HL2-L-AC24V Equivalent & Substitute Parts

Part Overview

The HL2-L-AC24V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10A contact rating and 24VAC coil voltage. This socketable relay includes a lighted indicator and employs silver alloy contacts for reliable switching performance. The product is currently obsolete, making equivalent and substitute parts necessary for system maintenance, repair, and new design implementations where this relay specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HL2-L-AC24V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Coil voltage: 24VAC
• Contact form: DPDT (2 Form C)
• Mounting type: Socketable
• Termination style: Plug In compatible

Secondary Compatibility Criteria:

• Contact rating current: minimum 10A
• Must operate voltage: within acceptable range for 24VAC supply
• Must release voltage: within acceptable range for circuit operation
• Operating temperature range: must encompass application requirements

Two substitute parts are identified:

Direct Substitute (LY2N-AC24): Meets all primary and secondary criteria with identical contact rating (10A), matching coil voltage, contact form, and socketable mounting. Termination style is Plug In compatible.

Similar Substitute (K10P-11A15-24): Meets all primary criteria with enhanced contact rating (15A), matching coil voltage, contact form, and socketable mounting. Termination style includes Plug In and Quick Connect options. Contact material differs (Silver Cadmium Oxide vs. Silver Alloy).

Parameter Comparison

Engineering Selection Recommendations

LY2N-AC24 (Omron): This direct substitute is the primary choice for applications requiring exact functional equivalence. The part is active in production with RoHS compliance and REACH unaffected status, supporting modern regulatory requirements. Operating temperature range (-25°C ~ 55°C) is narrower than the original; applications requiring operation below -25°C or above 55°C must be evaluated against specific environmental requirements. Operate and release times are doubled (25 ms vs. 10 ms), which may impact applications with strict timing constraints.

K10P-11A15-24 (TE Connectivity): This similar substitute provides enhanced contact rating (15A vs. 10A), accommodating higher current applications within the same form factor. The part is active in production with operating temperature range (-45°C ~ 70°C) matching the original specification. However, RoHS non-compliance and REACH affected status may restrict use in regulated industries or new equipment designs. Contact material differs (Silver Cadmium Oxide vs. Silver Alloy), affecting switching characteristics and environmental considerations. Must release voltage is significantly lower (2.4 VAC vs. 7.2 VAC), which may alter circuit behavior in applications dependent on specific release voltage thresholds.

Frequently Asked Questions (FAQ)

Q: Can LY2N-AC24 be used as a direct replacement for HL2-L-AC24V?

A: LY2N-AC24 meets all primary compatibility criteria: 24VAC coil voltage, DPDT contact form, 10A contact rating, and socketable mounting with Plug In termination. However, the operating temperature range is narrower (-25°C ~ 55°C vs. -50°C ~ 70°C), and operate/release times are doubled (25 ms vs. 10 ms). Verify that your application tolerates these differences before substitution.

Q: When should K10P-11A15-24 be selected over LY2N-AC24?

A: K10P-11A15-24 is appropriate when applications require higher current capacity (15A vs. 10A) or when operating temperature must extend to -45°C or below. The wider operating temperature range (-45°C ~ 70°C) matches the original HL2-L-AC24V specification. Regulatory compliance must be evaluated, as this part is RoHS non-compliant and REACH affected.

Q: Are the termination styles compatible between these parts?

A: HL2-L-AC24V and K10P-11A15-24 both support Plug In and Quick Connect - 0.187" (4.7mm) termination. LY2N-AC24 supports Plug In termination only. Verify socket compatibility with your application's relay base before selection.

Q: What is the impact of different contact materials on relay performance?

A: HL2-L-AC24V and LY2N-AC24 use Silver Alloy contacts, while K10P-11A15-24 uses Silver Cadmium Oxide (AgCdO). Contact material affects switching characteristics, arc resistance, and contact wear patterns. Applications with specific switching requirements or environmental exposure should maintain contact material consistency where possible.

Q: How do the differences in must operate and must release voltages affect circuit design?

A: HL2-L-AC24V and LY2N-AC24 share identical must operate (19.2 VAC) and must release (7.2 VAC) voltages, ensuring equivalent circuit behavior. K10P-11A15-24 has higher must operate voltage (20.4 VAC) and significantly lower must release voltage (2.4 VAC). Circuits designed around the original release voltage threshold may behave differently with K10P-11A15-24; circuit simulation or testing is necessary to confirm compatibility.

Q: What are the regulatory implications of selecting each substitute?

A: LY2N-AC24 is RoHS compliant and REACH unaffected, supporting modern regulatory requirements for new equipment. K10P-11A15-24 is RoHS non-compliant and REACH affected, which may restrict use in regulated industries or equipment subject to environmental directives. Verify regulatory requirements for your application and target markets before final selection.
