ASX22009 Equivalent & Substitute Parts

Part Overview

The ASX22009 is a telecom relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10 mA contact rating and 9VDC coil voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The through-hole mounting and latching dual-coil design serve specific telecom applications requiring reliable switching at low current levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX22009 is based on the following critical parameters that must align between the main part and substitute:

• Coil Voltage: 9VDC (exact match required for direct circuit compatibility)
• Contact Form: DPDT (2 Form C) (functional switching configuration must be identical)
• Mounting Type: Through Hole (physical installation compatibility)
• Termination Style: PC Pin (PCB connection method)
• Coil Type: Latching, Dual Coil (operational behavior requirement)

The V23079B1206B301 qualifies as a substitute based on these core parameters. While the substitute exhibits higher contact current rating (2 A versus 10 mA) and broader switching voltage capability, these represent enhanced performance characteristics that do not prevent substitution in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1206B301 is an active product with current manufacturing support, whereas the ASX22009 is obsolete. Both components share identical coil voltage (9VDC), contact configuration (DPDT), mounting method (through hole), and coil type (latching, dual coil), establishing functional equivalence for circuit-level substitution.

The V23079B1206B301 demonstrates enhanced specifications including higher contact current capacity (2 A versus 10 mA), extended operating temperature range (-40°C to 85°C versus -40°C to 70°C), and RoHS compliance. These characteristics provide superior performance margins in applications originally designed for the ASX22009.

Selection of the V23079B1206B301 is supported by its active product status, ensuring availability and long-term supply chain stability. The component meets the same export control classification (EAR99) as the original part.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1206B301 directly replace the ASX22009 in existing designs?

A: Yes. Both relays share identical coil voltage (9VDC), DPDT contact configuration, through-hole mounting, PC pin termination, and latching dual-coil operation. The substitute's higher contact current rating and extended temperature range do not prevent direct substitution in circuits designed for the original specification.

Q: What is the significance of the higher contact current rating in the V23079B1206B301?

A: The V23079B1206B301 is rated for 2 A contact current compared to the ASX22009's 10 mA rating. This represents enhanced capability that provides additional performance margin. Applications operating within the original 10 mA specification will function without modification.

Q: How do the coil resistance values differ, and does this affect substitution?

A: The ASX22009 has 1.15 kOhms coil resistance while the V23079B1206B301 has 578 Ohms. The substitute's lower resistance results in higher coil current (15.6 mA versus 7.8 mA) at the same 9VDC supply voltage. Circuit designs must accommodate this increased current draw during coil energization.

Q: Are there packaging differences between these relays?

A: The ASX22009 uses standard through-hole packaging with PC pins. The V23079B1206B301 is supplied in tube packaging. Both employ identical mounting and termination methods, ensuring PCB compatibility.

Q: What is the operating temperature consideration for substitution?

A: The ASX22009 operates from -40°C to 70°C, while the V23079B1206B301 extends to -40°C to 85°C. The substitute provides a wider temperature envelope, beneficial for applications requiring extended thermal range operation.

Q: Does the V23079B1206B301 meet compliance requirements equivalent to the ASX22009?

A: Both components share EAR99 export control classification. The V23079B1206B301 is RoHS compliant, providing additional regulatory alignment for modern manufacturing environments. The ASX22009's compliance status for RoHS is not specified in available documentation.
