Matching Parameters:

• Coil Voltage: 9VDC (identical)
• Contact Form: SPDT (1 Form C) (identical)
• Contact Rating: 16 A (identical)
• Coil Type: Non Latching (identical)
• Mounting Type: Through Hole (identical)
• Termination Style: PC Pin (identical)
• Coil Insulation: Class F (identical)
• Must Operate Voltage: 6.3 VDC (identical)
• Must Release Voltage: 0.9 VDC (identical)
• Coil Resistance: 200 Ohms (within tolerance)
• RoHS Compliance: Both parts meet RoHS standards

Substitution is valid where these core electrical and mechanical parameters align, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the ALZ11F09 and RZ03-1C4-D009 are active production parts with full RoHS compliance. The ALZ11F09 supports a higher maximum switching voltage (440VAC vs. 400VAC) and operates across a wider temperature range (-40°C to 105°C vs. -40°C to 85°C). The RZ03-1C4-D009 offers faster operate time (8 ms vs. 15 ms). Selection between these parts should be based on specific application requirements regarding maximum switching voltage, temperature operating range, and switching speed performance. Both parts carry identical coil voltage, contact configuration, current rating, and coil insulation specifications, supporting direct substitution in applications where the noted parameter differences are acceptable.

Frequently Asked Questions (FAQ)

Q: Can RZ03-1C4-D009 directly replace ALZ11F09 in all applications?

A: Direct replacement is valid where the application does not require operation above 400VAC switching voltage or temperatures exceeding 85°C. Both parts share identical coil voltage (9VDC), contact form (SPDT), current rating (16A), and coil characteristics (Non Latching, Class F insulation).

Q: What are the key differences between these two relays?

A: The primary differences are maximum switching voltage (ALZ11F09: 440VAC; RZ03-1C4-D009: 400VAC), operating temperature range (ALZ11F09: -40°C to 105°C; RZ03-1C4-D009: -40°C to 85°C), operate time (ALZ11F09: 15 ms; RZ03-1C4-D009: 8 ms), and contact material (ALZ11F09: Silver Tin Oxide; RZ03-1C4-D009: Silver Nickel).

Q: Are both parts RoHS compliant?

A: Yes. The ALZ11F09 is RoHS Compliant, and the RZ03-1C4-D009 is ROHS3 Compliant. Both meet applicable RoHS standards.

Q: Do these relays have identical through-hole mounting and PC pin termination?

A: Yes. Both parts feature through-hole mounting and PC pin termination, supporting identical PCB layout and assembly processes.

Q: What is the coil resistance tolerance between these parts?

A: The ALZ11F09 has 203 Ohms coil resistance while the RZ03-1C4-D009 has 200 Ohms. This 3-ohm difference is within typical engineering tolerance for relay coil specifications.
