Engineering Selection Recommendations

Amphenol ICC FCE17 Series (FCE17C37PB45B, FCE17C37PB40B, FCE17C37PB41B, FCE17C37PB44B, FCE17C37PB48B, FCE17C37PB49B, FCE17C37PB4DB, FCE17C37PB4EB)

The FCE17 series represents the direct active-production equivalent to the obsolete FCC17C37PB45B. All FCE17 variants maintain identical electrical and mechanical specifications including 37-position configuration, 5A current rating, -40°C to 85°C operating temperature range, and solder termination. All FCE17 variants are RoHS Compliant and carry Active product status, ensuring long-term availability and supply chain continuity. The FCE17 series is the primary recommendation for direct replacement applications.

HARTING 09654226800 and 09654227800

The HARTING D-Sub 37-position right-angle solder plug connectors (09654226800 and 09654227800) provide functional equivalence with the following distinctions: higher current rating (6.5A versus 5A), extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), and ROHS3 Compliant status. These connectors feature stamped contact construction and unthreaded housing/shell flange design. The HARTING options are suitable for applications requiring enhanced thermal performance or higher current capacity within the same connector form factor.

Compliance Considerations

The original FCC17C37PB45B is RoHS non-compliant. All active substitute options (FCE17 series and HARTING parts) are RoHS Compliant or ROHS3 Compliant. Applications subject to RoHS regulatory requirements must transition to compliant alternatives. The FCE17 series maintains the closest electrical and mechanical alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37PB series connectors directly replace the obsolete FCC17C37PB45B?

A: Yes. The FCE17C37PB series maintains identical electrical and mechanical parameters including 37-position configuration, 5A current rating, -40°C to 85°C operating temperature, and right-angle solder termination. All FCE17 variants are mechanically and electrically interchangeable with the FCC17C37PB45B.

Q: What is the difference between the various FCE17C37PB variants (PB40B, PB41B, PB44B, PB48B, PB49B, PB4DB, PB4EB)?

A: The FCE17C37PB variants differ in suffix designation, which typically indicates internal design or manufacturing process variations. All variants share identical electrical specifications, mechanical dimensions, and performance characteristics. Selection among variants depends on specific design documentation or internal part numbering requirements.

Q: Are HARTING 09654226800 and 09654227800 fully compatible with FCC17C37PB45B?

A: HARTING connectors provide functional equivalence with the following differences: higher current rating (6.5A), extended operating temperature range (-55°C to 125°C), stamped contact construction, and unthreaded housing flange. These differences represent performance enhancements suitable for demanding applications. Mechanical fit and electrical function are compatible within the D-Sub 37-position right-angle solder connector category.

Q: What is the significance of the backset spacing difference between Amphenol (0.405") and HARTING (0.409") connectors?

A: Backset spacing defines the distance from the connector mounting surface to the contact plane. The 0.004" (0.11mm) difference falls within acceptable tolerance for D-Sub connector mating. Both spacing values are compatible with standard D-Sub receptacle connectors. Verify specific PCB layout requirements if backset spacing is a critical design parameter.

Q: Why is the original FCC17C37PB45B marked as obsolete?

A: The FCC17C37PB45B is RoHS non-compliant. Amphenol ICC transitioned to the RoHS Compliant FCE17 series to meet regulatory requirements and market demand. The FCE17 series provides equivalent functionality with regulatory compliance, making it the recommended long-term solution.

Q: Can I use FCE17C37PB connectors in applications originally designed for FCC17C37PB45B?

A: Yes. The FCE17 series is the direct active replacement. All electrical and mechanical specifications are identical. The primary difference is RoHS compliance status, which represents an improvement for regulatory adherence. No design modifications are required.

Q: What is the difference between machined and stamped contact construction?

A: Machined contacts (FCC17C37PB45B, FCE17 series) are individually formed through precision machining, providing consistent contact geometry and higher reliability. Stamped contacts (HARTING 09654226800, 09654227800) are formed through stamping processes, offering cost efficiency while maintaining electrical performance. Both contact types are suitable for signal applications at 5A or higher current ratings.

Q: Are all substitute parts available in the same packaging as the original FCC17C37PB45B?

A: Packaging information is not specified for the FCC17C37PB45B. HARTING parts are available in Bulk packaging. Verify specific packaging requirements with component suppliers, as packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, select from the active FCE17C37PB series (FCE17C37PB45B, FCE17C37PB40B, FCE17C37PB41B, FCE17C37PB44B, FCE17C37PB48B, FCE17C37PB49B, FCE17C37PB4DB, or FCE17C37PB4EB). These connectors offer RoHS compliance, active product status, and long-term supply availability. HARTING alternatives are suitable if extended temperature range or higher current capacity is required.

Q: What is the voltage rating difference between FCC17C37PB45B (200V) and FCE17 variants (not specified)?

A: The original FCC17C37PB45B specifies 200V voltage rating. FCE17 variants do not specify voltage rating in available documentation. For applications with specific voltage requirements, contact the manufacturer or component supplier to confirm voltage rating specifications for FCE17 variants.
