ASX210A12 Equivalent & Substitute Parts

Part Overview

The ASX210A12 is a telecom relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10 mA contact rating and 12VDC coil voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications. The telecom-grade design and latching single-coil architecture define its operational characteristics and substitution parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX210A12 is determined by the following critical parameters:

• Contact Configuration: DPDT (2 Form C) form factor is mandatory for functional equivalence
• Coil Voltage: 12VDC operation is required for direct circuit compatibility
• Mounting Type: Surface Mount with Gull Wing termination ensures PCB compatibility
• Coil Type: Latching, Single Coil architecture must be preserved
• Contact Rating: The 10 mA specification establishes the minimum current-handling requirement; substitutes with equal or higher ratings are acceptable
• Operating Temperature: The -40°C ~ 70°C range defines the environmental operating envelope
• Regulatory Compliance: REACH and ECCN classifications must align with application requirements

The V23079F1103B301 qualifies as a substitute based on matching contact configuration, coil voltage, mounting type, coil type, and termination style. The higher contact rating (2 A vs. 10 mA) and extended temperature range (-40°C ~ 85°C) provide operational margin without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1103B301 is suitable as a substitute for the obsolete ASX210A12 based on the following factors:

• Active Product Status: The V23079F1103B301 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Functional Equivalence: Both relays share identical contact configuration (DPDT), coil voltage (12VDC), mounting type (Surface Mount), and coil type (Latching, Single Coil)
• Enhanced Specifications: The substitute provides higher contact rating (2 A vs. 10 mA) and extended operating temperature range (-40°C ~ 85°C vs. -40°C ~ 70°C), offering operational margin
• Regulatory Compliance: The V23079F1103B301 is RoHS Compliant, meeting modern environmental standards
• Packaging Availability: The substitute is available in Tape & Reel (TR) packaging, supporting automated assembly processes

Circuit design modifications may be required to accommodate the lower coil resistance (2.06 kOhms vs. 4.11 kOhms) and higher coil current (5.8 mA vs. 2.9 mA) of the substitute. Verification of drive circuit compatibility is necessary before implementation.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1103B301 directly replace the ASX210A12 without PCB modifications?

A: Direct pin-compatible replacement is possible due to matching Surface Mount Gull Wing termination. However, the lower coil resistance and higher coil current of the substitute may require drive circuit adjustment to ensure proper relay operation and prevent excessive current draw.

Q: What is the significance of the higher contact rating (2 A vs. 10 mA) in the substitute?

A: The V23079F1103B301 contact rating of 2 A exceeds the ASX210A12 specification of 10 mA, providing operational margin for higher-current switching applications. This does not compromise compatibility with lower-current circuits; the relay will function correctly at the original 10 mA specification.

Q: Are there differences in switching performance between these relays?

A: The V23079F1103B301 exhibits faster switching times (4 ms operate and release vs. 5 ms for the ASX210A12). This faster response may be advantageous in time-sensitive applications but requires verification that downstream circuits can accommodate the reduced switching delay.

Q: What packaging considerations apply to the substitute?

A: The V23079F1103B301 is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The ASX210A12 packaging format is not specified in available data. Confirm packaging compatibility with assembly equipment and processes.

Q: How does the extended temperature range of the substitute affect compatibility?

A: The V23079F1103B301 operating range of -40°C ~ 85°C encompasses the ASX210A12 range of -40°C ~ 70°C. The extended upper temperature limit provides additional thermal margin and is fully compatible with applications designed for the original component.

Q: What regulatory compliance differences exist between the two relays?

A: The V23079F1103B301 is RoHS Compliant, meeting current environmental regulations. The ASX210A12 REACH status is listed as REACH Unaffected. Confirm that RoHS compliance is required for your application before selecting the substitute.
