SM1206UOC-IL Orange LED 1206 SMD Equivalent and Substitute Parts

Part Overview

The SM1206UOC-IL is an orange 625nm LED indicator in 1206 (3216 Metric) surface mount package manufactured by Bivar Inc. This component is designated as obsolete, necessitating identification of compatible substitute parts for ongoing designs and manufacturing operations. The part specifications include a forward voltage of 2.1V at 20mA test current, 330mcd brightness rating, and 30° viewing angle with clear round lens design. Alternative components must maintain electrical compatibility within the 1206 package form factor while accommodating minor variations in optical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SM1206UOC-IL is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 1206 (3216 Metric) surface mount
• Mounting Type: Surface Mount
• Current - Test: 20mA operational specification
• Forward Voltage (Vf): 2.0V to 2.1V range
• Moisture Sensitivity Level: 3 or 4 (acceptable for equivalent environmental conditions)

Secondary Selection Factors:

• Wavelength - Dominant: 625nm orange (acceptable range: 590nm to 630nm for alternative colors)
• Millicandela Rating: 6mcd to 347mcd (application-dependent brightness selection)
• Viewing Angle: 30° to 140° (design-dependent field of view requirements)
• Lens Style: Round or Rectangle with Flat Top (mechanical fit consideration)
• Size / Dimension: 3.20mm L x 1.50mm to 1.60mm W (PCB footprint compatibility)
• Height (Max): 0.75mm to 1.40mm (clearance-dependent selection)

The identified substitute parts meet these criteria within the 1206 package family and maintain surface mount compatibility. Color variations (amber, yellow) represent functional equivalents where the application does not require specific orange wavelength specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Electrical Characteristics): SM1206AC-IL (Bivar Inc.) provides the closest match with identical package specifications, MSL rating, and mounting configuration. The amber wavelength (607nm) operates at slightly lower forward voltage (2V vs 2.1V) with comparable brightness (15mcd) and viewing angle (30°). This part maintains equivalent form factor and environmental handling requirements, making it suitable for direct PCB footprint substitution.

Active Product Alternatives with Brightness Considerations: Parts XZM2ACY55W-1 (347mcd) and XZMYK55W-1 (148mcd) from SunLED offer significantly enhanced brightness ratings while maintaining 2V forward voltage compatibility. These yellow (590nm) LED indicators feature reduced height (0.75mm maximum) and improved MSL rating (3 vs 4), with RoHS3 and REACH compliance certifications. The increased brightness range accommodates applications requiring higher optical output without electrical redesign.

Secondary Alternatives: EAST3215YA4-AM (Everlight Electronics Co Ltd) delivers 268mcd brightness with 2.05V forward voltage and improved MSL rating (3). QTLP650C3TR (onsemi, obsolete status) and 15-21VYC (Everlight Electronics Co Ltd, active) represent lower brightness options (10mcd and 6mcd respectively) with expanded viewing angles (140°) suitable for wide-angle indication applications.

RoHS and Compliance Status: XZM2ACY55W-1 and XZMYK55W-1 provide verified ROHS3 compliance and REACH Unaffected status. EAST3215YA4-AM includes ROHS3 Compliant designation. SM1206AC-IL specifies ROHS3 Compliant status. All substitute parts maintain equivalent environmental regulatory compliance for commercial and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can SM1206AC-IL directly replace SM1206UOC-IL on existing PCBs? A: Yes. SM1206AC-IL maintains identical 1206 (3216 Metric) package dimensions (3.20mm L x 1.60mm W, 1.40mm height maximum), surface mount configuration, and MSL rating (4). The amber wavelength (607nm) operates within compatible forward voltage range (2V vs 2.1V). Verify application tolerance for color change from orange to amber.

Q: What is the primary reason for considering substitute parts? A: SM1206UOC-IL holds obsolete product status. Active alternatives ensure continuous supply availability for manufacturing operations and future production batches.

Q: How do viewing angle differences affect substitution compatibility? A: Viewing angle (30° to 140° range across alternatives) determines field of view and brightness perception angle. Applications requiring narrow-beam indication (30°) should prioritize SM1206AC-IL. Wide-angle indication (130° to 140°) suits general status applications with reduced directional viewing constraints. Design documentation specifies required viewing angle.

Q: What is the significance of MSL ratings across substitute parts? A: MSL (Moisture Sensitivity Level) indicates soldering process handling requirements. SM1206UOC-IL (MSL 4, 72 hours) requires controlled humidity storage below 60% RH. Active alternatives XZM2ACY55W-1 and XZMYK55W-1 provide improved MSL 3 (168 hours) ratings, reducing moisture-related failure risk during manufacturing operations.

Q: Which substitute parts offer superior brightness characteristics? A: XZM2ACY55W-1 (347mcd) and EAST3215YA4-AM (268mcd) exceed original specification (330mcd). XZMYK55W-1 (148mcd) provides mid-range brightness. Lower brightness options (15-21VYC at 6mcd, QTLP650C3TR at 10mcd, SM1206AC-IL at 15mcd) suit applications tolerating reduced optical output.

Q: Are height differences between substitute parts a design consideration? A: Yes. XZM2ACY55W-1 and XZMYK55W-1 feature reduced maximum height (0.75mm vs 1.40mm original specification), providing clearance advantages in compact assemblies. Other alternatives maintain heights between 1.10mm and 1.40mm. Verify PCB assembly clearance requirements before substitution.

Q: Do all substitute parts comply with RoHS and environmental standards? A: XZM2ACY55W-1, XZMYK55W-1, and EAST3215YA4-AM specify ROHS3 Compliant status. SM1206AC-IL includes ROHS3 Compliant designation. QTLP650C3TR lists REACH Unaffected status without explicit RoHS certification. Verify compliance requirements for your specific application jurisdiction.

Q: What electrical parameters remain constant across all substitute options? A: All identified substitute parts maintain 20mA test current specification and operate within 2V to 2.1V forward voltage range. All utilize 1206 package with surface mount configuration, clear lens transparency, and flat top lens style. Forward voltage variation (2V to 2.1V) requires no circuit redesign for standard current-limiting resistor applications.
