Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFS17PE6327HTSA1 is determined by the following critical parameters: transistor type (NPN), collector-emitter breakdown voltage (15V maximum), transition frequency capability (1.4GHz minimum for direct replacement), maximum power dissipation (280mW minimum), maximum collector current (25mA minimum), and package compatibility (SOT-23-3 surface mount). Substitute parts must maintain electrical compatibility within these specified ranges while meeting RoHS3 compliance and moisture sensitivity requirements.

The substitute parts identified fall into two distinct categories based on application requirements:

Category 1: Direct Electrical Equivalents (SOT-23-3 Package) Parts maintaining the same package form factor and voltage rating with enhanced or equivalent frequency and power specifications.

Category 2: Higher Performance Alternatives (Different Package) Parts offering superior electrical performance characteristics with different package configurations, suitable for applications where package constraints are flexible.

Parameter Comparison

Engineering Selection Recommendations

BFR106E6327HTSA1 (Infineon Technologies) This substitute maintains identical voltage rating (15V), package form factor (SOT-23-3), and operating temperature (150°C) while providing enhanced performance specifications. Transition frequency increases to 5GHz, power dissipation capability increases to 700mW, and collector current capacity increases to 210mA. The device carries Active product status and ROHS3 compliance. This part is suitable for applications requiring higher frequency operation or increased power handling within the same physical footprint.

MAX2602ESA+T (Analog Devices Inc./Maxim Integrated) This substitute maintains identical voltage rating (15V) and operating temperature (150°C) with a different package configuration (8-SOIC-EP). Transition frequency is 1GHz with power dissipation of 6.4W and collector current capacity of 1.2A. The device carries Active product status and ROHS3 compliance. This part is suitable for applications requiring significantly higher power dissipation and current handling, with package constraints permitting the larger 8-SOIC form factor.

MMBT918LT1G (onsemi) This substitute maintains identical voltage rating (15V) and package form factor (SOT-23-3) with lower transition frequency (600MHz) and power dissipation (225mW). Operating temperature range extends to -55°C minimum. The device carries Active product status and ROHS3 compliance. This part is suitable for lower frequency applications where the reduced specifications align with circuit requirements.

MAPRST0912-50 (MACOM Technology Solutions) This substitute provides higher voltage rating (65V) with significantly enhanced power dissipation (50W) and collector current capacity (5.3A). Mounting type is Chassis Mount rather than surface mount. Operating temperature maximum is 200°C. The device carries ROHS3 compliance and Active product status. This part is suitable for high-power applications with different thermal and mechanical mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can BFR106E6327HTSA1 be used as a direct replacement for BFS17PE6327HTSA1? A: BFR106E6327HTSA1 is electrically compatible as a substitute. Both devices share identical voltage rating (15V), package form factor (SOT-23-3), and operating temperature (150°C). BFR106E6327HTSA1 provides enhanced specifications in frequency (5GHz vs. 1.4GHz), power (700mW vs. 280mW), and current (210mA vs. 25mA). Circuit validation is required to confirm performance alignment with application requirements.

Q: What are the package compatibility constraints for substitution? A: BFS17PE6327HTSA1 is specified in TO-236-3, SC-59, SOT-23-3 surface mount package. Direct package-compatible substitutes are BFR106E6327HTSA1 and MMBT918LT1G, both in SOT-23-3. MAX2602ESA+T uses 8-SOIC-EP package and requires PCB layout modification. MAPRST0912-50 uses Chassis Mount configuration and requires different mechanical integration.

Q: Are all substitute parts RoHS3 compliant? A: All identified substitute parts carry ROHS3 Compliant status: BFR106E6327HTSA1, MAX2602ESA+T, MMBT918LT1G, and MAPRST0912-50.

Q: What is the significance of the "Not For New Designs" status of BFS17PE6327HTSA1? A: This status indicates the device has reached end-of-life and is no longer recommended for new circuit designs. Existing inventory remains available, but long-term supply cannot be guaranteed. Substitution with Active status parts (BFR106E6327HTSA1, MAX2602ESA+T, MMBT918LT1G, or MAPRST0912-50) ensures design continuity and future component availability.

Q: How do noise figure specifications compare across substitute parts? A: BFS17PE6327HTSA1 specifies 3.5dB ~ 5dB @ 800MHz. BFR106E6327HTSA1 provides improved noise figure of 1.8dB ~ 3dB @ 900MHz ~ 1.8GHz. MAX2602ESA+T specifies 3.3dB @ 836MHz. MMBT918LT1G specifies 6dB @ 60MHz. MAPRST0912-50 does not specify noise figure. Selection depends on application frequency and noise performance requirements.

Q: What collector current capacity differences exist among substitutes? A: BFS17PE6327HTSA1 maximum collector current is 25mA. BFR106E6327HTSA1 provides 210mA. MAX2602ESA+T provides 1.2A. MMBT918LT1G provides 50mA. MAPRST0912-50 provides 5.3A. Selection must align with circuit current requirements and thermal management capabilities.

Q: Can MMBT918LT1G be used in applications requiring 1.4GHz operation? A: MMBT918LT1G has transition frequency of 600MHz, which is below the 1.4GHz specification of BFS17PE6327HTSA1. This part is not suitable for applications requiring 1.4GHz or higher frequency operation. BFR106E6327HTSA1 (5GHz) or MAX2602ESA+T (1GHz) would be more appropriate for higher frequency requirements.

Q: What are the thermal operating range differences? A: BFS17PE6327HTSA1 operates to 150°C maximum junction temperature. MMBT918LT1G extends the minimum operating temperature to -55°C, providing wider temperature range (-55°C ~ 150°C). MAPRST0912-50 operates to 200°C maximum. Application environment determines thermal requirement compatibility.
