Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1571926-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 6A AC / 4A DC minimum
• Voltage rating: 125V AC / 28V DC minimum
• Electrical life: 80,000 cycles minimum

Mechanical Parameters (Non-Negotiable):

• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout diameter: 11.94mm (Circular)
• Bushing thread: 15/32-32
• Actuator type: Standard Round
• Actuator length: 11.50mm

Environmental Parameters:

• Operating temperature range: -20°C to 80°C
• Features: Epoxy sealed terminals

The substitute part MTG106D meets all specified electrical and mechanical parameters and is manufactured by the same supplier, ensuring design compatibility and functional equivalence.

Engineering Selection Recommendations

The MTG106D serves as a direct functional and mechanical equivalent to the obsolete 1571926-3. Selection of MTG106D is based on the following engineering factors:

Product Status Alignment: The 1571926-3 is classified as obsolete, while MTG106D maintains active product status with TE Connectivity ALCOSWITCH Switches. This transition ensures continued availability and manufacturer support for new production builds and field replacements.

Electrical and Mechanical Equivalence: All critical electrical parameters (current ratings, voltage ratings, circuit configuration, and electrical life) are identical between the two parts. Mechanical parameters including mounting type, panel cutout dimensions, bushing thread specification, and actuator geometry are fully matched, ensuring direct substitution without design modification.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, maintaining consistent export and tariff treatment. The substitute part is available in bulk packaging, supporting production-scale deployment.

Inventory Availability: MTG106D is available with 2035 pieces in stock, providing immediate procurement capability compared to the limited remaining inventory of the obsolete 1571926-3.

Frequently Asked Questions (FAQ)

Q: Can MTG106D be used as a direct replacement for 1571926-3 without circuit modification?

A: Yes. MTG106D is electrically and mechanically equivalent to 1571926-3 across all specified parameters. No circuit modification, panel cutout redesign, or termination rework is required. The part is a direct substitution.

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts are rated for 6A at 125V AC and 4A at 28V DC, with identical SPDT configuration, On-On function, and 80,000-cycle electrical life. Operating temperature range and actuator specifications are identical.

Q: What is the difference in product status between 1571926-3 and MTG106D?
