DS2E-ML2-DC12V Equivalent & Substitute Parts

Part Overview

The DS2E-ML2-DC12V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 2A switching capacity at 12VDC coil voltage. This through-hole mounted relay is designed for applications requiring dual-coil latching operation with sealed construction. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-ML2-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, Dual Coil

The V23079B1203B301 manufactured by TE Connectivity Potter & Brumfield Relays meets all mandatory substitution criteria. Both relays share identical functional specifications for coil voltage, contact configuration, current rating, and switching voltage capability. Both employ through-hole PC pin termination and dual-coil latching operation, enabling direct functional replacement in legacy applications.

Engineering Selection Recommendations

The V23079B1203B301 is the qualified substitute for the DS2E-ML2-DC12V based on functional equivalence across all mandatory electrical and mechanical parameters. The substitute part is currently in active production status, ensuring availability for replacement and new applications. The V23079B1203B301 carries ROHS3 compliance certification, providing environmental regulatory advantage over the obsolete original part. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring consistent export and regulatory compliance.

The substitute exhibits improved performance characteristics: lower coil current (11.7 mA vs. 30 mA), faster switching times (4 ms operate and release vs. 10 ms and 5 ms), and extended operating temperature range (-40°C to 85°C vs. -40°C to 70°C). These performance improvements do not compromise compatibility and may provide operational benefits in temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1203B301 directly replace the DS2E-ML2-DC12V in existing circuits?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (DPDT), current rating (2A), switching voltage (250VAC, 220VDC), mounting type (through-hole), and termination style (PC pin). Direct functional replacement is supported without circuit modification.

Q: What are the key differences between these two relays?

A: The substitute part exhibits lower coil current consumption (11.7 mA vs. 30 mA), faster switching response (4 ms vs. 10 ms operate time), and wider operating temperature range (-40°C to 85°C vs. -40°C to 70°C). Coil resistance differs (1.03 kOhms vs. 400 Ohms) due to design optimization. Contact material composition varies slightly (AgNi vs. Ag in the substitute).

Q: Is the V23079B1203B301 available in the same packaging as the original part?

A: The original DS2E-ML2-DC12V uses standard through-hole PC pin termination. The V23079B1203B301 is supplied in tube packaging and maintains identical through-hole PC pin termination, ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What compliance certifications apply to the substitute part?

A: The V23079B1203B301 is ROHS3 compliant and maintains REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications.

Q: Are there any circuit design considerations when substituting this part?

A: The substitute part's lower must-operate voltage (9 VDC vs. 8.4 VDC) and higher coil resistance should be evaluated in circuits with marginal supply voltage or current-limited drive circuits. The faster switching times may benefit noise-sensitive applications. No other design modifications are required for functional substitution.
