Switchcraft 57GA3F Circular Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 57GA3F is a 3-position circular connector receptacle with female sockets designed for solder termination. This DIN 180-degree connector serves as a panel-mount component with push-twist fastening and shielded construction. The part is currently in active production with 989 pieces available in new original stock condition. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The 57HB3FX qualifies as a direct substitute for the 57GA3F based on alignment of critical substitution parameters. Both connectors share identical specifications across the following key criteria:

• Connector type: Receptacle with female sockets
• Position count: 3 positions
• Shell size and insert standard: DIN 180-degree configuration
• Mounting configuration: Panel mount with flange
• Termination method: Solder eyelet(s)
• Fastening mechanism: Push-twist
• Shielding: Shielded construction
• Primary and shell materials: Metal and steel
• Contact finish: Tin plating on mating surfaces
• Grounding feature: Present
• Regulatory compliance: ROHS3 compliant

The 57HB3FX is manufactured by the same supplier (Switchcraft Inc.) and maintains active product status with 831 pieces in new original stock. Substitution is valid when these mechanical and electrical parameters are the controlling factors for component selection in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the 57GA3F and 57HB3FX maintain active product status from Switchcraft Inc., ensuring continued availability and manufacturing support. The 57HB3FX carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications. Selection between these parts should be based on inventory availability and application-specific mechanical constraints such as panel mounting geometry and flange requirements. The 57HB3FX's documented flange mounting feature provides additional mechanical stability in panel-mount installations. Both connectors are suitable for solder termination processes and support identical push-twist fastening mechanisms.

Frequently Asked Questions (FAQ)

Q: Can the 57HB3FX replace the 57GA3F in existing designs?

A: Yes. Both connectors share identical specifications for connector type, position count, shell size (DIN 180-degree), mounting type, termination method, and fastening mechanism. Substitution is valid when these parameters control the component selection criteria.

Q: What are the key compatibility factors between these connectors?

A: Critical compatibility factors include the 3-position configuration, DIN 180-degree shell size standard, panel-mount orientation, solder eyelet termination, and push-twist fastening. Both connectors maintain these specifications identically.

Q: Does the 57HB3FX include a flange mounting feature?

A: Yes. The 57HB3FX is specified with flange mounting, providing additional mechanical retention in panel-mount applications. Verify that the application design accommodates flange geometry if transitioning from the 57GA3F.

Q: Are both connectors RoHS compliant?

A: The 57HB3FX is certified ROHS3 compliant. Compliance status for the 57GA3F is not specified in the available documentation. Confirm RoHS requirements for your application before final part selection.

Q: What is the packaging difference between these parts?

A: The 57GA3F packaging specification is not provided. The 57HB3FX is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both connectors shielded?

A: The 57HB3FX is specified as shielded construction. Shielding specification for the 57GA3F is not documented. If EMI shielding is a design requirement, the 57HB3FX provides this feature.
