TE Connectivity 350551-3 Socket Contact Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350551-3 is an active rectangular connector socket contact designed for the Universal MATE-N-LOK series. This component is a socket contact rated for 14-20 AWG wire gauges with tin contact finish and crimp termination. The part is supplied in bulk packaging and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging requirements differ from the standard bulk configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 350551-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: TE Connectivity AMP Connectors
• Series: Universal MATE-N-LOK
• Pin or Socket: Socket
• Contact Termination: Crimp
• Wire Gauge: 14-20 AWG
• Contact Finish: Tin
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

The substitute part 350537-3 meets all mandatory matching parameters. The primary difference between the main part and substitute is the packaging configuration: the 350551-3 is supplied in bulk packaging, while the 350537-3 is supplied in cut tape (CT) packaging. Both parts are functionally identical for connector assembly applications and maintain the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 350551-3 and 350537-3 are active products from TE Connectivity AMP Connectors and are functionally equivalent for Universal MATE-N-LOK socket contact applications. Selection between these parts is determined by packaging requirements and compliance specifications:

350551-3 (Bulk Packaging): Select this part number when bulk quantities are required for high-volume assembly operations or when inventory management systems accommodate loose component storage.

350537-3 (Cut Tape Packaging): Select this part number when cut tape packaging is required for automated pick-and-place assembly processes or when smaller quantity increments are needed. This part carries RoHS Compliant certification, which may be required for specific applications or regional compliance mandates.

Both parts share identical electrical and mechanical specifications, including wire gauge rating (14-20 AWG), crimp termination, tin contact finish, and unlimited moisture sensitivity rating. The choice between these substitutes is based on supply chain requirements, assembly methodology, and regulatory compliance needs rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can 350537-3 be used as a direct replacement for 350551-3?

A: Yes. Both parts are socket contacts for the Universal MATE-N-LOK series with identical electrical and mechanical specifications: 14-20 AWG wire gauge, crimp termination, and tin contact finish. The only difference is packaging format (bulk versus cut tape).

Q: What is the primary difference between these two part numbers?

A: The 350551-3 is supplied in bulk packaging, while the 350537-3 is supplied in cut tape (CT) packaging. This difference affects handling, storage, and integration with automated assembly equipment but does not affect the functional performance of the socket contact itself.

Q: Does the RoHS Compliant status of 350537-3 affect compatibility with 350551-3?

A: No. RoHS compliance is a regulatory and material composition specification that does not impact electrical or mechanical compatibility. The 350537-3 RoHS Compliant status makes it suitable for applications requiring RoHS certification, while the 350551-3 is marked as "Not applicable" for RoHS status.

Q: Are there any wire gauge or termination differences between these parts?

A: No. Both parts are rated for 14-20 AWG wire gauges and use crimp termination. They are electrically and mechanically identical in this regard.

Q: Which part should be selected for automated assembly processes?

A: The 350537-3 in cut tape packaging is designed for automated pick-and-place assembly systems. The 350551-3 in bulk packaging is suitable for manual assembly or high-volume loose component handling.

Q: Are both parts currently in active production?

A: Yes. Both the 350551-3 and 350537-3 maintain active product status with TE Connectivity AMP Connectors.
