Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-794636-6 is a direct functional equivalent to the obsolete 1-794636-6 across all critical electrical and mechanical parameters. The primary differences are:

Product Status: The 4-794636-6 is classified as Active, ensuring ongoing availability and manufacturing support, whereas the 1-794636-6 is Obsolete.

Compliance Status: The 4-794636-6 is RoHS Compliant, meeting current regulatory requirements for electronic components. The 1-794636-6 has Not Applicable RoHS status, reflecting its obsolete classification.

Contact Finish Composition: The 1-794636-6 features Tin-Lead contact finish on both mating and post surfaces. The 4-794636-6 features Tin contact finish. Both maintain identical finish thickness of 100.0µin (2.54µm). This difference reflects the transition from lead-containing to lead-free finishes in modern manufacturing.

Packaging Format: The 1-794636-6 is supplied in bulk packaging, while the 4-794636-6 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

All other parameters, including connector geometry, electrical ratings, temperature range, flammability rating, and moisture sensitivity, are identical between the two parts. The 4-794636-6 is suitable for direct substitution in new designs and for replacement of obsolete 1-794636-6 components.

Frequently Asked Questions (FAQ)

Q: Can the 4-794636-6 be used as a direct replacement for the 1-794636-6 in existing applications?

A: Yes. The 4-794636-6 maintains identical electrical and mechanical specifications across all critical parameters, including voltage rating (250V), operating temperature range (-40°C ~ 105°C), connector geometry (16-position, 2-row, 0.118" pitch), mounting type (Surface Mount), and shrouding configuration (Shrouded - 4 Wall). The parts are functionally equivalent for board-to-cable/wire applications.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The 1-794636-6 uses Tin-Lead finish, while the 4-794636-6 uses Tin finish. Both finishes provide equivalent electrical conductivity and corrosion resistance at the specified thickness of 100.0µin (2.54µm). The Tin finish in the 4-794636-6 reflects compliance with lead-free manufacturing standards and RoHS regulations. Both finishes are suitable for solder termination applications.

Q: Does the packaging difference between bulk and Tape & Reel affect component compatibility?

A: No. Packaging format (bulk versus Tape & Reel) affects only the supply and handling method, not the electrical or mechanical performance of the connector itself. The 4-794636-6 in Tape & Reel format is optimized for automated assembly processes, while the 1-794636-6 in bulk format was suited for manual or legacy assembly methods. The connector specifications remain identical.

Q: Why is the 1-794636-6 classified as Obsolete?

A: The Obsolete classification indicates that the 1-794636-6 is no longer in active production. The 4-794636-6 represents the current production equivalent, incorporating modern manufacturing standards including RoHS compliance and lead-free contact finishes. For new designs and ongoing production, the 4-794636-6 is the recommended part.

Q: Are there any temperature or voltage limitations when substituting the 4-794636-6 for the 1-794636-6?

A: No. Both parts share identical voltage rating (250V) and operating temperature range (-40°C ~ 105°C). The 4-794636-6 is fully qualified for all applications within these specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the 1-794636-6 and 4-794636-6 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage or handling.

Q: Is the 4-794636-6 suitable for high-reliability applications?

A: Both parts meet UL94 V-0 material flammability rating and are designed for general-purpose applications. The 4-794636-6, being in active production with RoHS compliance, is suitable for applications requiring current regulatory compliance and ongoing component availability.
