Key Parameters

Substitute Part Grouping Explanation

Substitution of the MT228024 is based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the main part specifications:

Critical Matching Parameters:

• Coil voltage: 24VAC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 10A minimum (exact match required)
• Switching voltage: 400VAC maximum (exact match or higher acceptable)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In, 8 Pin (Octal) (exact match required)
• Coil type: Non Latching (exact match required)
• Contact material: Silver Nickel (AgNi) (exact match required)

The substitute part 60.12.8.024.0050 from Finder Relays, Inc. meets all critical electrical and mechanical parameters, enabling direct functional replacement in applications requiring MT228024 specifications.

Parameter Comparison

Engineering Selection Recommendations

The 60.12.8.024.0050 from Finder Relays, Inc. is a direct functional equivalent to the obsolete MT228024. Both parts are ROHS3 compliant and share identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage.

The substitute part offers the following advantages:

• Active Product Status: The 60.12.8.024.0050 is in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Certifications: The Finder relay carries multiple approval agencies including CCC, CE, CSA, cURus, EAC, RINA, UKCA, and VDE, providing broader regulatory acceptance.
• Improved Performance Characteristics: The substitute exhibits faster operate and release times (11 ms and 4 ms respectively versus 15 ms and 10 ms), and operates across a wider temperature range (-40°C to 70°C versus -40°C to 50°C).
• Regulatory Compliance: Both parts meet ROHS3 requirements and share the same ECCN and HTSUS classifications.

The substitute part is suitable for direct replacement in applications where the MT228024 was previously specified.

Frequently Asked Questions (FAQ)

Q: Can the 60.12.8.024.0050 be used as a direct replacement for the MT228024?

A: Yes. Both relays share identical coil voltage (24VAC), contact form (DPDT), current rating (10A), switching voltage (400VAC maximum), mounting type (socketable), termination style (8-pin octal), and contact material (Silver Nickel). The substitute part meets all critical electrical and mechanical requirements for direct substitution.

Q: What are the differences between these two relays?

A: The primary differences are product status and performance characteristics. The MT228024 is obsolete, while the 60.12.8.024.0050 is in active production. The Finder relay operates faster (11 ms operate time versus 15 ms) and releases faster (4 ms versus 10 ms). The Finder relay also operates across a wider temperature range (-40°C to 70°C versus -40°C to 50°C) and has lower coil resistance (74 Ohms versus 86 Ohms). The must-release voltage is lower for the Finder relay (4.8 VAC versus 9.6 VAC).

Q: Are both relays RoHS compliant?

A: Yes. Both the MT228024 and 60.12.8.024.0050 are ROHS3 compliant.

Q: What certifications does the substitute part carry?

A: The 60.12.8.024.0050 carries certifications from CCC, CE, CSA, cURus, EAC, RINA, UKCA, and VDE. The MT228024 specifications provided do not list specific approval agencies.

Q: Will the substitute relay fit in existing sockets designed for the MT228024?

A: Yes. Both relays use identical 8-pin octal plug-in termination and socketable mounting, ensuring mechanical compatibility with existing relay bases and sockets.

Q: Is the faster switching time of the substitute relay a concern?

A: The faster operate and release times of the 60.12.8.024.0050 (11 ms and 4 ms respectively) are improvements over the MT228024 (15 ms and 10 ms). These faster response times do not create compatibility issues and may provide performance benefits in timing-sensitive applications.

Q: What is the coil current requirement for the substitute relay?

A: The 60.12.8.024.0050 has a coil current of 90 mA at 24VAC, corresponding to its 74-ohm coil resistance.
