AM50045C53-A Equivalent & Substitute Parts

Part Overview

The AM50045C53-A is a snap-action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component operates at 125V AC / 30V DC with a 100mA current rating and features lever/roller actuation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM50045C53-A is determined by the following critical parameters that must align with the original component's electrical and mechanical specifications:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Mounting type (Chassis Mount)
• Actuator type (Lever/Roller)
• Termination style compatibility (Quick Connect)
• Operating temperature range capability
• Voltage and current rating compatibility

The identified substitute parts maintain the same SPDT circuit topology and on-momentary function. However, substitutes may vary in current rating capacity, voltage specifications, and operational life cycles. The termination style and mounting configuration remain consistent across all alternatives, ensuring mechanical compatibility in chassis mount applications.

Parameter Comparison

Engineering Selection Recommendations

LS0851505F160C2A (E-Switch) is suitable for applications requiring higher current capacity (15A AC at 125V). This substitute maintains voltage compatibility with the original part and is actively manufactured with ROHS3 compliance. The termination connector size differs (0.250" vs. 0.187"), requiring connector adaptation. Operating temperature range is reduced to 85°C maximum.

LS085R105F160C1A (E-Switch) is appropriate for low-voltage applications (20V AC/DC at 0.4VA). This substitute maintains the original termination style (0.187" quick connect) and is actively produced with ROHS3 compliance. This option is limited to lower voltage and current applications compared to the original specification.

Both E-Switch alternatives are active products with current manufacturing support and regulatory compliance documentation, providing long-term availability advantages over the obsolete Panasonic component.

Frequently Asked Questions (FAQ)

Q: Can LS0851505F160C2A directly replace AM50045C53-A in all applications?

A: Electrical compatibility exists at 125V AC operation. However, the termination connector differs (0.250" vs. 0.187"), requiring mechanical adapter consideration. The higher current rating (15A vs. 100mA) is suitable for the original application but does not guarantee drop-in compatibility without connector modification.

Q: What are the voltage limitations when using LS085R105F160C1A as a substitute?

A: LS085R105F160C1A operates at maximum 20V AC/DC, significantly lower than the original AM50045C53-A specification of 125V AC / 30V DC. This substitute is only applicable to low-voltage circuit designs and cannot be used in applications requiring the original voltage ratings.

Q: How do the operational life cycles compare between the original and substitute parts?

A: The AM50045C53-A provides 100,000 electrical cycles and 10,000,000 mechanical cycles. Both E-Switch substitutes offer 50,000 electrical cycles and 1,000,000 mechanical cycles, representing reduced operational life. Application duty cycle requirements must be evaluated against these specifications.

Q: Are the substitute parts RoHS compliant?

A: Both E-Switch alternatives (LS0851505F160C2A and LS085R105F160C1A) are ROHS3 compliant. The original Panasonic part RoHS status is not specified in available documentation.

Q: What is the impact of the reduced operating temperature range in the substitutes?

A: The original AM50045C53-A operates from -25°C to 105°C. Both E-Switch substitutes operate from -25°C to 85°C, a 20°C reduction in maximum temperature capability. Applications requiring operation above 85°C cannot use these substitutes.

Q: Do the substitutes maintain the same actuator characteristics?

A: All parts feature lever/roller actuators with identical operating position (0.815" / 20.7mm) and release force (40gf). The original part requires 220gf operating force, while substitutes require 160gf, resulting in lighter actuation force.
