SB15100-TP Equivalent & Substitute Parts

Part Overview

The SB15100-TP is a through-hole rectifier diode rated for 15A continuous current in a DO-201AD axial package. Manufactured by Micro Commercial Co, this component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. The obsolete status requires engineers to evaluate active substitute components that maintain electrical and mechanical compatibility with existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the SB15100-TP are identified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Current rating: 15A minimum
• Through-hole mounting configuration
• Axial package geometry (DO-201AD or equivalent R-6 form factor)
• ROHS3 compliance
• MSL 1 rating

Mechanical Compatibility Criteria:

• Axial lead configuration for PCB insertion
• Physical dimensions compatible with DO-201AD footprint spacing

The 15SQ100 from SMC Diode Solutions meets these substitution criteria as an active product with identical current rating, through-hole mounting, axial package configuration, and equivalent compliance certifications.

Engineering Selection Recommendations

The 15SQ100 is the identified substitute for the obsolete SB15100-TP based on the following engineering factors:

Product Status Alignment: The 15SQ100 maintains active product status with current manufacturing support, addressing the obsolescence constraint of the original component.

Compliance Certification: Both components maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity in applications subject to these requirements.

Electrical and Mechanical Compatibility: The 15SQ100 provides equivalent 15A current handling capacity in a through-hole axial configuration. The R-6 package maintains physical compatibility with DO-201AD footprint requirements for axial lead spacing and PCB insertion.

Moisture Sensitivity: Both components carry MSL 1 rating, indicating unlimited shelf life and eliminating moisture-related handling constraints.

Selection of the 15SQ100 as a substitute component maintains functional equivalence while transitioning from an obsolete to an active product line.

Frequently Asked Questions (FAQ)

Q: Can the 15SQ100 be used as a direct replacement for the SB15100-TP in existing designs?

A: The 15SQ100 provides electrical and mechanical compatibility as a through-hole axial diode with 15A current rating. Both components share identical MSL 1 and ROHS3 compliance. Physical lead spacing in the R-6 package is compatible with DO-201AD footprint requirements for standard PCB insertion.

Q: What are the key differences between the SB15100-TP and 15SQ100?

A: The primary difference is product status: SB15100-TP is obsolete while 15SQ100 is active. The 15SQ100 is specified as a Schottky diode with 100V reverse voltage rating, 830mV forward voltage at 15A, and fast recovery characteristics. The SB15100-TP detailed electrical specifications are not provided in available documentation.

Q: Are there any compliance or certification differences between these components?

A: Both components maintain ROHS3 compliance, MSL 1 rating, and EAR99 export classification. No compliance divergence exists between the two parts.

Q: Does the R-6 package provide equivalent PCB mounting to the DO-201AD package?

A: Both packages utilize axial lead configuration for through-hole PCB insertion. The R-6 package maintains standard axial lead spacing compatible with DO-201AD footprint requirements.

Q: What is the inventory status for the 15SQ100 substitute?

A: The 15SQ100 is available with 7059 pieces in new original stock, providing supply continuity for designs transitioning from the obsolete SB15100-TP.
