SD-30SN Equivalent & Substitute Parts

Part Overview

The SD-30SN is a 3-position circular connector receptacle manufactured by CUI Devices, featuring female sockets with solder eyelet termination and DIN 180-degree shell configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The SD-30SN serves applications requiring shielded circular connectors with panel-mount flange configuration and push-pull fastening. Due to its obsolete status, sourcing equivalent parts from active product lines ensures supply chain continuity and long-term availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD-30SN are identified based on strict alignment with the following critical parameters:

• Connector type: Receptacle with female sockets
• Position count: 3-position configuration
• Shell size: DIN 180-degree standard
• Mounting: Panel mount with flange feature
• Termination: Solder eyelet(s)
• Fastening: Push-pull mechanism
• Shielding: Shielded construction
• Regulatory compliance: ROHS3 compliant

The 57GB3FX from Switchcraft Inc. meets all mandatory substitution criteria. This part maintains functional equivalence across mechanical interface, electrical termination method, and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The 57GB3FX represents a direct functional equivalent for the obsolete SD-30SN. Both components satisfy identical mechanical and electrical interface requirements within the specified operating parameters.

Selection of the 57GB3FX is supported by:

• Active product status, ensuring ongoing availability and supply chain stability
• Full ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment
• Identical mechanical interface: DIN 180-degree shell, 3-position, panel-mount flange configuration
• Equivalent termination method: solder eyelet(s) for direct PCB integration
• Matching shielding architecture for electromagnetic compatibility

The substitute part accommodates existing mechanical mounting and electrical connection schemes without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 57GB3FX directly replace the SD-30SN in existing assemblies?

A: Yes. Both components share identical mechanical interfaces (DIN 180-degree shell, 3-position, panel-mount flange) and termination methods (solder eyelet). No design changes are required for mechanical or electrical integration.

Q: What are the key compatibility criteria for this substitution?

A: Compatibility is determined by: connector type (receptacle, female sockets), position count (3), shell size standard (DIN 180-degree), mounting configuration (panel mount with flange), termination method (solder eyelet), and fastening mechanism (push-pull). The 57GB3FX matches all these parameters.

Q: Are there regulatory compliance differences between these parts?

A: No. Both the SD-30SN and 57GB3FX are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes.

Q: What is the packaging difference?

A: The SD-30SN is supplied in standard packaging, while the 57GB3FX is supplied in bulk packaging. This affects order quantities and handling but does not impact component functionality or performance.

Q: Why is the SD-30SN classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The 57GB3FX, with active product status, provides continuity for applications requiring this connector type.
