Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17C37SA640, FCE17C37SA600, FCE17C37SA610, FCE17C37SA650, FCE17C37SA680, FCE17C37SA690, FCE17C37SA6D0, and FCE17C37SA6E0 represent the optimal substitutes for the obsolete FCC17C37SA640. These parts maintain complete parametric equivalence across all critical mechanical and electrical specifications while offering the following advantages:

Active product status with ongoing manufacturer support
RoHS compliance for regulatory adherence
Identical connector geometry and pin configuration
Matching current and voltage ratings
Equivalent operating temperature range
Identical shell material and contact finish specifications
Consistent flammability certification (UL94 V-0)

Secondary Recommendation: HARTING Cross-Manufacturer Alternatives

The HARTING 09644147232 and 09664127600 connectors provide functional alternatives with the following considerations:

HARTING 09644147232:

Maintains 37 position, 2 row D-Sub receptacle configuration
Exceeds current rating (7.5A vs. 5A)
Extended operating temperature range (-55°C to 125°C)
Increased backset spacing (0.401" vs. 0.318") requires PCB layout verification
ROHS3 compliance

HARTING 09664127600:

Maintains 37 position, 2 row D-Sub receptacle configuration
Exceeds current rating (6.5A vs. 5A)
Extended operating temperature range (-55°C to 125°C)
Increased backset spacing (0.409" vs. 0.318") requires PCB layout verification
Stamped contact form differs from machined contacts
ROHS3 compliance

Cross-manufacturer substitution requires verification of PCB mounting hole spacing and mechanical clearances due to backset spacing differences.

Frequently Asked Questions (FAQ)

Q1: Can the FCE17C37SA640 directly replace the FCC17C37SA640 without design modifications?

A: Yes. The FCE17C37SA640 maintains identical specifications across all critical parameters including connector type, position count, shell size, mounting configuration, current rating, voltage rating, operating temperature range, and flammability certification. The primary difference is product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

Q2: What is the significance of the different FCE17 part number suffixes (SA600, SA610, SA650, SA680, SA690, SA6D0, SA6E0)?

A: The suffix variations indicate different internal contact or configuration options within the FCE17C37 base product line. All listed variants maintain identical external mechanical specifications and electrical ratings. The specific suffix selection depends on internal circuit requirements not specified in the provided parameters.

Q3: Why do the HARTING connectors have different backset spacing values?

A: Backset spacing refers to the distance from the connector mounting surface to the rear of the connector body. The HARTING 09644147232 (0.401") and 09664127600 (0.409") have increased spacing compared to the Amphenol ICC parts (0.318"). This difference requires verification against PCB layout and mechanical clearance requirements before substitution.

Q4: Are the HARTING connectors suitable for applications requiring the exact 200V rating of the FCC17C37SA640?

A: The HARTING 09644147232 specifies a 100V rating, which is lower than the original 200V specification. The HARTING 09664127600 does not specify a voltage rating. For applications requiring 200V operation, the Amphenol ICC FCE17 series is the appropriate choice.

Q5: What is the impact of RoHS compliance on connector selection?

A: RoHS compliance affects material composition and manufacturing processes. The FCE17 series offers RoHS compliance, making these parts suitable for applications subject to RoHS regulations. The original FCC17C37SA640 is RoHS non-compliant. Selection depends on regulatory requirements for the end application.

Q6: Can the extended operating temperature range of HARTING connectors (-55°C to 125°C) be used as a direct upgrade?

A: The extended temperature range represents a capability enhancement but does not affect compatibility for applications operating within the original -40°C to 85°C range. Selection should be based on actual application requirements rather than specification expansion.

Q7: What is the difference between machined and stamped contact forms?

A: The FCC17C37SA640 and FCE17 series use machined contacts, while the HARTING 09664127600 uses stamped contacts. Machined contacts typically provide higher precision and consistency. This difference may affect contact resistance and reliability characteristics in high-reliability applications.

Q8: Are all listed substitute parts available in equivalent inventory quantities?

A: Inventory levels vary. The FCE17C37SA640 has 747 units in stock, while other FCE17 variants range from 824 to 999 units. HARTING parts have 715 and 930 units respectively. Availability should be confirmed for production requirements.

Q9: What certifications apply to all substitute parts?

A: All listed parts carry UL94 V-0 flammability certification. The Amphenol ICC FCE17 series is RoHS compliant. The HARTING parts are ROHS3 compliant and REACH unaffected. Specific application requirements may necessitate additional certifications.

Q10: How should backset spacing differences be evaluated for PCB compatibility?

A: Backset spacing affects the distance between the PCB mounting surface and the connector body rear. Increased spacing (HARTING parts) may interfere with components or enclosure features positioned behind the connector. PCB layout drawings and mechanical clearance analysis are required before cross-manufacturer substitution.
