PUI Audio X-23 Equivalent & Substitute Parts

Part Overview

The PUI Audio X-23 is an internally driven piezo buzzer rated for 12V DC operation with a 2.8kHz frequency output, designed for panel mount applications. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The X-23 series represents a legacy indicator buzzer technology that requires functional equivalents for procurement and maintenance purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the X-23 is determined by the following critical parameters:

• Voltage Rating: Rated voltage must be 12V with compatible voltage range tolerance
• Frequency: Operating frequency must be 2.8kHz to maintain system audio characteristics
• Driver Circuitry: Must be internally driven indicator type, eliminating external driver requirements
• Technology: Piezo-based construction required for acoustic performance consistency
• Mounting Type: Panel mount configuration mandatory for mechanical compatibility
• Input Type: DC operation required for power supply compatibility

The AI-4028-P-SP32-R meets all substitution criteria as an active product from the same manufacturer with identical core electrical specifications and compatible mechanical interface.

Engineering Selection Recommendations

The AI-4028-P-SP32-R is the direct substitute for the obsolete X-23. Selection is based on:

• Product Status: The AI-4028-P-SP32-R maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The substitute achieves ROHS3 compliance, addressing modern regulatory requirements that the X-23 does not meet
• Electrical Equivalence: Identical rated voltage (12V) and frequency (2.8kHz) specifications ensure functional compatibility without circuit modification
• Mechanical Compatibility: Panel mount configuration and screw terminal termination provide direct installation compatibility
• Enhanced Specifications: The AI-4028-P-SP32-R provides documented performance metrics (98dB SPL, 9mA supply current, -20°C ~ 60°C operating range) and extended voltage range (4 ~ 32V) that exceed the X-23 baseline

Frequently Asked Questions (FAQ)

Q: Can the AI-4028-P-SP32-R directly replace the X-23 without circuit modifications?

A: Yes. Both components share identical rated voltage (12V), frequency (2.8kHz), driver circuitry (internally driven indicator), and mounting type (panel mount). No circuit redesign is required.

Q: What is the primary reason for substitution?

A: The X-23 is obsolete. The AI-4028-P-SP32-R is an active product from the same manufacturer with equivalent electrical specifications and improved regulatory compliance (ROHS3).

Q: Are there mechanical compatibility concerns?

A: The AI-4028-P-SP32-R uses screw terminal and quick connect tab termination (0.187" / 4.75mm). Verify that existing panel mount holes and terminal connections accommodate the 40mm x 40mm footprint and 24.6mm seated height.

Q: Does the extended voltage range (4 ~ 32V) of the AI-4028-P-SP32-R affect compatibility?

A: No. The extended range is a superset of the 12V rated specification. The component operates at 12V as required without modification.

Q: What compliance advantage does the AI-4028-P-SP32-R provide?

A: The AI-4028-P-SP32-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The X-23 is RoHS non-compliant.

Q: Is packaging a consideration for this substitution?

A: The AI-4028-P-SP32-R is supplied in bulk packaging. Verify that bulk quantities meet procurement requirements or confirm availability in alternative packaging configurations.
