Substitute parts differ only in packaging format and product status. These differences do not affect electrical or mechanical compatibility in the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1-1734028-1

The 1-1734028-1 is the recommended substitute for the obsolete 1-1734028-4. This part maintains complete electrical and mechanical equivalence while offering the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance provides enhanced regulatory alignment
• Highest inventory availability (6534 units) supports production continuity
• Cut Tape (CT) packaging format accommodates both manual and automated assembly processes

Secondary Substitute: 1-1734028-3

The 1-1734028-3 provides an alternative substitute with identical electrical and mechanical specifications. This part is suitable when Tape & Reel (TR) packaging is required for high-volume automated assembly operations.

• Active product status ensures ongoing supply chain support
• ROHS3 compliance meets current regulatory requirements
• Tape & Reel packaging optimized for pick-and-place equipment

Packaging Considerations:

Selection between 1-1734028-1 and 1-1734028-3 depends on assembly methodology and production volume requirements. Both parts are electrically and mechanically interchangeable with the 1-1734028-4.

Compliance Status:

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. RoHS compliance is maintained across all substitutes, with 1-1734028-1 and 1-1734028-3 offering ROHS3 certification for enhanced regulatory coverage.

Frequently Asked Questions (FAQ)

Q: Can 1-1734028-1 and 1-1734028-3 be used interchangeably with 1-1734028-4?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the 1-1734028-4. All three parts share identical connector type, contact count, USB 2.0 specification, current rating, voltage rating, mounting configuration, termination method, and environmental specifications. Substitution is direct without circuit modification or design changes.

Q: What is the difference between the packaging formats?

A: The 1-1734028-4 is supplied in bulk packaging. The 1-1734028-1 is supplied in Cut Tape (CT) format, suitable for manual assembly and small-to-medium production runs. The 1-1734028-3 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly equipment in high-volume manufacturing. The connector itself is identical across all packaging formats.

Q: Why is the 1-1734028-4 classified as obsolete?

A: The 1-1734028-4 has been superseded by active product variants. The substitute parts 1-1734028-1 and 1-1734028-3 provide equivalent functionality with improved product status and regulatory compliance. Existing inventory of the 1-1734028-4 remains available, but new designs should specify the active substitutes.

Q: Are there any differences in the insulation color between substitute parts?

A: The 1-1734028-4 and 1-1734028-3 feature black insulation color. The 1-1734028-1 features natural insulation color. This cosmetic difference does not affect electrical performance or mechanical compatibility. Selection based on insulation color preference is application-dependent.

Q: Do all substitute parts meet current RoHS requirements?

A: Yes. The 1-1734028-4 is RoHS Compliant. The substitute parts 1-1734028-1 and 1-1734028-3 are ROHS3 Compliant, providing enhanced regulatory alignment with current RoHS 3 directives. All parts are suitable for applications requiring RoHS compliance.

Q: What is the moisture sensitivity level for these connectors?

A: All parts, including the main part and substitutes, have a Moisture Sensitivity Level (MSL) of 1 (Unlimited). This classification indicates no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can these USB 2.0 connectors be used in USB 3.0 applications?

A: These connectors are specified for USB 2.0 applications. Use in USB 3.0 systems requires verification against the specific application requirements and system design specifications.

Q: What is the maximum current these connectors can handle?

A: All parts have a current rating of 1.5A at the specified operating temperature range of 0°C to 50°C.

Q: How many mating cycles are these connectors rated for?

A: All parts are rated for 1500 mating cycles, indicating the expected number of connect/disconnect operations before performance degradation.
