PRT-09241 Monocrystalline Solar Cell 5.2W 8V Equivalent & Substitute Parts

Part Overview

The PRT-09241 is a monocrystalline solar cell manufactured by SparkFun Electronics with a maximum power output of 5.2 W at 8 V open circuit voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system design and maintenance applications. The part is RoHS compliant and carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity during storage and handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for monocrystalline solar cells is determined by the following parameters:

• Cell Type: Both parts must be monocrystalline construction
• Voltage Compatibility: Open circuit voltage (Voc) must support the intended application voltage range
• Power Output: Maximum power rating must meet or exceed system requirements
• Current Characteristics: Short circuit current (Isc) and current at maximum power point (Impp) must be compatible with downstream circuitry
• Packaging: Cell format and mechanical dimensions must fit the application
• Compliance Requirements: RoHS status and regulatory certifications must align with end-use requirements

The PRT-13783 qualifies as a substitute based on matching cell type (monocrystalline), compatible voltage characteristics (7 V Voc vs. 8 V Voc), and higher power output (6 W vs. 5.2 W). However, RoHS compliance status differs between the two parts.

Parameter Comparison

Engineering Selection Recommendations

PRT-13783 as Primary Substitute: The PRT-13783 is an active product with higher power output (6 W vs. 5.2 W) and compatible monocrystalline construction. The open circuit voltage of 7 V is within acceptable tolerance for most applications designed for the 8 V PRT-09241. Current availability and active product status make this the preferred alternative for new designs and ongoing production.

RoHS Compliance Consideration: The PRT-09241 is RoHS compliant, while the PRT-13783 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this difference in material composition and environmental restrictions.

Voltage Differential: The 1 V difference in open circuit voltage (8 V vs. 7 V) is within typical solar cell manufacturing tolerances and does not preclude substitution in applications with appropriate voltage regulation or power conditioning circuits.

Frequently Asked Questions (FAQ)

Q: Can PRT-13783 directly replace PRT-09241 in existing designs?

A: Direct replacement is possible in applications where the 1 V lower open circuit voltage and higher power output do not conflict with system design parameters. Voltage regulation circuits and maximum power point tracking (MPPT) systems will accommodate this variation. RoHS compliance requirements must be evaluated independently.

Q: What is the significance of the power rating difference (5.2 W vs. 6 W)?

A: The PRT-13783 provides approximately 15% higher maximum power output. This represents improved performance and is generally compatible with systems designed for the lower-power PRT-09241, provided the downstream charging or power conditioning circuitry can handle the increased current.

Q: How do the current characteristics compare?

A: The PRT-09241 specifies 650 mA short circuit current (Isc). The PRT-13783 specifies 1.025 A at maximum power point (Impp) with 6 V. These measurements reflect different operating conditions and cannot be directly compared without additional electrical characterization data.

Q: Does packaging format affect substitution?

A: Both parts use Cells packaging format. The PRT-13783 is supplied in Bulk packaging, which may affect procurement, handling, and inventory management but does not impact electrical or mechanical compatibility.

Q: What is the impact of RoHS non-compliance for PRT-13783?

A: RoHS non-compliance indicates the presence of restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, or PBDEs) in the component. Applications subject to RoHS directives or customer specifications requiring RoHS compliance cannot use PRT-13783 as a substitute.
