Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCH4020-TL-E is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Transistor type must be NPN
• Mounting type must be surface mount
• Moisture sensitivity level must be 1 (Unlimited) or equivalent
• Collector-emitter breakdown voltage must equal or exceed 8V
• Transition frequency must equal or exceed 16GHz
• Maximum power dissipation must equal or exceed 400mW
• Maximum collector current must equal or exceed 150mA

Secondary Compatibility Factors:

• Package compatibility with SOT-343F or equivalent footprint
• Operating temperature range must support 150°C junction temperature
• Compliance certifications (REACH, RoHS status)

The substitute parts identified (2SC5087R and BFP183WH6327XTSA1) are grouped as functional equivalents based on their NPN configuration, surface mount technology, and RF performance characteristics. However, each substitute exhibits trade-offs in specific parameters that must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2SC5087R(TE85L,F) directly replace the MCH4020-TL-E in all applications?

A: No. The 2SC5087R operates at 8GHz transition frequency compared to the MCH4020-TL-E's 16GHz, representing a 50% reduction in frequency capability. Additionally, maximum power dissipation is limited to 150mW versus 400mW, and maximum collector current is 80mA versus 150mA. This substitute is suitable only for applications where these reduced specifications meet design requirements. Package footprint differs (SC-61AA versus SOT-343F), requiring PCB layout verification.

Q: Is the BFP183WH6327XTSA1 a better substitute than the 2SC5087R?

A: The BFP183WH6327XTSA1 offers advantages in specific parameters: higher power dissipation (450mW versus 150mW), maintained operating temperature (150°C versus 125°C), improved gain (22dB versus unspecified), and better noise figure (0.9dB ~ 1.4dB versus 1.1dB ~ 2dB). However, it also exhibits reduced transition frequency (8.5GHz versus 8GHz) and lower maximum collector current (65mA versus 80mA) compared to the 2SC5087R. Selection depends on application-specific requirements for frequency response, power handling, and noise performance.

Q: What is the primary limitation when substituting either part for the MCH4020-TL-E?

A: The primary limitation is transition frequency. The MCH4020-TL-E operates at 16GHz, while both substitutes operate at 8GHz or 8.5GHz. Applications requiring RF performance above 8.5GHz cannot use these substitutes. Additionally, both substitutes have reduced maximum collector current capacity (80mA and 65mA respectively versus 150mA), which may limit output power capability in certain circuit topologies.

Q: Are the package footprints compatible between these three parts?

A: The MCH4020-TL-E uses SOT-343F (4-MCPH). The 2SC5087R uses SC-61AA (SMQ), which is not directly compatible. The BFP183WH6327XTSA1 uses SC-82A or SOT-343, with SOT-343 being compatible with SOT-343F footprints. PCB layout verification is required before substitution, particularly for the 2SC5087R.

Q: What compliance certifications should be considered when selecting a substitute?

A: All three parts carry ECCN EAR99 classification. The MCH4020-TL-E is REACH Unaffected. The 2SC5087R is RoHS Compliant. The BFP183WH6327XTSA1 is ROHS3 Compliant and REACH Unaffected. For applications requiring RoHS compliance, the 2SC5087R and BFP183WH6327XTSA1 are suitable; the original MCH4020-TL-E is not. For REACH-regulated applications, the MCH4020-TL-E and BFP183WH6327XTSA1 are suitable.

Q: What is the moisture sensitivity level for all three parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Which substitute offers the best overall performance match to the MCH4020-TL-E?

A: Neither substitute fully matches the MCH4020-TL-E across all parameters. The BFP183WH6327XTSA1 provides the closest match in power dissipation (450mW versus 400mW), operating temperature (150°C), and package compatibility (SOT-343). However, it sacrifices 46.9% of the transition frequency capability. The 2SC5087R sacrifices even more frequency capability but offers higher collector current capacity than the BFP183WH6327XTSA1. Selection must prioritize the specific performance parameters critical to the target application.
