Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SZX-SMB-08 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Number of Positions: 8
• Mounting Type: Panel Mount
• Termination Style: Solder Lug
• Type: Socket
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters:

• RoHS Status: Compliant (both main and substitute meet environmental standards)
• ECCN Classification: EAR99 (export control alignment)

The substitute part PY08 satisfies all critical parameters, enabling direct functional replacement in applications originally designed for the SZX-SMB-08. Both parts are classified as 8-position panel mount solder lug sockets with identical moisture sensitivity ratings, ensuring compatibility in equivalent operating environments.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PY08 (Omron Automation and Safety)

The PY08 is the qualified substitute for the SZX-SMB-08 based on the following engineering criteria:

1. Functional Equivalence: All critical electrical and mechanical parameters match exactly, including 8-position configuration, panel mount installation, and solder lug termination.

2. Compliance Status: The PY08 maintains RoHS3 compliance, which exceeds the RoHS compliance requirement of the original part, ensuring regulatory alignment for current and future applications.

3. Product Availability: The PY08 is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete SZX-SMB-08.

4. Environmental Compatibility: Both parts share identical Moisture Sensitivity Level (MSL 1 - Unlimited), confirming equivalent handling, storage, and operational environmental requirements.

5. Export Classification: Both parts carry EAR99 classification, maintaining consistent export control compliance.

The PY08 is suitable for direct replacement in new designs and maintenance applications where the SZX-SMB-08 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the PY08 be used as a direct replacement for the SZX-SMB-08 in existing assemblies?

A: Yes. The PY08 matches all critical parameters: 8-position count, panel mount configuration, solder lug termination, and MSL 1 rating. Physical and electrical compatibility is confirmed.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current iteration of the RoHS Directive with updated substance restrictions. ROHS3 compliance is a superset of RoHS compliance, meaning the PY08 meets or exceeds the environmental standards of the SZX-SMB-08.

Q: Why is the SZX-SMB-08 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The PY08 provides functional continuity for applications requiring 8-position panel mount relay sockets.

Q: Are there packaging differences between the SZX-SMB-08 and PY08?

A: The SZX-SMB-08 is packaged with a dash designation (not specified), while the PY08 is supplied in Bulk packaging. Both are suitable for solder lug termination applications; packaging selection depends on order quantity and assembly requirements.

Q: What relay series is the PY08 compatible with?

A: The PY08 is designed for use with MY2 relays. Verify relay compatibility with your specific application requirements.

Q: Do both parts have the same HTSUS classification?

A: The parts have similar but distinct HTSUS codes: SZX-SMB-08 is 8536.69.4040, and PY08 is 8536.69.4030. Both fall within the same product category for tariff purposes.
