ZMC10 Equivalent & Substitute Parts

Part Overview

The ZMC10 is a Zener diode manufactured by Diotec Semiconductor, classified as a surface mount component in the DO-213AC (MINI-MELF, SOD-80) package. This device is rated for 10 V nominal Zener voltage with 500 mW maximum power dissipation and ±5% tolerance. The component is Active in product status and ROHS3 compliant. Substitute parts are identified to address inventory availability, packaging format preferences, or tolerance requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the ZMC10 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Voltage - Zener (Nom) (Vz): 10 V (exact match required)
Power - Max: 500 mW (exact match required)
Impedance (Max) (Zzt): 15 Ohms (exact match required)
Current - Reverse Leakage @ Vr: 100 nA @ 7 V (exact match required)
Operating Temperature: -50°C ~ 175°C (TJ) (exact match required)

Mechanical Equivalence Criteria:

Mounting Type: Surface Mount (exact match required)
Package / Case: DO-213AC, MINI-MELF, SOD-80 (exact match required)
Supplier Device Package: SOD-80C (exact match required)

Tolerance Variation: Tolerance specifications may vary (±5% or ±2%) without affecting substitution eligibility, as tolerance represents manufacturing precision rather than functional capability. All substitute parts maintain the same nominal Zener voltage and power rating.

Engineering Selection Recommendations

All substitute parts (ZMM10, ZMM10B, ZMM10R13) are electrically and mechanically equivalent to the ZMC10 based on the provided parameters. Selection among these alternatives is determined by the following factors:

Packaging Format:

ZMC10: Supplied in standard packaging format
ZMM10: Available in Cut Tape (CT) & Digi-Reel® format
ZMM10B: Available in Strip format
ZMM10R13: Available in Strip format

Tolerance Specification:

ZMC10, ZMM10, ZMM10R13: ±5% tolerance
ZMM10B: ±2% tolerance (tighter tolerance specification)

Compliance Status:

ZMC10, ZMM10B, ZMM10R13: ROHS3 Compliant
ZMM10: RoHS status not applicable

Inventory Availability: All parts are Active in product status with current stock levels available.

Frequently Asked Questions (FAQ)

Q: Can ZMM10 be used as a direct replacement for ZMC10?

A: Yes. ZMM10 is electrically and mechanically equivalent to ZMC10. Both devices share identical Zener voltage (10 V), power rating (500 mW), impedance (15 Ohms), reverse leakage current (100 nA @ 7 V), operating temperature range (-50°C ~ 175°C), and package specification (SOD-80C). The primary difference is packaging format (Cut Tape & Digi-Reel® versus standard format).

Q: What is the difference between ZMM10B and ZMM10R13?

A: ZMM10B and ZMM10R13 are electrically equivalent with identical Zener voltage, power rating, impedance, and leakage specifications. The distinction is tolerance: ZMM10B specifies ±2% tolerance, while ZMM10R13 specifies ±5% tolerance. Both are supplied in Strip packaging format.

Q: Is the ±2% tolerance of ZMM10B compatible with ZMC10 applications?

A: Yes. ZMM10B maintains the same nominal Zener voltage (10 V) and all other electrical parameters as ZMC10. The ±2% tolerance represents tighter manufacturing precision and is compatible with any application designed for the ZMC10 (±5% tolerance).

Q: Are all substitute parts ROHS3 compliant?

A: ZMM10B and ZMM10R13 are ROHS3 compliant. ZMM10 has RoHS status listed as not applicable. ZMC10 is ROHS3 compliant.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts share identical mechanical specifications: Surface Mount mounting type, DO-213AC/MINI-MELF/SOD-80 package, and SOD-80C supplier device package. PCB footprints and assembly processes are identical.

Q: What factors should determine which substitute part to select?

A: Selection should be based on: (1) required packaging format (Cut Tape, Strip, or standard), (2) tolerance requirement (±2% or ±5%), (3) compliance certification needs (ROHS3), and (4) inventory availability for your supply chain.
