SC616N-6 Equivalent & Substitute Parts

Part Overview

The SC616N-6 is an internally driven piezo buzzer manufactured by Mallory Sonalert Products Inc., designed for panel mount applications with screw terminal connectivity. This component operates across a 6–16V DC voltage range, producing a 2.9kHz single-tone output at 90dB SPL (measured at 6V, 61cm distance) with a current draw of 6–22mA. The part is classified as obsolete, necessitating identification of active equivalent models to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC616N-6 is determined by strict alignment across the following critical parameters:

• Piezo Technology & Driver Circuitry: Both the main part and substitute must employ internally driven piezo technology to ensure electrical compatibility without external driver modifications.
• Voltage Range: The substitute must operate within the 6–16V DC specification to maintain compatibility with existing power supply designs.
• Frequency Output: The 2.9kHz frequency must be preserved to ensure acoustic performance consistency in the application.
• Operating Mode: Single-tone operation is required; multi-tone or variable-frequency designs are not acceptable substitutes.
• Mechanical Compatibility: Panel mount configuration with identical or functionally equivalent termination methods, combined with matching physical dimensions (42.85mm diameter, 35.54mm maximum seated height), ensures direct mechanical fit.
• Environmental Specifications: Operating temperature range of –30°C to 65°C must be maintained.
• Regulatory Compliance: RoHS3 compliance is mandatory for continued use in regulated markets.

The SC616N-BTR meets all substitution criteria and is classified as an active product, providing long-term component availability.

Parameter Comparison

Engineering Selection Recommendations

The SC616N-BTR is the qualified substitute for the obsolete SC616N-6. Both components share identical electrical specifications (voltage range, frequency, current draw, operating temperature) and mechanical form factors (diameter, height, panel mount configuration), ensuring functional equivalence in circuit design and mechanical assembly.

The primary distinction is product status: SC616N-6 is obsolete with no ongoing manufacturing, while SC616N-BTR is an active product with confirmed inventory availability (994 units in stock). The SC616N-BTR additionally carries cUL and UL certifications, providing enhanced regulatory documentation for applications requiring third-party approval.

A secondary consideration is termination method: SC616N-6 uses screw terminals exclusively, while SC616N-BTR provides screw terminal connectivity with an integrated quick-connect tab (0.250" / 6.35mm). This enhanced termination option in the substitute part offers improved installation flexibility without compromising backward compatibility with screw terminal wiring practices.

The 10dB reduction in sound pressure level (90dB to 80dB at 6V, 61cm) must be evaluated against application acoustic requirements. If the original 90dB specification is critical to system performance, this difference should be documented in the design review.

Frequently Asked Questions (FAQ)

Q: Can SC616N-BTR be used as a direct replacement for SC616N-6 in existing designs?

A: Yes. Both parts share identical voltage range (6–16V), frequency (2.9kHz), current specifications (6–22mA), operating temperature range (–30°C to 65°C), and mechanical dimensions (42.85mm diameter, 35.54mm height). The screw terminal connection method is preserved in the substitute part, enabling direct wiring compatibility.

Q: What is the significance of the quick-connect tab feature in SC616N-BTR?

A: The SC616N-BTR includes a 0.250" (6.35mm) quick-connect tab in addition to screw terminals. This provides an optional connection method for applications using quick-disconnect connectors, while maintaining full backward compatibility with screw terminal installations. Existing designs using screw terminals require no modification.

Q: Does the 10dB difference in sound pressure level affect substitution eligibility?

A: The SPL difference (90dB vs. 80dB at 6V, 61cm) is a measurable acoustic characteristic that must be evaluated against application requirements. If the original 90dB output is functionally necessary for the intended use, this difference should be documented in the design change record. For applications where acoustic output is not a critical specification, the SC616N-BTR meets all electrical and mechanical substitution criteria.

Q: Are there any compliance or certification differences between the two parts?

A: SC616N-BTR carries cUL and UL certifications, while SC616N-6 does not specify approval agencies. Both parts are ROHS3 compliant and REACH unaffected. For applications requiring third-party certification documentation, SC616N-BTR provides enhanced regulatory support.

Q: What is the inventory status of these parts?

A: SC616N-6 is obsolete with 1,072 units currently in stock. SC616N-BTR is an active product with 994 units in stock, ensuring long-term availability for new production and field service applications.
