XL-450 Equivalent & Substitute Parts

Part Overview

The XL-450 is a piezo buzzer manufactured by PUI Audio, Inc., designed as a 12V panel-mount indicator with internal drive circuitry and flange-mounted wire leads. The component measures 28mm in diameter and is classified as obsolete. Due to its obsolete status, identifying active equivalent parts is necessary to maintain design continuity and ensure ongoing component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The XL-2835-TF-LW150-R qualifies as a direct substitute for the XL-450 based on the following alignment of critical parameters:

• Identical manufacturer (PUI Audio, Inc.) and series (XL)
• Matching technology (Piezo) and driver circuitry (Indicator, Internally Driven)
• Identical input type (DC) and rated voltage (12 V)
• Identical mounting configuration (Panel Mount, Flange)
• Identical termination method (Wire Leads)
• Matching physical dimensions (28mm diameter, 25.90mm height)

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The XL-2835-TF-LW150-R is the direct substitute for the obsolete XL-450. Selection is based on:

• Active product status ensuring continued availability and manufacturing support
• ROHS3 compliance of the substitute part, providing regulatory advantage over the non-compliant original
• Identical mechanical and electrical interface specifications
• Fully specified operational parameters (frequency, SPL, current, temperature range) providing enhanced design documentation

The substitute part maintains backward compatibility with existing mechanical mounting and electrical connections while offering improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the XL-2835-TF-LW150-R be used as a direct replacement for the XL-450?

A: Yes. Both parts share identical mounting type (Panel Mount, Flange), termination method (Wire Leads), physical dimensions (28mm diameter), rated voltage (12V), and driver circuitry (Indicator, Internally Driven). No circuit modifications or mechanical redesign is required.

Q: What are the key differences between these parts?

A: The XL-450 specifications are partially undocumented. The XL-2835-TF-LW150-R provides complete specifications including frequency (4.6kHz), SPL (95dB @ 12V, 10cm), current consumption (6mA), operating temperature range (-30°C ~ 85°C), and voltage operating range (3 ~ 28V). The substitute is ROHS3 compliant, whereas the original is non-compliant.

Q: Are there packaging differences?

A: The XL-450 packaging is listed as "-" (unspecified). The XL-2835-TF-LW150-R is supplied in Bulk packaging.

Q: Will the substitute part work with existing PCB designs?

A: Yes. Identical wire lead termination and flange mounting configuration ensure compatibility with existing designs without modification.

Q: Is the substitute part available in production quantities?

A: Yes. The XL-2835-TF-LW150-R is in active production status with documented inventory availability.
