FC68148 Barrel Connector Jack - Equivalent & Substitute Parts

Part Overview

The FC68148 is an active, through-hole, right-angle power barrel connector jack manufactured by CLIFF Electronic Components Ltd. This 2.1mm ID connector is designed for DC power applications with a 12VDC rating and 5A current capacity. The connector features a single normally closed internal switch, solder eyelet termination, and gold-plated brass contacts housed in glass-filled PBT material.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for barrel connector jacks is determined by the following critical parameters:

• Connector Type & Gender: Must be Jack (Male) configuration
• Mounting Type: Must be Through Hole, Right Angle
• Internal Switch Configuration: Must include Single Switch, Normally Closed
• Termination Method: Must be Solder Eyelet(s)
• Electrical Compatibility: Voltage and current ratings must meet or exceed application requirements
• Physical Dimensions: Actual diameter specifications must be compatible with mating plug geometry
• Contact Material & Plating: Must support equivalent signal integrity and environmental performance
• Regulatory Compliance: Must maintain ROHS3 compliance and equivalent certifications

The PJ-002A from CUI Devices meets the core structural and functional requirements as a substitute part, with the following considerations documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Both the FC68148 and PJ-002A are active products with ROHS3 compliance and equivalent regulatory status (REACH Unaffected, ECCN EAR99, HTSUS 8536.69.4040).

The FC68148 is specified for 12VDC at 5A with gold-plated contacts and glass-filled PBT housing. The PJ-002A operates at 24VDC with a 2.5A current rating and tin-plated contacts in standard PBT housing.

Selection between these parts depends on application-specific electrical requirements. The FC68148 supports higher current capacity (5A vs. 2.5A), while the PJ-002A supports higher voltage (24VDC vs. 12VDC). Physical diameter variations exist between the two connectors and must be verified against mating plug specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Can the PJ-002A replace the FC68148 in all applications?

A: Substitution is valid only when the application voltage does not exceed 24VDC and current requirements do not exceed 2.5A. The physical diameter differences (OD: 6.30mm vs. 5.50mm) must be verified against the mating plug to ensure mechanical compatibility.

Q: What is the significance of the contact plating difference (gold vs. tin)?

A: Gold plating (FC68148) provides enhanced corrosion resistance and lower contact resistance over extended service life. Tin plating (PJ-002A) is suitable for standard applications but may exhibit higher contact resistance in high-humidity or corrosive environments. Selection depends on environmental exposure and signal integrity requirements.

Q: Are both connectors suitable for the same PCB footprint?

A: Both connectors use through-hole, right-angle mounting with solder eyelet termination. However, the outer diameter difference (6.30mm vs. 5.50mm) may affect PCB layout spacing. Verify mechanical clearance before substitution.

Q: Do both parts have the same internal switch configuration?

A: Yes. Both the FC68148 and PJ-002A feature a single normally closed internal switch with identical contact configuration (2 Conductors, 3 Contacts).

Q: What is the inventory status for these parts?

A: FC68148 has 651 pieces in stock. PJ-002A has 40,031 pieces in stock. Both are active products available for immediate procurement.
