Key Parameters

Substitute Part Grouping Explanation

Substitution of the A2106UA6TP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover (80V, 250V), Off-State (50V, 170V), and On-State (8V) must match exactly
• Current specifications: Peak pulse current (8/20µs and 10/1000µs) and hold current must be identical
• Element count: 6 elements required
• Capacitance range: 30pF to 60pF
• Package configuration: 6-SMD Gull Wing surface mount only
• Supplier device package: Modified MS-013

The A2106UA6LTP meets all these criteria and is classified as a direct manufacturer equivalent with identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The A2106UA6LTP is the direct equivalent substitute for the obsolete A2106UA6TP. Both components share identical electrical characteristics and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The primary distinction between these parts is product status and regulatory compliance. The A2106UA6LTP is currently in active production status, whereas the A2106UA6TP is obsolete. Additionally, the A2106UA6LTP carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and manufacturing operations. The A2106UA6TP is RoHS non-compliant.

Both components maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), ECCN designation (EAR99), and HTSUS code (8541.30.0080), indicating equivalent handling, export, and tariff classification requirements.

Frequently Asked Questions (FAQ)

Q: Can the A2106UA6LTP be used as a direct replacement for the A2106UA6TP in existing designs?

A: Yes. The A2106UA6LTP is electrically and mechanically identical to the A2106UA6TP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substituting the A2106UA6TP?

A: The A2106UA6TP is classified as obsolete. The A2106UA6LTP provides continued access to equivalent SIDACtor® TVS thyristor functionality from active inventory.

Q: Are there packaging differences between these parts?

A: Both components use identical 6-SMD Gull Wing surface mount packaging with Modified MS-013 supplier device package designation. The A2106UA6LTP is supplied in Tube packaging, while the A2106UA6TP packaging specification was not provided. This does not affect electrical or mechanical compatibility.

Q: Does the A2106UA6LTP meet current regulatory requirements?

A: Yes. The A2106UA6LTP carries ROHS3 compliance certification, meeting current environmental regulations. The A2106UA6TP is RoHS non-compliant. Both components share identical MSL, ECCN, and HTSUS classifications.

Q: Are the electrical specifications identical between these parts?

A: Yes. Breakover voltage (80V, 250V), off-state voltage (50V, 170V), on-state voltage (8V), peak pulse current (150A at 8/20µs, 45A at 10/1000µs), hold current (150mA), element count (6), and capacitance (30pF, 60pF) are identical across both components.
