Substitute Part Grouping Explanation

Substitution of the P1602AB60 is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Off-State: 65V/130V; Breakover: 95V/190V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 250A; Peak Pulse 10/1000µs: 80A; Hold Current: 150mA)
• Dual-element configuration (Number of Elements: 2)
• Capacitance values (85pF, 145pF)
• Physical package format (TO-220 Modified 3-SIP)
• Through-hole mounting compatibility

The P1602ABL60 meets all electrical and mechanical requirements for direct substitution with the P1602AB60, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P1602ABL60 is the direct electrical and mechanical equivalent of the P1602AB60. Selection between these parts should be based on the following criteria:

P1602ABL60 is preferred for new designs and production due to its Active product status and ROHS3 compliance. This part maintains identical electrical performance while meeting current regulatory requirements and ensuring long-term supply chain availability.

P1602AB60 remains suitable for legacy system maintenance where existing inventory is available and RoHS compliance is not a design constraint. However, sourcing this obsolete part may present supply challenges.

Both parts are functionally interchangeable in circuit applications requiring dual-element TVS thyristor protection with the specified voltage and current ratings in TO-220 Modified packaging.

Frequently Asked Questions (FAQ)

Q: Can P1602ABL60 be used as a direct replacement for P1602AB60?

A: Yes. The P1602ABL60 is electrically and mechanically equivalent to the P1602AB60. All critical parameters—voltage ratings, current specifications, element count, capacitance, and package format—are identical. The primary differences are product status (Active vs. Obsolete) and RoHS compliance level.

Q: What is the difference between the P1602AB60 and P1602ABL60 packaging?

A: Both parts use identical TO-220 Modified 3-SIP package format and through-hole mounting. The distinction is in supplier packaging: P1602AB60 uses standard packaging, while P1602ABL60 is supplied in bulk format. This does not affect electrical performance or circuit compatibility.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical electrical specifications: 65V/130V off-state voltage, 95V/190V breakover voltage, 4V on-state voltage, 250A peak pulse current (8/20µs), 80A peak pulse current (10/1000µs), 150mA hold current, and 85pF/145pF capacitance values.

Q: Which part should be selected for new product designs?

A: The P1602ABL60 is recommended for new designs. It maintains Active product status, ensuring ongoing manufacturer support and supply availability. Additionally, ROHS3 compliance aligns with current environmental and regulatory standards.

Q: Is the P1602AB60 still available for purchase?

A: The P1602AB60 is classified as obsolete. While limited inventory may be available through component distributors, the P1602ABL60 is the recommended alternative for ensuring reliable supply and regulatory compliance.

Q: Can these parts be used interchangeably in existing circuit boards?

A: Yes. The identical TO-220 Modified 3-SIP package and through-hole mounting configuration ensure direct pin-for-pin compatibility. No circuit modifications or PCB redesign is required when substituting between these parts.
