Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3SGC-201 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color: Green
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf) Typical: 2.1V (±0.05V tolerance acceptable)
• Current - Test: 20mA (or compatible test current)
• Lens Transparency: Clear

Secondary Compatibility Parameters:

• Wavelength - Peak: 568nm to 575nm range
• Viewing Angle: 20° to 45°
• Height (Max): 5.10mm to 6.30mm
• Millicandela Rating: 25mcd to 320mcd
• Moisture Sensitivity Level: 1 (Unlimited)

Parametric Equivalent: The 3SGC-F from Bivar Inc. is a direct parametric equivalent with identical electrical and optical specifications, differing only in product status (Active) and packaging format (Bulk).

Similar Substitutes: Parts from Lite-On Inc., Fairchild Semiconductor, Broadcom Limited, and Rohm Semiconductor meet the primary substitution criteria with minor variations in millicandela rating, viewing angle, or height that remain within acceptable operational ranges for standard indication applications.

Non-Equivalent Parts: The 151031VS04000 (Würth Elektronik) and 264-7SYGC/S530-E2 (Everlight Electronics) feature diffused lens transparency and yellow-green coloration, respectively, and are classified as similar but not direct substitutes due to optical property differences.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitute: 3SGC-F (Bivar Inc.)

The 3SGC-F is the optimal substitute for the obsolete 3SGC-201. It maintains identical electrical specifications (2.1V forward voltage, 20mA test current), optical properties (green color, clear lens, 568nm peak wavelength), and mechanical form factor (3mm T-1 through-hole radial package). The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Height variance of 0.20mm (5.30mm vs. 5.10mm) is negligible for standard PCB assembly applications.

Secondary Substitutes for Higher Brightness Applications:

HLMP-Y801-JPP00 (Broadcom Limited) and LTL1CHKGKNN (Lite-On Inc.) are suitable alternatives when increased luminous intensity is required. Both deliver 310mcd and 320mcd respectively, compared to the original 50mcd specification. Both maintain 2.1V/2.05V forward voltage compatibility and 20mA test current. HLMP-Y801-JPP00 provides a narrower 30° viewing angle, while LTL1CHKGKNN offers a wider 45° viewing angle. Both are ROHS3 compliant and in active production.

Substitutes for Standard Brightness Maintenance:

MV7442 (Fairchild Semiconductor) and LTL-4236N (Lite-On Inc.) provide moderate brightness increases (120mcd and 40mcd respectively) while maintaining 2.1V forward voltage and 20mA test current compatibility. MV7442 offers a 45° viewing angle with ROHS3 compliance. LTL-4236N operates at 10mA test current with a 45° viewing angle and ROHS3 compliance.

Not Recommended for Direct Substitution:

SLR-343MC3F (Rohm Semiconductor) is classified as "Not For New Designs" and should not be selected for new applications despite meeting primary substitution criteria.

151031VS04000 (Würth Elektronik) features diffused lens transparency, altering optical characteristics unsuitable for clear indication applications.

264-7SYGC/S530-E2 (Everlight Electronics) is yellow-green rather than pure green and operates at 2V forward voltage, introducing color and electrical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3SGC-F directly replace the 3SGC-201 without circuit modification?

A: Yes. The 3SGC-F is a parametric equivalent with identical forward voltage (2.1V), test current (20mA), color (green), lens transparency (clear), and package type (3mm T-1 radial through-hole). The 0.20mm height difference (5.30mm vs. 5.10mm) does not require circuit redesign for standard PCB applications.

Q: What is the difference between "Parametric Equivalent" and "Similar Substitute"?

A: A parametric equivalent maintains all critical electrical and optical specifications within the same tolerance range. The 3SGC-F is a parametric equivalent. Similar substitutes meet primary substitution criteria (color, package, voltage, current) but may vary in secondary parameters such as millicandela rating, viewing angle, or wavelength within acceptable operational ranges for the application.

Q: Why are 151031VS04000 and 264-7SYGC/S530-E2 listed but not recommended?

A: These parts are listed because they appear in the original 3SGC-201 substitute cross-reference data. However, 151031VS04000 features diffused lens transparency (vs. clear), and 264-7SYGC/S530-E2 is yellow-green (vs. pure green). These optical differences make them unsuitable for direct substitution in applications requiring clear green indication.

Q: Can I use HLMP-Y801-JPP00 if my circuit is designed for 50mcd brightness?

A: HLMP-Y801-JPP00 delivers 310mcd, significantly exceeding the original 50mcd specification. While electrically compatible (2.1V, 20mA), the increased brightness may cause visual glare or require circuit-level current limiting adjustments. Verify application requirements before substitution.

Q: What does "Not For New Designs" mean for SLR-343MC3F?

A: This product status indicates the manufacturer is not recommending this part for new circuit designs. While the component may still be available and functional, Rohm Semiconductor has designated it as end-of-life or superseded. New designs should select from active-status alternatives such as 3SGC-F, HLMP-Y801-JPP00, or LTL1CHKGKNN.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. The 3SGC-F, HLMP-Y801-JPP00, LTL-4236N, LTL1CHKGKNN, and MV7442 are all ROHS3 compliant. SLR-343MC3F is also ROHS3 compliant but carries "Not For New Designs" status.

Q: What is the significance of Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. All recommended substitutes maintain MSL 1 rating except MV7442, which carries MSL 3 (168 Hours), requiring controlled storage and handling within 168 hours of package opening.

Q: Can I mix different substitute parts in the same production batch?

A: Substitutes with identical electrical specifications (2.1V, 20mA) and optical properties (green, clear lens, 568nm wavelength range) are interchangeable within the same circuit. However, parts with different millicandela ratings (e.g., 50mcd vs. 310mcd) will produce visually inconsistent brightness across the assembly. Maintain part number consistency within a single production lot for uniform appearance.
