The MTG306D is an active product within the same manufacturer series, providing direct functional replacement capability for the obsolete 2-1571926-7.

Parameter Comparison

Engineering Selection Recommendations

The MTG306D is the direct substitute for the obsolete 2-1571926-7 based on complete electrical and mechanical parameter equivalence. Selection of MTG306D is supported by the following factors:

Product Status: MTG306D maintains active product status with TE Connectivity ALCOSWITCH, ensuring ongoing availability and supply chain continuity.

Regulatory Compliance: MTG306D is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The part is subject to REACH regulations, reflecting compliance with current European chemical safety requirements.

Functional Equivalence: All critical electrical parameters (circuit configuration, current ratings, voltage ratings, switch function) and mechanical parameters (mounting, termination, actuator specifications, operating temperature range) are identical between the main part and substitute.

Series Continuity: Both parts belong to the MTG Green series, maintaining design consistency and interchangeability within the product line.

Frequently Asked Questions (FAQ)

Q: Can MTG306D be used as a direct replacement for 2-1571926-7 in existing designs?

A: Yes. MTG306D provides direct functional and mechanical replacement. All electrical ratings (6A AC at 125V, 4A DC at 28V), circuit configuration (3PDT On-On), mounting type (panel mount), termination style (solder lug), and actuator specifications are identical.

Q: What is the difference between 2-1571926-7 and MTG306D?

A: The primary difference is product status: 2-1571926-7 is obsolete while MTG306D is active. MTG306D also includes ROHS3 compliance certification and is subject to REACH regulations. Actuator material differs (copper alloy chrome plated versus brass nickel plated), but electrical and mechanical performance parameters remain equivalent.

Q: Are there any panel cutout or mechanical installation differences?

A: Both parts share identical bushing thread specifications (15/32-32) and actuator dimensions (11.50mm length, standard round type). Panel cutout dimensions are not specified for MTG306D but the identical bushing thread ensures compatible panel mounting.

Q: What is the packaging difference?

A: 2-1571926-7 is supplied in standard packaging while MTG306D is supplied in bulk packaging. This does not affect component functionality or performance.

Q: Is MTG306D suitable for applications requiring ROHS3 compliance?

A: Yes. MTG306D is ROHS3 compliant, making it suitable for applications with environmental and hazardous substance restrictions.

Q: Are there electrical life cycle differences between the parts?

A: Electrical life specification is provided for 2-1571926-7 (80,000 cycles) but not specified for MTG306D. Both parts are rated for identical electrical performance parameters and operating conditions.
