SC628AN Equivalent & Substitute Parts

Part Overview

The SC628AN 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 range with a fixed 2.9kHz frequency and generates 80dB sound pressure level at 7.5V measured at 61cm. The part is currently active in production status. Substitute parts are identified when they maintain identical electrical performance parameters and mechanical compatibility while offering improved compliance certifications or enhanced availability.

Substitute Part Grouping Explanation

The SC628ANR qualifies as a direct substitute for the SC628AN based on strict parameter matching across all critical electrical and mechanical specifications. Both parts share identical voltage range (6–28V), frequency (2.9kHz), sound pressure level (80dB @ 7.5V, 61cm), current supply (4–30mA), mounting configuration (panel mount), termination style (screw terminal with quick connect tab), and operating temperature range (–30°C to 65°C). The substitution is valid because these parameters define the functional and physical compatibility requirements for this product category. The SC628ANR additionally carries ROHS3 compliance and dual approval certifications (cUL, UL), representing an enhanced specification variant of the same component family.

Parameter Comparison

Engineering Selection Recommendations

The SC628AN and SC628ANR are electrically and functionally equivalent components. Selection between them should be based on regulatory and compliance requirements applicable to the end application. The SC628ANR is the preferred choice for applications requiring ROHS3 compliance or dual certification (cUL and UL). The SC628AN remains suitable for applications where RoHS compliance is not mandated and cUL certification alone satisfies regulatory requirements. Both parts maintain identical electrical performance and mechanical fit within panel mount assemblies. The maximum seated height difference of 0.069" (1.77mm) between the two variants is negligible for standard panel mount applications and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can SC628ANR be used as a direct replacement for SC628AN in existing designs?

A: Yes. Both parts share identical electrical specifications (voltage range, frequency, sound pressure level, current draw) and mechanical compatibility (mounting type, termination style, panel diameter). The SC628ANR is a compatible substitute with enhanced compliance certifications.

Q: What is the difference in seated height between SC628AN and SC628ANR?

A: The SC628AN has a maximum seated height of 1.330" (33.77mm), while the SC628ANR measures 1.399" (35.54mm). This 0.069" (1.77mm) difference is within typical panel mount tolerances and does not affect standard applications.

Q: Does the SC628ANR offer any performance advantages over the SC628AN?

A: Both parts deliver identical acoustic output (80dB @ 7.5V, 61cm) and electrical performance. The SC628ANR provides enhanced regulatory compliance through ROHS3 certification and dual approval agency ratings (cUL and UL), making it suitable for applications with stricter compliance requirements.

Q: Are there any termination differences between these parts?

A: No. Both SC628AN and SC628ANR use identical termination: screw terminal with quick connect tab – 0.250" (6.35mm).

Q: Which part should be selected for new designs?

A: For new designs, the SC628ANR is recommended due to its ROHS3 compliance and dual certification status, providing better long-term regulatory alignment. The SC628AN remains valid for legacy designs or applications where RoHS compliance is not required.
