Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STW8C2SA/3030(GC) is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) within ±0.1V of 6.1V nominal
• Maximum current rating of 200mA or greater
• Test current of 100mA or greater

Mechanical Compatibility:

• Package / Case: 1212 (3030 Metric)
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• Color: White
• CRI: 80 or greater

Compliance Requirements:

• RoHS3 Compliant
• ECCN: EAR99

The substitute parts are grouped into two categories: direct parametric equivalents from Seoul Semiconductor Inc. (STW8C2SB series) and cross-manufacturer parametric equivalents from ams-OSRAM USA INC. (DURIS® S 5 series). All listed substitutes meet the electrical, mechanical, and compliance criteria for direct replacement in applications designed for the STW8C2SA/3030(GC).

Parameter Comparison

Engineering Selection Recommendations

Seoul Semiconductor Inc. STW8C2SB Series (Direct Equivalents)

The STW8C2SB, STW8C2SB-NZ, and STW8C2SB-NZ(DISTY) are direct parametric equivalents manufactured by Seoul Semiconductor Inc. All three variants maintain identical electrical specifications (6.1V Vf, 100mA test current, 200mA maximum) and mechanical compatibility with the obsolete STW8C2SA/3030(GC). These parts carry active product status and ROHS3 compliance. The primary distinction among these three variants is packaging designation and inventory availability. Selection among these three should be based on procurement channel and supply chain requirements.

ams-OSRAM USA INC. DURIS® S 5 Series (Cross-Manufacturer Equivalents)

The GW PSLR31.EM-LR-XX33-1-150-R18 and GW PSLR31.EM-LR-XX35-1-150-R18 are cross-manufacturer parametric equivalents from the DURIS® S 5 product line. These parts operate at 6.2V forward voltage (0.1V higher than the original) with a test current of 150mA. Both maintain 200mA maximum current rating, 120° viewing angle, 80 CRI, and 1212 (3030 Metric) package compatibility. The DURIS® S 5 series exhibits lower seated height (0.028" vs. 0.033") and higher thermal resistance (17°C/W vs. 10°C/W). These parts carry active product status, ROHS3 compliance, and MSL 3 moisture sensitivity rating. Selection of DURIS® S 5 variants should account for the thermal resistance difference and higher test current specification in thermal design calculations.

Frequently Asked Questions (FAQ)

Q: Can STW8C2SB series parts be used as direct drop-in replacements for STW8C2SA/3030(GC)?

A: Yes. The STW8C2SB, STW8C2SB-NZ, and STW8C2SB-NZ(DISTY) maintain identical electrical specifications (6.1V Vf, 100mA test current, 200mA maximum current) and mechanical compatibility (1212 3030 Metric package, 120° viewing angle, 80 CRI). These parts are parametric equivalents suitable for direct replacement in existing designs.

Q: What is the difference between STW8C2SB, STW8C2SB-NZ, and STW8C2SB-NZ(DISTY)?

A: All three variants are electrically and mechanically identical. The designations reflect different packaging and distribution channels. Selection should be based on procurement availability and supply chain requirements.

Q: Can DURIS® S 5 parts replace the STW8C2SA/3030(GC)?

A: DURIS® S 5 parts (GW PSLR31.EM-LR-XX33-1-150-R18 and GW PSLR31.EM-LR-XX35-1-150-R18) are parametric equivalents with compatible mechanical specifications but differ in electrical operation. Forward voltage is 6.2V (0.1V higher), test current is 150mA (50mA higher), thermal resistance is 17°C/W (higher than 10°C/W), and seated height is 0.028" (lower than 0.033"). These differences require thermal design review before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the compliance status of the original STW8C2SA/3030(GC).

Q: What is the significance of the height difference between substitute parts?

A: The STW8C2SA/3030(GC) has a maximum seated height of 0.033" (0.85mm). Seoul Semiconductor STW8C2SB variants are 0.031" (0.80mm), and ams-OSRAM DURIS® S 5 variants are 0.028" (0.70mm). Lower height variants provide additional clearance in space-constrained applications but require verification of solder joint formation and reflow profile compatibility.

Q: What thermal considerations apply when substituting with DURIS® S 5 parts?

A: DURIS® S 5 parts have thermal resistance of 17°C/W compared to 10°C/W for the original and Seoul Semiconductor equivalents. Higher thermal resistance results in greater junction temperature rise for equivalent power dissipation. Thermal design calculations should account for this difference, particularly in high-current or high-ambient-temperature applications.

Q: Are there inventory differences among the substitute parts?

A: Yes. Inventory levels vary: STW8C2SB (178,900 pcs), STW8C2SB-NZ (947 pcs), STW8C2SB-NZ(DISTY) (1,094 pcs), GW PSLR31.EM-LR-XX33-1-150-R18 (729 pcs), and GW PSLR31.EM-LR-XX35-1-150-R18 (717 pcs). Procurement decisions should consider both availability and lead time requirements.
