DS2E-S-DC9V Equivalent & Substitute Parts

Part Overview

The DS2E-S-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 general purpose switching applications with sealed construction and PC pin termination. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-S-DC9V is determined by the following critical parameters:

• Coil Voltage: Must be 9VDC
• Contact Form: Must be DPDT (2 Form C)
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin
• Coil Type: Must be Non Latching
• Seal Rating: Must be Sealed - Fully

The identified substitute parts meet these core requirements. Variations in contact rating (2A vs. 3A), coil current, operate/release times, and operating temperature ranges represent acceptable differences for substitution purposes, as these parameters do not prevent functional compatibility in applications designed for the DS2E-S-DC9V.

Engineering Selection Recommendations

TX2-9V is the preferred substitute for new designs and ongoing production applications. This part is manufactured by Panasonic Electric Works (same manufacturer as the main part), maintains active product status, and carries ROHS3 compliance. The TX2-9V demonstrates improved performance characteristics with faster operate and release times (4 ms each) and an extended operating temperature range (-40°C ~ 85°C). Lower coil current (15.5 mA) reduces power consumption. The contact rating of 2A matches the original specification exactly.

V23105A5306A201 is an alternative substitute suitable for applications where higher contact rating (3A) is beneficial or where TE Connectivity sourcing is preferred. This part maintains the same coil resistance (405 Ohms) and coil current (22.2 mA) as the original DS2E-S-DC9V, ensuring identical electrical load characteristics. However, this part is obsolete and should be considered only when TX2-9V availability is constrained. The extended operating temperature range (-40°C ~ 85°C) provides additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can TX2-9V directly replace DS2E-S-DC9V in existing circuits?

A: Yes. Both parts share identical coil voltage (9VDC), contact form (DPDT), contact rating (2A), mounting type (through hole), and termination style (PC pin). The faster switching times of TX2-9V (4 ms operate/release vs. 10 ms/5 ms) are compatible with applications designed for the original part.

Q: What is the difference between TX2-9V and V23105A5306A201?

A: TX2-9V is a Panasonic Electric Works telecom relay with 2A contact rating and active product status. V23105A5306A201 is a TE Connectivity telecom relay with 3A contact rating and obsolete status. Both are functionally compatible with DS2E-S-DC9V, but TX2-9V is recommended for new applications due to active availability.

Q: Does the higher contact rating of V23105A5306A201 (3A vs. 2A) affect compatibility?

A: No. A higher contact rating indicates the part can safely handle greater current loads. Applications designed for 2A operation remain fully compatible with a 3A-rated contact.

Q: Are there packaging differences between these substitutes?

A: DS2E-S-DC9V packaging is not specified in the provided data. TX2-9V and V23105A5306A201 are both supplied in tube packaging. Verify packaging requirements for your specific procurement process.

Q: How do the operating temperature ranges compare?

A: DS2E-S-DC9V operates from -40°C to 70°C. Both TX2-9V and V23105A5306A201 extend this range to -40°C to 85°C, providing additional thermal margin for applications in elevated temperature environments.

Q: What is the significance of the different coil currents?

A: DS2E-S-DC9V and V23105A5306A201 both draw 22.2 mA at 9VDC. TX2-9V draws 15.5 mA, resulting in lower power consumption and reduced heat generation. This difference is due to higher coil resistance (579 Ohms vs. 405 Ohms) and does not affect functional compatibility.
