MPS6652RLRA Equivalent & Substitute Parts

Part Overview

The MPS6652RLRA is a PNP bipolar junction transistor manufactured by onsemi, rated for 40 V collector-emitter breakdown voltage and 1 A maximum collector current. This device is packaged in TO-92 (TO-226-3) through-hole configuration and is designed for general-purpose switching and amplification applications. The MPS6652RLRA is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the through-hole TO-92 package format.

Substitute Part Grouping Explanation

Substitution of the MPS6652RLRA is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Criteria:

Transistor Type: PNP (mandatory match)
Voltage - Collector Emitter Breakdown (Max): 40 V (minimum requirement)
Power - Max: 625 mW (minimum requirement)
Operating Temperature Range: -55°C to 150°C (mandatory match)
Mounting Type: Through Hole (mandatory match)
Package / Case: TO-92-3 or TO-226-3 (mandatory match)

Allowable Parameter Variations:

Current - Collector (Ic) (Max): Substitute parts may have lower maximum ratings (200 mA, 600 mA) provided the application does not require the full 1 A capability
Frequency - Transition: Substitute parts may have higher frequency ratings (250 MHz, 200 MHz) without affecting compatibility
DC Current Gain (hFE): Variations are acceptable within the specified operating conditions

Substitute parts are grouped into two categories based on maximum collector current capability: 200 mA devices (2N3906 series) and 600 mA devices (2N4403 series). Both categories maintain the 40 V voltage rating, 625 mW power dissipation, and TO-92-3 package format required for direct substitution.

Engineering Selection Recommendations

Product Status Consideration: The MPS6652RLRA is classified as obsolete. All listed substitute parts are active products with ongoing manufacturing support. Selection of an active substitute part ensures long-term component availability and supply chain continuity.

Compliance Status: The MPS6652RLRA is RoHS non-compliant. Substitute parts 2N3906TAR, 2N3906TF, 2N3906TFR, 2N4403TA, 2N4403TAR, 2N4403TF, and 2N4403TFR are ROHS3 compliant. For applications requiring RoHS compliance, selection of compliant substitute parts is necessary. The 2N3906TA (Fairchild Semiconductor) does not specify RoHS status.

Current Rating Selection:

For applications requiring maximum collector current up to 200 mA, the 2N3906 series (2N3906TA, 2N3906TAR, 2N3906TF, 2N3906TFR) provides direct electrical substitution with higher transition frequency (250 MHz).
For applications requiring collector current between 200 mA and 600 mA, the 2N4403 series (2N4403TA, 2N4403TAR, 2N4403TF, 2N4403TFR) provides direct electrical substitution with 200 MHz transition frequency.
For applications requiring collector current above 600 mA, no substitute part from the provided list maintains full 1 A capability.

Packaging and Inventory: All substitute parts are available in TO-92-3 through-hole package format. Inventory availability varies: 2N4403TA (60,100 pcs), 2N4403TAR (20,400 pcs), 2N3906TA (32,320 pcs), 2N3906TAR (9,200 pcs), 2N4403TFR (2,300 pcs), 2N4403TF (1,500 pcs), 2N3906TF (1,300 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 2N3906 series replace the MPS6652RLRA in all applications?

A: The 2N3906 series can replace the MPS6652RLRA only in applications where the maximum collector current requirement does not exceed 200 mA. The 2N3906 series is rated for 200 mA maximum collector current, compared to the MPS6652RLRA's 1 A rating. All other electrical parameters (40 V breakdown voltage, 625 mW power dissipation, -55°C to 150°C operating range) are maintained. The 2N3906 series provides higher transition frequency (250 MHz vs. 100 MHz).

Q: Can the 2N4403 series replace the MPS6652RLRA in all applications?

A: The 2N4403 series can replace the MPS6652RLRA only in applications where the maximum collector current requirement does not exceed 600 mA. The 2N4403 series is rated for 600 mA maximum collector current. All other electrical parameters (40 V breakdown voltage, 625 mW power dissipation, -55°C to 150°C operating range) are maintained. The 2N4403 series provides 200 MHz transition frequency.

Q: What is the difference between the packaging designations (TA, TAR, TF, TFR) for the 2N3906 and 2N4403 series?

A: The packaging designations indicate different tape and reel configurations for automated assembly. TA and TAR designations indicate Cut Tape (CT) packaging. TF and TFR designations also indicate Cut Tape (CT) packaging. These designations do not affect electrical performance or physical package dimensions. All variants use the TO-92-3 through-hole package format.

Q: Are all substitute parts RoHS compliant?

A: The 2N3906TA (Fairchild Semiconductor) does not specify RoHS status. All onsemi substitute parts (2N3906TAR, 2N3906TF, 2N3906TFR, 2N4403TA, 2N4403TAR, 2N4403TF, 2N4403TFR) are ROHS3 compliant. The original MPS6652RLRA is RoHS non-compliant.

Q: Can substitute parts be used interchangeably on the same PCB?

A: Yes, all substitute parts use the TO-92-3 through-hole package format with identical pin configuration (PNP transistor: Base, Collector, Emitter). Physical board layout compatibility is maintained. However, circuit design must account for the specific maximum collector current rating of the selected substitute part.

Q: What is the impact of higher transition frequency in the 2N3906 series?

A: The 2N3906 series provides 250 MHz transition frequency compared to the MPS6652RLRA's 100 MHz. Higher transition frequency indicates faster switching capability and improved high-frequency performance. This characteristic does not negatively affect applications designed for lower frequencies; it represents an enhancement in performance capability.

Q: Which substitute part should be selected for new designs?

A: For new designs, selection should be based on application current requirements and compliance needs. If maximum collector current does not exceed 200 mA and RoHS compliance is required, select from the 2N3906 series (2N3906TAR, 2N3906TF, or 2N3906TFR). If maximum collector current does not exceed 600 mA and RoHS compliance is required, select from the 2N4403 series (2N4403TA, 2N4403TAR, 2N4403TF, or 2N4403TFR). All selected parts are active products with ongoing manufacturing support.
