Key Parameters

Substitute Part Grouping Explanation

Substitution for US6X3TR in the Transistors, Bipolar (BJT) category is determined strictly by matching or exceeding the following electrical and mechanical parameters: transistor type, collector-emitter breakdown voltage, collector current, saturation voltage, cutoff current, current gain, power rating, transition frequency, maximum operating temperature, mounting type, package style, RoHS and REACH compliance, moisture sensitivity level, and export classification. Substitutes listed strictly meet all these parameters within the required ranges and device formats, as provided.

Parameter Comparison

Engineering Selection Recommendations

US6X3TR is obsolete, and continued stocking or use in new designs is not supported for long-term production. PBSS4240Y,115 from Nexperia USA Inc. is active and meets RoHS3, REACH compliance, with identical ECCN and HTSUS classifications. Both devices are surface mount and qualify for unlimited moisture sensitivity level. Select substitute parts that match required certifications and regulatory statuses to ensure ongoing compliance in regulated applications.

Frequently Asked Questions (FAQ)

Q: What primary parameters determine the suitability of PBSS4240Y,115 as a substitute for US6X3TR?
A: Suitability is determined by NPN transistor type, voltage and current ratings, current gain, cutoff current, saturation voltage, frequency, power dissipation, maximum junction temperature, surface mount package, and compliance statuses.

Q: Are there differences in package format between US6X3TR and substitute PBSS4240Y,115?
A: US6X3TR uses a TUMT6 package, while PBSS4240Y,115 uses a 6-TSSOP, SC-88, SOT-363 package. Verify compatibility with existing PCB layouts.

Q: Do substitute transistors meet the same environmental and compliance regulations?
A: Both US6X3TR and PBSS4240Y,115 are RoHS3 compliant, REACH unaffected, MSL 1 (Unlimited), classified EAR99 for export, and share the same HTSUS code.

Q: Is there a difference in product status between US6X3TR and PBSS4240Y,115?
A: US6X3TR is obsolete; PBSS4240Y,115 is active and recommended for ongoing procurement and production continuity within provided parameters.

Q: Which electrical ratings need to be checked for functional compatibility when substituting?
A: Collector-emitter voltage, collector current, current gain, saturation voltage, cutoff current, and power rating must be checked for compatibility with circuit requirements.
