Amphenol CONEC 17-210021 USB-A Connector Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 17-210021 is an active USB-A (USB TYPE-A) USB 2.0 receptacle connector designed for panel mount applications. This 4-position connector features circular bayonet coupling, IP67 ingress protection, and shielded construction with gold-plated contacts. The connector is rated for 1.5A at 30V and operates across -40°C to 85°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), substitute parts are identified to provide alternative sourcing options for procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol CONEC 17-210021 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Connector Type & USB Specification: USB-A receptacle, USB 2.0 compliant
• Contact Configuration: 4-position connector
• Mounting Architecture: Panel mount with bulkhead front side nut
• Electrical Performance: 1.5A current rating, 30V voltage rating
• Environmental Protection: IP67 ingress protection rating
• Termination Method: PC board termination
• Material & Compliance: Copper alloy shell, UL94 V-0 flammability, ROHS3 compliance

The identified substitute part maintains all these parameters while introducing an additional potted feature for enhanced environmental sealing. This feature addition does not alter the core electrical or mechanical compatibility of the connector.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol CONEC 17-210021 and 17-210051 are active products with full ROHS3 compliance and REACH unaffected status, making them suitable for current and future production applications. The 17-210051 substitute part includes potted construction, which provides additional environmental sealing beyond the base circular bayonet coupling design. This enhancement does not compromise electrical or mechanical compatibility and may be selected when enhanced moisture or contaminant protection is required within the same operational envelope.

Selection between these parts should be based on inventory availability, lead time requirements, and specific application environmental demands. Both connectors maintain identical electrical performance, thermal operating range, and compliance certifications. The potted feature of the 17-210051 represents an engineering enhancement rather than a functional deviation.

Frequently Asked Questions (FAQ)

Q: Are the 17-210021 and 17-210051 electrically interchangeable?

A: Yes. Both connectors are USB 2.0 receptacles with identical 4-position contact configuration, 1.5A current rating, and 30V voltage rating. They share the same PC board termination method and gold-plated contact finish.

Q: What is the difference between the two parts?

A: The 17-210051 includes potted construction in addition to the circular bayonet coupling feature present in the 17-210021. This potting provides enhanced environmental sealing for moisture and contaminant ingress protection while maintaining all other electrical and mechanical specifications.

Q: Can I use the 17-210051 as a direct replacement for the 17-210021 in existing designs?

A: Yes. The 17-210051 maintains identical mounting geometry (panel mount with bulkhead front side nut), termination method (PC board), and electrical specifications. The potted feature is an enhancement that does not alter mechanical fit or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 17-210021 and 17-210051 are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Both operate across -40°C to 85°C and maintain IP67 ingress protection.

Q: What is the significance of the IP67 rating on these connectors?

A: IP67 rating indicates dust-tight and waterproof protection. These connectors are sealed against dust ingress and can withstand temporary immersion in water, making them suitable for harsh environmental applications.

Q: Are there any packaging or inventory considerations when selecting between these parts?

A: The 17-210021 has 1035 pieces in stock, while the 17-210051 has 701 pieces in stock. Selection may be influenced by immediate availability requirements and procurement lead times.

Q: What mounting feature do these connectors use?

A: Both connectors use bulkhead front side nut mounting, which secures the connector to a panel from the front with a threaded nut, providing robust mechanical retention for panel mount applications.
