5KP58CA Equivalent & Substitute Parts
Part Overview
The 5KP58CA is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose voltage clamping applications. This through-hole component operates across a temperature range of -55°C to 175°C and is RoHS3 compliant. The part is currently active in production with 5582 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this TVS diode category.

Substitute Part Grouping Explanation
Substitution of the 5KP58CA is determined by maintaining the following critical electrical parameters: reverse standoff voltage (58V nominal), breakdown voltage range (64.4V minimum), and bidirectional channel configuration (1 channel). Mechanical compatibility requires through-hole mounting with axial package orientation. All substitute parts must maintain RoHS3 compliance and operate within the specified temperature range.
Two substitute parts meet these criteria:
15KP58CA-TP maintains identical reverse standoff voltage (58V) and breakdown voltage (64.4V minimum). The clamping voltage is 94V, which is within acceptable tolerance of the main part's 93.6V specification. This part is manufactured by Micro Commercial Co and supplied in R-6 axial package format.
AK3-058C-BP maintains the same reverse standoff voltage (58V) and comparable breakdown voltage (64V minimum). The clamping voltage is 110V, representing a higher clamping characteristic. This part features a right-angle bend package configuration (24.15mm center) and operates within a temperature range of -55°C to 150°C.

Engineering Selection Recommendations
All three parts maintain RoHS3 compliance and active production status. Selection between the main part and substitutes depends on specific application requirements:
The 5KP58CA and 15KP58CA-TP share identical voltage specifications (58V reverse standoff, 64.4V breakdown minimum) with clamping voltages within 0.4V of each other. Both operate across the full -55°C to 175°C temperature range. The primary difference is package geometry: P600 versus R-6 axial format.
The AK3-058C-BP provides higher clamping voltage (110V) and operates within a reduced temperature range (-55°C to 150°C maximum junction temperature). This part is suitable for applications where higher clamping voltage is acceptable and the upper temperature limit does not exceed 150°C.
Frequently Asked Questions (FAQ)
Q: Can 15KP58CA-TP be used as a direct replacement for 5KP58CA?
A: Yes, provided the R-6 axial package geometry is compatible with the PCB layout. Both parts maintain identical reverse standoff voltage (58V), breakdown voltage (64.4V minimum), and operating temperature range (-55°C to 175°C). Clamping voltage differs by 0.4V (94V versus 93.6V), which is within typical tolerance for TVS diode applications.
Q: What are the package differences between these parts?
A: The 5KP58CA uses P600 axial package format. The 15KP58CA-TP uses R-6 axial format. The AK3-058C-BP features a right-angle bend configuration with 24.15mm center spacing, requiring different PCB footprint design.
Q: Is AK3-058C-BP suitable for high-temperature applications?
A: The AK3-058C-BP operates to a maximum junction temperature of 150°C, compared to 175°C for the 5KP58CA and 15KP58CA-TP. Applications requiring operation above 150°C require the main part or 15KP58CA-TP.
Q: What determines substitution eligibility for TVS diodes?
A: Substitution is determined by matching reverse standoff voltage, breakdown voltage range, bidirectional channel configuration, through-hole mounting type, and compliance certifications. Clamping voltage and package geometry must be compatible with circuit design requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. The 5KP58CA, 15KP58CA-TP, and AK3-058C-BP are all RoHS3 compliant and REACH unaffected.
