AM1306K Equivalent & Substitute Parts

Part Overview

The AM1306K is a snap action switch manufactured by Panasonic Electric Works, featuring Single Pole Double Throw (SPDT) circuitry with a 10A AC / 500mA DC current rating at 125V. This component is designed for chassis mount applications with screw terminal connections and an overtravel plunger actuator. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1306K is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Voltage ratings must meet or exceed 125V AC / 125V DC
• Current rating must support minimum 10A AC / 500mA DC
• Actuator type must be compatible with overtravel plunger design
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal

Based on these criteria, the following parts qualify as functional equivalents:

• BZ-2RS-A2 (Honeywell): Meets all electrical and mechanical parameters with enhanced current rating (15A AC) and extended mechanical life (20,000,000 cycles)
• BZ-2R389-A2 (Honeywell): Meets all electrical and mechanical parameters with enhanced current rating (15A AC) and extended mechanical life (20,000,000 cycles)
• BZ-3YT552 (Honeywell): Obsolete status limits practical substitution applicability

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

BZ-2RS-A2 and BZ-2R389-A2 are the recommended substitutes for AM1306K applications. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and maintain active product status. BZ-2RS-A2 features an overtravel plunger actuator with steel plunger construction, providing mechanical compatibility with the original AM1306K design. BZ-2R389-A2 uses a round pin plunger actuator, offering an alternative mechanical interface while maintaining electrical equivalence.

Both Honeywell alternatives exceed the original specifications with 15A AC current rating (versus 10A), extended operating temperature range (-55°C to 85°C versus -25°C to 80°C), and significantly extended mechanical life (20,000,000 cycles versus 5,000,000 cycles). Both parts are RoHS Compliant and carry ECCN EAR99 classification.

Secondary Consideration:

BZ-3YT552 carries obsolete product status and lacks complete technical specifications, limiting its practical value as a substitute.

Frequently Asked Questions (FAQ)

Q: Can BZ-2RS-A2 directly replace AM1306K in existing applications?

A: Yes. BZ-2RS-A2 maintains identical electrical ratings (125V AC/DC, 500mA DC minimum), circuit configuration (SPDT), switch function (On-Momentary), mounting type (Chassis Mount), and termination style (Screw Terminal). The overtravel plunger actuator design ensures mechanical compatibility. The higher current rating (15A AC) and extended temperature range provide enhanced performance margins.

Q: What is the difference between BZ-2RS-A2 and BZ-2R389-A2?

A: Both parts share identical electrical specifications and active product status. The primary difference is actuator design: BZ-2RS-A2 uses an overtravel plunger with steel construction, while BZ-2R389-A2 uses a round pin plunger. Operating position differs (1.110" versus 0.625"), and operating force ranges vary (255-368gf versus 227-368gf). Selection depends on mechanical interface requirements in the target application.

Q: Are the Honeywell substitutes RoHS compliant?

A: Yes. Both BZ-2RS-A2 and BZ-2R389-A2 are RoHS Compliant. BZ-2RS-A2 additionally carries REACH Unaffected status.

Q: What is the inventory status of substitute parts?

A: BZ-2RS-A2 has 934 pieces in stock (Bulk packaging). BZ-2R389-A2 has 793 pieces in stock (Bulk packaging). Both are available as new original components.

Q: Why is AM1306K obsolete?

A: The AM1306K is listed as obsolete by Panasonic Electric Works. Active equivalent alternatives from Honeywell provide superior specifications and ongoing product support.
