S9014-C-BP Equivalent & Substitute Parts

Part Overview

The S9014-C-BP is a Bipolar (BJT) NPN transistor manufactured by Micro Commercial Co, rated for 45V collector-emitter breakdown voltage and 100mA maximum collector current. This device is packaged in a TO-92 through-hole configuration and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts with active availability are necessary for new designs and ongoing production requirements. The S9014-C-BP remains functionally viable for applications requiring low-power NPN switching and amplification in the specified voltage and current ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S9014-C-BP is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor type must be NPN
• Maximum collector current (Ic) must be equal to or greater than 100mA
• Collector-emitter breakdown voltage (Vce) must be equal to or greater than 45V
• Maximum power dissipation must be equal to or greater than 400mW
• Operating temperature range must encompass the required application range

Mechanical Equivalence Criteria:

• Package type must be TO-92-3 (TO-226-3) through-hole configuration
• Pin configuration must be compatible with TO-92 standard pinout

Compliance Criteria:

• RoHS compliance status must be maintained or upgraded
• ECCN and HTSUS classifications must remain consistent

The BC550CBU manufactured by onsemi meets all substitution criteria for the S9014-C-BP, providing equivalent or superior electrical performance within the same physical package.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The BC550CBU is a direct substitute for the S9014-C-BP in all applications where the S9014-C-BP was previously specified. The BC550CBU maintains electrical equivalence across all critical parameters while providing enhanced performance characteristics. The BC550CBU is manufactured by onsemi with active product status, ensuring long-term availability and supply chain continuity.

Compliance Considerations:

The BC550CBU carries ROHS3 compliance certification, which supersedes the RoHS compliance of the S9014-C-BP. Both devices maintain identical ECCN (EAR99) and HTSUS (8541.21.0075) classifications, ensuring regulatory consistency in procurement and export documentation.

Performance Enhancement:

The BC550CBU provides superior transition frequency (300MHz versus 150MHz) and increased maximum power dissipation (500mW versus 400mW). These enhancements do not introduce incompatibility with existing circuit designs and provide additional design margin for thermal and frequency-dependent applications.

Inventory and Availability:

The BC550CBU is available in active inventory (2860 Pcs New Original In Stock) with active product status, whereas the S9014-C-BP is classified as obsolete. Selection of the BC550CBU ensures component availability for current and future production requirements.

Frequently Asked Questions (FAQ)

Q: Can the BC550CBU be used as a direct pin-for-pin replacement for the S9014-C-BP?

A: Yes. Both devices use the TO-92-3 package with identical pinout configuration. The BC550CBU is a direct pin-for-pin substitute with no circuit modifications required.

Q: Are there electrical differences between the S9014-C-BP and BC550CBU that affect circuit operation?

A: Both devices meet the same maximum ratings for collector current (100mA) and collector-emitter breakdown voltage (45V). The BC550CBU provides higher transition frequency (300MHz versus 150MHz) and greater power dissipation capability (500mW versus 400mW). These differences represent performance enhancements that do not degrade compatibility with existing designs.

Q: What is the significance of the higher DC Current Gain (hFE) specification in the BC550CBU?

A: The BC550CBU specifies a minimum hFE of 420 @ 2mA, 5V, compared to the S9014-C-BP minimum of 200 @ 1mA, 5V. Higher current gain provides improved switching efficiency and reduced base drive requirements. This enhancement is compatible with all applications designed for the S9014-C-BP.

Q: Does the BC550CBU meet the same compliance requirements as the S9014-C-BP?

A: The BC550CBU meets or exceeds all compliance requirements. It carries ROHS3 certification (superior to RoHS compliance) and maintains identical ECCN and HTSUS classifications. REACH status is listed as unaffected, indicating full regulatory compliance.

Q: Are there any thermal considerations when substituting the BC550CBU for the S9014-C-BP?

A: The BC550CBU supports the same maximum operating temperature (150°C) as the S9014-C-BP. The increased power dissipation rating (500mW versus 400mW) provides additional thermal margin in power-limited applications.

Q: What is the moisture sensitivity level (MSL) of the BC550CBU?

A: The BC550CBU is listed as Not Applicable for moisture sensitivity level, indicating it does not require moisture-controlled storage or handling procedures. This represents a simplification compared to the S9014-C-BP MSL rating of 1 (Unlimited).

Q: Is the BC550CBU available in the same packaging options as the S9014-C-BP?

A: Both devices are supplied in TO-92-3 through-hole packages. The BC550CBU is available in bulk packaging, consistent with standard component procurement practices for active production items.
