FC68145S Equivalent & Substitute Parts

Part Overview

The FC68145S is an SMD socket barrel connector jack manufactured by CLIFF Electronic Components Ltd, designed for power delivery applications. This surface mount connector features a 1.30mm ID (0.051") and 3.70mm OD (0.146") mating diameter, rated for 12V at 1A with a single internal switch and board guide feature. The part is currently active in production with 846 units in stock. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where dimensional or electrical specifications allow direct replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for barrel connector jacks is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

• Mating diameter match: 1.30mm ID (0.051") and 3.70mm OD (0.146") are industry-recognized standard dimensions for this connector class
• Contact configuration: 2 Conductors, 3 Contacts with single internal switch
• Mounting technology: Surface mount solder termination
• Connector gender and type: Male jack configuration
• Compliance certifications: ROHS3 and REACH status

The substitute part PJ-075DH-SMT-TR (CUI Devices) meets these core mechanical and electrical compatibility criteria. While the substitute exhibits higher voltage and current ratings (24VDC, 4.6A versus 12V, 1A), these represent enhanced performance margins suitable for applications within the FC68145S operating envelope. The substitute's right-angle mounting orientation and enhanced housing material (Polyamide PA6T) provide design flexibility for space-constrained layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the FC68145S and PJ-075DH-SMT-TR maintain active product status with full ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring long-term availability and environmental regulatory alignment. Selection between these parts should be based on application-specific requirements:

The FC68145S is appropriate for applications requiring straight-mount surface mount orientation with 12V, 1A power delivery specifications.

The PJ-075DH-SMT-TR is suitable for designs requiring right-angle mounting geometry, higher voltage tolerance (24VDC), and increased current capacity (4.6A). The enhanced housing material (PA6T) provides improved thermal and mechanical performance in demanding environments.

Both parts share identical contact configuration (2 Conductors, 3 Contacts) and single-switch internal architecture, ensuring functional compatibility within the specified electrical envelope.

Frequently Asked Questions (FAQ)

Q: Can PJ-075DH-SMT-TR directly replace FC68145S in existing designs?

A: Direct mechanical and electrical substitution is supported. The mating diameter (1.30mm ID) is identical, contact configuration matches (2 Conductors, 3 Contacts), and both employ single-switch architecture. The primary design consideration is the right-angle mounting orientation of the substitute, which requires PCB layout modification. The substitute's higher voltage and current ratings do not create compatibility issues for applications operating within FC68145S specifications.

Q: What is the significance of the OD (outer diameter) difference between the parts?

A: The FC68145S specifies 3.70mm OD while the PJ-075DH-SMT-TR specifies 3.40mm OD. Both dimensions fall within the industry-recognized 1.30mm ID barrel connector class. The OD difference reflects manufacturing tolerance and design variation between manufacturers. Mating compatibility is determined by the inner diameter (ID) specification, which is identical at 1.30mm (0.051").

Q: Are there packaging differences between these parts?

A: Yes. The FC68145S is supplied in Bag packaging, while the PJ-075DH-SMT-TR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly operations and may require different handling procedures than bag packaging.

Q: What is the difference between straight-mount and right-angle mounting?

A: The FC68145S features straight-mount orientation, where the connector axis is perpendicular to the PCB surface. The PJ-075DH-SMT-TR features right-angle mounting, where the connector axis is parallel to the PCB surface. Right-angle mounting is used in space-constrained designs where vertical clearance is limited.

Q: Do both parts support the same current and voltage specifications?

A: The FC68145S is rated for 12V at 1A. The PJ-075DH-SMT-TR is rated for 24VDC at 4.6A. The substitute part supports higher electrical specifications, making it suitable for applications requiring the FC68145S ratings. Applications requiring the full 24VDC, 4.6A capability of the substitute should verify that connected components support these specifications.
