SZL-VL-J Equivalent & Substitute Parts Reference

Part Overview

The SZL-VL-J is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with screw terminal connections. This switch is rated for 5A AC at 250V and 400mA DC at 125V, featuring a side rotary adjustable roller actuator and IP64 ingress protection. The product is currently obsolete, necessitating identification of functionally compatible alternatives for ongoing maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The SZL-VL-J has been identified with one direct substitute within the Honeywell SZL-VL series: SZL-VL-S-J-N-M. Substitution eligibility is determined by the following parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Actuator type: Side Rotary, Adjustable Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Manufacturer: Honeywell Sensing and Productivity Solutions

Electrical Parameter Considerations: The substitute part operates at different current and voltage ratings. The SZL-VL-S-J-N-M is rated for 500mA AC at 380V and 50mA DC at 220V, representing higher AC voltage capability but lower current capacity compared to the original SZL-VL-J.

Environmental and Mechanical Parameters: The substitute provides enhanced ingress protection (IP67 versus IP64) and maintains the same mechanical life rating of 10,000,000 cycles. Operating temperature range extends to 70°C maximum.

Parameter Comparison

Engineering Selection Recommendations

The SZL-VL-S-J-N-M serves as the active production equivalent to the obsolete SZL-VL-J. Both parts maintain identical mechanical and functional architecture within the SZL-VL series platform, ensuring physical and electrical interface compatibility for chassis mount applications.

Compliance Status: Both the original and substitute parts are RoHS Compliant and carry ECCN EAR99 classification. The substitute part is additionally REACH Unaffected, providing regulatory advantage for international applications.

Product Availability: The SZL-VL-J is obsolete with limited inventory (787 pieces). The SZL-VL-S-J-N-M is active production status with current inventory (754 pieces), ensuring long-term supply chain continuity.

Electrical Derating Consideration: Applications requiring the full 5A AC current capacity of the original SZL-VL-J cannot directly substitute the SZL-VL-S-J-N-M, which is rated for 500mA AC maximum. Circuit designs operating within 500mA AC and 50mA DC parameters are fully compatible. Higher current applications require alternative component selection outside the SZL-VL series.

Frequently Asked Questions (FAQ)

Q: Can the SZL-VL-S-J-N-M directly replace the SZL-VL-J in all applications?

A: Physical and functional replacement is possible for applications within the electrical ratings of the substitute part. The SZL-VL-S-J-N-M is rated for 500mA AC maximum, compared to 5A AC for the original. Applications requiring currents exceeding 500mA AC are not compatible with this substitute.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical mounting type (Chassis Mount), termination style (Screw Terminal), actuator configuration (Side Rotary, Adjustable Roller), and circuit topology (SPDT DB/DM). Physical installation and wiring connections are interchangeable.

Q: How do the ingress protection ratings differ?

A: The SZL-VL-J provides IP64 protection (dust tight, water resistant). The SZL-VL-S-J-N-M provides IP67 protection (dust tight, waterproof). The substitute offers enhanced environmental sealing suitable for more demanding moisture exposure conditions.

Q: What is the operating temperature difference?

A: The SZL-VL-J operates from -20°C to 60°C. The SZL-VL-S-J-N-M extends the upper limit to 70°C, providing 10°C additional high-temperature capability.

Q: Are there packaging differences between these parts?

A: The SZL-VL-J packaging is listed as dash (-). The SZL-VL-S-J-N-M is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: What is the electrical life specification for each part?

A: The SZL-VL-J does not specify electrical life. The SZL-VL-S-J-N-M specifies 500,000 electrical cycles. Both parts maintain 10,000,000 mechanical life cycles.

Q: Are both parts RoHS compliant?

A: Yes, both the SZL-VL-J and SZL-VL-S-J-N-M are RoHS Compliant. The substitute additionally carries REACH Unaffected status.
