Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-1734028-3 are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Compatibility:

• USB 2.0 specification compliance
• 4-position contact configuration
• 1.5A current rating
• 30VDC voltage rating
• 1500 mating cycle rating

Mechanical Compatibility:

• USB-A plug connector type
• Surface mount and through-hole mounting capability
• Right-angle horizontal orientation
• Shielded construction with steel shielding material
• Gold contact finish

Compliance & Environmental:

• UL94 V-0 flammability rating
• ROHS3 compliance
• MSL 1 moisture sensitivity level
• Operating temperature range 0°C to 50°C

The identified substitute part maintains all these parameters while differing only in packaging format (Tape & Reel versus Cut Tape) and insulation color, neither of which affects functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1734028-1 is a direct functional equivalent to the 1-1734028-3 for all circuit design and application requirements. Both parts are active products from TE Connectivity AMP Connectors with identical electrical ratings, mechanical specifications, and compliance certifications.

Selection Basis:

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for consumer and industrial applications. The identical current rating (1.5A), voltage rating (30VDC), and mating cycle specification (1500) ensure equivalent performance in USB 2.0 data and power delivery applications.

The mechanical compatibility is complete: both connectors feature the same USB-A plug configuration, surface mount and through-hole mounting capability, right-angle horizontal orientation, shielded construction with steel shielding, and gold-plated contacts. These specifications ensure identical PCB footprint compatibility and connector interface performance.

The only differences between the parts are packaging format (Tape & Reel versus Cut Tape) and insulation color (Black versus Natural). These differences do not affect functional performance, electrical characteristics, or mechanical compatibility. Selection between these parts should be based on procurement requirements, inventory management, and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1-1734028-1 be used as a direct replacement for the 1-1734028-3 in production designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same USB 2.0 specification, 4-position configuration, 1.5A current rating, 30VDC voltage rating, and 1500 mating cycle specification. Both feature identical shielding, contact finish, and flammability compliance. The parts are functionally interchangeable for all circuit applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs. Both packaging formats contain the same component with identical electrical and mechanical specifications.

Q: Does the insulation color difference between Black and Natural affect connector performance?

A: No. Insulation color is a cosmetic specification that does not affect electrical performance, mechanical compatibility, or signal integrity. Both colors provide equivalent insulation properties and do not impact circuit functionality.

Q: Are both parts suitable for USB 2.0 applications?

A: Yes. Both the 1-1734028-3 and 1-1734028-1 are certified for USB 2.0 specification compliance. They support the same data rates and power delivery requirements for USB 2.0 devices and applications.

Q: What is the operating temperature range for these connectors?

A: Both parts operate within the range of 0°C to 50°C. This temperature specification applies to both the 1-1734028-3 and 1-1734028-1 and should be considered when selecting connectors for temperature-sensitive applications.

Q: Are these connectors RoHS compliant?

A: Yes. Both the 1-1734028-3 and 1-1734028-1 are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions in electronic components.

Q: What is the current rating for these USB-A connectors?

A: Both connectors are rated for 1.5A continuous current at 30VDC. This rating applies to both the main part and substitute part and determines the maximum power delivery capability in USB 2.0 applications.

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

A: Both the 1-1734028-3 and 1-1734028-1 are rated for 1500 mating cycles, indicating the expected connector lifespan under normal insertion and removal conditions.
