Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PSR-28690-2 are identified based on the following criteria:

Manufacturer Consistency: All substitute parts are sourced from Littelfuse Inc., ensuring design continuity and manufacturing standards alignment.

Product Category: Substitute parts are polymeric PTC resettable fuses, maintaining the same functional classification and operational principle as the original component.

Compliance Requirements: Substitute parts maintain RoHS compliance status and share the same ECCN (EAR99) and HTSUS (8533.40.8070) classifications, ensuring regulatory and trade compliance equivalence.

Active Product Status: Substitute parts are classified as active products in current production, providing long-term availability and supply chain reliability.

The 1206L600SLWR is identified as a direct substitute based on these standardized parameters and represents the current-generation equivalent within Littelfuse's PTC resettable fuse portfolio.

Parameter Comparison

Engineering Selection Recommendations

The 1206L600SLWR is the identified substitute for the obsolete PSR-28690-2 based on manufacturer alignment, product category equivalence, and regulatory compliance matching.

Compliance Verification: Both components maintain RoHS compliance status. The 1206L600SLWR carries ROHS3 compliance, representing the current regulatory standard. Both components share identical ECCN and HTSUS classifications, ensuring trade and export compliance continuity.

Product Status Advantage: The 1206L600SLWR is an active product in current production, providing assured long-term availability and supply chain stability compared to the obsolete PSR-28690-2.

Certification Alignment: The 1206L600SLWR carries cURus and TUV approvals, providing third-party validation of performance and safety characteristics. Moisture sensitivity level (MSL) rating of 1 (Unlimited) indicates no moisture-related handling restrictions.

Design Integration: Component selection should be based on application-specific electrical requirements including voltage rating, hold current (Ih), trip current (It), and thermal operating range. The 1206L600SLWR specifications (6V, 6A Ih, 12A It, -40°C to 85°C operating range) define the electrical and thermal envelope for this substitute.

Frequently Asked Questions (FAQ)

Q: Why is the PSR-28690-2 classified as obsolete?

A: The PSR-28690-2 has reached end-of-life status within Littelfuse's product portfolio. Obsolete classification indicates the component is no longer manufactured and existing inventory represents the final available supply.

Q: What makes the 1206L600SLWR a suitable substitute?

A: The 1206L600SLWR is manufactured by the same supplier (Littelfuse Inc.), operates within the same product category (polymeric PTC resettable fuse), maintains equivalent regulatory compliance (RoHS, ECCN, HTSUS), and is actively produced, ensuring supply continuity.

Q: Are there electrical parameter differences between the PSR-28690-2 and 1206L600SLWR?

A: The PSR-28690-2 detailed electrical specifications are not provided in the available documentation. The 1206L600SLWR is specified at 6V maximum voltage, 6A hold current, and 12A trip current. Application compatibility requires verification against original design specifications.

Q: What is the package difference between these components?

A: The 1206L600SLWR is specified as a surface mount component in 1206 (3216 Metric) package format with concave profile. Original PSR-28690-2 package specifications are not provided. Package compatibility must be confirmed for PCB layout and assembly process alignment.

Q: Does the 1206L600SLWR carry the same certifications?

A: The 1206L600SLWR carries cURus and TUV approvals. Original PSR-28690-2 approval agency information is not provided. Both components maintain RoHS compliance and identical trade classification codes (ECCN EAR99, HTSUS 8533.40.8070).

Q: What is the moisture sensitivity level (MSL) of the 1206L600SLWR?

A: The 1206L600SLWR carries MSL rating of 1 (Unlimited), indicating no moisture-related storage or handling restrictions apply to this component.

Q: Is the 1206L600SLWR REACH compliant?

A: The 1206L600SLWR is classified as REACH Unaffected, indicating the component does not contain substances of very high concern (SVHC) subject to REACH regulation.
