Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCC17C37SM450 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• 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 (Free Hanging / In-Line)
• Termination method (Solder Cup)
• Current rating (5A)
• Operating temperature range (-40°C ~ 85°C)
• Shell material and finish (Steel, Tin Plated)
• Contact material (Phosphor Bronze)
• Flange feature (Cable Side with 4-40 specification)

The FCE17C37SM450 maintains full compatibility across all critical parameters while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FCE17C37SM450 serves as the direct functional equivalent to the obsolete FCC17C37SM450. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, current and voltage ratings, and operating temperature range.

The FCE17C37SM450 offers two significant advantages for new designs and production transitions:

Product Status: The FCE17C37SM450 maintains active product status, ensuring continued availability and manufacturer support, whereas the FCC17C37SM450 is classified as obsolete.

Regulatory Compliance: The FCE17C37SM450 is RoHS compliant, meeting current environmental and regulatory requirements. The FCC17C37SM450 is RoHS non-compliant. Additionally, the FCE17C37SM450 incorporates a glass-filled thermoplastic dielectric material, providing enhanced mechanical and thermal stability compared to the standard thermoplastic used in the FCC17C37SM450.

Selection of the FCE17C37SM450 is appropriate for all applications previously served by the FCC17C37SM450, with no functional or mechanical redesign required.

Frequently Asked Questions (FAQ)

Q: Are the FCC17C37SM450 and FCE17C37SM450 mechanically interchangeable?

A: Yes. Both connectors share identical shell size (4 / DC, C), mounting configuration (Free Hanging / In-Line), flange design (Cable Side with 4-40 specification), and contact arrangement (37 positions in 2 rows). No mechanical modifications are required for substitution.

Q: Do these connectors have the same electrical ratings?

A: Yes. Both connectors are rated for 5A current and operate across the same temperature range (-40°C to 85°C). The FCC17C37SM450 specifies a 200V voltage rating; the FCE17C37SM450 does not specify a voltage rating in the provided data. For applications requiring explicit voltage specification, the FCC17C37SM450 documentation should be consulted.

Q: What is the difference in dielectric material between these parts?

A: The FCC17C37SM450 uses standard thermoplastic dielectric material. The FCE17C37SM450 uses thermoplastic with glass reinforcement. Glass-filled thermoplastic provides improved mechanical strength and thermal stability while maintaining electrical performance.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates conformance to the Restriction of Hazardous Substances Directive, which restricts the use of specific hazardous materials in electrical and electronic equipment. The FCE17C37SM450 meets these requirements, making it suitable for applications and markets with RoHS mandates. The FCC17C37SM450 does not meet these requirements.

Q: Can I use the FCE17C37SM450 in existing designs that currently use the FCC17C37SM450?

A: Yes. The FCE17C37SM450 maintains full compatibility with all electrical and mechanical specifications of the FCC17C37SM450. No circuit redesign or mechanical modification is required.

Q: Are both connectors available in the same packaging?

A: Both connectors are supplied without specified packaging designation in the provided data. Contact the manufacturer for current packaging and availability information.

Q: What is the contact finish specification for both connectors?

A: Both connectors feature gold-plated contacts with a thickness of 15.0µin (0.38µm) applied over phosphor bronze contact material. This specification ensures consistent electrical performance and corrosion resistance.
