SM850K12TL Equivalent & Substitute Parts

Part Overview

The SM850K12TL is a monocrystalline solar cell from ANYSOLAR Ltd's IXOLAR™ series, rated at 221 mW maximum power output with an open circuit voltage of 8.29 V. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration. The SM850K12TL operates across a temperature range of -40°C to 90°C and is packaged as a bare cell with RoHS compliance and MSL Level 1 rating.

Due to its obsolete status, locating direct substitutes with identical electrical and mechanical specifications is essential for design continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SM850K12TL is based on electrical and mechanical parameter equivalence within the IXOLAR™ series. The primary substitute, SM850K12TF, maintains identical specifications across all critical performance parameters: open circuit voltage (8.29 V), maximum power point voltage (6.7 V), maximum power point current (32.9 mA), short circuit current (35.1 mA), cell type (monocrystalline), operating temperature range (-40°C to 90°C), and physical dimensions (38.50 × 33.00 × 1.50 mm).

The key substitution criteria are:

• Identical open circuit voltage (Voc)
• Identical maximum power point parameters (Vmpp, Impp)
• Identical short circuit current (Isc)
• Matching cell type and construction
• Matching thermal operating range
• Matching physical form factor and dimensions
• Equivalent compliance certifications (RoHS, MSL Level 1)

The SM850K12TF differs only in packaging format (tray versus cells) and product status (active versus obsolete), with maximum power output specified as 220.5 mW compared to 221 mW for the original part. This 0.5 mW variance falls within normal manufacturing tolerance for solar cell production.

Parameter Comparison

Engineering Selection Recommendations

The SM850K12TF is the direct active substitute for the obsolete SM850K12TL. Both components are manufactured by ANYSOLAR Ltd within the IXOLAR™ series and maintain electrical and mechanical equivalence across all specified parameters.

Selection of SM850K12TF is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• Identical electrical performance specifications (Voc, Vmpp, Impp, Isc)
• Matching thermal operating range (-40°C to 90°C)
• Identical physical dimensions enabling direct mechanical integration
• Equivalent compliance certifications (RoHS Compliant, MSL Level 1)
• Marginal power output variance (220.5 mW versus 221 mW) within manufacturing tolerance

The primary distinction is packaging format: SM850K12TF is supplied in tray packaging rather than as loose cells. This packaging difference does not affect electrical or mechanical compatibility in applications where individual cells are extracted and integrated into larger solar arrays or modules.

Frequently Asked Questions (FAQ)

Q: Can SM850K12TF directly replace SM850K12TL in existing designs?

A: Yes. The SM850K12TF maintains identical electrical specifications (8.29 V open circuit voltage, 6.7 V at maximum power point, 32.9 mA at maximum power point, 35.1 mA short circuit current) and physical dimensions (38.50 × 33.00 × 1.50 mm). Direct substitution is supported for all electrical and mechanical requirements.

Q: What is the significance of the packaging difference between the two parts?

A: SM850K12TL is specified as "Cells" packaging while SM850K12TF is supplied in "Tray" packaging. This difference affects handling and logistics but does not impact electrical performance or mechanical form factor. Individual cells can be extracted from tray packaging for integration into applications requiring loose cell components.

Q: Are there compliance differences between SM850K12TL and SM850K12TF?

A: Both parts maintain RoHS compliance and MSL Level 1 (Unlimited) rating. SM850K12TF includes additional regulatory documentation: REACH Unaffected status and HTSUS classification 8541.43.0080. These certifications do not alter functional equivalence.

Q: What is the power output variance between these parts?

A: SM850K12TL is rated at 221 mW maximum power while SM850K12TF is rated at 220.5 mW maximum power. This 0.5 mW difference (0.23% variance) is within normal manufacturing tolerance for monocrystalline solar cell production and does not constitute a functional limitation.

Q: Are both parts suitable for the full -40°C to 90°C operating temperature range?

A: Yes. Both SM850K12TL and SM850K12TF are specified for identical operating temperature ranges of -40°C to 90°C, ensuring thermal compatibility across all environmental conditions.

Q: Why is SM850K12TL classified as obsolete?

A: SM850K12TL has reached end-of-life status within ANYSOLAR Ltd's product portfolio. SM850K12TF represents the active equivalent within the IXOLAR™ series, ensuring continued availability for new designs and ongoing production requirements.
