DS2E-ML-DC12V Equivalent & Substitute Parts

Part Overview

The DS2E-ML-DC12V is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 2A contact rating at 12VDC coil voltage. This through-hole mounted relay is designed for applications requiring dual-pole, dual-throw switching functionality with sealed construction. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this relay type remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-ML-DC12V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: Must be 12VDC
• Contact Form: Must be DPDT (2 Form C)
• Contact Rating: Must be 2 A minimum
• Switching Voltage: Must support 250VAC, 220VDC - Max
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin
• Coil Type: Must be Latching, Single Coil

The V23079C1103B301 manufactured by TE Connectivity Potter & Brumfield Relays meets all mandatory substitution criteria. Both relays share identical coil voltage, contact configuration, current rating, switching voltage capability, mounting method, and termination style. Variations in coil current, operate/release times, and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The V23079C1103B301 is a direct functional equivalent for the DS2E-ML-DC12V. Selection between these parts should be based on the following factors:

For new designs or long-term applications: The V23079C1103B301 is recommended due to its active product status, ensuring ongoing availability and supply chain continuity. This part also offers improved coil efficiency (5.8 mA versus 15 mA) and faster switching response times (4 ms operate and release versus 10 ms and 5 ms respectively).

For legacy system maintenance: Either part is electrically and mechanically compatible. The DS2E-ML-DC12V may be selected if existing inventory is available, provided the application does not require the extended operating temperature range (-40°C ~ 85°C) offered by the V23079C1103B301.

Compliance considerations: The V23079C1103B301 carries RoHS Compliant certification, while the DS2E-ML-DC12V does not specify RoHS status. Both parts are classified as EAR99 and share identical HTSUS codes (8536.41.0020).

Frequently Asked Questions (FAQ)

Q: Can the V23079C1103B301 replace the DS2E-ML-DC12V in existing applications?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (DPDT), current rating (2A), switching voltage capability (250VAC, 220VDC), mounting type (through hole), and termination style (PC pin). The substitute part operates faster and with lower coil current, making it functionally superior in most applications.

Q: What are the differences in coil current between these parts?

A: The DS2E-ML-DC12V requires 15 mA coil current, while the V23079C1103B301 requires 5.8 mA. The lower coil current of the substitute part reduces power consumption and heat generation in the relay coil, which may improve overall circuit efficiency.

Q: Are there differences in switching speed?

A: Yes. The DS2E-ML-DC12V has an operate time of 10 ms and release time of 5 ms. The V23079C1103B301 operates and releases in 4 ms each. Applications with strict timing requirements should account for these differences during circuit validation.

Q: What is the operating temperature difference?

A: The DS2E-ML-DC12V operates from -40°C to 70°C, while the V23079C1103B301 operates from -40°C to 85°C. The substitute part supports a wider high-temperature range, making it suitable for applications in elevated ambient conditions.

Q: Are the contact materials compatible?

A: Both relays use gold-plated contacts. The DS2E-ML-DC12V uses silver and gold, while the V23079C1103B301 uses silver nickel and gold. Both material combinations are suitable for general-purpose switching applications at the 2A rating.

Q: What is the packaging difference?

A: The DS2E-ML-DC12V is supplied in standard packaging, while the V23079C1103B301 is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Why is the DS2E-ML-DC12V obsolete?

A: Product obsolescence is determined by the manufacturer. The V23079C1103B301 remains in active production and is the recommended source for new procurement.
