DS2E-ML2-DC3V Equivalent & Substitute Parts

Part Overview

The DS2E-ML2-DC3V is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) with 2A contact rating and 3VDC coil voltage. This through-hole mounted relay is designed for applications requiring dual-coil latching operation with sealed contacts rated for 250VAC and 220VDC switching.

The DS2E-ML2-DC3V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-ML2-DC3V is determined by strict alignment with the following critical parameters:

• Coil voltage: 3VDC (exact match required)
• Contact form: DPDT (2 Form C) configuration
• Contact rating: 2A minimum
• Coil type: Latching, dual coil operation
• Mounting: Through hole with PC pin termination
• Switching capability: 250VAC / 220VDC minimum

The V23079B1208B301 manufactured by TE Connectivity Potter & Brumfield Relays satisfies all mandatory substitution criteria. Both relays share identical coil voltage, contact form, current rating, switching voltage capability, coil type, mounting method, and termination style. Variations in coil current, operate/release timing, and operating temperature range do not preclude functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1208B301 is the qualified substitute for the DS2E-ML2-DC3V. Selection is supported by the following factors:

• Both relays meet identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage.
• The V23079B1208B301 maintains active product status with current manufacturing support, addressing the obsolescence of the DS2E-ML2-DC3V.
• The substitute demonstrates superior compliance posture: RoHS3 compliant status versus unspecified compliance for the original part.
• Extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) provides additional thermal margin.
• Lower coil current (46.7 mA versus 120 mA) reduces power consumption in the control circuit.
• Faster switching response (4 ms operate and release versus 10 ms and 5 ms) may improve system performance characteristics.

Both parts carry identical REACH and ECCN classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1208B301 directly replace the DS2E-ML2-DC3V in existing designs?

A: Yes. Both relays share identical coil voltage (3VDC), contact form (DPDT), current rating (2A), switching voltage (250VAC/220VDC), coil type (latching dual coil), mounting method (through hole), and termination style (PC pin). Physical footprint compatibility must be confirmed through dimensional drawings.

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

A: The V23079B1208B301 operates with lower coil current (46.7 mA versus 120 mA), faster switching times (4 ms versus 10 ms operate and 5 ms release), and an extended operating temperature range (-40°C to 85°C versus -40°C to 70°C). Contact material composition differs slightly (AgNi versus Ag in the substitute). These differences do not affect functional equivalence within the specified electrical parameters.

Q: Are there any compliance or regulatory differences?

A: The V23079B1208B301 carries RoHS3 compliance certification, while the DS2E-ML2-DC3V compliance status is not specified. Both parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: What should be verified before implementing a substitution?

A: Confirm physical footprint and pin spacing compatibility using manufacturer datasheets. Verify that the lower coil current requirement (46.7 mA) is compatible with existing drive circuitry. Confirm that faster switching response times do not introduce timing conflicts in the application. Validate that the extended operating temperature range meets or exceeds application requirements.

Q: Is the V23079B1208B301 available in equivalent quantities?

A: Current inventory status indicates 952 pieces of the V23079B1208B301 are available as new original stock, supporting production and maintenance requirements.
