Parameter Comparison

Engineering Selection Recommendations

The 4-641126-4 is a direct functional equivalent to the 1-641126-4 across all critical electrical, mechanical, and environmental parameters. The primary distinction is product status: the 1-641126-4 is classified as obsolete, while the 4-641126-4 maintains active status with TE Connectivity AMP Connectors.

Both parts comply with RoHS requirements, with the main part designated ROHS3 Compliant and the substitute designated RoHS Compliant. Both achieve UL94 V-0 material flammability rating and operate across the identical temperature range of -55°C to 105°C.

The 4-641126-4 is supplied in bulk packaging and demonstrates higher current inventory levels (748 pieces) compared to the main part (647 pieces), indicating superior long-term availability for production planning and field service applications.

For new designs, production transitions, and component replenishment, the 4-641126-4 is the appropriate selection due to its active product status and sustained manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 4-641126-4 be used as a direct replacement for the 1-641126-4 in existing designs?

A: Yes. The 4-641126-4 maintains identical electrical specifications (14 positions, 0.100" pitch, 250VAC rating), mechanical configuration (through-hole mounting, shrouded header, solder termination), and environmental performance (-55°C to 105°C operating range). All contact dimensions, materials, and finishes are equivalent.

Q: What is the significance of the different part number prefix (1- versus 4-)?

A: The prefix variation indicates different manufacturing or packaging designations within the TE Connectivity AMP Connectors product line. Both parts belong to the MTA-100 series and share identical functional specifications. The 4-641126-4 is supplied in bulk packaging.

Q: Are there compliance differences between the two parts?

A: Both parts comply with RoHS requirements and achieve UL94 V-0 material flammability rating. The main part is designated ROHS3 Compliant, while the substitute is designated RoHS Compliant. Both maintain Moisture Sensitivity Level 1 (Unlimited) classification.

Q: Why should the 4-641126-4 be selected over the 1-641126-4?

A: The 1-641126-4 is classified as obsolete, indicating discontinued production and limited long-term availability. The 4-641126-4 maintains active product status with TE Connectivity, ensuring sustained supply chain support, technical documentation access, and manufacturing consistency for current and future applications.

Q: Are the contact finishes identical between the two parts?

A: Yes. Both parts feature gold-plated mating contacts (15.0µin/0.38µm thickness) and tin-plated posts (150.0µin/3.81µm thickness) on copper alloy contact material.

Q: What is the packaging difference between these parts?

A: The 1-641126-4 packaging is not specified in available documentation. The 4-641126-4 is supplied in bulk packaging, which is standard for high-volume production and field service inventory applications.

Q: Can these connectors be used interchangeably in mating applications?

A: Yes. Both parts are shrouded single-wall headers with friction lock fastening, designed for board-to-cable/wire interconnection. They accept identical mating connectors and maintain equivalent electrical and mechanical performance in all general-purpose applications.
