Engineering Selection Recommendations

Primary Substitutes (Amphenol ICC FCE17 Series):

The FCE17B25PC40B, FCE17B25PC41B, FCE17B25PC44B, FCE17B25PC45B, FCE17B25PC48B, FCE17B25PC49B, FCE17B25PC4DB, and FCE17B25PC4EB connectors are direct functional equivalents to the FCC17B25PC40B. All FCE17 series parts maintain identical mechanical and electrical specifications across connector style, position count, shell size, mounting configuration, current rating, operating temperature range, and contact materials. The primary distinction is product status: all FCE17 variants are active production parts, whereas the FCC17B25PC40B is obsolete.

The FCE17 series parts are RoHS compliant, addressing regulatory requirements that the original FCC17B25PC40B does not meet. The dielectric material in FCE17 variants includes glass-filled thermoplastic formulations, which provide enhanced mechanical and thermal properties compared to standard thermoplastic.

Secondary Substitutes (HARTING 09653226800 and 09653227800):

The HARTING 09653226800 and 09653227800 connectors provide mechanical and electrical compatibility with the FCC17B25PC40B across all critical parameters: D-Sub connector style, 25 position plug configuration, Size 3 shell layout, right angle through-hole solder mounting, and board-side flange with 4-40 mounting holes. Both HARTING parts are active production items with RoHS3 compliance.

The HARTING connectors feature a higher current rating (6.5A versus 5A) and an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing additional performance margin. Contact material differs (Copper Alloy versus Phosphor Bronze) and backset spacing is reduced (0.409" versus 0.590"), which may affect board layout compatibility in applications with tight spacing constraints.

Selection Criteria:

For applications requiring regulatory compliance and continued component availability, the Amphenol ICC FCE17 series provides the most direct substitution path with identical form factor and electrical performance. For applications requiring extended temperature operation or higher current capacity, the HARTING alternatives offer enhanced specifications with the trade-off of different contact material and reduced backset spacing.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25PC40B directly replace the FCC17B25PC40B in existing designs?

A: Yes. The FCE17B25PC40B maintains identical mechanical and electrical specifications across connector style, position count, shell size, mounting type, current rating, voltage rating, operating temperature range, contact material, and flange configuration. The connector is a direct form-fit-function replacement.

Q: What is the difference between the various FCE17 part numbers (PC40B, PC41B, PC44B, PC45B, PC48B, PC49B, PC4DB, PC4EB)?

A: All FCE17 variants share identical mechanical and electrical specifications. The suffix designations (PC40B through PC4EB) represent internal Amphenol ICC product configuration codes that do not affect connector performance or compatibility. Selection among these variants is based on inventory availability and internal supply chain requirements.

Q: Are the HARTING 09653226800 and 09653227800 connectors fully compatible with the FCC17B25PC40B?

A: The HARTING connectors are mechanically and electrically compatible across connector style, position count, shell size, mounting configuration, and flange design. However, two parameters differ: backset spacing (0.409" for HARTING versus 0.590" for Amphenol) and contact material (Copper Alloy for HARTING versus Phosphor Bronze for Amphenol). These differences may affect board layout and contact performance in specific applications. Verification of PCB layout compatibility is required before implementation.

Q: What does RoHS compliance mean for connector selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates that the connector meets regulatory requirements restricting lead, cadmium, mercury, and other hazardous materials. The original FCC17B25PC40B is RoHS non-compliant. All substitute parts listed (FCE17 series and HARTING) are RoHS compliant or RoHS3 compliant, meeting current regulatory standards for commercial and industrial applications.

Q: Can I use a HARTING connector in place of an Amphenol connector in a legacy system?

A: Mechanical and electrical compatibility exists across all critical parameters. However, the reduced backset spacing (0.409" versus 0.590") may require PCB layout modification if the original design utilized the full 0.590" spacing for component placement. Contact material differences (Copper Alloy versus Phosphor Bronze) may affect contact resistance and mating force characteristics. Functional testing is recommended for critical applications before full production implementation.

Q: What is the significance of the contact finish thickness specification (15.0µin)?

A: Contact finish thickness of 15.0µin (0.38µm) specifies the gold plating depth on the connector contacts. This thickness ensures adequate contact durability and electrical performance across the rated number of mating cycles. All listed substitute parts maintain this specification, ensuring equivalent contact reliability.

Q: Are there any temperature or current derating considerations when substituting connectors?

A: The FCC17B25PC40B is rated for 5A at an operating temperature range of -40°C to 85°C. The FCE17 series maintains these specifications. The HARTING connectors provide higher current capacity (6.5A) and extended temperature range (-55°C to 125°C), eliminating derating concerns in most applications. However, application-specific thermal and current analysis is required to confirm adequate performance margin.

Q: What is the difference between "Similar Manufacturer Part" and "Parametric Equivalent" designations?

A: Both designations indicate functional compatibility with the main part. "Similar Manufacturer Part" indicates a part from the same manufacturer (Amphenol ICC) with active product status. "Parametric Equivalent" indicates a part meeting all critical electrical and mechanical specifications with minor variations in material composition (such as glass-filled dielectric). Both categories are suitable for direct substitution.
