MMSZ4682-G3-08 Equivalent & Substitute Parts

Part Overview

The MMSZ4682-G3-08 is a surface mount Zener diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates at a nominal Zener voltage of 2.7 V with a maximum power dissipation of 500 mW in an SOD-123 package. The device is classified as Active and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range. Alternative sources become necessary due to inventory availability, supply chain optimization, or design flexibility requirements while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage nominal value: 2.7 V
• Package type: SOD-123 surface mount
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1

Secondary Compatibility Parameters:

• Maximum power dissipation: 500 mW (primary specification)
• Voltage tolerance: ±5% to ±7% (acceptable variance)
• Operating temperature range: -55°C to -65°C minimum; 150°C maximum
• Reverse leakage current: specification dependent

Parts are grouped as direct substitutes when all primary criteria are met. Parts with reduced power ratings (200 mW) or modified tolerance specifications (±7%) are classified as functional alternatives with application-dependent suitability.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Full Electrical & Mechanical Equivalence):

DDZ9682-7 (Diodes Incorporated) and MMSZ2V7T1G (onsemi) are direct substitutes for the MMSZ4682-G3-08. Both maintain identical nominal Zener voltage (2.7 V), ±5% tolerance, 500 mW power rating, and SOD-123 package specifications. All three parts carry Active product status and ROHS3 compliance with MSL 1 rating. The DDZ9682-7 extends the minimum operating temperature to -65°C, providing enhanced low-temperature performance.

Functional Alternatives (Application-Dependent):

MMSZ5223BT1G (onsemi) operates at 2.7 V nominal with 500 mW power rating and ±5% tolerance, maintaining full compatibility with the primary electrical specification. This part is suitable for applications where the specified reverse leakage current tolerance (75 µA @ 1 V) is acceptable.

BZT52C2V7-TP (Micro Commercial Co) provides 2.7 V Zener voltage in SOD-123 package with ROHS3 compliance. This part operates at reduced maximum power dissipation (200 mW) and ±7% tolerance. Selection of this part requires verification that the application power budget does not exceed 200 mW and that ±7% voltage tolerance is within circuit design margins.

Compliance & Certification Status:

All identified substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. All parts are classified as Active products with current manufacturing status. No regulatory or environmental compliance barriers exist for cross-substitution within this group.

Frequently Asked Questions (FAQ)

Q: Can MMSZ5223BT1G replace MMSZ4682-G3-08 in all applications?

A: MMSZ5223BT1G maintains the same 2.7 V nominal voltage, ±5% tolerance, 500 mW power rating, and SOD-123 package as the MMSZ4682-G3-08. The primary difference is reverse leakage current specification (75 µA @ 1 V versus 1 µA @ 1 V). Substitution is valid when circuit design does not require the lower leakage specification of the original part.

Q: Is BZT52C2V7-TP a suitable replacement for the MMSZ4682-G3-08?

A: BZT52C2V7-TP operates at 2.7 V nominal voltage in SOD-123 package with ROHS3 compliance. However, this part has a maximum power rating of 200 mW compared to 500 mW for the MMSZ4682-G3-08, and tolerance is ±7% versus ±5%. Substitution is valid only when the application power dissipation does not exceed 200 mW and ±7% voltage tolerance is acceptable for circuit operation.

Q: What is the difference between DDZ9682-7 and MMSZ4682-G3-08?

A: Both parts are 2.7 V, 500 mW Zener diodes in SOD-123 packages with ±5% tolerance and ROHS3 compliance. The DDZ9682-7 (Diodes Incorporated) extends the minimum operating temperature to -65°C compared to -55°C for the MMSZ4682-G3-08 (Vishay). Both parts are direct electrical and mechanical equivalents.

Q: Are all substitute parts available in the same packaging format?

A: MMSZ4682-G3-08, DDZ9682-7, and BZT52C2V7-TP are supplied in Tape & Reel (TR) packaging. MMSZ2V7T1G and MMSZ5223BT1G are supplied in Cut Tape (CT) & Digi-Reel® packaging. All parts use identical SOD-123 component packages suitable for surface mount assembly. Packaging format differences do not affect component-level compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Zener voltage nominal value of 2.7 V, (2) SOD-123 surface mount package, (3) ROHS3 compliance status, and (4) MSL 1 moisture sensitivity rating. Secondary parameters including power rating, voltage tolerance, operating temperature range, and reverse leakage current determine application-specific suitability.

Q: Can MMSZ2V7T1G be used as a direct replacement for MMSZ4682-G3-08?

A: Yes. MMSZ2V7T1G is a direct substitute. Both parts operate at 2.7 V nominal voltage with ±5% tolerance, 500 mW maximum power dissipation, and SOD-123 package. Both maintain ROHS3 compliance and MSL 1 rating. Operating temperature ranges are -55°C to 150°C for both parts.
