ADQ13Q04H Equivalent & Substitute Parts

Part Overview

The ADQ13Q04H is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 4.5VDC coil. This through-hole mounted relay is rated for 30A at 250VAC maximum switching voltage, with a maximum switching load of 7500VA. The part is currently obsolete, making equivalent substitutes necessary for new designs or maintenance applications requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADQ13Q04H is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Contact form: SPST-NO (1 Form A) configuration maintained
• Coil type: Latching, single coil operation
• Contact material: Silver Tin Oxide (AgSnO)
• Relay type: General purpose
• Switching voltage capability: Minimum 250VAC
• Current rating: Minimum 30A
• Operating temperature range: Minimum -40°C to 65°C coverage
• Coil voltage: Compatible with 4.5VDC supply circuits (allowing for voltage tolerance margins)

The ADZS12105 qualifies as a substitute based on these parameters. While it features a higher coil voltage (5VDC) and current rating (90A), it maintains the same contact form, coil type, contact material, and exceeds the switching voltage and load requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

The ADZS12105 is suitable as a substitute for the ADQ13Q04H based on the following factors:

Compliance and Status: The ADZS12105 is an active product with ROHS3 compliance, whereas the ADQ13Q04H is obsolete. Both parts carry EAR99 ECCN classification and share the same HTSUS code (8536.41.0050), indicating equivalent tariff treatment.

Functional Equivalence: Both relays maintain identical contact form (SPST-NO), coil type (latching, single coil), and contact material (Silver Tin Oxide). Switching times are identical at 20 ms for both operate and release.

Performance Margins: The ADZS12105 exceeds the electrical specifications of the ADQ13Q04H in current rating (90A vs. 30A), switching voltage (276VAC vs. 250VAC), and maximum switching load (24840VA vs. 7500VA). The extended operating temperature range (-40°C to 85°C vs. -40°C to 65°C) provides additional environmental coverage.

Design Considerations: The coil voltage difference (5VDC vs. 4.5VDC) and increased coil current (300mA vs. 111mA) require circuit verification to ensure the power supply and control circuitry can accommodate the higher voltage and current requirements. The mounting type change from through-hole to chassis mount and termination style change from PC pin to screw terminal necessitate mechanical redesign of the PCB layout and interconnection scheme.

Frequently Asked Questions (FAQ)

Q: Can the ADZS12105 directly replace the ADQ13Q04H without circuit modifications?

A: No. While both relays share the same contact form and coil type, the ADZS12105 requires a 5VDC coil supply versus the ADQ13Q04H's 4.5VDC requirement. The control circuit must be verified to supply 5VDC and accommodate the increased coil current of 300mA. Additionally, the mounting and termination styles differ, requiring PCB layout changes.

Q: What are the key electrical parameters that make these relays functionally equivalent?

A: Both relays maintain SPST-NO contact configuration, latching single-coil operation, and Silver Tin Oxide contact material. Both achieve 20 ms operate and release times. The ADZS12105 meets or exceeds all switching voltage and current requirements of the ADQ13Q04H.

Q: Does the higher current rating of the ADZS12105 affect compatibility?

A: The higher current rating (90A vs. 30A) is not a compatibility issue; it represents increased capability. The relay will function correctly in circuits designed for 30A operation. However, the coil voltage and current differences must be addressed in the control circuit design.

Q: Are there packaging or inventory considerations?

A: The ADQ13Q04H is obsolete with 902 pieces in stock. The ADZS12105 is an active product with 1034 pieces available in tray packaging. For new designs or long-term production, the ADZS12105 is the recommended choice due to its active status and continued availability.

Q: How do the operating temperature ranges compare?

A: The ADQ13Q04H operates from -40°C to 65°C, while the ADZS12105 operates from -40°C to 85°C. The ADZS12105 provides a 20°C extended upper temperature limit, suitable for applications requiring higher thermal tolerance.
