AEV16012 Equivalent & Substitute Parts

Part Overview

The AEV16012 is an automotive SPST relay manufactured by Panasonic Electric Works, rated for 60A at 12VDC with chassis mount configuration and screw terminal termination. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and procurement continuity. The AEV series provides non-latching relay functionality suitable for automotive switching applications requiring high current capacity and reliable operation across extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AEV16012 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Mounting type: Chassis Mount
• Operating temperature range: -40°C ~ 80°C
• Moisture sensitivity level: 1 (Unlimited)
• REACH and ECCN compliance status

Allowable Variation Parameters:

• Contact rating (current): Equal to or greater than 60A
• Coil current: May vary within automotive relay design standards
• Switching voltage: Equal to or greater than 400VDC nominal
• Must operate/release voltages: Consistent with 12VDC coil design
• Operate/release times: Within automotive switching specifications
• Termination style: May differ (screw terminal to stud acceptable for equivalent function)
• Product status: Active status preferred for ongoing availability

The AEV18012W meets all mandatory criteria and exceeds current capacity specifications, qualifying as a direct substitute.

Engineering Selection Recommendations

The AEV18012W is the qualified substitute for the obsolete AEV16012. Selection is based on the following factors:

Product Status: The AEV18012W maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete AEV16012.

Compliance Alignment: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring regulatory consistency. The AEV18012W adds ROHS3 compliance, meeting current environmental standards.

Electrical Equivalence: The substitute maintains identical coil voltage (12VDC), contact form (SPST-NO), and switching characteristics (must operate at 9VDC, must release at 1VDC). Timing parameters (50ms operate, 30ms release) are identical.

Current Capacity Enhancement: The AEV18012W provides 80A contact rating versus the original 60A specification, with improved switching voltage capability (450VDC nominal versus 400VDC nominal). This represents a performance upgrade suitable for the original application.

Termination Consideration: The substitute uses stud termination instead of screw terminal. Circuit board or connector modifications may be required depending on existing installation configuration.

Frequently Asked Questions (FAQ)

Q: Can the AEV18012W directly replace the AEV16012 in existing designs?

A: The AEV18012W is electrically and functionally equivalent for all switching and coil parameters. Termination style differs (stud versus screw terminal), requiring mechanical interface verification before installation.

Q: What is the significance of the higher 80A rating on the substitute part?

A: The AEV18012W contact rating of 80A exceeds the original 60A specification. This provides additional current capacity margin and is fully compatible with circuits designed for 60A operation.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected and EAR99 classifications. The AEV18012W adds ROHS3 compliance certification, meeting current environmental requirements.

Q: Why does the substitute have lower coil current (353mA versus 415mA)?

A: Coil current variation reflects design optimization within the AEV series while maintaining identical 12VDC coil voltage and switching performance. Both values are within automotive relay design standards.

Q: What is the impact of the higher switching voltage rating (450VDC versus 400VDC)?

A: The increased switching voltage capability provides additional margin for transient protection and is fully compatible with applications designed for 400VDC nominal operation.

Q: Is packaging different between these parts?

A: The AEV16012 uses standard packaging, while the AEV18012W is supplied in tray packaging. This affects handling and storage but does not impact electrical performance.
