Key Parameters

Substitute Part Grouping Explanation

The CST-934AS qualifies as a functional substitute for the CSQ-706BS based on the following critical parameters:

Electrical Compatibility: Both components operate as externally driven magnetic transducers with identical rated voltage (3V), matching sound pressure level output (90dB @ 3V, 5cm), and compatible frequency response within the audible range (2kHz vs. 2.73kHz). The CST-934AS operates at 80mA versus the CSQ-706BS at 90mA, representing a 10mA reduction in supply current.

Mechanical Compatibility: Both components feature custom spring terminals and top port location, enabling direct integration into existing circuit designs. The CST-934AS uses a smaller 9mm diameter form factor compared to the 12mm diameter of the CSQ-706BS, with a marginal height increase (4.70mm vs. 4.20mm).

Environmental & Compliance Alignment: Both components maintain identical operating temperature range (-20°C ~ 60°C), washable ratings, and RoHS compliance status. The CST-934AS carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory support.

Engineering Selection Recommendations

The CST-934AS is the designated substitute for the obsolete CSQ-706BS. Selection of the CST-934AS is supported by:

Product Status: The CST-934AS maintains active product status with established supply chain availability, whereas the CSQ-706BS is classified as obsolete with no ongoing manufacturing support.

Regulatory Compliance: The CST-934AS carries ROHS3 compliance, representing the current regulatory standard, compared to the legacy RoHS Compliant designation of the CSQ-706BS. Both components maintain REACH Unaffected and EAR99 ECCN classifications.

Electrical Performance: Both components deliver identical sound pressure level output (90dB @ 3V, 5cm) and operate within compatible voltage and frequency parameters. The CST-934AS exhibits reduced supply current (80mA vs. 90mA), providing marginal power efficiency improvement.

Mechanical Integration: The CST-934AS employs a smaller 9mm diameter form factor, which may require PCB layout verification in space-constrained applications. The height differential (4.70mm vs. 4.20mm) is negligible for most mounting scenarios. Both components utilize identical spring terminal termination and custom mounting specifications.

Frequently Asked Questions (FAQ)

Q: Can the CST-934AS directly replace the CSQ-706BS without circuit modification?

A: The CST-934AS is electrically compatible with the CSQ-706BS when operated at the rated 3V voltage. Both components are externally driven magnetic transducers with identical SPL output and compatible frequency response. PCB layout verification is required due to the reduced 9mm diameter form factor of the CST-934AS compared to the 12mm diameter of the CSQ-706BS.

Q: What is the primary difference in electrical performance between these components?

A: The CST-934AS operates at 80mA supply current versus 90mA for the CSQ-706BS, representing a 10mA reduction. Both components deliver 90dB SPL at 3V and 5cm. The CST-934AS operates across a wider voltage range (2 ~ 4.5V) compared to the CSQ-706BS (1 ~ 3V).

Q: Are there packaging differences between the CSQ-706BS and CST-934AS?

A: The CSQ-706BS is supplied in standard packaging, while the CST-934AS is supplied in Tray packaging. Both components feature identical spring terminal termination and custom mounting specifications.

Q: What compliance certifications apply to the CST-934AS?

A: The CST-934AS carries ROHS3 Compliant status, REACH Unaffected designation, and EAR99 ECCN classification. These certifications align with current regulatory requirements for electronic components.

Q: Is the CST-934AS suitable for applications with space constraints?

A: The CST-934AS features a 9mm diameter form factor, which is 3mm smaller than the CSQ-706BS 12mm diameter. Applications with limited horizontal space may benefit from this reduced footprint. The height increase (4.70mm vs. 4.20mm) is minimal and typically does not impact vertical clearance requirements.
