Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2Z-02 DC12 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Coil voltage: 12VDC
• Contact configuration: DPDT (2 Form C)
• Contact rating: 5A minimum
• Coil current: 75 mA
• Coil resistance: 160 Ohms
• Non-latching coil type

Substitutes are grouped into two categories:

Parametric Equivalent (MY2-02-DC12): Identical electrical specifications and through-hole mounting with PC pin termination. This part maintains full compatibility with the original design without modification.

Similar Substitute (KHAU-11D12-12): Meets core electrical requirements (12VDC coil, DPDT configuration, 5A rating, 75mA coil current, 160 Ohms resistance) but differs in mounting type (socketable vs. through-hole) and termination style (plug-in vs. PC pin). This substitute requires mechanical redesign of the mounting interface.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Redesign): The MY2-02-DC12 is the recommended substitute for the obsolete MY2Z-02 DC12. Both parts are manufactured by Omron Automation and Safety and share identical electrical specifications, mounting type (through-hole), and termination style (PC pin). The MY2-02-DC12 maintains active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

For Applications Permitting Mechanical Redesign: The KHAU-11D12-12 from TE Connectivity Potter & Brumfield Relays meets all core electrical requirements and is actively manufactured. However, this substitute requires PCB redesign due to socketable mounting and plug-in termination. The KHAU-11D12-12 operates within a narrower temperature range (-45°C to 70°C versus -55°C to 70°C) and uses silver cadmium oxide contacts instead of silver. Additionally, this part is RoHS non-compliant and REACH-affected, which may conflict with regulatory requirements in certain applications.

Frequently Asked Questions (FAQ)

Q: Can MY2-02-DC12 be used as a direct replacement for MY2Z-02 DC12? A: Yes. The MY2-02-DC12 is a parametric equivalent with identical coil voltage (12VDC), contact configuration (DPDT), current rating (5A), coil current (75mA), and coil resistance (160 Ohms). Both parts use through-hole mounting with PC pin termination, requiring no PCB modifications.

Q: What are the key differences between MY2-02-DC12 and KHAU-11D12-12? A: The primary differences are mounting type (through-hole vs. socketable), termination style (PC pin vs. plug-in), operating temperature range (-55°C to 70°C vs. -45°C to 70°C), contact material (silver vs. silver cadmium oxide), and regulatory compliance (RoHS compliant vs. RoHS non-compliant). Electrical specifications for coil voltage, contact form, and current rating are identical.

Q: Is the KHAU-11D12-12 suitable for applications requiring RoHS compliance? A: No. The KHAU-11D12-12 is RoHS non-compliant and REACH-affected. Applications with RoHS compliance requirements must use the MY2-02-DC12.

Q: What is the temperature operating range difference between substitutes? A: The MY2Z-02 DC12 and MY2-02-DC12 both operate from -55°C to 70°C. The KHAU-11D12-12 operates from -45°C to 70°C, providing a narrower low-temperature range. Applications requiring operation below -45°C must use the Omron parts.

Q: Can KHAU-11D12-12 be used without PCB modifications? A: No. The KHAU-11D12-12 requires PCB redesign due to socketable mounting and plug-in termination, whereas the original MY2Z-02 DC12 uses through-hole mounting with PC pins.

Q: What is the coil current requirement for all three parts? A: All three parts require 75 mA coil current with 160 Ohms coil resistance at 12VDC, ensuring identical drive circuit requirements.
