Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part number 794637-8 and the equivalent part 3-794637-8 is determined by strict alignment of electrical and mechanical parameters. Both parts share identical specifications across all critical substitution criteria: connector type (Header), contact type (Male Pin), position count (8), row configuration (2), mating pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), mounting method (Surface Mount), termination type (Solder), shrouding design (Shrouded - 4 Wall), fastening mechanism (Locking Ramp), voltage rating (250V), operating temperature range (-40°C ~ 105°C), and flammability classification (UL94 V-0). The primary distinction between these parts lies in packaging format and compliance status. Part 794637-8 is supplied in standard packaging with RoHS non-compliant status and REACH Affected classification. Part 3-794637-8 is supplied in Cut Tape (CT) and Digi-Reel® packaging with ROHS3 Compliant status and REACH Unaffected classification. A secondary difference exists in the contact finish post specification: 794637-8 uses Tin-Lead finish while 3-794637-8 uses Tin finish. Both finishes maintain the same thickness specification of 100.0µin (2.54µm).

Parameter Comparison

Engineering Selection Recommendations

Both 794637-8 and 3-794637-8 are Active product status connectors from TE Connectivity AMP Connectors within the Micro MATE-N-LOK series. Selection between these parts is determined by compliance and packaging requirements rather than electrical or mechanical performance differences.

Part 794637-8 is appropriate for applications where RoHS non-compliance is acceptable and REACH Affected status does not present regulatory constraints. This part is supplied in standard packaging format.

Part 3-794637-8 is appropriate for applications requiring ROHS3 Compliance and REACH Unaffected status. This part is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, which are suitable for automated assembly processes and high-volume production environments. The contact finish post specification differs between parts: 794637-8 uses Tin-Lead while 3-794637-8 uses Tin. Both finishes maintain identical thickness specifications and are suitable for solder termination applications.

Selection of 3-794637-8 is indicated for new designs, regulated industries, and applications subject to environmental compliance mandates. Selection of 794637-8 is indicated for legacy designs, non-regulated applications, and situations where existing inventory or procurement channels are established.

Frequently Asked Questions (FAQ)

Q: Are 794637-8 and 3-794637-8 electrically and mechanically interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, contact configuration, pitch, row spacing, mounting method, termination type, shrouding design, fastening mechanism, voltage rating, and operating temperature range. Substitution is direct for applications where compliance status and packaging format are not constraints.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format and compliance status. Part 794637-8 is supplied in standard packaging with RoHS non-compliant and REACH Affected status. Part 3-794637-8 is supplied in Cut Tape (CT) and Digi-Reel® packaging with ROHS3 Compliant and REACH Unaffected status. A secondary difference exists in contact finish post material: 794637-8 uses Tin-Lead while 3-794637-8 uses Tin.

Q: Does the contact finish post difference between Tin-Lead and Tin affect solder joint reliability?

A: Both contact finish post specifications maintain identical thickness of 100.0µin (2.54µm) and are suitable for solder termination. The selection between Tin-Lead and Tin finishes is determined by compliance requirements and manufacturing process compatibility rather than solder joint performance.

Q: Which part should be selected for new product designs?

A: Part 3-794637-8 is appropriate for new product designs due to ROHS3 Compliance and REACH Unaffected status, which align with current environmental and regulatory standards. The Cut Tape (CT) and Digi-Reel® packaging also supports automated assembly processes typical in modern manufacturing environments.

Q: Can 794637-8 be used in applications requiring RoHS compliance?

A: No. Part 794637-8 is RoHS non-compliant. Applications requiring RoHS compliance must use part 3-794637-8, which carries ROHS3 Compliant status.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 105°C and carry the same UL94 V-0 flammability rating.

Q: What packaging formats are available for each part?

A: Part 794637-8 is supplied in standard packaging. Part 3-794637-8 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, which are optimized for automated pick-and-place assembly and tape-and-reel handling systems.

Q: Is the Moisture Sensitivity Level (MSL) the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.
