Substitute Part Grouping Explanation

Substitute parts for the FCC17C37SC49B are grouped into two categories based on parametric equivalence and manufacturer origin:

Category 1: Amphenol ICC FCE17 Series (Direct Parametric Equivalents)

The FCE17C37 series represents direct parametric equivalents manufactured by the same supplier. These parts maintain identical mechanical and electrical specifications including 37 positions, 2-row configuration, shell size 4 (DC, C), through-hole right-angle solder termination, 5A current rating, UL94 V-0 flammability rating, and operating temperature range of -40°C to 85°C. The primary differences are series designation (FCE17 versus FCC17), product status (active versus obsolete), and RoHS compliance status (compliant versus non-compliant). Variants within this series differ only in connector shell coding (SC40B, SC41B, SC44B, SC45B, SC48B, SC4DB, SC4EB), which represent different shell material or finish specifications not detailed in the provided parameters.

Category 2: HARTING D-Sub 37 Position Receptacles (Similar Functional Equivalents)

HARTING part numbers 09644147232 and 09664127600 provide functional equivalence as 37 position D-Sub receptacles with 2-row configuration, shell size 4 (DC, C), through-hole right-angle solder termination, and UL94 V-0 flammability rating. These parts differ in current rating (6.5A to 7.5A versus 5A), backset spacing (0.401" to 0.409" versus 0.590"), contact material (copper alloy versus phosphor bronze), dielectric material composition, and operating temperature range (-55°C to 125°C versus -40°C to 85°C). These differences indicate distinct design families suitable for applications with different environmental and electrical requirements.

Engineering Selection Recommendations

Amphenol ICC FCE17C37 Series Selection

The FCE17C37 series represents the primary substitution path for the obsolete FCC17C37SC49B. All variants within this series (FCE17C37SC49B, FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC44B, FCE17C37SC45B, FCE17C37SC48B, FCE17C37SC4DB, FCE17C37SC4EB) maintain identical electrical and mechanical specifications while offering active product status and RoHS compliance. These parts are manufactured by the same supplier, ensuring design continuity and compatibility with existing connector mating interfaces. The FCE17C37SC49B provides the closest direct equivalent with identical shell coding.

HARTING Alternative Selection

HARTING parts 09644147232 and 09664127600 are suitable for applications where the extended operating temperature range (-55°C to 125°C) and higher current ratings (6.5A to 7.5A) provide design advantages. These parts maintain the same connector position count, row configuration, shell size, mounting type, and termination method. Selection of HARTING alternatives requires confirmation that the different backset spacing (0.401" to 0.409" versus 0.590"), contact material composition, and dielectric material specifications are compatible with the application's mechanical and electrical requirements.

Compliance Considerations

Applications subject to RoHS requirements must transition from the non-compliant FCC17C37SC49B to RoHS-compliant alternatives. The FCE17C37 series provides direct RoHS-compliant equivalents. HARTING parts offer ROHS3 compliance, suitable for applications with enhanced regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37 series parts directly replace the FCC17C37SC49B in existing designs?

A: Yes. The FCE17C37 series maintains identical connector position count (37), row configuration (2), shell size (4/DC/C), mounting type (through-hole right-angle), termination method (solder), current rating (5A), operating temperature range (-40°C to 85°C), and flammability rating (UL94 V-0). The primary differences are product status (active versus obsolete) and RoHS compliance status. Mating interface compatibility is maintained.

Q: What is the difference between the various FCE17C37 shell codes (SC40B, SC41B, SC44B, SC45B, SC48B, SC4DB, SC4EB)?

A: The provided parameters do not specify the technical distinctions between these shell codes. These designations represent different shell material or finish specifications within the FCE17C37 product family. Selection among these variants requires reference to detailed connector specifications or consultation with the manufacturer.

Q: Are HARTING parts 09644147232 and 09664127600 direct replacements for the FCC17C37SC49B?

A: These HARTING parts provide functional equivalence as 37 position D-Sub receptacles with identical connector layout and mounting configuration. However, they differ in backset spacing (0.401" to 0.409" versus 0.590"), current rating (6.5A to 7.5A versus 5A), contact material (copper alloy versus phosphor bronze), and operating temperature range (-55°C to 125°C versus -40°C to 85°C). These differences require application-specific compatibility assessment before substitution.

Q: What is the significance of the backset spacing difference between Amphenol and HARTING parts?

A: Backset spacing defines the distance from the connector mounting surface to the rear of the connector body. The Amphenol FCC17C37SC49B specifies 0.590" (14.99mm) backset spacing, while HARTING alternatives specify 0.401" to 0.409" (10.20mm to 10.40mm). This dimensional difference affects board layout and mechanical clearance requirements. Substitution requires confirmation that the application's printed circuit board design accommodates the different backset spacing.

Q: Does the gold contact finish on Amphenol parts provide advantages over unspecified contact finishes on HARTING parts?

A: The FCC17C37SC49B and all FCE17C37 variants specify gold contact finish at 15.0µin (0.38µm) thickness. HARTING parts do not specify contact finish in the provided parameters. Gold plating provides enhanced corrosion resistance and contact reliability. Applications requiring specific contact finish specifications should select parts with documented gold plating.

Q: Are all substitute parts available in equivalent inventory quantities?

A: Inventory availability varies across substitute parts. The FCC17C37SC49B has 720 pieces in stock. FCE17C37 variants range from 727 to 1119 pieces in stock. HARTING alternatives have 715 to 930 pieces in stock. Procurement decisions should account for current inventory levels and lead time requirements.

Q: What compliance certifications apply to each substitute part?

A: The FCC17C37SC49B is RoHS non-compliant. All FCE17C37 variants are RoHS compliant. HARTING parts 09644147232 and 09664127600 are ROHS3 compliant and REACH unaffected. Applications subject to RoHS or REACH regulations must select compliant alternatives accordingly.
