ALE1PB05 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The ALE1PB05 is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 5VDC coil and 16A contact rating. This through-hole mounted relay is designed for switching applications up to 277VAC maximum. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALE1PB05 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 5VDC
• Contact Form: SPST-NO (1 Form A)
• Contact Rating (Current): 16 A
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Current: 80 mA
• Coil Resistance: 63 Ohms

Allowable Variation Parameters:

• Switching Voltage: Equal to or greater than 277VAC
• Load - Max Switching: Equal to or greater than 4432VA
• Operate/Release Time: May vary within acceptable switching performance windows
• Seal Rating: Enhanced sealing is acceptable
• Product Status: Active status preferred for obsolete parts
• Compliance Standards: Must maintain equivalent or superior certifications

The ALZN5B05W meets all mandatory matching parameters and exceeds allowable variation thresholds, qualifying it as a direct substitute for the ALE1PB05.

Parameter Comparison

Engineering Selection Recommendations

The ALZN5B05W is the qualified substitute for the obsolete ALE1PB05. Selection is based on the following engineering criteria:

Functional Equivalence: Both relays share identical coil voltage (5VDC), contact configuration (SPST-NO), current rating (16A), and coil parameters (80 mA, 63 Ohms). Electrical performance in standard switching applications is equivalent.

Enhanced Performance Margins: The ALZN5B05W provides superior switching voltage capability (440VAC vs. 277VAC) and maximum load switching capacity (7040VA vs. 4432VA), offering increased design margin for applications operating near the original part's limits.

Improved Switching Characteristics: The substitute exhibits faster release time (5 ms vs. 20 ms) and comparable operate time (15 ms vs. 20 ms), resulting in improved switching response.

Product Status and Compliance: The ALZN5B05W is active production status, ensuring long-term availability. ROHS3 compliance supersedes the original RoHS compliance. Both parts maintain VDE certification; the substitute adds cURus approval.

Packaging Consideration: The ALZN5B05W is supplied in Tray packaging versus the original part's unspecified packaging. Through-hole mounting and PC pin termination remain identical, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5B05W be used as a direct replacement for the ALE1PB05 on existing PCBs?

A: Yes. Both relays feature identical through-hole mounting, PC pin termination, and coil/contact specifications. No PCB modifications are required for substitution.

Q: What are the key differences between these two relays?

A: The ALZN5B05W provides higher switching voltage rating (440VAC vs. 277VAC), greater maximum load capacity (7040VA vs. 4432VA), faster release time (5 ms vs. 20 ms), and includes sealed flux protection. Coil voltage, current rating, and contact configuration are identical.

Q: Why is the ALE1PB05 obsolete?

A: The ALE1PB05 has been discontinued by Panasonic Electric Works. The ALZN5B05W represents the current production equivalent within the Panasonic relay portfolio.

Q: Are there any compatibility concerns with the substitute part?

A: No compatibility concerns exist for standard SPST-NO switching applications. The substitute's enhanced electrical ratings and faster switching characteristics are backward compatible with designs specified for the original part.

Q: Does the tray packaging of the ALZN5B05W affect component handling?

A: Tray packaging is standard for production quantities and does not affect individual component performance or PCB mounting. Handling procedures remain consistent with through-hole component assembly practices.

Q: What certifications apply to the substitute part?

A: The ALZN5B05W holds cURus and VDE approvals. Both certifications are recognized for industrial relay applications and meet the regulatory requirements of the original part's CSA, TUV, UR, and VDE approvals.
