EMD22T2R Equivalent & Substitute Parts Reference

Part Overview

The EMD22T2R from Rohm Semiconductor is a Pre-Biased Bipolar Transistor (BJT) featuring 1 NPN and 1 PNP transistor in a dual configuration. It is designed for surface mount applications and has key specifications such as a maximum collector current of 100mA, 50V breakdown voltage, and pre-set base and emitter resistors. This part is categorized under Transistors, Bipolar (BJT) and is supplied in EMT6/SOT-563/SOT-666 packaging. The device remains in active production status. Identifying electrical and mechanical equivalents is critical to ensure design flexibility, sourcing continuity, and risk mitigation for engineers in case of allocation, obsolescence, or supplier preference.

Key Parameters

Substitute Part Grouping Explanation

Substitution in the Transistors, Bipolar (BJT) category is determined strictly by parameters that affect electrical and mechanical compatibility. For EMD22T2R and listed substitutes, these parameters are: Transistor Type (1 NPN, 1 PNP pre-biased dual), maximum collector current, collector-emitter breakdown voltage, base and emitter resistor values, minimum DC current gain under specified conditions, collector cutoff current, maximum Vce saturation, power dissipation, package/case type, mounting style, supplier device package, RoHS status, MSL, and REACH status. Only parts matching all these essential criteria are eligible substitutes.

Parameter Comparison

Engineering Selection Recommendations

For ongoing production and new designs, select parts with "Active" product status, ROHS3 compliance, and MSL 1 (Unlimited) to fulfill long-term availability and regulatory requirements. EMD22T2R and NSBC143ZPDXV6T1G have active product status. PEMD13,115 is indicated as not for new designs. All compared parts meet ROHS3 and REACH requirements and have suitable moisture sensitivity levels for standard surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q1: What determines whether a bipolar transistor like EMD22T2R can be substituted?
A1: Substitution is determined by matching transistor configuration (1 NPN, 1 PNP pre-biased dual), current and voltage ratings, base and emitter resistor values, DC current gain, collector cutoff current, power dissipation, and mechanical package compatibility.

Q2: Are the package types for all listed substitutes identical?
A2: All parts are available in surface-mount packages SOT-563 and SOT-666, with minor differences in supplier device package nomenclature.

Q3: Can I use PEMD13,115 as a direct replacement in new designs?
A3: PEMD13,115 is listed as not for new designs. For new projects, select EMD22T2R or NSBC143ZPDXV6T1G with active status.

Q4: Do the substitutes have equivalent regulatory approvals and environmental compliance?
A4: All parts maintain ROHS3 compliance and REACH unaffected status, as well as MSL 1 (Unlimited), meeting typical regulatory and process requirements.

Q5: Does power dissipation or DC current gain differ significantly between the substitutes?
A5: Substitutes meet or exceed the minimum required parameters for EMD22T2R, with differences in power dissipation and DC current gain clearly indicated in the parameter comparison table. Select parts according to specific application needs within the listed values.
