S8050-C-BP Equivalent & Substitute Parts

Part Overview

The S8050-C-BP is a Bipolar (BJT) NPN transistor manufactured by Micro Commercial Co, rated for 25V collector-emitter breakdown voltage and 500mA maximum collector current. This device is classified as Obsolete, indicating discontinued production and limited availability for new designs. The part operates in the Through Hole TO-92 package and is suitable for general-purpose switching and amplification applications requiring moderate current and voltage ratings.

Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for design continuity, procurement reliability, and long-term supply chain management. Substitute parts must maintain electrical compatibility across critical parameters while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility for the S8050-C-BP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor Type: NPN (polarity and conduction mechanism must be identical)
• Current - Collector (Ic) Max: 500 mA (maximum current handling capability)
• Voltage - Collector Emitter Breakdown (Max): 25 V (maximum voltage rating)
• Power - Max: 625 mW (thermal dissipation limit)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: TO-92-3 (physical and electrical interface compatibility)

The MPS3415 TIN/LEAD meets all mandatory matching criteria. Both parts are NPN transistors with identical maximum collector current (500 mA), collector-emitter breakdown voltage (25 V), and maximum power dissipation (625 mW). Both use Through Hole mounting in the TO-92-3 package, ensuring direct physical and electrical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The MPS3415 TIN/LEAD is electrically and mechanically equivalent to the S8050-C-BP across all critical parameters. Both parts share identical maximum ratings for collector current, collector-emitter breakdown voltage, and power dissipation. The MPS3415 operates across a wider temperature range (-65°C to 150°C versus -55°C to 150°C), providing enhanced low-temperature performance.

Product Status Consideration:

The S8050-C-BP is classified as Obsolete, while the MPS3415 TIN/LEAD maintains Active product status. This distinction is significant for long-term supply chain planning. Active status indicates ongoing manufacturing, documented availability, and manufacturer support. Transition to the MPS3415 TIN/LEAD is recommended for new designs and production continuity.

Compliance Differences:

The S8050-C-BP is RoHS Compliant; the MPS3415 TIN/LEAD is RoHS Non-compliant. This difference reflects the lead-based solder finish (TIN/LEAD) used in the MPS3415. Design teams operating under RoHS-restricted environments must evaluate regulatory requirements before substitution. The MPS3415 is REACH Unaffected, indicating no REACH substance of concern restrictions.

Inventory and Availability:

Current inventory shows 919 units of S8050-C-BP and 872 units of MPS3415 TIN/LEAD in stock. The MPS3415 represents a viable alternative for immediate procurement needs and future supply security.

Frequently Asked Questions (FAQ)

Q: Can the MPS3415 TIN/LEAD be used as a direct replacement for the S8050-C-BP in existing circuits?

A: Yes. Both parts are NPN transistors with identical maximum collector current (500 mA), collector-emitter breakdown voltage (25 V), and power dissipation (625 mW). Both use the TO-92-3 package with Through Hole mounting. Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What is the significance of the "Obsolete" status of the S8050-C-BP?

A: Obsolete status indicates that the manufacturer has discontinued production. This creates supply chain risk for long-term projects. The MPS3415 TIN/LEAD, with Active status, ensures ongoing availability and manufacturer support for future procurement cycles.

Q: Does the wider operating temperature range of the MPS3415 (-65°C to 150°C) provide any advantage?

A: The MPS3415 operates at -65°C minimum versus -55°C for the S8050-C-BP, extending the lower temperature limit by 10°C. This is relevant only if the application requires operation below -55°C. For standard temperature ranges, both parts are equivalent.

Q: What is the impact of RoHS compliance differences between these parts?

A: The S8050-C-BP is RoHS Compliant; the MPS3415 TIN/LEAD is RoHS Non-compliant due to its lead-based solder finish. Organizations subject to RoHS regulations (EU Directive 2011/65/EU) must verify regulatory applicability before selecting the MPS3415. Non-RoHS-restricted applications face no constraint.

Q: Are there differences in DC current gain (hFE) between these parts?

A: Yes. The S8050-C-BP specifies hFE (Min) of 120 @ 50mA, 1V. The MPS3415 specifies hFE (Min) of 180 @ 2mA, 4.5V. These measurements are taken at different operating points, making direct comparison inappropriate. Both parts meet their respective minimum gain specifications within their rated operating conditions.

Q: What packaging format is available for the MPS3415?

A: The MPS3415 TIN/LEAD is supplied in Bulk packaging. The S8050-C-BP packaging format is not specified in the provided data. Confirm packaging requirements with procurement specifications before ordering.

Q: Is the MPS3415 suitable for new product designs?

A: Yes. The MPS3415 TIN/LEAD is classified as Active, indicating current manufacturing and ongoing availability. It meets all electrical and mechanical requirements for applications previously designed around the S8050-C-BP. Verify RoHS compliance requirements for your specific application before design implementation.
