X-10W Piezo Buzzer Equivalent & Substitute Parts

Part Overview

The X-10W is an internally driven piezo buzzer manufactured by PUI Audio, Inc., rated for 12V DC operation at 4.6kHz frequency with a 40x40mm form factor. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The X-4035-TFL-LW140-R qualifies as a direct substitute for the X-10W based on the following critical parameters:

• Identical rated voltage: 12V DC
• Identical frequency: 4.6kHz
• Identical technology: Piezo with internally driven indicator circuitry
• Identical physical dimensions: 40x40mm form factor with 0.339" maximum seated height
• Identical termination: Wire leads with custom mounting configuration
• Identical input type: DC operation

The X-4035-TFL-LW140-R is an active product with enhanced specifications including defined voltage range (3-20V), specified current consumption (8mA), documented sound pressure level (99dB @ 12V, 10cm), and operating temperature range (-30°C to 80°C). These enhancements do not conflict with the X-10W application requirements and provide additional design margin.

Parameter Comparison

Engineering Selection Recommendations

The X-4035-TFL-LW140-R is the direct equivalent for X-10W replacement. Selection is based on:

• Functional equivalence across all critical electrical parameters (voltage, frequency, driver type, input specification)
• Mechanical compatibility with identical form factor and termination
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance of the substitute part, providing regulatory advantage over the obsolete non-compliant original
• Enhanced specification documentation (voltage range, current, SPL, temperature range) supporting design validation without functional deviation from the original application

No design modifications are required for substitution. The X-4035-TFL-LW140-R operates within the same electrical and mechanical envelope as the X-10W.

Frequently Asked Questions (FAQ)

Q: Can the X-4035-TFL-LW140-R be used as a direct replacement for X-10W without circuit modification?

A: Yes. Both components share identical rated voltage (12V), frequency (4.6kHz), driver circuitry (internally driven indicator), input type (DC), and physical dimensions (40x40mm). No circuit changes are required.

Q: What is the primary reason for substitution?

A: The X-10W is obsolete. The X-4035-TFL-LW140-R is an active product from the same manufacturer with identical core specifications and enhanced compliance status.

Q: Are there differences in electrical performance between these parts?

A: The X-4035-TFL-LW140-R provides documented specifications for current consumption (8mA), sound pressure level (99dB @ 12V, 10cm), and operating temperature range (-30°C to 80°C). The X-10W does not specify these parameters. Both operate at the same rated voltage and frequency.

Q: Does the substitute part have different packaging?

A: The X-10W packaging is listed as "-" (unspecified). The X-4035-TFL-LW140-R is supplied in Bulk packaging. Both use identical wire lead termination and custom mounting configuration.

Q: Is the substitute part RoHS compliant?

A: Yes. The X-4035-TFL-LW140-R is ROHS3 compliant, whereas the X-10W is RoHS non-compliant. This represents a regulatory improvement for new designs and updated production runs.

Q: What is the voltage operating range of the substitute?

A: The X-4035-TFL-LW140-R operates across 3V to 20V, with 12V as the rated voltage. The X-10W specifies only 12V rated voltage with no range provided.
