Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SQR320211-3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with male pin contacts
• Position Count & Row Configuration: 3-position, single-row arrangement
• Wire Gauge Compatibility: 20 AWG discrete wire termination
• Mechanical Interface: Free hanging in-line mounting with latch lock fastening
• Environmental Rating: IP67 protection classification
• Series Compatibility: Solaris series base product (SQR32)
• Regulatory Compliance: RoHS compliant status

The substitute part SQR320211-3 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison
