Substitute Part Grouping Explanation

Substitution of the P0901SA is determined by strict alignment of the following critical parameters:

• Voltage - Clamping: 98V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 1 (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Applications: SLIC (exact match required)

The P0901SALRP meets all substitution criteria as a direct equivalent. This part maintains identical electrical specifications and mechanical compatibility while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The P0901SALRP is the direct substitute for the obsolete P0901SA. Both parts are manufactured by Littelfuse and share identical electrical and mechanical specifications for SLIC circuit protection applications.

Key distinctions between the parts:

Product Status: The P0901SA is obsolete, while the P0901SALRP maintains active production status. This ensures long-term availability and supply chain continuity for new designs and ongoing support requirements.

Compliance: The P0901SALRP achieves ROHS3 compliance, whereas the P0901SA is RoHS non-compliant. For applications subject to RoHS regulations, the P0901SALRP is the appropriate selection.

Packaging Format: The P0901SA is supplied in bulk packaging, while the P0901SALRP is available in Tape & Reel format, which is standard for automated assembly processes.

Both parts maintain identical moisture sensitivity levels and export classifications, ensuring no additional handling or regulatory considerations are introduced through substitution.

Frequently Asked Questions (FAQ)

Q: Can the P0901SALRP be used as a direct replacement for the P0901SA?

A: Yes. The P0901SALRP is a direct substitute. Both parts share identical voltage clamping (98V), technology type (Mixed Technology), circuit count (1), package format (DO-214AA, SMB), and SLIC application specifications.

Q: What is the primary reason to transition from P0901SA to P0901SALRP?

A: The P0901SA is obsolete. The P0901SALRP is an active product from the same manufacturer with identical electrical and mechanical characteristics, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Yes. The P0901SALRP is ROHS3 compliant, while the P0901SA is RoHS non-compliant. For applications requiring RoHS compliance, the P0901SALRP is the required selection.

Q: Does the packaging format affect electrical performance?

A: No. The packaging format difference (bulk versus Tape & Reel) does not affect electrical performance or functional characteristics. The Tape & Reel format of the P0901SALRP is optimized for automated assembly processes.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both the P0901SA and P0901SALRP have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for either part.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The P0901SALRP is a direct electrical and mechanical equivalent to the P0901SA. No circuit modifications or design changes are required for substitution.
