Compliance Alignment: Both parts maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory consistency.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, confirming equivalent environmental handling requirements.

Active Product Status: The RCLAMP0504N.TCT is Active, providing long-term availability and supply chain continuity compared to the Obsolete SP4001-04UTG.

Parameter Comparison

Engineering Selection Recommendations

The RCLAMP0504N.TCT serves as the primary substitute for the obsolete SP4001-04UTG based on functional equivalence within the 5V TVS protection class. The transition from Littelfuse to Semtech maintains regulatory compliance through identical ROHS3 and EAR99 classifications. The Active product status of the RCLAMP0504N.TCT ensures sustained component availability with 19,434 units currently in stock, compared to the limited remaining inventory of the obsolete SP4001-04UTG.

Both components share MSL 1 (Unlimited) moisture sensitivity ratings, eliminating additional handling or storage requirement changes during substitution. The RCLAMP0504N.TCT operates within the specified 5V protection parameters, with documented clamping voltage of 17.5V and peak pulse current of 12A (8/20µs), providing measurable performance data for circuit validation.

Frequently Asked Questions (FAQ)

Q: Can the RCLAMP0504N.TCT directly replace the SP4001-04UTG in existing designs?

A: Yes, within the 5V TVS protection class. Both components maintain identical voltage standoff and breakdown characteristics at 5V, with equivalent regulatory compliance (ROHS3, EAR99) and moisture sensitivity ratings (MSL 1).

Q: What are the key differences between these two parts?

A: The primary difference is product status: SP4001-04UTG is Obsolete while RCLAMP0504N.TCT is Active. The RCLAMP0504N.TCT provides documented electrical specifications including 17.5V clamping voltage and 12A peak pulse current, whereas the SP4001-04UTG specifications are limited. Both maintain 5V protection class equivalence.

Q: Are there packaging considerations for this substitution?

A: The SP4001-04UTG packaging details are not specified in available documentation. The RCLAMP0504N.TCT uses 6-UDFN Exposed Pad (SLP2020P6) surface mount packaging with Cut Tape (CT) and Digi-Reel® options. Physical footprint verification against original design requirements is necessary.

Q: Does the RCLAMP0504N.TCT maintain the same environmental compliance?

A: Yes. Both components are ROHS3 compliant with MSL 1 (Unlimited) ratings. The RCLAMP0504N.TCT additionally carries REACH Unaffected status, providing expanded regulatory coverage.

Q: What is the inventory status for the substitute part?

A: The RCLAMP0504N.TCT has 19,434 units in stock as new original inventory, ensuring immediate availability for production and design transitions.
