SZX-SLF-14 Relay Socket 14 Position DIN Rail - Equivalent & Substitute Parts

Part Overview

The SZX-SLF-14 is a 14-position relay socket designed for DIN rail mounting, manufactured by Honeywell Sensing and Productivity Solutions. This component serves as an interface for SZR-LY series relays, providing screw terminal connections for electrical integration. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in applications where the original part is no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SZX-SLF-14 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Number of Positions: 14
• Mounting Type: DIN Rail
• Termination Style: Screw Terminal
• Socket Type: Relay Socket

Secondary Compatibility Factors:

• RoHS Compliance Status
• Moisture Sensitivity Level (MSL)
• ECCN Classification
• Relay Series Compatibility

The PTF14A from Omron Automation and Safety meets all primary substitution criteria. Both components feature identical position count, DIN rail mounting, and screw terminal configuration. Both maintain MSL Level 1 rating and EAR99 export classification. The PTF14A is compatible with LY series relays, which aligns with the SZR-LY series requirement of the original part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The PTF14A is the qualified equivalent for the SZX-SLF-14. Selection of this substitute is supported by:

1. Functional Equivalence: Identical position count (14), mounting configuration (DIN Rail), and termination method (Screw Terminal) ensure mechanical and electrical compatibility within the same application context.

2. Regulatory Compliance: Both components maintain RoHS compliance. The PTF14A carries ROHS3 certification, representing current regulatory standards. Both components are classified as EAR99 for export purposes.

3. Environmental Rating: Both components maintain MSL Level 1, indicating unlimited moisture sensitivity protection and equivalent reliability in standard industrial environments.

4. Product Availability: The PTF14A maintains active product status with current inventory availability (1172 Pcs), whereas the SZX-SLF-14 is obsolete. This availability differential supports the substitution for ongoing system support and maintenance.

5. Series Compatibility: The PTF14A is specified for LY series relays, which corresponds to the SZR-LY series requirement of the original component.

Frequently Asked Questions (FAQ)

Q: Can the PTF14A directly replace the SZX-SLF-14 in existing installations?

A: Yes. Both components share identical specifications for position count (14), DIN rail mounting, and screw terminal termination. The PTF14A is designed for LY series relays, which are compatible with SZR-LY series applications.

Q: What is the significance of the "Obsolete" status of the SZX-SLF-14?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. The PTF14A, with active product status, provides a current alternative for procurement and future system maintenance.

Q: Are there any compliance differences between the two components?

A: Both components are RoHS compliant. The PTF14A carries ROHS3 certification, which represents the current regulatory standard. Both maintain identical MSL Level 1 ratings and EAR99 export classification.

Q: Does packaging affect substitution compatibility?

A: Both components are supplied in bulk packaging. Packaging format does not affect functional or electrical compatibility for socket installation and relay interface applications.

Q: What parameters must remain identical for substitution to be valid?

A: Critical parameters for substitution validity are: number of positions (14), mounting type (DIN Rail), termination style (Screw Terminal), and socket type. The PTF14A maintains all these specifications.

Q: Is the PTF14A available in current inventory?

A: Yes. The PTF14A is listed as active product status with 1172 Pcs in current inventory, supporting immediate procurement for replacement and maintenance applications.
