MPSH10_D74Z Equivalent & Substitute Parts

Part Overview

The MPSH10_D74Z is an RF transistor NPN manufactured by onsemi, rated for 25V collector-emitter breakdown voltage with a transition frequency of 650MHz and maximum power dissipation of 350mW. This device is packaged in a through-hole TO-92-3 configuration and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance where the MPSH10_D74Z is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSH10_D74Z is determined by the following critical parameters: transistor type (NPN), collector-emitter breakdown voltage rating, transition frequency capability, maximum power dissipation, maximum collector current, and operating temperature range. The substitute parts listed have been identified based on compatibility within these electrical specifications and their active product status.

The substitute parts are grouped into two categories:

Category 1: High-Frequency Surface Mount RF Transistors (Infineon Technologies) These parts operate at significantly higher transition frequencies (8GHz to 46GHz) compared to the MPSH10_D74Z (650MHz). They are suitable for applications requiring higher frequency performance but with reduced voltage ratings and power dissipation in most cases. These devices use surface mount packaging (SOT-343 or SOT-723) rather than through-hole configuration.

Category 2: High-Power Chassis Mount RF Transistors (MACOM Technology Solutions) These parts are rated for higher voltage (65V) and significantly higher power dissipation (50W to 170W) with higher collector current ratings (5.3A to 27A). They are suitable for high-power RF applications but use chassis mount packaging rather than through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: No direct through-hole equivalent exists among the listed substitute parts. All substitute parts use either surface mount or chassis mount packaging, requiring circuit board redesign or adapter solutions.

For High-Frequency RF Applications (650MHz and above): The Infineon Technologies parts (BF776H6327XTSA1, BFP520H6327XTSA1, BFR193FH6327XTSA1) are active products with ROHS3 compliance. Selection among these depends on specific voltage and power requirements:

• BF776H6327XTSA1: 4.7V rating, 46GHz transition frequency, 200mW power
• BFP520H6327XTSA1: 3.5V rating, 45GHz transition frequency, 100mW power
• BFR193FH6327XTSA1: 12V rating, 8GHz transition frequency, 580mW power

For High-Power RF Applications: The MACOM Technology Solutions parts (MAPR-002729-170M00, MAPRST0912-50) are active products with ROHS3 compliance and higher voltage ratings (65V). These are suitable for applications requiring power levels significantly exceeding the MPSH10_D74Z specification.

All substitute parts listed are active products with REACH Unaffected status and ECCN EAR99 classification, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can the BF776H6327XTSA1 directly replace the MPSH10_D74Z in an existing circuit?

A: No. While both are NPN RF transistors, the BF776H6327XTSA1 has a significantly lower voltage rating (4.7V versus 25V), higher transition frequency (46GHz versus 650MHz), and uses surface mount packaging (SOT-343) instead of through-hole (TO-92-3). Circuit redesign is required.

Q: What is the primary limitation when substituting the MPSH10_D74Z with the Infineon parts?

A: The primary limitation is packaging. The MPSH10_D74Z uses through-hole TO-92-3 packaging, while all Infineon substitute parts use surface mount packaging (SOT-343 or SOT-723). This requires PCB redesign or the use of adapter solutions.

Q: Are the MACOM parts suitable for low-frequency applications?

A: The MACOM parts (MAPR-002729-170M00 and MAPRST0912-50) do not have specified transition frequency values in the provided data. These parts are designed for high-power RF applications with voltage ratings of 65V and power dissipation of 50W to 170W, significantly exceeding the MPSH10_D74Z specifications.

Q: What compliance certifications do the substitute parts carry?

A: All active substitute parts listed carry ROHS3 compliance and REACH Unaffected status, matching the compliance profile of the MPSH10_D74Z. All parts are classified as ECCN EAR99.

Q: Which substitute part most closely matches the voltage rating of the MPSH10_D74Z?

A: The BFR193FH6327XTSA1 has a voltage rating of 12V, which is the closest to the MPSH10_D74Z rating of 25V among the Infineon parts. However, it operates at 8GHz transition frequency compared to 650MHz for the original part.

Q: Can the MPSH10_D74Z be used in applications requiring 46GHz operation?

A: No. The MPSH10_D74Z has a transition frequency of 650MHz and is not suitable for applications requiring 46GHz operation. The BF776H6327XTSA1 or BFP520H6327XTSA1 would be required for such applications.

Q: What is the inventory status of these substitute parts?

A: All substitute parts listed have active inventory: BF776H6327XTSA1 (1490 Pcs), BFP520H6327XTSA1 (35200 Pcs), BFR193FH6327XTSA1 (3095 Pcs), MAPR-002729-170M00 (788 Pcs), and MAPRST0912-50 (1028 Pcs).
