3SUGC-F Green LED Through-Hole Equivalent & Substitute Parts

Part Overview

The 3SUGC-F is a green LED indication component manufactured by Bivar Inc., configured as a discrete 2.1V radial through-hole device in T-1 form factor. This is an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Alternative models become necessary when the primary part experiences supply constraints, inventory limitations, or design requirement adjustments within the allowed electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

Substitution of the 3SUGC-F is determined by the following critical parameters:

Color: Must be Green
Mounting Type: Must be Through Hole (Radial configuration)
Package Form: Must be T-1 or equivalent 3mm through-hole package
Voltage - Forward (Vf): 2.0V to 2.1V range
Current - Test: 10mA to 20mA operating range
Lens Transparency: Clear or Diffused acceptable
Physical Height: Compatible with PCB assembly constraints (5.2mm to 5.85mm maximum)
Compliance: ROHS3 Compliant required

The six qualified substitute parts meet these criteria while maintaining functional compatibility within allowed electrical and mechanical tolerances.

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

HLMP-Y801-JPP00 (Broadcom Limited): Matches clear lens transparency, identical T-1 package, 310mcd brightness specification, and active product status. Voltage and current parameters align with the primary component.
LTL1CHKGKNN (Lite-On Inc.): Provides highest brightness rating at 320mcd with clear lens transparency, T-1 package compatibility, and active product status. Forward voltage of 2.05V operates within functional range.

Secondary Substitutes (Active Product Status):

151031VS04000 (Würth Elektronik): Acceptable for applications where diffused lens transparency is permissible. Diffused construction may provide different light distribution characteristics than the original clear lens.
LTL-4236N (Lite-On Inc.): Available with extensive inventory (47,349 units). Forward voltage and package compatibility confirmed. Current rating of 10mA differs from the primary 20mA specification; verify circuit design compatibility.

Deprecated Status (Not Recommended for New Designs):

SLR-343MC3F (Rohm Semiconductor): Marked "Not For New Designs." Current rating of 10mA and significantly reduced brightness rating (25mcd) indicate limitations compared to original specification.
SLR-343PC3F (Rohm Semiconductor): Last Time Buy status with critical brightness limitation (6.3mcd). Not suitable for equivalent performance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3SUGC-F with 151031VS04000 in existing designs? A: Yes, with the caveat that 151031VS04000 features a diffused lens versus the clear lens of the original. This changes light distribution characteristics. Confirm optical requirements are met before deployment.

Q: What is the difference between clear and diffused lens transparency? A: Clear lenses provide directional light output with narrow viewing angle. Diffused lenses scatter light across a wider viewing angle. The 151031VS04000 provides 40° viewing angle versus the original 20°, resulting in broader light distribution.

Q: Why do some substitutes have 10mA test current while the original specifies 20mA? A: LTL-4236N, SLR-343MC3F, and SLR-343PC3F specify lower test currents. Verify circuit current-limiting design operates correctly with these components; they may exhibit different voltage-current characteristics.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed alternatives maintain ROHS3 Compliant status, meeting environmental and regulatory requirements identical to the primary component.

Q: What is the difference between Active and Not For New Designs product status? A: Active products are in production and recommended for new designs. Components marked "Not For New Designs" are retained for legacy support only. Active status components (HLMP-Y801-JPP00, LTL1CHKGKNN, LTL-4236N) are recommended for new circuit designs.

Q: Can I use LTL1CHKGKNN as a direct replacement in terms of physical fit? A: Yes. LTL1CHKGKNN shares identical T-1 package form factor with maximum height of 5.20mm, matching the original 5.30mm specification. Physical compatibility is confirmed for through-hole mounting.

Q: Which substitute provides the closest brightness match to the original 3SUGC-F? A: LTL1CHKGKNN provides the nearest brightness performance at 320mcd versus the original 300mcd specification. HLMP-Y801-JPP00 is also closely matched at 310mcd.
