Equivalent & Substitute Parts for 5AC12V-F

Part Overview

The 5AC12V-F is an amber LED indicator manufactured by Bivar Inc., designed for 12V discrete radial applications in through-hole mounting configurations. This component features a 5mm T-1 3/4 lens with clear transparency and 40mcd brightness rating. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5AC12V-F is determined by strict alignment with the following critical parameters:

Critical Parameters (Must Match):

• Forward voltage of 12V for direct circuit compatibility
• Amber color for consistent visual indication
• 5mm T-1 3/4 lens size for mechanical fit
• Through-hole radial mounting for PCB assembly compatibility

Important Parameters (Should Align):

• Current rating within acceptable circuit design range
• Brightness (millicandela) sufficient for intended application visibility
• Viewing angle appropriate for installation context
• Physical height compatible with enclosure clearance

The substitute part 4302H3-12V meets all critical parameters while presenting variations in secondary characteristics that may affect performance in specific applications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 4302H3-12V from Visual Communications Company is electrically and mechanically compatible as a substitute for the obsolete 5AC12V-F based on matching critical parameters: 12V forward voltage, amber color, 5mm T-1 3/4 through-hole radial package.

Key Considerations:

1. Brightness Reduction: The 4302H3-12V operates at 8mcd compared to the original 40mcd. This represents an 80% reduction in brightness. Applications requiring high visibility or long-distance indication may be affected.

2. Lens Characteristics: The substitute features a diffused amber lens versus the original clear colorless lens. This changes light distribution and color saturation characteristics. The diffused design provides a wider 60° viewing angle compared to the original 35°, which may improve visibility in certain mounting orientations.

3. Current Draw: The substitute draws 13mA versus the original 10mA, representing a 30% increase in circuit current. Verify that existing current-limiting resistors and power supply capacity accommodate this increase.

4. Physical Height: The substitute is 1.48mm taller (10.08mm vs. 8.60mm). Confirm clearance within enclosures and against adjacent components.

5. Wavelength Shift: The substitute operates at 583nm peak wavelength versus 605nm for the original. Both remain within the amber spectrum but represent different color points.

6. Product Status: The 4302H3-12V is active production status, ensuring ongoing availability and supply chain stability compared to the obsolete original.

7. Compliance: Both components share identical ECCN (EAR99), HTSUS (8541.41.0000), and MSL (1) classifications. The substitute is RoHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 4302H3-12V directly replace the 5AC12V-F without circuit modifications?

A: The 4302H3-12V is electrically compatible at the 12V forward voltage level. However, the 30% increase in test current (13mA vs. 10mA) requires verification that existing current-limiting resistors and power supply capacity are adequate. No circuit modifications are typically necessary if the original design included appropriate margin.

Q: What is the impact of the 80% brightness reduction?

A: The 4302H3-12V produces 8mcd versus the original 40mcd. This significantly reduces brightness. Applications requiring high visibility, long-distance indication, or operation in bright ambient light may not perform adequately with the substitute. Evaluate the specific visibility requirements of your application.

Q: Why does the substitute have a different lens transparency?

A: The 4302H3-12V features a diffused amber lens, while the original has a clear colorless lens. The diffused design scatters light more broadly, resulting in the wider 60° viewing angle compared to the original 35°. This affects both light distribution and color saturation. The diffused design may be preferable in applications where wide-angle visibility is required.

Q: Is the 1.48mm height difference significant?

A: The substitute is 1.48mm taller (10.08mm vs. 8.60mm). This may be significant in space-constrained applications or where clearance against enclosure lids or adjacent components is limited. Verify physical clearance in your specific installation.

Q: Are there any compliance or regulatory differences?

A: Both components share identical export control (EAR99), tariff (8541.41.0000), and moisture sensitivity (MSL 1) classifications. The substitute is RoHS3 compliant and REACH unaffected, providing equivalent regulatory status.

Q: What is the wavelength difference between 605nm and 583nm?

A: Both wavelengths fall within the amber spectrum. The 605nm original is slightly more orange-tinted, while the 583nm substitute is slightly more yellow-tinted. Both are visually amber. The difference is typically imperceptible in most applications but may be relevant in color-critical indication systems.

Q: Is the 4302H3-12V suitable for new designs?

A: Yes. The 4302H3-12V is active production status from an established manufacturer (VCC). It meets all critical substitution parameters and is suitable for both replacement of obsolete units and new design implementations, subject to the performance considerations noted above.

Q: What inventory status should I consider?

A: The original 5AC12V-F has 788 pieces in stock but is obsolete. The 4302H3-12V has 1320 pieces in stock and is active production, providing superior long-term supply chain security.
