TE Connectivity 794632-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794632-2 is a Micro MATE-N-LOK rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This shrouded 2-position connector features male pin contacts with gold-plated mating surfaces and tin-lead post finishes, rated for 250V operation across an extended temperature range of -40°C to 105°C. The connector is classified as Active product status and serves general-purpose applications requiring reliable press-fit or solder termination.

Substitute parts are identified to address packaging variations, compliance requirements, and inventory availability while maintaining electrical and mechanical compatibility within the Micro MATE-N-LOK series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 794632-2 is determined by strict alignment with critical electrical and mechanical parameters. All substitute parts must maintain identical specifications across the following criteria:

Critical Substitution Parameters:

• Connector series designation (Micro MATE-N-LOK)
• Contact configuration (2 positions, 2 rows, male pin type)
• Geometric spacing (0.118" row spacing)
• Mounting methodology (through-hole)
• Electrical ratings (250V, -40°C to 105°C operating range)
• Contact finish specification (gold mating surface)
• Shrouding configuration (4-wall shrouded)
• Insulation material composition (Polyamide/Nylon)
• Flammability compliance (UL94 V-0)

The substitute part 3-794632-2 qualifies as a direct equivalent based on complete alignment with all critical parameters. Variation occurs only in packaging format (tray versus standard packaging) and post-contact finish material (tin versus tin-lead), which do not affect functional compatibility or mating performance.

Parameter Comparison

Engineering Selection Recommendations

794632-2 (Main Part): This part is suitable for applications where RoHS non-compliance is acceptable and tin-lead post finishes are specified. The standard packaging format supports typical component handling and storage workflows. Product status is Active with established supply chain availability.

3-794632-2 (Substitute): This part is the preferred selection for applications requiring RoHS compliance. The tray packaging format provides alternative handling and bulk ordering options. The tin post finish (without lead) maintains functional compatibility while addressing environmental and regulatory requirements. Product status is Active with significantly higher inventory availability (20,574 pieces versus 964 pieces).

Selection Criteria:

• Choose 3-794632-2 when RoHS compliance is mandated by design specifications, procurement policies, or end-use regulations
• Choose 794632-2 when RoHS non-compliance is explicitly permitted and tin-lead post finishes are required
• Both parts deliver identical electrical performance, mechanical fit, and thermal characteristics
• Packaging format selection depends on inventory management and component handling procedures

Frequently Asked Questions (FAQ)

Q: Are 794632-2 and 3-794632-2 electrically interchangeable?

A: Yes. Both parts operate at identical voltage ratings (250V), current capacity (varies by wire gauge), and temperature ranges (-40°C to 105°C). Contact materials, finishes, and mating surfaces are functionally equivalent.

Q: What is the difference between tin-lead and tin post finishes?

A: The post finish (solder tail) differs between parts. The 794632-2 uses tin-lead; the 3-794632-2 uses tin. Both finishes support press-fit and solder termination methods. The tin finish in 3-794632-2 aligns with RoHS compliance requirements.

Q: Can I use 3-794632-2 as a direct replacement for 794632-2 in existing designs?

A: Yes, provided RoHS compliance is acceptable or required. The connector geometry, electrical ratings, and mechanical mounting are identical. Solder joint performance with tin post finish is equivalent to tin-lead.

Q: What does the packaging difference (standard versus tray) mean?

A: Packaging format affects component handling, storage, and bulk ordering. Tray packaging (3-794632-2) is typically used for automated assembly and high-volume procurement. Standard packaging (794632-2) supports conventional component distribution. Functional performance is unaffected.

Q: Why does 3-794632-2 have higher inventory availability?

A: The 3-794632-2 variant (20,574 pieces) has greater stock than 794632-2 (964 pieces) due to RoHS compliance demand and tray packaging format preference in current supply chains.

Q: Are both parts suitable for -40°C to 105°C operating environments?

A: Yes. Both parts maintain identical operating temperature specifications and UL94 V-0 flammability ratings across this range.

Q: What is the significance of the "3-" prefix in part number 3-794632-2?

A: The "3-" prefix indicates a variant designation within the TE Connectivity product line, distinguishing packaging format and compliance status while maintaining the base product number 794632.

Q: Can these connectors be used in high-reliability applications?

A: Both parts support general-purpose applications with UL94 V-0 material certification and gold-plated mating contacts. Application-specific reliability requirements should be evaluated against design specifications.
