HC3-HPL-DC6V-F Equivalent & Substitute Parts

Part Overview

The HC3-HPL-DC6V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 6VDC coil. This through-hole mounted relay is designed for applications requiring switching of up to 7A at 250VAC maximum. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC3-HPL-DC6V-F are identified based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Coil Voltage: 6VDC (exact match required)
• Contact Form: 3PDT (3 Form C) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Type: Non Latching (exact match required)

Secondary Compatibility Criteria:

• Contact Rating (Current): Must be equal to or greater than 7A
• Switching Voltage: Must support 250VAC or higher
• Operating Temperature Range: Must encompass or exceed -50°C ~ 60°C
• Contact Material: Silver Alloy composition acceptable

The LY3-0-DC6 meets all primary matching criteria and exceeds secondary requirements, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The LY3-0-DC6 is a qualified substitute for the HC3-HPL-DC6V-F based on matching electrical and mechanical specifications. The substitute part provides enhanced current rating (10A versus 7A), supporting broader application flexibility. The LY3-0-DC6 is actively manufactured and RoHS compliant, providing supply chain continuity and regulatory alignment.

Design consideration: The operating temperature range of the LY3-0-DC6 (-25°C ~ 55°C) is narrower than the original part (-50°C ~ 60°C). Applications requiring operation below -25°C or above 55°C require verification of alternative substitutes or confirmation that the narrower range is acceptable for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the LY3-0-DC6 directly replace the HC3-HPL-DC6V-F in existing designs?

A: Yes, the LY3-0-DC6 matches all critical electrical and mechanical parameters: 6VDC coil, 3PDT contact form, through-hole mounting with PC pin termination, and non-latching operation. Physical footprint compatibility should be verified during board layout review.

Q: What is the significance of the higher current rating on the LY3-0-DC6?

A: The LY3-0-DC6 is rated for 10A contact current versus 7A on the HC3-HPL-DC6V-F. This higher rating provides design margin and allows the substitute to handle applications at or below the original 7A specification without derating.

Q: Are there temperature range limitations with the LY3-0-DC6?

A: The LY3-0-DC6 operates from -25°C to 55°C, compared to the HC3-HPL-DC6V-F range of -50°C to 60°C. If your application requires operation outside the -25°C to 55°C window, alternative substitutes must be evaluated.

Q: What is the packaging difference between these parts?

A: The HC3-HPL-DC6V-F is supplied in standard packaging, while the LY3-0-DC6 is supplied in bulk packaging. Bulk packaging is suitable for production environments and does not affect component functionality.

Q: Is the LY3-0-DC6 RoHS compliant?

A: Yes, the LY3-0-DC6 is RoHS compliant. The HC3-HPL-DC6V-F, being an obsolete product, does not have documented RoHS status. For applications requiring RoHS compliance, the LY3-0-DC6 is the appropriate selection.
