Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2Y-S-DC5V is determined by the following critical parameters:

Primary Matching Criteria:

• 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)

Secondary Compatibility Criteria:

• Contact rating: Minimum 2A (equal or higher acceptable)
• Switching voltage: Minimum 220VDC (equal or higher acceptable)
• Operating temperature range: Must encompass application requirements
• Coil current: Lower values indicate improved efficiency; higher values acceptable if circuit supports
• Operate/Release time: Timing-critical applications require close matching

Three substitute parts meet the primary matching criteria while maintaining functional compatibility within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

TX2-5V (Panasonic Electric Works)

This substitute is the preferred choice for new designs and ongoing production. It maintains identical coil voltage, contact form, and current rating as the original DS2Y-S-DC5V. The TX2-5V operates at lower coil current (28.1 mA versus 40 mA), reducing power consumption and heat generation. Product status is active, ensuring long-term availability and supply chain stability. RoHS3 compliance exceeds the original RoHS compliance requirement. Operating temperature range extends to 85°C, providing broader environmental tolerance. Sealed construction offers enhanced protection in industrial environments.

C93416 (TE Connectivity Potter & Brumfield Relays)

This substitute provides equivalent electrical performance with identical contact rating and switching voltage specifications. Coil resistance and current match the original part exactly. Operating temperature range extends to 85°C maximum, exceeding the original specification. Contact material composition differs (Silver Nickel versus pure Silver), which remains within acceptable substitution parameters for general purpose applications. Product status is obsolete; use only when TX2-5V is unavailable or when existing inventory must be consumed.

V23105A5301A201 (TE Connectivity Potter & Brumfield Relays)

This substitute provides enhanced current rating (3A versus 2A), suitable for applications requiring higher contact capacity. Coil specifications match the original part. Must release voltage is lower (0.25 VDC versus 0.5 VDC), enabling faster release in low-voltage conditions. Operating temperature range extends to 85°C. Product status is obsolete; consider this option only when higher current capacity is required and TX2-5V does not meet application demands.

Frequently Asked Questions (FAQ)

Q: Can TX2-5V directly replace DS2Y-S-DC5V in existing designs?

A: Yes. TX2-5V matches all primary electrical and mechanical parameters: 5VDC coil voltage, DPDT contact form, 2A contact rating, through-hole mounting, and PC pin termination. Lower coil current (28.1 mA) reduces power consumption without affecting switching performance. Verify circuit design accommodates the slightly higher must-operate voltage (3.75 VDC versus 4.6 VDC).

Q: What is the difference between the three substitute parts?

A: TX2-5V is the primary substitute with active product status and improved efficiency. C93416 provides equivalent performance but is obsolete. V23105A5301A201 offers higher current rating (3A) and faster release characteristics but is also obsolete. Selection depends on availability, current requirements, and release timing specifications.

Q: Are there packaging differences between these parts?

A: Yes. DS2Y-S-DC5V uses standard packaging. TX2-5V is supplied in tube packaging. C93416 is supplied in tube packaging. V23105A5301A201 is supplied in box packaging. Verify packaging compatibility with assembly equipment and inventory management systems.

Q: Does coil resistance variation affect circuit design?

A: Coil resistance differences (125 Ohms for DS2Y-S-DC5V, C93416, and V23105A5301A201 versus 178 Ohms for TX2-5V) result in different coil currents at the same voltage. TX2-5V draws 28.1 mA versus 40 mA for the original part. Verify power supply capacity and control circuit design accommodate these differences. Higher resistance reduces heat generation and improves efficiency.

Q: Which substitute is recommended for new production?

A: TX2-5V is the recommended choice for new designs. It is the only active product among the substitutes, ensuring long-term availability and supply chain continuity. It provides improved efficiency through lower coil current and extended operating temperature range. RoHS3 compliance meets current regulatory requirements.

Q: Are there temperature range limitations when substituting?

A: The original DS2Y-S-DC5V operates from -40°C to 70°C. TX2-5V, C93416, and V23105A5301A201 all extend the upper limit to 85°C. If the application operates above 70°C, verify that the original design specifications do not restrict operation to the narrower range. All substitutes are compatible with the original -40°C lower limit.

Q: What contact material differences exist?

A: DS2Y-S-DC5V uses Silver (Ag) and Gold (Au) contact materials. C93416 uses Silver Nickel (AgNi) and Gold (Au). V23105A5301A201 uses Silver Nickel (AgNi). These material variations remain within acceptable substitution parameters for general purpose relay applications. Contact material selection affects contact resistance and wear characteristics; verify compatibility with application switching frequency and load type.
