HC1-HTM-DC6V-F Equivalent & Substitute Parts

Part Overview

The HC1-HTM-DC6V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 6VDC coil. This chassis mount relay is rated for 10A switching capacity at 250VAC maximum and operates with a 150mA coil current. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and new design implementations where this relay specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-HTM-DC6V-F is determined by strict alignment of the following critical parameters:

• Coil Voltage: 6VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration (exact match required)
• Coil Type: Non Latching (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Termination Style: Plug In (exact match required)
• Coil Resistance: 40 Ohms (exact match required)
• Must Operate Voltage: 4.8 VDC (exact match required)
• Must Release Voltage: 0.6 VDC (exact match required)
• Contact Material: Silver Alloy, Cadmium Free (exact match required)

The LY1F DC6 from Omron Automation and Safety meets all critical substitution criteria. While the contact rating is higher (15A versus 10A) and switching voltage capability is extended (250VAC, 125VDC versus 250VAC only), these represent enhanced performance characteristics that do not prevent substitution in applications designed for the HC1-HTM-DC6V-F specification.

Parameter Comparison

Engineering Selection Recommendations

The LY1F DC6 is the qualified substitute for the HC1-HTM-DC6V-F. Selection is based on the following factors:

Product Status: The HC1-HTM-DC6V-F is obsolete. The LY1F DC6 is active and currently in production, ensuring availability for new procurements and ongoing system support.

Compliance: The LY1F DC6 is RoHS Compliant, meeting current environmental and regulatory standards. This compliance status is not specified for the obsolete HC1-HTM-DC6V-F.

Electrical Compatibility: Both relays share identical coil voltage (6VDC), coil current (150 mA), coil resistance (40 Ohms), must-operate voltage (4.8 VDC), and must-release voltage (0.6 VDC). Contact form, coil type, and termination style are identical.

Performance Characteristics: The LY1F DC6 provides higher contact current rating (15A versus 10A) and extended switching voltage capability (250VAC, 125VDC versus 250VAC only). Operating temperature range is narrower (-25°C ~ 55°C versus -50°C ~ 70°C), and switching times are slightly longer (25 ms versus 20 ms).

Frequently Asked Questions (FAQ)

Q: Can the LY1F DC6 directly replace the HC1-HTM-DC6V-F in existing applications?

A: Yes. Both relays share identical coil voltage, coil current, coil resistance, must-operate voltage, must-release voltage, contact form, coil type, mounting type, and termination style. The LY1F DC6 provides equal or enhanced electrical performance.

Q: What are the differences between these two relays?

A: The LY1F DC6 has a higher contact current rating (15A versus 10A), extended switching voltage capability (includes 125VDC), slightly longer switching times (25 ms versus 20 ms), a narrower operating temperature range (-25°C ~ 55°C versus -50°C ~ 70°C), and RoHS compliance status.

Q: Are there any application limitations when substituting the LY1F DC6 for the HC1-HTM-DC6V-F?

A: The narrower operating temperature range of the LY1F DC6 (-25°C ~ 55°C) may be a consideration for applications requiring the full -50°C ~ 70°C range of the original HC1-HTM-DC6V-F. Verify application temperature requirements before selection.

Q: What is the packaging difference between these relays?

A: The HC1-HTM-DC6V-F packaging is not specified in available data. The LY1F DC6 is supplied in Bulk packaging.

Q: Are both relays available for procurement?

A: The HC1-HTM-DC6V-F is obsolete and no longer in production. The LY1F DC6 is active and currently in production, with 1053 pieces available in stock.

Q: Do both relays meet the same environmental standards?

A: The LY1F DC6 is RoHS Compliant. RoHS compliance status is not specified for the obsolete HC1-HTM-DC6V-F. Both relays have Moisture Sensitivity Level 1 (Unlimited).
