MMSZ4698-TP Equivalent & Substitute Parts

Part Overview

The MMSZ4698-TP is a Zener diode rated at 11 V nominal voltage with 500 mW maximum power dissipation in a surface mount SOD-123 package. Manufactured by Micro Commercial Co, this component is designed for voltage regulation and protection applications in electronic circuits. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package type and functional category. This ensures direct replacement capability in circuit designs without redesign requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the MMSZ4698-TP is determined by strict equivalence across the following critical parameters:

Zener Voltage (Vz): 11 V nominal with ±5% tolerance
Power Dissipation: 500 mW maximum
Package Type: SOD-123 surface mount
Reverse Leakage Current: 50 nA @ 8.4 V
Operating Temperature Range: -55°C to 150°C
Compliance Standards: RoHS3 compliant, REACH unaffected

Substitute parts must match all electrical specifications and maintain identical package geometry to ensure direct PCB compatibility without layout modifications. Forward voltage characteristics may vary within acceptable limits for the application category.

Engineering Selection Recommendations

The MMSZ4698T1G manufactured by onsemi is a direct functional equivalent to the MMSZ4698-TP. Both components share identical zener voltage specifications, power ratings, package geometry, and compliance certifications. The forward voltage differential (950 mV versus 900 mV at 10 mA) represents a minor variation within acceptable operating margins for zener diode applications and does not affect substitution eligibility.

Selection between these parts should be based on:

Availability: MMSZ4698T1G maintains higher inventory levels (41,300 pcs vs. 3,112 pcs)
Supply Chain Requirements: Both parts carry Active product status with equivalent lead times
Compliance Verification: Both maintain RoHS3 compliance and REACH unaffected status
Packaging Format: Both are supplied in Tape & Reel format suitable for automated assembly

No design modifications, circuit recalculation, or thermal analysis changes are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can MMSZ4698T1G replace MMSZ4698-TP in existing designs without PCB layout changes?

A: Yes. Both components use identical SOD-123 package geometry with matching pin configurations and footprint requirements. Direct substitution on existing PCBs is supported without layout modifications.

Q: What is the significance of the forward voltage difference between the two parts?

A: The forward voltage specification (950 mV vs. 900 mV @ 10 mA) reflects normal manufacturing variation within the zener diode product category. This 50 mV difference does not impact zener regulation performance or circuit functionality in standard applications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both MMSZ4698-TP and MMSZ4698T1G operate across the identical temperature range of -55°C to 150°C (TJ), supporting applications requiring extended thermal performance.

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

A: No. Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control measures are required during storage or handling.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain RoHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications.

Q: Can these parts be used interchangeably in automated assembly processes?

A: Yes. Both components are supplied in Tape & Reel packaging format compatible with standard pick-and-place equipment and reflow soldering processes.
