Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility is determined by matching the following critical parameters across connector housings within the Solaris series:

• Connector type (Plug housing)
• Contact type (Female Socket)
• Number of positions (3)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Insulation material (Polyetherimide PEI)
• Operating temperature range (-65°C to 150°C)
• Environmental sealing (IP67)
• Regulatory compliance (RoHS)

The SQR320150 matches all critical parameters with the SQR320110-3, making it a direct functional equivalent for applications requiring 3-position rectangular connector housings with the specified electrical and mechanical characteristics.

Both parts maintain RoHS compliance and equivalent operating characteristics across temperature and environmental ratings. Selection of the SQR320150 is supported by full parametric equivalence and superior supply chain status.

Frequently Asked Questions (FAQ)

Q: Are SQR320110-3 and SQR320150 interchangeable?

A: Yes. Both components are 3-position rectangular connector housings with identical connector type, contact configuration, termination method, and operating specifications. They share the same base product number (SQR32) within the Solaris series.

Q: What is the primary difference between these parts?

A: The SQR320110-3 is obsolete, while the SQR320150 maintains active product status. All electrical and mechanical parameters are equivalent.

Q: Can the SQR320150 replace SQR320110-3 in existing designs?

A: The SQR320150 can be used in any application originally specified for the SQR320110-3 without design modification, as all critical parameters are equivalent.

Q: Are there any compatibility concerns with contact pins?

A: Both housings accept crimp-terminated contacts designed for the Solaris series 3-position configuration. Contact selection must match the specified wire gauge (20 AWG) and termination requirements.

Q: What certifications apply to the substitute part?

A: The SQR320150 is RoHS compliant and carries the same ECCN (EAR99) and HTSUS (8538.90.6000) classifications as the original part.
