Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX22012 is based on the following critical parameters that must align for functional compatibility:

Core Electrical Parameters:

• Coil voltage: 12VDC (primary control signal requirement)
• Contact form: DPDT (2 Form C) (switching topology requirement)
• Mounting type: Through Hole (PCB integration requirement)
• Termination style: PC Pin (connection interface requirement)

Performance Parameters:

• Contact rating must equal or exceed 10 mA minimum
• Switching voltage capability must support application requirements
• Operating temperature range must encompass -40°C minimum
• Operate and release times must be compatible with system timing

The V23079B1203B301 qualifies as a substitute based on matching all core electrical parameters while providing enhanced contact rating (2 A versus 10 mA) and improved operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

The V23079B1203B301 is an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), providing superior long-term availability compared to the obsolete ASX22012. Both components share identical coil voltage, contact form, mounting type, and termination style, establishing direct functional compatibility at the circuit interface level.

The V23079B1203B301 demonstrates enhanced electrical performance with 2 A contact rating versus 10 mA, broader switching voltage capability (250VAC/220VDC versus 10VDC), and extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). These characteristics position the V23079B1203B301 as a capable substitute for applications where the ASX22012 is no longer available.

Circuit design verification is required to confirm that the increased coil current (11.7 mA versus 5.8 mA) and reduced coil resistance (1.03 kOhms versus 2.06 kOhms) are compatible with existing drive circuitry.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1203B301 directly replace the ASX22012 in existing designs?

A: Direct pin-for-pin replacement is possible due to matching contact form (DPDT), coil voltage (12VDC), mounting type (Through Hole), and termination style (PC Pin). However, the increased coil current requirement (11.7 mA versus 5.8 mA) must be evaluated against existing drive circuit capacity.

Q: What are the key differences between these relays?

A: The primary differences are contact rating (2 A versus 10 mA), switching voltage capability (250VAC/220VDC versus 10VDC), operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C), and coil resistance (1.03 kOhms versus 2.06 kOhms). The V23079B1203B301 is classified as general purpose versus telecom for the ASX22012.

Q: Are there packaging considerations for substitution?

A: The ASX22012 uses standard packaging while the V23079B1203B301 is supplied in tube packaging. Both maintain Through Hole mounting and PC Pin termination, ensuring PCB footprint compatibility.

Q: What compliance certifications apply to the substitute part?

A: The V23079B1203B301 is ROHS3 compliant with REACH unaffected status. Both components share EAR99 ECCN classification and identical HTSUS code (8536.41.0020).

Q: How do the switching characteristics compare?

A: The V23079B1203B301 provides faster switching with 4 ms operate and release times versus 5 ms for the ASX22012. This faster response may require timing verification in applications with strict temporal requirements.
