EMZ1-TP Equivalent & Substitute Parts

Part Overview

The EMZ1-TP is an active Bipolar (BJT) Transistor Array manufactured by Micro Commercial Co, featuring 1 NPN and 1 PNP configuration in a Surface Mount SOT-563 package. This component is designed for interface applications requiring dual-transistor functionality with 50V collector-emitter breakdown voltage and 150mA maximum collector current. The part operates across an extended temperature range of -55°C to 150°C and delivers 150mW maximum power dissipation with transition frequencies of 180MHz (NPN) and 140MHz (PNP).

Equivalent and substitute parts are identified to provide design flexibility for procurement, inventory management, and supply chain continuity. Substitute parts maintain electrical compatibility within specified parameter tolerances while potentially offering different packaging formats or supplier availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EMZ1-TP are classified based on electrical parameter compatibility and mechanical interchangeability. The substitution logic is strictly defined by the following critical parameters:

Primary Compatibility Criteria:

• Transistor configuration: NPN/PNP dual-transistor array
• Maximum collector current: 150mA minimum
• Collector-emitter breakdown voltage: 50V minimum
• Maximum power dissipation: 150mW minimum
• DC current gain (hFE): 120 minimum at specified conditions
• Collector cutoff current: 100nA maximum
• Operating temperature range: Support for -55°C to 150°C or subset thereof
• Surface Mount packaging with SOT-563 or SOT-666 compatibility

Substitute Classification:

Direct Equivalent (EMZ1T2R): Maintains all electrical parameters identical to the main part, including transition frequencies (180MHz, 140MHz), saturation voltage specifications, and power rating. Differs only in packaging format (EMT6 supplier package) and supplier (Rohm Semiconductor). Includes RoHS3 compliance and MSL Level 1 certification.

Similar Substitute (HN1B04FE-Y,LF): Meets core electrical requirements for collector current, breakdown voltage, and DC current gain. Differs in transition frequency (80MHz versus 180MHz/140MHz), power dissipation (100mW versus 150mW), and saturation voltage specifications. Supplied by Toshiba Semiconductor in ES6 package format with Tape & Reel packaging. Includes RoHS3 compliance and MSL Level 1 certification.

Parameter Comparison

Engineering Selection Recommendations

EMZ1T2R Selection Criteria:

The EMZ1T2R from Rohm Semiconductor is a direct electrical equivalent to the EMZ1-TP. This substitute maintains identical specifications for collector current (150mA), breakdown voltage (50V), DC current gain (120 @ 1mA, 6V), and transition frequencies (180MHz, 140MHz). The part is Active status with ROHS3 compliance and MSL Level 1 certification, indicating suitability for standard manufacturing environments without moisture sensitivity constraints. Selection of EMZ1T2R is appropriate when Rohm Semiconductor supply chain availability is preferred or when EMT6 packaging format is compatible with assembly processes. The higher inventory availability (133,300 pieces) supports extended production runs.

HN1B04FE-Y,LF Selection Criteria:

The HN1B04FE-Y,LF from Toshiba Semiconductor is a similar substitute with reduced performance specifications. This part maintains compatibility for collector current (150mA), breakdown voltage (50V), and DC current gain (120 @ 2mA, 6V). However, the transition frequency is reduced to 80MHz (versus 180MHz/140MHz), and maximum power dissipation is limited to 100mW (versus 150mW). Selection of HN1B04FE-Y,LF is appropriate for applications where lower frequency operation is acceptable and power dissipation requirements do not exceed 100mW. The part is Active status with ROHS3 compliance and MSL Level 1 certification. Toshiba supply availability (963 pieces) is lower than alternative sources.

Compliance and Regulatory Considerations:

All three parts maintain REACH Unaffected status and EAR99 ECCN classification. EMZ1T2R and HN1B04FE-Y,LF both carry ROHS3 compliance certification, supporting regulatory requirements for restricted substance elimination. MSL Level 1 rating for substitute parts indicates unlimited shelf life without moisture bake requirements.

Frequently Asked Questions (FAQ)

Q: Can EMZ1T2R be used as a direct replacement for EMZ1-TP in all applications?

A: EMZ1T2R maintains identical electrical specifications including collector current (150mA), breakdown voltage (50V), DC current gain (120 @ 1mA, 6V), and transition frequencies (180MHz, 140MHz). The parts are electrically interchangeable. Physical package compatibility depends on PCB layout design for SOT-563 or SOT-666 footprints. Supplier device packages differ (SOT-563 versus EMT6), but both support the same case outlines.

Q: What are the limitations of HN1B04FE-Y,LF as a substitute?

A: HN1B04FE-Y,LF operates at reduced transition frequency (80MHz versus 180MHz/140MHz) and lower maximum power dissipation (100mW versus 150mW). Applications requiring high-frequency switching or power dissipation above 100mW are not suitable for this substitute. Saturation voltage specifications also differ (250mV @ 10mA, 100mA versus 400mV @ 5mA, 50mA). Circuit designs must accommodate these parameter differences.

Q: Are there temperature range differences between the main part and substitutes?

A: EMZ1-TP specifies operating temperature from -55°C to 150°C. EMZ1T2R and HN1B04FE-Y,LF specify 150°C maximum without lower temperature limit documentation. Applications requiring operation below 0°C should confirm substitute part specifications with manufacturer datasheets.

Q: What packaging format differences exist between these parts?

A: EMZ1-TP uses SOT-563 supplier package. EMZ1T2R uses EMT6 supplier package. HN1B04FE-Y,LF uses ES6 supplier package. All three parts support SOT-563 and SOT-666 case outlines for PCB footprint compatibility. Packaging format differences affect tape reel specifications and assembly handling but not electrical performance or mechanical fit.

Q: Which substitute offers the best inventory availability?

A: EMZ1T2R from Rohm Semiconductor provides the highest inventory availability at 133,300 pieces. EMZ1-TP has 1,105 pieces available. HN1B04FE-Y,LF has 963 pieces available. Inventory levels support different production volume requirements.

Q: Do all parts meet RoHS compliance requirements?

A: EMZ1T2R and HN1B04FE-Y,LF both carry ROHS3 Compliant certification. EMZ1-TP RoHS status is not specified in available documentation. All three parts maintain REACH Unaffected status and EAR99 ECCN classification.

Q: What is the significance of MSL Level 1 rating on substitute parts?

A: MSL Level 1 (Unlimited) indicates that substitute parts have unlimited shelf life without moisture sensitivity constraints. No moisture bake procedures are required before assembly. This simplifies inventory management and reduces manufacturing process complexity compared to higher MSL ratings.
