ALZ22F09W Equivalent & Substitute Parts

Part Overview

The ALZ22F09W is a general purpose relay manufactured by Panasonic Electric Works, featuring SPST-NO (1 Form A) contact configuration with 16A switching capacity at 9VDC coil voltage. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The relay is designed for through-hole mounting with PC pin termination and operates across an industrial temperature range of -40°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALZ22F09W is determined by strict alignment of the following critical parameters:

• Coil voltage: 9VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Contact rating: 16 A minimum (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)
• Coil type: Non latching (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical criteria. Variations in switching voltage, contact material, operate/release timing, and operating temperature range are within acceptable engineering tolerances for general purpose relay applications and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the ALZ22F09W. Selection between alternatives should be based on the following factors:

1-1415540-6 (TE Connectivity Potter & Brumfield Relays)

• Maintains identical coil resistance (203 Ohms) and operating temperature range (-40°C to 105°C)
• Shares obsolete product status with the main part
• ROHS3 compliant with REACH affected designation
• Suitable for applications requiring exact thermal performance matching

RZ03-1A4-D009 (TE Connectivity Potter & Brumfield Relays)

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliant with REACH unaffected designation
• Coil resistance within 1.5% tolerance (200 Ohms vs. 203 Ohms)
• Operating temperature range limited to -40°C to 85°C; not suitable for applications requiring operation above 85°C
• Faster switching response (8 ms operate/6 ms release vs. 15 ms/5 ms)

For new designs and long-term production requirements, RZ03-1A4-D009 is preferred due to active product status. For legacy system maintenance where thermal performance above 85°C is required, 1-1415540-6 provides closer parameter alignment.

Frequently Asked Questions (FAQ)

Q: Can RZ03-1A4-D009 be used in applications operating above 85°C? A: No. The RZ03-1A4-D009 operating temperature range is -40°C to 85°C, while the ALZ22F09W operates to 105°C. Applications requiring operation above 85°C must use 1-1415540-6.

Q: What is the impact of different contact materials (AgSnO vs. AgNi)? A: Contact material differences do not affect substitution eligibility for general purpose relay applications. Both materials are suitable for 16A switching at the specified voltage levels.

Q: Are there packaging differences between substitute parts? A: Both substitute parts are supplied in tube packaging, consistent with the original ALZ22F09W specification.

Q: How do switching time differences affect compatibility? A: The substitute parts exhibit faster switching times (8 ms operate/6 ms release) compared to the main part (15 ms operate/5 ms release). This represents an improvement in switching performance and does not create compatibility issues in standard general purpose relay applications.

Q: What is the significance of REACH and RoHS compliance differences? A: Both substitute parts are ROHS3 compliant. The REACH affected status of 1-1415540-6 versus REACH unaffected status of RZ03-1A4-D009 reflects regulatory classification differences and should be evaluated against specific regional compliance requirements for the end application.

Q: Is the 3-Ohm coil resistance difference between parts significant? A: The 200-Ohm coil resistance of RZ03-1A4-D009 represents a 1.5% deviation from the 203-Ohm specification of the main part. This tolerance is within standard engineering practice for relay coil specifications and does not affect functional equivalence.
