Equivalent & Substitute Parts Reference for IMD1AT108

Part Overview

IMD1AT108 (Rohm Semiconductor) is a surface mount, dual pre-biased bipolar transistor comprising 1 NPN and 1 PNP element. It features a maximum collector-emitter breakdown voltage of 50V, supports up to 100mA collector current, includes base bias resistors, and is supplied in the SC-74, SOT-457 SMT6 package. The part status is “Not For New Designs,” indicating that engineers must identify suitable direct substitutes where sustained production, long-term support, or active status is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute qualification within the Transistors, Bipolar (BJT) category is strictly based on matching the following parameters: transistor type (dual pre-biased: 1 NPN + 1 PNP), collector-emitter voltage rating, maximum collector current, mounting type, package, and compliance certifications (RoHS, REACH, MSL). Only those alternative models explicitly listed and matching these criteria are considered valid electrical and mechanical substitutes.

Parameter Comparison

Engineering Selection Recommendations

IMD1AT108 is classified as “Not For New Designs.” Selection of substitute parts for ongoing or new projects should be limited to alternate models with an “Active” status and equivalent compliance: RoHS3, REACH, and MSL 1 ratings. PIMC31,115 (Nexperia USA Inc.) meets these compliance and inventory requirements, and its active product status supports continued design and manufacturing use.

Frequently Asked Questions (FAQ)

Q: What primary specifications determine substitute suitability for IMD1AT108?
A: Substitute parts must match transistor type (dual pre-biased: 1 NPN + 1 PNP), voltage rating (50V), mounting type (surface mount), package (SC-74, SOT-457), and compliance certifications (RoHS3, REACH, MSL 1).

Q: Does the substitute part PIMC31,115 have the same package dimensions as IMD1AT108?
A: Both IMD1AT108 and PIMC31,115 are supplied in the SC-74, SOT-457 surface mount package.

Q: Do differences in base resistor values or DC current gain affect substitution?
A: Substitution is strictly based on the provided allowed parameters. Any variation in internal bias resistor or gain must be confirmed as compatible within the user's circuit based on explicit value requirements.

Q: What compliance certifications do the main and substitute parts share?
A: Both models are ROHS3 Compliant, REACH Unaffected, and have Moisture Sensitivity Level (MSL) 1 (Unlimited).

Q: Is new production recommended with IMD1AT108?
A: IMD1AT108 is classified as “Not For New Designs”; use of alternate active models such as PIMC31,115 should be considered for ongoing product development.
