Substitute Part Grouping Explanation

Substitution between 794620-2 and 3-794620-2 is based on functional and mechanical equivalence within the Micro MATE-N-LOK series. Both parts maintain identical specifications across all critical parameters that define connector compatibility:

Key Parameters Determining Substitution:

• Connector Type, Contact Type, and Position Configuration (Header, Male Pin, 2-position, 2-row)
• Mechanical Mounting and Orientation (Through Hole, Right Angle)
• Shrouding Design and Fastening Method (Shrouded 4-Wall, Locking Ramp)
• Electrical Performance (250V rating, temperature range -40°C to 105°C)
• Contact Materials and Finishes (Brass with Gold mating surface)
• Insulation Specifications (Polyamide/Nylon, UL94 V-0)

The primary distinction between these parts is packaging format and compliance status. The 794620-2 is supplied in standard packaging, while 3-794620-2 is supplied in Tray packaging. Additionally, 3-794620-2 carries RoHS Compliant status, whereas 794620-2 is RoHS non-compliant. The contact finish on the post differs slightly: 794620-2 uses Tin-Lead while 3-794620-2 uses Tin.

Parameter Comparison

Engineering Selection Recommendations

Both 794620-2 and 3-794620-2 are Active products from TE Connectivity and are functionally equivalent for connector interface applications. Selection between these parts should be based on the following criteria:

794620-2 is appropriate for applications where:

• Standard packaging is acceptable for assembly processes
• RoHS compliance is not a design requirement
• Tin-Lead post finish meets soldering specifications

3-794620-2 is appropriate for applications where:

• Tray packaging is required for automated handling or bulk assembly
• RoHS Compliance is mandated by design specifications or regulatory requirements
• Tin post finish is compatible with soldering processes

Both parts carry identical electrical ratings (250V), thermal specifications (-40°C to 105°C), and mechanical configurations. The contact finish difference (Tin-Lead versus Tin) represents a material composition change in the post termination, with both finishes providing equivalent solder joint performance in standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Are 794620-2 and 3-794620-2 mechanically interchangeable?

A: Yes. Both parts are identical in all mechanical dimensions, mounting configuration, and connector interface specifications. They share the same 2-position, 2-row layout with 0.118" (3.00mm) row spacing, through-hole right-angle mounting, and shrouded 4-wall construction.

Q: What is the difference between Tin-Lead and Tin post finishes?

A: The 794620-2 uses Tin-Lead post finish while 3-794620-2 uses Tin post finish. Both finishes are suitable for solder termination in PCB assembly. The Tin finish in 3-794620-2 aligns with RoHS compliance requirements that restrict lead content.

Q: Why does 3-794620-2 have RoHS Compliant status while 794620-2 does not?

A: The RoHS compliance difference is directly related to the post finish material. The Tin-Lead finish in 794620-2 contains lead, which is restricted under RoHS regulations. The Tin finish in 3-794620-2 eliminates lead content, achieving RoHS Compliant status.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The difference between standard packaging (794620-2) and Tray packaging (3-794620-2) is purely logistical. Both packaging formats contain identical connector components with no impact on electrical ratings, thermal performance, or mechanical fit.

Q: Can I substitute 3-794620-2 for 794620-2 in an existing design?

A: Yes, provided the design does not specifically require Tin-Lead post finish or non-compliant RoHS status. The 3-794620-2 offers improved compliance characteristics while maintaining full functional equivalence.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. The connector specifications do not define a fixed amperage rating; instead, current capacity is determined by the wire gauge of the connected conductors and applicable industry standards for that gauge.

Q: Are both parts suitable for the full -40°C to 105°C temperature range?

A: Yes. Both 794620-2 and 3-794620-2 maintain identical operating temperature specifications of -40°C to 105°C and carry the same UL94 V-0 flammability rating.

Q: What is the voltage rating for these connectors?

A: Both parts are rated for 250V maximum voltage. This rating applies to the insulation system and contact configuration across the 2-position, 2-row interface.
