SC628ANP Equivalent & Substitute Parts

Part Overview

The SC628ANP 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 2.9kHz frequency output and 80dB sound pressure level at 6V measured at 61cm. The part is currently active in production and widely used in alarm, indicator, and notification applications requiring reliable audible signaling.

Finding equivalent and substitute parts becomes necessary when managing inventory constraints, addressing supply chain disruptions, or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC628ANP is determined by strict alignment across the following critical parameters:

• Electrical Compatibility: Voltage range (6–28V), frequency (2.9kHz), current supply (4–30mA), and input type (AC, DC) must match exactly
• Acoustic Performance: Sound pressure level (80dB @ 6V, 61cm) must be identical
• Mechanical Compatibility: Mounting type (panel mount), termination style (screw terminal with quick connect tab 0.250"), and diameter (42.98mm) must be identical
• Operating Environment: Temperature range (–30°C to 65°C) must be maintained
• Technology: Piezo-based, internally driven indicator technology

The SC628ANPR qualifies as a direct substitute based on these parameters. Variations in height, operating mode duration range, approval certifications, and RoHS compliance status do not disqualify substitution when electrical and mechanical specifications remain within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

SC628ANPR as Direct Substitute: The SC628ANPR maintains full electrical and mechanical compatibility with the SC628ANP across all critical parameters. The height difference of 0.069" (1.77mm) falls within typical mechanical tolerances for panel mount applications and does not affect functional performance or circuit integration.

Compliance Advantage: The SC628ANPR carries both cUL and UL certifications compared to the SC628ANP's UL-only rating, providing expanded regulatory acceptance in North American markets. Additionally, SC628ANPR achieves ROHS3 compliance, addressing environmental and regulatory requirements that may be mandated in updated design specifications or procurement policies.

Selection Basis: Choose SC628ANPR when ROHS3 compliance or dual cUL/UL certification is required. The SC628ANP remains suitable for applications where RoHS non-compliance is acceptable and UL certification alone satisfies regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SC628ANPR replace SC628ANP in existing designs without circuit modification?

A: Yes. Both parts share identical electrical specifications (voltage, frequency, current, input type) and mechanical termination (screw terminal, quick connect tab 0.250"). The height variation of 0.069" does not require circuit redesign for standard panel mount applications.

Q: What is the significance of the height difference between these parts?

A: SC628ANP has a seated height of 1.330" (33.77mm), while SC628ANPR measures 1.399" (35.54mm). This 0.069" difference is typical in component manufacturing and does not affect electrical performance or standard panel cutout dimensions. Verify clearance in space-constrained enclosures.

Q: Does RoHS3 compliance of SC628ANPR affect performance compared to the non-compliant SC628ANP?

A: No. RoHS3 compliance reflects material composition standards and does not alter electrical or acoustic performance. Both parts deliver identical 80dB sound pressure level and operate across the same 6–28V range.

Q: Are the approval certifications interchangeable between SC628ANP and SC628ANPR?

A: SC628ANPR carries cUL and UL certifications, while SC628ANP carries UL only. SC628ANPR's dual certification provides broader regulatory acceptance. For applications requiring cUL certification specifically, SC628ANPR is the appropriate selection.

Q: What operating mode differences exist between these parts?

A: SC628ANP supports pulse and fast operating modes with 2–10 PPS duration. SC628ANPR supports pulse and fast modes with 2–9 PPS duration. Both operate within overlapping ranges suitable for standard indicator and alarm applications.

Q: Can these parts be used interchangeably in AC and DC circuits?

A: Yes. Both SC628ANP and SC628ANPR accept AC and DC input types across the 6–28V range, providing circuit flexibility for either power source configuration.
