SC110HP Equivalent & Substitute Parts
Part Overview
The SC110HP 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 4.5kHz and sound pressure level of 68dB @ 30V, 61cm. The part is currently active in production with 1154 units in stock. Alternative models may be required due to RoHS compliance requirements, component availability, or specific application constraints.

Substitute Part Grouping Explanation
The SC110HPR qualifies as a direct substitute for the SC110HP based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters:
- Voltage range: 30–120V (identical)
- Frequency: 4.5kHz (identical)
- Current supply: 6–20mA (identical)
- Sound pressure level: 68dB @ 30V, 61cm (identical)
- Operating mode: Pulse, Fast (identical)
- Duration: 2–10 PPS (identical)
- Mounting type: Panel Mount (identical)
- Termination: Screw Terminal, Quick Connect Tab – 0.250" (6.35mm) (identical)
- Physical dimensions: 1.687" Dia (42.85mm), Height 1.399" (35.54mm) (identical)
- Operating temperature: –30°C to 65°C (identical)
The SC110HPR maintains full functional and mechanical compatibility with the SC110HP across all specified parameters.

Engineering Selection Recommendations
The SC110HPR is a direct functional and mechanical equivalent to the SC110HP. The primary distinction is regulatory compliance: the SC110HPR achieves ROHS3 compliance, whereas the SC110HP is RoHS non-compliant. Both parts maintain active production status and are REACH Unaffected.
Selection between these parts should be based on regulatory requirements applicable to the end application. Applications subject to RoHS directives or customer specifications requiring RoHS3 compliance must use the SC110HPR. Applications without such constraints may use either part based on availability and procurement considerations.
Frequently Asked Questions (FAQ)
Q: Can SC110HPR replace SC110HP in existing designs? A: Yes. The SC110HPR is mechanically and electrically identical to the SC110HP across all specified parameters, including voltage range, frequency, current supply, sound pressure level, mounting configuration, and physical dimensions. Direct substitution is possible without circuit or mechanical modifications.
Q: What is the primary difference between SC110HP and SC110HPR? A: The SC110HPR is ROHS3 compliant, while the SC110HP is RoHS non-compliant. All other electrical and mechanical specifications are identical.
Q: Are there any compatibility concerns with panel mount installation? A: No. Both parts use identical panel mount configurations with screw terminal and quick connect tab termination (0.250" / 6.35mm). Physical dimensions are identical: 1.687" diameter with maximum seated height of 1.399".
Q: Do both parts operate across the same voltage and frequency ranges? A: Yes. Both SC110HP and SC110HPR operate at 30–120V AC/DC input with 4.5kHz frequency output, 6–20mA current supply, and 68dB sound pressure level @ 30V, 61cm.
Q: Which part should be selected for new designs? A: For new designs, the SC110HPR is recommended due to ROHS3 compliance, ensuring alignment with current regulatory standards and future supply chain requirements.
