HL1-H-AC115V Equivalent & Substitute Parts

Part Overview

The HL1-H-AC115V is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 115VAC coil. This socketable relay is rated for 15A switching capacity and is designed for standard industrial control applications. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HL1-H-AC115V is determined by the following critical parameters:

Contact Configuration & Rating: The substitute must maintain SPDT (1 Form C) contact form with 15A current rating to ensure functional equivalence in switching applications.

Coil Voltage Compatibility: The primary substitute, LY1-AC110/120, operates at 120VAC coil voltage. This 5V differential from the original 115VAC specification falls within acceptable industrial tolerance ranges for AC coil relays, as both voltages operate within the must-operate and must-release voltage windows of their respective designs.

Socketable Mounting: Both the main part and substitute feature socketable mounting with plug-in termination, ensuring mechanical compatibility in existing relay socket installations.

Coil Type & Switching Characteristics: Non-latching coil type is maintained. While the substitute exhibits slightly longer operate and release times (25 ms versus 10 ms), this remains within acceptable parameters for general purpose relay applications.

Environmental & Compliance Ratings: Both parts share identical MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.49.0075), confirming regulatory equivalence.

Engineering Selection Recommendations

The LY1-AC110/120 from Omron Automation and Safety is the designated substitute for the obsolete HL1-H-AC115V. Selection is supported by the following factors:

Product Status: The LY1-AC110/120 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the HL1-H-AC115V is obsolete.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0075) classifications, confirming regulatory equivalence for procurement and export purposes. The LY1-AC110/120 carries RoHS Compliant status, meeting modern environmental standards.

Functional Equivalence: Identical contact configuration (SPDT), current rating (15A), coil type (non-latching), and mounting method (socketable) ensure direct functional replacement in existing installations.

Coil Voltage Tolerance: The 5VAC differential between 115VAC and 120VAC coil specifications is within standard industrial tolerance for AC relay operation. Both designs incorporate appropriate must-operate and must-release voltage margins to accommodate this variance.

Frequently Asked Questions (FAQ)

Q: Can the LY1-AC110/120 directly replace the HL1-H-AC115V in existing installations?

A: Yes. Both relays feature identical socketable mounting, SPDT contact configuration, 15A current rating, and non-latching coil type. The 5VAC coil voltage difference (115VAC to 120VAC) is within acceptable industrial tolerance for AC relay operation.

Q: What is the significance of the coil voltage difference between 115VAC and 120VAC?

A: In AC relay applications, a 5VAC difference represents approximately 4% variance. Both the HL1-H-AC115V and LY1-AC110/120 are designed with must-operate and must-release voltage margins that accommodate standard AC supply variations. The LY1-AC110/120 must-operate voltage of 96VAC and must-release voltage of 36VAC provide adequate operational margin for 120VAC supply systems.

Q: Are there differences in switching speed between these relays?

A: Yes. The HL1-H-AC115V operates and releases in 10 ms, while the LY1-AC110/120 requires 25 ms for both operations. For applications requiring faster switching response, this difference must be evaluated against system timing requirements.

Q: What is the operating temperature range difference?

A: The HL1-H-AC115V operates from -50°C to 70°C, while the LY1-AC110/120 operates from -25°C to 55°C. For applications requiring operation below -25°C or above 55°C, the temperature range limitation of the substitute must be considered.

Q: Are both relays compatible with the same socket?

A: Both relays feature socketable mounting with plug-in termination. Mechanical compatibility is confirmed. However, socket compatibility should be verified against the specific relay socket specification in the target application.

Q: What compliance certifications apply to the LY1-AC110/120?

A: The LY1-AC110/120 is RoHS Compliant and carries ECCN EAR99 classification. It shares the same HTSUS code (8536.49.0075) as the original part, confirming regulatory equivalence for procurement purposes.
