Key Parameters

Substitute Part Grouping Explanation

The AT-2460-TF-LW100-R qualifies as a direct substitute for the AT-12 based on the following alignment of critical parameters:

• Identical manufacturer (PUI Audio, Inc.) and series (AT)
• Matching technology (Piezo, externally driven transducer)
• Identical operating frequency (6kHz)
• Identical mounting configuration (Panel Mount, Flange)
• Identical termination method (Wire Leads)
• Identical mechanical form factor (24mm diameter, compatible height profile)

The AT-2460-TF-LW100-R is an active product with enhanced electrical specifications and improved compliance status, making it suitable for direct replacement in applications previously using the AT-12.

Parameter Comparison

Engineering Selection Recommendations

The AT-2460-TF-LW100-R is the designated substitute for the obsolete AT-12. Selection of this alternative is justified by:

• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance, addressing regulatory requirements not met by the AT-12
• Identical mechanical and functional form factor, enabling direct integration without redesign
• Specified electrical operating parameters (1 ~ 30V range, 10V rated) providing design flexibility
• Documented performance metrics (88dB SPL @ 10V, 10cm) enabling acoustic performance verification

Frequently Asked Questions (FAQ)

Q: Can the AT-2460-TF-LW100-R be used as a direct replacement for the AT-12?

A: Yes. Both components share identical frequency (6kHz), mounting configuration (Panel Mount, Flange), termination (Wire Leads), and mechanical dimensions (24mm diameter). The AT-2460-TF-LW100-R is mechanically and functionally compatible with applications designed for the AT-12.

Q: What is the height difference between these components?

A: The AT-12 has a maximum seated height of 0.157" (4.00mm), while the AT-2460-TF-LW100-R measures 0.177" (4.50mm). This 0.020" (0.50mm) difference must be evaluated for clearance in space-constrained applications.

Q: Does the AT-2460-TF-LW100-R meet RoHS requirements?

A: Yes. The AT-2460-TF-LW100-R is ROHS3 compliant, whereas the AT-12 is RoHS non-compliant. This makes the substitute suitable for applications with RoHS regulatory requirements.

Q: What voltage should be applied to the AT-2460-TF-LW100-R?

A: The AT-2460-TF-LW100-R operates across a 1 ~ 30V range with a rated voltage of 10V. The specific voltage selection depends on the application circuit design and desired acoustic output.

Q: Are there any packaging differences?

A: The AT-12 packaging is not specified in available documentation. The AT-2460-TF-LW100-R is supplied in Bulk packaging with 1000 pieces per order unit.
