Substitute Part Grouping Explanation
Substitution eligibility for the XL-450-1 is determined by the following critical parameters:
- Voltage Rating: Rated voltage must be 12V DC to ensure direct compatibility with existing circuit designs
- Frequency: Operating frequency must be 4.6kHz to maintain signal integrity and system timing requirements
- Technology: Piezo technology is required for acoustic performance consistency
- Driver Circuitry: Internally driven indicator configuration ensures no external driver circuit modifications are necessary
- Mounting Configuration: Panel mount flange with wire lead termination must be preserved for mechanical and electrical interface compatibility
- Physical Dimensions: 28mm diameter housing with compatible height specifications ensures proper panel cutout and installation fit
The AI-2835-TF-LW150-3-R meets all substitution criteria as an active product from the same manufacturer with identical core electrical and mechanical specifications.

Engineering Selection Recommendations
The AI-2835-TF-LW150-3-R is the direct substitute for the obsolete XL-450-1. Selection is based on the following engineering factors:
Product Status: The XL-450-1 is obsolete and no longer manufactured. The AI-2835-TF-LW150-3-R is an active product with confirmed inventory availability (819 pcs in stock), ensuring supply chain continuity.
Electrical Compatibility: Both components share identical rated voltage (12V), frequency (4.6kHz), technology (Piezo), and driver configuration (Internally Driven Indicator). The AI-2835-TF-LW150-3-R operates across a wider voltage range (3~28V), providing enhanced flexibility for applications with variable supply voltages while maintaining full compatibility at the 12V nominal rating.
Mechanical Compatibility: Both components feature identical 28mm diameter flange mounting and wire lead termination. The AI-2835-TF-LW150-3-R height (25.50mm) is marginally shorter than the XL-450-1 (25.90mm), which is compatible with standard panel cutout specifications and does not require mechanical redesign.
Compliance: The AI-2835-TF-LW150-3-R meets ROHS3 compliance standards, whereas the XL-450-1 is RoHS non-compliant. For applications subject to current environmental regulations or procurement standards, the substitute component satisfies modern compliance requirements.
Performance Specifications: The AI-2835-TF-LW150-3-R provides documented performance parameters (100dB SPL @ 12V/10cm, 10mA supply current, -20°C to 60°C operating temperature) that were not specified for the obsolete XL-450-1, enabling more precise system design and validation.
Frequently Asked Questions (FAQ)
Q: Can the AI-2835-TF-LW150-3-R be used as a direct replacement for the XL-450-1 without circuit modifications?
A: Yes. Both components are rated for 12V DC operation, share identical 4.6kHz frequency, and feature the same panel mount flange configuration with wire lead termination. No circuit modifications are required for direct substitution.
Q: What is the significance of the wider voltage range (3~28V) in the AI-2835-TF-LW150-3-R?
A: The substitute component operates across a broader voltage range while maintaining the same 12V rated specification. This provides design flexibility for applications with variable supply voltages. At the nominal 12V operating point, performance is equivalent to the original XL-450-1.
Q: Are there mechanical differences between the two components?
A: Both components have identical 28mm diameter flanges and wire lead termination. The AI-2835-TF-LW150-3-R is 0.4mm shorter in seated height (25.50mm vs. 25.90mm). This minor difference is within standard panel cutout tolerances and does not require mechanical redesign.
Q: What is the difference in RoHS compliance status?
A: The XL-450-1 is RoHS non-compliant, while the AI-2835-TF-LW150-3-R is ROHS3 compliant. For applications subject to environmental regulations or modern procurement standards, the substitute meets current compliance requirements.
Q: Is the AI-2835-TF-LW150-3-R available in the same packaging as the XL-450-1?
A: The XL-450-1 packaging specification was not provided in the original documentation. The AI-2835-TF-LW150-3-R is available in Bulk packaging with 819 pcs currently in stock.
Q: What performance data is available for the AI-2835-TF-LW150-3-R?
A: The substitute component is specified at 100dB SPL @ 12V/10cm with 10mA supply current and -20°C to 60°C operating temperature range. These parameters were not documented for the obsolete XL-450-1.
