The substitute part 2SC5488A-TL-H meets these criteria through equivalent voltage and current ratings, identical NPN polarity, surface mount construction, and matching regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 2SC5488A-TL-H serves as a direct functional substitute for the obsolete 2SC5231C8-TL-E based on the following factors:

Product Status: The 2SC5488A-TL-H maintains active production status with onsemi, ensuring long-term availability and supply chain continuity compared to the obsolete 2SC5231C8-TL-E.

Electrical Equivalence: Both devices share identical maximum voltage ratings (10V Vce) and maximum collector current specifications (70mA), establishing electrical compatibility for existing circuit designs.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 export classification, with identical moisture sensitivity levels (MSL 1), ensuring compliance requirements are preserved.

Manufacturing Continuity: Selection of the 2SC5488A-TL-H eliminates obsolescence risk while maintaining electrical and mechanical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 2SC5488A-TL-H directly replace the 2SC5231C8-TL-E without circuit modification?

A: The 2SC5488A-TL-H provides electrical equivalence in voltage and current ratings. However, package differences exist: the 2SC5231C8-TL-E uses SC-75/SOT-416 (SMCP), while the 2SC5488A-TL-H uses SC-81 (3-SSFP). PCB layout and footprint modifications are required.

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

A: The primary differences are product status (obsolete versus active), package configuration (SMCP versus 3-SSFP), and additional RF specifications on the 2SC5488A-TL-H (7GHz transition frequency, 1dB noise figure, 12dB gain). Electrical ratings for voltage and current are identical.

Q: Is the 2SC5488A-TL-H suitable for RF applications?

A: The 2SC5488A-TL-H includes RF specifications (7GHz transition frequency, noise figure, and gain parameters) indicating suitability for RF circuit applications. The 2SC5231C8-TL-E specifications do not include these RF parameters.

Q: Are there moisture sensitivity or storage concerns with either part?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: What compliance certifications apply to both parts?

A: Both the 2SC5231C8-TL-E and 2SC5488A-TL-H maintain REACH Unaffected status and EAR99 export classification, ensuring regulatory compliance for commercial and industrial applications.
