Substitute Part Grouping Explanation

Substitution between the main part (2-643814-0) and the identified equivalent (5-643814-0) is based on strict alignment of the following critical parameters:

Critical Alignment Parameters:

• Connector Type: Both are Receptacle connectors
• Number of Positions: Both feature 20 positions
• Pitch: Both maintain 0.100" (2.54mm) spacing
• Contact Type: Both utilize Female Socket contacts
• Cable Termination: Both employ IDC termination method
• Wire Gauge: Both support 24 AWG wire
• Number of Rows: Both are single-row configurations
• Mounting Type: Both are Free Hanging (In-Line), Right Angle
• Fastening Type: Both use Locking Ramp fastening
• Series: Both belong to MTA-100 series
• Features: Both are Closed End designs

Differentiating Parameters:

• Contact Finish: 2-643814-0 uses Tin-Lead; 5-643814-0 uses Tin
• Packaging: 2-643814-0 packaging not specified; 5-643814-0 is Bulk packaged
• RoHS Status: 2-643814-0 is Not applicable; 5-643814-0 is ROHS3 Compliant

The contact finish difference (Tin-Lead versus Tin) and RoHS compliance status represent the primary distinctions between these parts. Both finishes maintain the same thickness specification of 80.0µin (2.03µm), ensuring equivalent electrical and mechanical performance in IDC rectangular connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-643814-0 and 5-643814-0 are active production parts from TE Connectivity AMP Connectors and are functionally equivalent for rectangular connector applications requiring 20-position IDC termination at 24 AWG.

Selection Criteria Based on Compliance and Certification:

The 5-643814-0 substitute part carries ROHS3 compliance certification, making it the appropriate selection for applications subject to Restriction of Hazardous Substances regulations. The 2-643814-0 main part lists RoHS status as Not applicable, indicating it may contain lead-based materials in the tin-lead contact finish.

The contact finish difference between tin-lead (2-643814-0) and tin (5-643814-0) reflects the primary material distinction. Both finishes maintain identical thickness specifications and are suitable for IDC rectangular connector applications. The tin finish of the 5-643814-0 aligns with modern environmental and regulatory standards.

Both parts maintain identical electrical and mechanical specifications across all critical parameters: 20 positions, 0.100" pitch, single-row configuration, locking ramp fastening, and closed-end design. Inventory availability differs, with 5-643814-0 showing 1443 pieces in stock compared to 896 pieces for 2-643814-0.

Frequently Asked Questions (FAQ)

Q: Can 5-643814-0 be used as a direct replacement for 2-643814-0?

A: Yes. Both parts are functionally equivalent rectangular receptacle connectors within the MTA-100 series. They share identical specifications for connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism. The primary difference is the contact finish material (tin versus tin-lead) and RoHS compliance status.

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

A: The 2-643814-0 features a tin-lead contact finish, while the 5-643814-0 uses tin. Both maintain the same finish thickness of 80.0µin (2.03µm). The tin finish in the 5-643814-0 is lead-free and complies with ROHS3 regulations, making it suitable for applications with environmental or regulatory restrictions on hazardous substances.

Q: Are these parts compatible with the same mating connectors?

A: Yes. Both parts are 20-position receptacle connectors with 0.100" pitch spacing within the MTA-100 series. They are mechanically and electrically compatible with identical mating plug connectors designed for this series and pitch specification.

Q: What does IDC termination mean for these connectors?

A: IDC (Insulation Displacement Contact) termination allows direct connection of discrete or ribbon cable without stripping insulation. The cable is inserted into the connector, and the IDC contacts pierce the insulation to establish electrical connection. Both parts support this termination method for 24 AWG wire.

Q: How does packaging affect the selection between these parts?

A: The 2-643814-0 packaging specification is not provided in the technical data. The 5-643814-0 is supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and handling considerations.

Q: What is the Moisture Sensitivity Level (MSL) rating for these connectors?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard environmental conditions without special moisture control measures.

Q: Are both parts currently available for procurement?

A: Yes. Both parts maintain Active product status. The 2-643814-0 has 896 pieces in new original inventory, while the 5-643814-0 has 1443 pieces available.
