ASX210A4H Equivalent & Substitute Parts

Part Overview

The ASX210A4H is a telecom relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 4.5VDC coil. This surface mount component is designed for telecommunications applications with low-current switching capability (10 mA contact rating). The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX210A4H is determined by the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Contact Form: DPDT (2 Form C) configuration
• Coil Voltage: 4.5VDC nominal
• Mounting Type: Surface Mount
• Termination Style: Gull Wing

Allowable Parameter Variations:

• Contact Rating (Current): The substitute may exceed the original 10 mA rating, provided it does not reduce system performance
• Switching Voltage: The substitute may exceed the original 10VDC maximum
• Operating Temperature Range: The substitute may extend beyond the original -40°C ~ 70°C range
• Coil Resistance: Minor variations are acceptable within the latching, single-coil architecture
• Product Status: Active parts are preferred over obsolete classifications

The V23079F1111B301 qualifies as a substitute based on matching contact form, coil voltage, mounting type, and termination style, while providing enhanced current-handling capability and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The V23079F1111B301 serves as the primary substitute for the obsolete ASX210A4H. Selection of this alternative is supported by the following engineering factors:

Functional Compatibility: Both relays maintain identical contact form (DPDT), coil voltage (4.5VDC), mounting configuration (surface mount), and termination style (gull wing), ensuring direct functional replacement in circuit designs.

Product Status Advantage: The V23079F1111B301 is classified as active with current manufacturing availability, eliminating supply chain constraints associated with the obsolete ASX210A4H.

Compliance and Certification: The V23079F1111B301 carries RoHS compliance certification, meeting modern regulatory requirements. Both parts share the same ECCN (EAR99) and HTSUS classification (8536.41.0020).

Enhanced Performance Characteristics: The substitute provides increased contact current rating (2 A versus 10 mA), extended switching voltage capability (250VAC/220VDC versus 10VDC), and expanded operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). These enhancements do not compromise compatibility with applications designed for the original part.

Coil Resistance Consideration: The substitute exhibits lower coil resistance (289 Ohms versus 579 Ohms), resulting in approximately 2.0x higher coil current draw. Circuit designs must accommodate this increased current requirement during coil energization.

Frequently Asked Questions (FAQ)

Q: Can the V23079F1111B301 directly replace the ASX210A4H in existing PCB designs?

A: Yes, provided the circuit design accommodates the lower coil resistance (289 Ohms versus 579 Ohms). The substitute draws approximately 15.6 mA coil current at 4.5VDC, compared to the original 7.8 mA. Verify that the coil drive circuit can supply this increased current without exceeding component ratings.

Q: What is the primary reason for substitution?

A: The ASX210A4H is classified as obsolete. The V23079F1111B301 provides equivalent functionality with active manufacturing status and improved compliance certifications.

Q: Are the contact switching characteristics compatible?

A: The operate and release times differ slightly (V23079F1111B301: 4 ms operate / 6 ms release versus ASX210A4H: 5 ms operate / 5 ms release). For timing-critical applications, verify that these variations do not impact system performance.

Q: Does packaging differ between these parts?

A: Both parts use surface mount gull wing termination. The V23079F1111B301 is supplied in Tape & Reel (TR) packaging, while the ASX210A4H packaging format is not specified in available documentation.

Q: What is the impact of the higher contact current rating?

A: The V23079F1111B301 supports 2 A contact current versus the original 10 mA rating. This enhancement allows the substitute to handle higher-current switching applications without performance degradation. Applications limited to 10 mA operation remain fully compatible.

Q: Are there compliance differences?

A: The V23079F1111B301 is RoHS compliant. The ASX210A4H RoHS status is not specified. Both parts carry identical ECCN and HTSUS classifications.
