ADQM16024 Equivalent & Substitute Parts

Part Overview

The ADQM16024 is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 24VDC coil. This through-hole mounted relay is rated for 60A continuous current operation at 250VAC maximum switching voltage, with a maximum switching load of 15000VA. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADQM16024 is determined by the following critical parameters:

• Coil voltage must be 24VDC to ensure direct compatibility with existing control circuits
• Contact form must remain SPST-NO (1 Form A) to maintain identical switching logic
• Contact current rating must meet or exceed 60A to handle the same load requirements
• Maximum switching voltage must be at least 250VAC to support the same application voltage levels
• Coil type must be latching, single coil to preserve operational characteristics
• Operating temperature range must encompass the required -40°C to 70°C minimum specification

The ADZS12124 qualifies as a substitute based on these parameters. While it features a different mounting type (chassis mount versus through hole) and termination style (screw terminal versus PC pin), these are mechanical considerations that can be accommodated through appropriate board redesign or adapter solutions. The ADZS12124 exceeds the electrical performance requirements of the ADQM16024 across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The ADZS12124 is the identified substitute for the obsolete ADQM16024. Selection of this substitute is supported by the following factors:

The ADZS12124 maintains identical electrical specifications for coil voltage (24VDC), contact form (SPST-NO), and switching timing (20 ms operate/release), ensuring functional equivalence in control circuit applications. The substitute exceeds the original part's current rating (90A versus 60A), maximum switching voltage (276VAC versus 250VAC), and maximum switching load (24840VA versus 15000VA), providing enhanced performance margin for the same application requirements.

Both parts are manufactured by Panasonic Electric Works and comply with RoHS standards. The ADZS12124 meets the newer ROHS3 specification, indicating compliance with current environmental regulations. The extended operating temperature range of the ADZS12124 (-40°C to 85°C versus -40°C to 70°C) provides additional thermal margin.

The primary design consideration is the mechanical interface change from through-hole PC pin termination to chassis mount screw terminal configuration. This substitution requires board-level redesign or the implementation of appropriate mechanical and electrical adapters to accommodate the different mounting and termination styles.

Frequently Asked Questions (FAQ)

Q: Can the ADZS12124 directly replace the ADQM16024 without any modifications?

A: Electrical substitution is valid; however, mechanical interface modification is required. The ADQM16024 uses through-hole PC pin termination, while the ADZS12124 uses chassis mount screw terminals. Board redesign or adapter solutions must be implemented to accommodate this difference.

Q: Are there any coil voltage compatibility concerns?

A: No. Both relays operate on 24VDC coils and are directly compatible from a control circuit perspective.

Q: Does the higher current rating of the ADZS12124 (90A versus 60A) create any compatibility issues?

A: No. Higher current ratings provide additional performance margin and do not create compatibility issues. The substitute can safely handle all applications within the original part's 60A specification.

Q: What is the significance of the different contact materials?

A: The ADQM16024 uses silver alloy cadmium-free contacts, while the ADZS12124 uses silver tin oxide contacts. Both materials are suitable for general purpose relay applications. Contact material selection depends on specific load characteristics and application requirements; however, both materials are acceptable for standard switching applications.

Q: Is the ADZS12124 actively available?

A: Yes. The ADZS12124 is listed as active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete ADQM16024.

Q: How do the operating temperature ranges compare?

A: The ADZS12124 operates across -40°C to 85°C, exceeding the ADQM16024 specification of -40°C to 70°C. This provides additional thermal margin for applications operating at elevated temperatures.

Q: Are both parts RoHS compliant?

A: Yes. The ADQM16024 is RoHS compliant, and the ADZS12124 meets the newer ROHS3 standard, ensuring environmental regulation compliance for both parts.
