HC1-HP-DC6V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-DC6V-F is a general purpose relay manufactured by Panasonic Electric Works, configured as a Single Pole Double Throw (SPDT) contact form with a 6VDC coil. This through-hole mounted relay is rated for 10A switching capacity at 250VAC maximum and features a 40-ohm coil resistance with 150mA coil current draw. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where the original component is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-HP-DC6V-F is determined by alignment of the following critical electrical parameters: coil voltage (6VDC), coil current (150mA), coil resistance (40 ohms), must-operate voltage (4.8VDC), must-release voltage (0.6VDC), contact current rating (10A), and maximum switching voltage (250VAC). The contact form represents a functional difference: the HC1-HP-DC6V-F provides SPDT (1 Form C) switching, while the identified substitute LY2-DC6 provides DPDT (2 Form C) switching. This difference means the LY2-DC6 offers additional switching capability beyond the original specification. Mechanical compatibility is affected by mounting type (through-hole versus socketable) and termination style (PC pin versus plug-in), which require circuit board redesign or adapter solutions for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The LY2-DC6 from Omron Automation and Safety is an active product with RoHS compliance certification, providing supply chain continuity for applications requiring the HC1-HP-DC6V-F. Electrical compatibility is established through matching coil voltage, coil current, coil resistance, and voltage thresholds. The LY2-DC6 provides expanded switching capability with DPDT contact form versus the original SPDT configuration, allowing use in applications requiring additional switching poles without exceeding the 10A contact rating or 250VAC switching voltage limits.

Mechanical integration requires consideration of the mounting and termination differences. The LY2-DC6 socketable design with plug-in termination differs from the through-hole PC pin configuration of the HC1-HP-DC6V-F, necessitating either circuit board modification or use of an appropriate socket adapter. The operating temperature range of the LY2-DC6 (-25°C ~ 55°C) is narrower than the original part (-50°C ~ 70°C), which may be a limiting factor in extreme temperature applications. Switching speed differs slightly, with the LY2-DC6 operating and releasing 5ms slower than the original specification.

Frequently Asked Questions (FAQ)

Q: Can the LY2-DC6 directly replace the HC1-HP-DC6V-F without circuit board modification?

A: Direct replacement without modification is not possible due to mounting type and termination style differences. The HC1-HP-DC6V-F uses through-hole PC pins, while the LY2-DC6 uses socketable plug-in termination. Circuit board redesign or an appropriate socket adapter is required.

Q: What is the significance of the contact form difference between SPDT and DPDT?

A: SPDT (Single Pole Double Throw) provides one switching pole with two positions. DPDT (Double Pole Double Throw) provides two independent switching poles. The LY2-DC6 offers additional switching capability, making it suitable for applications requiring more complex switching logic while maintaining compatibility with the original 10A current rating and 250VAC switching voltage.

Q: Are the coil electrical characteristics identical between these two relays?

A: Yes. Both relays share identical coil voltage (6VDC), coil current (150mA), coil resistance (40 ohms), must-operate voltage (4.8VDC), and must-release voltage (0.6VDC). This electrical equivalence ensures compatible drive circuit requirements.

Q: Does the operating temperature range difference affect substitution suitability?

A: The LY2-DC6 operating range (-25°C ~ 55°C) is narrower than the HC1-HP-DC6V-F (-50°C ~ 70°C). Applications requiring operation below -25°C or above 55°C cannot use the LY2-DC6 as a substitute.

Q: What is the impact of the 5ms difference in switching speed?

A: The LY2-DC6 operates and releases 5ms slower than the original (25ms versus 20ms). Applications with timing-critical switching requirements must evaluate whether this difference affects system performance.

Q: Is the LY2-DC6 RoHS compliant?

A: Yes, the LY2-DC6 is RoHS compliant. The HC1-HP-DC6V-F RoHS status is not specified in the available data.
