HP2-AC6V Equivalent & Substitute Parts Reference

Part Overview

The HP2-AC6V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10A contact rating and 6VAC coil voltage. This socketable relay is designed for standard switching applications requiring dual-pole, dual-throw functionality. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support where direct replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HP2-AC6V is determined by strict equivalence in the following critical parameters:

• Coil voltage: 6VAC (exact match required)
• Contact configuration: DPDT (2 Form C) (exact match required)
• Contact current rating: 10A minimum (equal or higher acceptable)
• Mounting type: Socketable (exact match required)
• Coil type: Non Latching (exact match required)
• Termination style: Plug In, Quick Connect (mechanical compatibility required)

The KUP-11A15-6 meets these substitution criteria. Both relays operate on 6VAC coils, feature identical DPDT contact configurations, support 10A switching capacity, utilize socketable mounting, and employ non-latching coil designs with compatible quick-connect termination systems.

Parameter Comparison

Engineering Selection Recommendations

The KUP-11A15-6 is an active product from TE Connectivity Potter & Brumfield Relays and serves as a direct functional equivalent to the obsolete HP2-AC6V. Both relays share identical electrical specifications for coil voltage, contact configuration, and current rating, ensuring compatibility in legacy system applications.

The KUP-11A15-6 offers improved operational characteristics, including faster operate and release times (15 ms and 10 ms respectively versus 25 ms for both parameters on the HP2-AC6V). The substitute part supports an extended operating temperature range (-45°C to 55°C versus -50°C to 40°C), providing broader environmental tolerance.

Minor mechanical differences exist in termination pin spacing (0.187" on KUP-11A15-6 versus 0.205" on HP2-AC6V). Socket compatibility must be verified during integration. Contact material differs (Silver Cadmium Oxide versus pure Silver), which may affect performance in specific switching applications; however, both materials are suitable for general-purpose relay applications at the specified voltage and current ratings.

Both parts carry EAR99 export classification. The KUP-11A15-6 is RoHS3 compliant and currently in active production, ensuring long-term availability for replacement and new designs.

Frequently Asked Questions (FAQ)

Q: Can the KUP-11A15-6 directly replace the HP2-AC6V in existing sockets?

A: Electrical compatibility is confirmed. However, the termination pin spacing differs (0.187" versus 0.205"). Socket mechanical compatibility must be verified before installation. If the socket accommodates both pin spacings, direct substitution is feasible.

Q: What are the key differences in operating characteristics?

A: The KUP-11A15-6 operates faster, with 15 ms operate time and 10 ms release time compared to 25 ms for both on the HP2-AC6V. The substitute part also supports a wider temperature range (-45°C to 55°C versus -50°C to 40°C). These differences are advantageous for most applications.

Q: Are there contact material compatibility concerns?

A: The HP2-AC6V uses pure Silver (Ag) contacts, while the KUP-11A15-6 uses Silver Cadmium Oxide (AgCdO). Both materials are suitable for general-purpose switching at 10A and 240-250VAC. Material selection depends on specific load characteristics and application requirements; consult application-specific data if switching inductive or capacitive loads.

Q: What is the coil current difference, and does it matter?

A: The KUP-11A15-6 draws 335 mA compared to 310 mA for the HP2-AC6V. This 25 mA difference is within typical design margins and should not affect circuit performance in standard applications. Verify that the coil drive circuit can supply the higher current if operating near design limits.

Q: Is the KUP-11A15-6 available for new designs?

A: Yes. The KUP-11A15-6 is an active product in production. The HP2-AC6V is obsolete. For new designs and ongoing production, the KUP-11A15-6 is the recommended choice.
