Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2Z AC24 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 24VAC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 5 A
• Switching voltage capability: 250VAC, 125VDC maximum
• Coil current draw: 46 mA
• Mounting type: Socketable
• Termination style: Plug In
• Operating temperature range: -55°C ~ 70°C
• Contact material: Silver (Ag)
• Coil resistance: 180 Ohms
• Timing characteristics: 20 ms operate and release times

The MY2 AC24 (S) variant meets all these parameters and is classified as a parametric equivalent. Both parts belong to the Omron MY series and share identical electrical and mechanical specifications, enabling direct substitution in socketable relay applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MY2Z AC24 and MY2 AC24 (S) are active production parts from Omron Automation and Safety, ensuring long-term availability and supply chain stability. Both parts carry RoHS compliance certification, meeting environmental and regulatory requirements for industrial applications.

Selection between these parts should be based on inventory availability and lead time requirements. The MY2Z AC24 has 755 units in stock, while the MY2 AC24 (S) has 1351 units available. For applications requiring immediate procurement, the MY2 AC24 (S) offers greater stock depth. Both parts are electrically and mechanically identical, with no functional differentiation in socketable relay applications.

Frequently Asked Questions (FAQ)

Q: Can the MY2 AC24 (S) directly replace the MY2Z AC24 in existing installations?

A: Yes. Both parts are parametric equivalents with identical coil voltage, contact configuration, current rating, switching voltage capability, and timing characteristics. Direct substitution is supported without circuit modification.

Q: What determines whether a relay can substitute for the MY2Z AC24?

A: Substitution requires matching of coil voltage (24VAC), contact form (DPDT), current rating (5A), switching voltage limits (250VAC/125VDC), coil current (46 mA), mounting type (socketable), and termination style (plug in). All timing and temperature specifications must also align.

Q: Are there differences in packaging or handling between these parts?

A: Both parts are supplied in bulk packaging. No differences in moisture sensitivity level (MSL 1 - Unlimited) or handling requirements exist between the MY2Z AC24 and MY2 AC24 (S).

Q: What is the significance of the "(S)" designation in MY2 AC24 (S)?

A: The "(S)" designation indicates a variant within the MY2 AC24 product line. Despite this notation, the part maintains full parametric equivalence with the MY2Z AC24 across all specified electrical and mechanical parameters.

Q: Can these relays be used interchangeably in 24VAC control circuits?

A: Yes. Both relays are rated for 24VAC coil operation with identical must-operate (19.2 VAC) and must-release (7.2 VAC) voltage thresholds, enabling interchangeable use in 24VAC control circuits.
