Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSBT2-M-2D-DC1.5V is determined by the following critical parameters:

• Coil Voltage: Must be 1.5VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be DPDT (2 Form D) to maintain switching functionality
• Contact Rating (Current): Must be rated for 1 A minimum to handle specified load currents
• Mounting Type: Must be Through Hole to fit existing PCB layouts
• Termination Style: Must be PC Pin for direct connection compatibility
• Coil Type: Must be Non Latching to match operational behavior
• Contact Material: Must include Silver (Ag) and Gold (Au) for electrical performance consistency

The TXD2-2M-1.5V meets all substitution criteria across these parameters, qualifying it as a direct equivalent for the obsolete DSBT2-M-2D-DC1.5V.

Parameter Comparison

Engineering Selection Recommendations

The TXD2-2M-1.5V is the qualified substitute for the obsolete DSBT2-M-2D-DC1.5V. Both relays are manufactured by Panasonic Electric Works and share identical electrical specifications across all critical switching and coil parameters.

The TXD2-2M-1.5V offers the advantage of active product status, ensuring ongoing availability and supply chain support. The substitute part features an extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 60°C) and sealed construction, providing enhanced environmental protection. Both parts carry identical export classification (EAR99) and tariff codes (8536.41.0020), with MSL rating of 1 (Unlimited).

The TXD2-2M-1.5V is RoHS Compliant, supporting modern regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the TXD2-2M-1.5V be used as a direct replacement for the DSBT2-M-2D-DC1.5V?

A: Yes. Both relays share identical coil voltage (1.5VDC), contact form (DPDT), current rating (1A), mounting type (Through Hole), and termination style (PC Pin). All critical electrical parameters match, including must-operate and must-release voltages.

Q: What are the differences between these two relays?

A: The primary differences are product status and environmental specifications. The TXD2-2M-1.5V is an active product with an extended operating temperature range (-40°C ~ 85°C) and sealed construction, compared to the obsolete DSBT2-M-2D-DC1.5V (-40°C ~ 60°C). The TXD2-2M-1.5V also carries RoHS Compliance certification.

Q: Are there packaging differences?

A: The DSBT2-M-2D-DC1.5V uses standard packaging, while the TXD2-2M-1.5V is supplied in Tube packaging. Both are through-hole mounted components with PC Pin termination suitable for PCB assembly.

Q: Do these relays have different coil currents?

A: Yes. The DSBT2-M-2D-DC1.5V draws 360 mA coil current with 4.2 Ohms coil resistance, while the TXD2-2M-1.5V draws 167 mA with 9 Ohms coil resistance. Both meet the 1.13 VDC must-operate voltage requirement. The lower coil current of the substitute may reduce power consumption in the application circuit.

Q: What is the switching voltage rating difference?

A: The DSBT2-M-2D-DC1.5V is rated for 250VAC and 220VDC maximum switching voltage, while the TXD2-2M-1.5V is rated for 110VDC maximum. Verify that your application switching voltage does not exceed 110VDC when using the substitute part.

Q: Are the operate and release times identical?

A: No. The DSBT2-M-2D-DC1.5V operates in 3 ms and releases in 2 ms, while the TXD2-2M-1.5V operates in 4 ms and releases in 4 ms. Applications with strict timing requirements should account for these differences.
