Equivalent & Substitute Parts: 3AC12V-F

Part Overview

The 3AC12V-F is an amber LED indication component manufactured by Bivar Inc., designed for discrete 12V radial applications in through-hole mounting configurations. This T-1 (3mm) form factor LED features a clear, domed lens and operates at 10mA test current with a 40 millicandela brightness rating. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3AC12V-F must satisfy the following critical parameters to ensure functional equivalence:

Mandatory Matching Criteria:

• Color: Amber
• Lens Transparency: Clear
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Voltage - Forward (Vf) (Typ): 12V
• Current - Test: 10mA
• Mounting Type: Through Hole
• Package / Case: Radial
• Supplier Device Package: T-1 (3mm)
• Wavelength - Peak: 605nm

Performance Parameters:

• Millicandela Rating: 40mcd
• Viewing Angle: 20°
• Height (Max): 5.30mm

Substitute components must maintain identical electrical specifications (12V forward voltage, 10mA test current), physical form factor (T-1 radial through-hole), and optical characteristics (amber color, clear lens, 605nm peak wavelength, 40mcd brightness). Deviations in any of these parameters result in incompatibility with the original circuit design and application requirements.

Parameter Comparison

No substitute parts have been provided in the input data. The comparison table cannot be populated without equivalent or alternative part numbers meeting the specified criteria.

Engineering Selection Recommendations

The 3AC12V-F is designated as obsolete. Component selection for replacement applications must prioritize parts with identical electrical and mechanical specifications to ensure direct substitution without circuit redesign or board layout modification.

Selection criteria are based on:

1. Product Status Alignment: Substitute parts should be active or standard production status to ensure long-term availability and supply chain stability.

2. Electrical Compatibility: Forward voltage (12V), test current (10mA), and peak wavelength (605nm) must match exactly to maintain circuit performance and brightness characteristics.

3. Physical Form Factor: T-1 (3mm) radial through-hole package with 5.30mm maximum height ensures mechanical compatibility with existing printed circuit board designs.

4. Optical Specifications: Amber color, clear lens, round domed top, 40mcd brightness, and 20° viewing angle must be preserved for application-specific indication requirements.

5. Compliance and Certification: Moisture Sensitivity Level 1 (Unlimited) classification applies to all qualifying substitutes.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the 3AC12V-F?

A: A valid substitute must match all critical parameters: 12V forward voltage, 10mA test current, amber color, clear lens, T-1 (3mm) form factor, radial through-hole mounting, 605nm peak wavelength, 40mcd brightness rating, and 20° viewing angle. Any deviation in these specifications indicates incompatibility.

Q: Can I use a different lens color or transparency?

A: No. The 3AC12V-F specifies a colorless lens with clear transparency. Substitutes with tinted, diffused, or opaque lenses will alter the optical output and are not equivalent.

Q: Is the T-1 (3mm) package interchangeable with other LED form factors?

A: No. The T-1 (3mm) radial through-hole package is specific to this component. T-1¾, T-2, or surface-mount alternatives have different physical dimensions and mounting requirements and are not direct substitutes.

Q: What is the significance of the 605nm peak wavelength?

A: The 605nm wavelength defines the amber color output. This specification must be matched exactly in substitute parts to maintain consistent indication color across the application.

Q: Does the 40mcd brightness rating have substitution flexibility?

A: No. The 40mcd rating is a core performance specification. Substitutes with higher or lower brightness ratings will alter the visual indication intensity and are not equivalent.

Q: Why is the 20° viewing angle important for substitution?

A: The 20° viewing angle determines the directional visibility of the LED indication. Substitutes with wider or narrower viewing angles will change the application's visibility characteristics and are not compatible.

Q: Can I substitute this part with a modern surface-mount LED?

A: No. The 3AC12V-F is a through-hole radial component. Surface-mount alternatives require different board layout, mounting techniques, and assembly processes and are not direct substitutes.

Q: What does Moisture Sensitivity Level 1 mean for storage and handling?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. This component can be stored and handled under standard conditions without special moisture control measures.
