Key Parameters

Substitute Part Grouping Explanation

Substitution between TE Connectivity 350789-2 and 350789-3 is determined by equivalence in the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin (identical)
• Number of Positions: 3 (identical)
• Pitch - Mating: 0.250" (6.35mm) (identical)
• Contact Material: Phosphor Bronze (identical)
• Contact Finish - Mating: Gold at 30.0µin (0.76µm) (identical)

Mechanical Compatibility Parameters:

• Connector Type: Header (identical)
• Mounting Type: Through Hole (identical)
• Termination: Solder (identical)
• Shrouding: Shrouded - 4 Wall (identical)
• Fastening Type: Locking Ramp (identical)
• Insulation Material: Polyamide (PA), Nylon (identical)
• Insulation Height: 0.550" (13.97mm) (identical)
• Contact Length - Post: 0.155" (3.94mm) (identical)
• Contact Shape: Circular (identical)

Series Compatibility:

• Series: Universal MATE-N-LOK (identical)

Both parts are Active products within the same series and maintain identical form, fit, and function characteristics. The primary distinction between these parts is packaging configuration and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

350789-2 Selection Criteria:

• Applications requiring RoHS non-compliant components
• Designs where REACH Affected status is acceptable
• Standard packaging requirements
• Current inventory availability of 750 pieces

350789-3 Selection Criteria:

• Applications requiring RoHS Compliant components
• Designs subject to environmental regulations mandating RoHS compliance
• Bulk packaging requirements
• Higher inventory availability of 5009 pieces
• Applications where REACH compliance status is critical

Both parts maintain identical electrical and mechanical specifications within the Universal MATE-N-LOK series. Selection between 350789-2 and 350789-3 is determined by regulatory compliance requirements and packaging preferences rather than functional performance differences. The substitute relationship is bidirectional for applications where compliance requirements are equivalent.

Frequently Asked Questions (FAQ)

Q: Are 350789-2 and 350789-3 electrically interchangeable?

A: Yes. Both parts feature identical contact type (Male Pin), number of positions (3), mating pitch (0.250"/6.35mm), contact material (Phosphor Bronze), and contact finish specifications (Gold at 30.0µin mating surface, Tin post finish). Electrical performance is equivalent.

Q: Are 350789-2 and 350789-3 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including mounting type (Through Hole), termination method (Solder), shrouding configuration (Shrouded - 4 Wall), fastening type (Locking Ramp), insulation material (Polyamide/Nylon), and physical dimensions (0.550" insulation height, 0.155" post length). Form and fit are equivalent.

Q: What is the primary difference between these parts?

A: The primary differences are RoHS compliance status (350789-2 is non-compliant; 350789-3 is compliant), REACH status (350789-2 is REACH Affected; 350789-3 is Vendor Undefined), packaging configuration (350789-3 is Bulk), and inventory levels (350789-3 has higher stock availability).

Q: Can I substitute 350789-3 for 350789-2 in an existing design?

A: Substitution is valid when the design does not require RoHS non-compliant components. If the application is subject to RoHS regulations or environmental compliance mandates, 350789-3 is the appropriate selection. Both parts operate identically within the Universal MATE-N-LOK series.

Q: Can I substitute 350789-2 for 350789-3?

A: Substitution is valid only when RoHS compliance is not a design requirement. If the application mandates RoHS compliance, 350789-2 is not suitable. Verify regulatory requirements before substitution.

Q: What packaging options are available?

A: 350789-2 packaging is not specified in the product data. 350789-3 is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: Are both parts currently available?

A: Yes. 350789-2 has 750 pieces in stock. 350789-3 has 5009 pieces in stock. Both are Active products from TE Connectivity AMP Connectors.

Q: What series do these connectors belong to?

A: Both parts are members of the Universal MATE-N-LOK series, ensuring compatibility with corresponding receptacle connectors and mating components within this series.

Q: What is the moisture sensitivity level?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating Unlimited shelf life without special moisture control requirements.
