DS2E-S-DC3V Equivalent & Substitute Parts

Part Overview

The DS2E-S-DC3V is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) switch with 2A contact rating and 3VDC coil voltage. This through-hole mounted relay is designed for general purpose switching applications with sealed construction and silver/gold contact materials.

The DS2E-S-DC3V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2E-S-DC3V is determined by the following critical parameters:

• Coil voltage must be 3VDC
• Contact form must be DPDT (2 Form C)
• Contact rating must be 2 A minimum
• Mounting type must be through hole with PC pin termination
• Coil type must be non-latching
• Seal rating must be fully sealed
• Contact material must include silver and/or gold
• Operating temperature range must encompass or exceed the application requirements

The TX2-3V meets all substitution criteria. While classified as a telecom relay rather than general purpose, it maintains electrical and mechanical compatibility with the DS2E-S-DC3V across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The TX2-3V is a direct electrical and mechanical substitute for the DS2E-S-DC3V. Both relays are manufactured by Panasonic Electric Works and share identical coil voltage, contact form, current rating, mounting configuration, and termination style.

The TX2-3V offers the following advantages:

• Active product status with current manufacturing and supply availability
• ROHS3 compliance, exceeding the RoHS compliance of the DS2E-S-DC3V
• Extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C)
• Lower coil current requirement (46.7 mA versus 66.7 mA)
• Faster switching response (4 ms operate and release time versus 10 ms and 5 ms)

The TX2-3V switching voltage specification (220VDC maximum) is lower than the DS2E-S-DC3V (250VAC, 220VDC maximum). Applications requiring 250VAC switching capability must evaluate this parameter against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the TX2-3V replace the DS2E-S-DC3V in all applications?

A: The TX2-3V is electrically and mechanically compatible with the DS2E-S-DC3V for applications operating within the specified parameters of both relays. The primary consideration is the switching voltage specification. The DS2E-S-DC3V supports 250VAC switching, while the TX2-3V is rated for 220VDC maximum. Applications requiring 250VAC switching capability must confirm compatibility with the TX2-3V specification.

Q: What are the key differences between these relays?

A: Both relays share identical coil voltage (3VDC), contact form (DPDT), current rating (2A), and mounting configuration (through-hole PC pin). The TX2-3V operates faster (4 ms versus 5-10 ms), draws less coil current (46.7 mA versus 66.7 mA), and supports a wider operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). The TX2-3V has a lower maximum switching voltage specification (220VDC versus 250VAC/220VDC).

Q: Why is the DS2E-S-DC3V classified as obsolete?

A: The DS2E-S-DC3V is no longer in active production. The TX2-3V represents the current equivalent offering from Panasonic Electric Works with improved performance characteristics and active supply availability.

Q: Are there packaging differences between these relays?

A: The DS2E-S-DC3V is supplied in standard packaging, while the TX2-3V is supplied in tube packaging. Both use identical through-hole PC pin termination suitable for PCB mounting.

Q: Do both relays meet current compliance standards?

A: The DS2E-S-DC3V is RoHS Compliant. The TX2-3V is ROHS3 Compliant, representing a more current compliance standard. Both relays are classified as EAR99 for export control purposes.
