DTC124ESATP Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor DTC124ESATP is a pre-biased NPN bipolar junction transistor (BJT) with a maximum collector-emitter breakdown voltage of 50 V, maximum collector current of 30 mA, and through hole SPT mounting. The product is designated as obsolete, which necessitates the identification of alternative models for continued design support and inventory replenishment within the transistors, bipolar (BJT) category. Substitute parts are required to match the core electrical and mechanical parameters for direct replacement without design modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching these key parameters: transistor type (NPN - Pre-Biased), collector-emitter voltage rating (50 V), base and emitter-base resistor values (22 kOhms each), DC current gain, collector cutoff current, frequency response, and compliance designations. Mechanical compatibility (mounting type and package) is also a valid substitution factor. Substitute parts are grouped only when they align with these core electrical and mechanical attributes.

Parameter Comparison

Engineering Selection Recommendations

DTC124ESATP is categorized as obsolete while substitute DDTC124EUA-7-F is active. Both parts are ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level (MSL) 1 (Unlimited). Engineering selection based on status and compliance is appropriate, taking into account only the provided certifications and inventory availability.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting DTC124ESATP with other parts?
A1: Substitution relies on matching transistor type, collector-emitter voltage, resistor values, DC current gain, collector cutoff current, frequency response, compliance codes, and package specifications as provided.

Q2: Are there differences in mounting type and package for DTC124ESATP and DDTC124EUA-7-F?
A2: DTC124ESATP uses through hole mounting with SC-72 Formed Leads; DDTC124EUA-7-F uses surface mount packaging (SC-70, SOT-323).

Q3: Is compliance with RoHS and REACH relevant for substitution?
A3: Both DTC124ESATP and substitute DDTC124EUA-7-F are ROHS3 Compliant and REACH Unaffected, relevant for environmental and regulatory requirements.

Q4: Does collector current rating affect substitution?
A4: The main part has a maximum collector current of 30 mA; the substitute supports up to 100 mA. Substitution is valid only when the substitute part meets or exceeds the required specification.

Q5: Are substitute parts available in stock?
A5: According to provided parameters, inventory for DTC124ESATP is 8300 pieces; DDTC124EUA-7-F has 18100 pieces available.

Q6: Is there any difference in maximum power handling?
A6: DTC124ESATP specifies 300 mW; DDTC124EUA-7-F specifies 200 mW. Substitution requires consideration of application power requirements based on provided values.
