ALE73F24 Equivalent & Substitute Parts

Part Overview

The ALE73F24 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 alternatives necessary for ongoing system maintenance and new design implementations where this relay specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALE73F24 is determined by strict alignment with the following core electrical and mechanical parameters:

• Coil Voltage: Must be 24VDC
• Contact Configuration: Must be SPST-NO (1 Form A)
• Current Rating: Must be 16A minimum
• Maximum Switching Voltage: Must support 277VAC or higher
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin, Quick Connect - 0.187" (4.7mm)
• Coil Type: Must be Non Latching
• Contact Material: Must be Silver Tin Oxide (AgSnO)

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

Parameter Comparison

Engineering Selection Recommendations

The PCK-124D2M,000 is an active product from TE Connectivity Potter & Brumfield Relays and serves as a direct functional equivalent to the obsolete ALE73F24. Both relays share identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage. Both are certified to CSA, TUV, UR, and VDE standards and carry RoHS compliance status.

The PCK-124D2M,000 exhibits faster release time (10 ms versus 25 ms) and higher coil current draw (20.8 mA versus 8.3 mA) due to lower coil resistance (1.15 kOhms versus 2.88 kOhms). The operating temperature range of the TE Connectivity part is -30°C to 85°C, compared to -40°C to 85°C for the Panasonic part. These differences do not affect functional substitution in standard applications but should be evaluated against specific system requirements for temperature extremes and power consumption constraints.

Frequently Asked Questions (FAQ)

Q: Can the PCK-124D2M,000 be used as a direct replacement for the ALE73F24?

A: Yes. Both relays meet identical specifications for coil voltage (24VDC), contact form (SPST-NO), current rating (16A), switching voltage (277VAC), mounting type (through hole), and termination style (PC Pin, Quick Connect - 0.187"). Physical and electrical compatibility is confirmed.

Q: What are the differences between these two relays?

A: The primary differences are coil resistance (2.88 kOhms versus 1.15 kOhms), coil current (8.3 mA versus 20.8 mA), release time (25 ms versus 10 ms), and minimum operating temperature (-40°C versus -30°C). These differences do not affect substitution in standard applications.

Q: Does the lower coil resistance of the PCK-124D2M,000 affect circuit design?

A: The higher coil current requirement (20.8 mA versus 8.3 mA) must be accommodated by the driving circuit. Verify that the control circuit can supply the required current without exceeding component ratings.

Q: Are both relays RoHS compliant?

A: The ALE73F24 is RoHS compliant. The PCK-124D2M,000 has RoHS status listed as not applicable. Verify compliance requirements for your specific application.

Q: What is the impact of the faster release time in the PCK-124D2M,000?

A: The 10 ms release time (versus 25 ms) results in faster contact opening. This may affect timing-sensitive applications. Evaluate system requirements before substitution.

Q: Are the termination styles identical?

A: Yes. Both relays use PC Pin, Quick Connect - 0.187" (4.7mm) termination, ensuring mechanical and electrical compatibility in through-hole PCB applications.
