Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC110DJ is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Input type (AC, DC)
• Voltage range (30–120V)
• Frequency (2kHz)
• Current supply (6–20mA)
• Sound pressure level (60dB @ 30V, 61cm)

Mechanical Compatibility:

• Mounting type (Panel Mount)
• Termination style (Screw Terminal, Quick Connect Tab – 0.250")
• Physical dimensions (1.687" Dia, 1.399" Max Height)
• Port location (Top)

Operational Compatibility:

• Operating mode (Pulse, Slow)
• Duration (0.5–2.5 PPS)
• Operating temperature range (–30°C to 65°C)

The SC110DJ is part of the SC series internally driven piezo buzzer family. Substitute parts must maintain identical electrical performance, mechanical form factor, and operational characteristics to ensure direct interchangeability without circuit redesign or mechanical rework.

Parameter Comparison

Engineering Selection Recommendations

Both SC110DJ and SC110DJR are active products from Mallory Sonalert Products Inc. with identical electrical and mechanical specifications. The SC110DJR provides enhanced regulatory compliance through UL certification in addition to cUL approval, and meets ROHS3 compliance requirements, whereas the SC110DJ is RoHS non-compliant.

Selection between these parts should be based on regulatory and environmental compliance requirements of the end application. For applications requiring RoHS3 compliance or dual cUL/UL certification, the SC110DJR is the appropriate selection. For applications with no RoHS compliance mandate and cUL certification sufficiency, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SC110DJR be used as a direct replacement for SC110DJ?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: voltage range (30–120V), frequency (2kHz), sound pressure level (60dB @ 30V, 61cm), current supply (6–20mA), mounting type (Panel Mount), termination style (Screw Terminal, Quick Connect Tab – 0.250"), and physical dimensions (1.687" Dia, 1.399" Max Height). No circuit redesign or mechanical modification is required.

Q: What is the difference between SC110DJ and SC110DJR?

A: The SC110DJR includes UL certification in addition to cUL approval and meets ROHS3 compliance. The SC110DJ carries cUL approval only and is RoHS non-compliant. Electrical performance and mechanical form factor are identical.

Q: Are there any compatibility considerations for panel mount installation?

A: Both parts share identical mounting specifications: Panel Mount configuration with top port location, 42.85mm diameter, and 35.54mm maximum seated height. Installation procedures and mechanical interfaces are identical.

Q: What operating conditions apply to both parts?

A: Both SC110DJ and SC110DJR operate across –30°C to 65°C temperature range, support AC and DC input, and function in Pulse and Slow operating modes with 0.5–2.5 PPS duration. Current supply requirement is 6–20mA across the full 30–120V voltage range.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance or dual cUL/UL certification, specify SC110DJR. For applications without these requirements, either part meets functional specifications.
