Substitute Part Grouping Explanation

Substitution eligibility for the SZX-SLF-08N is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 8
• Mounting Type: DIN Rail
• Termination Style: Screw Terminal
• Product Type: Relay Socket

Secondary Compliance Criteria:

• RoHS Compliance Status
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99

The PTF08A manufactured by Omron Automation and Safety satisfies all primary matching criteria and maintains equivalent compliance certifications. Both components are classified under ECCN EAR99 and possess MSL rating of 1, indicating identical environmental handling requirements. The PTF08A is compatible with LY series relays, which aligns with the SZR-LY series compatibility of the original part.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement:

The PTF08A represents a direct functional equivalent for the SZX-SLF-08N. Both components share identical electrical and mechanical specifications across all critical parameters: 8-position configuration, DIN rail mounting, and screw terminal termination. The PTF08A maintains active product status, ensuring continued availability and manufacturer support.

Compliance Considerations:

Both components satisfy RoHS requirements. The PTF08A carries ROHS3 certification, representing the current regulatory standard, while the SZX-SLF-08N holds RoHS Compliant status. Both components are classified as ECCN EAR99 and carry identical MSL ratings, confirming equivalent environmental and regulatory handling requirements.

Supply Chain Advantage:

The PTF08A is currently in active production with 4,563 units in stock, compared to the obsolete SZX-SLF-08N with limited remaining inventory of 621 units. Selection of the PTF08A ensures long-term component availability for maintenance and future production requirements.

Frequently Asked Questions (FAQ)

Q: Can the PTF08A directly replace the SZX-SLF-08N in existing installations?

A: Yes. Both components are 8-position relay sockets with DIN rail mounting and screw terminal termination. The electrical and mechanical interfaces are equivalent, allowing direct substitution in applications designed for the SZX-SLF-08N.

Q: What is the significance of the obsolete status of the SZX-SLF-08N?
