Engineering Selection Recommendations

Primary Substitute: FCE17C37SA4EB (Amphenol ICC)

The FCE17C37SA4EB is the direct active-production equivalent from Amphenol ICC. This part maintains identical electrical and mechanical specifications to the FCC17C37SA4EB, including 37 positions, 2-row configuration, 5A current rating, and -40°C to 85°C operating temperature range. The FCE17C37SA4EB is RoHS Compliant and carries Active product status with 685 pieces in stock. The primary difference is the flange feature location (Housing/Shell versus Board Side), which does not affect functional compatibility. This substitute is recommended for direct replacement in applications requiring Amphenol ICC connectors.

Secondary Substitutes: HARTING 09664127600, 09664127601, 09664136602, 09664526611, 09664527610, 09664527611, 09664566610, 09664566612

All HARTING substitutes maintain the critical 37-position, 2-row D-Sub receptacle configuration with through-hole, right-angle solder termination and UL94 V-0 flammability rating. These parts are ROHS3 Compliant with Active product status. HARTING substitutes feature higher current ratings (6.5A versus 5A) and extended operating temperature ranges (-55°C to 125°C versus -40°C to 85°C), providing enhanced performance margins. Backset spacing differs at 0.409" (10.40mm) compared to the original 0.318" (8.08mm), which may require PCB layout verification. Contact form varies between Stamped (HARTING) and Machined (original), and dielectric materials differ between Polybutylene Terephthalate (PBT) and Polycyclohexylenedimethylene Terephthalate (PCT) formulations. HARTING parts with Board Lock features (09664526611, 09664527610, 09664527611, 09664566610, 09664566612) provide additional mechanical retention. Selection among HARTING variants depends on specific flange feature requirements (Unthreaded, M3, or 4-40) and Board Lock necessity.

Compliance Considerations:

The original FCC17C37SA4EB is RoHS non-compliant. All active substitute options (FCE17C37SA4EB and all HARTING variants) are RoHS Compliant or ROHS3 Compliant, meeting current regulatory requirements for new designs and manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SA4EB directly replace the FCC17C37SA4EB?

A: Yes. The FCE17C37SA4EB is functionally equivalent with identical connector configuration, position count, current rating, and operating temperature range. The flange feature differs (Housing/Shell versus Board Side), but both use 4-40 mounting holes and maintain mechanical compatibility. Verify PCB mounting hole alignment before installation.

Q: What is the primary difference between Amphenol ICC and HARTING substitutes?

A: Amphenol ICC (FCE17C37SA4EB) maintains the original 5A current rating and 0.318" backset spacing. HARTING substitutes provide 6.5A current rating and 0.409" backset spacing, requiring PCB layout verification. HARTING parts also feature extended operating temperature range (-55°C to 125°C) and stamped contacts versus machined contacts in the original design.

Q: Are HARTING substitutes compatible with existing PCB designs?

A: HARTING substitutes differ in backset spacing (0.409" versus 0.318"), which affects the distance from the connector mounting surface to the contact insertion point. PCB layout must be verified to confirm adequate clearance and proper component placement. Flange feature variations (Unthreaded, M3, or 4-40) also require confirmation of mounting hole compatibility.

Q: Which HARTING variant should I select?

A: Selection depends on flange feature requirements: 09664127600 (Unthreaded), 09664127601 (M3), or 09664136602 (4-40) for standard applications. For applications requiring mechanical retention, select variants with Board Lock feature: 09664526611 (M3), 09664527610 (Unthreaded), 09664527611 (M3), 09664566610 (Unthreaded), or 09664566612 (4-40).

Q: Is RoHS compliance required for my application?

A: The original FCC17C37SA4EB is RoHS non-compliant. All active substitutes are RoHS Compliant or ROHS3 Compliant. If your application or market requires RoHS compliance, select from active substitute options. The FCE17C37SA4EB and all HARTING variants meet current RoHS requirements.

Q: What is the difference between Polybutylene Terephthalate (PBT) and Polycyclohexylenedimethylene Terephthalate (PCT) dielectric materials?

A: Both materials are glass-filled thermoplastics with UL94 V-0 flammability rating. PCT (used in 09664566610, 09664566611, 09664566612) provides enhanced thermal and chemical resistance compared to PBT. Selection depends on specific environmental exposure and operating conditions in your application.

Q: Can I use a substitute with higher current rating (6.5A) in place of the original 5A rating?

A: Yes. A higher current rating indicates the substitute can safely handle greater current loads. If your application operates at or below 5A, a 6.5A-rated substitute provides additional performance margin and is functionally compatible.

Q: What does Board Lock feature provide?

A: Board Lock feature (present in HARTING variants 09664526611, 09664527610, 09664527611, 09664566610, 09664566612) provides mechanical retention of the connector to the PCB, preventing accidental disconnection. This feature is optional and depends on application requirements for vibration resistance or mechanical robustness.

Q: Are there inventory considerations for substitute selection?

A: Current inventory levels are: FCC17C37SA4EB (804 pcs), FCE17C37SA4EB (685 pcs), 09664127600 (930 pcs), 09664127601 (1093 pcs), 09664136602 (718 pcs), 09664526611 (1053 pcs), 09664527610 (1002 pcs), 09664527611 (808 pcs), 09664566610 (992 pcs), 09664566611 (656 pcs), 09664566612 (954 pcs). All substitutes maintain adequate stock levels for production requirements.
