Substitute Part Grouping Explanation

Substitute parts for the 33UBARS1-04SW01 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Critical Parameters for Substitution:

• Connector Type: USB-A (USB TYPE-A)
• Number of Contacts: 4 positions
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Current Rating: 1.5A
• Voltage Rating: 30VAC
• Operating Temperature Range: -55°C ~ 85°C
• Contact Finish: Gold
• Shielding Configuration: Unshielded
• Material Flammability: UL94 V-0
• Regulatory Compliance: ROHS3 Compliant

The substitute part 33UBARS1-04SW11 matches all critical electrical and mechanical parameters. The primary difference is packaging configuration (Box versus standard packaging), which does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 33UBARS1-04SW01 and 33UBARS1-04SW11 are active products from Amphenol CONEC with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Inventory Availability: The 33UBARS1-04SW01 has 987 pieces in stock, while the 33UBARS1-04SW11 has 649 pieces in stock. Choose based on procurement timeline and quantity requirements.

Packaging Configuration: The 33UBARS1-04SW01 uses standard packaging, while the 33UBARS1-04SW11 uses Box packaging. Select based on your assembly process requirements and storage specifications.

Regulatory Compliance: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both meet UL94 V-0 flammability requirements and are suitable for applications requiring these certifications.

Functional Equivalence: The parts are functionally equivalent for all USB-A receptacle applications requiring 4-position surface mount, right-angle, horizontal mounting with 1.5A current capacity and -55°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 33UBARS1-04SW11 be used as a direct replacement for 33UBARS1-04SW01?

A: Yes. Both parts are functionally equivalent with identical electrical and mechanical specifications. The only difference is packaging configuration (Box versus standard). Direct substitution is valid for all applications where the original part is specified.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (USB-A receptacle), contact count (4 positions), mounting configuration (surface mount, right angle, horizontal), current rating (1.5A), voltage rating (30VAC), operating temperature range (-55°C to 85°C), contact finish (gold), shielding type (unshielded), and material flammability rating (UL94 V-0).

Q: Does packaging type affect electrical performance?

A: No. Packaging type (standard versus Box) does not affect electrical performance, mechanical fit, or functional compatibility. Packaging selection is based on assembly process requirements, storage conditions, and logistics preferences.

Q: Are both parts RoHS compliant?

A: Yes. Both 33UBARS1-04SW01 and 33UBARS1-04SW11 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the current rating for these connectors?

A: Both connectors have a current rating of 1.5A at 30VAC, suitable for standard USB-A applications within this power specification.

Q: What is the operating temperature range?

A: Both connectors operate across -55°C to 85°C, providing wide temperature range compatibility for industrial and commercial applications.

Q: Are these connectors shielded?

A: No. Both connectors are unshielded. If EMI shielding is required, alternative connector designs must be specified.

Q: What is the contact finish material?

A: Both connectors feature gold-plated contacts, providing corrosion resistance and reliable electrical connection performance.
