5KP250 Equivalent & Substitute Parts

Part Overview

The 5KP250 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for transient overvoltage protection in electronic circuits. This component features a 250V reverse standoff voltage with a 425V maximum clamping voltage and 12A peak pulse current capability. The 5KP250 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The substitute part 5KP250A provides functional equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP250 is determined by electrical and mechanical parameter equivalence within the TVS diode category. The critical parameters governing substitution are:

• Voltage - Reverse Standoff (Typ): 250V
• Voltage - Clamping (Max) @ Ipp: 425V
• Current - Peak Pulse (10/1000µs): 12A
• Power - Peak Pulse: 5000W
• Operating Temperature Range: -55°C to 175°C
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Type: Zener, Unidirectional

The 5KP250A is a direct electrical and mechanical equivalent, maintaining identical voltage ratings, current specifications, power dissipation, temperature range, and physical package configuration. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 5KP250A is the direct substitute for the 5KP250 based on complete electrical and mechanical parameter equivalence. All critical voltage ratings, current specifications, power dissipation, temperature operating range, and physical package dimensions are identical.

Product Status Consideration: The 5KP250 is classified as obsolete, while the 5KP250A maintains active product status. For new designs, production continuity, and long-term component availability, the 5KP250A is the appropriate selection.

Compliance Status: Both parts maintain RoHS compliance. The 5KP250A carries ROHS3 Compliant designation, representing the current regulatory standard. The 5KP250A also carries REACH Unaffected status, confirming compliance with chemical substance regulations.

Packaging Consideration: The 5KP250A is supplied in Tape & Reel (TR) format, standard for automated assembly processes. The original 5KP250 was supplied in bulk packaging. This distinction affects procurement and assembly methodology but does not alter electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 5KP250A be used as a direct replacement for the 5KP250 in existing circuit designs?

A: Yes. The 5KP250A is electrically and mechanically equivalent to the 5KP250. All voltage ratings, current specifications, power dissipation, operating temperature range, and physical package dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the 5KP250 and 5KP250A?

A: The primary differences are product status and packaging format. The 5KP250 is obsolete and supplied in bulk packaging. The 5KP250A is an active product supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of the 5KP250A affect compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. The component itself—the P600 axial package—remains unchanged. The physical dimensions and electrical characteristics are identical to bulk-packaged versions.

Q: Are there compliance differences between the 5KP250 and 5KP250A?

A: Both parts are RoHS compliant. The 5KP250A carries ROHS3 Compliant designation, representing the current regulatory standard. The 5KP250A also carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the 5KP250 classified as obsolete?

A: The 5KP250 has been superseded by the 5KP250A, which maintains identical electrical and mechanical specifications while carrying active product status. Littelfuse has consolidated the product line to the 5KP250A for ongoing production and support.

Q: What is the Moisture Sensitivity Level (MSL) for the 5KP250A?

A: The 5KP250A carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The component can be stored and handled without special humidity control measures.

Q: Are the operating temperature ranges identical?

A: Yes. Both the 5KP250 and 5KP250A operate across the identical temperature range of -55°C to 175°C (TJ), ensuring thermal performance equivalence across all environmental conditions.
