HL2-HTM-AC12V Equivalent & Substitute Parts

Part Overview

The HL2-HTM-AC12V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VAC coil and 10A contact rating. 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

Substitution of the HL2-HTM-AC12V is determined by strict alignment of the following critical parameters:

• Coil voltage: 12VAC (exact match required)
• Contact configuration: DPDT (2 Form C) (exact match required)
• Contact current rating: 10A minimum (equal or higher acceptable)
• Must operate and release voltages: 9.6 VAC and 3.6 VAC respectively (exact match required)
• Contact material: Silver Alloy (exact match required)
• Coil type: Non Latching (exact match required)

The LY2F-AC12 from Omron Automation and Safety meets all substitution criteria. While termination style differs (Plug In versus Quick Connect), mounting type remains Chassis Mount, and all electrical parameters align within acceptable tolerances for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The LY2F-AC12 is the qualified substitute for the obsolete HL2-HTM-AC12V. Selection is supported by:

• Active product status ensuring continued availability and supply chain reliability
• Full electrical parameter alignment including coil voltage, contact configuration, current rating, and operating/release voltage thresholds
• Identical contact material (Silver Alloy) and coil type (Non Latching)
• RoHS3 compliance providing regulatory advantage over the original part
• Equivalent REACH and ECCN classifications maintaining export and regulatory consistency

Termination style transition from Quick Connect to Plug In requires mechanical interface verification during integration. Operating temperature range narrowing (-25°C to 55°C versus -50°C to 70°C) must be evaluated against application requirements. Increased switching voltage capability (250VAC, 125VDC maximum) provides enhanced margin for high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the LY2F-AC12 directly replace the HL2-HTM-AC12V without circuit modification?

A: Electrical parameters are fully compatible. Termination style differs (Plug In versus Quick Connect), requiring mechanical interface adaptation. Verify connector compatibility with existing wiring harness before installation.

Q: What is the impact of the 15 ms increase in operate and release time?

A: The LY2F-AC12 operates and releases in 25 ms versus 10 ms for the original part. Applications with timing-critical switching requirements must evaluate whether this delay affects system performance.

Q: Is the narrower operating temperature range of the LY2F-AC12 a limitation?

A: The LY2F-AC12 operates from -25°C to 55°C compared to -50°C to 70°C for the HL2-HTM-AC12V. Applications requiring operation below -25°C or above 55°C must retain the original specification or identify alternative substitutes.

Q: What are the compliance advantages of the LY2F-AC12?

A: The LY2F-AC12 carries RoHS3 compliance, providing regulatory advantage for new designs and systems subject to environmental directives. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Q: Are there packaging differences between these relays?

A: The HL2-HTM-AC12V is packaged individually, while the LY2F-AC12 is supplied in bulk packaging. Procurement and inventory management processes may require adjustment.
