2N2218A Equivalent & Substitute Parts Reference

Part Overview

The 2N2218A, manufactured by Microchip Technology, is an NPN Bipolar Junction Transistor (BJT) in the Transistors, Bipolar (BJT) category. This device features a 30 V collector-emitter breakdown voltage, 800 mA maximum collector current, 800 mW power dissipation, and is housed in a TO-39 (TO-205AD) through-hole metal can package. The 2N2218A part status is listed as Active.

Finding substitute parts for the 2N2218A may be required due to inventory availability, compliance requirements, or project demands. Substitution must strictly adhere to electrical, mechanical, and compliance parameters specified for this category and package.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2N2218A are identified by comparing only the explicitly provided parameters. Acceptable substitutes must match or exceed the main part in the following key properties:

• Transistor Type: NPN
• Maximum Collector Current (Ic)
• Maximum Collector-Emitter Breakdown Voltage (Vce)
• Vce Saturation (specified conditions)
• Collector Cutoff Current (ICBO/Ic(off))
• Minimum DC Current Gain (hFE) at specified conditions
• Maximum Power Dissipation
• Operating Temperature Range
• Package/Case and Mounting Type
• RoHS and REACH compliance status
• Product status as Active

Parts are considered substitutes only if they comply with these values as specified in the provided data.

Parameter Comparison

Engineering Selection Recommendations

Both 2N2218A and 2N2270 PBFREE are listed as Active products and are available in through-hole TO-39 metal can packages. The 2N2218A is noted as RoHS non-compliant, while the 2N2270 PBFREE is ROHS3 Compliant. Both parts are REACH Unaffected. Product selection may be based on project compliance requirements related to RoHS and availability status, as all other provided parameters are explicitly covered in the comparison table.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if a bipolar transistor is a substitute for 2N2218A?
Substitution is based only on provided electrical parameters (such as transistor type, voltage, current, power ratings, and gain), mechanical characteristics (package, mounting), compliance (RoHS, REACH statuses), and product status.

Q2: Are the package and mounting types equivalent between 2N2218A and 2N2270 PBFREE?
Yes. Both the 2N2218A and 2N2270 PBFREE use a TO-205AD, TO-39-3 Metal Can package and are designed for through-hole mounting.

Q3: How important is RoHS compliance in selecting a substitute?
RoHS status must match project or application requirements. The 2N2218A is RoHS non-compliant; the 2N2270 PBFREE is ROHS3 Compliant. Selection should be made based on project-specific compliance needs.

Q4: Is there a difference in maximum ratings between the 2N2218A and 2N2270 PBFREE?
All parameter differences are detailed in the Parameter Comparison table. Substitution is permitted strictly within the bounds of provided values. No further performance implications are addressed beyond what is provided.
