Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2106UATP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs waveforms)
• Hold current (Ih)
• Number of active elements
• Capacitance range
• Physical package and mounting configuration
• Supplier device package designation

The P2106UALTP qualifies as a direct substitute based on identical electrical characteristics and mechanical compatibility. The primary distinction is packaging format and product status, with P2106UALTP available in tube packaging and maintaining active production status.

Parameter Comparison

Engineering Selection Recommendations

The P2106UALTP is the direct functional equivalent for applications currently specified with P2106UATP. Selection between these parts should be based on the following factors:

Product Status: P2106UALTP maintains active production status with Littelfuse Inc., ensuring long-term availability and supply chain continuity. P2106UATP is obsolete and subject to inventory depletion.

Compliance Posture: P2106UALTP is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. P2106UATP is non-compliant with RoHS standards.

Packaging Consideration: P2106UALTP is supplied in tube packaging, which may require adjustment to existing procurement and assembly workflows if the original part was supplied in alternative packaging formats.

Electrical Equivalence: Both parts are electrically and mechanically identical across all specified parameters, permitting direct substitution without circuit redesign or performance impact.

Frequently Asked Questions (FAQ)

Q: Can P2106UALTP be used as a direct replacement for P2106UATP in existing designs?

A: Yes. P2106UALTP is electrically and mechanically equivalent to P2106UATP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and package configuration. Direct substitution is permissible without design modification.

Q: What is the primary reason to transition from P2106UATP to P2106UALTP?

A: P2106UATP is classified as obsolete, creating supply risk and potential unavailability. P2106UALTP is in active production status, ensuring reliable component sourcing and compliance with current regulatory standards.

Q: Are there compliance differences between these parts?

A: Yes. P2106UALTP is ROHS3 compliant and REACH unaffected, while P2106UATP is RoHS non-compliant. For applications subject to RoHS or REACH requirements, P2106UALTP is the required selection.

Q: Does packaging format affect electrical performance?

A: No. The tube packaging of P2106UALTP does not alter electrical characteristics or performance. Packaging differences are logistical only and do not impact circuit function or reliability.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both P2106UATP and P2106UALTP have MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints for storage or handling.

Q: What is the inventory status for P2106UALTP?

A: P2106UALTP has 1120 pieces in new original stock, providing immediate availability for procurement and production requirements.
