Engineering Selection Recommendations

Primary Substitute: 1-794073-0

The TE Connectivity 1-794073-0 is the manufacturer-recommended substitute for the 794073-1. This part maintains full mechanical and electrical compatibility while offering significant advantages in procurement and regulatory compliance.

Product Status Consideration: The 794073-1 is classified as Last Time Buy, indicating end-of-life status with limited availability. The 1-794073-0 maintains Active product status with confirmed inventory of 3,136 pieces, ensuring reliable procurement for current and future applications.

Regulatory Compliance: The 1-794073-0 achieves ROHS3 compliance and REACH Unaffected status, whereas the 794073-1 is RoHS non-compliant and REACH Affected. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the 1-794073-0 is the appropriate selection.

Contact Finish Specification: The primary technical distinction is the contact finish. The 794073-1 specifies tin-lead finish, while the 1-794073-0 specifies tin finish. Both finishes provide equivalent electrical performance and solder compatibility for through-hole applications. The tin finish of the 1-794073-0 aligns with modern manufacturing standards and RoHS requirements.

Functional Equivalence: Both connectors share identical mechanical dimensions, pitch specifications, voltage ratings, temperature operating range, and flammability ratings. Direct substitution is supported without circuit design modification or PCB layout revision.

Frequently Asked Questions (FAQ)

Q: Can the 1-794073-0 be used as a direct replacement for the 794073-1 without PCB modification?

A: Yes. The 1-794073-0 maintains identical mechanical dimensions, pitch spacing, mounting hole patterns, and electrical ratings. Direct substitution on existing PCB designs is supported without layout or design changes.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both tin-lead and tin finishes provide equivalent electrical conductivity and solder wettability for through-hole solder termination. The tin finish of the 1-794073-0 reflects current manufacturing standards and RoHS compliance requirements. No functional difference exists for standard applications.

Q: Why is the 794073-1 designated as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production of this part number. Existing inventory is available for a limited period. The 1-794073-0 is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: Are there any applications where the 794073-1 must be used instead of the 1-794073-0?

A: No. The 1-794073-0 is functionally and mechanically equivalent. Applications currently using the 794073-1 can transition to the 1-794073-0 without performance impact. The 1-794073-0 is preferred due to active product status and improved regulatory compliance.

Q: What is the inventory status for each part?

A: The 794073-1 has 2,450 pieces in stock with Last Time Buy status. The 1-794073-0 has 3,136 pieces in stock with Active product status, providing greater availability and long-term procurement security.

Q: Do both parts meet the same electrical and temperature specifications?

A: Yes. Both the 794073-1 and 1-794073-0 are rated for 600VAC operation and function across the -20°C to 85°C temperature range. Both achieve UL94 V-0 flammability rating. Electrical performance is identical.

Q: Is the 1-794073-0 suitable for applications requiring RoHS compliance?

A: Yes. The 1-794073-0 is ROHS3 compliant and REACH Unaffected, making it suitable for applications subject to environmental regulations. The 794073-1 does not meet these compliance requirements.
