Parameter Comparison

Engineering Selection Recommendations

The 1-794487-1 serves as the direct active substitute for the obsolete 794487-1 rectangular connector header. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, pitch, mounting method, and environmental ratings.

The primary distinction between these parts relates to product lifecycle status and regulatory compliance. The 794487-1 is classified as obsolete with RoHS non-compliant status and vendor-undefined REACH compliance. The 1-794487-1 is an active product with RoHS compliant certification and REACH unaffected status, indicating current manufacturing support and alignment with contemporary environmental regulations.

Contact finish specifications differ between the two parts. The 794487-1 employs tin-lead plating on both mating and post contacts, while the 1-794487-1 utilizes tin plating. Both finishes maintain the same thickness specification of 118.1µin (3.00µm) and provide equivalent electrical performance and reliability characteristics within the specified operating parameters.

For new designs and ongoing procurement requirements, the 1-794487-1 is the appropriate selection due to active product status, regulatory compliance certifications, and continued manufacturing availability. Existing designs utilizing the 794487-1 can transition to the 1-794487-1 without modification, as all functional and dimensional specifications remain identical.

Frequently Asked Questions (FAQ)

Q: Are the 794487-1 and 1-794487-1 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 10-position configuration, 2-row arrangement, 0.165" (4.20mm) pitch, through-hole mounting, shrouded 4-wall construction, and solder termination. They are direct mechanical replacements without requiring PCB redesign or connector cavity modification.

Q: What is the difference in contact finish between these two parts?

A: The 794487-1 features tin-lead plating on both mating and post contacts. The 1-794487-1 uses tin plating on both contact surfaces. Both finishes maintain identical thickness at 118.1µin (3.00µm) and deliver equivalent electrical conductivity and corrosion resistance within the specified operating temperature range of -55°C to 105°C.

Q: Why is the 794487-1 listed as obsolete?

A: The 794487-1 has reached end-of-life status in the manufacturer's product portfolio. The 1-794487-1 represents the current active equivalent, offering the same functional performance with updated compliance certifications and ongoing manufacturing support.

Q: Does the 1-794487-1 meet RoHS requirements?

A: Yes. The 1-794487-1 is RoHS compliant, whereas the 794487-1 is RoHS non-compliant. This compliance difference reflects the transition from tin-lead to tin contact finishes and updated material certifications in the active product line.

Q: Can I use the 1-794487-1 as a direct replacement in existing assemblies designed for the 794487-1?

A: Yes. The 1-794487-1 is a direct functional replacement. All electrical, mechanical, and dimensional specifications are identical. The connector will mate with existing mating connectors and perform identically within the specified operating parameters.

Q: What is the REACH status difference between these parts?

A: The 794487-1 lists vendor-undefined REACH status, indicating incomplete compliance documentation. The 1-794487-1 specifies REACH unaffected status, confirming that the connector composition does not contain substances of very high concern (SVHC) subject to REACH authorization requirements.

Q: Are both connectors rated for 600VAC operation?

A: Yes. Both the 794487-1 and 1-794487-1 carry identical 600VAC voltage ratings and UL94 V-0 material flammability certification, ensuring equivalent electrical safety performance in high-voltage applications.

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