IMD8AT108 Equivalent & Substitute Parts Reference

Part Overview

Rohm Semiconductor IMD8AT108 is a dual pre-biased bipolar transistor (BJT), integrating one NPN and one PNP transistor for surface mount applications. It supports a maximum collector current of 100mA and a maximum collector-emitter voltage of 50V. With a collector power dissipation of 300mW and a resistor base (R1) of 47kOhms, the device is housed in an SMT6 package (SC-74, SOT-457). The IMD8AT108 is listed as "Not For New Designs," prompting the need for compatible and compliant substitute models.

Key Parameters

Substitute Part Grouping Explanation

Only substitute parts matching key functional and compliance parameters are considered. The selection is strictly limited to: transistor configuration (1 NPN, 1 PNP - Pre-Biased, Dual), maximum voltage and current ratings, maximum power dissipation, base resistor value (R1), DC current gain, Vce saturation, mounting type, package compatibility, RoHS compliance, and moisture sensitivity. Substitutes listed below meet these criteria either explicitly or by matching all core electrical and mechanical parameters provided in the source.

Parameter Comparison

Engineering Selection Recommendations

IMD8AT108 is classified as "Not For New Designs." Both PIMC31,115 and PUMD14,115 are active and compliant alternatives, each with RoHS3 and REACH certification and an MSL of 1 (Unlimited). Selection should be based on matching electrical parameters, mechanical footprint, and compliance requirements as outlined in the provided data.

Frequently Asked Questions (FAQ)

Q: What parameters are critical for selecting substitutes for IMD8AT108?
A: Substitutes must match transistor configuration (1 NPN, 1 PNP - Pre-Biased), maximum collector-emitter voltage (50V), maximum collector current, maximum power dissipation, base resistor value (R1), DC current gain (hFE), Vce saturation, surface mount footprint, package compatibility, RoHS compliance, and MSL.

Q: Can PIMC31,115 be used as a direct substitute for IMD8AT108?
A: PIMC31,115 matches several key functional and mechanical parameters, with differing current and resistor base ratings. Device selection should align with the application's specific requirements.

Q: Is package compatibility assured between IMD8AT108 and PUMD14,115?
A: Package types differ (SC-74 for IMD8AT108, 6-TSSOP/SC-88/SOT-363 for PUMD14,115). Mechanical compatibility must be verified based on the application’s PCB layout and constraints.

Q: Are all substitute parts RoHS3 and REACH compliant?
A: Yes, all listed substitutes and the main part are RoHS3 and REACH compliant as indicated in the provided data.

Q: What is the significance of the "Not For New Designs" status?
A: This status indicates that IMD8AT108 is not recommended for new project designs and substitute models should be considered for ongoing and future requirements.

Q: Does Moisture Sensitivity Level (MSL) affect substitute choice?
A: All referenced parts have MSL 1 (Unlimited), which equates to no restrictions for standard surface mount assembly processes.
