Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Preferred Substitutes)

The FCE17C37SA2DB, FCE17C37SA20B, FCE17C37SA21B, FCE17C37SA24B, FCE17C37SA25B, FCE17C37SA28B, FCE17C37SA29B, and FCE17C37SA2EB connectors are direct parametric equivalents to the obsolete FCC17C37SA2DB. All FCE17 variants maintain identical electrical and mechanical specifications including 37 positions, 2-row configuration, shell size 4 (DC, C), through-hole right-angle solder termination, 5A current rating, 0.318" backset spacing, and -40°C to 85°C operating temperature range. All FCE17 series parts are active products with RoHS compliance, addressing the obsolescence and regulatory compliance limitations of the original FCC17C37SA2DB. The FCE17 series variants differ only in internal contact configuration or flange specifications not affecting basic connector function. Selection among FCE17 variants should be based on specific application requirements and internal contact specifications.

HARTING Alternatives (Secondary Substitutes)

The HARTING 09644147232 and 09664127600 connectors provide functional D-Sub 37 position receptacle alternatives with active product status and ROHS3 compliance. However, these parts differ from the FCC17C37SA2DB in backset spacing (0.401" and 0.409" respectively versus 0.318"), current rating (7.5A and 6.5A versus 5A), and contact material (copper alloy versus phosphor bronze). The HARTING parts support extended operating temperature ranges (-55°C to 125°C) and higher current capacity. These differences require mechanical and electrical design verification before implementation. HARTING alternatives are suitable only when backset spacing and contact material differences are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SA2DB directly replace FCC17C37SA2DB without design changes?

A: Yes. The FCE17C37SA2DB maintains identical electrical and mechanical parameters including connector type, position count, shell size, mounting configuration, termination method, current rating, backset spacing, and operating temperature range. The primary differences are product status (active versus obsolete) and RoHS compliance (compliant versus non-compliant). No design modifications are required for direct substitution.

Q: What is the difference between the various FCE17C37SA variants?

A: All FCE17C37SA variants (SA2DB, SA20B, SA21B, SA24B, SA25B, SA28B, SA29B, SA2EB) share identical external dimensions, electrical ratings, and mechanical specifications. Variants differ in internal contact configuration or flange specifications. Selection should be based on specific application requirements and internal contact specifications documented in detailed product datasheets.

Q: Why do HARTING parts have different backset spacing?

A: Backset spacing is a dimensional parameter that defines the distance from the connector mounting surface to the contact plane. HARTING 09644147232 (0.401") and 09664127600 (0.409") differ from the FCC17C37SA2DB (0.318") due to different internal mechanical designs. This difference affects PCB layout and mating connector compatibility. HARTING alternatives require verification that the increased backset spacing is compatible with the target application's mechanical constraints.

Q: Are HARTING connectors compatible with Amphenol ICC connectors?

A: HARTING 09644147232 and 09664127600 are D-Sub 37 position receptacles with the same shell size and pin configuration as the FCC17C37SA2DB. However, the different backset spacing (0.401" and 0.409" versus 0.318") may affect mating with standard D-Sub plugs designed for the original backset spacing. Mechanical compatibility must be verified before implementation.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the connector meets regulatory requirements restricting lead, cadmium, mercury, and other hazardous materials. The FCC17C37SA2DB is RoHS non-compliant, while all FCE17 variants and HARTING alternatives are RoHS or ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, compliant alternatives are mandatory.

Q: Can I use a higher current-rated connector (HARTING 7.5A or 6.5A) in place of the 5A FCC17C37SA2DB?

A: Higher current ratings provide additional safety margin and are generally compatible with applications designed for 5A operation. However, the different backset spacing in HARTING parts requires mechanical verification. If backset spacing is compatible with the application, the higher current rating of HARTING alternatives presents no technical limitation.

Q: What inventory levels are available for these substitute parts?

A: Current inventory levels are: FCE17C37SA2DB (780 pcs), FCE17C37SA20B (824 pcs), FCE17C37SA21B (909 pcs), FCE17C37SA24B (712 pcs), FCE17C37SA25B (1071 pcs), FCE17C37SA28B (949 pcs), FCE17C37SA29B (989 pcs), FCE17C37SA2EB (912 pcs), HARTING 09644147232 (715 pcs), and HARTING 09664127600 (930 pcs). Inventory levels are subject to change and should be confirmed at time of procurement.

Q: Are there any temperature range limitations when substituting with HARTING parts?

A: The FCC17C37SA2DB operates from -40°C to 85°C. HARTING alternatives support -55°C to 125°C, providing a wider operating range. For applications within the original -40°C to 85°C range, HARTING parts are fully compatible. For applications requiring extended temperature operation, HARTING alternatives provide additional capability.
