Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX210A03 is based on the following critical parameters:

• Coil Voltage: 3VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration (exact match required)
• Mounting Type: Surface Mount with Gull Wing termination (exact match required)
• Operating Temperature Range: Minimum -40°C to 70°C coverage
• Contact Rating: Minimum 10 mA capability

The V23079F1108B301 qualifies as a substitute because it maintains identical coil voltage, contact form, mounting type, and termination style. While the substitute exhibits higher contact rating (2 A) and switching voltage capability (250VAC, 220VDC), these represent functional enhancements that do not compromise compatibility in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1108B301 is an active product from TE Connectivity Potter & Brumfield Relays and represents the primary substitute for the obsolete ASX210A03. Selection of this substitute is supported by:

• Identical coil voltage (3VDC) and contact form (DPDT 2 Form C)
• Matching surface mount gull wing termination
• Active product status with current manufacturing and supply chain availability
• RoHS compliance certification
• Extended operating temperature range (-40°C ~ 85°C) providing broader environmental coverage than the original part

The higher contact rating (2 A versus 10 mA) and increased switching voltage capability (250VAC, 220VDC versus 10VDC) do not create incompatibility; these parameters represent performance enhancements suitable for applications originally specified for the ASX210A03.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1108B301 directly replace the ASX210A03 in existing designs?

A: Yes. Both parts share identical coil voltage (3VDC), contact form (DPDT 2 Form C), mounting type (surface mount), and termination style (gull wing). The substitute's higher contact rating and switching voltage represent functional improvements that maintain backward compatibility.

Q: What is the primary reason for substitution?

A: The ASX210A03 is classified as obsolete. The V23079F1108B301 is an active product with current manufacturing support and supply availability.

Q: Are there packaging differences between these parts?

A: The ASX210A03 packaging is listed as standard, while the V23079F1108B301 is supplied in Tape & Reel (TR) format. Both maintain identical surface mount gull wing termination suitable for automated assembly processes.

Q: How do the coil currents differ?

A: The ASX210A03 requires 11.7 mA coil current, while the V23079F1108B301 requires 23.3 mA. Circuit designs must accommodate the higher coil current draw of the substitute part.

Q: Are there compliance differences?

A: The V23079F1108B301 carries RoHS compliance certification and Moisture Sensitivity Level (MSL) 3 rating. The ASX210A03 REACH status is listed as unaffected. Both parts carry EAR99 ECCN classification.

Q: What is the operating temperature difference?

A: The ASX210A03 operates from -40°C to 70°C, while the V23079F1108B301 extends to -40°C to 85°C, providing 15°C additional high-temperature capability.
