ALZ22F05W Equivalent & Substitute Parts

Part Overview

The ALZ22F05W is a general purpose relay manufactured by Panasonic Electric Works, configured as a single-pole single-throw normally open (SPST-NO) contact form with a 5VDC coil. This through-hole mounted relay is rated for 16A switching capacity at 440VAC maximum and is designed for non-latching operation in industrial control and switching applications.

The ALZ22F05W is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALZ22F05W is determined by strict equivalence across the following critical parameters:

• Contact Form: SPST-NO (1 Form A) configuration
• Coil Voltage: 5VDC nominal
• Contact Rating: 16A minimum
• Mounting Type: Through Hole with PC Pin termination
• Coil Type: Non Latching operation
• Coil Insulation: Class F minimum
• Must Operate and Release Voltages: 4.6 VDC and 0.5 VDC respectively
• Moisture Sensitivity Level: MSL 1 (Unlimited)

All four substitute parts listed meet these core electrical and mechanical requirements. Variations in switching voltage maximum (400VAC vs. 440VAC), operating temperature upper limit (85°C vs. 105°C), contact material composition, and coil current specifications do not preclude substitution when the application requirements fall within the substitute part's rated parameters.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are manufactured by TE Connectivity Potter & Brumfield Relays and carry active product status, ensuring ongoing availability and supply chain support. Each substitute meets the core electrical specifications of the ALZ22F05W.

For applications operating within the 400VAC switching voltage range, all substitutes are directly equivalent. Applications requiring the full 440VAC switching capability of the original ALZ22F05W should be evaluated against the 400VAC maximum rating of the substitutes.

For applications requiring operation above 85°C, the 6-1415899-4 substitute maintains the full -40°C to 105°C operating range of the original part. The remaining three substitutes (RT334005, RZ03-1A3-D005, RZ03-1A4-D005) are rated to 85°C maximum.

All substitutes carry ROHS3 compliance and REACH Unaffected status, supporting modern regulatory requirements. Contact material differences (Silver Nickel vs. Silver Tin Oxide) do not affect substitution eligibility when application load characteristics remain within rated parameters.

Frequently Asked Questions (FAQ)

Q: Can the ALZ22F05W be directly replaced with any of these substitute parts?

A: Direct replacement is possible when the application switching voltage does not exceed 400VAC and operating temperature does not exceed 85°C. For applications requiring 440VAC switching capability or operation above 85°C, only the 6-1415899-4 substitute maintains full compatibility with the original ALZ22F05W specifications.

Q: What is the significance of the contact material difference between Silver Tin Oxide and Silver Nickel?

A: Both contact materials are specified in the substitute parts and meet the electrical requirements for 16A switching at the rated voltages. Material selection does not affect substitution eligibility when load characteristics remain within the relay's rated parameters.

Q: Are all substitute parts available in the same packaging as the original ALZ22F05W?

A: The 6-1415899-4 is supplied in Bulk packaging. The RT334005, RZ03-1A3-D005, and RZ03-1A4-D005 are supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility for through-hole PC pin mounted applications.

Q: What is the difference in operate and release times between the original and substitute parts?

A: The ALZ22F05W operates in 15 ms with 5 ms release time. All substitute parts operate in 8 ms with 6 ms release time. These timing differences must be evaluated against application requirements; faster operation may affect circuit behavior in time-sensitive applications.

Q: Do all substitute parts meet current regulatory compliance standards?

A: All four substitute parts are ROHS3 compliant and REACH Unaffected. The original ALZ22F05W RoHS status is not specified. Substitution with any of these parts ensures compliance with current environmental and regulatory standards.
