MPSA56RLRPG Equivalent & Substitute Parts

Part Overview

The MPSA56RLRPG is a PNP bipolar junction transistor manufactured by onsemi, rated for 80 V collector-emitter breakdown voltage and 500 mA maximum collector current. This device is packaged in a through-hole TO-92 (TO-226-3) configuration and is designed for general-purpose switching and amplification applications. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSA56RLRPG is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Transistor type must be PNP
• Collector current rating must be ≥ 500 mA
• Collector-emitter breakdown voltage must be ≥ 80 V
• Vce saturation must be ≤ 250 mV @ 10mA, 100mA
• DC current gain (hFE) must be ≥ 100 @ 100mA, 1V
• Transition frequency must be ≥ 50 MHz
• Operating temperature range must encompass -55°C to 150°C
• Power dissipation must be ≥ 625 mW

Mechanical Compatibility Considerations:

• Package type determines board-level integration method (through-hole versus surface mount)
• Lead configuration and footprint affect PCB layout and assembly process

Substitutes are grouped into two categories: direct equivalents (same package type) and functional equivalents (different package type with identical electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

MPSA56-AP (Micro Commercial Co): This part is a direct mechanical and electrical equivalent to the MPSA56RLRPG, maintaining identical TO-92 through-hole packaging and all electrical specifications. Both devices are classified as obsolete. The MPSA56-AP carries ROHS3 compliance certification, whereas the MPSA56RLRPG compliance status is not specified. Selection of MPSA56-AP is appropriate for applications requiring through-hole mounting and direct footprint compatibility with existing PCB designs. Inventory availability is limited (793 units).

MMBTA56LT1G (onsemi): This part provides electrical equivalence to the MPSA56RLRPG with identical electrical parameters across all critical specifications. The primary distinction is the package type: MMBTA56LT1G uses surface-mount SOT-23-3 (TO-236) packaging, whereas MPSA56RLRPG uses through-hole TO-92 packaging. Power dissipation rating is reduced to 225 mW compared to 625 mW for the through-hole variant. MMBTA56LT1G is classified as active product status and carries ROHS3 compliance certification. This substitute is suitable for new designs utilizing surface-mount assembly processes or for applications where board space is constrained. Inventory availability is significantly higher (416,100 units).

Both substitute parts maintain compliance with REACH regulations and possess unlimited moisture sensitivity level (MSL 1) ratings.

Frequently Asked Questions (FAQ)

Q: Can MPSA56-AP be used as a direct replacement for MPSA56RLRPG in existing through-hole designs?

A: Yes. MPSA56-AP is electrically and mechanically equivalent to MPSA56RLRPG. Both devices share identical electrical specifications (500 mA collector current, 80 V breakdown voltage, 625 mW power dissipation) and TO-92 through-hole packaging. No PCB layout modifications are required.

Q: What is the primary difference between MMBTA56LT1G and MPSA56RLRPG?

A: The primary difference is packaging. MMBTA56LT1G uses surface-mount SOT-23-3 (TO-236) packaging, while MPSA56RLRPG uses through-hole TO-92 (TO-226-3) packaging. All electrical parameters are identical except power dissipation: MMBTA56LT1G is rated for 225 mW versus 625 mW for MPSA56RLRPG. This difference reflects the thermal characteristics of the respective package types.

Q: Can MMBTA56LT1G be used in a through-hole application designed for MPSA56RLRPG?

A: No. MMBTA56LT1G is a surface-mount device and cannot be directly installed in through-hole PCB footprints. PCB redesign and assembly process modification would be required.

Q: Are all three parts RoHS compliant?

A: MPSA56-AP and MMBTA56LT1G are both ROHS3 compliant. The MPSA56RLRPG RoHS compliance status is not specified in the provided documentation.

Q: What is the product status of each part, and does this affect selection?

A: MPSA56RLRPG and MPSA56-AP are both classified as obsolete. MMBTA56LT1G is classified as active product. For new designs or long-term production requirements, MMBTA56LT1G is the preferred selection due to active status and higher inventory availability.

Q: Are there any electrical performance differences between the three parts?

A: All three parts are electrically equivalent across collector current (500 mA), breakdown voltage (80 V), saturation voltage (250 mV), current gain (100 minimum), transition frequency (50 MHz), and operating temperature range (-55°C to 150°C). Power dissipation differs only for MMBTA56LT1G (225 mW) due to package type, while MPSA56RLRPG and MPSA56-AP both support 625 mW.

Q: What inventory considerations should influence part selection?

A: MMBTA56LT1G has significantly higher inventory availability (416,100 units) compared to MPSA56-AP (793 units) and MPSA56RLRPG (4,300 units). For applications requiring sustained production or future restocking, MMBTA56LT1G availability provides supply chain advantages.
