Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC264030R is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Transistor configuration: 2 NPN - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Maximum collector-emitter breakdown voltage: 50V
• Internal base resistor value: 47kOhms
• Internal emitter-base resistor value: 47kOhms
• Maximum power dissipation: 300mW
• Moisture sensitivity level: 1 (Unlimited)

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package compatibility: SOT-23-6 or equivalent 6-pin surface mount packages

Substitute parts are classified into two categories:

Direct Equivalents: Parts with identical transistor configuration (2 NPN - Pre-Biased), matching internal resistor values, and equivalent electrical ratings.

Functional Equivalents: Parts with compatible electrical ratings and transistor configuration but differing in specific parameters such as internal resistor values, package variants, or additional features (such as automotive qualification), which remain functionally interchangeable within the specified parameter ranges.

Engineering Selection Recommendations

IMH3AT110 (Rohm Semiconductor): This part is an active product with ROHS3 compliance and REACH unaffected status. It maintains the dual NPN pre-biased configuration and equivalent electrical ratings (100mA collector current, 50V breakdown voltage, 300mW power dissipation). The internal base resistor differs at 4.7kOhms versus 47kOhms in the original part. This part is suitable for applications where the lower base resistor value is compatible with circuit design requirements. Inventory availability is high at 7750 pieces.

RN4604(TE85L,F) (Toshiba Semiconductor and Storage): This part is an active product with RoHS compliance. It features a mixed configuration of 1 NPN and 1 PNP transistor with internal 47kOhms base resistors matching the original part. Electrical ratings are equivalent (100mA collector current, 50V breakdown voltage, 300mW power dissipation). The mixed NPN/PNP configuration provides additional functionality for complementary switching applications. Inventory availability is 2680 pieces.

UMH2NFHATN (Rohm Semiconductor): This part is an active product with ROHS3 compliance, REACH unaffected status, and automotive qualification (AEC-Q101). It maintains the dual NPN pre-biased configuration with internal 47kOhms resistors matching the original part. Maximum power dissipation is 150mW, which is lower than the original 300mW specification. This part is suitable for applications where automotive-grade qualification is required and power dissipation does not exceed 150mW. Inventory availability is 1827 pieces.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level and are compliant with environmental regulations. Selection should be based on specific circuit requirements regarding internal resistor values, transistor configuration, power dissipation limits, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can IMH3AT110 replace DMC264030R directly in all applications?

A: IMH3AT110 maintains electrical compatibility in maximum ratings (100mA collector current, 50V breakdown voltage, 300mW power dissipation) and dual NPN pre-biased configuration. However, the internal base resistor is 4.7kOhms compared to 47kOhms in the original part. Circuit behavior will differ due to this resistor value change. Verification of circuit performance is necessary when the base resistor value affects biasing conditions.

Q: What is the key difference between RN4604(TE85L,F) and DMC264030R?

A: RN4604(TE85L,F) contains 1 NPN and 1 PNP transistor configuration, whereas DMC264030R contains 2 NPN transistors. Both maintain 47kOhms internal base resistors and equivalent electrical ratings. The mixed NPN/PNP configuration in RN4604(TE85L,F) enables complementary switching applications not possible with the dual NPN configuration.

Q: Is UMH2NFHATN suitable for high-power applications?

A: UMH2NFHATN has a maximum power dissipation rating of 150mW, which is lower than the original DMC264030R specification of 300mW. This part is suitable only for applications where power dissipation remains below 150mW. For applications requiring 300mW dissipation capability, IMH3AT110 or RN4604(TE85L,F) are appropriate selections.

Q: Are all substitute parts RoHS compliant?

A: Yes. DMC264030R is RoHS Compliant. IMH3AT110 and UMH2NFHATN are ROHS3 Compliant. RN4604(TE85L,F) is RoHS Compliant. All parts meet environmental compliance requirements.

Q: What is the package compatibility between substitute parts and the original DMC264030R?

A: DMC264030R uses SOT-23-6 package (Mini6-G4-B). IMH3AT110 uses SC-74 or SOT-457 package (SMT6). RN4604(TE85L,F) uses SC-74 or SOT-457 package (SM6). UMH2NFHATN uses 6-TSSOP, SC-88, or SOT-363 package (UMT6). Physical package dimensions differ. PCB layout modifications may be required for mechanical fit.

Q: Which substitute part has the highest inventory availability?

A: IMH3AT110 has the highest inventory availability at 7750 pieces in stock.

Q: Does UMH2NFHATN have automotive qualification?

A: Yes. UMH2NFHATN is qualified to AEC-Q101 automotive standard and carries automotive grade designation. This part is suitable for automotive applications requiring qualified components.

Q: What is the transition frequency specification for substitute parts?

A: IMH3AT110, RN4604(TE85L,F), and UMH2NFHATN all specify 250MHz transition frequency. The original DMC264030R does not provide transition frequency specification.
