Equivalent & Substitute Parts Reference – PXT2222A-TP

Part Overview

The PXT2222A-TP is a surface-mount NPN bipolar junction transistor (BJT) manufactured by Micro Commercial Co, classified under the Transistors, Bipolar (BJT) category. It features a collector current max of 600 mA, a collector-emitter breakdown voltage of 40 V, and a transition frequency of 300 MHz, in a SOT-89 (TO-243AA) package. With an active product status and inventory available, alternative models may be required for second sourcing, compliance with supply chain mandates, or package variation preferences. All substitutions must accurately match the electrical and mechanical parameters specified for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for BJT transistors in this category is strictly based on matching the following key parameters: Transistor Type (NPN), maximum collector current (Ic), maximum collector-emitter breakdown voltage (Vce), Vce saturation characteristics, cutoff current, minimum DC current gain (hFE), transition frequency, operating temperature range, mounting type, and package specifications. Only parts meeting the criteria as provided can be considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Only parts with an active status and matching compliance certifications should be selected for substitution. PXT2222A-TP is listed as Active. The substitute, CXT2222A TR PBFREE, is also Active and ROHS3 Compliant, with REACH status unaffected. Substitute selection may consider compliance status for regulatory or supply chain requirements.

Frequently Asked Questions (FAQ)

Q: What key parameters must match for a direct BJT transistor substitute?
A: Transistor Type, collector-emitter breakdown voltage, collector current, DC current gain, cutoff current, transition frequency, mounting type, package / case, and operating temperature range are required for direct substitution.

Q: Are both PXT2222A-TP and CXT2222A TR PBFREE compatible in terms of package and mounting?
A: Yes, both use TO-243AA package (SOT-89), and both are surface mount devices, ensuring mechanical compatibility.

Q: Does compliance status affect substitute selection?
A: Both parts are listed with unaffected REACH status. CXT2222A TR PBFREE indicates ROHS3 compliance, which may be required for regulatory purposes.

Q: Is the transition frequency relevant for signal applications substitution?
A: Both parts share a 300MHz transition frequency, ensuring equivalent performance in high-frequency circuit applications.

Q: Can operating temperature range impact substitution decisions?
A: Both models cover similar high-temperature ranges, with substitutable overlap.

Q: Is inventory level relevant in engineering selection?
A: Inventory information is provided but does not alter parameter-based suitability for substitution.

Q: Which mounting type do these models support?
A: Both PXT2222A-TP and CXT2222A TR PBFREE are designed for surface mount applications.
