Engineering Selection Recommendations

Primary Substitute: FCE17C37SA6DB (Amphenol ICC)

The FCE17C37SA6DB is the direct equivalent from the same manufacturer. It maintains identical electrical and mechanical specifications to the FCC17C37SA6DB while offering active product status and RoHS compliance. This part is the preferred substitute for direct replacement in new designs and legacy system updates.

Secondary Substitutes: HARTING 37 Position D-Sub Receptacles

The HARTING series (09664127600, 09664127601, 09664136602, 09664526611, 09664527610, 09664527611, 09664566610, 09664566611, 09664566612) provides functional equivalence with the following considerations:

All HARTING parts maintain the mandatory D-Sub receptacle configuration with 37 positions, 2 rows, shell size 4, through-hole right-angle solder termination, and UL94 V-0 flammability rating. All HARTING parts are active products with ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C).

Mechanical Variation: HARTING parts feature 0.409" (10.40mm) backset spacing compared to the FCC17C37SA6DB specification of 0.318" (8.08mm). This difference affects PCB layout and connector positioning. Selection between HARTING variants depends on flange feature requirements:

Unthreaded Housing/Shell: 09664127600, 09664527610, 09664566610
M3 Housing/Shell: 09664127601, 09664526611, 09664527611, 09664566611
4-40 Housing/Shell: 09664136602, 09664566612

Board Lock Feature: HARTING parts 09664526611, 09664527610, 09664527611, 09664566610, 09664566611, and 09664566612 include board lock functionality. Parts 09664127600, 09664127601, and 09664136602 do not include this feature.

Dielectric Material Variation: HARTING parts 09664127600, 09664127601, and 09664136602 use Polybutylene Terephthalate (PBT) dielectric. HARTING parts 09664526611, 09664527610, 09664527611 use Polybutylene Terephthalate (PBT) dielectric. HARTING parts 09664566610, 09664566611, and 09664566612 use Polycyclohexylenedimethylene Terephthalate (PCT) dielectric.

Electrical Upgrade: All HARTING substitutes provide 6.5A current rating compared to the FCC17C37SA6DB 5A rating, representing increased electrical capacity.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SA6DB directly replace FCC17C37SA6DB in existing designs?

A: Yes. The FCE17C37SA6DB maintains identical connector specifications including shell size, position count, mounting type, termination method, and electrical ratings. The primary difference is product status (active versus obsolete) and RoHS compliance status.

Q: What is the significance of the backset spacing difference between FCC17C37SA6DB (0.318") and HARTING substitutes (0.409")?

A: Backset spacing defines the distance from the mounting flange to the rear of the connector shell. The 0.409" spacing in HARTING parts requires different PCB layout and mounting hole positioning compared to the original 0.318" specification. Physical validation of PCB clearances and mounting hole alignment is necessary before implementation.

Q: Are HARTING D-Sub receptacles electrically compatible with the FCC17C37SA6DB?

A: Yes. All HARTING substitutes maintain the same D-Sub 37 position, 2-row configuration with signal contact type and UL94 V-0 flammability rating. The 6.5A current rating in HARTING parts exceeds the 5A rating of the FCC17C37SA6DB, providing equal or superior electrical capacity for signal transmission.

Q: What is the difference between HARTING parts with and without board lock features?

A: Board lock features (present in 09664526611, 09664527610, 09664527611, 09664566610, 09664566611, 09664566612) provide mechanical retention of the connector to the PCB. Parts without board lock (09664127600, 09664127601, 09664136602) rely on solder termination alone for mechanical attachment. Selection depends on application requirements for connector retention and serviceability.

Q: How do flange feature variations affect connector selection?

A: Flange features determine the mounting interface. Unthreaded housing/shell flanges provide basic mounting. M3 threaded flanges accommodate M3 fasteners for additional mechanical security. 4-40 threaded flanges accommodate 4-40 fasteners. Selection depends on the mounting structure and fastening requirements of the target application.

Q: Is the extended operating temperature range of HARTING parts (-55°C ~ 125°C) a concern for FCC17C37SA6DB replacement?

A: No. The extended temperature range in HARTING parts represents a capability enhancement. If the original application operates within -40°C ~ 85°C, HARTING parts with -55°C ~ 125°C rating provide equal performance within that range with additional margin for temperature extremes.

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

A: Both materials maintain UL94 V-0 flammability rating and are glass-filled thermoplastics. PCT offers enhanced thermal and chemical resistance compared to PBT. For applications within the specified operating temperature range, both materials are functionally equivalent.

Q: Can I use HARTING 09664566611 (obsolete) as a substitute for FCC17C37SA6DB?

A: The 09664566611 is classified as obsolete, similar to the FCC17C37SA6DB. While it maintains functional equivalence, active alternatives (09664566610, 09664566612) are preferred for new designs and long-term procurement continuity.

Q: What RoHS compliance status should I specify for new designs?

A: The FCC17C37SA6DB is RoHS non-compliant. For new designs, FCE17C37SA6DB (RoHS Compliant) or any HARTING substitute (ROHS3 Compliant) is recommended to meet current regulatory requirements.
