P4KE110A-B Equivalent & Substitute Parts

Part Overview

The P4KE110A-B is an active Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This unidirectional zener diode operates with a reverse standoff voltage of 94V and provides clamping at 152V maximum, making it suitable for circuit protection in industrial and commercial electronics. The component is RoHS3 compliant and REACH unaffected, with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or packaging format requirements while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE110A-B are determined by strict equivalence across all critical electrical parameters and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 2.7A
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Package / Case: DO-204AL (DO-41), Axial
• Mounting Type: Through Hole
• Type: Zener, Unidirectional (1 channel)

Substitute parts may differ only in packaging format (Bulk versus Tape & Reel) and manufacturer identity, provided all electrical characteristics and mechanical dimensions remain within specification. The base product number P4KE110 identifies the electrical series, ensuring functional equivalence across approved substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE110A-B (Littelfuse Inc.) and P4KE110A (Taiwan Semiconductor Corporation) are active products with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

• Packaging format requirements: Bulk packaging for the Littelfuse variant versus Tape & Reel for the Taiwan Semiconductor variant
• Inventory availability and lead time considerations
• Compliance certifications: Both parts maintain RoHS3 compliance and REACH unaffected status
• Supplier qualification and procurement policies within your organization

No electrical performance difference exists between these parts. The choice is driven by supply chain logistics and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Are P4KE110A-B and P4KE110A electrically identical?

A: Yes. Both parts share identical electrical specifications including reverse standoff voltage (94V), breakdown voltage (105V minimum), clamping voltage (152V maximum), peak pulse current (2.7A), and peak pulse power (400W). Operating temperature range and all other electrical parameters are equivalent.

Q: What is the difference between these substitute parts?

A: The primary difference is packaging format. The P4KE110A-B is supplied in Bulk packaging, while the P4KE110A is supplied in Tape & Reel (TR) format. Both use the same DO-204AL (DO-41) axial through-hole package.

Q: Can I use P4KE110A in place of P4KE110A-B in my circuit?

A: Yes, provided your assembly process accommodates the Tape & Reel packaging format. The electrical performance and mechanical fit are identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both P4KE110A-B and P4KE110A are RoHS3 compliant and REACH unaffected.

Q: What does the base product number P4KE110 indicate?

A: The base product number P4KE110 identifies the electrical series and specifications. Variants with different suffixes (such as -B or -A) may indicate packaging or manufacturer differences, but electrical performance remains consistent within the series.

Q: Is there a performance difference between Littelfuse and Taiwan Semiconductor versions?

A: No. Both manufacturers produce parts to identical electrical and mechanical specifications for this part number. Selection is based on supply availability and packaging requirements, not performance.
