5KP7.0A-B Equivalent & Substitute Parts

Part Overview

The 5KP7.0A-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This through-hole component operates with a 7V reverse standoff voltage and provides 5000W peak pulse power dissipation. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity level rating. Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP7.0A-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 425A
• Power - Peak Pulse: 5000W (5kW)
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C to 175°C (TJ)

The substitute part 5KP7.0A differs only in packaging format (Cut Tape versus Bulk), while maintaining identical electrical performance and mechanical specifications. This substitution is valid for applications where packaging configuration does not impose assembly or procurement constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP7.0A-B and 5KP7.0A are active production components from Littelfuse Inc. with ROHS3 compliance certification. Selection between these parts is determined by packaging and procurement requirements rather than electrical performance. The 5KP7.0A-B in Bulk packaging is suitable for high-volume manufacturing environments with integrated component handling systems. The 5KP7.0A in Cut Tape (CT) packaging accommodates automated pick-and-place assembly processes and smaller production runs. Both parts satisfy identical electrical and thermal specifications for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can 5KP7.0A be used as a direct replacement for 5KP7.0A-B?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: 5KP7.0A-B is supplied in Bulk, while 5KP7.0A is supplied in Cut Tape (CT). Selection depends on assembly process compatibility and procurement volume requirements.

Q: What is the significance of the packaging difference between Bulk and Cut Tape?

A: Bulk packaging is used for manual handling and high-volume reel-based assembly. Cut Tape (CT) packaging is designed for automated pick-and-place equipment and provides individual component separation. Both formats contain the identical P600 axial through-hole component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance and active product status. Moisture sensitivity level (MSL) is rated as 1 (Unlimited) for both variants.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: 7V reverse standoff voltage, 7.78V minimum breakdown voltage, 12V maximum clamping voltage, 425A peak pulse current, and 5000W peak pulse power rating. All other specifications, including operating temperature range and package type, must also remain identical.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process is compatible with the packaging format. Both parts use identical P600 axial through-hole mounting and can be soldered into the same PCB footprint. Verify that your assembly equipment supports the specific packaging format (Bulk or Cut Tape) you select.
