Key Parameters

Substitute Part Grouping Explanation

Substitution for the ALZ22F09 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 9VDC
• Contact configuration: SPST-NO (1 Form A)
• Contact current rating: 16 A minimum
• Mounting type: Through hole
• Termination style: PC pin
• Coil resistance: 203 Ohms (±tolerance)
• Seal rating: Sealed construction
• Coil insulation class: Class F

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical and mechanical specifications across all critical parameters. These parts are direct replacements with no functional or performance differences.

Similar Parts share the same contact configuration, coil voltage, current rating, and mounting type but may differ in secondary parameters such as switching voltage maximum, operating temperature range, contact material composition, or timing characteristics. These parts are functionally compatible for most applications but require verification of specific performance requirements.

Parameter Comparison

Engineering Selection Recommendations

Panasonic ALZ52F09 and ALZ52F09T are parametric equivalents to the ALZ22F09. Both parts maintain identical electrical specifications, contact configuration, coil voltage, current rating, and operating temperature range. The primary distinction between these two is packaging format (both supplied in tube). Both ALZ52F09 and ALZ52F09T carry active product status and RoHS compliance, making them suitable for new designs and ongoing production requiring direct functional replacement of the obsolete ALZ22F09.

TE Connectivity 1-1415540-6 is a similar part with matching coil voltage, contact configuration, current rating, and mounting type. This part is classified as obsolete. The switching voltage maximum is 400VAC compared to 440VAC for the ALZ22F09, and contact material differs (Silver Nickel versus Silver Tin Oxide). This part is suitable only where the 400VAC switching voltage specification is adequate for the application.

TE Connectivity RZ03-1A4-D009 is a similar part with active product status and ROHS3 compliance. It matches the ALZ22F09 in coil voltage, contact configuration, current rating, and mounting type. The operating temperature range is limited to -40°C ~ 85°C (versus -40°C ~ 105°C for the ALZ22F09), and switching voltage maximum is 400VAC. The coil resistance is 200 Ohms, within acceptable tolerance of the 203 Ohm specification. This part is suitable for applications where the reduced upper operating temperature limit and 400VAC switching voltage are compatible with system requirements.

For applications requiring the full 440VAC switching voltage capability and 105°C upper operating temperature, select ALZ52F09 or ALZ52F09T. For applications compatible with 400VAC switching voltage and 85°C maximum operating temperature, RZ03-1A4-D009 provides an active, compliant alternative.

Frequently Asked Questions (FAQ)

Q: Can ALZ52F09 or ALZ52F09T be used as direct replacements for ALZ22F09?

A: Yes. Both ALZ52F09 and ALZ52F09T are parametric equivalents with identical coil voltage (9VDC), contact configuration (SPST-NO), current rating (16A), coil resistance (203 Ohms), and operating temperature range (-40°C ~ 105°C). No circuit modifications are required.

Q: What is the difference between ALZ52F09 and ALZ52F09T?

A: Both parts are electrically and mechanically identical. The designation difference reflects packaging or internal manufacturing variations. Both are supplied in tube packaging and carry active product status with RoHS compliance.

Q: Can RZ03-1A4-D009 replace ALZ22F09 in all applications?

A: RZ03-1A4-D009 is functionally compatible for most applications but has two specification differences: maximum operating temperature is 85°C (versus 105°C) and maximum switching voltage is 400VAC (versus 440VAC). Verify that your application does not require operation above 85°C or switching voltages exceeding 400VAC before selecting this part.

Q: Why does 1-1415540-6 show as obsolete if it is listed as a substitute?

A: 1-1415540-6 is a similar part that shares critical functional parameters but is no longer in active production. It is included for reference in legacy system documentation and repair scenarios where existing inventory may be available. For new designs, select active parts such as ALZ52F09, ALZ52F09T, or RZ03-1A4-D009.

Q: What is the significance of contact material differences (AgSnO versus AgNi)?

A: Contact material affects performance in specific switching environments. Silver Tin Oxide (AgSnO) contacts, used in ALZ22F09, ALZ52F09, and ALZ52F09T, provide superior performance in low-level signal switching and resistance to contact wear. Silver Nickel (AgNi) contacts, used in 1-1415540-6 and RZ03-1A4-D009, offer different wear characteristics. For the specified 16A switching application, both materials are suitable, but verify compatibility with your specific load type and switching frequency.

Q: Are there compliance or certification differences between substitute parts?

A: ALZ52F09 and ALZ52F09T carry RoHS compliance. RZ03-1A4-D009 carries ROHS3 compliance. 1-1415540-6 carries ROHS3 compliance but is obsolete. All parts carry cURus and VDE approvals (ALZ series) or equivalent certifications. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What packaging options are available?

A: ALZ22F09 is supplied in bulk packaging. ALZ52F09, ALZ52F09T, 1-1415540-6, and RZ03-1A4-D009 are all supplied in tube packaging. Confirm packaging compatibility with your procurement and assembly processes.
