TE Connectivity AMP Connectors 350838-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 350838-2 is a socket contact component within the MR (Miniature Rectangular) series of rectangular connectors. This part features gold plating on the contact finish with solder termination, designed for applications requiring reliable electrical connections in miniature rectangular connector assemblies. The 350838-2 is classified as obsolete, necessitating identification of equivalent substitute components for ongoing procurement and system maintenance. Substitute parts must maintain functional compatibility through matching core electrical and mechanical parameters while accommodating available product status alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 350838-2 is determined by the following critical parameters that must remain constant across equivalent components:

Mandatory Matching Parameters:

• Series: MR (Miniature Rectangular)
• Pin or Socket: Socket
• Contact Termination: Solder
• Base Product Number: 350838
• Category: Rectangular Connectors

Allowable Variation Parameters:

• Contact Finish: Gold or Tin plating are both acceptable finishes for socket contacts within the MR series
• Product Status: Active status parts are preferred substitutes for obsolete components
• Packaging: Variations in packaging format do not affect functional compatibility

The 350838-1 qualifies as a direct substitute based on shared base product number, identical socket configuration, solder termination method, and MR series classification. The primary distinction is the contact finish material (tin versus gold), which represents a material specification change rather than a functional incompatibility within this connector category.

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The 350838-2 is classified as obsolete. The 350838-1 is an active product within the same MR series and base product family, providing continuity of supply for ongoing applications. Both components share identical socket configuration, solder termination, and MSL classification.

For Compliance Considerations: The 350838-2 carries ROHS3 Compliant certification. The 350838-1 is listed as RoHS status not applicable. Both components are classified under ECCN EAR99 and HTSUS code 8536.90.4000. Selection between these parts should account for specific regulatory requirements applicable to the end application.

For Contact Finish Selection: The primary technical distinction is the contact finish material. The 350838-2 specifies gold plating at 30.0µin (0.76µm) thickness, while the 350838-1 uses tin plating. Contact finish selection impacts corrosion resistance, contact resistance characteristics, and long-term reliability in specific environmental conditions. Both finishes are standard for solder-terminated socket contacts in miniature rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 350838-1 directly replace the 350838-2 in existing assemblies?

A: The 350838-1 is functionally compatible as a socket contact within the MR series. Both parts share identical series classification, socket configuration, and solder termination. The contact finish difference (tin versus gold) represents a material specification change. Compatibility depends on application-specific requirements regarding contact finish performance and environmental exposure.

Q: What is the significance of the contact finish difference between these parts?

A: The 350838-2 features gold plating at 30.0µin (0.76µm) thickness, while the 350838-1 uses tin plating. Gold plating typically provides superior corrosion resistance and lower contact resistance over extended service life. Tin plating is suitable for standard applications with moderate environmental exposure. Selection should align with application requirements for contact reliability and environmental conditions.

Q: Why is the 350838-2 classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. The 350838-1, as an active product within the same base product family, provides a path for continued procurement and system support.

Q: Are there packaging differences between these substitute parts?

A: The 350838-2 packaging is listed as unspecified, while the 350838-1 is supplied in bulk packaging. Packaging format does not affect the functional performance of the socket contact component itself. Packaging selection should be based on procurement volume and inventory management requirements.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both the 350838-2 and 350838-1 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or processing.

Q: What compliance certifications apply to these parts?

A: Both components are classified under ECCN EAR99 and HTSUS code 8536.90.4000. The 350838-2 carries ROHS3 Compliant certification. The 350838-1 RoHS status is listed as not applicable. Compliance requirements should be verified against specific application and regulatory standards.
