Key Parameters

Substitute Part Grouping Explanation

The AEVA1251 is identified as a manufacturer-recommended substitute for the AEV17012. Substitution is valid based on the following critical parameters:

• Coil Voltage & Current: Both parts operate at 12VDC with 500 mA coil current, ensuring direct electrical compatibility with existing drive circuits.
• Contact Form: Both maintain SPST-NO (1 Form A) configuration, preserving circuit topology.
• Switching Characteristics: Both parts share identical operate time (50 ms) and release time (30 ms), maintaining system timing requirements.
• Mounting & Termination: Both are chassis-mount relays, though termination differs (wire leads vs. screw terminal).
• Coil Power: Both consume 6W, matching power supply requirements.

The AEVA1251 provides enhanced performance through higher contact rating (250A vs. 200A) and increased switching voltage capability (500VDC vs. 450VDC), making it suitable for applications requiring greater margin or higher-voltage switching environments.

Engineering Selection Recommendations

The AEVA1251 is the manufacturer-recommended substitute for the AEV17012. Selection of the AEVA1251 is supported by:

• Product Status: The AEVA1251 maintains Active status, ensuring continued availability and manufacturing support, whereas the AEV17012 is designated "Not For New Designs."
• Regulatory Compliance: Both parts are ROHS3 Compliant and carry identical ECCN (EAR99) classification, maintaining compliance posture across supply chain transitions.
• Electrical Compatibility: Identical coil parameters (12VDC, 500 mA, 6W) and switching characteristics (50 ms operate, 30 ms release) ensure drop-in compatibility with existing control circuits.
• Performance Enhancement: The AEVA1251 provides higher contact current rating (250A vs. 200A) and increased switching voltage (500VDC vs. 450VDC), offering improved margin for high-current or high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the AEVA1251 directly replace the AEV17012 in existing designs?

A: Yes. Both relays share identical coil voltage (12VDC), coil current (500 mA), contact form (SPST-NO), and switching timing (50 ms operate, 30 ms release). The primary difference is termination style: the AEV17012 uses wire leads while the AEVA1251 uses screw terminals. Mechanical integration must account for this termination difference.

Q: What are the key differences between these two relays?

A: The AEVA1251 provides higher contact rating (250A vs. 200A), increased switching voltage (500VDC vs. 450VDC), and extended operating temperature range (-40°C to 85°C vs. -40°C to 80°C). The AEVA1251 is an active product, while the AEV17012 is not recommended for new designs.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 Compliant with identical ECCN classification (EAR99). No compliance barriers exist for substitution.

Q: Does packaging differ between these parts?

A: Yes. The AEV17012 is supplied in Bulk packaging, while the AEVA1251 is supplied in Tray packaging. This affects handling and storage but does not impact electrical or mechanical function.

Q: What is the coil resistance of the AEVA1251?

A: The AEVA1251 has a coil resistance of 24 Ohms, consistent with its 12VDC, 500 mA, 6W specification.
