TE Connectivity 640622-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640622-9 is a 9-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish, feed-through capability, and locking ramp fastening. The part is currently in active product status with 987 units in stock.

Identification of equivalent and substitute parts becomes necessary when the primary part reaches end-of-life status, when inventory constraints occur, or when design requirements permit alternative contact finishes or packaging configurations within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640622-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Rectangular receptacle
• Number of positions: 9
• Pitch: 0.100" (2.54mm)
• Number of rows: 1
• Contact type: Female socket
• Cable termination: IDC
• Wire gauge: 26 AWG
• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Locking ramp
• Contact finish thickness: 80.0µin (2.03µm)
• Series: MTA-100

Variable Parameters Permitting Substitution:

• Contact finish material (tin-lead versus tin)
• Packaging configuration (bulk versus standard)
• Product status (active versus obsolete)
• RoHS compliance level

The substitute part 3-640622-9 maintains complete electrical and mechanical compatibility with the 640622-9 across all mandatory parameters. The primary differences are contact finish composition (tin versus tin-lead) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (640622-9): The 640622-9 is the recommended selection for new designs and active production applications. This part maintains active product status with established supply chain availability. The tin-lead contact finish provides proven performance characteristics in legacy systems. RoHS non-compliance status indicates this part is suitable for applications without RoHS regulatory requirements.

Substitute Part Selection (3-640622-9): The 3-640622-9 serves as a direct functional substitute when the primary part becomes unavailable or when design requirements permit ROHS3 compliance. This part is currently classified as obsolete, indicating limited future availability. The tin contact finish (without lead) provides equivalent electrical and mechanical performance while meeting modern environmental compliance standards. The bulk packaging configuration may be advantageous for high-volume procurement scenarios.

Compliance Considerations: Selection between these parts should account for regulatory environment and end-application requirements. The 640622-9 (tin-lead) is appropriate for non-RoHS applications. The 3-640622-9 (tin, ROHS3 compliant) is appropriate for applications subject to RoHS3 regulations or customer specifications requiring lead-free contact finishes.

Frequently Asked Questions (FAQ)

Q: Are the 640622-9 and 3-640622-9 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications across all critical parameters including pitch (0.100"), number of positions (9), contact type (female socket), wire gauge (26 AWG), and contact finish thickness (80.0µin). The difference in contact finish material (tin-lead versus tin) does not affect electrical interchangeability.

Q: What is the significance of the contact finish difference between these parts?

A: The 640622-9 features tin-lead contact finish, while the 3-640622-9 features tin contact finish. Both finishes provide equivalent electrical conductivity and contact resistance at the specified thickness of 80.0µin (2.03µm). The primary distinction is regulatory compliance: tin-lead is non-RoHS compliant, while tin is ROHS3 compliant. Selection depends on application regulatory requirements.

Q: Can I use the 3-640622-9 as a direct replacement for the 640622-9 in existing designs?

A: Mechanical and electrical compatibility is complete. The 3-640622-9 maintains identical mounting type, fastening mechanism, pitch, and contact configuration. However, the obsolete product status of the 3-640622-9 indicates limited future availability, making it unsuitable as a long-term replacement strategy. For new designs, the active 640622-9 is the appropriate selection.

Q: What does the packaging difference (standard versus bulk) mean for component selection?

A: Packaging configuration affects procurement and handling but does not impact electrical or mechanical performance. Standard packaging (640622-9) is typical for general distribution. Bulk packaging (3-640622-9) is used for high-volume direct procurement from the manufacturer. Selection depends on order quantity and supply chain requirements.

Q: Are there any performance differences between these connectors in high-frequency or high-current applications?

A: No performance differences exist within the specified electrical parameters. Both parts are rated for identical wire gauge (26 AWG) and contact finish thickness (80.0µin). Performance characteristics are determined by these parameters, not by contact finish material composition at equivalent thickness.

Q: What is the MSL (Moisture Sensitivity Level) for both parts?

A: Both the 640622-9 and 3-640622-9 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
