Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DTA123JUBTL is strictly governed by matching the following key parameters: transistor type (PNP - Pre-Biased), maximum collector current (100 mA), collector-emitter breakdown voltage (50 V), base resistor (2.2 kOhms), emitter-base resistor (47 kOhms), maximum power dissipation (200 mW), package type supporting surface mount capabilities, RoHS compliance, and MSL rating. Only parts meeting all these criteria are considered equivalent substitutes in this product category.

Parameter Comparison

Engineering Selection Recommendations

DTA123JUBTL has the product status "Not For New Designs" and is RoHS3 compliant with unlimited moisture sensitivity level. PDTA123JU,115 is active, RoHS3 compliant, possesses the same transistor type, electrical characteristics, mounting type, and MSL classification, and is not restricted for new design use. Both devices carry full REACH compliance. Only package outline differs; users must verify form factor compatibility during device selection while electrical and compliance parameters are aligned.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when substituting DTA123JUBTL with PDTA123JU,115?
A1: Substitution is governed by matching transistor type, collector current, breakdown voltage, base and emitter resistors, maximum power, mounting type, RoHS compliance, and MSL level.

Q2: Can PDTA123JU,115 be used in surface mount designs previously using DTA123JUBTL?
A2: PDTA123JU,115 supports surface mount applications but uses SC-70, SOT-323 package as opposed to SC-85, UMT3F. Form factor compatibility must be verified.

Q3: Is there a difference in RoHS and REACH status between the two equivalents?
A3: Both DTA123JUBTL and PDTA123JU,115 are ROHS3 compliant and REACH unaffected.

Q4: Are maximum ratings for collector current and power dissipation identical?
A4: Both devices are rated at 100 mA maximum collector current and 200 mW maximum power dissipation.

Q5: What should be considered regarding base and emitter resistors for substitute compatibility?
A5: Both parts feature 2.2 kOhms base resistor (R1) and 47 kOhms emitter-base resistor (R2), satisfying matching requirements for direct substitution.

Q6: How is moisture sensitivity addressed for these substitute transistors?
A6: Both parts are classified as MSL 1 (Unlimited), supporting unrestricted standard reflow soldering processes.

Q7: Which package types are supported by each part and are they directly interchangeable?
A7: DTA123JUBTL is in SC-85/UMT3F while PDTA123JU,115 is in SC-70, SOT-323. Mechanical footprint must be reviewed for direct interchangeability; electrical substitution is permitted per provided parameters.
