P0641DF-1 Equivalent & Substitute Parts

Part Overview

The P0641DF-1 is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., part of the SIDACtor® series. This component is designed for circuit protection applications, specifically in SLIC (Subscriber Line Interface Circuit) systems. The device operates at a clamping voltage of 58V and utilizes mixed technology in a surface-mount 8-SOIC package.

The P0641DF-1 carries an Obsolete product status. Identifying equivalent substitute parts is essential for ongoing system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0641DF-1 is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 58V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 1 (exact match required)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (exact match required)
• Supplier Device Package: MS-012 (exact match required)
• RoHS Status: ROHS3 Compliant (minimum compliance level)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The P0641DF-1E qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P0641DF-1E is the direct equivalent substitute for the P0641DF-1. Both components share identical electrical specifications, mechanical dimensions, and package configurations. The P0641DF-1E maintains Active product status with ROHS3 compliance and REACH Unaffected designation, ensuring long-term availability and regulatory compliance.

The primary difference is packaging format: the P0641DF-1E is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. This packaging change does not affect electrical or mechanical compatibility.

For applications requiring the P0641DF-1, the P0641DF-1E provides direct functional replacement with improved supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the P0641DF-1E be used as a direct replacement for the P0641DF-1?

A: Yes. The P0641DF-1E is electrically and mechanically identical to the P0641DF-1. Both devices feature 58V clamping voltage, mixed technology, single-circuit configuration, and 8-SOIC MS-012 packaging. The substitute is fully compatible for SLIC applications.

Q: What is the difference between the P0641DF-1 and P0641DF-1E?

A: The primary differences are product status and packaging format. The P0641DF-1 is Obsolete and supplied in bulk packaging. The P0641DF-1E is Active and supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of the P0641DF-1E affect circuit performance?

A: No. Packaging format does not affect electrical performance or mechanical compatibility. The Tape & Reel format is a supply and handling specification only, suitable for automated pick-and-place assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both the P0641DF-1 and P0641DF-1E are ROHS3 Compliant. The P0641DF-1E additionally carries REACH Unaffected status.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
