ALE1PF09 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The ALE1PF09 is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 9VDC coil and 16A contact rating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The ALE1PF09 operates at a maximum switching voltage of 277VAC with a coil resistance of 203 Ohms and is approved by CSA, TUV, UR, and VDE standards.

Substitute Part Grouping Explanation

Substitution of the ALE1PF09 is determined by strict equivalence across the following critical parameters:

Coil voltage: 9VDC (exact match required)
Contact form: SPST-NO (1 Form A) (exact match required)
Contact rating: 16A (exact match required)
Coil current: 44.4 mA (exact match required)
Coil resistance: 203 Ohms (exact match required)
Mounting type: Through Hole (exact match required)
Contact material: Silver Tin Oxide (AgSnO) (exact match required)
Termination style: PC Pin (exact match required)

The ALZN5F09W meets all critical substitution criteria. While this substitute demonstrates enhanced performance characteristics in switching voltage (440VAC vs. 277VAC), operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C), and response times, these improvements do not disqualify it as a functional equivalent. The substitute maintains identical coil specifications, contact configuration, and current rating.

Engineering Selection Recommendations

The ALZN5F09W is the designated substitute for the obsolete ALE1PF09. Both components are manufactured by Panasonic Electric Works and share identical electrical specifications for coil voltage, contact configuration, current rating, and coil resistance.

The ALZN5F09W carries active product status, ensuring ongoing availability and supply chain continuity. This substitute maintains RoHS compliance (ROHS3 vs. RoHS Compliant) and meets VDE certification requirements. The ALZN5F09W includes sealed flux protection, providing enhanced environmental protection compared to the original part.

The substitute demonstrates improved performance characteristics including higher maximum switching voltage (440VAC vs. 277VAC), faster response times (15ms operate vs. 20ms, 5ms release vs. 20ms), and extended operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C). These enhancements do not introduce compatibility issues and support operation in more demanding thermal environments.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5F09W directly replace the ALE1PF09 in existing applications?

A: Yes. Both relays share identical coil voltage (9VDC), contact form (SPST-NO), current rating (16A), coil current (44.4mA), and coil resistance (203 Ohms). The through-hole PC pin termination is identical. The ALZN5F09W is electrically and mechanically compatible for direct substitution.

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

A: The ALZN5F09W offers enhanced specifications: maximum switching voltage increases from 277VAC to 440VAC, operating temperature range extends from -40°C ~ 85°C to -40°C ~ 105°C, and response times improve (operate time 15ms vs. 20ms, release time 5ms vs. 20ms). The substitute includes sealed flux protection and carries active product status.

Q: Why is the ALE1PF09 classified as obsolete?

A: The ALE1PF09 has been discontinued by Panasonic Electric Works. The ALZN5F09W represents the current active equivalent within the product line.

Q: Are there packaging differences between these parts?

A: The ALE1PF09 is supplied with standard packaging, while the ALZN5F09W is supplied in tray packaging. Both maintain identical through-hole mounting and PC pin termination.

Q: Do both relays meet the same regulatory standards?

A: Both relays meet VDE certification. The ALE1PF09 carries CSA, TUV, UR, and VDE approvals, while the ALZN5F09W carries cURus and VDE approvals. Both are RoHS compliant and classified as EAR99 for export control purposes.

Q: What is the coil resistance for both relays?

A: Both the ALE1PF09 and ALZN5F09W have a coil resistance of 203 Ohms, ensuring identical electrical load characteristics in circuit applications.
