Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS2E-SL-DC3V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 3VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Contact Rating: 2A minimum
• Switching Voltage: 250VAC, 220VDC capability
• Mounting Type: Through Hole with PC Pin termination
• Coil Type: Latching, Single Coil operation

The V23079C1108B301 manufactured by TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. Both relays share identical functional specifications for coil voltage, contact configuration, current rating, and switching voltage. Both are sealed, through-hole mounted components with PC pin termination suitable for PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

The V23079C1108B301 is the qualified substitute for the DS2E-SL-DC3V based on functional equivalence and product availability. The substitute part maintains all critical electrical specifications: identical 3VDC coil voltage, DPDT contact configuration, 2A contact rating, and 250VAC/220VDC switching capability.

The V23079C1108B301 offers operational advantages including lower coil current (23.3 mA vs. 30 mA), faster switching response (4 ms operate and release times vs. 10 ms and 5 ms), and an extended operating temperature range (-40°C to 85°C vs. -40°C to 70°C). The substitute part is currently in active production status with RoHS compliance certification, ensuring long-term availability and regulatory alignment.

Minor differences exist in coil resistance (128 Ohms vs. 100 Ohms) and must-operate voltage (2.25 VDC vs. 2.1 VDC), which remain within acceptable tolerance for general purpose relay applications. Contact material composition differs slightly (Silver Nickel vs. pure Silver), with both configurations suitable for the specified switching voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the V23079C1108B301 directly replace the DS2E-SL-DC3V in existing designs?

A: Yes. Both relays share identical coil voltage (3VDC), contact configuration (DPDT), current rating (2A), and switching voltage specifications (250VAC, 220VDC). Through-hole mounting and PC pin termination are identical, allowing direct PCB substitution.

Q: What are the differences in switching speed between these relays?

A: The V23079C1108B301 operates faster, with 4 ms operate and release times compared to 10 ms operate and 5 ms release times for the DS2E-SL-DC3V. This faster response may benefit applications requiring rapid switching but does not prevent substitution in designs tolerating the original timing.

Q: Does the lower coil current of the V23079C1108B301 affect circuit design?

A: The substitute part draws 23.3 mA versus 30 mA, reducing power consumption. Existing drive circuits designed for 30 mA will operate the substitute part without modification. The higher coil resistance (128 Ohms vs. 100 Ohms) is consistent with the lower current specification.

Q: Are there packaging differences between these parts?

A: The DS2E-SL-DC3V uses standard packaging, while the V23079C1108B301 is supplied in tube packaging. Both are through-hole components with identical pin configurations and PCB footprints.

Q: What is the temperature operating range difference?

A: The V23079C1108B301 operates across -40°C to 85°C, extending 15°C above the DS2E-SL-DC3V range of -40°C to 70°C. This provides additional thermal margin for applications in elevated temperature environments.

Q: Is the V23079C1108B301 RoHS compliant?

A: Yes, the V23079C1108B301 is RoHS compliant. The DS2E-SL-DC3V status is not specified in available documentation.
