Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers within the MTA-100 series is determined by strict equivalence across the following parameters:

• Connector Type and Contact Configuration: Header with male pin contacts
• Position Count and Pitch: 10 positions at 0.100" (2.54mm) mating pitch
• Mounting and Termination: Through-hole solder termination with friction lock fastening
• Shrouding Design: Shrouded with 1 wall configuration
• Electrical Ratings: 250VAC voltage rating and temperature range of -55°C to 105°C
• Material and Compliance: Copper alloy contacts with thermoplastic insulation, UL94 V-0 flammability rating, and RoHS compliance

The substitute part 4-641126-0 maintains identical electrical and mechanical specifications across all critical parameters. Substitution is valid based on complete parameter alignment within the MTA-100 series classification.

Parameter Comparison

Engineering Selection Recommendations

Both 1-641126-0 and 4-641126-0 are active products manufactured by TE Connectivity AMP Connectors within the MTA-100 series. Both parts maintain full RoHS compliance and UL94 V-0 flammability certification. The substitute part 4-641126-0 carries ROHS3 compliance status, indicating alignment with the most current regulatory requirements.

Selection between these parts is based on availability and procurement requirements. The 4-641126-0 variant currently maintains higher inventory levels (5904 pieces) compared to 1-641126-0 (1129 pieces), making it suitable for applications requiring extended supply assurance. Both parts are electrically and mechanically interchangeable for all board-to-cable/wire applications operating within the specified temperature and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Are 1-641126-0 and 4-641126-0 electrically interchangeable?

A: Yes. Both parts operate at identical voltage ratings (250VAC), current capacity (varies by wire gauge), and temperature ranges (-55°C to 105°C). The electrical performance is equivalent across all specified parameters.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the most current regulatory iteration. Both parts meet hazardous substance restrictions and are suitable for applications requiring RoHS compliance.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. Both parts share identical mechanical dimensions, mounting specifications (through-hole solder termination), shrouding configuration (shrouded 1 wall), and contact geometry (square male pins at 0.100" pitch). PCB footprints and assembly processes require no modification.

Q: What is the significance of the contact finish specifications?

A: The mating contacts feature gold plating (15.0µin thickness) for corrosion resistance and reliable signal transmission. The post contacts feature tin plating (150.0µin thickness) for solder joint integrity. Both parts maintain identical finish specifications.

Q: Are there any packaging or inventory considerations when selecting between these parts?

A: Both parts are supplied in bulk packaging. The 4-641126-0 variant maintains significantly higher inventory availability (5904 pieces versus 1129 pieces), which may influence procurement timelines and lead times for high-volume applications.

Q: What applications are these connectors suitable for?

A: Both parts are classified for general-purpose applications. The board-to-cable/wire configuration, friction lock fastening, and through-hole solder termination make them suitable for standard interconnect applications requiring reliable mechanical and electrical connections across the -55°C to 105°C operating range.
