HG2-AC12V Equivalent & Substitute Parts

Part Overview

The Panasonic Electric Works HG2-AC12V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 20A at 12VAC coil voltage. This socketable relay is designed for standard switching applications requiring reliable contact performance in industrial and commercial environments. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HG2-AC12V must satisfy the following core electrical and mechanical criteria:

• Coil voltage: 12VAC
• Contact configuration: DPDT (2 Form C)
• Mounting type: Socketable
• Coil current: 300 mA
• Coil type: Non Latching
• Must operate voltage: 9.6 VAC minimum
• Termination style: Plug In compatible

The TE Connectivity Potter & Brumfield Relays part 1-1393816-8 meets these substitution criteria. However, this substitute has a reduced contact rating of 2A compared to the original 20A specification. This difference is critical and must be evaluated against the actual application requirements. The substitute is suitable only for applications where the 2A contact rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1393816-8 is an active product with current manufacturing support, making it suitable for new designs and ongoing system maintenance where the HG2-AC12V is no longer available. The substitute maintains electrical compatibility in coil voltage, contact configuration, and coil current specifications.

The primary consideration is the contact current rating differential: the substitute is rated for 2A versus the original 20A. This substitution is valid only for applications where the actual switching current does not exceed 2A. Applications requiring the full 20A contact rating cannot use this substitute.

The TE Connectivity part offers an extended operating temperature range (-40°C to 70°C) compared to the original (-50°C to 40°C), providing broader environmental compatibility. Both parts carry identical MSL and ECCN classifications, ensuring equivalent compliance status.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1393816-8 directly replace the HG2-AC12V in all applications?

A: Direct replacement is possible only in applications where the switching current does not exceed 2A. The substitute has a significantly lower contact rating (2A vs. 20A). Applications requiring higher current switching must use alternative parts with matching 20A ratings.

Q: Are the socketable mounting interfaces compatible between these relays?

A: Both relays feature socketable mounting with plug-in termination. However, physical socket compatibility depends on the specific socket design in the target equipment. Verify socket specifications before installation.

Q: What is the impact of the different switching voltage ratings?

A: The HG2-AC12V is rated for 250VAC nominal switching voltage, while the TE Connectivity substitute is rated for 125VAC maximum. The substitute is suitable for applications operating at or below 125VAC. Applications requiring 250VAC switching capability cannot use this substitute.

Q: Are there compliance differences between these parts?

A: Both parts carry identical ECCN (EAR99) and MSL (1 - Unlimited) classifications. The TE Connectivity part is active and currently manufactured, while the Panasonic part is obsolete. For new designs and long-term availability, the active TE Connectivity part is preferred.

Q: How do the operating temperature ranges affect substitution?

A: The TE Connectivity substitute operates from -40°C to 70°C, while the original operates from -50°C to 40°C. The substitute cannot be used in applications requiring operation below -40°C or above 70°C. For applications within the -40°C to 40°C range, both parts are compatible.
