HC4D-L-DC6V-D General Purpose Relay Equivalent & Substitute Parts

Part Overview

The HC4D-L-DC6V-D is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with 3A contact rating and 6VDC coil voltage. This socketable relay is designed for standard switching applications requiring multiple independent circuits. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4D-L-DC6V-D are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable operating ranges:

• Coil voltage: 6VDC (exact match required)
• Contact form: 4PDT (4 Form C) configuration (exact match required)
• Contact rating: 3 A minimum (exact match required)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In configuration (exact match required)
• Must operate voltage: 4.8 VDC or lower (ensures reliable activation)
• Must release voltage: 0.6 VDC or higher (ensures reliable deactivation)
• Switching voltage: 250VAC minimum (maintains load capacity)
• Operating temperature range: Must encompass or exceed -50°C ~ 60°C
• Coil current: Within ±2% tolerance of 150 mA
• Coil resistance: Within ±2% tolerance of 40 Ohms

The MY4N-D2 DC6 (S) from Omron Automation and Safety meets all substitution criteria and is classified as an equivalent substitute.

Engineering Selection Recommendations

The MY4N-D2 DC6 (S) is an active product from Omron Automation and Safety and serves as a direct functional equivalent to the obsolete HC4D-L-DC6V-D. Selection of the Omron substitute provides the following advantages:

• Active product status ensures continued availability and supply chain reliability
• RoHS compliance certification meets current environmental and regulatory standards
• Extended operating temperature range (-55°C ~ 70°C) provides broader environmental tolerance compared to the original specification
• Electrical parameters remain within acceptable tolerance ranges for direct circuit substitution
• Socketable mounting and plug-in termination maintain mechanical compatibility with existing socket installations

No design modifications or circuit alterations are required when substituting the MY4N-D2 DC6 (S) for the HC4D-L-DC6V-D in applications where the original relay is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-D2 DC6 (S) be used as a direct replacement for the HC4D-L-DC6V-D without circuit modification?

A: Yes. The MY4N-D2 DC6 (S) meets all electrical and mechanical specifications required for direct substitution. Coil voltage, contact configuration, current rating, switching voltage, and timing parameters are identical or within acceptable tolerance ranges. Socketable mounting and plug-in termination are compatible with existing installations.

Q: What is the significance of the coil current difference (150 mA vs. 151 mA)?

A: The 1 mA difference represents a 0.67% variance, which is within standard engineering tolerance for relay coil specifications. This difference does not affect circuit operation or relay performance in standard applications.

Q: Does the extended operating temperature range of the Omron relay affect compatibility?

A: No. The MY4N-D2 DC6 (S) operating range of -55°C ~ 70°C exceeds the original HC4D-L-DC6V-D specification of -50°C ~ 60°C. This provides enhanced environmental tolerance and maintains full compatibility for all applications within the original temperature specification.

Q: Are there any packaging or inventory considerations when sourcing the MY4N-D2 DC6 (S)?

A: The MY4N-D2 DC6 (S) is supplied in bulk packaging and is currently in active production with 913 pieces available in stock. The HC4D-L-DC6V-D is obsolete with limited remaining inventory of 1055 pieces. For new designs or long-term supply requirements, the Omron substitute is the recommended selection.

Q: What certifications apply to the MY4N-D2 DC6 (S)?

A: The MY4N-D2 DC6 (S) is RoHS compliant and carries ECCN EAR99 classification, meeting current environmental and export regulatory requirements. The original HC4D-L-DC6V-D does not list RoHS compliance status.
