Key Parameters

Substitute Part Grouping Explanation

Substitution of the B84103S0001A010 is determined by the following critical parameters:

• Voltage Rating: 250VAC minimum
• Current Rating: 1A minimum filter current rating
• Connector Standard: IEC 320-C14 compatibility
• Filter Configuration: EMI/RFI filtering capability
• Termination: Quick connect (0.250" / 6.3mm) compatibility
• Regulatory Compliance: UL and CSA approvals

The B84776A0001A000 qualifies as a substitute based on matching these core electrical and mechanical parameters. Both components are manufactured by EPCOS – TDK Electronics, share IEC 320-C14 connector compatibility, and provide filtered power entry with equivalent voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

The B84776A0001A000 is the manufacturer-recommended substitute for the obsolete B84103S0001A010. Both components meet 250VAC, 1A filtered power entry requirements with IEC 320-C14 connectivity and quick connect termination.

The primary design difference is mounting configuration: the B84103S0001A010 is chassis mount, while the B84776A0001A000 is panel mount with flange. This distinction requires mechanical redesign of the enclosure or mounting bracket to accommodate the substitute.

The B84776A0001A000 carries active product status and maintains ROHS3 compliance. It includes expanded regulatory approvals (cUL, ENEC, UL) compared to the original part, and provides fuse holder integration with on-off switch functionality. These features enhance system-level EMI/RFI filtering and circuit protection.

Frequently Asked Questions (FAQ)

Q: Can the B84776A0001A000 directly replace the B84103S0001A010 without mechanical modification?

A: No. The B84103S0001A010 is chassis mount; the B84776A0001A000 is panel mount with flange. Mechanical redesign of the mounting interface is required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components are rated 250VAC, 1A filtered power entry with IEC 320-C14 connectors and quick connect termination. Both provide EMI/RFI filtering suitable for general-purpose applications.

Q: Does the B84776A0001A000 include a fuse?

A: The B84776A0001A000 accommodates a fuse (fuse not included). The original B84103S0001A010 specifications do not indicate fuse accommodation.
