Equivalent & Substitute Parts for 3SGC-F Green LED T-1 Through Hole

Part Overview

The 3SGC-F is an active green LED indication component manufactured by Bivar Inc., designed for through-hole mounting applications. This T-1 format discrete LED operates at 2.1V forward voltage with a 50mcd brightness rating and features a clear, domed lens for standard indication purposes. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to address inventory availability, extended lead times, or specific application requirements while maintaining functional compatibility within the green LED indication category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3SGC-F is determined by the following mandatory parameters:

Primary Compatibility Criteria:

• Color: Green (all substitutes must emit green light)
• Mounting Type: Through Hole (all substitutes must support PCB through-hole assembly)
• Lens Style: Round with Domed Top (mechanical compatibility with standard LED sockets)
• Lens Size: 3mm, T-1 format (physical envelope constraint)
• Package / Case: Radial (lead configuration for through-hole mounting)

Secondary Electrical Parameters:

• Voltage - Forward (Vf): 2.1V nominal (circuit design consideration; substitutes operate at 3.2V to 3.3V, requiring circuit verification)
• Current - Test: 20mA (standard test condition reference)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (all substitutes meet this requirement)
• Moisture Sensitivity Level: MSL 1 (all substitutes meet this requirement)

The three identified substitute parts meet the primary mechanical and compliance criteria. Electrical parameter variations (forward voltage and brightness) require circuit-level evaluation during implementation.

Parameter Comparison

Engineering Selection Recommendations

Mechanical Compatibility: All three substitute parts maintain T-1 / 3mm through-hole form factor compatibility with the 3SGC-F. Height variations (4.60mm to 5.55mm) fall within standard PCB assembly tolerances and do not preclude direct substitution in standard LED mounting applications.

Electrical Considerations: The 3SGC-F operates at 2.1V forward voltage. All substitute parts operate at higher forward voltages (3.2V to 3.3V). Circuit designs must accommodate this voltage differential through resistor value adjustment or verification that the application circuit supports the higher operating voltage range.

Brightness Differential: The 3SGC-F provides 50mcd brightness. Substitute parts deliver significantly higher brightness ratings (8400mcd to 15000mcd). Applications requiring specific brightness levels must evaluate whether increased luminous intensity affects visual performance or creates undesired glare.

Compliance Status: All parts maintain ROHS3 compliance and MSL 1 rating. All parts are active products with current manufacturer support. No compliance barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 3SGC-F be directly replaced with 151033GS03000 without circuit modification?

A: Direct mechanical substitution is possible due to identical T-1 / 3mm form factor and through-hole mounting compatibility. However, the forward voltage difference (2.1V vs. 3.2V) requires circuit evaluation. If the application circuit is designed for 2.1V operation, resistor values must be recalculated to maintain proper LED current at 3.2V forward voltage.

Q: What is the primary difference between the OVLBG4C7 and XLDG11W substitutes?

A: Both parts share identical T-1 form factor and through-hole mounting. Key differences include forward voltage (3.2V vs. 3.3V), brightness (8400mcd vs. 8990mcd), viewing angle (45° vs. 34°), and maximum height (5.35mm vs. 4.60mm). Selection depends on circuit voltage tolerance and desired optical distribution characteristics.

Q: Why does the 151033GS03000 have significantly higher brightness than the 3SGC-F?

A: The 151033GS03000 is rated at 15000mcd compared to the 3SGC-F at 50mcd. This brightness differential reflects different LED die specifications and optical design. Applications requiring lower brightness levels should evaluate whether the increased luminous intensity is compatible with the intended indication function.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts (151033GS03000, OVLBG4C7, XLDG11W) are ROHS3 compliant and maintain MSL 1 (unlimited) moisture sensitivity rating, matching the 3SGC-F compliance profile.

Q: Can the XLDG11W be used in applications with height constraints?

A: The XLDG11W has the lowest maximum height specification at 4.60mm, compared to 5.30mm for the 3SGC-F and 5.35mm to 5.55mm for other substitutes. Applications with strict height limitations should prioritize the XLDG11W for mechanical clearance compatibility.

Q: What viewing angle should be selected for my application?

A: The 3SGC-F provides a 20° viewing angle. Substitutes offer wider angles (30° to 45°). Wider viewing angles distribute light over a larger area, suitable for applications requiring visibility from multiple directions. Narrower angles concentrate light intensity in a specific direction. Selection depends on the intended indication visibility requirements.
