2SC3583-T1B-A RF Transistor NPN Equivalent & Substitute Parts

Part Overview

The 2SC3583-T1B-A is an RF transistor NPN manufactured by CEL, designed for high-frequency applications up to 9GHz. This device operates at 10V collector-emitter breakdown voltage with a maximum power dissipation of 200mW in a surface mount SOT-23-3 package. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain functional compatibility within the RF frequency domain while accommodating application-specific electrical and thermal requirements.

Substitute Part Grouping Explanation

Substitution logic for the 2SC3583-T1B-A is based on the following critical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN (mandatory match)
• Voltage - Collector Emitter Breakdown (Max): ≥10V (equal or higher rating required)
• Frequency - Transition: ≥9GHz (equal or higher frequency capability required)
• Power - Max: ≥200mW (equal or higher power dissipation capability required)
• Current - Collector (Ic) (Max): ≥65mA (equal or higher current handling required)
• Mounting Type: Surface Mount (package form factor consideration)
• Operating Temperature: ≤150°C (thermal rating compatibility)

Substitute Parts Identified:

1. BFP420H6327XTSA1 (Infineon Technologies) – Lower voltage (5V) and lower power (160mW) rating; suitable for applications with reduced voltage and power requirements within the 25GHz frequency domain.

2. BFP460H6327XTSA1 (Infineon Technologies) – Lower voltage (5.8V) rating but higher frequency (22GHz) and higher power (230mW) capability; suitable for high-frequency applications with moderate voltage constraints.

3. BFR380L3E6327XTMA1 (Infineon Technologies) – Voltage rating of 9V (near-equivalent to 10V), higher frequency (14GHz), and significantly higher power (380mW); suitable for applications requiring enhanced power handling and frequency performance.

4. MAPR-000912-500S00 (MACOM Technology Solutions) – Significantly higher voltage (80V) and power (500W) rating with chassis mount packaging; suitable only for high-power RF applications with different thermal and mechanical requirements.

5. MRF448 (MACOM Technology Solutions) – Higher voltage (50V) and power (250W) rating with chassis mount packaging; suitable only for high-power RF applications with different thermal and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

For Surface Mount RF Applications (9GHz–25GHz Domain):

The Infineon Technologies BFP420H6327XTSA1, BFP460H6327XTSA1, and BFR380L3E6327XTMA1 are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). These devices maintain surface mount packaging suitable for PCB integration.

• BFP420H6327XTSA1 is applicable where voltage and power constraints are reduced (5V, 160mW) but frequency capability extends to 25GHz.
• BFP460H6327XTSA1 provides balanced performance with 5.8V rating, 22GHz frequency, and 230mW power in active production status.
• BFR380L3E6327XTMA1 offers the closest voltage approximation (9V) to the original 2SC3583-T1B-A with enhanced power (380mW) and frequency (14GHz) performance, packaged in SOT-883.

For High-Power RF Applications (Chassis Mount):

The MACOM Technology Solutions MAPR-000912-500S00 and MRF448 are active products with ROHS3 compliance but employ chassis mount packaging fundamentally different from the original SOT-23-3 form factor. These devices are suitable only for applications requiring significantly higher voltage and power ratings (80V/500W and 50V/250W respectively) with different thermal management strategies.

Compliance Considerations:

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the original part. All active substitutes are ROHS3 compliant, supporting environmental and regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q1: Can BFP420H6327XTSA1 directly replace 2SC3583-T1B-A in all applications?

No. BFP420H6327XTSA1 has a lower voltage rating (5V vs. 10V) and lower power rating (160mW vs. 200mW). It is suitable only for applications where the circuit operates at reduced voltage and power levels. The higher frequency capability (25GHz) does not compensate for reduced electrical ratings in voltage-sensitive designs.

Q2: Why are MAPR-000912-500S00 and MRF448 listed as substitutes if they use chassis mount packaging?

These parts are listed because they appear in the original substitute list provided for 2SC3583-T1B-A. However, they are not practical direct replacements due to fundamentally different mounting types (chassis mount vs. surface mount SOT-23-3). They serve applications requiring high-power RF amplification with different PCB integration strategies and thermal management approaches.

Q3: Which substitute offers the best electrical compatibility with 2SC3583-T1B-A?

BFR380L3E6327XTMA1 provides the closest electrical compatibility: 9V voltage rating (near 10V), 14GHz frequency (exceeds 9GHz requirement), 380mW power (exceeds 200mW requirement), and 80mA collector current (exceeds 65mA requirement). It maintains surface mount packaging (SOT-883) suitable for PCB integration, though package dimensions differ from SOT-23-3.

Q4: Are all substitute parts in active production?

Yes. All five substitute parts listed (BFP420H6327XTSA1, BFP460H6327XTSA1, BFR380L3E6327XTMA1, MAPR-000912-500S00, MRF448) have active product status, ensuring availability and long-term supply continuity. The original 2SC3583-T1B-A is obsolete.

Q5: What is the significance of MSL 1 (Unlimited) rating?

MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts maintain this rating, ensuring consistent handling procedures and storage conditions across substitution options.

Q6: Do substitute parts require circuit redesign?

Substitution feasibility depends on application-specific voltage, power, and frequency requirements. BFP420H6327XTSA1 and BFP460H6327XTSA1 require voltage and power budget verification. BFR380L3E6327XTMA1 requires package footprint redesign (SOT-883 vs. SOT-23-3). MAPR-000912-500S00 and MRF448 require complete circuit topology redesign due to chassis mount configuration.

Q7: How do noise figure specifications compare across substitutes?

2SC3583-T1B-A specifies 1.2dB @ 1GHz. BFP420H6327XTSA1 provides 1.1dB @ 1.8GHz (lower noise). BFP460H6327XTSA1 provides 0.7–1.2dB @ 100MHz–3GHz (lower noise across broader range). BFR380L3E6327XTMA1 provides 0.5–2.1dB @ 1.8GHz (variable across frequency). MAPR-000912-500S00 and MRF448 do not specify noise figure, indicating application focus on power amplification rather than low-noise reception.
