Key Parameters

Substitute Part Grouping Explanation

The ZC-Q55 manufactured by Omron Automation and Safety qualifies as a functional substitute for the AZH2031 based on the following critical parameters:

Matching Parameters:

• Circuit configuration: Both are SPDT switches
• Switch function: Both operate in On-Momentary mode
• Actuator type: Both feature round pin plunger actuation
• Mounting type: Both are panel mount devices
• Termination style: Both use screw terminals
• Ingress protection: Both meet IP67 specification
• Operating temperature range: Both operate from -10°C to 80°C
• Voltage rating (AC): Both rated at 125V AC
• Voltage rating (DC): Both rated at 30V DC

Differing Parameters: The ZC-Q55 provides higher current capacity (10A AC / 6A DC versus 5A AC/DC) and extended electrical life (500,000 cycles versus 100,000 cycles), making it suitable for applications requiring the AZH2031's specifications while offering improved performance margins.

Parameter Comparison

Engineering Selection Recommendations

The ZC-Q55 is the appropriate substitute for the AZH2031 in applications requiring SPDT snap action switching at 125V AC and 30V DC. The substitute maintains electrical and mechanical compatibility across all critical interface parameters while offering enhanced current capacity and extended electrical life.

The AZH2031's obsolete status necessitates transition to active production alternatives. The ZC-Q55 carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Both devices meet identical ingress protection, temperature operating range, and mechanical actuation specifications, supporting direct functional replacement in panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the ZC-Q55 directly replace the AZH2031 in existing designs?

A: Yes. Both switches share identical circuit configuration (SPDT), switch function (On-Momentary), actuator type (round pin plunger), mounting type (panel mount), termination style (screw terminal), and ingress protection rating (IP67). Voltage and temperature specifications are identical. The ZC-Q55 provides higher current capacity, which does not prevent substitution in applications designed for the AZH2031's 5A rating.

Q: What are the key differences between these switches?

A: The primary differences are current rating (ZC-Q55 rated 10A AC / 6A DC versus AZH2031 rated 5A AC/DC), electrical life (ZC-Q55 rated 500,000 cycles versus AZH2031 rated 100,000 cycles), and product status (ZC-Q55 is active; AZH2031 is obsolete). Operating position differs (ZC-Q55 at 1.504" versus AZH2031 at 0.685"), which may affect mechanical integration in space-constrained applications.

Q: Are there packaging considerations for substitution?

A: The AZH2031 is supplied with standard packaging, while the ZC-Q55 is supplied in bulk packaging. Procurement processes should account for packaging format differences when ordering replacement inventory.

Q: Do both switches meet current regulatory requirements?

A: The AZH2031 is RoHS Compliant. The ZC-Q55 is ROHS3 Compliant, representing the current regulatory standard. Both devices carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory alignment for industrial automation applications.
