SC628DP Equivalent & Substitute Parts

Part Overview

The SC628DP 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 6–28V DC input range, producing a 1.9kHz tone at 60dB SPL (measured at 6V, 61cm distance) with pulse/fast operating modes at 2–10 PPS. The part is currently active in production with 780 units in stock. Equivalent parts are identified when electrical performance parameters, mechanical mounting specifications, and termination methods remain consistent across the product line.

Substitute Part Grouping Explanation

Substitution eligibility for the SC628DP is determined by strict equivalence across the following critical parameters:

• Voltage Range: 6–28V DC
• Frequency: 1.9kHz
• Sound Pressure Level: 60dB @ 6V, 61cm
• Current Supply: 6–23mA
• Operating Mode: Pulse, Fast
• Duration: 2–10 PPS
• Mounting Type: Panel Mount
• Termination: Screw Terminal, Quick Connect Tab – 0.250" (6.35mm)
• Physical Dimensions: 1.692" Dia (42.98mm), Height 1.330" (33.77mm) maximum
• Operating Temperature Range: –30°C to 65°C
• Driver Circuitry: Indicator, Internally Driven
• Input Type: DC
• Technology: Piezo

The SC628DPR meets all these criteria and is classified as a direct equivalent within the SC series product line.

Parameter Comparison

Engineering Selection Recommendations

Both SC628DP and SC628DPR are functionally equivalent piezo buzzers within the SC series. The primary distinction lies in regulatory compliance:

The SC628DPR carries dual certification (cUL and UL) compared to the SC628DP (UL only) and meets ROHS3 compliance, whereas the SC628DP is RoHS non-compliant. For applications requiring RoHS3 compliance or dual North American certification, the SC628DPR is the appropriate selection. For applications without RoHS3 requirements, both parts deliver identical electrical and mechanical performance. Both parts maintain active production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SC628DPR replace SC628DP in existing designs? A: Yes. Both parts are electrically and mechanically identical across all operating parameters, voltage range, frequency, SPL output, current consumption, mounting configuration, and termination method. The SC628DPR adds RoHS3 compliance and dual certification (cUL/UL).

Q: What is the key difference between these two parts? A: The SC628DPR includes ROHS3 compliance and cUL certification in addition to UL certification. The SC628DP carries UL certification only and is RoHS non-compliant. Electrical performance and physical specifications are identical.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 1.692" diameter (42.98mm) with a maximum seated height of 1.330" (33.77mm). Panel mount and termination configurations are identical.

Q: Do both parts operate across the same voltage range? A: Yes. Both SC628DP and SC628DPR operate across 6–28V DC input with identical current consumption of 6–23mA.

Q: Which part should I select for new designs? A: Selection depends on regulatory requirements. For designs requiring RoHS3 compliance or dual North American certification, specify SC628DPR. Both parts are active in production with equivalent availability.

Q: Are the termination methods compatible? A: Yes. Both parts use screw terminal and quick connect tab termination (0.250" / 6.35mm), ensuring direct mechanical and electrical compatibility.
