HC4-HPL-AC100V Equivalent & Substitute Parts

Part Overview

The HC4-HPL-AC100V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 100VAC coil. This through-hole mounted relay is designed for applications requiring multiple independent switching circuits with a 5A contact rating at 250VAC maximum switching voltage. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC4-HPL-AC100V is determined by the following critical parameters:

Contact configuration must remain 4PDT (4 Form C) to maintain circuit topology compatibility. Coil voltage must operate within the system's AC supply range; the HC4-HPL-AC100V operates at 100VAC with a must-operate threshold of 80VAC and must-release threshold of 30VAC. Contact current rating must meet or exceed the application's switching requirements; the original part is rated at 5A. Switching voltage capability must support the maximum voltage present in the controlled circuits, with the original part rated to 250VAC maximum. Mounting type must be through-hole to ensure PCB compatibility. Termination style must be PC pin for direct board insertion. Coil type must remain non-latching for standard relay operation. Operating temperature range must encompass the application environment.

The MY4-02-AC100/110 from Omron Automation and Safety qualifies as a substitute based on matching contact form (4PDT), mounting type (through-hole), termination style (PC pin), coil type (non-latching), and operating time/release time specifications (20 ms each). The coil voltage of 110VAC is compatible with 100VAC system designs, as the must-operate voltage of 88VAC and must-release voltage of 33VAC remain within acceptable operating margins relative to the original part's thresholds.

Parameter Comparison

Engineering Selection Recommendations

The MY4-02-AC100/110 is an active product with RoHS compliance certification, providing supply chain continuity for applications currently using the obsolete HC4-HPL-AC100V. Both relays share identical contact form, mounting configuration, and switching timing characteristics.

The primary design consideration is the contact current rating differential: the HC4-HPL-AC100V is rated at 5A while the MY4-02-AC100/110 is rated at 3A. Applications requiring switching currents exceeding 3A cannot use the Omron substitute without circuit redesign. The coil voltage difference of 10VAC (100VAC versus 110VAC) is within acceptable tolerance for standard AC supply systems, with both relays maintaining proper operation within their specified must-operate and must-release voltage ranges.

The MY4-02-AC100/110 provides an extended operating temperature range (-55°C to 70°C versus -50°C to 60°C), offering improved performance in extreme temperature environments. The Omron relay's contact material composition differs (Silver versus Silver Nickel/Gold), which may affect performance in specific chemical or corrosive environments; application-specific environmental requirements should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the MY4-02-AC100/110 directly replace the HC4-HPL-AC100V in all applications?

A: Direct replacement is possible only in applications where the contact switching current does not exceed 3A. The HC4-HPL-AC100V is rated for 5A, while the MY4-02-AC100/110 is rated for 3A. If your application requires switching currents between 3A and 5A, the Omron relay cannot be used as a substitute.

Q: Is the 10VAC coil voltage difference (100VAC versus 110VAC) acceptable?

A: Yes. Both relays operate within their specified must-operate and must-release voltage ranges when supplied with standard AC power. The HC4-HPL-AC100V operates at 80VAC minimum and 30VAC maximum release threshold. The MY4-02-AC100/110 operates at 88VAC minimum and 33VAC maximum release threshold. Both specifications are compatible with typical AC supply systems.

Q: What are the physical compatibility considerations?

A: Both relays use through-hole mounting with PC pin termination, ensuring identical PCB footprint compatibility. No physical modifications to the circuit board are required for substitution.

Q: How do the contact materials differ, and does this affect performance?

A: The HC4-HPL-AC100V uses Silver Nickel (AgNi) and Gold (Au) contact materials, while the MY4-02-AC100/110 uses Silver (Ag). Contact material selection affects performance in specific environments such as high-humidity, corrosive, or high-frequency switching applications. Evaluate your application's environmental conditions before substitution.

Q: Does the MY4-02-AC100/110 meet RoHS compliance requirements?

A: Yes, the MY4-02-AC100/110 is RoHS compliant. The HC4-HPL-AC100V's RoHS status is not specified in the available documentation.

Q: Are the switching timing characteristics identical?

A: Yes. Both relays have identical operate time and release time specifications of 20 ms, ensuring equivalent switching performance in timing-critical applications.
