Substitute Part Grouping Explanation

Substitution for the SC628L is determined by strict equivalence across the following critical parameters:

• Voltage Range: 6 ~ 28V DC
• Frequency: 2.9kHz
• Technology: Piezo with internal driver circuitry
• Operating Mode: Single Tone
• Sound Pressure Level: 68dB @ 6V, 61cm
• Current Supply: 4 ~ 18mA
• Mounting Type: Panel Mount with wire lead termination
• Physical Dimensions: 1.692" diameter, 1.330" maximum seated height
• Operating Temperature Range: -30°C ~ 65°C
• Approval Agency: UL certification

The SC628LR is classified as a direct substitute based on identical electrical performance, mechanical compatibility, and functional specifications. The primary distinction between these parts is compliance status.

Parameter Comparison

Engineering Selection Recommendations

The SC628LR serves as a direct electrical and mechanical substitute for the SC628L. Both parts maintain identical functional specifications, electrical performance characteristics, and physical dimensions required for panel mount applications.

The SC628LR offers ROHS3 compliance, whereas the SC628L is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives or customer specifications requiring RoHS-compliant components. Both parts retain UL approval and REACH unaffected status.

Selection between SC628L and SC628LR should be based on compliance requirements of the target application and design phase. For new designs or applications with RoHS compliance mandates, SC628LR is the appropriate selection. For legacy systems or applications without RoHS requirements, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SC628LR be used as a direct replacement for SC628L in existing designs?

A: Yes. The SC628LR is electrically and mechanically identical to the SC628L. All electrical parameters, operating ranges, physical dimensions, and functional characteristics are equivalent. The primary difference is RoHS compliance status.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance indicates adherence to the Restriction of Hazardous Substances directive. The SC628LR meets these environmental and material restrictions, while the SC628L does not. Selection depends on whether the application or customer specifications require RoHS compliance.

Q: Are the physical dimensions identical between SC628L and SC628LR?

A: Yes. Both parts share identical panel mount dimensions of 1.692" diameter and 1.330" maximum seated height, with wire lead termination. No mechanical redesign or panel modifications are required for substitution.

Q: Do both parts operate within the same voltage and current ranges?

A: Yes. Both SC628L and SC628LR operate across 6 ~ 28V DC with current supply of 4 ~ 18mA. Frequency response, sound pressure level, and operating temperature ranges are identical.

Q: Which part should be selected for new product designs?

A: For new designs, SC628LR is recommended due to ROHS3 compliance, which aligns with current environmental regulations and industry standards. Both parts are active in production with adequate inventory availability.
