P2202AC Equivalent & Substitute Parts

Part Overview

The P2202AC is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications. This component features dual-element configuration with 90V/180V off-state voltage ratings and 400A peak pulse current capability in a 3-SIP TO-220 Modified package. The P2202AC is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2202AC is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

Electrical Parameters (Must Match):

• Voltage - Breakover: 130V, 260V
• Voltage - Off State: 90V, 180V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 400 A
• Current - Peak Pulse (10/1000µs): 100 A
• Current - Hold (Ih): 150 mA
• Number of Elements: 2
• Capacitance: 65pF, 115pF

Mechanical Parameters (Must Match):

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

The P2202ACL and P2202ACLRP are direct electrical and mechanical equivalents of the P2202AC. Both parts maintain identical electrical specifications and physical form factor. The primary differences are packaging configuration (Bulk versus Tape & Reel) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

P2202ACL (Bulk Packaging): This part is the direct active equivalent of the P2202AC with identical electrical and mechanical specifications. P2202ACL carries ROHS3 compliance status, addressing regulatory requirements for new designs. Bulk packaging is suitable for applications requiring standard component quantities without automated assembly constraints.

P2202ACLRP (Tape & Reel Packaging): This part provides the same electrical and mechanical performance as P2202AC with Tape & Reel packaging configuration. ROHS3 compliance is maintained. Tape & Reel packaging is specified for high-volume production environments utilizing automated pick-and-place assembly equipment.

Both P2202ACL and P2202ACLRP are suitable direct replacements for the obsolete P2202AC in new designs and production continuity scenarios. Selection between these two variants depends solely on packaging requirements and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can P2202ACL or P2202ACLRP be used as direct replacements for P2202AC?

A: Yes. Both parts are electrically and mechanically equivalent to P2202AC. All voltage ratings, current specifications, capacitance values, and physical form factors are identical. The primary differences are product status (Active versus Obsolete) and packaging configuration.

Q: What is the difference between P2202ACL and P2202ACLRP?

A: Both parts have identical electrical specifications and physical dimensions. The difference is packaging: P2202ACL is supplied in Bulk packaging, while P2202ACLRP is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated assembly lines, while Bulk packaging is suitable for manual assembly or standard component handling.

Q: Are there RoHS compliance differences between the substitute parts?

A: Yes. The original P2202AC is RoHS non-compliant. Both substitute parts, P2202ACL and P2202ACLRP, are ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: Will the 3-SIP TO-220 Modified package fit existing PCB layouts designed for P2202AC?

A: Yes. P2202ACL and P2202ACLRP maintain the identical 3-SIP TO-220 Modified package configuration as P2202AC. No PCB layout modifications are required for mechanical compatibility.

Q: What inventory status should be considered when selecting between substitute parts?

A: P2202ACL (Bulk) has 2,300 units in stock, while P2202ACLRP (Tape & Reel) has 711 units in stock. Inventory availability may influence selection based on production volume and delivery timeline requirements.
