TE Connectivity 350763-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350763-3 is a 9-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 maintains active product status and is currently in stock with 1109 units available. Substitute parts are identified when equivalent electrical and mechanical specifications are required for applications where the original part number is unavailable or when alternative packaging configurations are needed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across electrical and mechanical parameters. The 350763-3 and its identified substitute 350763-5 share identical specifications for all critical mating and mechanical characteristics:

Key Parameters Determining Substitutability:

• Connector type, contact type, and style (Header, Female Socket, Board to Cable/Wire)
• Position count and arrangement (9 positions in 3 rows)
• Pitch and row spacing (0.250" mating pitch and row spacing)
• Mounting method and termination type (Through Hole, Solder)
• Mating contact finish and thickness (Gold, 30.0µin)
• Insulation material and dimensions (Polyamide/Nylon, 0.550" height)
• Contact material and shape (Phosphor Bronze, Circular)
• Fastening mechanism (Locking Ramp)
• Flammability rating (UL94 V-2)

The substitute part 350763-3 differs only in packaging configuration and post contact finish specification, with no impact on functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 350763-3 and 350763-5 are active products from TE Connectivity's Universal MATE-N-LOK series and are functionally equivalent for board-to-cable/wire connector applications requiring 9-position through-hole solder termination with 0.250" pitch configuration.

350763-3 Selection Criteria:

• Standard packaging configuration
• Tin-Lead post contact finish
• Not applicable RoHS status
• 1109 units in current inventory

350763-5 Selection Criteria:

• Bulk packaging configuration
• Tin post contact finish
• ROHS3 Compliant certification
• 963 units in current inventory

The selection between these parts is determined by packaging requirements, regulatory compliance mandates, and inventory availability. Both parts maintain identical mechanical and electrical mating characteristics, insulation specifications, and flammability ratings. The post contact finish difference (Tin-Lead versus Tin) reflects manufacturing process variations without impact on functional compatibility in equivalent solder termination applications.

Frequently Asked Questions (FAQ)

Q: Are the 350763-3 and 350763-5 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 9-position configuration, 0.250" mating pitch, 3-row arrangement, 0.550" insulation height, and through-hole mounting dimensions. They are mechanically interchangeable in board-level applications.

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

A: The 350763-3 features tin-lead plated posts, while the 350763-5 features tin-plated posts. Both are suitable for solder termination applications. The 350763-5 tin finish aligns with ROHS3 compliance requirements.

Q: Does the RoHS compliance status affect functional performance?

A: RoHS compliance status reflects manufacturing material composition and environmental regulatory adherence. The 350763-5 ROHS3 Compliant designation indicates conformance to restricted substance directives. Functional performance in equivalent applications is not affected by this designation.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the design accommodates the specified packaging configuration. The 350763-3 standard packaging and 350763-5 bulk packaging are functionally equivalent. Verify packaging requirements for your application before selection.

Q: What is the significance of the Universal MATE-N-LOK series designation?

A: Universal MATE-N-LOK is the connector series classification from TE Connectivity. Both parts belong to this series, ensuring compatibility with corresponding mating connectors and accessories within the MATE-N-LOK product family.

Q: Are there any temperature or voltage limitations for these connectors?

A: Operating temperature and voltage rating specifications are not provided in the available technical parameters for these parts. Consult the complete datasheet or contact the manufacturer for these specifications if required for your application.

Q: What does MSL 1 (Unlimited) indicate?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the lowest moisture sensitivity classification. These connectors do not require special moisture control handling during storage, transportation, or assembly.
