DS2Y-SL2-DC9V Equivalent & Substitute Parts

Part Overview

The DS2Y-SL2-DC9V is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) with a 9VDC coil and 2A contact rating. This through-hole mounted relay is designed for switching applications up to 250VAC or 220VDC. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS2Y-SL2-DC9V are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable operating ranges:

• Contact form configuration: DPDT (2 Form C)
• Coil voltage: 9VDC
• Contact current rating: 2 A minimum
• Switching voltage capability: 250VAC, 220VDC or higher
• Coil type: Latching, Dual Coil
• Mounting type: Through Hole
• Termination style: PC Pin

The V23079B1206B301 from TE Connectivity Potter & Brumfield Relays meets all these criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1206B301 is the qualified substitute for the obsolete DS2Y-SL2-DC9V. Selection is based on the following factors:

Electrical compatibility is confirmed through matching contact form (DPDT), coil voltage (9VDC), contact current rating (2A), and switching voltage capability (250VAC, 220VDC). The substitute operates at a lower coil current (15.6 mA versus 20 mA), which reduces power consumption without compromising switching performance.

Mechanical compatibility is established through identical mounting type (through hole) and termination style (PC pin), ensuring direct board-level substitution without redesign.

The V23079B1206B301 holds active product status with RoHS compliance certification, providing long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1206B301 be used as a direct replacement for the DS2Y-SL2-DC9V?

A: Yes. Both relays share identical contact form (DPDT), coil voltage (9VDC), contact rating (2A), switching voltage (250VAC, 220VDC), coil type (latching dual coil), mounting type (through hole), and termination style (PC pin). The substitute operates at lower coil current and higher must-operate voltage, both within acceptable system design margins.

Q: What is the difference in coil current between these relays?

A: The DS2Y-SL2-DC9V requires 20 mA coil current, while the V23079B1206B301 requires 15.6 mA. The lower current in the substitute reduces power consumption and heat generation without affecting switching performance or contact ratings.

Q: Are there packaging differences between these parts?

A: The DS2Y-SL2-DC9V uses standard through-hole packaging. The V23079B1206B301 is supplied in tube packaging. Both maintain identical PC pin termination and board-level footprint compatibility.

Q: What is the must-operate voltage difference?

A: The DS2Y-SL2-DC9V must operate at 6.3 VDC minimum, while the V23079B1206B301 requires 6.75 VDC minimum. In applications where coil voltage is maintained at or above 9VDC nominal, this difference does not affect relay operation.

Q: Is the substitute RoHS compliant?

A: Yes. The V23079B1206B301 is RoHS compliant. The original DS2Y-SL2-DC9V RoHS status is not specified in available documentation.
