Substitute Part Grouping Explanation

Substitution of the RY85_MBZ5240B is determined by functional equivalence in the zener diode category. The identified substitute, SZ2110.T, is classified as a Zener Diode and shares the same moisture sensitivity level (MSL 1). Both components are zener diodes designed for voltage regulation and protection applications.

The substitution logic is based on the following criteria:

• Component Category: Both parts are Zener Diodes
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• Functional Application: Voltage regulation and transient protection
• Product Status Consideration: The substitute (SZ2110.T) maintains active product status, ensuring ongoing availability and support

Parameter Comparison

Engineering Selection Recommendations

The SZ2110.T serves as an active substitute for the obsolete RY85_MBZ5240B. Selection of this substitute is supported by the following factors:

Product Status: The SZ2110.T maintains active product status with confirmed inventory availability (1259 pcs), whereas the RY85_MBZ5240B is obsolete. This ensures long-term supply chain reliability and continued manufacturer support.

Compliance and Certifications: The SZ2110.T is ROHS3 compliant and carries REACH Affected status, indicating current regulatory alignment. The original part's REACH Unaffected status reflects its obsolete classification.

Moisture Sensitivity: Both components share MSL 1 (Unlimited) rating, indicating equivalent moisture handling requirements and storage conditions.

Functional Category: Both parts are classified as Zener Diodes, confirming functional equivalence for voltage regulation and protection applications.

Component selection should be based on specific circuit requirements including nominal zener voltage, power dissipation limits, and operating temperature range. The SZ2110.T specifications (10 V nominal, 500 mW maximum power, -55°C to 150°C operating range) define its application envelope.
