ALZ11F09W Equivalent & Substitute Parts

Part Overview

The ALZ11F09W is a general purpose relay manufactured by Panasonic Electric Works, featuring a single pole double throw (SPDT) contact configuration with a 9VDC coil. This through-hole mounted relay is designed for applications requiring 16A switching capacity at up to 440VAC. The part is currently active in production with 1054 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

The RZ03-1C4-D009 manufactured by TE Connectivity Potter & Brumfield Relays qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• Coil voltage: 9VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 16 A
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Coil insulation: Class F
• Must operate voltage: 6.3 VDC
• Must release voltage: 0.9 VDC
• Coil current: 44.4 mA
• RoHS compliance status: Active

These parameters define the functional and physical compatibility required for direct substitution in applications designed for the ALZ11F09W.

Parameter Comparison

Engineering Selection Recommendations

Both the ALZ11F09W and RZ03-1C4-D009 are active production components with equivalent RoHS compliance status. The ALZ11F09W provides a maximum switching voltage of 440VAC and an extended operating temperature range to 105°C. The RZ03-1C4-D009 operates to 85°C maximum and switches up to 400VAC, with faster operate time (8 ms versus 15 ms). Selection between these parts depends on application requirements for maximum switching voltage and temperature range. Both parts carry ECCN EAR99 classification and HTSUS code 8536.41.0050.

Frequently Asked Questions (FAQ)

Q: Can RZ03-1C4-D009 replace ALZ11F09W in all applications?

A: Substitution is valid when the application does not require switching voltages above 400VAC or operating temperatures above 85°C. Both parts share identical coil voltage, contact form, current rating, and control voltage specifications.

Q: What are the differences in switching performance?

A: The RZ03-1C4-D009 operates faster (8 ms versus 15 ms) but has a slightly longer release time (6 ms versus 5 ms). The ALZ11F09W handles higher switching voltages (440VAC maximum).

Q: Are there packaging differences?

A: Yes. The ALZ11F09W is supplied in bulk packaging, while the RZ03-1C4-D009 is supplied in tube packaging. Both use PC pin termination for through-hole mounting.

Q: Do both parts meet RoHS requirements?

A: Yes. The ALZ11F09W is RoHS Compliant, and the RZ03-1C4-D009 is ROHS3 Compliant. Both are suitable for applications requiring RoHS compliance.

Q: What is the difference in contact material?

A: The ALZ11F09W uses Silver Tin Oxide (AgSnO) contacts, while the RZ03-1C4-D009 uses Silver Nickel (AgNi) contacts. Both materials are suitable for general purpose relay applications at the specified current and voltage ratings.
