TE Connectivity 350824-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350824-2 is a 2-position header connector from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications. This through-hole mounted connector features gold-plated mating contacts and tin-lead plated posts for solder termination. The connector is currently active in production with 691 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. The primary reason for identifying substitute parts is to provide alternative sourcing options when the original part number becomes unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 350824-2 is determined by strict equivalence across the following critical parameters:

• Connector Type: Header configuration required
• Contact Type: Female socket contacts required
• Number of Positions: Exactly 2 positions required
• Pitch - Mating: 0.250" (6.35mm) spacing required
• Mounting Type: Through-hole mounting required
• Termination Method: Solder termination required
• Contact Finish - Mating: Gold plating required
• Insulation Material: Polyamide (PA) or Nylon required
• Contact Material: Phosphor bronze required
• Material Flammability Rating: UL94 V-0 required

The substitute part 350824-4 maintains all critical electrical and mechanical parameters while differing in packaging configuration and post-contact finish specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 350824-2 and 350824-4 are active production parts from TE Connectivity's Universal MATE-N-LOK series and maintain identical mechanical and electrical connector specifications.

350824-2 is suitable for applications where tin-lead post finish is required or where RoHS non-compliant components are acceptable within the design framework.

350824-4 is suitable for applications requiring ROHS3 compliance. This part features tin post finish instead of tin-lead and is available in bulk packaging. The higher inventory level (1399 pieces) provides greater availability for high-volume production requirements.

Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating (MSL 1), indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Are the 350824-2 and 350824-4 mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical dimensions, including 0.250" (6.35mm) pitch, 0.550" (13.97mm) insulation height, and 0.155" (3.94mm) contact post length. Through-hole mounting and solder termination are identical.

Q: What is the difference between the post finishes?

A: The 350824-2 features tin-lead plated posts, while the 350824-4 features tin-plated posts. Both are suitable for solder termination. The tin-lead finish in the 350824-2 contributes to its RoHS non-compliant status.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. The 350824-4 is ROHS3 compliant and is the appropriate choice for applications subject to RoHS directives. The 350824-2 remains available for legacy designs or applications where RoHS compliance is not required.

Q: Does packaging affect electrical or mechanical performance?

A: No. The standard and bulk packaging options do not affect connector performance. Packaging selection is based on procurement and inventory management requirements.

Q: Are both parts suitable for the same operating environments?

A: Yes. Both connectors carry identical UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, indicating equivalent environmental performance characteristics.

Q: What is the mating contact finish specification?

A: Both parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness, ensuring consistent contact resistance and corrosion resistance across both part numbers.
