ADQ23Q024 Equivalent & Substitute Parts

Part Overview

The ADQ23Q024 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 30A at 250VAC maximum switching voltage and is designed for applications requiring latching, dual-coil operation. The part is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADQ23Q024 is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Matching Parameters:

• Coil voltage: 24VDC
• Contact form: SPST-NO (1 Form A)
• Coil type: Latching, dual coil
• Must operate voltage: 16.8 VDC minimum
• Contact material: Silver Tin Oxide (AgSnO)

Allowable Variation Parameters:

• Contact rating (current): May be equal or higher than 30A
• Switching voltage: May be equal or higher than 250VAC
• Mounting type: May differ based on circuit board design requirements
• Termination style: May differ based on board layout compatibility
• Operating temperature range: May be equal or wider than -40°C ~ 65°C

The ADZS22124 qualifies as a substitute because it maintains all mandatory parameters while providing enhanced current rating (90A vs. 30A) and higher maximum switching voltage (276VAC vs. 250VAC). The primary design trade-off involves mounting type (chassis mount vs. through hole) and termination style (screw terminal vs. PC pin quick connect), which require circuit board layout evaluation.

Parameter Comparison

Engineering Selection Recommendations

The ADZS22124 is the identified substitute for the obsolete ADQ23Q024. Both components are manufactured by Panasonic Electric Works and maintain identical coil voltage, contact form, and coil type specifications. The ADZS22124 is currently in active production status, ensuring long-term availability for new designs and replacement applications.

Compliance Considerations:

• ADQ23Q024: RoHS Compliant
• ADZS22124: ROHS3 Compliant (enhanced environmental compliance standard)

Both parts carry identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Design Integration Requirements: The primary consideration for substitution involves mechanical integration. The ADQ23Q024 uses through-hole PC pin quick-connect termination, while the ADZS22124 employs chassis-mount screw terminal configuration. Circuit board layout modifications and mechanical mounting bracket redesign are necessary. The ADZS22124's higher current rating (90A vs. 30A) and switching voltage capability (276VAC vs. 250VAC) provide design margin for applications operating near the original part's limits.

Frequently Asked Questions (FAQ)

Q: Can the ADZS22124 directly replace the ADQ23Q024 without circuit board modifications?

A: No. While the electrical specifications are compatible, the mounting type and termination style differ. The ADQ23Q024 is through-hole mounted with PC pin quick-connect terminals, whereas the ADZS22124 is chassis-mounted with screw terminals. Circuit board layout and mechanical mounting bracket modifications are required.

Q: What are the key electrical parameters that make the ADZS22124 a valid substitute?

A: The ADZS22124 maintains the critical electrical specifications: 24VDC coil voltage, SPST-NO contact form, latching dual-coil operation, 16.8VDC must-operate voltage, and Silver Tin Oxide contact material. These parameters ensure functional compatibility in the application circuit.

Q: Does the higher current rating of the ADZS22124 (90A vs. 30A) affect circuit operation?

A: No. Higher current rating provides additional design margin and does not negatively impact circuit operation. The relay will function identically in applications designed for 30A operation. The higher rating simply indicates the component can handle greater load without degradation.

Q: Are there temperature range differences between these parts?

A: Yes. The ADQ23Q024 operates from -40°C to 65°C, while the ADZS22124 operates from -40°C to 85°C. The ADZS22124 provides extended high-temperature capability, which is beneficial for applications in elevated ambient conditions.

Q: What is the impact of the different coil resistance values (576 Ohms vs. 192 Ohms)?

A: The coil resistance difference reflects the different coil designs. The ADZS22124's lower resistance (192 Ohms) results in higher coil current (125 mA vs. 41.7 mA) at the same 24VDC supply voltage. This requires evaluation of the coil drive circuit to ensure adequate current supply capability.

Q: Are both parts RoHS compliant?

A: Yes. The ADQ23Q024 is RoHS Compliant, and the ADZS22124 is ROHS3 Compliant. ROHS3 represents an enhanced environmental compliance standard. Both parts meet regulatory requirements for restricted substance elimination.

Q: What is the inventory status of these parts?

A: The ADQ23Q024 (obsolete) has 1077 pieces in stock. The ADZS22124 (active product) has 903 pieces in stock. The active status of the ADZS22124 ensures continued availability for future orders beyond current inventory levels.
