DS2Y-S-DC6V Equivalent & Substitute Parts

Part Overview

The DS2Y-S-DC6V is a general purpose relay manufactured by Panasonic Electric Works with DPDT (2 Form C) contact configuration, rated for 2A at 6VDC. This through-hole mounted relay features PC pin termination and operates across -40°C to 70°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS2Y-S-DC6V is determined by strict alignment of the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be DPDT (2 Form C) to maintain switching capability
• Contact Rating: Must support minimum 2A current rating
• Mounting Type: Must be through-hole to fit existing PCB layouts
• Termination Style: Must use PC pin configuration for direct socket compatibility
• Coil Type: Must be non-latching for equivalent operational behavior

The TX2-6V meets all substitution criteria. While it operates across an extended temperature range (-40°C to 85°C) and features sealed construction, these represent functional enhancements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The TX2-6V is a direct functional substitute for the DS2Y-S-DC6V. Both relays are manufactured by Panasonic Electric Works and share identical electrical and mechanical core specifications: 6VDC coil voltage, DPDT contact configuration, 2A current rating, through-hole mounting, and PC pin termination.

The TX2-6V offers the advantage of active product status, ensuring continued availability and supply chain reliability. It meets ROHS3 compliance, exceeding the RoHS compliance of the original part. The sealed construction of the TX2-6V provides enhanced environmental protection compared to the general purpose design of the DS2Y-S-DC6V.

Minor parameter differences exist: the TX2-6V operates across an extended temperature range (-40°C to 85°C versus -40°C to 70°C), draws lower coil current (23.3 mA versus 33.3 mA), and has slightly higher coil resistance (257 Ohms versus 180 Ohms). These differences do not affect substitution compatibility for applications within the original operating temperature specification.

Frequently Asked Questions (FAQ)

Q: Can the TX2-6V directly replace the DS2Y-S-DC6V in existing designs?

A: Yes. Both relays share identical coil voltage (6VDC), contact form (DPDT), current rating (2A), mounting type (through-hole), and termination style (PC pin). Direct socket substitution is possible without circuit modification.

Q: What is the significance of the product status difference?

A: The DS2Y-S-DC6V is obsolete, meaning Panasonic Electric Works no longer manufactures or supports this part. The TX2-6V is active, ensuring ongoing availability, technical support, and supply chain continuity for new procurements and system maintenance.

Q: How do the coil current differences affect circuit design?

A: The TX2-6V draws 23.3 mA compared to the DS2Y-S-DC6V at 33.3 mA. This lower coil current requirement in the TX2-6V reduces power consumption and heat generation. Existing driver circuits designed for the DS2Y-S-DC6V will operate the TX2-6V without modification, as the lower current demand is within the design margin of standard relay driver circuits.

Q: Are there environmental or reliability differences between these relays?

A: The TX2-6V features sealed construction and operates across an extended temperature range (-40°C to 85°C versus -40°C to 70°C). These characteristics provide enhanced environmental protection and broader operational capability. Both relays maintain identical contact material composition (Silver and Gold) and moisture sensitivity level (MSL 1).

Q: What packaging considerations apply to the TX2-6V?

A: The TX2-6V is supplied in tube packaging, whereas the DS2Y-S-DC6V packaging format is not specified in available documentation. Both use identical through-hole PC pin termination, ensuring compatibility with standard PCB assembly processes and existing socket designs.
