SP1010-04UTG Equivalent & Substitute Parts

Part Overview

The SP1010-04UTG is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 6V reverse standoff voltage rating and is housed in a compact 6-µDFN (1.25x1.0) package. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP1010-04UTG is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 6V (Max)
• Voltage - Breakdown (Min): 7V
• Type: Zener
• Unidirectional Channels: 4
• Applications: General Purpose

Mechanical Compatibility Criteria:

• Package / Case: 6-XDFN
• Supplier Device Package: 6-µDFN (1.25x1.0)
• Mounting Type: Surface Mount

Environmental & Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SP1011-04UTG qualifies as a direct substitute, maintaining identical reverse standoff voltage, breakdown voltage, package configuration, and environmental specifications while providing enhanced clamping performance and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The SP1011-04UTG is the primary substitute for the SP1010-04UTG. Both components maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with current manufacturing and environmental standards. The SP1011-04UTG provides identical electrical performance at the reverse standoff and breakdown voltage levels while offering documented clamping voltage and peak pulse current specifications. The extended operating temperature range (-40°C ~ 125°C junction temperature versus -40°C ~ 85°C ambient temperature) provides additional thermal margin for demanding applications.

Both parts are classified as obsolete; however, inventory availability is confirmed for both components. Selection between these parts should be based on application-specific requirements for clamping voltage performance and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the SP1011-04UTG directly replace the SP1010-04UTG in existing designs?

A: Yes. Both components share identical reverse standoff voltage (6V Max), breakdown voltage (7V Min), package configuration (6-µDFN 1.25x1.0), and mounting type (Surface Mount). The SP1011-04UTG provides additional performance data and extended temperature rating.

Q: What is the primary difference between these two parts?

A: The SP1011-04UTG specifies clamping voltage (10.2V maximum) and peak pulse current (2A at 8/20µs), whereas the SP1010-04UTG does not provide these parameters. The SP1011-04UTG also supports a higher junction temperature range (up to 125°C versus 85°C ambient).

Q: Are both parts RoHS compliant?

A: Yes. Both SP1010-04UTG and SP1011-04UTG are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What package considerations apply to substitution?

A: Both parts use the identical 6-µDFN (1.25x1.0) surface-mount package. No PCB layout or footprint modifications are required for substitution.

Q: Why is the SP1010-04UTG classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The SP1011-04UTG remains available as a functional equivalent with documented electrical specifications suitable for design continuity.
