Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALZ11F05 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Coil Voltage: 5VDC
• Contact Form: SPDT (1 Form C)
• Contact Rating: 16 A minimum
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching
• Coil Insulation: Class F

Allowable Variations:

• Switching Voltage: Substitute parts rated at 400VAC are acceptable as they operate within the application envelope of the 440VAC main part
• Operating Temperature Range: Substitute parts with -40°C ~ 85°C range are acceptable for applications not requiring the extended upper temperature capability of the main part
• Contact Material: Both Silver Tin Oxide (AgSnO) and Silver Nickel (AgNi) are acceptable contact materials for general purpose relay applications
• Seal Rating: Sealed - Flux Protection is preferred; unsealed variants may be acceptable depending on application environment

The following parts meet these substitution criteria: 5-1415899-2, RZ03-1C4-D005, and RT314005.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5-1415899-2, RZ03-1C4-D005, and RT314005) are qualified equivalents for the ALZ11F05 based on matching core electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Product Status and Compliance: All parts are active in production with current RoHS3 compliance certification. The ALZ11F05 carries RoHS Compliant status, while all substitute parts meet the more stringent ROHS3 standard, ensuring forward compatibility with evolving regulatory requirements.

Inventory Availability: RZ03-1C4-D005 offers the highest inventory level at 39,553 units in stock, followed by 5-1415899-2 with 3,677 units, and RT314005 with 1,400 units. The main part ALZ11F05 has 782 units available.

Temperature Operating Range: The ALZ11F05 operates to 105°C maximum, while all substitute parts are rated to 85°C maximum. Applications requiring operation above 85°C must retain the ALZ11F05. For applications with maximum ambient temperatures at or below 85°C, all substitute parts are suitable.

Switching Voltage Capability: The ALZ11F05 is rated for 440VAC maximum switching voltage. All substitute parts are rated for 400VAC maximum. Applications requiring switching voltages between 400VAC and 440VAC must use the ALZ11F05.

Contact Material Considerations: The ALZ11F05 and 5-1415899-2 feature Silver Tin Oxide (AgSnO) contact material. RZ03-1C4-D005 and RT314005 use Silver Nickel (AgNi) contact material. Both materials are suitable for general purpose relay applications; material selection should align with specific load characteristics and application requirements.

Switching Speed: The ALZ11F05 has an operate time of 15 ms and release time of 5 ms. All substitute parts offer faster switching with 8 ms operate time and 6 ms release time. Applications with timing-critical requirements may benefit from the faster switching characteristics of the substitute parts.

Frequently Asked Questions (FAQ)

Q: Can I use RZ03-1C4-D005 as a direct replacement for ALZ11F05 in all applications?

A: RZ03-1C4-D005 is a functional equivalent for most general purpose relay applications. However, verify that your application does not require operation above 85°C or switching voltages exceeding 400VAC, as the ALZ11F05 exceeds these specifications. Additionally, confirm that the faster switching times (8 ms operate vs. 15 ms operate) do not conflict with circuit timing requirements.

Q: What is the difference between Silver Tin Oxide and Silver Nickel contact materials?

A: Both Silver Tin Oxide (AgSnO) and Silver Nickel (AgNi) are standard contact materials for general purpose relays. The choice between them depends on specific load characteristics, including inductive vs. resistive loads and switching frequency. Consult application-specific load requirements to determine material suitability.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ALZ11F05 is RoHS Compliant. All three substitute parts (5-1415899-2, RZ03-1C4-D005, and RT314005) meet the more stringent ROHS3 Compliant standard, ensuring compatibility with current and future environmental regulations.

Q: What is the impact of the 40VAC difference in switching voltage rating?

A: The ALZ11F05 is rated for 440VAC maximum switching voltage, while substitute parts are rated for 400VAC maximum. For applications switching voltages at or below 400VAC, all parts are equivalent. Applications requiring switching voltages between 400VAC and 440VAC must use the ALZ11F05 to maintain design margin and reliability.

Q: Do the substitute parts have the same seal rating as the ALZ11F05?

A: The ALZ11F05 and 5-1415899-2 both carry Sealed - Flux Protection rating. RT314005 also carries this rating. RZ03-1C4-D005 does not specify a seal rating in the provided data. For applications requiring sealed relay construction, confirm seal rating specifications before selection.

Q: Can I use a substitute part with faster switching times in a circuit designed for the ALZ11F05?

A: The substitute parts offer faster switching (8 ms operate time vs. 15 ms for the ALZ11F05). In most general purpose applications, faster switching is beneficial and does not create compatibility issues. However, circuits with timing-dependent logic or specific switching delay requirements should be evaluated to ensure the faster response does not affect circuit function.

Q: What is the coil resistance tolerance, and does it affect substitution?

A: Coil resistance values are 63 Ohms (ALZ11F05), 60 Ohms (5-1415899-2 and RZ03-1C4-D005), and 62 Ohms (RT314005). These variations are within acceptable tolerance for general purpose relay applications and do not prevent substitution. All parts meet the same must-operate and must-release voltage specifications (4.6 VDC and 0.5 VDC respectively).
