TE Connectivity 350825-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350825-2 is a 3-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 744 units 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, accommodate different packaging requirements, or address compliance variations while maintaining functional compatibility in the application.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity 350825-4 is identified as a direct substitute for the 350825-2 based on the following equivalence criteria:

Electrical Compatibility Parameters:

• Identical number of positions (3)
• Identical mating pitch (0.250" / 6.35mm)
• Identical contact type (Female Socket)
• Identical contact material (Phosphor Bronze)
• Identical mating contact finish (Gold) and thickness (30.0µin / 0.76µm)

Mechanical Compatibility Parameters:

• Identical connector type (Header)
• Identical mounting type (Through Hole)
• Identical termination method (Solder)
• Identical insulation material (Polyamide / Nylon)
• Identical insulation height (0.550" / 13.97mm)
• Identical contact shape (Circular)
• Identical fastening type (Locking Ramp)
• Identical series designation (Universal MATE-N-LOK)
• Identical flammability rating (UL94 V-0)

The primary differences between these parts are packaging format and compliance certifications, which do not affect functional interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

Both the 350825-2 and 350825-4 are active production parts from TE Connectivity and maintain identical electrical and mechanical specifications for connector functionality. The parts are functionally interchangeable in applications where the mating interface, contact configuration, and through-hole mounting requirements are specified.

Compliance Considerations:

The 350825-4 is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union regulatory requirements. The 350825-2 is RoHS non-compliant and REACH affected, which may restrict its use in certain regulated markets or applications with specific compliance mandates.

Post Contact Finish Difference:

The 350825-2 features tin-lead plated posts, while the 350825-4 features tin-plated posts. Both are suitable for solder termination. The tin-lead composition in the 350825-2 reflects older manufacturing standards, while the tin plating in the 350825-4 aligns with current lead-free soldering practices.

Packaging and Availability:

The 350825-4 is available in bulk packaging with significantly higher inventory (3736 units) compared to the 350825-2 (744 units), providing greater availability for high-volume applications.

Selection between these parts should be based on compliance requirements, supply chain considerations, and soldering process specifications for the application.

Frequently Asked Questions (FAQ)

Q: Are the 350825-2 and 350825-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including mounting type (through-hole), insulation dimensions (0.550" height), contact shape (circular), and fastening type (locking ramp). They mount identically on printed circuit boards and accept the same mating connectors.

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

A: The 350825-2 uses tin-lead plating on the solder posts, while the 350825-4 uses tin plating. Both finishes are compatible with solder termination processes. The tin-lead composition in the 350825-2 is associated with traditional lead-containing solder processes, whereas the tin finish in the 350825-4 is compatible with lead-free soldering.

Q: Can I substitute the 350825-4 for the 350825-2 in an existing design?

A: Functional substitution is possible due to identical electrical and mechanical parameters. However, compliance requirements must be evaluated. If the application requires RoHS compliance or REACH compliance, the 350825-4 is the appropriate choice. If the design was originally specified with the 350825-2, soldering process compatibility should be confirmed.

Q: What is the significance of the packaging difference?

A: The 350825-2 is supplied in standard packaging, while the 350825-4 is supplied in bulk packaging. Bulk packaging typically accommodates higher-volume manufacturing requirements and may offer cost advantages for large-scale production. The connector specifications and functionality remain identical regardless of packaging format.

Q: Are both parts currently in production?

A: Yes. Both the 350825-2 and 350825-4 are listed as active products. The 350825-4 has higher inventory availability (3736 units) compared to the 350825-2 (744 units).

Q: What are the mating specifications for these connectors?

A: Both connectors are 3-position headers with a 0.250" (6.35mm) mating pitch. They feature female socket contacts with gold plating (30.0µin / 0.76µm thickness) and circular contact geometry. They are designed for board-to-cable/wire applications using the Universal MATE-N-LOK series interface.

Q: Do these connectors have current or voltage ratings specified?

A: Current and voltage ratings are not provided in the available specifications for these connector models. Application-specific electrical requirements should be confirmed with TE Connectivity technical documentation or the connector datasheet.
