P1500EB Equivalent & Substitute Parts

Part Overview

The P1500EB is a 140V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a TO-226-2 package. This component is designed for transient voltage suppression applications requiring 250A peak pulse current capability. The P1500EB is currently classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500EB is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Voltage - Off State: 140V (exact match required)
• Voltage - Breakover: 180V (exact match required)
• Voltage - On State: 4V (exact match required)
• Current - Peak Pulse (8/20µs): 250A (exact match required)
• Current - Peak Pulse (10/1000µs): 80A (exact match required)
• Current - Hold (Ih): 150mA (exact match required)
• Capacitance: 55pF (exact match required)
• Package / Case: TO-226-2, TO-92-2 (exact match required)
• Mounting Type: Through Hole (exact match required)

The P1500EBL meets all electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The P1500EBL is the direct substitute for the obsolete P1500EB. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications.

Key differentiation factors:

• Product Status: P1500EB is obsolete; P1500EBL is active and currently in production
• RoHS Compliance: P1500EB is RoHS non-compliant; P1500EBL is ROHS3 compliant
• REACH Status: P1500EBL is REACH unaffected
• Inventory Availability: P1500EBL has significantly higher stock levels (20,200 pcs vs. 708 pcs)
• Packaging: P1500EB is tape and reel; P1500EBL is bulk

For new designs and ongoing system support, P1500EBL is the appropriate selection due to active product status, regulatory compliance, and availability.

Frequently Asked Questions (FAQ)

Q: Can P1500EBL replace P1500EB in existing applications?

A: Yes. The P1500EBL is electrically and mechanically identical to the P1500EB. All voltage ratings, current specifications, and package dimensions are equivalent. The primary difference is product status and regulatory compliance.

Q: What is the difference between P1500EB and P1500EBL?

A: The P1500EB is obsolete and RoHS non-compliant. The P1500EBL is an active product that meets ROHS3 compliance standards. Electrical and mechanical parameters are identical.

Q: Are there any package or mounting differences?

A: Both parts use TO-226-2 and TO-92-2 packages with through-hole mounting. No PCB layout modifications are required for substitution.

Q: Why is P1500EB obsolete?

A: The P1500EB has been superseded by the P1500EBL, which offers improved regulatory compliance and better availability.

Q: What certifications does P1500EBL hold?

A: P1500EBL is ROHS3 compliant and REACH unaffected.
