Engineering Selection Recommendations

The MMSZ5267BT1G is a direct electrical and mechanical equivalent to the MMSZ5267B-TP. Both components are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Selection between these parts should be based on:

Packaging Format Availability: The MMSZ5267B-TP is supplied in Tape & Reel format, while the MMSZ5267BT1G is available in Cut Tape and Digi-Reel® formats. Manufacturing and assembly processes may have specific packaging requirements that determine which format is appropriate for production workflows.

Inventory and Lead Time: The MMSZ5267BT1G has significantly higher inventory availability (155,100 pieces) compared to the MMSZ5267B-TP (919 pieces), which may influence supply chain decisions for high-volume applications.

Regulatory Compliance: Both parts maintain identical compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN classification, and HTSUS code 8541.10.0050), ensuring no regulatory barriers to substitution.

Frequently Asked Questions (FAQ)

Q: Can the MMSZ5267BT1G replace the MMSZ5267B-TP in existing designs?

A: Yes. The MMSZ5267BT1G is electrically and mechanically equivalent across all specified parameters including zener voltage, power rating, impedance, leakage current, temperature range, and SOD-123 package dimensions. The only difference is the packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling, storage, and automated assembly processes. Tape & Reel format is typically used for high-speed pick-and-place assembly, while Cut Tape and Digi-Reel® formats serve different manufacturing workflows. The electrical performance of the component is unaffected by packaging format.

Q: Are there any temperature or environmental limitations that differ between these parts?

A: No. Both the MMSZ5267B-TP and MMSZ5267BT1G operate across the identical temperature range of -55°C to 150°C and share the same moisture sensitivity level of 1 (Unlimited), indicating no special storage or handling requirements.

Q: Do these parts have different regulatory compliance status?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS code (8541.10.0050). They meet identical regulatory requirements for use in electronic equipment.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are zener voltage (75 V nominal with ±5% tolerance), maximum power dissipation (500 mW), maximum impedance (270 Ohms), and reverse leakage current (100 nA @ 56 V). All these parameters are identical between the MMSZ5267B-TP and MMSZ5267BT1G.
