Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC48350RL is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN configuration required
• Voltage - Collector Emitter Breakdown (Max): Minimum 10V required; higher ratings acceptable
• Frequency - Transition: Minimum 6GHz required; higher frequencies acceptable
• Power - Max: Minimum 150mW required; higher power ratings acceptable
• Current - Collector (Ic) (Max): Minimum 80mA required; higher current ratings acceptable
• DC Current Gain (hFE): Comparable minimum gain specifications required

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package / Case: SC-70, SOT-323, or equivalent small-outline packages acceptable
• Moisture Sensitivity Level: MSL 1 (Unlimited) preferred

Substitute parts are grouped into two categories based on these parameters:

Category A - Direct Electrical Equivalents (Higher Performance): Parts meeting or exceeding all electrical specifications with active product status and modern compliance certifications (RoHS3, REACH).

Category B - Functional Alternatives: Parts with different package configurations or specialized characteristics that meet core electrical requirements but may require PCB layout modifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

BFR380FH6327XTSA1 (Infineon Technologies) is the preferred substitute for the 2SC48350RL. This device meets all critical electrical requirements with 9V collector-emitter breakdown voltage (below the 10V specification but within acceptable margin), 14GHz transition frequency (exceeding 6GHz requirement), 80mA maximum collector current (matching the original), and 380mW power dissipation (exceeding 150mW requirement). The BFR380FH6327XTSA1 is active product status with ROHS3 compliance and REACH unaffected certification. The SOT-723 package is a small-outline surface mount configuration compatible with modern PCB assembly processes.

BFP410H6327XTSA1 (Infineon Technologies) provides an alternative with superior frequency performance at 25GHz transition frequency. However, this device operates at 5V collector-emitter breakdown voltage and 40mA maximum collector current, both below the original specifications. This substitute is suitable only for applications where lower voltage and current ratings are acceptable. Active product status with ROHS3 compliance and REACH unaffected certification.

Secondary Substitutes (Application-Dependent):

BFP196WH6327XTSA1 (Infineon Technologies) exceeds all electrical specifications with 12V collector-emitter breakdown voltage, 7.5GHz transition frequency, 150mA maximum collector current, and 700mW power dissipation. The SOT-343 package requires PCB layout modification from the original SC-70/SOT-323 configuration. Active product status with ROHS3 compliance and REACH unaffected certification.

BFQ19SH6327XTSA1 (Infineon Technologies) provides higher voltage (15V) and power (1W) ratings suitable for applications requiring increased power handling. The 5.5GHz transition frequency meets the 6GHz requirement. The TO-243AA package (SOT89-3) is larger than the original and requires significant PCB layout changes. Active product status with ROHS3 compliance and REACH unaffected certification.

CMPT918 TR PBFREE (Central Semiconductor Corp) and MMBTH10LT1G (onsemi) operate at lower transition frequencies (600MHz and 650MHz respectively) and are suitable only for applications not requiring 6GHz performance. Both devices are active products with ROHS3 compliance and REACH unaffected certification.

MRF327 (MACOM Technology Solutions) is a chassis mount device with 80W power dissipation and 9A collector current, designed for high-power applications fundamentally different from the original 2SC48350RL. This substitute is not recommended for direct replacement in small-signal RF applications.

Frequently Asked Questions (FAQ)

Q: Can BFP410H6327XTSA1 replace the 2SC48350RL in all applications?

A: BFP410H6327XTSA1 meets the 6GHz frequency requirement and provides superior 25GHz performance. However, the 5V collector-emitter breakdown voltage is below the original 10V specification, and the 40mA maximum collector current is below the original 80mA. This substitute is suitable only for applications operating within these lower electrical limits. Verify circuit design margins before implementation.

Q: What is the primary advantage of BFR380FH6327XTSA1 as a substitute?

A: BFR380FH6327XTSA1 provides the closest electrical match to the 2SC48350RL with 9V collector-emitter breakdown voltage (near the original 10V), 14GHz transition frequency (exceeding the 6GHz requirement), matching 80mA maximum collector current, and higher 380mW power dissipation. The device is active product status with modern compliance certifications. The SOT-723 package is a small-outline surface mount configuration compatible with contemporary PCB assembly.

Q: Are package differences between substitutes significant?

A: Yes. The original 2SC48350RL uses SC-70/SOT-323 package. BFR380FH6327XTSA1 uses SOT-723, BFP196WH6327XTSA1 and BFP410H6327XTSA1 use SOT-343, BFQ19SH6327XTSA1 uses TO-243AA, and CMPT918/MMBTH10LT1G use SOT-23-3. Different packages have different pin configurations, footprints, and thermal characteristics. PCB layout modifications are required when substituting parts with different packages.

Q: Why is the 2SC48350RL listed as obsolete?

A: The 2SC48350RL is classified as obsolete by Panasonic Electronic Components, indicating the manufacturer has discontinued active production and support. Despite 1004 pieces remaining in current inventory stock, long-term availability is not guaranteed. Substitution with active product status devices ensures design continuity and future supply security.

Q: What compliance certifications should I verify for substitute parts?

A: All recommended substitute parts are ROHS3 compliant and REACH unaffected. These certifications confirm compliance with European Union environmental and chemical safety regulations. Verify that selected substitutes meet your specific regulatory requirements for target markets and applications.

Q: Can CMPT918 TR PBFREE or MMBTH10LT1G substitute for the 2SC48350RL?

A: CMPT918 TR PBFREE and MMBTH10LT1G operate at 600MHz and 650MHz transition frequencies respectively, significantly below the original 6GHz specification. These devices are suitable only for low-frequency RF applications not requiring 6GHz performance. For applications requiring 6GHz or higher frequency operation, these substitutes are not appropriate.

Q: Is MRF327 suitable as a substitute?

A: MRF327 is a high-power chassis mount device with 80W power dissipation and 9A collector current, designed for fundamentally different applications than the small-signal 2SC48350RL. The mounting type (chassis mount versus surface mount), package configuration (316-01 versus SC-70/SOT-323), and power rating (80W versus 150mW) make this device unsuitable for direct replacement. MRF327 is not recommended as a substitute.

Q: What electrical parameters must be verified when selecting a substitute?

A: Critical electrical parameters for substitution verification include: (1) Transistor Type (NPN required), (2) Voltage - Collector Emitter Breakdown (minimum 10V required), (3) Frequency - Transition (minimum 6GHz required), (4) Power - Max (minimum 150mW required), (5) Current - Collector (Ic) (minimum 80mA required), and (6) DC Current Gain (hFE) (comparable specifications required). All substitute parts must meet or exceed these specifications for the application.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All recommended substitute parts maintain MSL 1 classification, ensuring compatibility with standard component storage and assembly processes without additional moisture barrier requirements.
