15KP70CA-TP Equivalent & Substitute Parts

Part Overview

The 15KP70CA-TP is a bidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This axial through-hole component operates across a wide temperature range (-55°C to 175°C) and is ROHS3 compliant. The part is currently active in production with 643 units in stock. Substitute parts are necessary when the original component becomes unavailable, when alternative packaging formats are required, or when different power dissipation levels are needed for specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 15KP70CA-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 70V to maintain circuit protection specifications
• Bidirectional Channels: Must be 1 channel for equivalent functionality
• Mounting Type: Must be Through Hole for PCB compatibility
• Type: Must be Zener diode for equivalent electrical behavior
• Operating Temperature Range: Must support -55°C to 175°C minimum
• Power - Peak Pulse: Determines transient energy handling capability; substitutes may vary based on application requirements
• Voltage - Clamping (Max) @ Ipp: Must remain within acceptable range (109V–114V) for circuit protection
• RoHS Compliance: Must maintain ROHS3 compliance for regulatory requirements

The substitute parts listed below meet these core substitution criteria while offering variations in packaging format, power rating, and manufacturer.

Parameter Comparison

Engineering Selection Recommendations

15KPA70CA (MDE Semiconductor Inc)

This substitute maintains identical power rating (15kW) and operating temperature range as the main part. Both components are ROHS3 compliant and active in production. The primary difference is packaging format (P600 vs. R-6 axial) and manufacturer. This substitute is suitable for direct replacement when P600 package compatibility exists on the PCB.

30KPA70CA (MDE Semiconductor Inc)

This substitute doubles the power dissipation capability to 30kW while maintaining the 70V reverse standoff voltage and full operating temperature range. ROHS3 compliance is maintained. Selection of this part is appropriate when higher transient energy absorption is required or when circuit design margins demand increased power handling. The P600 package format must be compatible with the PCB layout.

5KP70CA (Diotec Semiconductor)

This substitute reduces power rating to 5kW, one-third of the main part specification. The operating temperature minimum is -50°C (versus -55°C for the main part). RoHS compliance status is not applicable for this component. This substitute is suitable only for applications with reduced transient energy requirements and when the -50°C minimum temperature is acceptable for the end application.

Frequently Asked Questions (FAQ)

Q: Can I use the 15KPA70CA as a direct replacement for the 15KP70CA-TP?

A: The 15KPA70CA is electrically equivalent with identical voltage and power specifications. However, the package format differs (P600 vs. R-6 axial). Physical PCB layout compatibility must be confirmed before substitution. Both parts are ROHS3 compliant and active in production.

Q: What is the difference between the 15KPA70CA and 30KPA70CA?

A: Both parts share the same 70V reverse standoff voltage and operating temperature range. The 30KPA70CA provides double the peak pulse power (30kW vs. 15kW), resulting in higher peak pulse current (278A vs. 132.9A). Selection depends on the transient energy levels present in the application circuit.

Q: Is the 5KP70CA suitable for all applications using the 15KP70CA-TP?

A: No. The 5KP70CA has one-third the power rating (5kW vs. 15kW) and a higher minimum operating temperature (-50°C vs. -55°C). This substitute is only appropriate for applications with lower transient energy requirements and when the reduced temperature range is acceptable.

Q: Do all substitute parts maintain ROHS3 compliance?

A: The 15KPA70CA and 30KPA70CA are ROHS3 compliant. The 5KP70CA has not applicable RoHS status. Regulatory requirements for your application must be confirmed before selecting this substitute.

Q: What is the significance of the different package formats (R-6 vs. P600)?

A: R-6 and P600 are different axial through-hole package geometries. Physical dimensions and lead spacing differ between formats. PCB footprint compatibility must be verified before substitution. Consult component datasheets for precise dimensional specifications.

Q: Can I use a higher power-rated substitute (30KPA70CA) in place of the 15KP70CA-TP?

A: Yes, from an electrical protection standpoint. The 30KPA70CA maintains the same voltage specifications and temperature range while providing additional transient energy handling capability. PCB layout compatibility with the P600 package must be confirmed.
