Engineering Selection Recommendations

All identified substitute parts maintain full parametric equivalence to the TE Connectivity 1-1734085-3 across mandatory connector specifications. Selection among these alternatives is based on the following engineering criteria:

Regulatory Compliance: The main part carries RoHS Compliant status. All substitute parts are ROHS3 Compliant, which represents an updated compliance designation and is acceptable for applications requiring RoHS compliance. The TE Connectivity 1-1734775-1 maintains the same manufacturer lineage as the main part.

Inventory Availability: Substitute parts demonstrate varying stock levels. The Molex 0673298001 offers the highest inventory (15,880 pcs), followed by 0894858000 (18,422 pcs). The TE Connectivity 1-1734775-1 provides 4,968 pcs. Selection based on inventory availability supports supply chain continuity.

Manufacturer Diversity: TE Connectivity and Molex are both established connector manufacturers. The TE Connectivity 1-1734775-1 provides same-manufacturer substitution. Molex alternatives (0482040001, 0673298 series, 0894858 series) offer cross-manufacturer equivalence.

Product Status: All parts are listed as Active, confirming ongoing production and support.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1734775-1 be used as a direct replacement for 1-1734085-3?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical parametric specifications for connector type, USB 2.0 compliance, 4-position receptacle configuration, through-hole right-angle mounting, board lock feature, shielding, gold contact finish, UL94 V-0 flammability rating, and MSL 1 rating. The primary difference is packaging format (Tray for 1-1734775-1 versus unspecified for 1-1734085-3) and shell material composition (Phosphor Bronze versus Brass/Steel SPCC).

Q: What is the difference between the Molex 0673298 series parts (0673298000, 0673298001, 0673298020, 0673298021)?

A: All four parts belong to the Molex 67329 series and maintain identical parametric specifications for USB-A USB 2.0 receptacle connectors with 4 positions, through-hole right-angle mounting, board lock, shielding, and gold contacts. Differences exist only in inventory levels and part number suffixes, which typically indicate manufacturing lot or packaging variations. All are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between the Molex 0894858 series parts (0894858000, 0894858001, 0894858002, 0894858003)?

A: All four parts belong to the Molex 89485 series and maintain identical parametric specifications for USB-A USB 2.0 receptacle connectors with 4 positions, through-hole right-angle mounting, board lock, shielding, and gold contacts. Differences exist only in inventory levels and part number suffixes. All are ROHS3 compliant, carry MSL 1 rating, and specify operating temperature range of 0°C to 50°C with 750VAC voltage rating and 1A per contact current rating.

Q: Are there operating temperature or current rating differences between substitute parts?

A: Yes. The main part 1-1734085-3 does not specify operating temperature or current rating parameters. The Molex 0482040001 specifies -55°C to 85°C operating temperature with 1.5A current rating and 30VAC voltage rating. The Molex 0673298 series specifies 1A current rating without temperature range specification. The Molex 0894858 series specifies 0°C to 50°C operating temperature with 1A per contact current rating and 750VAC voltage rating. These differences do not affect parametric substitution eligibility but should be evaluated for specific application thermal and electrical requirements.

Q: Can I substitute a Molex part for the TE Connectivity main part?

A: Yes. All Molex substitute parts (0482040001, 0673298000, 0673298001, 0673298020, 0673298021, 0894858000, 0894858001, 0894858002, 0894858003) maintain identical parametric specifications across all mandatory connector parameters: USB-A USB 2.0 receptacle, 4 positions, through-hole right-angle mounting, vertical flag mounting feature, solder termination, board lock, shielding, gold contact finish, UL94 V-0 flammability rating, black insulation, and MSL 1 rating. Cross-manufacturer substitution is supported by parametric equivalence.

Q: What packaging formats are available?

A: The main part 1-1734085-3 does not specify packaging format. The TE Connectivity 1-1734775-1 is packaged in Tray format. All Molex substitute parts (0482040001, 0673298 series, 0894858 series) are packaged in Tray format. Tray packaging is standard for high-volume connector distribution and supports automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 1-1734085-3 is RoHS Compliant. All substitute parts carry ROHS3 Compliant designation, which represents the current RoHS compliance standard and is acceptable for applications requiring RoHS compliance.
