Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX2602ESA is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Primary Substitution Criteria:

• Transistor Type: NPN configuration required
• Voltage - Collector Emitter Breakdown: Must equal or exceed 15V
• Frequency - Transition: Must support 1GHz or higher operation
• Power - Max: Must support 6.4W or greater dissipation
• Current - Collector (Ic) Max: Must support 1.2A or greater
• Mounting Type: Surface Mount required
• Operating Temperature: Must support 150°C (TJ) or higher
• RoHS Compliance: ROHS3 Compliant status required

Secondary Compatibility Factors:

• Package compatibility or functional equivalence in circuit design
• Noise Figure and Gain characteristics within acceptable operational ranges
• DC Current Gain (hFE) specifications suitable for RF amplification circuits

The substitute parts listed below are grouped based on their adherence to these electrical and mechanical parameters as explicitly provided in the component specifications.

Engineering Selection Recommendations

MAX2602ESA+ (Direct Packaging Variant)

The MAX2602ESA+ is the primary direct substitute for the MAX2602ESA. Both components share identical electrical specifications and package configuration (8-SOIC with exposed pad). The MAX2602ESA+ maintains Active product status, ensuring ongoing availability and supply chain support. This variant differs only in packaging format (Tube versus standard packaging) and represents the recommended replacement for obsolete MAX2602ESA inventory. Inventory availability of 1127 pieces supports production requirements. ROHS3 compliance and MSL 1 rating match the original specification.

BFQ19SH6327XTSA1 (Infineon Technologies)

The BFQ19SH6327XTSA1 is an active RF transistor from Infineon Technologies suitable for applications where higher frequency operation (5.5GHz) is acceptable. This component meets the 15V voltage requirement and 150°C operating temperature specification. However, the maximum collector current (120mA) and power dissipation (1W) are significantly lower than the MAX2602ESA (1.2A, 6.4W), restricting its use to lower-power RF circuits. The gain specification (7dB) is lower than the original part. ROHS3 compliance and MSL 1 rating are maintained. Package format (TO-243AA) differs from the original 8-SOIC.

BFR380FH6327XTSA1 (Infineon Technologies)

The BFR380FH6327XTSA1 is an active RF transistor optimized for high-frequency applications (14GHz transition frequency). This component does not meet the 15V voltage requirement, with a maximum collector-emitter breakdown voltage of only 9V. The maximum collector current (80mA) and power dissipation (380mW) are substantially lower than the MAX2602ESA specifications. This part is suitable only for low-voltage, low-power RF applications and is not recommended as a direct substitute for the MAX2602ESA in standard 15V circuits. ROHS3 compliance and MSL 1 rating are maintained. Package format (SOT-723) differs significantly from the original 8-SOIC.

2SC4915-Y,LF (Toshiba Semiconductor and Storage)

The 2SC4915-Y,LF is an active RF transistor from Toshiba with higher voltage rating (30V) than the MAX2602ESA. However, this component operates at 550MHz transition frequency, which is below the 1GHz specification of the original part. The maximum collector current (20mA) and power dissipation (100mW) are significantly lower than required. The operating temperature maximum (125°C) is below the 150°C specification of the MAX2602ESA. This part is not suitable as a substitute for applications requiring 1GHz operation or higher power dissipation. RoHS compliance is maintained. Package format (SC-75, SOT-416) differs from the original 8-SOIC.

MRF327 (MACOM Technology Solutions)

The MRF327 is an active RF transistor from MACOM with high voltage rating (33V) and high power capability (80W), exceeding the MAX2602ESA specifications. However, this component uses Chassis Mount packaging (316-01 style), which is incompatible with the surface mount PCB assembly requirements of the original 8-SOIC package. Transition frequency and noise figure specifications are not provided for this component. The mounting type difference makes this part unsuitable for direct PCB substitution in surface mount applications. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q1: Can MAX2602ESA+ be used as a direct replacement for MAX2602ESA?

A: Yes. The MAX2602ESA+ is the direct substitute for the obsolete MAX2602ESA. Both components share identical electrical specifications (15V, 1GHz, 6.4W, 1.2A), the same 8-SOIC package with exposed pad, and equivalent RoHS/MSL compliance. The only difference is packaging format (Tube). No circuit modifications are required.

Q2: What are the key limitations when considering BFQ19SH6327XTSA1 as a substitute?

A: The BFQ19SH6327XTSA1 has three significant limitations: (1) Maximum collector current of 120mA versus 1.2A required, (2) Maximum power dissipation of 1W versus 6.4W required, and (3) Different package format (TO-243AA versus 8-SOIC). This part is suitable only for low-power RF applications operating below 1.2A collector current and 6.4W power dissipation.

Q3: Why is BFR380FH6327XTSA1 not recommended as a substitute?

A: The BFR380FH6327XTSA1 does not meet the voltage requirement of the MAX2602ESA. With a maximum collector-emitter breakdown voltage of 9V, it cannot operate safely in circuits designed for 15V operation. Additionally, the maximum collector current (80mA) and power dissipation (380mW) are substantially below the original specification (1.2A, 6.4W).

Q4: Can 2SC4915-Y,LF replace MAX2602ESA in 1GHz RF applications?

A: No. The 2SC4915-Y,LF operates at 550MHz transition frequency, which is below the 1GHz requirement. Additionally, the maximum collector current (20mA) and power dissipation (100mW) are insufficient for applications requiring 1.2A and 6.4W. The operating temperature maximum (125°C) is also below the 150°C specification.

Q5: Is MRF327 suitable for surface mount PCB applications?

A: No. The MRF327 uses Chassis Mount packaging (316-01 style), which is incompatible with surface mount PCB assembly. The original MAX2602ESA uses 8-SOIC surface mount package. MRF327 is designed for through-hole or chassis-mounted applications only.

Q6: What parameters must a substitute part meet to be compatible with MAX2602ESA circuits?

A: A valid substitute must meet all of the following criteria: (1) NPN transistor type, (2) Collector-emitter breakdown voltage of 15V or higher, (3) Transition frequency of 1GHz or higher, (4) Maximum collector current of 1.2A or higher, (5) Maximum power dissipation of 6.4W or higher, (6) Operating temperature rating of 150°C (TJ) or higher, (7) Surface mount packaging, and (8) ROHS3 compliance.

Q7: Are there any compliance or certification differences between the substitute parts?

A: All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original MAX2602ESA specification. All parts carry EAR99 ECCN classification. No compliance or certification barriers exist for substitution from a regulatory standpoint.

Q8: What is the primary reason MAX2602ESA is obsolete?

A: The MAX2602ESA is listed as obsolete product status. The MAX2602ESA+ (Active status) is the direct replacement, offering identical electrical and mechanical specifications with ongoing manufacturer support and supply availability.
