Substitute Part Grouping Explanation

The SC616NP-BTR qualifies as a direct substitute for the SC616NP-10 based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage Range: 6–16V DC (identical)
• Frequency: 2.9kHz (identical)
• Sound Pressure Level: 80dB @ 6V, 61cm (identical)
• Technology: Piezo (identical)
• Driver Circuitry: Indicator, Internally Driven (identical)
• Operating Mode: Pulse, Fast (identical)
• Mounting Type: Panel Mount (identical)
• Size / Dimension: 1.687" Dia (42.85mm) (identical)
• Operating Temperature: –30°C to 65°C (identical)
• RoHS Status: ROHS3 Compliant (identical)

Allowable Variations:

• Current Supply: SC616NP-10 specifies 6–18mA; SC616NP-BTR specifies 6–22mA. The substitute accommodates a wider current range while maintaining backward compatibility with the original specification.
• Height – Seated (Max): SC616NP-10 is 1.946" (49.43mm); SC616NP-BTR is 1.399" (35.54mm). The substitute is physically more compact, reducing panel depth requirements.
• Termination: SC616NP-10 uses Screw Terminals; SC616NP-BTR uses Screw Terminal with Quick Connect Tab (0.250" / 6.35mm). The substitute provides enhanced connectivity options while retaining screw terminal compatibility.
• Product Status: SC616NP-10 is Obsolete; SC616NP-BTR is Active, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The SC616NP-BTR is the designated substitute for the SC616NP-10. Selection of the SC616NP-BTR is supported by the following factors:

Product Status: The SC616NP-10 is obsolete, whereas the SC616NP-BTR is active. Active product status ensures component availability, manufacturer support, and continued compliance with regulatory requirements.

Regulatory Compliance: The SC616NP-BTR carries cUL and UL approvals, providing enhanced certification coverage compared to the SC616NP-10. Both components maintain ROHS3 compliance and REACH unaffected status.

Electrical Compatibility: The SC616NP-BTR operates within the same voltage range (6–16V DC) and produces identical acoustic output (2.9kHz, 80dB SPL). The expanded current specification (6–22mA versus 6–18mA) accommodates the original design without modification.

Mechanical Compatibility: Both components share identical diameter (42.85mm) and mounting type (panel mount). The SC616NP-BTR features a reduced seated height (35.54mm versus 49.43mm), which may reduce panel depth requirements in space-constrained applications.

Termination Enhancement: The SC616NP-BTR provides dual termination options (screw terminal and quick connect tab), offering installation flexibility while maintaining backward compatibility with existing screw terminal wiring.

Frequently Asked Questions (FAQ)

Q: Can the SC616NP-BTR directly replace the SC616NP-10 in existing designs?

A: Yes. The SC616NP-BTR maintains electrical and acoustic equivalence across all critical parameters: voltage range, frequency, SPL output, operating temperature, and mounting configuration. The substitute is mechanically compatible with panel mount installations designed for the SC616NP-10.

Q: What is the significance of the current supply difference (6–18mA versus 6–22mA)?

A: The SC616NP-BTR specifies a wider current range. This variation does not affect compatibility; designs operating the SC616NP-10 within its 6–18mA specification will operate the SC616NP-BTR within its allowable range. The expanded specification provides additional design margin.

Q: Does the reduced height of the SC616NP-BTR (35.54mm versus 49.43mm) affect installation?

A: The reduced height is a dimensional improvement that decreases panel depth requirements. Existing panel cutouts and mounting hardware designed for the SC616NP-10 will accommodate the SC616NP-BTR. No design modification is necessary.

Q: What is the Quick Connect Tab on the SC616NP-BTR?

A: The SC616NP-BTR includes a 0.250" (6.35mm) quick connect tab in addition to screw terminals. This feature provides an alternative connection method for applications requiring rapid assembly or disconnection. Existing screw terminal connections remain fully functional.

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

A: The SC616NP-BTR carries cUL and UL approvals, whereas the SC616NP-10 does not list these certifications. Both components are ROHS3 compliant and REACH unaffected. The SC616NP-BTR provides enhanced regulatory coverage suitable for applications requiring UL/cUL certification.

Q: Why is the SC616NP-10 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of the part. The SC616NP-BTR is the active equivalent, ensuring ongoing availability and manufacturer support for applications requiring this buzzer specification.
