P2103AB60 Equivalent & Substitute Parts

Part Overview

The P2103AB60 is a 170V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a 3-SIP through-hole package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2103AB60 is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor product line. The critical parameters governing substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current handling (both 8/20µs and 10/1000µs waveforms)
• Hold current specification
• Physical package configuration (3-SIP, TO-220 Modified)
• Element count and capacitance values

The P2103ABL60 meets all these criteria as a direct substitute, maintaining identical electrical performance while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The P2103ABL60 is the direct substitute for the obsolete P2103AB60. Both components are manufactured by Littelfuse Inc. and provide identical electrical performance across all specified parameters. The primary distinction is product lifecycle status: P2103AB60 is obsolete while P2103ABL60 is active.

For new designs and ongoing system support, P2103ABL60 is the appropriate selection. This part offers the additional advantage of ROHS3 compliance, whereas the original P2103AB60 is RoHS non-compliant. Both components share identical moisture sensitivity classification and export control designations.

Frequently Asked Questions (FAQ)

Q: Can P2103ABL60 be used as a direct replacement for P2103AB60?

A: Yes. The P2103ABL60 provides identical electrical specifications including voltage ratings (250V breakover, 170V off-state, 8V on-state), peak pulse current (250A at 8/20µs, 80A at 10/1000µs), hold current (150mA), and physical package configuration (3-SIP, TO-220 Modified). All critical parameters match exactly.

Q: What is the difference between P2103AB60 and P2103ABL60?

A: The components are electrically and mechanically identical. The differences are: P2103AB60 is obsolete while P2103ABL60 is active; P2103AB60 is RoHS non-compliant while P2103ABL60 is ROHS3 compliant; P2103AB60 uses tape packaging while P2103ABL60 uses bulk packaging.

Q: Are there any compatibility concerns when substituting P2103ABL60 for P2103AB60?

A: No compatibility concerns exist. The 3-SIP package configuration, TO-220 Modified supplier package, and all electrical parameters are identical. PCB layout and thermal management requirements remain unchanged.

Q: Does the packaging format difference affect circuit performance?

A: No. The packaging format difference (tape versus bulk) relates only to supply and handling. The component itself, its electrical characteristics, and physical dimensions remain identical.

Q: Is P2103ABL60 suitable for new designs?

A: Yes. P2103ABL60 is the active product in the SIDACtor® series for this specification. It is the recommended choice for new designs requiring 170V off-state, 250A peak pulse TVS thyristor functionality.
