APE10018 Equivalent & Substitute Parts

Part Overview

The APE10018 is a general purpose relay manufactured by Panasonic Electric Works, configured as a single-pole single-throw normally open (SPST-NO) device with an 18VDC coil and 6A contact rating. This through-hole mounted relay is designed for applications requiring reliable switching at 250VAC maximum. The APE10018 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APE10018 is based on the following critical parameters that must remain constant:

• Coil voltage: 18VDC
• Contact configuration: SPST-NO (1 Form A)
• Contact current rating: 6 A minimum
• Switching voltage: 250VAC maximum
• Mounting type: Through hole
• Termination style: PC pin
• Operating temperature range: -40°C to 85°C minimum

The APF10218 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. Both relays share identical coil voltage, contact form, current rating, switching voltage, mounting configuration, and operating temperature specifications. The APF10218 represents an active product status alternative to the obsolete APE10018.

Parameter Comparison

Engineering Selection Recommendations

The APF10218 is the appropriate substitute for the obsolete APE10018 based on the following factors:

• All critical electrical parameters match exactly: coil voltage, contact configuration, current rating, and switching voltage
• Mechanical compatibility is confirmed through identical mounting type and termination style
• Operating temperature range is identical, ensuring thermal performance equivalence
• The APF10218 maintains active product status, ensuring long-term availability and supply chain continuity
• The APF10218 is RoHS compliant, meeting current environmental and regulatory requirements
• Coil current variation (9 mA to 9.4 mA) is within acceptable tolerance for general purpose relay applications
• Contact material differs (Silver Alloy to Silver Nickel), but both materials are standard for 6A switching applications at 250VAC

Frequently Asked Questions (FAQ)

Q: Can the APF10218 be used as a direct replacement for the APE10018 in existing designs?

A: Yes. The APF10218 maintains identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage. Through-hole mounting and PC pin termination are identical, allowing direct PCB substitution without design modification.

Q: What is the significance of the contact material change from Silver Alloy to Silver Nickel?

A: Both Silver Alloy and Silver Nickel are standard contact materials for general purpose relays rated at 6A and 250VAC. The Silver Nickel composition in the APF10218 provides equivalent switching performance and contact reliability for this application class.

Q: Why is the APE10018 listed as obsolete?

A: The APE10018 has been discontinued by Panasonic Electric Works. The APF10218 represents the active product line continuation with equivalent specifications.

Q: Does the slight increase in coil current (9 mA to 9.4 mA) affect circuit design?

A: The 0.4 mA increase is within normal manufacturing tolerance for relay coils and does not require circuit redesign. Both relays maintain 1.9 kOhm coil resistance and identical operate/release timing.

Q: Is the APF10218 available in the same packaging as the APE10018?

A: The APF10218 is supplied in tube packaging. Verify packaging requirements for your application, as the original APE10018 packaging specification was not provided.

Q: What compliance advantages does the APF10218 offer?

A: The APF10218 is RoHS compliant, meeting current environmental regulations. This ensures compatibility with modern procurement standards and regulatory requirements for electronic components.
