Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMSZ5247B-TP are identified based on strict alignment with the following critical parameters:

Electrical Compatibility Criteria:

• Power dissipation rating: 500 mW maximum
• Tolerance: ±5%
• Operating temperature range: -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type: SOD-123 surface mount
• Mounting configuration: Surface mount

Regulatory & Compliance Criteria:

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

The MMSZ5247BT1G manufactured by onsemi qualifies as a direct substitute based on matching all electrical power specifications, tolerance requirements, operating temperature range, and mechanical package configuration. Both components are active products with identical RoHS3 compliance and MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the MMSZ5247B-TP and MMSZ5247BT1G are active products with full regulatory compliance. Selection between these components is based on availability, packaging format, and supply chain requirements rather than electrical or mechanical differences.

The MMSZ5247BT1G is supplied in Tape & Reel (TR) packaging format, which is suitable for high-volume automated assembly operations. The MMSZ5247B-TP packaging format is not specified in the provided data.

Both components maintain identical electrical performance specifications, temperature operating range, and compliance certifications. Component selection should be determined by procurement availability, production volume requirements, and existing supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can the MMSZ5247BT1G replace the MMSZ5247B-TP in existing designs?

A: Yes. Both components share identical electrical specifications (500 mW power rating, ±5% tolerance, -55°C to 150°C operating range), mechanical package configuration (SOD-123 surface mount), and regulatory compliance status (RoHS3, MSL 1). Direct substitution is supported at the circuit level.

Q: What is the primary difference between these two parts?

A: The primary difference is the packaging format. The MMSZ5247BT1G is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly. The MMSZ5247B-TP packaging format is not specified in the available data.

Q: Are there any temperature or power rating differences?

A: No. Both components operate across the identical temperature range (-55°C to 150°C) and share the same maximum power dissipation rating of 500 mW.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MMSZ5247B-TP and MMSZ5247BT1G are RoHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity). Both are classified as active products.

Q: Which part should be selected for new designs?

A: Selection should be based on current availability, production volume, and supply chain strategy. Both components are functionally equivalent and support identical circuit applications.
