Key Parameters

Substitute Part Grouping Explanation

The SC628NLR qualifies as a direct substitute for the SC628NL based on strict parameter equivalence. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics:

Key Parameters for Substitution Compatibility:

• Voltage Range: 6 ~ 28V (identical)
• Frequency: 2.9kHz (identical)
• Sound Pressure Level: 80dB @ 6V, 61cm (identical)
• Current Supply: 4 ~ 16mA (identical)
• Mounting Type: Panel Mount (identical)
• Termination: Wire Leads (identical)
• Physical Dimensions: 1.692" Dia (42.98mm), Height 1.330" (33.77mm) (identical)
• Operating Temperature Range: -30°C ~ 65°C (identical)
• Driver Circuitry: Indicator, Internally Driven (identical)
• Input Type: DC (identical)

The SC628NLR maintains full functional and mechanical compatibility with the SC628NL, allowing direct substitution in applications where the SC628NL is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the SC628NL and SC628NLR are active products from Mallory Sonalert Products Inc. with identical electrical and mechanical specifications. The SC628NLR provides additional compliance certification through cUL approval and meets ROHS3 compliance requirements, whereas the SC628NL carries UL approval only and is RoHS non-compliant. Selection between these parts should be based on specific regulatory and compliance requirements of the end application. If ROHS3 compliance is mandated, the SC628NLR is the appropriate choice. If only UL certification is required, either part is suitable. Both parts maintain identical functional performance and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SC628NLR be used as a direct replacement for SC628NL?

A: Yes. The SC628NLR is a direct substitute for the SC628NL. Both parts have identical voltage range (6 ~ 28V), frequency (2.9kHz), sound pressure level (80dB @ 6V, 61cm), current supply (4 ~ 16mA), mounting configuration (panel mount with wire leads), and physical dimensions (1.692" diameter, 1.330" height). No circuit modifications or mechanical adjustments are required.

Q: What is the difference between SC628NL and SC628NLR?

A: The primary differences are compliance certifications and RoHS status. The SC628NLR includes both cUL and UL approvals and is ROHS3 compliant, while the SC628NL carries UL approval only and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between SC628NL and SC628NLR?

A: Yes. Both parts have identical panel mount dimensions of 1.692" diameter (42.98mm) and maximum seated height of 1.330" (33.77mm). They are mechanically interchangeable in panel mount applications.

Q: What compliance certifications does each part carry?

A: The SC628NL carries UL approval. The SC628NLR carries both cUL and UL approvals and is ROHS3 compliant. Select based on your application's regulatory requirements.

Q: Do both parts operate at the same voltage and current specifications?

A: Yes. Both SC628NL and SC628NLR operate within the same voltage range of 6 ~ 28V DC and draw 4 ~ 16mA supply current. They are electrically equivalent.

Q: What is the operating temperature range for these parts?

A: Both the SC628NL and SC628NLR operate across the temperature range of -30°C to 65°C.
