Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE110C-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Clamping (Max) @ Ipp: 159.6V maximum
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 axial configuration
• Type: Zener TVS diode

The identified substitute parts maintain the same reverse standoff voltage (94V) and peak pulse power rating (600W). However, substitute parts exhibit lower maximum clamping voltages (152V) compared to the original specification (159.6V), representing a tighter clamping characteristic. Both substitute parts are active products with current manufacturing status and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

P6KE110CA-B (Littelfuse Inc.) is the primary substitute for P6KE110C-B. Both components are manufactured by Littelfuse Inc., share identical reverse standoff voltage (94V) and peak pulse power ratings (600W), and maintain full RoHS3 compliance. The P6KE110CA-B is currently in active production status, ensuring long-term availability. The clamping voltage specification of 152V represents a 7.6V reduction from the original 159.6V, providing enhanced transient suppression characteristics. Operating temperature range (-55°C ~ 175°C) is identical to the original part.

P6KE110CA (Taiwan Semiconductor Corporation) serves as a secondary substitute option. This part maintains equivalent electrical performance with 94V reverse standoff voltage and 600W peak pulse power. The 152V clamping voltage matches the Littelfuse substitute. Taiwan Semiconductor Corporation's P6KE110CA is actively manufactured and RoHS3 compliant. Packaging is available in Tape & Reel format, suitable for automated assembly processes. Operating temperature range is not specified for this variant.

Both substitute parts are suitable for direct replacement in applications where the original P6KE110C-B is no longer available, provided circuit design accommodates the lower clamping voltage specification.

Frequently Asked Questions (FAQ)

Q: Can P6KE110CA-B directly replace P6KE110C-B in existing designs?

A: Yes. Both parts share the same reverse standoff voltage (94V), peak pulse power rating (600W), bidirectional channel configuration (1), and through-hole axial package format. The P6KE110CA-B exhibits a lower maximum clamping voltage (152V vs. 159.6V), which provides tighter voltage suppression and is compatible with applications designed for the original specification.

Q: What is the difference between P6KE110CA-B and P6KE110CA?

A: P6KE110CA-B is manufactured by Littelfuse Inc. in bulk packaging, while P6KE110CA is manufactured by Taiwan Semiconductor Corporation in Tape & Reel packaging. Both maintain identical electrical specifications: 94V reverse standoff voltage, 152V clamping voltage, and 600W peak pulse power. Selection depends on packaging requirements and supply chain preferences.

Q: Are there packaging differences between substitute parts and the original?

A: The original P6KE110C-B packaging format is not specified in available documentation. P6KE110CA-B is supplied in bulk packaging, while P6KE110CA is supplied in Tape & Reel format. Both maintain the same DO-204AC/DO-15 axial through-hole package configuration, ensuring mechanical and electrical compatibility.

Q: How does the clamping voltage difference affect circuit performance?

A: The substitute parts specify a maximum clamping voltage of 152V compared to the original 159.6V. This 7.6V reduction means transient voltages are suppressed to a lower threshold, providing enhanced protection. Applications must verify that downstream components tolerate the lower clamping voltage specification.

Q: What is the product status significance?

A: The original P6KE110C-B is classified as obsolete, indicating discontinued manufacturing. Both substitute parts are in active production status, ensuring reliable long-term availability and supply chain continuity for new designs and ongoing system support.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both P6KE110CA-B and P6KE110CA maintain full RoHS3 compliance, meeting environmental and regulatory requirements equivalent to the original P6KE110C-B specification.
