ALE12F24 Equivalent & Substitute Parts

Part Overview

The ALE12F24 is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with a 24VDC coil. This through-hole mounted relay is rated for 16A at 277VAC maximum switching voltage and is designed for non-latching applications. The part is currently obsolete, making identification of functionally equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALE12F24 is determined by strict alignment of the following parameters:

• Coil voltage: 24VDC (exact match required)
• Contact configuration: SPST-NO (1 Form A) (exact match required)
• Contact current rating: 16 A (exact match required)
• Maximum switching voltage: 277VAC or higher (equal or greater acceptable)
• Mounting type: Through hole (exact match required)
• Termination style: PC Pin, Quick Connect - 0.187" (4.7mm) (exact match required)
• Coil type: Non-latching (exact match required)
• Contact material: Silver Tin Oxide (AgSnO) (exact match required)
• Coil insulation class: Class F (exact match required)

The PCK-124D2M,000 from TE Connectivity Potter & Brumfield Relays meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The PCK-124D2M,000 is a direct functional equivalent to the ALE12F24. Both relays share identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage. The substitute part is currently in active production status, ensuring availability for new designs and replacement applications.

The ALE12F24 carries CSA, TUV, UR, and VDE approvals with RoHS compliance. The PCK-124D2M,000 is not marked as RoHS compliant in available documentation. For applications requiring RoHS certification, compliance status must be verified with the manufacturer.

The operating temperature range of the ALE12F24 extends to -40°C, while the PCK-124D2M,000 operates from -30°C. For applications requiring operation below -30°C, the original part specification must be maintained.

Frequently Asked Questions (FAQ)

Q: Can the PCK-124D2M,000 be used as a direct replacement for the ALE12F24 in existing designs?

A: Yes, the PCK-124D2M,000 meets all critical electrical and mechanical parameters. Both relays feature identical 24VDC coil voltage, SPST-NO contact configuration, 16A current rating, 277VAC maximum switching voltage, and PC Pin Quick Connect termination. Physical mounting and electrical performance are compatible.

Q: What are the differences between these two relays?

A: The primary differences are coil current (16.7 mA vs. 20.8 mA), coil resistance (1.44 kOhms vs. 1.15 kOhms), release time (20 ms vs. 10 ms), and operating temperature range (-40°C to 85°C vs. -30°C to 85°C). The substitute part has faster release time and slightly higher coil current draw.

Q: Are there any compliance or certification differences?

A: The ALE12F24 carries CSA, TUV, UR, and VDE approvals and is RoHS compliant. The PCK-124D2M,000 RoHS status is not applicable per available documentation. Applications requiring specific regulatory certifications should verify compliance with the substitute manufacturer.

Q: Will the higher coil current of the PCK-124D2M,000 affect circuit design?

A: The coil current difference (16.7 mA vs. 20.8 mA) is approximately 25% higher. Existing driver circuits must be evaluated to confirm adequate current supply capability. The lower coil resistance of the substitute part results in this increased current draw at 24VDC.

Q: Is the faster release time of the PCK-124D2M,000 a concern?

A: The substitute part releases in 10 ms compared to 20 ms for the original. For applications where release time is critical to system timing, this difference must be evaluated against circuit requirements.
