Equivalent & Substitute Parts for Panasonic AM1106F

Part Overview

The Panasonic AM1106F is a snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 10A AC at 125V and 500mA DC at 125V. This component features an overtravel plunger actuator and solder lug termination for chassis mount applications. The AM1106F is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1106F is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Mom
• Voltage rating must support 125V AC minimum
• Mounting type must be Chassis Mount
• Termination style must be Solder Lug
• Current rating must meet or exceed 10A AC at 125V

Three substitute parts meet these core criteria with varying degrees of parameter alignment:

BZ-2RS (Honeywell): Matches circuit, function, voltage, mounting, and termination. Current rating of 15A AC exceeds requirement. Overtravel plunger actuator matches AM1106F design. Active product status.

BM-1R (Honeywell): Matches circuit, function, voltage, mounting, and termination. Current rating of 22A AC exceeds requirement. Round pin plunger actuator differs from original. Active product status.

BZ-RX20 (Honeywell): Matches circuit, voltage, mounting, and termination. Switch function is On-On (differs from On-Mom). Current rating of 15A AC exceeds requirement. Obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BZ-2RS

The BZ-2RS provides the closest functional equivalence to the AM1106F. Both parts share identical circuit configuration (SPDT), switch function (On-Mom), voltage ratings (125V AC/DC), mounting type (Chassis Mount), and termination style (Solder Lug). The actuator design matches (overtravel plunger), and the current rating of 15A AC exceeds the 10A requirement. The BZ-2RS holds active product status with RoHS compliance, ensuring long-term availability and regulatory alignment.

Secondary Substitute: BM-1R

The BM-1R meets all critical electrical and mechanical parameters with a 22A AC current rating that provides additional margin above the 10A requirement. The primary distinction is the round pin plunger actuator versus the overtravel plunger design. This actuator difference may affect mechanical feel and operating characteristics in applications sensitive to actuation force or travel distance. The BM-1R is active and RoHS compliant.

Tertiary Substitute: BZ-RX20

The BZ-RX20 shares electrical ratings and mounting specifications but differs in two significant aspects: switch function is On-On rather than On-Mom, and termination is screw terminal rather than solder lug. These differences require circuit redesign and mechanical rework. Additionally, BZ-RX20 is classified as obsolete. This part is suitable only when functional differences are acceptable and long-term availability is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can BZ-2RS directly replace AM1106F without circuit modification?

A: Yes. The BZ-2RS matches all critical parameters: SPDT circuit, On-Mom function, 125V AC/DC ratings, chassis mount, and solder lug termination. No circuit redesign is required.

Q: What is the key difference between BZ-2RS and BM-1R?

A: Both are functionally equivalent for SPDT On-Mom 125V applications. The BZ-2RS uses an overtravel plunger actuator (matching AM1106F design), while BM-1R uses a round pin plunger. The BM-1R has higher current capacity (22A AC vs. 15A AC). Actuator selection depends on application-specific requirements for operating force and travel characteristics.

Q: Why is BZ-RX20 listed as a substitute if it has different switch function?

A: BZ-RX20 is included because it shares the same electrical ratings and mounting configuration. However, the On-On function (versus On-Mom) represents a functional difference requiring circuit evaluation. This part is suitable only for applications where the On-On behavior is acceptable or desired.

Q: Are all substitute parts RoHS compliant?

A: BZ-2RS and BM-1R are RoHS compliant. BZ-RX20 is RoHS compliant. The original AM1106F RoHS status is not specified in available documentation.

Q: What is the operating temperature difference between AM1106F and substitutes?

A: The AM1106F operates from -25°C to 80°C. All three substitute parts operate from -55°C to 85°C, providing extended temperature range capability. Applications operating within the AM1106F range will function identically with any substitute.

Q: Can I use BZ-RX20 with screw terminal instead of solder lug?

A: BZ-RX20 termination is screw terminal, requiring mechanical rework of the connection interface. If solder lug termination is mandatory for your assembly process, BZ-2RS or BM-1R are required.

Q: Which substitute offers the best long-term availability?

A: Both BZ-2RS and BM-1R are active products from Honeywell with RoHS compliance, ensuring continued manufacturing and supply. BZ-RX20 is obsolete and should not be selected for new designs requiring long-term component availability.
