Substitute Part Grouping Explanation

The PTVS10-076C-TH (Bourns Inc.) qualifies as a direct substitute for the AK10-076C based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Voltage - Reverse Standoff: 76V
• Voltage - Breakdown (Min): 85V
• Voltage - Clamping (Max) @ Ipp: 140V
• Current - Peak Pulse (10/1000µs): 10000A (10kA) (8/20µs)
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Package / Case: Axial, Right Angle Bend (24.15mm Center)
• RoHS Status: ROHS3 Compliant
• HTSUS Code: 8541.10.0080

The substitute part maintains electrical equivalence across all critical voltage and current ratings, ensuring functional interchangeability in circuit applications. Both components are classified as general-purpose TVS diodes with identical mechanical form factors and through-hole mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AK10-076C and PTVS10-076C-TH are active production components with ROHS3 compliance certification. The AK10-076C offers a wider operating temperature range (-55°C to 150°C) compared to the PTVS10-076C-TH (-55°C to 125°C), making it suitable for applications requiring extended high-temperature performance. The PTVS10-076C-TH presents a lower capacitance value (5600pF versus 6500pF at 10kHz), which may be advantageous in high-frequency signal integrity applications where minimized parasitic capacitance is required.

Selection between these components should be based on specific application temperature requirements and capacitance constraints. Both parts maintain identical electrical protection characteristics and mechanical compatibility for direct circuit board substitution.

Frequently Asked Questions (FAQ)

Q: Can PTVS10-076C-TH be used as a direct replacement for AK10-076C in existing designs?

A: Yes. Both components share identical voltage ratings (76V standoff, 85V breakdown, 140V clamping), current ratings (10kA peak pulse), and mechanical form factors (axial through-hole, 24.15mm center). Direct PCB substitution is mechanically and electrically compatible.

Q: What is the difference in operating temperature ranges between these parts?

A: The AK10-076C operates from -55°C to 150°C, while the PTVS10-076C-TH operates from -55°C to 125°C. Applications requiring sustained operation above 125°C should use the AK10-076C.

Q: How do the capacitance values differ, and does this affect circuit performance?

A: The AK10-076C has 6500pF capacitance at 10kHz, while the PTVS10-076C-TH has 5600pF. In high-frequency circuits where parasitic capacitance affects signal integrity, the lower capacitance of the PTVS10-076C-TH may provide improved performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the AK10-076C and PTVS10-076C-TH are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the REACH compliance status of these parts?

A: The AK10-076C is REACH Unaffected. The PTVS10-076C-TH is REACH Affected. Applications subject to REACH regulations should verify compliance requirements with the respective manufacturer.
