SC105 Piezo Buzzer Panel Mount - Equivalent & Substitute Parts

Part Overview

The SC105 is an internally driven piezo buzzer designed for panel mount applications with screw terminal and quick connect tab termination. This component operates as a single-tone indicator with a fixed frequency of 2.9kHz and sound pressure level of 60dB at 1V measured at 61cm. The part is currently active in production and widely used in electronic equipment requiring audible alert functionality. Substitute parts are identified to provide alternatives for procurement flexibility, inventory management, or when specific compliance certifications are required for end-application requirements.

Substitute Part Grouping Explanation

The SC105R is identified as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Voltage range: 1 ~ 5V (DC input)
• Frequency: 2.9kHz fixed tone
• Sound pressure level: 60dB @ 1V, 61cm
• Current consumption: 3 ~ 16mA
• Physical dimensions: 1.687" diameter, 1.330" maximum seated height
• Mounting configuration: Panel mount with screw terminal and 0.250" quick connect tab
• Operating temperature range: -30°C ~ 65°C
• Port location: Top

The SC105R maintains full compatibility with applications designed for the SC105, with the additional advantage of expanded regulatory compliance certifications (cUL and UL versus UL only) and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both SC105 and SC105R are active production parts from Mallory Sonalert Products Inc. with identical electrical performance and mechanical form factors. Selection between these parts should be based on regulatory and compliance requirements:

• SC105 is suitable for applications requiring UL certification only.
• SC105R is the preferred choice for applications requiring Canadian regulatory compliance (cUL certification) or RoHS3 compliance mandates.

Both parts are functionally interchangeable in existing designs without circuit modification or mechanical redesign. The SC105R offers expanded market applicability due to dual certification (cUL and UL) and environmental compliance status.

Frequently Asked Questions (FAQ)

Q: Can SC105R be used as a direct replacement for SC105 in existing designs?

A: Yes. The SC105R is electrically and mechanically identical to the SC105. No circuit modifications or mechanical changes are required for substitution.

Q: What is the difference between SC105 and SC105R?

A: The primary differences are regulatory certifications and RoHS compliance status. SC105R carries cUL and UL approvals (versus UL only for SC105) and is RoHS3 compliant, while SC105 is RoHS non-compliant.

Q: Are the physical dimensions identical between SC105 and SC105R?

A: Yes. Both parts have identical panel mount dimensions: 1.687" diameter with 1.330" maximum seated height. Termination configuration (screw terminal with 0.250" quick connect tab) is identical.

Q: What voltage and current specifications apply to both parts?

A: Both SC105 and SC105R operate on 1 ~ 5V DC input with current consumption of 3 ~ 16mA. Frequency output is fixed at 2.9kHz with 60dB sound pressure level at 1V measured at 61cm.

Q: Which part should be selected for new designs?

A: SC105R is recommended for new designs due to expanded regulatory compliance (cUL certification) and RoHS3 compliance status, providing broader market applicability and future regulatory alignment.

Q: Are both parts available in the same packaging?

A: Yes. Both SC105 and SC105R are supplied in bulk packaging and are currently in active production with inventory availability.
