TE Connectivity 350765-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350765-3 is a 15-position header connector from the Universal MATE-N-LOK series, designed for through-hole PCB mounting with board-to-cable/wire applications. This connector features a 0.250" (6.35mm) pitch, gold-plated mating contacts, and solder termination. The part is currently active in production with 972 units in stock. Substitute parts are identified to provide alternative configurations when the original specification requires different connector types, fastening mechanisms, or compliance certifications while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 350765-3 and 350765-5 is based on the following criteria:

Compatible Parameters:

• Both parts share the same base product number (350765) and Universal MATE-N-LOK series designation
• Identical 15-position configuration with 3-row layout
• Matching 0.250" (6.35mm) pitch and row spacing
• Both employ through-hole solder termination
• Identical contact material (Phosphor Bronze) and mating contact finish (Gold at 30.0µin thickness)
• Both use Polyamide (PA) Nylon insulation
• Identical circular contact shape
• Both classified as MSL 1 (Unlimited moisture sensitivity)

Differentiating Parameters:

• Connector type: 350765-3 is a header; 350765-5 is a socket
• Fastening mechanism: 350765-3 uses locking ramp; 350765-5 uses latch lock
• Insulation height: 350765-3 measures 0.550" (13.97mm); 350765-5 measures 0.580" (14.73mm)
• Contact finish on post: 350765-3 has tin-lead; 350765-5 has tin
• RoHS compliance: 350765-3 is not applicable; 350765-5 is RoHS compliant

The 350765-5 serves as a direct substitute when socket-type connectors are required instead of header configurations, or when RoHS compliance is mandated.

Parameter Comparison

Engineering Selection Recommendations

350765-3 Selection Criteria:

• Applications requiring header-type connectors for board-to-cable/wire interconnection
• Systems where locking ramp fastening mechanism is specified
• Designs with 0.550" (13.97mm) insulation height clearance requirements
• Tin-lead post finish compatibility with existing assembly processes

350765-5 Selection Criteria:

• Applications requiring socket-type connectors for board-to-board or cable configurations
• Designs mandating RoHS compliance certification
• Systems where latch lock fastening mechanism is preferred
• Designs with 0.580" (14.73mm) insulation height clearance requirements
• Tin post finish compatibility with assembly specifications

Both parts maintain active product status and are suitable for new designs. The 350765-5 provides enhanced compliance posture through RoHS certification, while the 350765-3 remains available for legacy or non-regulated applications. Selection between these parts depends on connector type requirements (header versus socket) and regulatory compliance mandates rather than electrical performance, as both share identical contact materials, pitch specifications, and mating contact finishes.

Frequently Asked Questions (FAQ)

Q: Can the 350765-3 and 350765-5 be used interchangeably in the same circuit?

A: Direct interchangeability is limited by connector type. The 350765-3 is a header connector, while the 350765-5 is a socket connector. Both are female socket contact types within the Universal MATE-N-LOK series and share identical pitch (0.250"), row configuration (3 rows), and contact specifications. Interchangeability depends on whether the mating connector in the application is designed for header or socket engagement.

Q: What is the significance of the different fastening types between these parts?

A: The 350765-3 uses a locking ramp fastening mechanism, while the 350765-5 uses a latch lock mechanism. These are different mechanical retention systems within the MATE-N-LOK series. The fastening type affects how the connector is secured to its mating counterpart and should be selected based on application requirements and mating connector specifications.

Q: Does the insulation height difference between 350765-3 (0.550") and 350765-5 (0.580") affect compatibility?

A: The 0.030" (0.76mm) difference in insulation height is a physical dimension that must be accommodated in PCB layout and enclosure design. This difference does not affect electrical compatibility but requires verification of mechanical clearance in the target application.

Q: What is the impact of RoHS compliance on part selection?

A: The 350765-5 is RoHS compliant, while the 350765-3 is not applicable for RoHS classification. For applications subject to RoHS regulations (such as consumer electronics in certain markets), the 350765-5 is the appropriate selection. For non-regulated applications or legacy designs, either part may be used based on other technical requirements.

Q: Are the contact finishes identical between these parts?

A: Mating contact finishes are identical (gold at 30.0µin thickness) on both parts. Post contact finishes differ: the 350765-3 has tin-lead, while the 350765-5 has tin. This difference may affect solder joint characteristics and should be considered in assembly process specifications.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these connectors have no moisture sensitivity restrictions. They do not require special handling, storage, or baking procedures prior to soldering and can be stored under standard conditions without time limitations.
