Key Parameters

Substitute Part Grouping Explanation

The V23079E1203B301 manufactured by TE Connectivity Potter & Brumfield Relays qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Coil Voltage: 12VDC (identical)
• Contact Form: DPDT (2 Form C) (identical)
• Mounting Type: Surface Mount (identical)
• Termination Style: Gull Wing (identical)
• Coil Type: Latching, Dual Coil (identical)
• Operating Temperature Range: -40°C ~ 85°C (encompasses ASX220A12 range)
• Must Operate Voltage: 9 VDC (compatible with ASX220A12 at 9.6 VDC)

Substitution Basis: The V23079E1203B301 maintains identical electrical interface characteristics (12VDC coil, DPDT switching), identical mechanical mounting (surface mount, gull wing termination), and identical coil actuation type (latching dual coil). The substitute part exceeds the contact rating requirement (2 A vs. 10 mA) and extends the operating temperature range, providing enhanced performance margins for the same functional application.

Parameter Comparison

Engineering Selection Recommendations

The V23079E1203B301 is the designated substitute for the obsolete ASX220A12. Selection of this alternative is supported by:

Product Status: The ASX220A12 is obsolete, while the V23079E1203B301 maintains active product status with documented inventory availability (12,279 pieces in stock), ensuring long-term supply chain viability.

Compliance Alignment: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining regulatory consistency. The V23079E1203B301 additionally carries RoHS3 compliance certification.

Functional Equivalence: Identical coil voltage (12VDC), contact configuration (DPDT), mounting method (surface mount), and coil type (latching dual coil) ensure direct functional replacement without circuit redesign.

Performance Enhancement: The substitute part provides superior contact rating (2 A vs. 10 mA), extended switching voltage capability (250VAC/220VDC vs. 10VDC), and expanded operating temperature range (-40°C to 85°C vs. -40°C to 70°C), delivering enhanced performance margins for the same application.

Frequently Asked Questions (FAQ)

Q: Can the V23079E1203B301 directly replace the ASX220A12 without PCB modifications?

A: Yes. Both components feature identical surface mount gull wing termination, matching footprint requirements. No PCB layout changes are necessary for mechanical or electrical interface compatibility.

Q: What is the primary reason for substitution?

A: The ASX220A12 is classified as obsolete. The V23079E1203B301 provides equivalent functionality with active product status and documented supply availability.

Q: Are there differences in coil current requirements?

A: Yes. The V23079E1203B301 requires 11.7 mA coil current compared to 5.8 mA for the ASX220A12. Circuit drive capability must accommodate this increased current demand. The coil resistance differs (1.03 kOhms vs. 2.06 kOhms), reflecting this change.

Q: How do contact ratings compare?

A: The ASX220A12 is rated for 10 mA maximum contact current. The V23079E1203B301 is rated for 2 A, providing 200x greater current handling capacity. Applications limited to 10 mA operation remain fully compatible.

Q: What is the switching voltage difference?

A: The ASX220A12 supports maximum 10VDC switching voltage. The V23079E1203B301 supports 250VAC or 220VDC maximum switching voltage, enabling use in higher voltage applications while remaining compatible with low-voltage circuits.

Q: Are operating temperature ranges compatible?

A: The V23079E1203B301 operating range (-40°C to 85°C) encompasses the ASX220A12 range (-40°C to 70°C). The substitute part provides 15°C additional high-temperature margin.

Q: Do contact materials differ?

A: Yes. The ASX220A12 uses Silver Palladium (AgPd) and Gold (Au) contacts. The V23079E1203B301 uses Silver Nickel (AgNi) and Gold (Au). Both material systems provide reliable contact performance for telecom and general-purpose applications.

Q: What packaging format is available for the V23079E1203B301?

A: The substitute part is supplied in Cut Tape (CT) packaging format, standard for surface mount component distribution.
