P1602ABRP Equivalent & Substitute Parts

Part Overview

The P1602ABRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 65V/130V off-state voltage ratings with 250A peak pulse current capability. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1602ABRP are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution validity:

Electrical Parameters (Must Match Exactly):

• Voltage - Off State: 65V, 130V
• Voltage - Breakover: 95V, 190V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 250 A
• Current - Peak Pulse (10/1000µs): 80 A
• Current - Hold (Ih): 150 mA
• Number of Elements: 2
• Capacitance: 85pF, 145pF

Mechanical Parameters (Must Match Exactly):

• Package / Case: 3-SIP
• Mounting Type: Through Hole
• Supplier Device Package: TO-220 Modified

Both substitute parts (P1602ABL and P1602ABLRP) satisfy these criteria. The distinction between substitutes is packaging format: P1602ABL is supplied in bulk packaging, while P1602ABLRP is supplied in tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

Both P1602ABL and P1602ABLRP are direct functional equivalents to the obsolete P1602ABRP, with identical electrical and mechanical specifications. Selection between the two substitute parts depends on procurement and assembly requirements:

P1602ABL (Bulk Packaging): Suitable for applications requiring standard bulk component delivery. This part maintains active product status with ROHS3 compliance certification.

P1602ABLRP (Tape & Reel Packaging): Recommended for automated assembly processes requiring tape and reel format. This part also maintains active product status with ROHS3 compliance certification.

Both substitute parts offer improved compliance posture compared to the main part, with ROHS3 certification and REACH unaffected status. The transition from the obsolete P1602ABRP to either active substitute part ensures long-term design support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can P1602ABL and P1602ABLRP be used interchangeably with P1602ABRP?

A: Yes. Both parts are direct substitutes with identical electrical parameters (voltage ratings, current ratings, capacitance) and mechanical specifications (3-SIP package, TO-220 Modified supplier package, through-hole mounting). The only difference is packaging format: bulk versus tape and reel.

Q: What is the primary reason to transition from P1602ABRP to a substitute part?

A: The P1602ABRP is classified as obsolete. P1602ABL and P1602ABLRP are active products, ensuring continued availability, manufacturing support, and compliance with current regulatory standards including ROHS3.

Q: Are there any electrical performance differences between the three parts?

A: No. All three 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 substitute should I select for my application?

A: Selection depends on your assembly process. Use P1602ABL for manual or semi-automated assembly with bulk component handling. Use P1602ABLRP for fully automated assembly lines requiring tape and reel format components.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both P1602ABL and P1602ABLRP are ROHS3 compliant, whereas the original P1602ABRP is RoHS non-compliant. This represents an improvement in regulatory compliance.

Q: Can I mix packaging formats in the same design?

A: Yes. Since both substitute parts are electrically and mechanically identical, they can be used in the same circuit design. Packaging format selection is determined by procurement and assembly methodology, not circuit requirements.
