SC616NJ Equivalent & Substitute Parts

Part Overview

The SC616NJ is an internally driven piezo buzzer manufactured by Mallory Sonalert Products Inc., designed for panel-mounted applications requiring audible indication. This component operates across a 6–16V DC input range, producing a 2.9kHz tone at 80dB sound pressure level (SPL) measured at 6V and 61cm distance. The device features screw terminal and quick connect tab termination with a 42.85mm diameter form factor. As an active product with established inventory availability, the SC616NJ serves applications requiring reliable piezo-based audible signaling in industrial and commercial control systems. Equivalent parts are identified to support procurement flexibility, design continuity, and supply chain optimization.

Substitute Part Grouping Explanation

The SC616NJR qualifies as a direct equivalent to the SC616NJ based on the following critical substitution parameters:

Electrical Compatibility:

• Identical voltage range (6–16V DC)
• Identical frequency output (2.9kHz)
• Identical current supply specification (6–22mA)
• Identical sound pressure level (80dB @ 6V, 61cm)
• Identical input type (DC) and driver circuitry (Indicator, Internally Driven)

Mechanical Compatibility:

• Identical mounting type (Panel Mount)
• Identical termination style (Screw Terminal, Quick Connect Tab – 0.250")
• Identical diameter (1.687" / 42.85mm)
• Compatible operating temperature range (–30°C to 65°C)

Functional Compatibility:

• Identical technology (Piezo)
• Identical operating modes (Pulse, Slow)
• Overlapping pulse duration range (SC616NJ: 0.5–2 PPS; SC616NJR: 0.5–4.6 PPS)

The SC616NJR maintains full electrical and mechanical interchangeability with the SC616NJ, enabling direct substitution in existing designs and applications.

Engineering Selection Recommendations

SC616NJ Selection:

• Use when existing designs are locked to the original part number and form factor
• Suitable for applications where RoHS compliance is not a requirement
• Appropriate when UL certification alone satisfies regulatory requirements

SC616NJR Selection:

• Preferred for new designs requiring ROHS3 compliance
• Recommended when dual certification (cUL and UL) is required or beneficial
• Advantageous in applications with space constraints due to reduced seated height (35.54mm vs. 45.96mm)
• Supports extended pulse duration range (0.5–4.6 PPS vs. 0.5–2 PPS), providing greater operational flexibility

Both parts maintain identical electrical performance, frequency output, and sound pressure level specifications. The SC616NJR represents an enhanced variant with improved regulatory compliance and mechanical optimization.

Frequently Asked Questions (FAQ)

Q: Can SC616NJR be used as a direct replacement for SC616NJ? A: Yes. The SC616NJR is electrically and mechanically equivalent to the SC616NJ. Both operate at identical voltage ranges (6–16V), frequency (2.9kHz), current draw (6–22mA), and sound pressure level (80dB @ 6V, 61cm). Termination and mounting specifications are identical.

Q: What is the difference in physical dimensions between these parts? A: Both parts share the same diameter (1.687" / 42.85mm). The seated height differs: SC616NJ is 1.809" (45.96mm), while SC616NJR is 1.399" (35.54mm). The SC616NJR is approximately 10.4mm shorter, which may be advantageous in space-constrained panel designs.

Q: Are there compliance differences between SC616NJ and SC616NJR? A: Yes. The SC616NJ carries UL certification and is RoHS non-compliant. The SC616NJR carries both cUL and UL certifications and is ROHS3 compliant. For applications requiring environmental or regulatory compliance, SC616NJR is the preferred choice.

Q: Do both parts support the same operating modes? A: Both parts support Pulse and Slow operating modes. The pulse duration range differs slightly: SC616NJ operates at 0.5–2 PPS, while SC616NJR operates at 0.5–4.6 PPS. The SC616NJR provides a wider operational range.

Q: What termination options are available? A: Both parts use identical termination: Screw Terminal with Quick Connect Tab – 0.250" (6.35mm). No termination conversion is required when substituting between these parts.

Q: Are both parts currently in production? A: Yes. Both SC616NJ and SC616NJR are active products with current inventory availability from Mallory Sonalert Products Inc.
