Substitute Part Grouping Explanation
Substitution of the FCC17C37SC4DB is determined by strict equivalence across the following critical parameters:
Primary Substitution Criteria:
- Connector style (D-Sub)
- Connector type (Receptacle, Female Sockets)
- Number of positions (37)
- Number of rows (2)
- Shell size and layout (4 / DC, C)
- Mounting type (Through Hole, Right Angle)
- Termination method (Solder)
- Flange feature type (Board Side with 4-40 mounting)
- Contact type (Signal)
- Material flammability rating (UL94 V-0)
- Backset spacing (0.590" / 14.99mm)
Secondary Compatibility Parameters:
- Current rating (5A minimum)
- Operating temperature range (-40°C to 85°C minimum)
- Contact material (Phosphor Bronze or equivalent copper alloy)

Engineering Selection Recommendations
Primary Substitutes (Amphenol ICC FCE17 Series):
The FCE17C37SC4DB, FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC44B, FCE17C37SC45B, FCE17C37SC48B, FCE17C37SC49B, and FCE17C37SC4EB represent direct parametric equivalents to the obsolete FCC17C37SC4DB. All FCE17 variants maintain identical mechanical dimensions, electrical ratings, and functional specifications while offering the advantage of active product status and RoHS compliance. These parts are manufactured by the same supplier (Amphenol ICC) and are suitable for direct substitution in applications where RoHS compliance is required or preferred.
Secondary Alternatives (HARTING):
The HARTING parts 09644147232 and 09664127600 provide functional alternatives that satisfy the core mechanical and electrical requirements. These connectors differ in the following aspects:
- Backset spacing: 0.401" (10.20mm) and 0.409" (10.40mm) respectively, compared to 0.590" (14.99mm) for the main part
- Flange feature: Housing/Shell mounted rather than Board Side mounted
- Current rating: 7.5A and 6.5A respectively, exceeding the 5A specification
- Operating temperature: Extended range of -55°C to 125°C
- Contact finish: Not specified (differs from gold-plated specification)
- Dielectric material: PCT or PBT-based compositions rather than thermoplastic
HARTING alternatives are suitable only when mechanical layout accommodates the different backset spacing and flange mounting configuration, and when the unspecified contact finish is acceptable for the application.
Compliance Considerations:
All substitute parts maintain UL94 V-0 flammability rating. The FCE17 series provides RoHS compliance, addressing regulatory requirements that may have driven the obsolescence of the original FCC17C37SC4DB. HARTING parts carry ROHS3 compliance and REACH unaffected status, providing additional environmental compliance documentation.
Frequently Asked Questions (FAQ)
Q: Can FCE17C37SC4DB be used as a direct replacement for FCC17C37SC4DB?
A: Yes. The FCE17C37SC4DB is a direct parametric equivalent. It maintains identical connector geometry, electrical ratings, mounting configuration, and contact specifications. The primary differences are active product status and RoHS compliance.
Q: What is the difference between the various FCE17 part numbers (SC40B, SC41B, SC44B, SC45B, SC48B, SC49B, SC4EB)?
A: All FCE17 variants share identical mechanical and electrical specifications as listed in the parameter comparison table. The alphanumeric suffix variations (40B, 41B, 44B, 45B, 48B, 49B, 4EB) represent internal Amphenol ICC coding that does not affect functional equivalence for substitution purposes.
Q: Can HARTING parts 09644147232 or 09664127600 be used as substitutes?
A: HARTING parts are functionally compatible alternatives only if the application can accommodate the different backset spacing (0.401" or 0.409" versus 0.590") and Housing/Shell flange mounting rather than Board Side mounting. The unspecified contact finish also requires verification against application requirements.
Q: What is backset spacing and why does it matter?
A: Backset spacing is the distance from the rear of the connector shell to the mounting flange. The FCC17C37SC4DB specifies 0.590" (14.99mm). HARTING alternatives use 0.401" (10.20mm) or 0.409" (10.40mm), which affects PCB layout and mechanical clearance. Substitution requires confirmation that the printed circuit board design accommodates the different spacing.
Q: What is the difference between Board Side and Housing/Shell flange mounting?
A: Board Side flange mounting (FCC17C37SC4DB and FCE17 series) positions the mounting holes on the connector's side flanges, securing the connector directly to the PCB edge. Housing/Shell mounting (HARTING alternatives) positions mounting features on the connector housing itself. These configurations require different PCB cutout designs and mechanical support structures.
Q: Are all substitute parts RoHS compliant?
A: The FCE17 series (all variants) is RoHS compliant. The original FCC17C37SC4DB is RoHS non-compliant. HARTING parts carry ROHS3 compliance. RoHS compliance status should be verified against specific application and regulatory requirements.
Q: What is the significance of the contact finish thickness specification?
A: The FCC17C37SC4DB and all FCE17 variants specify 15.0µin (0.38µm) gold contact finish thickness. This specification ensures consistent electrical contact resistance and corrosion protection. HARTING alternatives do not specify contact finish thickness, requiring verification that their contact plating meets application requirements.
Q: Can I use a substitute part with a higher current rating?
A: HARTING parts offer 7.5A and 6.5A current ratings compared to the 5A specification of the original part. Higher current ratings provide additional margin but do not affect substitution compatibility. The application circuit design determines whether the higher rating is beneficial or irrelevant.
Q: What does "active product status" mean?
A: Active product status indicates that the manufacturer continues to produce and support the part. The FCC17C37SC4DB is classified as obsolete, meaning Amphenol ICC no longer manufactures it. All FCE17 variants and HARTING alternatives maintain active status, ensuring ongoing availability and technical support.
Q: Are there any voltage rating differences between substitutes?
A: The FCC17C37SC4DB specifies 200V. Most FCE17 variants do not specify voltage rating in the provided data. HARTING part 09644147232 specifies 100V. For applications requiring the full 200V rating, the original specification should be confirmed with the substitute manufacturer before selection.
