Key Parameters

Substitute Part Grouping Explanation

The AEV18012W qualifies as a functional substitute for the AEV13012 based on the following substitution criteria:

Matching Parameters:

• Coil voltage: 12VDC (identical)
• Coil type: Non-latching (identical)
• Contact form: SPST-NO (1 Form A) (identical)
• Must operate voltage: 9 VDC (identical)
• Must release voltage: 1 VDC (identical)
• Operate time: 50 ms (identical)
• Release time: 30 ms (identical)
• Mounting type: Chassis mount (identical)
• Operating temperature range: -40°C ~ 80°C (identical)
• Moisture sensitivity level: 1 (Unlimited) (identical)
• REACH status: REACH Unaffected (identical)
• ECCN: EAR99 (identical)
• HTSUS: 8536.41.0050 (identical)

Allowable Differences:

• Contact rating: 80A (AEV18012W) vs. 30A (AEV13012) — higher current capacity is acceptable for applications requiring ≤30A
• Coil current: 353 mA (AEV18012W) vs. 415 mA (AEV13012) — lower coil current reduces power consumption
• Switching voltage: 450VDC (AEV18012W) vs. 400VDC (AEV13012) — higher switching voltage provides enhanced capability
• Termination style: Stud (AEV18012W) vs. Screw terminal (AEV13012) — requires circuit board or connector adaptation
• Packaging: Tray (AEV18012W) vs. standard (AEV13012) — affects handling and assembly processes
• Product status: Active (AEV18012W) vs. Obsolete (AEV13012) — ensures long-term availability

Parameter Comparison

Engineering Selection Recommendations

The AEV18012W is suitable as a direct substitute for the AEV13012 in applications where the following conditions are met:

• Circuit design accommodates the stud termination configuration of the AEV18012W, or appropriate connector adaptation is implemented
• The 80A contact rating of the AEV18012W meets or exceeds the application's current requirements
• The lower coil current (353 mA vs. 415 mA) is compatible with the existing coil drive circuit
• The higher switching voltage rating (450VDC vs. 400VDC) does not conflict with application specifications

The AEV18012W is classified as Active product status, ensuring availability for procurement and long-term supply chain continuity. Both parts maintain identical REACH and ECCN compliance classifications, supporting regulatory requirements for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the AEV18012W replace the AEV13012 in existing designs?

A: The AEV18012W is functionally compatible with the AEV13012 for applications operating at or below 30A. The primary consideration is termination style: the AEV18012W uses stud termination instead of screw terminals, requiring circuit board or connector modifications.

Q: What is the significance of the higher 80A contact rating on the AEV18012W?

A: The 80A contact rating provides increased current-carrying capacity. For applications requiring only 30A, this represents a design margin that does not negatively impact performance. The relay will operate identically within the 30A specification range.

Q: Does the lower coil current of the AEV18012W affect circuit design?

A: The AEV18012W requires 353 mA coil current compared to 415 mA for the AEV13012. This reduction decreases power consumption in the coil drive circuit. Existing drive circuits designed for 415 mA will operate the AEV18012W without modification, as the lower current requirement is within the design margin.

Q: Are there packaging differences between these parts?

A: The AEV13012 uses standard packaging, while the AEV18012W is supplied in tray packaging. This affects handling, storage, and assembly processes but does not impact electrical or mechanical performance.

Q: Why is the AEV13012 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The AEV18012W, classified as Active, ensures continued availability and is the recommended substitute for new designs and ongoing production support.

Q: Are both parts compliant with automotive regulatory requirements?

A: Both the AEV13012 and AEV18012W maintain identical REACH Unaffected status and EAR99 ECCN classification, confirming compliance with applicable automotive regulatory frameworks.
