AEP16024 Equivalent & Substitute Parts

Part Overview

The AEP16024 is a general purpose relay manufactured by Panasonic Electric Works, configured as a single-pole single-throw normally open (SPST-NO) contact form with a 24VDC coil. This chassis mount relay is rated for 60A continuous current switching at 277VAC or 400VDC nominal switching voltage, with a maximum switching capacity of 16620VA. The part is currently obsolete, making identification of compatible substitute components essential for system maintenance and design continuity.

Substitute Part Grouping Explanation

The AEP16024 can be substituted with the AEV18024W based on the following critical parameters that define functional equivalence:

Core Compatibility Parameters:

• Coil voltage: Both operate at 24VDC
• Contact form: Both are SPST-NO (1 Form A) configuration
• Coil type: Both are non-latching
• Mounting type: Both are chassis mount
• Operating temperature range: Both operate across -40°C ~ 80°C
• Must operate and release voltages: Identical at 18 VDC and 2 VDC respectively
• Switching timing: Both have 50 ms operate time and 30 ms release time
• Manufacturer: Both are Panasonic Electric Works products

Differences in Substitute: The AEV18024W provides enhanced current rating (80A versus 60A), higher switching voltage capability (450VDC nominal versus 400VDC), and uses stud termination instead of screw terminal. These differences represent improvements in electrical capacity while maintaining functional compatibility for the core relay operation.

Parameter Comparison

Engineering Selection Recommendations

The AEV18024W is the designated substitute for the obsolete AEP16024. Selection of this substitute is supported by the following engineering factors:

Product Status: The AEP16024 is obsolete, while the AEV18024W maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring no change in regulatory or export control requirements.

Functional Equivalence: The substitute maintains all critical operational parameters including coil voltage, contact configuration, timing characteristics, and temperature operating range. The enhanced current rating (80A versus 60A) and switching voltage capability (450VDC versus 400VDC) of the substitute provide additional margin without compromising compatibility.

Coil Efficiency: The AEV18024W operates at lower coil current (176 mA versus 208 mA), resulting in reduced power consumption and heat generation during operation.

Mechanical Compatibility: Both relays are chassis mount configurations. The termination style difference (stud versus screw terminal) requires verification of connection compatibility within the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the AEV18024W directly replace the AEP16024 in existing applications?

A: The AEV18024W is functionally equivalent for relay operation based on matching coil voltage, contact form, timing, and temperature range. However, the termination style differs (stud versus screw terminal), requiring verification that connection hardware and circuit board layout accommodate the substitute's terminal configuration.

Q: What is the significance of the higher current rating in the AEV18024W?

A: The AEV18024W is rated for 80A continuous current versus the AEP16024's 60A rating. This represents an increase in electrical capacity. Applications operating at or below 60A will function identically with either part. Applications requiring current capacity between 60A and 80A can only be served by the substitute.

Q: Are there compliance or certification differences between these parts?

A: Both parts share identical REACH and ECCN classifications. The AEP16024 carries cURus approval, while the AEV18024W is RoHS3 compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: How does the lower coil current of the AEV18024W affect circuit design?

A: The AEV18024W requires 176 mA coil current compared to the AEP16024's 208 mA. This 32 mA reduction decreases power dissipation in the coil drive circuit. Existing drive circuits designed for 208 mA will operate the substitute without modification, as the lower current requirement represents a reduced load condition.

Q: What packaging considerations apply to the substitute?

A: The AEP16024 is specified with dash packaging notation, while the AEV18024W is supplied in bulk packaging. Verify that bulk packaging meets procurement and handling requirements for your application.
