MJE210 Equivalent & Substitute Parts

Part Overview

The MJE210 is a through-hole PNP bipolar junction transistor manufactured by onsemi, rated for 40 V collector-emitter breakdown voltage and 5 A maximum collector current. The device is packaged in TO-126 configuration and is designed for general-purpose switching and amplification applications requiring 15 W power dissipation capability.

The MJE210 carries an Obsolete product status, indicating it is no longer in active production. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJE210 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Transistor polarity: PNP
• Maximum collector current: 5 A
• Maximum collector-emitter breakdown voltage: 40 V
• Saturation voltage: 1.8 V @ 1A, 5A
• Collector cutoff current: 100 nA
• Minimum DC current gain: 45 @ 2A, 1V
• Maximum power dissipation: 15 W
• Transition frequency: 65 MHz
• Operating temperature range: -65°C to 150°C

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Package designation: TO-126-3

The MJE210G meets all specified electrical and mechanical parameters and is therefore a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MJE210G is a direct electrical and mechanical equivalent to the MJE210. All specified electrical parameters, including collector current rating, breakdown voltage, saturation characteristics, current gain, power dissipation, and frequency response, are identical. Physical packaging and mounting configuration are identical.

The MJE210G carries Last Time Buy product status, indicating limited future availability. The MJE210G is ROHS3 compliant, whereas the original MJE210 is non-compliant. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

For new designs and production applications, the MJE210G is the appropriate selection. Existing inventory of MJE210 units may be used interchangeably with MJE210G in applications where RoHS compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can MJE210G be used as a direct replacement for MJE210 in existing designs?

A: Yes. The MJE210G is electrically and mechanically identical to the MJE210. All electrical parameters, including current rating, voltage rating, gain characteristics, and frequency response, are equivalent. The TO-126-3 package is identical, allowing direct substitution in through-hole PCB layouts without modification.

Q: What is the difference between MJE210 and MJE210G?

A: The primary differences are product status and regulatory compliance. The MJE210 is Obsolete and RoHS non-compliant. The MJE210G is Last Time Buy status and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Is the MJE210G available in the same package as the MJE210?

A: Yes. Both parts use the TO-126-3 package configuration for through-hole mounting. Physical dimensions and pin configuration are identical, enabling direct PCB substitution.

Q: What does Last Time Buy status mean for the MJE210G?

A: Last Time Buy indicates the manufacturer has announced end-of-life for this part number. Production will cease after a specified date, and no further manufacturing runs are planned. Existing inventory is available for purchase, but long-term availability cannot be guaranteed.

Q: Are there any compliance differences between MJE210 and MJE210G?

A: Yes. The MJE210G is ROHS3 compliant, while the MJE210 is RoHS non-compliant. Both parts are REACH Unaffected. For applications requiring RoHS compliance, the MJE210G must be used.

Q: Can MJE210 and MJE210G be mixed in the same production batch?

A: Yes. Since electrical and mechanical parameters are identical, both parts can be used interchangeably in the same circuit design and PCB layout. However, RoHS compliance status should be considered for end-product certification requirements.
