Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2Y-SL2-DC3V is determined by strict alignment with the following critical parameters:

• Contact Form: DPDT (2 Form C) configuration
• Contact Rating: 2 A minimum
• Coil Voltage: 3VDC
• Coil Type: Latching, Dual Coil operation
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Switching Voltage: 250VAC, 220VDC - Max capability

The substitute part V23079B1208B301 meets all mandatory electrical and mechanical parameters required for direct substitution. This part maintains identical contact form, current rating, coil voltage, coil type, mounting configuration, and termination style. The substitute part is classified as active product status, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1208B301 is the qualified substitute for the DS2Y-SL2-DC3V based on the following criteria:

Product Status Alignment: The substitute part is classified as active product status, providing assured long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Certification: Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory compliance equivalence.

Electrical Parameter Equivalence: The substitute part maintains all critical electrical specifications including contact form, current rating, coil voltage, and switching voltage limits. Minor variations in coil current (46.7 mA vs. 60 mA) and must-operate voltage (2.25 VDC vs. 2.1 VDC) remain within acceptable operational margins for general purpose relay applications.

Mechanical Compatibility: Through-hole mounting and PC pin termination are identical, ensuring direct PCB footprint compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can V23079B1208B301 be used as a direct replacement for DS2Y-SL2-DC3V?

A: Yes. The substitute part meets all mandatory electrical and mechanical parameters: identical DPDT contact form, 2A current rating, 3VDC coil voltage, latching dual-coil operation, through-hole mounting, and PC pin termination. No circuit redesign or PCB modification is required.

Q: What are the differences in coil current between the main part and substitute?

A: The DS2Y-SL2-DC3V operates at 60 mA coil current, while the V23079B1208B301 operates at 46.7 mA. The substitute part requires lower coil drive current, which may reduce power consumption in the control circuit. Existing drive circuits designed for 60 mA will operate the substitute part without issue.

Q: Are there differences in operating voltage requirements?

A: The must-operate voltage differs slightly: DS2Y-SL2-DC3V requires 2.1 VDC minimum, while V23079B1208B301 requires 2.25 VDC minimum. Both specifications are satisfied by standard 3VDC supply circuits. The difference is negligible for applications with stable power supplies.

Q: Is the substitute part RoHS compliant?

A: The V23079B1208B301 is ROHS3 compliant. Both parts maintain REACH Unaffected status and identical EAR99 ECCN classification.

Q: What is the inventory status of the substitute part?

A: The V23079B1208B301 is currently in active production with 952 pieces available in new original stock, ensuring reliable supply availability compared to the obsolete DS2Y-SL2-DC3V.
