SC616JUR Equivalent & Substitute Parts

Part Overview

The SC616JUR is an internally driven piezo buzzer manufactured by Mallory Sonalert Products Inc., designed for panel mount applications with screw terminal and quick connect tab connections. This component operates across a 6–16V DC range, producing a 2.9kHz tone at 68dB SPL (measured at 6V, 61cm distance) with a 12mA supply current. The SC616JUR is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The SC616JU-1R qualifies as a direct substitute for the SC616JUR based on the following alignment of critical parameters:

• Frequency: Both parts operate at 2.9kHz
• Sound Pressure Level: Both produce 68dB SPL @ 6V, 61cm
• Voltage Range: Both operate across 6–16V DC
• Mounting Configuration: Both feature panel mount with identical screw terminal and quick connect tab termination (0.250" / 6.35mm)
• Physical Dimensions: Both share identical diameter (1.687" / 42.85mm) and seated height (1.809" / 45.96mm)
• Operating Temperature Range: Both rated –30°C to 65°C
• Compliance: Both are ROHS3 compliant

The SC616JU-1R differs in current supply specification (2–12mA range versus fixed 12mA) and operating mode duration (0.5–2.5 PPS), offering greater operational flexibility. The SC616JU-1R maintains active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The SC616JU-1R is the direct active equivalent for the obsolete SC616JUR. Both components meet identical electrical and mechanical specifications for frequency, voltage range, sound pressure level, mounting configuration, and physical dimensions. The SC616JU-1R maintains ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to the original part.

The SC616JU-1R's variable current supply range (2–12mA) encompasses the SC616JUR's fixed 12mA specification, ensuring functional compatibility across all operating conditions. The addition of duration specification (0.5–2.5 PPS) in the SC616JU-1R provides operational flexibility without compromising backward compatibility.

Selection of the SC616JU-1R is supported by active product status, ensuring long-term availability, technical support, and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SC616JU-1R directly replace the SC616JUR in existing designs?

A: Yes. Both parts share identical frequency (2.9kHz), voltage range (6–16V), sound pressure level (68dB @ 6V, 61cm), mounting type (panel mount), termination style (screw terminal with 0.250" quick connect tab), and physical dimensions (1.687" diameter, 1.809" seated height). Electrical and mechanical compatibility is complete.

Q: What is the significance of the current supply difference between the two parts?

A: The SC616JUR specifies a fixed 12mA supply current, while the SC616JU-1R operates across a 2–12mA range. The SC616JU-1R's variable range encompasses the original part's specification, ensuring functional compatibility. Existing circuit designs operating at 12mA will function identically with the SC616JU-1R.

Q: Does the SC616JU-1R's duration specification (0.5–2.5 PPS) affect compatibility?

A: No. The duration specification describes the pulse repetition rate capability of the SC616JU-1R, which does not alter its core acoustic or electrical performance. Both parts maintain pin selectable operating mode, preserving design flexibility.

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

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent, supporting use in applications with identical environmental and safety requirements.

Q: Why is the SC616JUR classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number. The SC616JU-1R represents the active continuation of this product line, offering equivalent performance with enhanced operational flexibility and assured long-term availability.
