as a direct replacement for the Amphenol FCE17B25PC640?

A: Yes. All five NorComp substitute parts (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are functionally equivalent for D-Sub 25 position plug applications. They maintain identical electrical and mechanical compatibility in terms of pin count, shell size, mounting configuration, current rating, and solder termination. Differences in contact material, shell finish, and operating temperature range do not affect functional compatibility for standard signal applications.

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

A: The five NorComp parts differ in flange feature design and feature combinations. Part 183-025-113R161 has an unthreaded housing shell flange. Parts 183-025-113R171 and 183-025-113R531 have threaded 4-40 housing shell flanges. Parts 183-025-113R181 and 183-025-113R561 have mating side female screwlock 4-40 flanges. Additionally, parts 183-025-113R531 and 183-025-113R561 include board lock features, while parts 183-025-113R161, 183-025-113R171, and 183-025-113R181 include ground strap features. Selection depends on the specific mechanical mounting and grounding requirements of your application.

Q: Does the difference in contact material (Phosphor Bronze vs. Brass) affect performance?

A: For signal-level applications at the 5A current rating specified, both Phosphor Bronze and Brass contact materials are suitable. Both materials provide adequate electrical conductivity and mechanical durability. The choice between them is typically driven by cost, availability, and specific environmental requirements rather than functional performance in this application class.

Q: Why do the substitute parts have a wider operating temperature range (-55°C to 105°C vs. -40°C to 85°C)?

A: The extended temperature range of the substitute parts reflects the design and qualification of the NorComp 183 series connectors. This broader range does not affect compatibility with applications operating within the primary part's specified range. If your application requires operation below -40°C or above 85°C, the substitute parts provide additional thermal capability.

Q: Are there any compatibility issues with the different flange designs?

A: The flange design variations (unthreaded, threaded 4-40, or mating side screwlock) affect the mechanical mounting interface but not the electrical or signal integrity. Selection should be based on your PCB layout, panel mounting requirements, and connector retention needs. Ensure that your application's mechanical design accommodates the specific flange configuration of the selected substitute part.

Q: What is the significance of the packaging difference (bulk vs. tray)?

A: Packaging format affects handling, storage, and component management procedures but does not affect the connector's electrical or mechanical performance. Tray packaging provides better organization and protection during storage and handling compared to bulk packaging. Verify that your assembly process and component handling equipment are compatible with tray-packaged components.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part is RoHS compliant, and all five substitute parts are ROHS3 compliant. ROHS3 represents an updated compliance standard that includes additional restricted substances. Both compliance levels meet current regulatory requirements for most applications.

Q: Can I mix the primary part and substitute parts in the same assembly?

A: Yes. All parts are functionally equivalent for D-Sub 25 position plug applications and can be used interchangeably within the same assembly. However, it is recommended to standardize on a single part number for a given design to simplify procurement, inventory management, and field service procedures.
