Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMPQ3904 TR13 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Transistor configuration: 4 NPN (Quad)
• Maximum collector current: 200mA
• Collector-emitter breakdown voltage: 40V
• Vce saturation: 300mV @ 5mA, 50mA
• DC current gain (hFE): 100 @ 10mA, 1V
• Maximum power dissipation: 1W
• Operating temperature range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package: 16-SOIC (0.154", 3.90mm Width)

The transition frequency parameter (450MHz for the main part) is not a substitution-limiting criterion when all other electrical and mechanical specifications are met. Substitute parts may operate at different transition frequencies provided all other parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

The MMPQ3904 manufactured by onsemi is a direct electrical and mechanical equivalent to the MMPQ3904 TR13 from Central Semiconductor Corp. All critical electrical parameters—collector current, breakdown voltage, saturation voltage, current gain, power rating, and operating temperature range—are identical.

Product Status Consideration: The onsemi MMPQ3904 carries an Active product status, ensuring ongoing availability and manufacturing support. The Central Semiconductor version is classified as Obsolete, making the onsemi substitute the appropriate choice for new designs and continued production.

Compliance Consideration: The onsemi MMPQ3904 is ROHS3 compliant, whereas the Central Semiconductor version is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the onsemi part satisfies these requirements.

Moisture Sensitivity Consideration: The onsemi part carries MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the Central Semiconductor part. This difference requires appropriate handling and storage protocols during manufacturing and assembly operations.

The onsemi MMPQ3904 is suitable for direct substitution in all applications where the Central Semiconductor MMPQ3904 TR13 was previously specified.

Frequently Asked Questions (FAQ)

Q: Can the onsemi MMPQ3904 replace the Central Semiconductor MMPQ3904 TR13 in existing designs?

A: Yes. The onsemi MMPQ3904 meets all electrical and mechanical specifications of the Central Semiconductor part. Electrical parameters including collector current, breakdown voltage, saturation voltage, current gain, power dissipation, and operating temperature are identical. Both parts use the 16-SOIC surface mount package with matching pinout and footprint.

Q: What is the significance of the different transition frequencies (450MHz vs. 250MHz)?

A: The transition frequency difference does not prevent substitution. Both parts meet the specified DC current gain and saturation voltage requirements. The transition frequency parameter indicates the frequency at which current gain begins to decrease; however, this specification does not limit substitution when all other electrical parameters are equivalent and the application does not require operation at frequencies approaching the transition frequency limit.

Q: Does the MSL 3 rating of the onsemi part affect substitution suitability?

A: The MSL 3 (168 Hours) rating requires adherence to specific moisture handling and storage protocols during manufacturing and assembly. This does not affect electrical or mechanical compatibility. Organizations must implement appropriate moisture control measures consistent with IPC standards for MSL 3 components.

Q: Are the pinout and footprint identical between these parts?

A: Yes. Both the Central Semiconductor MMPQ3904 TR13 and the onsemi MMPQ3904 use the 16-SOIC package with 0.154" width (3.90mm). Pinout and PCB footprint are identical, enabling direct substitution without layout modifications.

Q: Why is the onsemi part recommended over the Central Semiconductor part?

A: The onsemi MMPQ3904 is classified as Active, ensuring continued manufacturing and supply availability. The Central Semiconductor version is Obsolete. Additionally, the onsemi part is ROHS3 compliant, supporting regulatory requirements and customer specifications. For new designs and ongoing production, the onsemi part provides superior supply chain continuity and compliance assurance.

Q: Can both parts be used interchangeably in the same production batch?

A: Yes, provided that moisture handling protocols appropriate for MSL 3 components are implemented for the onsemi part. Both parts are electrically and mechanically equivalent. However, maintaining consistent sourcing from a single manufacturer is recommended to ensure supply chain stability and simplify quality control documentation.
