ADJ55012 Equivalent & Substitute Parts

Part Overview

The ADJ55012 is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VDC coil. This through-hole mounted relay is designed for applications requiring 10A switching capacity at up to 250VAC. The part is currently active in production with 990 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications allow direct replacement in circuit applications while maintaining functional performance and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADJ55012 is determined by the following critical parameters:

• Coil Voltage: Must be 12VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be DPDT (2 Form C) to maintain switching topology
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Coil Type: Must be Non Latching for equivalent operational behavior
• Termination Style: Must be PC Pin for direct pin-to-pin replacement

The RT424012 from TE Connectivity Potter & Brumfield Relays meets these core substitution criteria. While the RT424012 exhibits lower contact current rating (8A versus 10A) and different switching voltage specification (400VAC versus 250VAC), it maintains functional equivalence for applications within its rated parameters and shares identical coil voltage, contact form, mounting type, and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ADJ55012 and RT424012 maintain active product status with current manufacturing support. The ADJ55012 carries CQC, cURus, and VDE approvals. The RT424012 carries ROHS3 compliance and REACH Unaffected status, indicating alignment with current environmental regulations.

Selection between these parts should be based on application-specific current requirements. The ADJ55012 is suitable for applications requiring the full 10A contact rating. The RT424012 is suitable for applications with maximum switching current of 8A or less. Both parts operate within the 12VDC coil voltage specification and share identical contact form and mounting characteristics, making them functionally interchangeable within their respective current ratings.

The RT424012 exhibits faster switching response times (8ms operate, 6ms release versus 20ms for both parameters on the ADJ55012) and operates across a wider temperature range (-40°C to 85°C versus -40°C to 70°C). The ADJ55012 supports higher maximum switching voltage (250VAC versus 400VAC on the RT424012).

Frequently Asked Questions (FAQ)

Q: Can the RT424012 directly replace the ADJ55012 in all applications?

A: Direct replacement is possible only in applications where the switching current does not exceed 8A. The RT424012 is rated for 8A maximum continuous current, while the ADJ55012 is rated for 10A. If the application requires switching currents between 8A and 10A, the ADJ55012 must be used.

Q: What are the key differences between these two relays?

A: The primary differences are contact current rating (10A versus 8A), switching voltage specification (250VAC versus 400VAC), coil current draw (20.8mA versus 33.3mA), and switching response times. Both share identical coil voltage (12VDC), contact form (DPDT), mounting type (Through Hole), and termination style (PC Pin).

Q: Are both parts RoHS compliant?

A: Yes. The ADJ55012 is RoHS Compliant. The RT424012 is ROHS3 Compliant, representing a more recent compliance standard.

Q: Do these relays have the same physical footprint?

A: Both relays feature Through Hole mounting with PC Pin termination style, ensuring PCB compatibility. However, physical dimensions are not provided in the specification data. Mechanical drawings should be consulted to confirm identical footprint before substitution.

Q: What is the operating voltage range for each relay?

A: The ADJ55012 must operate at a minimum of 9VDC and release at 1.2VDC or below. The RT424012 must operate at a minimum of 8.4VDC and release at 1.2VDC or below. Both are designed for 12VDC nominal coil voltage.

Q: Can these relays be used in high-temperature applications?

A: The ADJ55012 operates from -40°C to 70°C. The RT424012 operates from -40°C to 85°C, providing a wider temperature range suitable for higher ambient temperature environments.
