MPS6602G Equivalent & Substitute Parts

Part Overview

The MPS6602G is an NPN bipolar junction transistor manufactured by onsemi, rated for 40 V collector-emitter breakdown voltage and 1 A maximum collector current in a Through Hole TO-92 package. This device is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The MPS6602G serves general-purpose switching and amplification applications requiring moderate voltage and current ratings with compact form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS6602G is determined by equivalence in the following critical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN (required match)
• Current - Collector (Ic) Max: 1 A (required match or higher)
• Voltage - Collector Emitter Breakdown: Minimum 40 V (equal or higher acceptable)
• Power Dissipation: Minimum 625 mW (equal or higher acceptable)
• Frequency - Transition: Minimum 100 MHz (equal or higher acceptable)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required match)
• Package Compatibility: TO-92 or TO-92 compatible form factor (required match)

The substitute parts ZTX450 and ZTX450STZ meet all electrical and mechanical compatibility requirements. Both devices exceed the MPS6602G specifications in voltage rating (45 V vs. 40 V), power dissipation (1 W vs. 625 mW), and transition frequency (150 MHz vs. 100 MHz). Both maintain identical collector current rating (1 A) and Through Hole mounting configuration with TO-92 compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

ZTX450 (Diodes Incorporated) - Bulk Packaging

The ZTX450 is an active product with full RoHS3 compliance and REACH unaffected status. This device provides electrical performance exceeding MPS6602G specifications across all rated parameters. The higher voltage rating (45 V), increased power dissipation capability (1 W), and superior transition frequency (150 MHz) establish margin for circuit design. The E-Line-3 package maintains mechanical compatibility with TO-92 form factor. Selection of ZTX450 is appropriate for applications requiring standard bulk component procurement with active manufacturer support.

ZTX450STZ (Diodes Incorporated) - Cut Tape Packaging

The ZTX450STZ is an active product with RoHS3 compliance and REACH unaffected status, supplied in Cut Tape (CT) packaging format. Electrical specifications are identical to ZTX450. This variant is suitable for automated assembly processes and tape-and-reel component handling. Operating temperature range is not specified for this variant; applications requiring confirmed temperature performance should reference ZTX450 documentation.

Both substitute parts satisfy the electrical and mechanical requirements for MPS6602G replacement. Selection between ZTX450 and ZTX450STZ depends on procurement format requirements and assembly methodology rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can ZTX450 or ZTX450STZ directly replace MPS6602G in existing circuit boards?

A: Yes. Both substitute parts maintain identical collector current rating (1 A), NPN transistor type, and Through Hole TO-92 compatible package configuration. The higher voltage rating (45 V vs. 40 V) and increased power dissipation (1 W vs. 625 mW) provide design margin. Pin configuration and mechanical form factor are compatible with existing PCB layouts designed for MPS6602G.

Q: What is the difference between ZTX450 and ZTX450STZ?

A: ZTX450 and ZTX450STZ are electrically identical devices with identical electrical specifications. The primary difference is packaging format: ZTX450 is supplied in Bulk packaging, while ZTX450STZ is supplied in Cut Tape (CT) format. Selection depends on procurement and assembly requirements. ZTX450STZ is optimized for automated tape-and-reel handling.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ZTX450 and ZTX450STZ are RoHS3 compliant. The original MPS6602G RoHS status is not specified in available documentation.

Q: What is the operating temperature range for ZTX450STZ?

A: Operating temperature range is not specified for ZTX450STZ in the provided data. ZTX450 specifies -55°C to 200°C, which exceeds the MPS6602G range of -55°C to 150°C. For applications requiring confirmed temperature performance specifications, ZTX450 documentation should be referenced.

Q: Do the substitute parts have the same saturation voltage characteristics?

A: No. ZTX450 and ZTX450STZ specify lower saturation voltage (250 mV @ 15 mA, 150 mA) compared to MPS6602G (600 mV @ 100 mA, 1 A). Lower saturation voltage indicates improved switching efficiency and reduced power dissipation during saturation. This represents an improvement over the original device for switching applications.

Q: Are moisture sensitivity levels equivalent?

A: Yes. All three devices specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: What is the inventory status for substitute parts?

A: ZTX450 has 1600 pieces in stock. ZTX450STZ has 15901 pieces in stock. Both are active products with established supply availability.
