ALFG1PF09 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The ALFG1PF09 is a general purpose relay manufactured by Panasonic Electric Works, configured as a Single Pole Single Throw Normally Open (SPST-NO) relay with a 9VDC coil. This through-hole mounted relay is designed for switching applications up to 22A at 250VAC maximum, with a maximum switching load of 5500VA. The part is currently active in production with 909 units in stock. Substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and regulatory compliance, enabling direct replacement in circuit designs without modification.

Key Parameters

Substitute Part Grouping Explanation

The ALFG1PF091 is identified as a parametric equivalent to the ALFG1PF09 based on the following critical substitution criteria:

• Identical coil voltage specification (9VDC)
• Identical contact form and configuration (SPST-NO, 1 Form A)
• Identical current rating (22A)
• Identical switching voltage maximum (250VAC)
• Identical maximum switching load (5500VA)
• Identical mounting type (Through Hole)
• Identical termination style (PC Pin)
• Identical coil resistance (58 Ohms)
• Identical coil current (155 mA)
• Identical operating temperature range (-40°C to 60°C)
• Identical contact material (Silver Tin Oxide)
• Identical regulatory approvals (cURus, VDE)
• Identical series designation (ALFG)

Both parts maintain the same functional and electrical characteristics required for direct substitution in applications designed for the ALFG1PF09.

Parameter Comparison

Engineering Selection Recommendations

Both the ALFG1PF09 and ALFG1PF091 are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. The ALFG1PF091 carries ROHS3 compliance status compared to the RoHS compliance designation of the ALFG1PF09. Both parts maintain cURus and VDE regulatory approvals. Selection between these parts should be based on inventory availability and specific regulatory requirements of the end application. The ALFG1PF09 currently has higher inventory availability at 909 units compared to 787 units for the ALFG1PF091.

Frequently Asked Questions (FAQ)

Q: Can ALFG1PF091 be used as a direct replacement for ALFG1PF09?

A: Yes. Both parts are identical in all critical electrical parameters including coil voltage, contact rating, switching voltage, current capacity, and operating temperature range. Both are through-hole mounted with PC pin termination and maintain the same regulatory approvals.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents a more recent compliance designation. Both statuses indicate compliance with Restriction of Hazardous Substances regulations. The ALFG1PF091 carries the updated ROHS3 designation while the ALFG1PF09 carries the RoHS designation. Both are compliant with hazardous substance restrictions.

Q: Are there any inventory considerations when selecting between these parts?

A: The ALFG1PF09 has 909 units in stock while the ALFG1PF091 has 787 units available. Inventory levels may influence selection based on project timeline and quantity requirements.

Q: Do both parts have the same regulatory approvals?

A: Yes. Both the ALFG1PF09 and ALFG1PF091 carry identical approvals from cURus and VDE, ensuring compliance with the same regulatory standards.

Q: What are the critical parameters that define substitutability for this relay?

A: Substitutability is determined by matching coil voltage (9VDC), contact form (SPST-NO), current rating (22A), switching voltage (250VAC maximum), mounting type (Through Hole), termination style (PC Pin), and operating temperature range (-40°C to 60°C). Both parts meet all these criteria identically.
