ALE7PF05 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The ALE7PF05 is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 5VDC coil. This through-hole mounted relay is rated for 16A at 277VAC maximum switching voltage and is designed for standard industrial and commercial switching applications.

The ALE7PF05 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 ALE7PF05 is determined by the following critical parameters:

• Coil Voltage: Must be 5VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Contact Rating (Current): Must be rated for minimum 16A to support the same 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

The ALZN5F05W meets all critical substitution criteria. While this substitute exhibits enhanced electrical performance characteristics (higher switching voltage rating, improved operating temperature range, and faster switching times), these represent improvements over the original specification and do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ALZN5F05W is the qualified substitute for the obsolete ALE7PF05. Both relays are manufactured by Panasonic Electric Works and share identical core electrical specifications: 5VDC coil voltage, SPST-NO contact configuration, 16A current rating, and through-hole PC pin termination.

The ALZN5F05W is currently in active production status, ensuring supply chain availability and long-term support. The substitute maintains full compliance with RoHS3 standards and carries VDE certification alongside cURus approval, meeting modern regulatory requirements.

The ALZN5F05W demonstrates superior performance characteristics across multiple parameters: maximum switching voltage increases from 277VAC to 440VAC, maximum switching load increases from 4432VA to 7040VA, and operating temperature range extends to 105°C. Switching response times are improved, with operate time reduced from 20ms to 15ms and release time reduced from 25ms to 5ms. These enhancements provide additional design margin and operational reliability without introducing compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5F05W directly replace the ALE7PF05 in existing designs?

A: Yes. Both relays share identical coil voltage (5VDC), contact form (SPST-NO), current rating (16A), mounting type (through-hole), and termination style (PC pin). Direct substitution is electrically and mechanically compatible.

Q: What are the key differences between these relays?

A: The ALZN5F05W offers enhanced performance: higher maximum switching voltage (440VAC vs. 277VAC), greater maximum switching load (7040VA vs. 4432VA), extended operating temperature range (-40°C to 105°C vs. -40°C to 85°C), and faster switching response times. These represent improvements that do not compromise compatibility.

Q: Why does the ALZN5F05W have higher coil current (80mA vs. 40mA)?

A: The ALZN5F05W operates at lower coil resistance (63 Ohms vs. 125 Ohms), resulting in higher coil current at the same 5VDC supply voltage. This design change supports the relay's enhanced performance characteristics and improved switching speed.

Q: Are there packaging differences between these relays?

A: The ALE7PF05 is supplied without specified packaging, while the ALZN5F05W is supplied in trays. Both are through-hole mounted components with PC pin termination suitable for PCB assembly.

Q: What certifications apply to the ALZN5F05W?

A: The ALZN5F05W carries cURus and VDE approvals and is ROHS3 compliant. These certifications meet current regulatory standards for industrial and commercial relay applications.

Q: Is the ALZN5F05W sealed?

A: Yes. The ALZN5F05W features sealed construction with flux protection, providing enhanced protection against environmental contamination compared to the original ALE7PF05.
