Key Parameters

Substitute Part Grouping Explanation

Substitution of RF transistor NPN devices is determined by compatibility across the following critical parameters: transistor type (NPN), operating temperature range (150°C maximum junction temperature), surface mount mounting type, and electrical performance characteristics including voltage rating, frequency capability, power dissipation, collector current rating, and DC current gain.

The substitute parts listed below are grouped based on their ability to meet or exceed the electrical specifications of the KSC2756OMTF within the constraints of their respective package configurations and product status. All substitute parts maintain NPN transistor type, 150°C operating temperature capability, and surface mount configuration. Substitution feasibility depends on application-specific requirements for voltage rating, frequency response, power handling, and current capacity.

Critical Parameters for Substitution:

• Transistor Type: NPN
• Operating Temperature: 150°C (TJ)
• Mounting Type: Surface Mount
• Voltage - Collector Emitter Breakdown (Max)
• Frequency - Transition
• Power - Max
• Current - Collector (Ic) (Max)
• DC Current Gain (hFE)

Engineering Selection Recommendations

All substitute parts listed are manufactured by Infineon Technologies and maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete KSC2756OMTF. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

BFR193L3E6327XTMA1 provides the closest voltage rating match at 12V collector-emitter breakdown voltage, exceeding the 20V specification of the KSC2756OMTF. This part offers significantly enhanced frequency capability at 8GHz, increased power dissipation at 580mW, and higher collector current capacity at 80mA. The BFR193L3E6327XTMA1 is suitable for applications requiring higher power handling and frequency performance within a lower voltage envelope.

BFR460L3E6327XTMA1 operates at 5.8V collector-emitter breakdown voltage with 22GHz transition frequency and 200mW power rating. This part is applicable to low-voltage RF applications with enhanced frequency response.

BFP405H6740XTSA1 and BFP640ESDH6327XTSA1 operate at reduced voltage ratings (5V and 4.7V respectively) with significantly higher transition frequencies (25GHz and 46GHz). These parts are suitable for ultra-high-frequency applications where voltage constraints are compatible with circuit design requirements.

Package configuration differences exist across substitute parts. The KSC2756OMTF uses SOT-23-3 packaging, while substitute parts employ SOT-883 (BFR460L3E6327XTMA1, BFR193L3E6327XTMA1) or SOT-343 (BFP405H6740XTSA1, BFP640ESDH6327XTSA1) configurations. PCB layout and footprint modifications are required when implementing substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the BFR193L3E6327XTMA1 directly replace the KSC2756OMTF in existing designs?

A: Direct replacement requires evaluation of voltage rating compatibility. The BFR193L3E6327XTMA1 operates at 12V maximum collector-emitter breakdown voltage, which is lower than the KSC2756OMTF specification of 20V. If the application circuit operates above 12V, this substitute is not suitable. Additionally, package configuration differs (SOT-883 versus SOT-23-3), requiring PCB footprint modification.

Q: What are the key differences between the substitute parts?

A: The substitute parts differ primarily in voltage rating, frequency capability, and power dissipation. BFR193L3E6327XTMA1 offers the highest power rating at 580mW and lowest frequency at 8GHz. BFP640ESDH6327XTSA1 provides the highest frequency capability at 46GHz but operates at the lowest voltage rating of 4.7V. Selection depends on application-specific requirements for voltage, frequency, and power handling.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original KSC2756OMTF RoHS status is not specified in the provided data. All substitute parts and the original part are REACH unaffected.

Q: What package considerations apply when substituting parts?

A: The KSC2756OMTF uses SOT-23-3 surface mount packaging. Substitute parts employ either SOT-883 or SOT-343 configurations. These package types have different footprint dimensions and pin configurations. PCB layout redesign and re-qualification are required when implementing substitute parts with different package types.

Q: Which substitute part offers the best overall performance upgrade?

A: Performance upgrade depends on application requirements. The BFR193L3E6327XTMA1 provides enhanced power dissipation (580mW versus 150mW) and frequency capability (8GHz versus 850MHz) while maintaining reasonable voltage rating (12V). The BFP640ESDH6327XTSA1 offers the highest frequency capability (46GHz) for ultra-high-frequency applications but operates at reduced voltage (4.7V).

Q: Are moisture sensitivity levels equivalent across all parts?

A: All parts, including the original KSC2756OMTF and all substitute parts, maintain MSL 1 (Unlimited) moisture sensitivity level, indicating equivalent moisture handling requirements and storage conditions.

Q: What is the inventory status of substitute parts?

A: All substitute parts maintain active product status with current inventory availability. BFR193L3E6327XTMA1 has 882 pieces in stock, BFR460L3E6327XTMA1 has 15,872 pieces, BFP405H6740XTSA1 has 914 pieces, and BFP640ESDH6327XTSA1 has 1,225 pieces available.
