Engineering Selection Recommendations

Primary Substitute: FCE17C37SA44B (Amphenol ICC)

The FCE17C37SA44B is the direct active equivalent from the same manufacturer. This part maintains identical electrical and mechanical specifications to the FCC17C37SA44B while offering active product status and RoHS compliance. The FCE17 series represents the current production line replacement for the obsolete FCC17 series. Selection of this part eliminates supply chain risk associated with obsolete components.

Secondary Substitutes: HARTING 09664 Series

The HARTING D-Sub 37 position receptacle connectors (09664127600, 09664127601, 09664136602, 09664526611, 09664527610, 09664527611, 09664566610, 09664566612) provide functional equivalence with the following considerations:

All HARTING substitutes maintain the critical parameters of 37 position, 2-row, shell size 4 (DC, C), through-hole right-angle solder termination, and UL94 V-0 flammability rating. These parts are active products with ROHS3 compliance status.

HARTING parts feature a higher current rating of 6.5A compared to the 5A rating of the main part, providing operational margin. Operating temperature range extends to -55°C to 125°C, exceeding the original -40°C to 85°C specification.

Selection among HARTING variants depends on flange feature requirements:

09664127600: Unthreaded housing/shell flange
09664127601: M3 threaded housing/shell flange
09664136602: 4-40 threaded housing/shell flange
09664526611: M3 flange with board lock feature
09664527610: Unthreaded flange with board lock feature
09664527611: M3 flange with board lock feature
09664566610: Unthreaded flange with board lock feature and PCT dielectric
09664566612: 4-40 flange with board lock feature and PCT dielectric

The original FCC17C37SA44B features a board-side 4-40 flange. For direct mechanical compatibility, HARTING part 09664136602 provides equivalent 4-40 flange mounting. Parts with board lock features (09664526611, 09664527610, 09664527611, 09664566610, 09664566612) offer enhanced retention but require board design accommodation.

Compliance Considerations

The main part FCC17C37SA44B is RoHS non-compliant. All substitute parts listed are RoHS compliant (FCE17C37SA44B: RoHS Compliant; HARTING series: ROHS3 Compliant). For applications subject to RoHS requirements, any listed substitute satisfies regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SA44B directly replace the FCC17C37SA44B without board redesign?

A: Yes. The FCE17C37SA44B maintains identical electrical and mechanical specifications, including flange type (board-side 4-40), mounting orientation (through-hole right-angle), and termination method (solder). No board redesign is required.

Q: What is the primary difference between the FCC17 and FCE17 series?

A: The FCE17 series is the active production equivalent of the obsolete FCC17 series. Both series share identical connector specifications. The FCE17 series offers RoHS compliance and active product status, eliminating obsolescence risk.

Q: Are HARTING substitutes mechanically compatible with the original FCC17C37SA44B?

A: HARTING substitutes maintain identical connector geometry, shell size, position count, and mounting type. However, flange feature differences require attention. The original part features a board-side 4-40 flange. HARTING part 09664136602 provides equivalent 4-40 flange mounting. Other HARTING variants feature housing/shell flanges with different fastening options (unthreaded, M3, or 4-40) and may require board modification.

Q: What is the significance of the board lock feature on certain HARTING parts?

A: Board lock features (present on 09664526611, 09664527610, 09664527611, 09664566610, 09664566612) provide mechanical retention of the connector to the PCB. The original FCC17C37SA44B does not include this feature. Selection of board lock variants requires board design accommodation for the locking mechanism.

Q: How do current ratings differ between the main part and substitutes?

A: The FCC17C37SA44B is rated for 5A. All HARTING substitutes are rated for 6.5A. The FCE17C37SA44B maintains the 5A rating. For applications operating at or near the 5A limit, the higher HARTING rating provides operational margin. For applications with lower current requirements, both ratings are acceptable.

Q: What is the difference between PBT and PCT dielectric materials used in HARTING parts?

A: Both materials are glass-filled thermoplastic compounds meeting UL94 V-0 flammability requirements. PBT (Polybutylene Terephthalate) is used in parts 09664127600, 09664127601, 09664136602, 09664526611, 09664527610, and 09664527611. PCT (Polycyclohexylenedimethylene Terephthalate) is used in parts 09664566610, 09664566611, and 09664566612. Both materials satisfy the electrical and mechanical requirements for D-Sub receptacle applications.

Q: Is RoHS compliance required for my application?

A: The original FCC17C37SA44B is RoHS non-compliant. If your application or market requires RoHS compliance, select the FCE17C37SA44B (RoHS Compliant) or any HARTING substitute (ROHS3 Compliant). All listed substitutes meet current RoHS requirements.

Q: What is the operating temperature range difference between the main part and HARTING substitutes?

A: The FCC17C37SA44B operates from -40°C to 85°C. HARTING substitutes operate from -55°C to 125°C. For applications within the original temperature range, both specifications are acceptable. For applications requiring extended temperature operation, HARTING substitutes provide additional margin.

Q: How do I select the correct HARTING flange variant?

A: Flange selection depends on your PCB mounting requirements. If your board is designed for 4-40 threaded fasteners (matching the original part), select 09664136602 or 09664566612. If your board uses M3 fasteners, select 09664127601, 09664526611, 09664527611, or 09664566611. If your board uses unthreaded mounting, select 09664127600, 09664527610, or 09664566610. If board lock retention is required, select from the board lock variants (09664526611, 09664527610, 09664527611, 09664566610, 09664566612).

Q: Can I use a substitute part with a different flange type if I modify my board?

A: Yes. All listed substitutes maintain identical connector electrical and mechanical specifications. Board modification to accommodate different flange types is an engineering decision based on your specific design requirements and manufacturing capabilities.

Q: What inventory levels are available for each substitute?

A: Inventory availability is subject to change. Current stock levels are: FCE17C37SA44B (739 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).
