Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP58A-E3/54 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Unidirectional Channels: 1
• Voltage - Reverse Standoff (Typ): 58V
• Voltage - Breakdown (Min): 64.4V minimum
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Within acceptable circuit design margins
• Current - Peak Pulse (10/1000µs): Equal to or greater than 53.4A
• Power - Peak Pulse: Equal to or greater than 5000W

Substitute parts must maintain identical mechanical compatibility (P600 axial through-hole package) and electrical specifications within the defined voltage and current parameters to ensure direct interchangeability in the circuit.

Parameter Comparison

Engineering Selection Recommendations

5KP58A (Littelfuse): This substitute maintains electrical parity with the original 5KP58A-E3/54 across all critical parameters. The part is ROHS3 compliant, active in product status, and available in equivalent packaging. The clamping voltage (93.6V) and peak pulse current (54.5A) are within acceptable operational margins of the original specification. This substitute is suitable for direct replacement in applications requiring 5kW peak pulse power dissipation.

15KPA58A (MDE Semiconductor Inc): This part qualifies as a substitute with enhanced performance characteristics. It maintains the same 58V reverse standoff voltage and P600 axial through-hole package configuration. The 15KPA58A provides increased peak pulse current (161A) and power dissipation (15kW), making it suitable for applications requiring higher transient energy absorption. The breakdown voltage (64.8V minimum) remains within acceptable tolerance. This part is ROHS3 compliant and active in product status. Selection of this substitute should be based on circuit requirements for enhanced surge protection capability.

Frequently Asked Questions (FAQ)

Q: Can the 5KP58A (Littelfuse) be used as a direct replacement for the 5KP58A-E3/54?

A: Yes. Both parts share identical reverse standoff voltage (58V), breakdown voltage (64.4V), operating temperature range (-55°C to 175°C), and P600 axial through-hole package configuration. The clamping voltage and peak pulse current specifications are within acceptable operational margins, confirming direct interchangeability.

Q: What is the primary difference between the 5KP58A and 15KPA58A substitutes?

A: The 15KPA58A provides enhanced transient protection with 161A peak pulse current and 15kW power dissipation compared to the 5KP58A specifications of 53.4A and 5kW respectively. Both maintain the same 58V voltage rating and P600 package. Selection depends on the circuit's transient energy requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 5KP58A (Littelfuse) and 15KPA58A (MDE Semiconductor Inc) are both ROHS3 compliant, matching the compliance status of the original 5KP58A-E3/54.

Q: Can the 15KPA58A be used in applications designed for the 5KP58A-E3/54?

A: Yes. The 15KPA58A maintains the same voltage specifications (58V reverse standoff, 64.8V minimum breakdown) and package configuration (P600 axial through-hole). The higher current and power ratings provide enhanced protection without compromising circuit compatibility.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are available in P600 axial through-hole packaging, ensuring mechanical compatibility with the original 5KP58A-E3/54 design. The 5KP58A (Littelfuse) is supplied in Cut Tape (CT) packaging, while the 15KPA58A (MDE Semiconductor Inc) is supplied in Bulk packaging.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. All parts, including the original 5KP58A-E3/54 and both substitutes, have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
