HL1-HTM-AC240V Equivalent & Substitute Parts

Part Overview

The HL1-HTM-AC240V is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 15A switching capacity at 240VAC coil voltage. This relay is designed for chassis mount applications with quick connect termination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

The LY1F-AC220/240 manufactured by Omron Automation and Safety qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Contact Form: SPDT (1 Form C)
• Contact Rating (Current): 15 A
• Coil Voltage: 240VAC
• Mounting Type: Chassis Mount
• Coil Type: Non Latching
• Contact Material: Silver Alloy
• Must Operate Voltage: 192 VAC
• Must Release Voltage: 72 VAC

Substitution Basis: Both relays share identical contact configuration, current rating, coil voltage, and operational voltage thresholds. These parameters define the core electrical functionality required for circuit operation. The substitute maintains compatibility with the same control and load circuit requirements as the original part.

Parameter Comparison

Engineering Selection Recommendations

The LY1F-AC220/240 is an active product from Omron Automation and Safety, providing long-term availability compared to the obsolete HL1-HTM-AC240V. Both parts share identical electrical specifications for coil voltage, contact configuration, current rating, and operational voltage thresholds, establishing functional equivalence for circuit operation.

Differences in termination style (Quick Connect versus Plug In) and operating temperature range require mechanical and thermal evaluation within the specific application context. The substitute exhibits slightly longer operate and release times (25 ms versus 10 ms), which must be assessed against application timing requirements. Both parts carry identical export classification (EAR99) and moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: What makes the LY1F-AC220/240 a valid substitute for the HL1-HTM-AC240V?

A: Both relays share identical SPDT contact configuration, 15A current rating, 240VAC coil voltage, and matching operational voltage thresholds (192 VAC must operate, 72 VAC must release). These parameters define electrical compatibility with the control and load circuits.

Q: Are there mechanical compatibility considerations?

A: Yes. The original part uses Quick Connect - 0.187" (4.7mm) termination, while the substitute uses Plug In termination. Terminal connection method must be verified against the application's socket or wiring configuration.

Q: How do the timing differences affect substitution?

A: The HL1-HTM-AC240V operates and releases in 10 ms, while the LY1F-AC220/240 requires 25 ms for both functions. Applications with strict timing requirements must confirm that the longer response time is acceptable.

Q: What is the operating temperature difference impact?

A: The original part operates from -50°C to 70°C, while the substitute operates from -25°C to 55°C. Applications requiring operation below -25°C or above 55°C cannot use the substitute without thermal analysis.

Q: Does product status affect substitution validity?

A: The HL1-HTM-AC240V is obsolete, making the active LY1F-AC220/240 the practical choice for new procurement and long-term system support. Electrical equivalence remains independent of product status.
