ALE1PB09 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The ALE1PB09 is a general purpose relay manufactured by Panasonic Electric Works, configured as a single-pole single-throw normally open (SPST-NO) contact form with a 9VDC coil. This through-hole mounted relay is rated for 16A switching capacity at 277VAC maximum switching voltage. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where this relay specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALE1PB09 is determined by the following critical parameters that must remain constant or be exceeded:

• Coil voltage: 9VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Contact current rating: minimum 16A
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil type: Non Latching (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)

The ALZN5B09W meets all substitution criteria. While it offers improved electrical performance characteristics (higher maximum switching voltage and load capacity) and enhanced seal rating, it maintains identical coil voltage, contact form, mounting configuration, and termination style as the original ALE1PB09.

Parameter Comparison

Engineering Selection Recommendations

The ALZN5B09W is the direct substitute for the obsolete ALE1PB09. Both relays are manufactured by Panasonic Electric Works and share identical electrical specifications for coil voltage, contact form, current rating, and coil resistance.

The ALZN5B09W offers the advantage of active product status, ensuring continued availability and supply chain reliability. It exceeds the original part's electrical performance with higher maximum switching voltage (440VAC versus 277VAC) and greater maximum switching load (7040VA versus 4432VA), making it suitable for applications requiring the original ALE1PB09 specification.

Both parts maintain Class B coil insulation, identical operating temperature range (-40°C ~ 85°C), and equivalent contact material composition. The ALZN5B09W includes sealed flux protection, providing enhanced environmental protection compared to the original design.

Compliance certifications differ slightly: the ALE1PB09 carries CSA, TUV, UR, and VDE approvals, while the ALZN5B09W carries cURus and VDE approvals. Both parts are RoHS compliant and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5B09W directly replace the ALE1PB09 in existing circuit designs?

A: Yes. Both relays share identical coil voltage (9VDC), contact form (SPST-NO), current rating (16A), mounting type (through hole), and termination style (PC pin). The ALZN5B09W meets or exceeds all electrical parameters of the original part.

Q: What is the primary reason for substitution?

A: The ALE1PB09 is obsolete. The ALZN5B09W is an active product from the same manufacturer with equivalent core specifications and improved performance characteristics.

Q: Are there differences in switching performance between these relays?

A: The ALZN5B09W operates faster (15ms operate time versus 20ms, and 5ms release time versus 20ms) and has a lower must-operate voltage (6.3VDC versus 6.75VDC). These differences represent performance improvements suitable for the same application space.

Q: What is the difference in packaging between these parts?

A: The ALE1PB09 packaging is not specified in available documentation. The ALZN5B09W is supplied in tray packaging. Verify packaging requirements for your procurement process.

Q: Are both relays RoHS compliant?

A: Yes. The ALE1PB09 is RoHS Compliant. The ALZN5B09W is ROHS3 Compliant, representing a more current compliance standard.

Q: What certifications apply to each relay?

A: The ALE1PB09 carries CSA, TUV, UR, and VDE approvals. The ALZN5B09W carries cURus and VDE approvals. Verify that the certifications required for your application are present on the substitute part.
