MPQ2907 PBFREE Equivalent & Substitute Parts

Part Overview

The MPQ2907 PBFREE is a Bipolar (BJT) Transistor Array containing 4 PNP transistors in a Through Hole TO-116 package. This component is classified as Obsolete, which necessitates identification of functionally equivalent substitute parts for ongoing design support and procurement. The MPQ2907 PBFREE was manufactured by Central Semiconductor Corp and is ROHS3 compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ2907 PBFREE is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration must remain 4 PNP (Quad)
• Maximum collector current must equal or exceed 600mA
• Voltage rating must equal or exceed 40V collector-emitter breakdown voltage
• Saturation voltage characteristics must be compatible with circuit requirements
• Transition frequency must support the intended switching speed application

Mechanical Compatibility Criteria:

• Package type determines PCB layout compatibility
• Pin configuration must match or be adaptable through design modification
• Thermal characteristics (power dissipation) must meet or exceed 650mW requirement

The MMPQ2907A manufactured by onsemi meets the electrical requirements for substitution. However, this part differs in mounting technology (Surface Mount 16-SOIC versus Through Hole 14-DIP), which represents a mechanical incompatibility requiring PCB redesign or adapter solutions.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MPQ2907 PBFREE is classified as Obsolete. The MMPQ2907A is classified as Active, making it the primary candidate for new designs and long-term procurement continuity.

Compliance and Certification: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. Both are REACH unaffected. Compliance requirements are satisfied by the MMPQ2907A substitute.

Electrical Substitution Feasibility: The MMPQ2907A provides electrical equivalence with enhanced specifications across all critical parameters: higher voltage rating (60V versus 40V), improved power dissipation (1W versus 650mW), higher transition frequency (250MHz versus 200MHz), and superior DC current gain (100 versus 50). These enhancements ensure functional compatibility in applications designed for the MPQ2907 PBFREE.

Mechanical Substitution Constraints: Direct mechanical substitution is not possible. The MPQ2907 PBFREE uses Through Hole 14-DIP packaging, while the MMPQ2907A uses Surface Mount 16-SOIC packaging. PCB redesign is required for implementation of the MMPQ2907A substitute.

Moisture Sensitivity Consideration: The MPQ2907 PBFREE has MSL 1 (unlimited shelf life). The MMPQ2907A has MSL 3 (168-hour floor life after moisture exposure). Storage and handling procedures must be adjusted accordingly.

Temperature Range Consideration: The MPQ2907 PBFREE operates from -65°C to 150°C. The MMPQ2907A operates from -55°C to 150°C. Applications requiring operation below -55°C cannot use the MMPQ2907A substitute.

Frequently Asked Questions (FAQ)

Q: Can the MMPQ2907A be used as a direct replacement for the MPQ2907 PBFREE without PCB modification?

A: No. The MMPQ2907A uses Surface Mount 16-SOIC packaging while the MPQ2907 PBFREE uses Through Hole 14-DIP packaging. Direct socket substitution is not possible. PCB redesign or adapter solutions are required.

Q: Are the electrical characteristics of the MMPQ2907A compatible with circuits designed for the MPQ2907 PBFREE?

A: Yes, from an electrical standpoint. The MMPQ2907A meets or exceeds all critical electrical parameters of the MPQ2907 PBFREE, including collector current (600mA), voltage rating (60V versus 40V), saturation voltage, and transition frequency (250MHz versus 200MHz).

Q: What is the impact of the different moisture sensitivity levels?

A: The MPQ2907 PBFREE has MSL 1 (unlimited shelf life), while the MMPQ2907A has MSL 3 (168-hour floor life after moisture exposure). The MMPQ2907A requires more stringent moisture control during storage and handling. Baking procedures may be necessary if the part exceeds the 168-hour floor life limit.

Q: Does the MMPQ2907A support the full temperature range of the MPQ2907 PBFREE?

A: No. The MPQ2907 PBFREE operates from -65°C to 150°C, while the MMPQ2907A operates from -55°C to 150°C. Applications requiring operation below -55°C cannot use the MMPQ2907A. Alternative substitutes must be evaluated for such applications.

Q: Why does the MMPQ2907A have a higher DC current gain specification?

A: The MMPQ2907A specifies hFE (Min) of 100 @ 150mA, 10V, compared to the MPQ2907 PBFREE at 50 @ 300mA, 10V. These are measured at different collector current levels. The higher gain of the MMPQ2907A at lower collector current indicates improved transistor characteristics and does not create incompatibility with existing circuit designs.

Q: Is the MMPQ2907A suitable for new design implementations?

A: Yes. The MMPQ2907A is classified as Active product status with high inventory availability (138,763 pieces). It is the recommended choice for new designs requiring quad PNP transistor arrays with the specified electrical characteristics. The Surface Mount 16-SOIC package aligns with modern PCB manufacturing practices.

Q: What certifications apply to both parts?

A: Both the MPQ2907 PBFREE and MMPQ2907A are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Compliance requirements are satisfied by either part.
