HC1-HP-AC120V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-AC120V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 120VAC coil. This through-hole mounted relay is rated for 10A at 250VAC maximum switching voltage and operates with a 10.9mA coil current. The product is currently obsolete, making identification of compatible substitute parts 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-AC120V-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 120VAC
• Contact Form: SPDT (1 Form C)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching
• Must Operate Voltage: 96 VAC
• Must Release Voltage: 36 VAC

Allowable Variation Parameters:

• Contact Rating (Current): Substitute must equal or exceed 10A
• Switching Voltage (Max): Substitute must equal or exceed 250VAC
• Coil Current: Substitute must not significantly exceed circuit design limits
• Operating Temperature Range: Substitute must cover or exceed the required operating environment
• Operate/Release Time: Substitute timing must be compatible with system response requirements

The LY1-0-AC110/120 from Omron Automation and Safety meets all mandatory matching criteria and exceeds performance specifications in contact current rating (15A vs. 10A) and switching voltage capability (250VAC, 125VDC vs. 250VAC).

Parameter Comparison

Engineering Selection Recommendations

The LY1-0-AC110/120 is a direct functional substitute for the obsolete HC1-HP-AC120V-F. Selection is based on the following engineering factors:

Product Status: The HC1-HP-AC120V-F is obsolete. The LY1-0-AC110/120 is active and currently in production, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0075) classifications. The LY1-0-AC110/120 carries RoHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements.

Performance Margin: The LY1-0-AC110/120 provides enhanced current rating (15A vs. 10A) and extended switching voltage capability (250VAC, 125VDC vs. 250VAC only), offering improved performance headroom for the same coil voltage and contact configuration.

Operational Compatibility: Both relays operate at identical must-operate (96VAC) and must-release (36VAC) voltages, ensuring circuit compatibility. The LY1-0-AC110/120 exhibits lower coil current (9.2mA vs. 10.9mA), reducing driver circuit loading.

Temperature Consideration: The HC1-HP-AC120V-F operates across -50°C to 70°C, while the LY1-0-AC110/120 operates across -25°C to 55°C. Applications requiring operation below -25°C or above 55°C must evaluate environmental constraints independently.

Frequently Asked Questions (FAQ)

Q: Can the LY1-0-AC110/120 directly replace the HC1-HP-AC120V-F without circuit modification?

A: Yes. Both relays share identical coil voltage (120VAC), contact form (SPDT), must-operate voltage (96VAC), and must-release voltage (36VAC). The LY1-0-AC110/120 requires no circuit redesign for standard applications. Physical footprint and pin configuration must be verified for PCB compatibility.

Q: What is the significance of the higher 15A contact rating on the LY1-0-AC110/120 compared to the 10A rating on the HC1-HP-AC120V-F?

A: The LY1-0-AC110/120 can safely switch higher currents (up to 15A) compared to the original 10A specification. This provides additional performance margin and allows the substitute to handle applications with higher current demands without exceeding contact ratings.

Q: Does the LY1-0-AC110/120 support DC switching in addition to AC?

A: Yes. The LY1-0-AC110/120 is rated for 250VAC and 125VDC maximum switching voltage, whereas the HC1-HP-AC120V-F is rated for 250VAC only. This extended capability does not affect AC-only applications.

Q: Why is the operating temperature range different between the two relays?

A: The HC1-HP-AC120V-F operates from -50°C to 70°C, while the LY1-0-AC110/120 operates from -25°C to 55°C. Applications requiring operation below -25°C or above 55°C must confirm that the LY1-0-AC110/120 meets environmental specifications. For standard industrial temperature ranges (-20°C to 60°C), both relays are suitable.

Q: What is the impact of the 5ms longer operate and release times on the LY1-0-AC110/120?

A: The LY1-0-AC110/120 has operate and release times of 25ms compared to 20ms for the HC1-HP-AC120V-F. This 5ms difference is negligible for general-purpose relay applications. Applications with strict timing requirements below 25ms must evaluate system tolerance independently.

Q: Are both relays available in the same packaging format?

A: The HC1-HP-AC120V-F is specified with through-hole mounting and PC pin termination. The LY1-0-AC110/120 is also through-hole mounted with PC pin termination, ensuring mechanical compatibility. Packaging format (Bulk for LY1-0-AC110/120) does not affect functional performance.

Q: What compliance standards apply to both relays?

A: Both relays carry ECCN EAR99 and HTSUS 8536.49.0075 classifications. The LY1-0-AC110/120 additionally carries RoHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic components.
