Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 350834-2 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Criteria:

• Connector type (Header)
• Contact type (Female Socket)
• Number of positions (6)
• Pitch - mating (0.250" / 6.35mm)
• Number of rows (3)
• Row spacing - mating (0.250" / 6.35mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Contact finish thickness - mating (30.0µin / 0.76µm)
• Insulation material (Polyamide / Nylon)
• Insulation height (0.550" / 13.97mm)
• Contact length - post (0.215" / 5.46mm)
• Material flammability rating (UL94 V-0)
• Series designation (Universal MATE-N-LOK)

The identified substitute part 350834-4 maintains complete equivalence across all these parameters, ensuring direct functional and mechanical interchangeability in applications requiring the 350834-2 connector.

Parameter Comparison

Engineering Selection Recommendations

350834-2 Selection Criteria: The 350834-2 is appropriate for applications where RoHS non-compliant components are acceptable and tin-lead post plating is specified. This part maintains active product status and is available in standard inventory quantities (776 pieces).

350834-4 Selection Criteria: The 350834-4 serves as the primary substitute for applications requiring RoHS compliance. The contact finish on the post differs from the main part (tin versus tin-lead), representing a material composition change that does not affect mechanical or electrical interchangeability. This part is RoHS compliant and available in bulk packaging with higher inventory levels (1,071 pieces). Both parts share identical electrical and mechanical specifications across all critical parameters.

Compliance Considerations: Selection between these parts should be based on regulatory requirements. The 350834-4 is mandated for applications subject to RoHS directives. Both parts maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels (MSL 1).

Frequently Asked Questions (FAQ)

Q: Are the 350834-2 and 350834-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.250"), number of positions (6), row configuration (3 rows), insulation height (0.550"), and contact length (0.215"). They mount identically in through-hole applications and accept the same mating connectors.

Q: What is the difference between the contact finishes on the post?

A: The 350834-2 features tin-lead plating on the post, while the 350834-4 features tin plating. Both finishes are compatible with standard solder termination processes and do not affect electrical performance or mechanical fit.

Q: Which part should be selected for new designs?

A: The 350834-4 is recommended for new designs due to its RoHS compliance status. This part meets current regulatory requirements and maintains full compatibility with the 350834-2 across all functional parameters.

Q: Does packaging differ between these parts?

A: Yes. The 350834-2 packaging is not specified in standard documentation, while the 350834-4 is supplied in bulk packaging. Packaging selection may influence procurement and handling procedures but does not affect connector performance.

Q: Are both parts currently in production?

A: Yes. Both the 350834-2 and 350834-4 maintain active product status within TE Connectivity's portfolio, ensuring continued availability and support.

Q: Can the 350834-4 replace the 350834-2 in existing applications?

A: Yes. The 350834-4 provides complete functional and mechanical replacement for the 350834-2. The only consideration is RoHS compliance status, which may be required depending on application regulations and customer specifications.
