Key Parameters

Substitute Part Grouping Explanation

Substitution of the CP188-BC107A-CT is determined by electrical and mechanical parameter equivalence within the bipolar junction transistor category. The following parameters establish substitution eligibility:

Electrical Parameters (Must Match):

• Collector current rating: 200 mA maximum
• Collector-emitter breakdown voltage: 45 V maximum
• Vce saturation characteristics: 600 mV @ 5 mA, 100 mA
• Collector cutoff current: 15 nA maximum
• DC current gain (hFE): 110 minimum @ 2 mA, 5 V
• Power dissipation: 600 mW maximum

Mechanical Parameters (Must Match):

• Mounting type: Surface mount
• Package type: Die

Compliance Parameters:

• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Product status (active versus obsolete) does not affect substitution eligibility but influences availability and long-term supply considerations.

Parameter Comparison

Engineering Selection Recommendations

The CP388X-BC107A-CT is a direct electrical and mechanical equivalent to the CP188-BC107A-CT. All critical electrical parameters, including collector current, breakdown voltage, saturation characteristics, current gain, and power dissipation, are identical. Both components share identical mechanical specifications (surface mount die package) and comply with RoHS3 requirements.

The primary distinction between these parts is product status: the CP188-BC107A-CT is classified as obsolete, while the CP388X-BC107A-CT is active. For applications requiring long-term component availability and supply chain continuity, the CP388X-BC107A-CT is the appropriate selection. Both components maintain identical moisture sensitivity levels and thermal operating ranges.

Current inventory levels indicate 1055 units of the CP388X-BC107A-CT are available, compared to 827 units of the CP188-BC107A-CT. Selection should prioritize the active product status of the CP388X-BC107A-CT for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the CP388X-BC107A-CT replace the CP188-BC107A-CT in existing applications?

A: Yes. The CP388X-BC107A-CT is electrically and mechanically equivalent. All electrical parameters (collector current, breakdown voltage, saturation voltage, current gain, and power dissipation) are identical. Both components use identical surface mount die packaging and comply with RoHS3 standards.

Q: What is the significance of the product status difference (obsolete versus active)?

A: Product status indicates the manufacturer's support and availability timeline. The CP188-BC107A-CT is obsolete, meaning the manufacturer has discontinued active production. The CP388X-BC107A-CT is active, indicating ongoing manufacturing support and long-term availability. For new designs and sustained production, the active part is preferred.

Q: Are there any thermal or operating condition differences between these parts?

A: No. Both components operate across the identical temperature range (-65°C to +200°C junction temperature) and maintain identical power dissipation limits (600 mW maximum). Thermal performance characteristics are equivalent.

Q: Do these parts require different handling or storage procedures?

A: No. Both components share identical moisture sensitivity levels (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Storage and handling procedures are identical.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both components are surface mount die packages with identical electrical and mechanical specifications. PCB layout, assembly procedures, and reflow profiles remain unchanged when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both the CP188-BC107A-CT and CP388X-BC107A-CT are RoHS3 compliant and carry ECCN classification EAR99. Compliance documentation is equivalent for both components.
