DS2E-S-DC5V Equivalent & Substitute Parts

Part Overview

The DS2E-S-DC5V is a general purpose DPDT relay manufactured by Panasonic Electric Works with a 5VDC coil, rated for 2A switching current. This through-hole mounted relay features sealed construction and is designed for general purpose switching applications. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where similar functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS2E-S-DC5V are selected based on the following critical parameters that must match or exceed the original specification:

Core Compatibility Requirements:

• Coil voltage: 5VDC (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)

Allowable Parameter Variations:

• Contact rating current: Equal to or greater than 2A
• Switching voltage: Equal to or greater than 250VAC/220VDC
• Coil current: Lower values acceptable (reduced power consumption)
• Operating temperature range: Equal to or wider than -40°C ~ 70°C
• Operate/Release time: Variations acceptable within application timing requirements

Three substitute parts meet these criteria: TX2-5V (Panasonic), C93416 (TE Connectivity), and V23105A5301A201 (TE Connectivity).

Parameter Comparison

Engineering Selection Recommendations

TX2-5V (Panasonic Electric Works) - Preferred Substitute

The TX2-5V is the recommended primary substitute. It maintains identical coil voltage, contact form, current rating, and mounting configuration as the DS2E-S-DC5V. The TX2-5V is currently in active production status, ensuring long-term availability. It features improved coil efficiency (28.1 mA versus 40 mA), faster switching response times (4 ms operate and release), and an extended operating temperature range (-40°C ~ 85°C). ROHS3 compliance provides enhanced environmental standards. The only parameter reduction is switching voltage (220VDC maximum versus 250VAC/220VDC), which remains adequate for most general purpose applications.

C93416 (TE Connectivity Potter & Brumfield Relays) - Alternative Substitute

The C93416 provides electrical equivalence with identical coil voltage, contact form, current rating, and coil current specifications. It maintains the full switching voltage capability (250VAC/220VDC) of the original part. The extended operating temperature range (-55°C ~ 85°C) exceeds the original specification. However, this part is obsolete, limiting future availability. ROHS3 compliance is provided.

V23105A5301A201 (TE Connectivity Potter & Brumfield Relays) - Higher Current Rating Alternative

The V23105A5301A201 offers a higher contact current rating (3A versus 2A), providing additional switching capacity. It maintains coil voltage, contact form, and mounting specifications. The operating temperature range (-40°C ~ 85°C) exceeds the original. This part is obsolete and should be considered only when the higher current rating provides specific system benefits.

Frequently Asked Questions (FAQ)

Q: Can TX2-5V directly replace DS2E-S-DC5V in existing designs?

A: Yes. The TX2-5V maintains identical coil voltage (5VDC), contact form (DPDT), current rating (2A), mounting type (through hole), and termination style (PC pin). The reduced switching voltage specification (220VDC maximum versus 250VAC/220VDC) is acceptable for general purpose applications not requiring the full 250VAC capability. Faster switching times (4 ms versus 10 ms operate time) may require timing verification in time-critical circuits.

Q: What is the primary advantage of TX2-5V over the original DS2E-S-DC5V?

A: The TX2-5V is in active production, ensuring availability for future orders and maintenance. It also provides lower coil current consumption (28.1 mA versus 40 mA), reducing power supply requirements, and faster switching response times.

Q: Are C93416 and V23105A5301A201 suitable for new designs?

A: Both parts are obsolete. While they provide electrical compatibility, their discontinued status makes them unsuitable for new designs requiring long-term component availability. TX2-5V is the recommended choice for new applications.

Q: Does packaging differ between substitute parts?

A: Yes. DS2E-S-DC5V uses standard packaging, TX2-5V is supplied in tube packaging, C93416 is supplied in tube packaging, and V23105A5301A201 is supplied in box packaging. Verify packaging compatibility with assembly equipment and procurement processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. DS2E-S-DC5V is RoHS Compliant, while TX2-5V, C93416, and V23105A5301A201 are ROHS3 Compliant or RoHS Compliant, meeting environmental regulatory requirements.

Q: What is the impact of different coil resistance values?

A: TX2-5V has 178 Ohms coil resistance versus 125 Ohms in the original. This higher resistance results in lower coil current (28.1 mA versus 40 mA) and is compatible with standard 5VDC power supplies. Verify that existing drive circuits can accommodate the different resistance value if precise current control is required.
