APE10118 Equivalent & Substitute Parts

Part Overview

The APE10118 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 APE10118 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APE10118 is determined by strict equivalence across the following critical parameters:

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

The APF10318 satisfies all substitution criteria. Both relays share identical contact form, coil voltage, current rating, switching voltage, mounting configuration, and termination style. Operating temperature ranges are identical. The APF10318 is classified as active product status, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The APF10318 is the direct functional equivalent for APE10118 replacement applications. Selection is based on the following factors:

Product Status: The APE10118 is obsolete, while APF10318 is active. Active product status ensures supply chain continuity, technical support availability, and manufacturing consistency.

Regulatory Compliance: APF10318 carries RoHS compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Electrical Equivalence: Both relays operate identically across all critical switching parameters. The APF10318 coil current specification of 9.4 mA versus 9 mA for APE10118 represents a 4.4% variance within acceptable engineering tolerance for relay coil design. The must-operate voltage difference of 12.6 VDC (APF10318) versus 11.88 VDC (APE10118) reflects normal manufacturing variation in relay calibration and does not affect functional compatibility in standard 18VDC supply applications.

Contact Material Enhancement: APF10318 employs silver-nickel and gold contact materials compared to silver alloy in APE10118, providing improved contact reliability and extended operational life.

Mechanical Compatibility: Identical through-hole mounting and PC pin termination ensure direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can APF10318 directly replace APE10118 in existing circuit boards?

A: Yes. Both relays share identical mounting type (through hole), termination style (PC pin), coil voltage (18VDC), contact configuration (SPST-NO), and current rating (6A). No PCB modification is required.

Q: What is the significance of the coil current difference between APE10118 (9 mA) and APF10318 (9.4 mA)?

A: The 0.4 mA difference represents normal manufacturing tolerance in relay coil design. Both values fall within acceptable operating parameters for 18VDC supply circuits. This variance does not affect circuit functionality or component selection.

Q: Why does APF10318 have a higher must-operate voltage (12.6 VDC) than APE10118 (11.88 VDC)?

A: This difference reflects manufacturing calibration variation between relay series. In applications with stable 18VDC supply, both relays operate reliably. For circuits with marginal voltage conditions below 12.6 VDC, APE10118 specifications should be verified against actual supply voltage.

Q: What packaging differences exist between these relays?

A: APE10118 packaging is not specified in available documentation. APF10318 is supplied in tube packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Is APF10318 RoHS compliant?

A: Yes. APF10318 is RoHS compliant, meeting current environmental regulations for electronic component manufacturing. APE10118 RoHS status is not specified.

Q: Are the contact materials interchangeable?

A: Yes. APE10118 uses silver alloy contacts while APF10318 uses silver-nickel and gold contacts. The APF10318 contact material composition provides enhanced reliability and is fully compatible with standard relay switching applications.

Q: What is the operating temperature range for both relays?

A: Both APE10118 and APF10318 operate across -40°C to 85°C, ensuring compatibility across industrial and commercial temperature environments.
