TE Connectivity AMP Connectors 4-644457-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-644457-4 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 14 positions at 0.100" (2.54mm) pitch and is part of the MTA-100 series. The part is currently active in production and widely used in general-purpose board-to-cable/wire interconnect applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative connector characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-644457-4 is determined by the following critical parameters that must align across connector families:

Primary Matching Criteria:

• Number of Positions: 14
• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder

Secondary Compatibility Factors:

• Operating Temperature Range (minimum -40°C acceptable for most applications)
• Voltage Rating (250VAC or unspecified acceptable)
• Material Flammability Rating: UL94 V-0
• Contact Material: Copper Alloy
• Contact Finish: Tin or Gold (both acceptable for general-purpose applications)

The 3M 929550-01-14-EU meets all primary matching criteria and secondary compatibility factors, establishing it as a valid substitute. Differences in contact finish thickness, insulation material composition, and specific contact dimensions do not preclude substitution for standard board-to-cable interconnect applications where mechanical fit and electrical continuity are the governing requirements.

Engineering Selection Recommendations

TE Connectivity 4-644457-4 (Primary Selection)

Select this part when:

• Extended low-temperature operation below -40°C is required
• Tin contact finish is specified for compatibility with existing solder joint processes
• ROHS3 compliance documentation is required for supply chain traceability
• Unlimited moisture sensitivity level is advantageous for storage and handling

3M 929550-01-14-EU (Substitute Selection)

Select this part when:

• TE Connectivity 4-644457-4 is unavailable from inventory or supply chain
• Gold contact finish is preferred for enhanced corrosion resistance in high-humidity environments
• Breakaway header functionality provides design flexibility for modular applications
• Operating temperature range of -40°C to 105°C satisfies application requirements
• Current rating specification of 2.5A per contact meets circuit requirements

Both parts carry UL94 V-0 flammability certification and are manufactured from copper alloy contact materials, ensuring electrical performance consistency across substitution.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929550-01-14-EU directly replace the TE Connectivity 4-644457-4 in existing PCB designs?

A: Yes. Both connectors share identical 14-position configuration, 0.100" (2.54mm) pitch, through-hole right-angle mounting, and solder termination. PCB footprints are compatible. The primary difference is contact finish (gold versus tin) and insulation material composition, which do not affect mechanical fit or electrical continuity in standard board-to-cable applications.

Q: What is the significance of the contact finish difference between tin and gold?

A: Tin contact finish provides cost-effective performance for general-purpose applications with standard solder joint processes. Gold contact finish offers enhanced corrosion resistance and is preferred in high-humidity, high-reliability, or long-term storage environments. Both finishes are acceptable for the same mating interface.

Q: Does the operating temperature range difference affect substitution suitability?

A: The TE Connectivity part operates from -55°C to 105°C, while the 3M substitute operates from -40°C to 105°C. For applications requiring operation below -40°C, the TE Connectivity part is required. For applications within -40°C to 105°C range, both parts are suitable.

Q: What does "Breakaway" header designation mean for the 3M part?

A: Breakaway headers allow individual positions to be separated or removed after assembly, providing design flexibility for modular or reconfigurable applications. This feature does not affect compatibility with standard mating connectors or cables.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry UL94 V-0 flammability certification. The TE Connectivity part specifies ROHS3 compliance; the 3M part does not provide this specification in the available data. For applications requiring documented ROHS3 compliance, the TE Connectivity part is the appropriate selection.

Q: What is the current rating specification, and how does it affect part selection?

A: The TE Connectivity part specifies current rating as "Varies by Wire Gauge," indicating current capacity depends on the mating cable or wire gauge. The 3M part specifies 2.5A per contact. For applications requiring explicit current rating documentation, the 3M part provides this specification. Both parts are suitable for general-purpose applications where wire gauge determines current capacity.

Q: Can these connectors be used interchangeably in production assembly?

A: Yes, for applications where the operating temperature range of -40°C to 105°C is acceptable and contact finish specifications do not impose constraints. Assembly processes remain identical due to matching solder termination and through-hole mounting characteristics.
