ALE1PB24 Equivalent & Substitute Parts

Part Overview

The ALE1PB24 is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 24VDC coil and 16A contact rating. This through-hole mounted relay is designed for industrial control applications requiring single-pole, single-throw switching functionality at 277VAC maximum switching voltage.

The ALE1PB24 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALE1PB24 is determined by the following critical parameters:

• Coil Voltage: Must be 24VDC to ensure direct compatibility with existing control circuits
• Contact Form: Must be SPST-NO (1 Form A) to maintain switching topology
• Contact Rating (Current): Must be rated for minimum 16A to support the original load requirements
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct connection to printed circuit boards
• Coil Resistance: Must be 1.44 kOhms to maintain consistent coil impedance and drive circuit performance
• Operating Temperature Range: Must support -40°C ~ 85°C minimum to match environmental specifications

The ALZN5B24W meets all critical substitution criteria. While this substitute exhibits enhanced electrical performance characteristics (higher maximum switching voltage and load capacity), it maintains full backward compatibility with the ALE1PB24 in applications where the original relay was specified.

Parameter Comparison

Engineering Selection Recommendations

The ALZN5B24W is the direct substitute for the obsolete ALE1PB24. Both relays are manufactured by Panasonic Electric Works and share identical core electrical specifications: 24VDC coil voltage, SPST-NO contact configuration, 16A contact rating, 1.44 kOhms coil resistance, and -40°C ~ 85°C operating temperature range.

The ALZN5B24W is currently in active production status, ensuring long-term supply availability compared to the obsolete ALE1PB24. The substitute provides enhanced electrical performance with 440VAC maximum switching voltage (versus 277VAC) and 7040VA maximum load capacity (versus 4432VA), offering improved margin for demanding applications.

Both parts maintain RoHS compliance and carry relevant regulatory approvals (CSA, TUV, UR, VDE for the original; cURus, VDE for the substitute). The ALZN5B24W includes sealed flux protection, providing additional environmental protection in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5B24W directly replace the ALE1PB24 in existing designs?

A: Yes. Both relays share identical coil voltage (24VDC), contact form (SPST-NO), current rating (16A), coil resistance (1.44 kOhms), and mounting configuration (through-hole PC pin termination). No circuit modifications are required.

Q: What is the primary reason to substitute the ALE1PB24?

A: The ALE1PB24 is obsolete. The ALZN5B24W is the active equivalent from the same manufacturer, ensuring continued availability for new production and maintenance applications.

Q: Are there packaging differences between these relays?

A: The ALE1PB24 is supplied in standard packaging, while the ALZN5B24W is supplied in trays. Both are through-hole mounted components with PC pin termination suitable for PCB assembly.

Q: Does the ALZN5B24W offer any performance advantages?

A: The ALZN5B24W supports higher maximum switching voltage (440VAC versus 277VAC) and greater maximum load capacity (7040VA versus 4432VA). It also includes sealed flux protection. These enhancements provide additional design margin without affecting compatibility with the original ALE1PB24 specification.

Q: Are both relays RoHS compliant?

A: Yes. The ALE1PB24 is RoHS Compliant, and the ALZN5B24W is ROHS3 Compliant, meeting current environmental standards.

Q: What regulatory approvals apply to each relay?

A: The ALE1PB24 carries CSA, TUV, UR, and VDE approvals. The ALZN5B24W carries cURus and VDE approvals. Both meet relevant industrial control standards.
