SC110J Equivalent & Substitute Parts

Part Overview

The SC110J is an internally driven piezo buzzer manufactured by Mallory Sonalert Products Inc., designed for panel mount applications with screw terminal and quick connect tab termination. This component operates across a voltage range of 30–120V AC/DC with a frequency output of 2.9kHz and sound pressure level of 68dB @ 30V, 61cm. The part is currently active in production and maintains an inventory of 752 units in stock. Substitute parts are identified when electrical specifications, mechanical dimensions, mounting configuration, and termination type remain functionally equivalent, enabling direct replacement in existing designs without circuit modification.

Substitute Part Grouping Explanation

The SC110J has one identified direct substitute: SC110JR. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Voltage range: 30–120V (AC/DC input compatibility)
• Frequency output: 2.9kHz
• Sound pressure level: 68dB @ 30V, 61cm
• Current supply: 6–22mA
• Mounting type: Panel Mount
• Termination configuration: Screw Terminal, Quick Connect Tab – 0.250" (6.35mm)
• Physical dimensions: 1.687" Dia (42.85mm), Height 1.399" (35.54mm) maximum
• Operating temperature range: –30°C to 65°C
• Driver circuitry: Indicator, Internally Driven
• Technology: Piezo

The SC110JR maintains identical electrical performance and mechanical compatibility with the SC110J, enabling direct replacement in applications where the SC110J is specified.

Parameter Comparison

Engineering Selection Recommendations

Both SC110J and SC110JR are active production parts from Mallory Sonalert Products Inc. with identical electrical and mechanical specifications. The SC110JR carries expanded regulatory approval (UL in addition to cUL) and meets ROHS3 compliance, whereas the SC110J is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. If ROHS3 compliance or UL certification is mandated, the SC110JR is the appropriate choice. If RoHS compliance is not a requirement and cUL approval is sufficient, either part is functionally equivalent. Both parts maintain current production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SC110JR be used as a direct replacement for SC110J?

A: Yes. The SC110JR is electrically and mechanically equivalent to the SC110J. Both parts operate at 30–120V, produce 2.9kHz frequency output at 68dB SPL, and share identical mounting and termination specifications. Direct substitution is possible without circuit modification.

Q: What is the difference between SC110J and SC110JR?

A: The primary differences are regulatory compliance and RoHS status. The SC110JR includes UL certification in addition to cUL and is ROHS3 compliant, while the SC110J carries only cUL approval and is RoHS non-compliant. Electrical performance and physical dimensions are identical.

Q: Are the mounting dimensions identical between SC110J and SC110JR?

A: Yes. Both parts are 1.687" diameter (42.85mm) with a maximum seated height of 1.399" (35.54mm). Panel mount configuration and screw terminal termination with 0.250" (6.35mm) quick connect tabs are identical.

Q: What termination options are available for these parts?

A: Both SC110J and SC110JR use screw terminal and quick connect tab termination with 0.250" (6.35mm) tab size. No alternative termination configurations are provided for these part numbers.

Q: What is the operating temperature range for these buzzers?

A: Both parts operate across –30°C to 65°C. This range applies to all electrical and mechanical specifications.

Q: Are these parts suitable for AC and DC applications?

A: Yes. Both SC110J and SC110JR accept AC and DC input across the 30–120V voltage range, enabling use in both AC and DC circuit designs.
