TE Connectivity AMP Connectors 641212-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641212-4 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 4-position configuration with 0.100" (2.54mm) pitch spacing, suitable for board-to-cable/wire interconnections in general-purpose applications. The part maintains active product status with full inventory availability. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the MTA-100 series connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 641212-4 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact length specifications (Mating: 0.295" / 7.49mm; Post: 0.140" / 3.56mm)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)
• Series designation (MTA-100)
• Termination method (Solder)
• Contact material (Copper Alloy)
• Insulation material (Thermoplastic)

Parts meeting these criteria are classified as direct substitutes. Variations in packaging configuration, inventory status, or minor contact finish specifications do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 641212-4 and 3-641212-4 are active products manufactured by TE Connectivity AMP Connectors within the MTA-100 series. Selection between these parts is based on the following criteria:

641212-4: This part is suitable for applications requiring standard packaging configurations. It maintains RoHS compliance and carries a Moisture Sensitivity Level of 1, indicating unlimited shelf life under normal storage conditions.

3-641212-4: This substitute part is functionally equivalent and offers bulk packaging availability. It maintains ROHS3 compliance, which represents an updated regulatory status. The higher inventory level (5282 pieces versus 1121 pieces) provides extended availability for high-volume production requirements.

Both parts satisfy identical electrical and mechanical specifications, including voltage rating (250VAC), operating temperature range (-55°C ~ 105°C), and contact configuration. The choice between these parts depends on packaging requirements, inventory availability, and supply chain considerations rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 641212-4 and 3-641212-4 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including voltage rating (250VAC), current rating (varies by wire gauge), operating temperature range (-55°C ~ 105°C), and contact material composition (Copper Alloy with gold mating finish).

Q: What is the difference between these two part numbers?

A: The primary differences are packaging configuration and regulatory compliance status. The 641212-4 uses standard packaging, while the 3-641212-4 uses bulk packaging. The 3-641212-4 carries ROHS3 compliance status compared to RoHS compliance for the 641212-4. Both parts are mechanically and electrically identical.

Q: Can I use the 3-641212-4 as a direct replacement for the 641212-4 in existing designs?

A: Yes. The 3-641212-4 is a direct substitute with identical mechanical dimensions, contact configurations, and electrical ratings. No design modifications are required.

Q: What are the critical parameters that define substitutability for this connector?

A: Substitutability is determined by: connector type (Header), contact type (Male Pin), number of positions (4), pitch spacing (0.100" / 2.54mm), mounting type (Through Hole, Right Angle), contact lengths (Mating: 0.295" / 7.49mm; Post: 0.140" / 3.56mm), voltage rating (250VAC), operating temperature range (-55°C ~ 105°C), and series designation (MTA-100).

Q: Are there any compatibility issues with different packaging types?

A: No. Packaging differences (standard versus bulk) do not affect connector functionality or compatibility. The internal connector specifications and performance characteristics remain identical regardless of packaging configuration.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life under normal storage conditions. No special moisture control measures are required during storage or handling.

Q: Do these connectors require any special handling or storage conditions?

A: Both parts maintain MSL 1 status, which means they do not require controlled humidity storage. Standard industrial storage conditions are appropriate for these components.
