CS-3224 Equivalent & Substitute Parts

Part Overview

The CS-3224 is a magnetically driven buzzer indicator manufactured by CUI Devices, rated for 24V DC operation with an internal driver circuit. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The CS-3224 delivers 76dB sound pressure level at 30cm distance with a 20mA supply current and is designed for through-hole mounting with PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

The CS-3624 qualifies as a functional substitute for the CS-3224 based on the following alignment of critical electrical and mechanical parameters:

Electrical Compatibility:

• Both parts operate at the same rated voltage (24V DC) with identical voltage range (20 ~ 28V)
• Both utilize internally driven magnetic technology with single-tone operating mode
• Both are DC input devices with equivalent driver circuitry classification

Mechanical and Compliance Considerations:

• Both parts are manufactured by CUI Devices within the same CS series
• Both maintain RoHS compliance status (CS-3224: RoHS Compliant; CS-3624: ROHS3 Compliant)
• Both have MSL rating of 1 (Unlimited), indicating equivalent moisture sensitivity handling
• Both share identical ECCN and HTSUS classifications

Substitution Limitations: The CS-3624 differs in mounting configuration (Panel Mount, Flange vs. Through Hole), termination type (Wire Leads vs. PC Pins), physical dimensions, current draw (35mA vs. 20mA), and sound pressure level (78dB vs. 76dB). These differences require circuit board redesign and mechanical integration modifications.

Parameter Comparison

Engineering Selection Recommendations

The CS-3624 is an active product with current manufacturing support, whereas the CS-3224 is obsolete. For new designs or system refreshes, the CS-3624 is the appropriate selection from the CUI Devices CS series. Both parts maintain equivalent regulatory compliance under RoHS and REACH frameworks.

The CS-3624 provides an extended operating temperature range (-30°C to 70°C versus -20°C to 60°C), offering broader environmental tolerance. The increased sound pressure level (78dB versus 76dB) may provide improved auditory feedback in applications requiring higher acoustic output.

Circuit integration requires accommodation of the higher supply current (35mA versus 20mA). Board layout modifications are mandatory due to the transition from through-hole PC pin termination to panel-mount flange with wire leads. Mechanical enclosure design must account for the different mounting methodology and comparable dimensional footprint.

Frequently Asked Questions (FAQ)

Q: Can the CS-3624 be used as a direct drop-in replacement for the CS-3224?

A: No. While both parts share identical electrical ratings (24V DC, 20-28V range, internally driven magnetic technology), they differ in mounting type, termination style, and physical configuration. The CS-3224 uses through-hole PC pins for PCB mounting, whereas the CS-3624 requires panel-mount flange installation with wire leads. Circuit board redesign and mechanical integration modifications are necessary.

Q: What are the key electrical parameters that make the CS-3624 compatible with CS-3224 applications?

A: Both parts operate at 24V rated voltage with identical 20-28V operating range, use DC input with internally driven magnetic technology, and operate in single-tone mode. These parameters ensure functional equivalence in the electrical domain. However, the CS-3624 draws 35mA compared to the CS-3224's 20mA, requiring power supply capacity verification.

Q: Does the CS-3624 meet the same compliance standards as the CS-3224?

A: Both parts maintain RoHS compliance (CS-3224: RoHS Compliant; CS-3624: ROHS3 Compliant) and share identical ECCN (EAR99) and HTSUS (8531.80.9041) classifications. The CS-3624 includes REACH Unaffected status. Compliance requirements are satisfied for both parts.

Q: What is the impact of the different sound pressure levels?

A: The CS-3624 produces 78dB at 24V and 30cm, compared to the CS-3224's 76dB. This 2dB increase represents a perceptible improvement in acoustic output suitable for applications requiring higher auditory alert levels. System acoustic design should account for this difference.

Q: How does the increased current draw of the CS-3624 affect circuit design?

A: The CS-3624 requires 35mA supply current versus the CS-3224's 20mA. Power supply and current-limiting circuitry must be sized accordingly. Verify that existing power distribution infrastructure can accommodate the additional 15mA load without exceeding voltage regulation specifications.

Q: Are there packaging or inventory considerations for the CS-3624?

A: The CS-3624 is actively manufactured and available in tray packaging with 1145 pieces in current stock. The CS-3224 is obsolete with limited remaining inventory (883 pieces). For production continuity, the CS-3624 is the recommended selection.
