Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MY2IN1 DC12 (S) are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Coil voltage: 12VDC
• Contact form: DPDT (2 Form C)
• Mounting type: Socketable
• Termination style: Plug In
• Coil type: Non Latching

Secondary Compatibility Considerations:

• Contact rating (current capacity)
• Switching voltage capability
• Operating temperature range
• Coil current and resistance
• Operate and release timing

The identified substitute parts maintain the core electrical and mechanical characteristics required for direct replacement in standard general purpose relay applications. Variations in contact rating, switching voltage, and timing parameters are noted to enable informed selection based on specific application requirements.

Engineering Selection Recommendations

MY2IN1 DC12 (S) - Primary Selection

The MY2IN1 DC12 (S) is the specified part with active production status and RoHS compliance. This part is recommended for new designs and applications requiring full compliance with current environmental regulations.

KHAU-11D12-12 - Equivalent Substitute

The KHAU-11D12-12 provides electrical and mechanical equivalence with identical contact rating (5A), coil voltage (12VDC), coil current (75mA), and coil resistance (160 Ohms). This part maintains socketable mounting and plug-in termination. However, this part is RoHS non-compliant and REACH affected, making it unsuitable for applications with environmental compliance requirements. The operating temperature range is narrower (-45°C to 70°C versus -55°C to 70°C). Faster switching times (13ms operate, 6ms release) may be advantageous in time-critical applications.

PT270012 - Higher Current Capacity Substitute

The PT270012 is suitable for applications where higher contact current capacity (12A versus 5A) is required while maintaining 12VDC coil voltage and DPDT contact form. This part offers superior switching voltage capability (400VAC maximum) and is ROHS3 compliant. The coil current is lower (62.5mA versus 75mA), and switching times are faster (15ms operate, 10ms release). The operating temperature range is narrower (-40°C to 70°C). Termination includes both plug-in and quick connect options. This part is suitable for applications requiring higher current switching capacity with maintained compliance status.

Frequently Asked Questions (FAQ)

Q: Can KHAU-11D12-12 be used as a direct replacement for MY2IN1 DC12 (S)?

A: The KHAU-11D12-12 provides electrical and mechanical compatibility with identical contact rating, coil voltage, and resistance. However, it is RoHS non-compliant and REACH affected. Direct replacement is possible only in applications without environmental compliance requirements.

Q: What is the primary difference between MY2IN1 DC12 (S) and PT270012?

A: The PT270012 has a higher contact current rating (12A versus 5A) and superior switching voltage capability (400VAC versus 250VAC). The PT270012 is suitable for applications requiring higher current switching capacity. Both maintain 12VDC coil voltage and DPDT contact form.

Q: Are all three relays socketable?

A: Yes, all three parts feature socketable mounting type with plug-in termination, enabling installation in standard relay sockets.

Q: What are the coil resistance differences among these parts?

A: MY2IN1 DC12 (S) and KHAU-11D12-12 both have 160 Ohm coil resistance. PT270012 has 192 Ohm coil resistance. These differences reflect design variations between manufacturers.

Q: Which part has the fastest switching response?

A: KHAU-11D12-12 has the fastest operate time (13ms) and release time (6ms). MY2IN1 DC12 (S) has 20ms for both operate and release. PT270012 has 15ms operate and 10ms release times.

Q: Are there temperature range limitations I should consider?

A: MY2IN1 DC12 (S) operates from -55°C to 70°C. KHAU-11D12-12 operates from -45°C to 70°C. PT270012 operates from -40°C to 70°C. Applications requiring operation below -45°C require the MY2IN1 DC12 (S).

Q: What compliance certifications apply to each part?

A: MY2IN1 DC12 (S) is RoHS compliant. KHAU-11D12-12 is RoHS non-compliant and REACH affected. PT270012 is ROHS3 compliant and REACH unaffected. Applications with environmental compliance requirements should use MY2IN1 DC12 (S) or PT270012.
