DS2Y-S-DC12V-R Equivalent & Substitute Parts

Part Overview

The DS2Y-S-DC12V-R is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 2A contact rating and 12VDC coil voltage. This through-hole mounted relay is designed for general purpose switching applications with non-latching coil operation and reverse polarity protection.

The DS2Y-S-DC12V-R is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS2Y-S-DC12V-R are identified based on the following critical parameters that determine functional compatibility:

• Coil Voltage: 12VDC (exact match required)
• Contact Form: DPDT (2 Form C) (exact match required)
• Coil Resistance: 720 Ohms (exact match required)
• Termination Style: PC Pin (exact match required)
• Mounting Type: Through Hole (exact match required)
• Coil Type: Non Latching (exact match required)

The identified substitute parts meet these core electrical and mechanical parameters. Variations in contact rating (current capacity), operating temperature range, and switching voltage specifications are noted in the parameter comparison table below.

Engineering Selection Recommendations

C93418 (TE Connectivity Potter & Brumfield Relays)

The C93418 is a direct functional equivalent with identical contact rating (2A), coil resistance (720 Ohms), and switching specifications. This substitute maintains the same electrical performance envelope as the DS2Y-S-DC12V-R. The C93418 offers an extended operating temperature range (-55°C ~ 85°C) compared to the original part. Both parts are classified as obsolete with REACH Unaffected status and EAR99 ECCN classification.

V23105A5303A201 (TE Connectivity Potter & Brumfield Relays)

The V23105A5303A201 is a higher-rated substitute with 3A contact capacity versus the original 2A rating. This part shares identical coil voltage, resistance, and contact form specifications. The V23105A5303A201 features improved must-release voltage (0.6 VDC versus 1.2 VDC) and an extended operating temperature range (-40°C ~ 85°C). This part is RoHS Compliant, providing enhanced environmental compliance compared to the original obsolete part. Selection of this substitute is appropriate for applications requiring higher contact current capacity or improved environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can C93418 be used as a direct replacement for DS2Y-S-DC12V-R?

A: Yes. The C93418 maintains identical coil voltage (12VDC), contact form (DPDT), contact rating (2A), coil resistance (720 Ohms), and termination style (PC Pin). Both parts are through-hole mounted with non-latching coil operation. The C93418 provides equivalent electrical performance with an extended operating temperature range.

Q: What is the primary difference between C93418 and V23105A5303A201?

A: The V23105A5303A201 has a higher contact rating (3A versus 2A). Both parts share the same coil specifications (12VDC, 720 Ohms, 16.7 mA). The V23105A5303A201 also features improved must-release voltage (0.6 VDC) and RoHS compliance status.

Q: Should I select V23105A5303A201 if my application only requires 2A switching capacity?

A: The V23105A5303A201 is suitable for applications requiring 2A or less. The higher contact rating provides additional margin and does not negatively impact performance at lower current levels. Selection depends on design requirements, compliance mandates, and supply availability.

Q: Are there packaging differences between these substitutes?

A: Yes. The DS2Y-S-DC12V-R uses standard packaging. The C93418 is supplied in tube packaging, while the V23105A5303A201 is supplied in box packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: What is the operating temperature consideration when selecting a substitute?

A: The original DS2Y-S-DC12V-R operates from -40°C to 70°C. The C93418 extends this range to -55°C ~ 85°C, and the V23105A5303A201 to -40°C ~ 85°C. Select the substitute that matches or exceeds your application's temperature requirements.

Q: Are these substitutes suitable for legacy system repairs?

A: Both substitutes are classified as obsolete, consistent with the original part status. All three parts share REACH Unaffected status and EAR99 ECCN classification. Verify compliance requirements for your specific application and region before final selection.
