HP2-L-AC24V Equivalent & Substitute Parts

Part Overview

The HP2-L-AC24V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10A switching capacity at 24VAC coil voltage. This socketable relay includes a lighted indicator and operates across a temperature range of -50°C to 40°C. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and replacement applications where continued operation is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HP2-L-AC24V are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for functional equivalence:

• Coil voltage: 24VAC
• Contact configuration: DPDT (2 Form C)
• Contact current rating: 10A minimum
• Mounting type: Socketable
• Coil type: Non Latching
• Termination style: Plug In, Quick Connect

The KUP-11A15-24 manufactured by TE Connectivity Potter & Brumfield Relays meets these core substitution criteria. Both relays operate on identical coil voltage, provide equivalent contact switching capacity, and utilize compatible socketable mounting with quick-connect termination.

Parameter Comparison

Engineering Selection Recommendations

The KUP-11A15-24 serves as a functional equivalent for the obsolete HP2-L-AC24V based on matching electrical specifications and socketable mounting architecture. The substitute part is currently in active production status, ensuring availability for replacement applications.

Differences in termination connector dimensions (0.205" versus 0.187") and contact material composition (Silver versus Silver Cadmium Oxide) require mechanical and electrical validation within the specific application circuit. The KUP-11A15-24 demonstrates improved switching performance with reduced operate and release times (15 ms and 10 ms respectively versus 25 ms for both parameters on the original part), and operates across a wider temperature range (-45°C to 55°C versus -50°C to 40°C).

The HP2-L-AC24V carries REACH Unaffected status, while the KUP-11A15-24 is REACH Affected. Both parts are classified under ECCN EAR99. The substitute part is RoHS non-compliant, consistent with general purpose relay manufacturing standards for this product category.

Frequently Asked Questions (FAQ)

Q: Can the KUP-11A15-24 directly replace the HP2-L-AC24V without circuit modification?

A: Both relays share identical coil voltage (24VAC), contact configuration (DPDT), and current rating (10A). However, the termination connector dimensions differ (0.205" versus 0.187"), requiring mechanical compatibility verification with the socket or terminal interface in the application circuit.

Q: What are the key electrical differences between these two relays?

A: The primary electrical differences are switching voltage specification (250VAC nominal for HP2-L-AC24V versus 240VAC maximum for KUP-11A15-24), coil current draw (78 mA versus 84 mA), and contact material composition (Silver versus Silver Cadmium Oxide). Operating and release times are faster on the substitute part (15 ms and 10 ms versus 25 ms for both).

Q: Does the wider operating temperature range of the KUP-11A15-24 affect substitution suitability?

A: The KUP-11A15-24 operates from -45°C to 55°C, compared to -50°C to 40°C for the HP2-L-AC24V. If the application requires operation below -45°C or above 55°C, the substitute part may not be suitable. For applications within the overlapping temperature range (-45°C to 40°C), both relays are functionally equivalent.

Q: What is the significance of the different contact materials?

A: The HP2-L-AC24V uses Silver (Ag) contacts, while the KUP-11A15-24 uses Silver Cadmium Oxide (AgCdO) contacts. Contact material affects arc suppression, contact wear characteristics, and switching performance. Application-specific load conditions determine whether material substitution is acceptable.

Q: Are there compliance or regulatory considerations for substitution?

A: The HP2-L-AC24V is REACH Unaffected, while the KUP-11A15-24 is REACH Affected. Both are RoHS non-compliant and classified as EAR99 for export control purposes. Regulatory requirements specific to the end application must be evaluated before substitution.
