LSC616 Equivalent & Substitute Parts

Part Overview

The LSC616 is a panel-mounted piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for internally driven indicator applications. It operates across a 6–16V DC input range, producing a 2.9kHz single-tone output at 68dB SPL (measured at 6V, 61cm distance) with a current draw of 45–67mA. The component features a 42.85mm diameter form factor with screw terminal and quick-connect tab termination.

The LSC616 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this buzzer specification.

Substitute Part Grouping Explanation

Substitution eligibility for the LSC616 is determined by strict alignment across the following critical parameters:

• Manufacturer & Series: Same manufacturer (Mallory Sonalert Products Inc.) and LSC series designation
• Technology & Driver Type: Piezoelectric technology with internally driven indicator circuitry
• Input Specification: DC input type with compatible voltage range (6–16V)
• Frequency & Operating Mode: Matching 2.9kHz frequency and single-tone operation
• Mechanical Compatibility: Identical 42.85mm panel-mount form factor with screw terminal and quick-connect tab termination (0.250" / 6.35mm)
• Environmental Range: Operating temperature range of –30°C to 65°C

The LSC616N meets all substitution criteria. While it exhibits improved acoustic output (80dB vs. 68dB SPL) and reduced current consumption (40–60mA vs. 45–67mA), these represent performance enhancements within the same functional category and do not compromise backward compatibility or system integration.

Parameter Comparison

Engineering Selection Recommendations

The LSC616N is the direct substitute for the obsolete LSC616. Both components share identical electrical specifications (voltage range, frequency, input type) and mechanical form factor (42.85mm diameter, panel-mount configuration, termination style).

The LSC616N offers two material advantages: it carries Active product status, ensuring ongoing availability and manufacturer support, and it meets ROHS3 compliance requirements, whereas the LSC616 is RoHS non-compliant. The LSC616N also provides enhanced acoustic output (80dB vs. 68dB SPL) and lower current consumption (40–60mA vs. 45–67mA), representing performance improvements without functional deviation.

The maximum seated height difference (38.28mm for LSC616N vs. 36.34mm for LSC616) is 1.94mm and must be verified against panel cutout and enclosure clearance specifications in the target application.

Frequently Asked Questions (FAQ)

Q: Can the LSC616N directly replace the LSC616 in existing designs?

A: Yes. Both components share identical voltage range (6–16V), frequency (2.9kHz), mounting type (panel mount), and termination configuration (screw terminal with 0.250" quick-connect tab). Mechanical compatibility is confirmed across all critical dimensions except maximum seated height, which differs by 1.94mm. Verify panel cutout and enclosure clearance before implementation.

Q: What is the significance of the LSC616N's higher SPL rating (80dB vs. 68dB)?

A: The LSC616N produces greater acoustic output at the same input voltage. This represents a performance enhancement and does not create compatibility issues. Applications requiring the original 68dB output specification should evaluate whether the increased SPL affects system design or user experience.

Q: Does the LSC616N's lower current consumption (40–60mA vs. 45–67mA) affect circuit design?

A: The LSC616N operates within a lower current envelope, which may reduce power supply stress and heat generation. Existing power supply designs rated for the LSC616's 45–67mA range remain compatible. No circuit redesign is required.

Q: Why is RoHS compliance status different between the two parts?

A: The LSC616 is classified as RoHS non-compliant, while the LSC616N meets ROHS3 standards. For applications subject to RoHS regulatory requirements (particularly in EU markets), the LSC616N is the compliant choice. The LSC616 remains available for legacy systems where RoHS compliance is not mandated.

Q: What does "Active" product status mean for the LSC616N?

A: Active status indicates that the LSC616N is currently manufactured and supported by Mallory Sonalert Products Inc., with ongoing availability and technical support. The LSC616's Obsolete status means it is no longer in production, making the LSC616N the recommended long-term solution for new designs and component replenishment.

Q: Are there any electrical parameter differences that would prevent substitution?

A: No. Voltage range, frequency, operating mode, input type, and operating temperature range are identical between both parts. All electrical specifications align for direct substitution.
