Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined based on identical transistor type, collector current (Ic), breakdown voltage (Vce), cutoff current, package/case, and mounting type. Regulatory compliance (RoHS3, REACH), moisture sensitivity level, and operational temperature are strictly matched. Variations in current gain (hFE), transition frequency, and maximum power are included only as specified in the input. All substitutes are surface mount NPN transistors with TO-243AA package and match the key electrical and mechanical characteristics allowed for substitution.

Parameter Comparison

Engineering Selection Recommendations

The primary driver for substitution is the product status of 2SD2211T100Q, which is "Not For New Designs." Both substitute parts, 2SC3649S-TD-E and 2SC3649T-TD-E, are classified as "Active." All parts are ROHS3 Compliant, REACH Unaffected, and have a moisture sensitivity level of 1 (Unlimited). Selection should prioritize active status and compliance for uninterrupted manufacturing and supply chain assurance as permitted by the provided data.

Frequently Asked Questions (FAQ)

Q: What are the main electrical criteria for substituting 2SD2211T100Q?
Substitute selection is based on identical transistor type (NPN), maximum collector current (1.5 A), maximum collector-emitter breakdown voltage (160 V), cutoff current, and surface mount TO-243AA package.

Q: Are the substitute parts compatible with the original mounting and footprint requirements?
All identified substitutes use the TO-243AA surface mount package, matching the mechanical requirements for direct replacement.

Q: How do environmental and regulatory certifications compare?
2SD2211T100Q and substitute parts 2SC3649S-TD-E and 2SC3649T-TD-E are ROHS3 Compliant, REACH Unaffected, and have a moisture sensitivity level of 1 (Unlimited).

Q: Why is it necessary to select substitute parts for this transistor?
2SD2211T100Q is marked as "Not For New Designs." Substitutes with "Active" status should be used for new and ongoing designs to ensure supply continuity.

Q: Are there differences in electrical characteristics between the main part and substitutes?
Substitutes present lower Vce saturation voltage, lower current gain, higher transition frequency, and lower maximum power dissipation compared to the original part. All other allowed substitution parameters conform to the input.
