5KP7.0C-B Equivalent & Substitute Parts

Part Overview

The 5KP7.0C-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This component features a 7V reverse standoff voltage and 5000W peak pulse power rating in a P600 axial through-hole package. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP7.0C-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Clamping (Max) @ Ipp: within acceptable tolerance range
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. Variations in clamping voltage and peak pulse current are within the operational tolerance of the TVS diode category for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5KP7.0CA, 5KP7.0CA-B, and 5KP7.0CE3/TR13) are classified as active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete 5KP7.0C-B.

The 5KP7.0CA and 5KP7.0CA-B are direct Littelfuse equivalents with identical electrical specifications and differ only in packaging format (Tape & Reel versus Bulk). Both maintain ROHS3 compliance and REACH unaffected status.

The 5KP7.0CE3/TR13 is a Microchip Technology alternative that meets all core substitution criteria. The clamping voltage specification of 13.3V represents a minor variation within acceptable TVS diode tolerance ranges for general-purpose applications, while peak pulse current is 376A compared to 425A in the Littelfuse alternatives.

Selection between these substitutes should be based on packaging requirements, supplier availability, and procurement lead times rather than electrical performance, as all three maintain functional equivalence for the 5KP7.0C-B application.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.0CA directly replace the 5KP7.0C-B in existing designs?

A: Yes. The 5KP7.0CA maintains identical reverse standoff voltage (7V), peak pulse power (5000W), operating temperature range (-55°C ~ 175°C), and P600 axial through-hole package specifications. The primary difference is product status (active versus obsolete) and packaging format.

Q: What is the difference between 5KP7.0CA and 5KP7.0CA-B?

A: Both parts are electrically identical Littelfuse TVS diodes with 7V standoff voltage and 5000W peak pulse power. The difference is packaging: 5KP7.0CA is supplied in Tape & Reel format, while 5KP7.0CA-B is supplied in Bulk packaging. Selection depends on assembly process requirements and order quantities.

Q: Is the Microchip 5KP7.0CE3/TR13 a suitable substitute?

A: Yes. The 5KP7.0CE3/TR13 meets all core substitution criteria: 7V reverse standoff voltage, 5000W peak pulse power, P600 axial through-hole package, and -55°C ~ 175°C operating temperature range. The clamping voltage of 13.3V and peak pulse current of 376A represent minor variations within TVS diode tolerance specifications for general-purpose transient protection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (5KP7.0CA, 5KP7.0CA-B, and 5KP7.0CE3/TR13) are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original 5KP7.0C-B.

Q: What packaging options are available for the 5KP7.0C-B replacement?

A: The 5KP7.0CA is available in Tape & Reel (TR) packaging for automated assembly processes. The 5KP7.0CA-B is available in Bulk packaging for manual assembly or lower-volume applications. The 5KP7.0CE3/TR13 is supplied in Tape & Reel format.

Q: Can I use these substitutes in new designs?

A: Yes. All three substitute parts are active products with current manufacturing status, making them suitable for both replacement in existing designs and implementation in new designs. The active product status ensures long-term availability and supply chain continuity.
