Key Parameters

Substitute Part Grouping Explanation

Substitution of the PRT-07845 is determined by the following electrical and mechanical parameters:

• Cell Type: Monocrystalline construction
• Power Output Range: Minimum 450 mW to accommodate existing circuit power budgets
• Voltage Class: Open circuit voltage of 4.5 V or higher to maintain system voltage compatibility
• Current Characteristics: Short circuit current (Isc) sufficient to support load requirements
• Package Form: Cell-based packaging suitable for direct integration
• Compliance Status: RoHS and REACH certifications where applicable

The substitute part SLMD481H08L from ANYSOLAR Ltd meets these criteria with higher power output (714 mW) and voltage (5.04 V open circuit), providing enhanced performance within the monocrystalline solar cell category.

Parameter Comparison

Engineering Selection Recommendations

The SLMD481H08L represents a direct functional substitute for the PRT-07845 based on matching cell type (monocrystalline) and exceeding minimum electrical performance requirements. The substitute provides 58.7% higher power output and 12% higher open circuit voltage, supporting applications requiring enhanced energy generation within the same physical form factor category.

The SLMD481H08L carries ROHS3 compliance certification, whereas the PRT-07845 is RoHS non-compliant. This distinction is significant for applications subject to regulatory compliance requirements in electronics manufacturing and end-use markets.

Both components are classified as obsolete. Selection between these parts should be based on specific application voltage and power requirements, compliance obligations, and physical dimension constraints.

Frequently Asked Questions (FAQ)

Q: Can the SLMD481H08L directly replace the PRT-07845 in existing designs?

A: The SLMD481H08L is electrically compatible as a substitute. Both are monocrystalline solar cells with comparable voltage characteristics (4.5 V vs. 5.04 V open circuit). The substitute provides higher power output (714 mW vs. 450 mW) and current capacity (200 mA vs. 100 mA Isc). Physical dimensions must be verified against available mounting space, as the SLMD481H08L specifies 89.00mm x 55.00mm x 2.00mm.

Q: What are the key electrical differences between these parts?

A: The SLMD481H08L delivers 264 mW additional power output and 100 mA higher short circuit current compared to the PRT-07845. Open circuit voltage is 0.54 V higher. These differences indicate the substitute is rated for higher energy generation capacity within the same cell technology class.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance status is a regulatory and procurement consideration. The SLMD481H08L is ROHS3 compliant, while the PRT-07845 is non-compliant. Applications subject to RoHS requirements must use compliant components. For applications without such constraints, both parts are functionally substitutable based on electrical parameters.

Q: Are there physical mounting differences between these solar cells?

A: Both components use cell-based packaging. The SLMD481H08L provides specific dimensional data (89.00mm x 55.00mm x 2.00mm). The PRT-07845 dimensions are not specified in available documentation. Physical verification against mounting requirements is necessary before final selection.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. Availability is limited to existing inventory. For new designs, current-generation monocrystalline solar cells should be evaluated as long-term alternatives.
