Engineering Selection Recommendations
The P6002ACL is the appropriate substitute for the CR6002AC based on the following factors:
- Product Status: The CR6002AC is obsolete, while the P6002ACL maintains active production status, ensuring long-term availability and supply chain continuity.
- Regulatory Compliance: The P6002ACL achieves ROHS3 compliance, whereas the CR6002AC is RoHS non-compliant. Selection of the P6002ACL aligns with current environmental and regulatory requirements.
- Electrical Equivalence: Both components share identical voltage ratings (275V standoff/off-state) and bidirectional channel configuration, confirming functional interchangeability within the protected circuit.
- Package Compatibility: The 3-SIP TO-220 Modified package is identical across both parts, permitting direct substitution without PCB modification.
- REACH Status: The P6002ACL is REACH Unaffected, providing additional regulatory assurance for international applications.
Frequently Asked Questions (FAQ)
Q: Can the P6002ACL be used as a direct replacement for the CR6002AC without PCB modifications?
A: Yes. Both components utilize the identical 3-SIP TO-220 Modified package configuration, enabling direct pin-for-pin substitution without PCB redesign or layout changes.
Q: What is the primary difference between the CR6002AC and P6002ACL?
A: The CR6002AC is a Zener-type TVS diode, while the P6002ACL is a TVS Thyristor (SIDACtor®) technology. Both maintain equivalent 275V voltage ratings and bidirectional protection, but the P6002ACL offers active product status and ROHS3 compliance.
Q: Are the voltage ratings identical between these two parts?
A: The critical voltage specification—reverse standoff / off-state voltage—is identical at 275V for both components. The P6002ACL offers additional voltage options (550V off-state), but the 275V rating ensures direct functional equivalence.
Q: Does the P6002ACL support the same operating temperature range?
A: Yes. Both the CR6002AC and P6002ACL operate across -55°C to 175°C (TJ), maintaining thermal performance equivalence across all environmental conditions.
Q: What is the significance of the P6002ACL's ROHS3 compliance?
A: ROHS3 compliance indicates the P6002ACL meets current environmental regulations restricting hazardous substances. This is particularly important for new designs and applications subject to regulatory requirements, whereas the CR6002AC's RoHS non-compliant status limits its use in regulated environments.
Q: Are moisture sensitivity levels equivalent?
A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
