Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SQR320111-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (3)
• Wire gauge rating (20 AWG)
• Number of rows (1)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line)
• Fastening type (Latch Lock)
• Base product number (SQR32)
• Series (Solaris)

Environmental & Compliance Parameters:

• IP67 protection rating
• RoHS compliance

The substitute part SQR320151 maintains identical specifications across all these parameters while offering active product status and improved regulatory documentation.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SQR320151

The SQR320151 is the direct functional equivalent of the obsolete SQR320111-3. Both connectors share identical electrical and mechanical specifications within the Amphenol PCD Solaris series. The SQR320151 offers the following advantages:

• Active product status with ongoing manufacturer support
• Full RoHS compliance with documented ECCN classification (EAR99)
• Complete regulatory documentation (HTSUS code 8536.69.8000)
• Moisture sensitivity level specification (MSL 1 - Unlimited)
• Current inventory availability (678 pcs in stock)

For applications currently using SQR320111-3, direct substitution with SQR320151 is supported without design modification. The identical base product number (SQR32), connector configuration, and environmental ratings ensure mechanical and electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can SQR320151 directly replace SQR320111-3 in existing assemblies?

A: Yes. Both connectors are identical in electrical and mechanical specifications. The SQR320151 maintains the same 3-position configuration, 20 AWG wire rating, IP67 protection, latch lock fastening, and free-hanging in-line mounting. No design changes are required.

Q: What is the difference between SQR320111-3 and SQR320151?

A: The primary difference is product status. SQR320111-3 is obsolete, while SQR320151 is active. SQR320151 includes complete regulatory documentation (ECCN and HTSUS codes) and specified moisture sensitivity level. All functional parameters are identical.

Q: Are there any compatibility concerns when switching from SQR320111-3 to SQR320151?

A: No compatibility concerns exist. Both parts share the same base product number (SQR32), series designation (Solaris), and all critical electrical and mechanical parameters. Mating connectors and cable assemblies designed for SQR320111-3 are fully compatible with SQR320151.

Q: Why is SQR320111-3 classified as obsolete?

A: Obsolescence classification is determined by the manufacturer. SQR320151 represents the current active equivalent within the Solaris series and should be used for new designs and ongoing production.

Q: What is the inventory status for these parts?

A: SQR320111-3 has 679 pcs in stock (obsolete status). SQR320151 has 678 pcs in stock (active status). For new applications, SQR320151 is the recommended selection.

Q: Are both parts RoHS compliant?

A: Yes. Both SQR320111-3 and SQR320151 are RoHS compliant. SQR320151 includes additional regulatory documentation with ECCN classification (EAR99) and HTSUS code (8536.69.8000).
