TE Connectivity 640620-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640620-9 is a 9-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, free hanging in-line and right angle mounting options, and locking ramp fastening. The part is currently active in production with 698 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be required due to inventory availability, packaging format changes, or compliance requirement updates.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 640620-9 are identified based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (9)
• Contact type (Female Socket)
• Pitch (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Series designation (MTA-100)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

The substitute part 3-640620-9 maintains all electrical and mechanical parameters identical to the main part. The primary difference is the contact finish specification (Tin versus Tin-Lead) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

640620-9 Selection Criteria: The 640620-9 is appropriate for applications where tin-lead contact finish is specified or required. This part maintains RoHS non-compliant status and is suitable for legacy systems or applications where RoHS compliance is not mandated. Current inventory of 698 pieces supports immediate availability for production requirements.

3-640620-9 Selection Criteria: The 3-640620-9 substitute part is appropriate for applications requiring ROHS3 compliance. The tin contact finish meets modern environmental and regulatory standards while maintaining identical electrical and mechanical performance. Higher inventory availability (931 pieces) provides extended supply assurance. This part is the preferred selection for new designs and applications subject to RoHS regulations.

Compliance Considerations: Selection between these parts is primarily determined by RoHS compliance requirements. Both parts maintain identical connector specifications, pitch, position count, termination method, and wire gauge compatibility. The contact finish difference (tin-lead versus tin) does not affect electrical performance or mechanical fit within the MTA-100 series specification.

Frequently Asked Questions (FAQ)

Q: Are the 640620-9 and 3-640620-9 mechanically interchangeable?

A: Yes. Both parts are 9-position receptacle connectors with identical pitch (0.100"), mounting type (free hanging in-line and right angle), fastening type (locking ramp), and contact finish thickness (80.0µin). They are mechanically interchangeable within MTA-100 series applications.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 640620-9 features tin-lead contact finish, while the 3-640620-9 features tin contact finish. Both finishes provide equivalent electrical conductivity and contact resistance at 80.0µin thickness. The primary distinction is regulatory compliance: tin-lead is RoHS non-compliant, while tin is ROHS3 compliant.

Q: Can I use the 3-640620-9 as a direct replacement for the 640620-9?

A: The 3-640620-9 is electrically and mechanically equivalent to the 640620-9. Selection depends on compliance requirements. If RoHS compliance is required, the 3-640620-9 is the appropriate choice. If legacy tin-lead specifications are mandated, the 640620-9 remains the correct part.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination allows direct connection of discrete or ribbon cable without stripping insulation. The connector contacts pierce the cable insulation during insertion, establishing electrical connection. Both parts support this termination method for 22 AWG wire.

Q: Are both parts suitable for ribbon cable applications?

A: Yes. Both the 640620-9 and 3-640620-9 support discrete or ribbon cable wire types with 22 AWG gauge. The IDC termination method accommodates standard ribbon cable configurations within MTA-100 series specifications.

Q: What is the significance of MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture sensitivity precautions required. Both parts carry MSL 1 rating, meaning they can be stored and handled without special moisture control measures.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The 640620-9 is supplied in unspecified packaging, while the 3-640620-9 is supplied in bulk packaging. Packaging format does not affect connector electrical performance, mechanical fit, or compatibility. Selection between packaging options depends on inventory management and procurement requirements.

Q: Are both parts currently in active production?

A: Yes. Both the 640620-9 and 3-640620-9 maintain active product status with TE Connectivity. Current inventory levels are 698 pieces and 931 pieces respectively, supporting ongoing production requirements.
