Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMSZ4707-TP is determined by the following critical parameters:

• Zener Voltage (Vz): 20 V nominal with ±5% tolerance
• Power Dissipation: 500 mW maximum
• Package Type: SOD-123 surface mount
• Reverse Leakage Current: 10 nA @ 15.2 V
• Operating Temperature Range: -55°C to 150°C
• Compliance: RoHS3 compliant, REACH unaffected

The substitute part MMSZ4707T1G, manufactured by onsemi, meets all critical electrical and mechanical parameters. Both parts share identical base product designation (MMSZ4707), voltage rating, power rating, package type, and compliance certifications. The forward voltage specification differs slightly (900 mV vs. 950 mV @ 10 mA), which remains within acceptable operational variance for Zener diode applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MMSZ4707-TP and MMSZ4707T1G are Active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than electrical performance differences. The MMSZ4707T1G (onsemi) offers higher inventory availability (20,400 pcs vs. 3,560 pcs), making it suitable for high-volume production requirements. Both parts are functionally equivalent for 20 V Zener diode applications requiring 500 mW power dissipation in SOD-123 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can MMSZ4707T1G replace MMSZ4707-TP in existing designs?

A: Yes. Both parts share identical Zener voltage (20 V), power rating (500 mW), package type (SOD-123), and operating temperature range (-55°C to 150°C). The forward voltage difference (900 mV vs. 950 mV @ 10 mA) is within normal Zener diode specification variance and does not affect substitution compatibility.

Q: Are there package compatibility concerns?

A: No. Both parts use SOD-123 surface mount packaging with identical mechanical dimensions and pin configuration. PCB layout and reflow soldering parameters remain unchanged.

Q: What compliance certifications apply to both parts?

A: Both MMSZ4707-TP and MMSZ4707T1G are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050.

Q: Is there a difference in moisture sensitivity?

A: No. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain availability and procurement lead times. Both parts are electrically and mechanically equivalent for 20 V Zener diode applications.
