SC628AP Equivalent & Substitute Parts

Part Overview

The SC628AP 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 input range with a fixed 2.9kHz frequency output and 68dB sound pressure level at 7.5V measured at 61cm. The part is currently active in production and widely available in inventory.

Substitute parts are identified when they maintain identical electrical performance characteristics, mechanical compatibility, and mounting specifications while potentially offering improved compliance status or expanded certification coverage.

Key Parameters

Substitute Part Grouping Explanation

The SC628APR qualifies as a direct substitute for the SC628AP based on strict parameter equivalence across all critical electrical and mechanical specifications. Both parts share identical voltage range (6–28V), frequency (2.9kHz), sound pressure level (68dB @ 7.5V, 61cm), current supply (6–23mA), operating mode (Pulse, Fast), duration (2–10 PPS), mounting type (Panel Mount), termination style (Screw Terminal, Quick Connect Tab – 0.250"), and physical dimensions (1.692" Dia, 1.399" Height).

The substitution is valid because these parameters define the functional and mechanical compatibility requirements for panel mount piezo buzzer applications. No deviations exist in these core specifications between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

The SC628APR provides expanded regulatory coverage with dual cUL and UL approvals compared to the SC628AP's single cUL certification. Additionally, the SC628APR meets ROHS3 compliance requirements, whereas the SC628AP is RoHS non-compliant. Both parts maintain identical electrical performance and mechanical compatibility.

Selection between these parts depends on regulatory and compliance requirements of the target application. For applications requiring RoHS3 compliance or dual UL/cUL certification, the SC628APR is the appropriate choice. For applications with no RoHS compliance mandate and cUL certification sufficiency, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SC628APR replace SC628AP in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters including voltage range, frequency, sound pressure level, current consumption, operating mode, mounting type, termination style, and physical dimensions.

Q: What is the primary difference between SC628AP and SC628APR? A: The SC628APR includes ROHS3 compliance and dual UL/cUL certification, while the SC628AP carries only cUL certification and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel mount dimensions? A: No. Both parts share identical mounting specifications: 1.692" diameter (42.98mm) with 1.399" maximum seated height (35.54mm), and both use screw terminal with quick connect tab – 0.250" (6.35mm) termination.

Q: Do both parts operate across the same voltage and frequency range? A: Yes. Both SC628AP and SC628APR operate across 6–28V input range with fixed 2.9kHz frequency output and 68dB sound pressure level at 7.5V measured at 61cm.

Q: Which part should be selected for new designs? A: SC628APR is recommended for new designs due to expanded regulatory coverage (dual UL/cUL certification) and ROHS3 compliance, providing greater flexibility for future application requirements.
