PE890203 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The PE890203 is an AC power entry connector module manufactured by Curtis Industries, designed as a receptacle with male blades conforming to the IEC 320-C14 standard. This filtered power entry module is intended for panel-mount applications requiring EMI/RFI filtering, on-off switching, and dual fuse protection in commercial environments. The part is currently active in production with 1,028 units in stock. Substitute parts may be required due to supply constraints, regional availability, or specific application requirements for alternative termination methods or mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE890203 is determined by strict alignment with the following core parameters:

• Connector Standard: IEC 320-C14 receptacle configuration with male blades
• Electrical Specifications: 250VAC rated voltage and 3-position contact arrangement
• Filtering: Commercial-grade EMI/RFI filtering capability
• Switching & Protection: Integrated on-off switch with dual fuse holder accommodation
• Mounting Configuration: Panel-mount with flange design
• Compliance: ROHS3 compliance and recognized approval agency certifications (CE, CSA, UL, VDE)

The substitute part FN388-4-22 meets these core substitution criteria. Variations in termination method (solder eyelet vs. quick connect), panel thickness accommodation, and ingress protection rating do not disqualify substitution when the primary electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both PE890203 and FN388-4-22 are active production parts with ROHS3 compliance and recognized regulatory approvals. Selection between these parts should be based on:

PE890203 (Curtis Industries): Suitable for applications requiring quick-connect termination with fixed panel cutout dimensions (28.50mm x 55.90mm). Approved by CE, CSA, TUV, and UL.

FN388-4-22 (Schaffner EMC Inc.): Suitable for applications requiring solder eyelet termination with flexible panel thickness accommodation (0.79mm to 3.20mm). Supports front or rear side mounting. Approved by CSA, UL, and VDE. Includes IP40 ingress protection rating.

Both parts satisfy the core IEC 320-C14 receptacle interface, 250VAC voltage class, 3-position contact arrangement, commercial EMI/RFI filtering, on-off switching, and dual fuse holder requirements. Termination method and panel mounting flexibility are the primary differentiators.

Frequently Asked Questions (FAQ)

Q: Can FN388-4-22 directly replace PE890203 in existing designs?

A: Direct replacement depends on termination compatibility. PE890203 uses quick-connect terminals (0.110" / 2.8mm), while FN388-4-22 uses solder eyelet termination. If the PCB or wiring harness is designed for quick-connect, FN388-4-22 requires rework. If solder eyelet termination is acceptable, FN388-4-22 is electrically and mechanically compatible.

Q: Are there voltage or current rating differences between these parts?

A: PE890203 specifies 3A at 250VAC for the appliance inlet. FN388-4-22 specifies 4A at the filter stage. Both parts conform to IEC 320-C14 standard requirements. Verify application current draw against the applicable rating.

Q: What is the significance of the panel thickness accommodation difference?

A: PE890203 does not specify panel thickness limits. FN388-4-22 accommodates panel thickness from 0.79mm to 3.20mm (0.031" to 0.126"). If panel thickness falls outside this range, FN388-4-22 may not mount properly.

Q: Do both parts include fuses?

A: Neither part includes fuses. Both accommodate dual fuse holders (twin fused configuration). Fuses must be sourced separately and installed by the end user.

Q: Are there approval agency differences that affect substitution?

A: PE890203 carries CE, CSA, TUV, and UL approvals. FN388-4-22 carries CSA, UL, and VDE approvals. Both include UL and CSA certifications. If TUE or CE marking is mandatory for the application, PE890203 is the required choice.

Q: What does the IP40 ingress protection rating on FN388-4-22 indicate?

A: IP40 indicates protection against solid objects larger than 1mm and no protection against water ingress. PE890203 does not specify an ingress protection rating. If environmental sealing is critical, FN388-4-22 provides documented protection.
