HC2-H-DC100V-F Equivalent & Substitute Parts

Part Overview

The HC2-H-DC100V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 100VDC coil. This socketable relay is rated for 7A at 250VAC maximum switching voltage and operates with a 20ms response time in both energize and de-energize cycles. The product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible relay functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC2-H-DC100V-F is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact form must be DPDT (2 Form C)
• Mounting type must be socketable with plug-in termination
• Coil voltage must be within the operating range of 100VDC ±10% (80VDC minimum operate voltage to 110VDC nominal)
• Contact rating must support minimum 7A switching capacity
• Maximum switching voltage must be 250VAC or higher
• Operate and release times must be 20ms or faster
• Operating temperature range must encompass -50°C to 70°C or be compatible with the application environment

Identified Substitutes:

Direct Substitute: MY2 DC100/110 (S) by Omron Automation and Safety meets all primary criteria with 110VDC coil voltage, DPDT configuration, socketable mounting, and 5A contact rating. Although the contact rating is lower at 5A versus 7A, the 110VDC coil voltage and identical contact form provide functional equivalence for applications not requiring the full 7A capacity.

Similar Substitute: 7760056053 by Weidmüller provides enhanced current capacity at 10A with 110VDC coil voltage and DPDT configuration. This part exceeds the original specifications in contact rating and includes a lighted indicator feature. The operating temperature range is narrower (-40°C to 60°C) compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

MY2 DC100/110 (S) Selection Criteria: This Omron substitute is appropriate for applications where the 5A contact rating is sufficient for the load requirements. The 110VDC coil voltage is compatible with the original 100VDC specification within standard industrial tolerance. The part is currently in active production status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The operating temperature range of -55°C to 70°C exceeds the original specification, providing enhanced environmental compatibility.

7760056053 Selection Criteria: This Weidmüller substitute is suitable for applications requiring contact ratings exceeding 7A, with a maximum of 10A capacity. The 110VDC coil voltage and identical DPDT configuration ensure functional compatibility. Active product status and RoHS compliance support procurement and regulatory requirements. The narrower operating temperature range of -40°C to 60°C requires verification against application environmental specifications. The integrated lighted indicator feature provides additional functionality not present in the original part.

Compliance Considerations: Both substitute parts carry RoHS compliance certification, whereas the original HC2-H-DC100V-F does not specify compliance status. Both substitutes are classified under ECCN EAR99 and HTSUS 8536.49.0050 (Weidmüller uses 8536.49.0075), consistent with general purpose relay classification.

Frequently Asked Questions (FAQ)

Q: Can the MY2 DC100/110 (S) directly replace the HC2-H-DC100V-F in all applications?

A: The MY2 DC100/110 (S) provides functional equivalence in contact form, mounting type, and response time. The primary consideration is the reduced contact rating of 5A versus the original 7A. Applications operating at or below 5A load current can use this substitute without modification. Applications requiring the full 7A capacity should evaluate the Weidmüller 7760056053 alternative.

Q: What is the impact of the 110VDC coil voltage versus the original 100VDC specification?

A: The 110VDC coil voltage in both substitutes is within acceptable industrial tolerance for 100VDC-rated systems. The original part specifies a must-operate voltage of 80VDC and must-release voltage of 10VDC. The Omron substitute operates at 88VDC minimum and releases at 11VDC, while the Weidmüller substitute operates at 82.5VDC minimum and releases at 11VDC. Both substitutes function reliably within standard 100VDC supply systems.

Q: Are there any temperature range limitations when substituting these relays?

A: The original HC2-H-DC100V-F operates from -50°C to 70°C. The Omron MY2 DC100/110 (S) extends the lower limit to -55°C, providing enhanced cold-temperature performance. The Weidmüller 7760056053 operates from -40°C to 60°C, which is narrower than the original specification. Applications requiring operation below -40°C or above 60°C should use the Omron substitute or verify the Weidmüller part against specific environmental requirements.

Q: What are the packaging and inventory considerations for these substitutes?

A: The Omron MY2 DC100/110 (S) is available in bulk packaging with 1096 pieces in stock. The Weidmüller 7760056053 is also available in bulk packaging with 1071 pieces in stock. Both parts are currently in active production, ensuring ongoing availability for procurement.

Q: Does the lighted indicator feature on the Weidmüller relay affect compatibility?

A: The lighted indicator on the 7760056053 is an additional feature that does not affect electrical compatibility or socket compatibility. The indicator provides visual confirmation of relay energization, which may be beneficial in some applications but is not required for functional substitution.

Q: How do the coil current specifications compare between the original and substitute parts?

A: The original HC2-H-DC100V-F draws 11mA coil current. The Omron substitute draws 9mA, reducing power consumption by approximately 18%. The Weidmüller substitute draws 10mA, reducing consumption by approximately 9%. Both substitutes operate with lower coil current, which may reduce heat generation and improve overall system efficiency.
