P0641UARP Equivalent & Substitute Parts

Part Overview

The P0641UARP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for circuit protection in SLIC applications. This mixed-technology TVS operates at a clamping voltage of 77V and features four circuits in a 6-SMD, Gull Wing surface mount package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P0641UARP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 77V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 4 (exact match required)
• Package / Case: 6-SMD, Gull Wing (exact match required)
• Supplier Device Package: MS-013 (exact match required)
• Applications: SLIC (functional equivalence required)

The P0641UALRP meets all substitution criteria as a direct equivalent. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), with no variation in electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The P0641UALRP is the direct functional equivalent for the obsolete P0641UARP. Both parts share identical electrical and mechanical specifications, including clamping voltage, circuit count, package configuration, and SLIC application suitability.

The P0641UALRP offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the P0641UALRP meets ROHS3 compliance requirements, whereas the P0641UARP is non-compliant. For new designs or system refreshes, the P0641UALRP is the appropriate selection. For legacy system maintenance requiring exact form-fit-function replacement, the P0641UALRP provides electrical and mechanical compatibility without modification.

Frequently Asked Questions (FAQ)

Q: Can the P0641UALRP directly replace the P0641UARP on existing PCBs?

A: Yes. Both parts are identical in electrical performance, clamping voltage (77V), circuit configuration (4 circuits), and physical package (6-SMD, Gull Wing, MS-013). No PCB modifications are required.

Q: What is the difference between P0641UARP and P0641UALRP?

A: The primary differences are packaging format (bulk versus Tape & Reel) and product lifecycle status. The P0641UARP is obsolete; the P0641UALRP is active. The P0641UALRP also meets ROHS3 compliance, while the P0641UARP does not. Electrical and mechanical specifications are identical.

Q: Why is the P0641UARP listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued active production and support. The P0641UALRP, as an active equivalent, is the recommended source for ongoing procurement.

Q: Are there any compliance differences between these parts?

A: Yes. The P0641UALRP is ROHS3 compliant and REACH unaffected. The P0641UARP is RoHS non-compliant. Both share identical Moisture Sensitivity Level (MSL 1, Unlimited) and ECCN/HTSUS classifications.

Q: What applications are these parts suitable for?

A: Both parts are designed for SLIC (Subscriber Line Interface Circuit) applications requiring transient voltage suppression at 77V clamping voltage with four independent circuits.
