Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640622-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MTA-100)
• Connector type (Receptacle)
• Number of positions (10)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (26 AWG)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Feed-through feature

Allowable Variations:

• Contact finish composition (tin-lead to tin)
• Product status (obsolete to active)
• RoHS compliance status
• Packaging configuration

The substitute part 4-640622-0 maintains complete electrical and mechanical compatibility with the original 1-640622-0 while offering improved compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 4-640622-0

The 4-640622-0 is the direct equivalent substitute for the obsolete 1-640622-0. Both connectors share identical electrical and mechanical specifications within the MTA-100 series, including connector type, position count, pitch, termination method, and wire gauge compatibility.

Compliance Advantages:

The 4-640622-0 offers RoHS compliance status, whereas the 1-640622-0 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations or customer requirements mandating compliant components. The contact finish differs (tin versus tin-lead), with the 4-640622-0 utilizing pure tin plating while maintaining the same 80.0µin thickness specification.

Product Status:

The 4-640622-0 maintains active product status with higher inventory availability (1934 pieces in stock versus 915 pieces for the obsolete part), ensuring long-term supply chain reliability and reduced lead times for new designs and production runs.

Functional Equivalence:

Both parts are mechanically and electrically interchangeable within the same application context. The connector geometry, IDC termination interface, locking ramp fastening mechanism, and feed-through design are identical. Wire gauge compatibility (26 AWG) and cable type support (discrete or ribbon) remain unchanged.

Frequently Asked Questions (FAQ)

Q: Are the 1-640622-0 and 4-640622-0 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), mounting type (free hanging in-line and right angle), fastening mechanism (locking ramp), and physical form factor within the MTA-100 series.

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

A: The 1-640622-0 uses tin-lead contact finish, while the 4-640622-0 uses pure tin finish. Both maintain the same 80.0µin (2.03µm) thickness. The tin finish in the 4-640622-0 aligns with RoHS compliance requirements that restrict lead content in electronic components.

Q: Can I use the 4-640622-0 as a direct replacement in existing designs?

A: Yes. The 4-640622-0 is electrically and mechanically equivalent to the 1-640622-0. The connector interfaces, IDC termination compatibility, and wire gauge specifications are identical, enabling direct substitution in PCB layouts and cable assemblies.

Q: Why is the 1-640622-0 listed as obsolete?

A: The 1-640622-0 has reached end-of-life status in TE Connectivity's product portfolio. The 4-640622-0 represents the active equivalent, offering improved compliance and ongoing manufacturing support.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS compliance indicates the connector meets restrictions on hazardous substances, particularly lead content. The 4-640622-0 RoHS-compliant status is required for applications subject to RoHS regulations or customer specifications mandating compliant components.

Q: Are there packaging differences between these parts?

A: The 1-640622-0 packaging specification is not defined in the available data. The 4-640622-0 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What wire gauges are compatible with these connectors?

A: Both connectors support 26 AWG wire gauge for discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the 1-640622-0 and 4-640622-0 have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
