ALE1PF05 Equivalent & Substitute Parts

Part Overview

The ALE1PF05 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 general switching applications with a maximum switching voltage of 277VAC and load capacity of 4432VA. The part is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this relay specification remains applicable.

Substitute Part Grouping Explanation

Substitution of the ALE1PF05 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 5VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Contact rating: 16A minimum (equal or higher acceptable)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil resistance: 63 Ohms (exact match required)
• Coil current: 80 mA (exact match required)
• Contact material: Silver Tin Oxide (AgSnO) (exact match required)

The ALZN5F05W meets all critical substitution criteria. While this substitute demonstrates improved electrical performance characteristics (higher switching voltage, increased load capacity, faster release time, and extended operating temperature range), these enhancements do not preclude its use as a direct substitute in applications originally designed for the ALE1PF05.

Parameter Comparison

Engineering Selection Recommendations

The ALZN5F05W is the qualified substitute for the obsolete ALE1PF05. Both relays are manufactured by Panasonic Electric Works and share identical core electrical specifications: 5VDC coil voltage, SPST-NO contact form, 16A contact rating, 63 Ohm coil resistance, and 80 mA coil current.

The ALZN5F05W carries active product status with ROHS3 compliance and cURus/VDE certifications. The substitute demonstrates enhanced performance characteristics including higher maximum switching voltage (440VAC vs. 277VAC), increased load capacity (7040VA vs. 4432VA), faster release time (5 ms vs. 20 ms), and extended operating temperature range (-40°C to 105°C vs. -40°C to 85°C). These improvements provide superior capability margins without introducing incompatibility with existing circuit designs.

The ALZN5F05W is packaged in trays and maintains through-hole PC pin termination identical to the original part, ensuring direct mechanical and electrical compatibility in PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5F05W directly replace the ALE1PF05 in existing designs?

A: Yes. The ALZN5F05W meets all critical electrical and mechanical specifications of the ALE1PF05. Coil voltage, contact form, current rating, coil resistance, and termination style are identical. The substitute is mechanically compatible with existing through-hole PCB layouts.

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

A: The ALZN5F05W provides enhanced performance: maximum switching voltage increases from 277VAC to 440VAC, load capacity increases from 4432VA to 7040VA, release time decreases from 20 ms to 5 ms, and operating temperature range extends to 105°C. These represent performance improvements, not deviations from the original specification.

Q: Are there packaging differences?

A: The ALE1PF05 packaging format is not specified in available data. The ALZN5F05W is supplied in trays. Both maintain identical through-hole PC pin termination for PCB mounting.

Q: What compliance certifications apply to the substitute?

A: The ALZN5F05W holds cURus and VDE certifications with ROHS3 compliance. The original ALE1PF05 held CSA, TUV, UR, and VDE certifications with RoHS compliance. Certification differences reflect product evolution and regional regulatory updates.

Q: Is the ALZN5F05W suitable for high-temperature applications?

A: The ALZN5F05W operates across -40°C to 105°C, extending the upper temperature limit by 20°C compared to the ALE1PF05 (-40°C to 85°C). This provides additional thermal margin for elevated ambient or self-heating conditions.

Q: What is the coil current requirement for both relays?

A: Both relays require 80 mA coil current at 5VDC, with 63 Ohm coil resistance. Drive circuit requirements remain identical.
