Equivalent & Substitute Parts for 3AC-F

Part Overview

The 3AC-F is an amber LED indicator manufactured by Bivar Inc., designed for through-hole mounting applications requiring discrete 2V amber indication. This component features a clear lens with 40mcd brightness rating and 30° viewing angle in a standard T-1 (3mm) package format.

The 3AC-F is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this LED indicator is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3AC-F are identified based on the following core compatibility parameters:

Primary Compatibility Criteria:

• Color: Amber
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf): 2V nominal (tolerance range 2.0V to 2.1V acceptable)
• Current - Test: 20mA
• Wavelength - Peak: 605nm region

Secondary Consideration:

• Product Status: Active status preferred for long-term availability

The three substitute parts listed (3AD-F, HLMP-Y701-G0000, SSL-LX3044AC) meet the primary compatibility criteria. Variations in millicandela rating, viewing angle, and lens transparency represent acceptable trade-offs within the amber LED indicator category, provided the application circuit accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

3AD-F (Bivar Inc.): This substitute maintains identical forward voltage (2V), current rating (20mA), and physical dimensions (5.30mm height) to the 3AC-F. The primary difference is diffused lens transparency versus clear, resulting in lower millicandela output (25mcd versus 40mcd). This part is active and ROHS3 compliant. Selection is appropriate where reduced brightness is acceptable or where diffused light distribution is preferred.

HLMP-Y701-G0000 (Broadcom Limited): This substitute provides clear lens transparency matching the 3AC-F and maintains 2V forward voltage and 20mA test current. The millicandela rating is significantly higher (400mcd versus 40mcd), and viewing angle is wider (45° versus 30°). Height is marginally lower (5.20mm versus 5.30mm). This part is active and ROHS3 compliant. Selection is appropriate where higher brightness is required or where wider viewing angle improves visibility.

SSL-LX3044AC (Lumex Opto/Components Inc.): This substitute provides clear lens transparency and 605nm peak wavelength matching the 3AC-F. Forward voltage is slightly elevated (2.1V versus 2V nominal). Millicandela rating is double the 3AC-F (80mcd versus 40mcd). Viewing angle matches at 30°. Height is slightly greater (5.73mm versus 5.30mm). This part is active and ROHS3 compliant. Selection is appropriate where moderate brightness increase is needed and the 0.1V forward voltage difference is accommodated by circuit design.

All three substitutes are ROHS3 compliant and carry MSL rating of 1 (Unlimited), matching the environmental classification of the 3AC-F.

Frequently Asked Questions (FAQ)

Q: Can the 3AD-F replace the 3AC-F in all applications?

A: The 3AD-F is mechanically and electrically compatible (same 2V, 20mA, T-1 package, 5.30mm height). However, the diffused lens reduces brightness from 40mcd to 25mcd. Substitution is valid only if the application circuit and optical design accommodate lower brightness output.

Q: What is the primary difference between the HLMP-Y701-G0000 and the 3AC-F?

A: Both feature clear lenses and 2V forward voltage. The HLMP-Y701-G0000 provides 10 times higher brightness (400mcd versus 40mcd) and a wider viewing angle (45° versus 30°). The height is 0.1mm lower. This substitute is suitable for applications requiring enhanced visibility.

Q: Is the SSL-LX3044AC compatible with the 3AC-F circuit design?

A: The SSL-LX3044AC is compatible with minor circuit considerations. Forward voltage is 2.1V versus 2V, a 0.1V difference that may require resistor adjustment in current-limiting circuits. Brightness is doubled (80mcd versus 40mcd). Physical height is 0.43mm greater. Compatibility depends on circuit tolerance and mechanical clearance.

Q: Why is the 3AC-F listed as obsolete?

A: The 3AC-F is classified as obsolete by the manufacturer. The three active substitutes (3AD-F, HLMP-Y701-G0000, SSL-LX3044AC) provide equivalent or enhanced functionality and are recommended for new designs and ongoing production.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three substitute parts (3AD-F, HLMP-Y701-G0000, SSL-LX3044AC) are ROHS3 compliant. The 3AC-F compliance status is not specified in available documentation.

Q: What is the viewing angle significance when selecting a substitute?

A: Viewing angle determines the cone of light visibility. The 3AC-F has 30° viewing angle. The 3AD-F (35°) and HLMP-Y701-G0000 (45°) provide wider light distribution, suitable for applications requiring visibility from multiple angles. The SSL-LX3044AC matches the 30° specification. Selection depends on the intended mounting position and observer angle requirements.

Q: Can multiple substitutes be used interchangeably in the same design?

A: No. Each substitute has distinct electrical and optical characteristics. Once a substitute is selected and the circuit is designed around its specifications (forward voltage, brightness, viewing angle), that specific part should be used consistently. Mixing substitutes in production introduces performance variability.
