HC2-H-AC240V-F Equivalent & Substitute Parts

Part Overview

The HC2-H-AC240V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 240VAC coil voltage and 7A contact rating. This socketable relay is designed for general industrial switching applications. The product is currently obsolete, making equivalent and substitute parts necessary for system maintenance, repair, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC2-H-AC240V-F is determined by the following critical parameters:

• Coil Voltage: 240VAC (acceptable range: 192VAC minimum operate voltage to 250VAC maximum switching voltage)
• Contact Form: DPDT (2 Form C) configuration required
• Mounting Type: Socketable with Plug In termination
• Coil Type: Non Latching operation
• Contact Material: Silver-based alloys (Silver Alloy, Silver, or Silver Nickel)

Substitute parts are grouped into two categories:

Direct Substitutes meet all critical parameters with contact ratings at or above 5A and operating temperature ranges compatible with the original specification.

Similar Substitutes meet all critical parameters but may have higher contact ratings (10A, 12A) or slightly different operating temperature ranges, suitable for applications where the original 7A rating provides adequate margin.

Parameter Comparison

Engineering Selection Recommendations

MY2 AC220/240 (S) is the primary direct substitute. It maintains the 240VAC coil voltage, DPDT contact form, socketable mounting, and plug-in termination. The 5A contact rating is lower than the original 7A specification; this substitute is suitable for applications where the load current does not exceed 5A. The part is RoHS Compliant and currently in active production status, ensuring long-term availability.

LY2-AC220/240 is a similar substitute with higher contact rating (10A) and extended switching voltage capability (250VAC, 125VDC). The operating temperature range (-25°C ~ 55°C) is narrower than the original specification. This substitute is appropriate for applications requiring higher current capacity within the specified temperature range. The part is RoHS Compliant and in active production.

PT270730 is a similar substitute manufactured by TE Connectivity Potter & Brumfield Relays with the highest contact rating (12A) and maximum switching voltage (400VAC). The coil voltage is 230VAC, which falls within the acceptable operating range (184VAC minimum operate voltage). This substitute includes mechanical indicator and test button features. The part is ROHS3 Compliant and in active production. Quick Connect termination option (0.110" / 2.8mm) is available in addition to standard plug-in termination.

All substitute parts maintain the critical DPDT contact form, non-latching coil type, and socketable mounting configuration required for functional compatibility with the HC2-H-AC240V-F.

Frequently Asked Questions (FAQ)

Q: Can MY2 AC220/240 (S) replace HC2-H-AC240V-F in all applications?

A: MY2 AC220/240 (S) is functionally compatible with HC2-H-AC240V-F for applications where the load current does not exceed 5A. The original HC2-H-AC240V-F has a 7A contact rating. If your application requires the full 7A capacity, verify that the actual load current is below 5A before substitution.

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

A: The three substitutes differ primarily in contact rating and operating temperature range. MY2 AC220/240 (S) provides 5A capacity, LY2-AC220/240 provides 10A capacity with a narrower temperature range, and PT270730 provides 12A capacity with extended switching voltage (400VAC). Select based on your application's current requirements and operating environment.

Q: Are all substitute parts RoHS compliant?

A: Yes. MY2 AC220/240 (S) and LY2-AC220/240 are RoHS Compliant. PT270730 is ROHS3 Compliant. All substitutes meet current environmental compliance standards.

Q: Can PT270730 be used with the same socket as HC2-H-AC240V-F?

A: PT270730 maintains socketable mounting with standard plug-in termination compatible with HC2-H-AC240V-F sockets. PT270730 also offers Quick Connect termination (0.110" / 2.8mm) as an alternative. Verify socket compatibility with your specific application before installation.

Q: What is the coil voltage tolerance for these relays?

A: The HC2-H-AC240V-F must operate at minimum 192VAC and must release at maximum 72VAC. All substitute parts maintain these same voltage thresholds, ensuring consistent performance across the 240VAC nominal coil voltage specification.

Q: Which substitute has the widest operating temperature range?

A: HC2-H-AC240V-F operates from -50°C to 70°C. MY2 AC220/240 (S) extends the lower limit to -55°C. PT270730 operates from -40°C to 70°C. LY2-AC220/240 has the narrowest range (-25°C to 55°C). Select based on your application's environmental requirements.
