DS2E-S-DC48V Equivalent & Substitute Parts

Part Overview

The DS2E-S-DC48V is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 48VDC coil voltage and 2A contact rating. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The relay operates with non-latching coil type and is sealed for environmental protection, suitable for through-hole PCB mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS2E-S-DC48V is determined by strict alignment of the following critical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Coil Current: 4.2 mA (exact match required)
• Coil Resistance: 11.52 kOhms (exact match required)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Must Operate Voltage: 33.6 VDC minimum
• Switching Voltage: 250VAC, 220VDC maximum

The V23105A5307A201 qualifies as a substitute part because it maintains identical coil voltage, coil current, coil resistance, contact form, mounting type, and termination style. While the contact rating differs (3A versus 2A), this represents an upgrade in capability and does not compromise compatibility in applications designed for 2A operation.

Parameter Comparison

Engineering Selection Recommendations

Both the DS2E-S-DC48V and V23105A5307A201 are classified as obsolete products. Selection between these parts should be based on the following criteria:

DS2E-S-DC48V remains the original specification part for legacy system maintenance where exact component matching is required for documentation and traceability purposes.

V23105A5307A201 serves as the substitute part for new designs or system upgrades. This part provides enhanced performance characteristics including higher contact rating (3A), faster switching times (6ms operate, 4ms release versus 10ms and 5ms), and extended operating temperature range (-40°C to 85°C). Both parts maintain RoHS compliance and identical electrical drive characteristics (4.2mA coil current, 11.52kOhms coil resistance).

The substitute part's higher current rating and improved timing characteristics make it suitable for applications where the original 2A rating was marginal or where faster switching response is beneficial.

Frequently Asked Questions (FAQ)

Q: Can V23105A5307A201 directly replace DS2E-S-DC48V in existing circuits?

A: Yes. Both relays share identical coil voltage (48VDC), coil current (4.2mA), coil resistance (11.52kOhms), contact form (DPDT), and switching voltage specifications. The substitute part's 3A contact rating is compatible with applications designed for 2A operation. Physical mounting and termination are identical (through-hole PC pins).

Q: What are the key differences between these parts?

A: The V23105A5307A201 provides three enhancements: higher contact current rating (3A versus 2A), faster switching response (6ms operate and 4ms release versus 10ms and 5ms), and extended operating temperature range (-40°C to 85°C versus -40°C to 70°C). Coil drive requirements remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both DS2E-S-DC48V and V23105A5307A201 are RoHS compliant and carry EAR99 ECCN classification.

Q: Why is the DS2E-S-DC48V marked obsolete?

A: Panasonic Electric Works has discontinued this product line. The V23105A5307A201 represents the current equivalent from TE Connectivity Potter & Brumfield Relays for applications requiring 48VDC DPDT relay functionality.

Q: Will the faster switching times of V23105A5307A201 affect circuit operation?

A: Faster switching times (6ms operate, 4ms release) represent an improvement and will not negatively affect circuits designed for the original 10ms and 5ms specifications. Applications sensitive to switching timing should verify compatibility with the faster response characteristics.

Q: Are there packaging differences between these parts?

A: DS2E-S-DC48V is supplied in standard packaging, while V23105A5307A201 is supplied in box packaging. Both are through-hole components with identical PC pin termination suitable for PCB mounting.
