P1553ACRP Equivalent & Substitute Parts

Part Overview

The P1553ACRP is a 130V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring three-element configuration in a TO-220 modified package. The P1553ACRP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1553ACRP is determined by electrical parameter equivalence and mechanical compatibility. The following criteria establish valid substitutes:

• Voltage - Breakover: 180V
• Voltage - Off State: 130V
• Voltage - On State: 8V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Number of Elements: 3
• Capacitance: 60pF, 95pF
• Package / Case: 3-SIP
• Mounting Type: Through Hole

All identified substitutes maintain identical electrical specifications and mechanical form factor. Differences exist only in product status, packaging configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both P1553ACL and P1553ACLRP are electrically and mechanically equivalent to the obsolete P1553ACRP. Selection between these active alternatives depends on procurement and assembly requirements:

P1553ACL is supplied in bulk packaging and is suitable for applications where tape and reel packaging is not required. This part maintains ROHS3 compliance and unlimited moisture sensitivity rating.

P1553ACLRP is supplied in tape and reel configuration, optimized for automated assembly processes. This part also maintains ROHS3 compliance and unlimited moisture sensitivity rating.

Both substitute parts are active products with current manufacturing support, RoHS3 compliance, and identical electrical performance to the original P1553ACRP specification.

Frequently Asked Questions (FAQ)

Q: Can P1553ACL and P1553ACLRP be used interchangeably with P1553ACRP?

A: Yes. Both parts are electrically and mechanically identical to P1553ACRP. The differences are product status (active vs. obsolete), packaging format (bulk vs. tape and reel), and RoHS compliance level. All three parts share identical voltage ratings, current ratings, element count, capacitance values, and TO-220 modified package configuration.

Q: What is the difference between P1553ACL and P1553ACLRP?

A: The primary difference is packaging. P1553ACL is supplied in bulk packaging, while P1553ACLRP is supplied in tape and reel format. Electrical specifications and mechanical dimensions are identical. Selection depends on assembly method: bulk packaging for manual or small-batch assembly, tape and reel for automated pick-and-place operations.

Q: Why is P1553ACRP listed as obsolete?

A: P1553ACRP is classified as obsolete by the manufacturer. Active equivalents P1553ACL and P1553ACLRP are available for new designs and ongoing procurement.

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

A: P1553ACRP is RoHS non-compliant. Both P1553ACL and P1553ACLRP are ROHS3 compliant. All three parts share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: Can these parts be used in new designs?

A: P1553ACL and P1553ACLRP are active products suitable for new designs. P1553ACRP should not be used in new designs due to obsolete status.
