Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS751RLRAG is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 2 A
• Voltage - Collector Emitter Breakdown (Max): 60 V
• Vce Saturation (Max) @ Ib, Ic: 500mV @ 200mA, 2A
• Current - Collector Cutoff (Max): 100nA (ICBO)
• Power - Max: 625 mW
• Frequency - Transition: 75MHz

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-226-3, TO-92-3

Acceptable Variations:

• DC Current Gain (hFE) (Min) @ Ic, Vce: Minimum specification may vary
• Operating Temperature: Upper limit may be reduced to 150°C (TJ)
• Product Status: Active substitutes are preferred over obsolete parts
• Packaging Format: Cut Tape (CT) is acceptable for through-hole components

Parameter Comparison

Engineering Selection Recommendations

MPS751 (Fairchild Semiconductor): This part is a direct electrical equivalent with active product status. All critical electrical parameters match the MPS751RLRAG specification. The part is available in TO-92-3 packaging, which is mechanically compatible with the original design. Selection of this substitute is appropriate for applications requiring active component availability and ongoing manufacturer support.

MPS751-D26Z (onsemi): This part is an active onsemi product offering electrical equivalence with the MPS751RLRAG. The DC Current Gain specification differs (40 @ 2A, 2V versus 75 @ 1A, 2V), reflecting measurement at different operating points. All other electrical parameters remain equivalent. The part is supplied in Cut Tape (CT) packaging format and carries RoHS3 compliance certification. This substitute is suitable for applications where onsemi product continuity is preferred and the alternative hFE specification is acceptable for the circuit design.

Both substitutes maintain compliance with REACH and EAR99 export control classifications. Selection between these options depends on manufacturer preference, supply chain considerations, and specific circuit requirements regarding DC current gain specifications.

Frequently Asked Questions (FAQ)

Q: Can MPS751 (Fairchild) be used as a direct replacement for MPS751RLRAG?

A: Yes. The MPS751 from Fairchild Semiconductor meets all electrical and mechanical parameter requirements for direct substitution. Both devices are PNP transistors with identical maximum ratings for collector current (2A), collector-emitter breakdown voltage (60V), saturation voltage, power dissipation (625mW), and transition frequency (75MHz). Both use TO-92-3 through-hole packaging.

Q: What is the difference between MPS751 and MPS751-D26Z?

A: Both parts are electrically equivalent PNP transistors with identical maximum ratings. The primary difference is the DC Current Gain (hFE) specification: MPS751 specifies 75 @ 1A, 2V, while MPS751-D26Z specifies 40 @ 2A, 2V. These measurements occur at different operating points. MPS751-D26Z is supplied in Cut Tape (CT) packaging and carries RoHS3 compliance, whereas MPS751 specifications do not include this certification detail.

Q: Are the TO-92-3 and TO-226-3 packages interchangeable?

A: TO-92-3 and TO-226-3 refer to the same physical package designation. Both terms describe the three-lead through-hole transistor package used for these devices. The packages are mechanically and electrically interchangeable in PCB designs.

Q: Why is the MPS751RLRAG classified as obsolete?

A: The MPS751RLRAG is listed as obsolete by the manufacturer. Active substitutes (MPS751 and MPS751-D26Z) are available with identical electrical specifications and current production status, making them appropriate alternatives for new designs and ongoing procurement.

Q: Can I use MPS751-D26Z in applications requiring the original hFE specification of 75?

A: The MPS751-D26Z specifies a minimum hFE of 40 @ 2A, 2V, which differs from the original 75 @ 1A, 2V specification. Circuit compatibility depends on the specific application requirements. If the circuit design requires hFE ≥ 75 at the specified operating point, the MPS751-D26Z may not be suitable. The MPS751 (Fairchild) maintains the original hFE specification of 75 @ 1A, 2V.

Q: What compliance certifications apply to these substitute parts?

A: All three parts (MPS751RLRAG, MPS751, and MPS751-D26Z) carry EAR99 export control classification and REACH Unaffected status. MPS751-D26Z additionally carries RoHS3 compliance certification. These certifications confirm regulatory compliance for distribution and use in applicable markets.
