Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC4ED-PL-DC100V is determined by the following critical parameters:

Contact Configuration: The 4PDT (4 Form C) contact form is mandatory for functional equivalence, as it provides four independent switching circuits required by the original design.

Coil Voltage Class: The 100VDC coil voltage establishes the control signal requirement. Substitutes within the 100-110VDC range are acceptable based on standard industrial relay voltage tolerance specifications.

Contact Rating: The 1A contact current rating defines the maximum load-switching capability. Substitutes with equal or higher current ratings (3A or greater) maintain backward compatibility.

Switching Voltage: The 250VAC maximum switching voltage specification must be met or exceeded by substitute components.

Mounting and Termination: Through-hole mounting with PC pin termination is required for direct board-level compatibility.

Coil Type: Non-latching operation is essential for applications requiring continuous coil energization to maintain contact closure.

The MY4-02-DC100/110 from Omron Automation and Safety meets all substitution criteria within these parameters.

Engineering Selection Recommendations

The MY4-02-DC100/110 is the qualified substitute for the HC4ED-PL-DC100V based on the following engineering criteria:

Functional Compatibility: Both relays provide identical 4PDT contact configuration and non-latching coil operation, ensuring direct functional replacement in existing circuit designs.

Coil Voltage Alignment: The 110VDC coil voltage of the MY4-02-DC100/110 is within standard industrial tolerance of the original 100VDC specification, with must-operate and must-release voltages (88VDC and 11VDC respectively) compatible with typical control circuit designs.

Enhanced Contact Rating: The MY4-02-DC100/110 provides 3A contact rating compared to the original 1A rating, offering improved margin for load-switching applications without requiring circuit redesign.

Active Product Status: The MY4-02-DC100/110 is currently in active production, ensuring long-term availability and supply chain continuity for new designs and ongoing maintenance requirements.

Compliance and Certification: Both components share identical ECCN (EAR99) and HTSUS (8536.49.0050) classifications. The MY4-02-DC100/110 carries RoHS compliance certification, meeting modern regulatory requirements.

Thermal Performance: The MY4-02-DC100/110 extends the operating temperature range to -55°C ~ 70°C, providing broader environmental compatibility compared to the original -40°C ~ 60°C range.

Frequently Asked Questions (FAQ)

Q: Can the MY4-02-DC100/110 directly replace the HC4ED-PL-DC100V without circuit modification?

A: Yes. Both relays share identical 4PDT contact configuration, PC pin termination, through-hole mounting, and 20ms operate/release timing. The 110VDC coil voltage is within standard industrial tolerance of the 100VDC original specification.

Q: What is the significance of the higher 3A contact rating on the MY4-02-DC100/110?

A: The MY4-02-DC100/110 provides 3A contact rating versus the original 1A rating. This represents increased load-switching capacity and is backward compatible with applications originally designed for 1A operation. No circuit modification is required.

Q: Are there packaging differences between these relays?

A: The HC4ED-PL-DC100V uses standard through-hole PC pin termination. The MY4-02-DC100/110 is supplied in bulk packaging and maintains identical through-hole PC pin termination, ensuring mechanical and electrical compatibility on printed circuit boards.

Q: How do the coil current specifications compare?

A: The MY4-02-DC100/110 draws 9.1mA compared to the original 11mA. This lower coil current reduces control circuit power consumption while maintaining identical switching performance and timing characteristics.

Q: What compliance advantages does the MY4-02-DC100/110 offer?

A: The MY4-02-DC100/110 is RoHS compliant and carries active product status, ensuring compliance with modern environmental regulations and long-term component availability for new system designs and maintenance applications.
