TE Connectivity 350827-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350827-2 is a 6-position header connector from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications with through-hole solder termination. This connector features gold-plated mating contacts and tin-lead plated posts, operating with a 0.250" (6.35mm) pitch configuration across 3 rows. The component is classified as Active product status with 832 pieces currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications, allowing for component interchangeability in applications where the primary part becomes unavailable or when alternative packaging or compliance requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 350827-2 and 350827-4 is established through equivalence of the following critical parameters:

Mechanical Compatibility Parameters:

• Identical connector type (Header), contact type (Female Socket), and style (Board to Cable/Wire)
• Matching position count (6 positions) with identical pitch (0.250" / 6.35mm) and row configuration (3 rows)
• Equivalent row spacing (0.250" / 6.35mm) and mounting method (Through Hole)
• Identical termination method (Solder) and fastening mechanism (Locking Ramp)

Electrical & Material Parameters:

• Matching contact material (Phosphor Bronze) and mating contact finish (Gold) with identical thickness specification (30.0µin / 0.76µm)
• Equivalent insulation material (Polyamide/Nylon) and insulation height (0.550" / 13.97mm)
• Identical contact shape (Circular) and contact length (0.155" / 3.94mm)
• Matching material flammability rating (UL94 V-0)
• Identical moisture sensitivity level (MSL 1 - Unlimited)

Variance Parameters:

• Contact finish on posts differs: 350827-2 uses Tin-Lead; 350827-4 uses Tin
• Packaging differs: 350827-2 standard packaging; 350827-4 bulk packaging
• RoHS compliance status differs: 350827-2 is RoHS non-compliant; 350827-4 is ROHS3 compliant
• REACH status differs: 350827-2 is Vendor Undefined; 350827-4 is REACH Unaffected

Parameter Comparison

Engineering Selection Recommendations

Both the 350827-2 and 350827-4 maintain Active product status and are manufactured by TE Connectivity within the Universal MATE-N-LOK series. The parts are mechanically and electrically equivalent across all critical connector parameters including position count, pitch, row configuration, contact materials, and mating contact finish specifications.

The primary distinction between these parts relates to regulatory compliance and post-contact finish composition. The 350827-4 provides ROHS3 compliance and REACH Unaffected status, whereas the 350827-2 is RoHS non-compliant with Vendor Undefined REACH status. Applications subject to RoHS3 or REACH regulatory requirements should specify the 350827-4 variant.

The post-contact finish differs between parts: 350827-2 features Tin-Lead plating while 350827-4 uses Tin plating. This distinction may influence solder joint characteristics and thermal cycling performance in specific assembly processes. The 350827-4 bulk packaging option provides higher inventory availability at 1344 pieces compared to 832 pieces for the 350827-2.

Frequently Asked Questions (FAQ)

Q: Are the 350827-2 and 350827-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 6-position configuration, 0.250" (6.35mm) pitch, 3-row layout, through-hole mounting, and solder termination. The physical footprint and mating interface are equivalent.

Q: What is the difference in post-contact finish between these parts?

A: The 350827-2 uses Tin-Lead plating on the posts, while the 350827-4 uses Tin plating. Both finishes are suitable for solder termination; however, the composition may affect solder wetting characteristics and thermal cycling behavior depending on assembly parameters.

Q: Which part should be selected for RoHS-compliant applications?

A: The 350827-4 is ROHS3 compliant and should be specified for applications requiring RoHS compliance. The 350827-2 is RoHS non-compliant and is not suitable for such applications.

Q: What is the significance of the packaging difference?

A: The 350827-2 is supplied in standard packaging, while the 350827-4 is supplied in bulk packaging. The bulk option (350827-4) provides higher inventory availability with 1344 pieces in stock compared to 832 pieces for the 350827-2, which may be advantageous for high-volume production requirements.

Q: Are the mating contact specifications identical?

A: Yes. Both parts feature gold-plated mating contacts with identical thickness specification of 30.0µin (0.76µm), ensuring equivalent electrical performance and contact reliability.

Q: What is the REACH compliance status for each part?

A: The 350827-4 is REACH Unaffected, indicating full compliance with REACH regulations. The 350827-2 has Vendor Undefined REACH status and should not be specified for applications requiring confirmed REACH compliance.

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

A: Operating temperature specifications are not provided in the technical parameters for either part. Thermal performance data must be obtained from the manufacturer's detailed technical documentation.
