HC1E-H-DC48V-F Equivalent & Substitute Parts

Part Overview

The HC1E-H-DC48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 48VDC coil voltage and 5A contact rating. This socketable relay is designed for general switching applications requiring sealed, fully protected operation across industrial temperature ranges.

The HC1E-H-DC48V-F is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure continued availability for maintenance and production, and support long-term product lifecycle management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC1E-H-DC48V-F must satisfy the following core electrical and mechanical criteria:

• Coil voltage: 48VDC
• Contact configuration: SPDT (1 Form C)
• Coil type: Non Latching
• Contact rating: Minimum 5A
• Switching voltage capability: Minimum 250VAC
• Operating temperature range: Must encompass or exceed -40°C ~ 60°C
• Seal rating: Sealed construction
• Relay type: General Purpose

The G2R-1-T DC48 meets these substitution criteria. While it features different mounting and termination characteristics (chassis mount with quick connect versus socketable plug-in), the electrical performance parameters and functional switching capability align with the HC1E-H-DC48V-F requirements.

Parameter Comparison

Engineering Selection Recommendations

The G2R-1-T DC48 is an active product from Omron Automation and Safety, providing long-term availability and supply chain continuity compared to the obsolete HC1E-H-DC48V-F. Both parts share identical coil voltage, contact configuration, and non-latching coil type.

The G2R-1-T DC48 offers enhanced electrical performance with 10A contact rating versus 5A, higher switching voltage capability (380VAC/125VDC versus 250VAC), and lower coil current draw (11.5mA versus 18.5mA). The extended operating temperature range (-40°C ~ 70°C) provides additional thermal margin.

Mechanical differences exist: the G2R-1-T DC48 uses chassis mount with quick connect termination, whereas the HC1E-H-DC48V-F is socketable with plug-in termination. System integration must account for these mounting and connection differences. Both parts maintain sealed construction and MSL 1 rating.

The G2R-1-T DC48 is RoHS3 compliant and REACH unaffected, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-T DC48 directly replace the HC1E-H-DC48V-F in existing applications?

A: Electrical substitution is valid based on matching coil voltage (48VDC), contact configuration (SPDT), and coil type (non-latching). However, mechanical integration requires evaluation. The G2R-1-T DC48 uses chassis mount with 0.187" quick connect terminals, while the HC1E-H-DC48V-F is socketable with plug-in termination. PCB layout, socket compatibility, and wiring harness modifications may be necessary.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are coil voltage (48VDC), contact form (SPDT/1 Form C), contact rating (minimum 5A), switching voltage capability (minimum 250VAC), and coil type (non-latching). Both parts satisfy these requirements. The G2R-1-T DC48 exceeds minimum specifications in contact rating and switching voltage.

Q: How do the coil current differences affect circuit design?

A: The HC1E-H-DC48V-F draws 18.5mA coil current; the G2R-1-T DC48 draws 11.5mA. The lower current requirement of the substitute part reduces power consumption and may improve coil driver efficiency. Existing coil drive circuits rated for 18.5mA will operate the G2R-1-T DC48 within safe margins.

Q: Are there compliance or certification differences between these parts?

A: Both parts carry MSL 1 (Unlimited) rating and EAR99 export classification. The G2R-1-T DC48 is RoHS3 compliant and REACH unaffected, supporting current regulatory standards. The HC1E-H-DC48V-F obsolete status may complicate future sourcing and compliance documentation.

Q: What is the impact of different seal ratings?

A: The HC1E-H-DC48V-F features fully sealed construction; the G2R-1-T DC48 provides sealed construction with flux protection. Both designs protect against environmental contamination. The flux protection specification of the substitute indicates suitability for soldering processes and flux residue environments.

Q: How do operating temperature ranges compare?

A: The HC1E-H-DC48V-F operates -40°C ~ 60°C; the G2R-1-T DC48 operates -40°C ~ 70°C. The substitute part provides 10°C additional upper temperature margin, supporting applications requiring extended thermal performance.
