Substitution Categories:

Category 1: Direct Series Equivalents (Amphenol ICC FCE17 Series) The FCE17C37SC64B, FCE17C37SC60B, FCE17C37SC61B, FCE17C37SC65B, FCE17C37SC68B, FCE17C37SC69B, FCE17C37SC6DB, and FCE17C37SC6EB represent active production equivalents within the Amphenol ICC product line. These parts maintain identical mechanical and electrical specifications to the FCC17C37SC64B while offering RoHS compliance and active product status. Differences in the suffix designations (64B, 60B, 61B, 65B, 68B, 69B, 6DB, 6EB) reflect internal manufacturing or configuration variations that do not affect functional compatibility.

Category 2: Cross-Manufacturer Alternatives (HARTING) The HARTING 09644147232 and 09664127600 connectors provide functional substitution with variations in specific parameters. These parts maintain the core D-Sub 37 position receptacle configuration, through-hole right-angle mounting, and solder termination. Parameter variations include backset spacing, current rating, voltage rating, contact form, and dielectric material composition. These differences require engineering evaluation for specific application requirements.

Engineering Selection Recommendations

Amphenol ICC FCE17 Series (FCE17C37SC64B, FCE17C37SC60B, FCE17C37SC61B, FCE17C37SC65B, FCE17C37SC68B, FCE17C37SC69B, FCE17C37SC6DB, FCE17C37SC6EB)

The FCE17 series represents the primary substitution path for the obsolete FCC17C37SC64B. All eight variants maintain identical mechanical and electrical specifications while offering active product status and RoHS compliance. The FCE17C37SC64B provides the closest direct equivalent with identical part number structure. These parts are suitable for applications requiring RoHS-compliant components and where ongoing component availability is critical. The glass-filled thermoplastic dielectric material in the FCE17 series provides enhanced mechanical properties compared to the unfilled thermoplastic of the original part.

HARTING 09644147232

This connector provides functional substitution with the following considerations: higher current rating (7.5A versus 5A), extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), and different backset spacing (0.401" versus 0.590"). The part features board lock functionality and PCT dielectric material. This option is suitable for applications requiring enhanced thermal performance or higher current capacity, provided that the reduced backset spacing is compatible with the printed circuit board layout.

HARTING 09664127600

This connector offers functional substitution with higher current rating (6.5A versus 5A) and extended operating temperature range (-55°C to 125°C). The backset spacing is 0.409" compared to 0.590", and the dielectric material is PBT with glass fill. This option is appropriate for applications requiring improved thermal performance, provided that the backset spacing variation is accommodated in the circuit board design.

Compliance Considerations

Applications subject to RoHS regulations must transition from the non-compliant FCC17C37SC64B to one of the RoHS-compliant alternatives. The Amphenol ICC FCE17 series provides direct RoHS compliance. HARTING parts offer ROHS3 compliance, which encompasses RoHS 2 and RoHS 3 requirements.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SC64B directly replace the FCC17C37SC64B without any modifications?

A: Yes. The FCE17C37SC64B maintains identical mechanical and electrical specifications to the FCC17C37SC64B. The part is a direct functional equivalent with active product status and RoHS compliance. No circuit board modifications or connector interface changes are required.

Q: What is the difference between the various FCE17 suffix designations (60B, 61B, 65B, 68B, 69B, 6DB, 6EB)?

A: The suffix designations reflect internal manufacturing or configuration variations within the Amphenol ICC product line. All variants maintain identical electrical and mechanical specifications relevant to connector function and compatibility. Selection among these variants should be based on component availability and internal manufacturing specifications provided by Amphenol ICC.

Q: Are the HARTING connectors (09644147232 and 09664127600) fully compatible with the FCC17C37SC64B?

A: The HARTING connectors provide functional substitution for the core D-Sub 37 position receptacle application. However, they differ in backset spacing (0.401" and 0.409" respectively versus 0.590"), which affects the distance from the connector mounting surface to the contact plane. This variation requires verification that the printed circuit board layout accommodates the different backset spacing. Additionally, the HARTING parts feature different dielectric materials and higher current ratings, which may be advantageous for specific applications but require confirmation that these differences align with system requirements.

Q: What is backset spacing and why does it matter?

A: Backset spacing is the distance from the rear mounting surface of the connector to the contact plane. The FCC17C37SC64B has a backset spacing of 0.590" (14.99mm), while the HARTING alternatives have 0.401" (10.20mm) and 0.409" (10.40mm) respectively. This dimension is critical for printed circuit board design, as it determines the depth of the connector cavity and the clearance available for internal components. Substituting a connector with different backset spacing requires verification that the circuit board layout can accommodate the dimensional change.

Q: Is RoHS compliance mandatory for my application?

A: RoHS compliance is mandatory for products sold in the European Union and many other jurisdictions. If your application is subject to RoHS regulations, the FCC17C37SC64B (RoHS non-compliant) must be replaced with a RoHS-compliant alternative such as the FCE17 series or HARTING ROHS3-compliant options. Consult your regulatory requirements and customer specifications to determine if RoHS compliance is necessary.

Q: What is the difference between the contact materials used in these connectors?

A: The FCC17C37SC64B and all FCE17 variants use phosphor bronze contacts with gold plating (15.0µin thickness). The HARTING connectors use copper alloy contacts with unspecified finish. Phosphor bronze provides superior corrosion resistance and contact reliability compared to unfinished copper alloy. The gold plating on the Amphenol ICC parts provides additional protection against oxidation and ensures consistent contact resistance over the connector's operational life.

Q: Can I use the HARTING connectors in applications with the original operating temperature range of -40°C to 85°C?

A: Yes. The HARTING connectors are rated for -55°C to 125°C, which encompasses the original -40°C to 85°C range. The extended temperature rating provides additional margin and does not restrict use in applications within the original temperature specification.

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

A: Current inventory levels are: FCC17C37SC64B (708 pcs), FCE17C37SC64B (690 pcs), FCE17C37SC60B (846 pcs), FCE17C37SC61B (742 pcs), FCE17C37SC65B (767 pcs), FCE17C37SC68B (667 pcs), FCE17C37SC69B (666 pcs), FCE17C37SC6DB (924 pcs), FCE17C37SC6EB (870 pcs), 09644147232 (715 pcs), and 09664127600 (930 pcs). Inventory levels are subject to change and should be confirmed with the component supplier for current availability.

Q: Are there any mechanical mounting differences between these connectors?

A: All connectors feature through-hole, right-angle mounting with board-side flanges. The Amphenol ICC parts use M3 flange mounting, while the HARTING 09644147232 uses 4-40 housing/shell mounting and the 09664127600 uses unthreaded housing/shell mounting. These differences affect the fastening method used to secure the connector to the circuit board. Verify that your circuit board design accommodates the specific flange mounting style of the selected connector.
