DS2E-S-DC12V Equivalent & Substitute Parts

Part Overview

The DS2E-S-DC12V is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 2A contact rating and 12VDC coil voltage. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The relay is designed for through-hole mounting with sealed construction and operates across -40°C to 70°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-S-DC12V is determined by the following critical parameters:

Primary Matching Criteria:

• Coil voltage: 12VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)

Secondary Compatibility Criteria:

• Contact rating: minimum 2A (equal or higher acceptable)
• Switching voltage: minimum 220VDC (equal or higher acceptable)
• Coil type: Non Latching (exact match required)
• Seal rating: Sealed - Fully (exact match required)

Three substitute parts meet these criteria: TX2-12V (Panasonic Electric Works), C93418 (TE Connectivity Potter & Brumfield Relays), and V23105A5303A201 (TE Connectivity Potter & Brumfield Relays).

Parameter Comparison

Engineering Selection Recommendations

TX2-12V is the preferred substitute for new designs and ongoing production. This part is manufactured by Panasonic Electric Works (same manufacturer as the original), maintains active product status, and achieves ROHS3 compliance. The TX2-12V demonstrates improved performance characteristics with faster operate and release times (4 ms each) and lower coil current (11.7 mA versus 16.7 mA), reducing power consumption. The higher coil resistance (1.03 kOhms) provides better noise immunity in switching applications. Operating temperature range extends to 85°C, exceeding the original specification.

C93418 serves as an alternative substitute when TX2-12V availability is constrained. Manufactured by TE Connectivity Potter & Brumfield Relays, this part matches the original coil resistance and coil current specifications exactly. The extended operating temperature range (-55°C to 85°C) accommodates more demanding thermal environments. However, C93418 carries obsolete product status, limiting long-term supply assurance.

V23105A5303A201 is suitable only for applications requiring contact ratings exceeding 2A. This part provides 3A contact rating and improved must-release voltage specification (0.6 VDC versus 1.2 VDC). The higher contact rating introduces design margin for current-intensive switching applications. Obsolete status and unspecified seal rating restrict its use to legacy system maintenance where exact replacement is necessary.

Frequently Asked Questions (FAQ)

Q: Can TX2-12V directly replace DS2E-S-DC12V in existing designs?

A: Yes. TX2-12V matches all critical substitution parameters: 12VDC coil voltage, DPDT contact form, 2A contact rating, through-hole mounting, and PC pin termination. The improved performance characteristics (faster switching times, lower coil current) are compatible with existing circuit designs. Verify PCB footprint compatibility before implementation.

Q: What is the primary difference between C93418 and TX2-12V?

A: Both parts meet substitution criteria. C93418 is manufactured by TE Connectivity and maintains identical coil resistance and current specifications to the original DS2E-S-DC12V. TX2-12V is manufactured by Panasonic Electric Works with active product status, lower coil current consumption, and faster switching response. TX2-12V is recommended for new designs due to active availability.

Q: Why does V23105A5303A201 have a higher contact rating (3A)?

A: V23105A5303A201 is designed for telecom applications requiring higher contact current capacity. The 3A rating provides design margin for applications exceeding 2A switching requirements. This part is suitable only when contact rating upgrade is necessary; it is not required for direct replacement of 2A-rated circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. DS2E-S-DC12V is RoHS Compliant. TX2-12V and C93418 are ROHS3 Compliant. V23105A5303A201 is RoHS Compliant. All parts meet current environmental compliance requirements.

Q: What packaging differences exist among these parts?

A: DS2E-S-DC12V is supplied in standard packaging. TX2-12V and C93418 are packaged in tubes. V23105A5303A201 is packaged in boxes. Packaging format does not affect electrical or mechanical compatibility; verify reel or tube specifications for automated assembly processes.

Q: Can these parts be used interchangeably in high-temperature applications?

A: TX2-12V and C93418 extend operating temperature to 85°C, suitable for elevated-temperature environments. C93418 reaches -55°C minimum, providing the widest thermal range. DS2E-S-DC12V is limited to 70°C maximum. Select substitute parts based on specific thermal requirements.
