MSR516NJ Equivalent & Substitute Parts

Part Overview

The MSR516NJ is a 23mm through-hole piezo buzzer manufactured by Mallory Sonalert Products Inc., designed for internally driven indicator applications. This component operates across a 5–16V DC range with a 3.9kHz frequency output and delivers 75dB sound pressure level at 5V measured at 61cm. The MSR516NJ is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The MSR516NJR qualifies as a direct substitute for the MSR516NJ based on the following alignment of critical electrical and mechanical parameters:

Electrical compatibility is established through matching voltage range (5–16V), frequency (3.9kHz), current supply specification (3–12mA), input type (DC), driver circuitry (Indicator, Internally Driven), and operating mode (Pulse, Slow). Mechanical compatibility is confirmed by identical mounting type (Through Hole), termination style (PC Pins), physical dimensions (0.906" diameter / 23.00mm), and seated height (0.421" / 10.70mm).

The MSR516NJR differs from the MSR516NJ in product status (Active vs. Obsolete), sound pressure level measurement conditions (86dB @ 5V, 30cm vs. 75dB @ 5V, 61cm), operating temperature range (–40°C to 85°C vs. –20°C to 65°C), RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant), and packaging format (Bulk vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The MSR516NJR is the direct substitute for the obsolete MSR516NJ. Selection of the MSR516NJR is supported by its Active product status, ensuring long-term availability and manufacturing continuity. The MSR516NJR provides ROHS3 compliance, addressing regulatory requirements that the original MSR516NJ does not meet. The extended operating temperature range (–40°C to 85°C) of the MSR516NJR accommodates broader environmental conditions compared to the MSR516NJ (–20°C to 65°C). All critical electrical parameters—voltage range, frequency, current supply, and operating mode—remain identical, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the MSR516NJR directly replace the MSR516NJ in existing designs?

A: Yes. The MSR516NJR maintains identical electrical specifications (5–16V, 3.9kHz, 3–12mA) and mechanical dimensions (23mm diameter, 10.70mm height, Through Hole PC Pins), enabling direct substitution without circuit modification.

Q: What is the difference in sound pressure level between these parts?

A: The MSR516NJ produces 75dB at 5V measured at 61cm, while the MSR516NJR produces 86dB at 5V measured at 30cm. These measurements are taken at different distances, making direct acoustic comparison dependent on application-specific measurement conditions.

Q: Does the MSR516NJR offer improved environmental performance?

A: The MSR516NJR operates across –40°C to 85°C, compared to the MSR516NJ range of –20°C to 65°C. This extended temperature range provides greater operational flexibility in temperature-sensitive applications.

Q: What is the significance of RoHS compliance for the MSR516NJR?

A: The MSR516NJR is ROHS3 compliant, whereas the MSR516NJ is RoHS non-compliant. ROHS3 compliance ensures the component meets current regulatory standards for restricted hazardous substances, supporting compliance requirements in regulated industries and markets.

Q: Are the packaging formats interchangeable?

A: The MSR516NJ is supplied in standard packaging, while the MSR516NJR is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement volume and inventory management requirements.
