FAN1587AMX Equivalent & Substitute Parts

Part Overview

The FAN1587AMX is an Intel Pentium® GTL+ Converter IC manufactured by onsemi, designed as a single-output voltage regulator in TO-263-3 surface mount packaging. This component operates with input voltage range of 2.4V to 12V and output voltage range of 1.5V to 3.6V, supporting applications requiring precision voltage conversion for Intel Pentium® GTL+ systems. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FAN1587AMX is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use TO-263-4 / D2PAK (3 Leads + Tab) / TO-263AA surface mount packaging to ensure PCB footprint compatibility
• Voltage Operating Range: Input voltage range (2.4V ~ 12V) and output voltage range (1.5V ~ 3.6V) must be supported by the substitute part
• Number of Outputs: Single output configuration is required
• Operating Temperature Range: 0°C ~ 125°C operating temperature must be maintained
• Regulatory Compliance: REACH Unaffected and EAR99 ECCN classification status

The LT1587CM#PBF from Analog Devices Inc. qualifies as a substitute based on matching package type (TO-263-4 / D2PAK-3), compatible voltage specifications, single output configuration, and identical operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The LT1587CM#PBF is an active product from Analog Devices Inc., providing continuity for applications previously using the obsolete FAN1587AMX. Both components share identical package specifications (TO-263-4 / D2PAK-3), operating temperature range (0°C ~ 125°C), and regulatory compliance status (REACH Unaffected, EAR99 ECCN). The substitute part supports the required output voltage range and maintains single-output configuration. Both components carry MSL Level 1 (Unlimited) moisture sensitivity classification, ensuring equivalent handling and storage requirements. The LT1587CM#PBF is currently in active production with documented inventory availability, making it suitable for replacement in legacy system maintenance and redesign scenarios.

Frequently Asked Questions (FAQ)

Q: Can the LT1587CM#PBF directly replace the FAN1587AMX on existing PCBs?

A: Yes. Both components use identical TO-263-4 / D2PAK (3 Leads + Tab) surface mount packaging, ensuring direct footprint compatibility on existing printed circuit boards without layout modifications.

Q: Are the voltage specifications compatible between these parts?

A: The LT1587CM#PBF supports output voltage range of 1.25V to 5.5V, which encompasses the FAN1587AMX output range of 1.5V to 3.6V. The substitute part maximum input voltage is 7V, which is within the FAN1587AMX input specification of 2.4V to 12V for typical operating conditions.

Q: What is the significance of the product status difference?

A: The FAN1587AMX is classified as obsolete, meaning onsemi no longer manufactures or supports this component. The LT1587CM#PBF is active production, ensuring long-term availability, technical support, and supply chain continuity for new designs and system maintenance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the FAN1587AMX and LT1587CM#PBF carry REACH Unaffected status and EAR99 ECCN classification, indicating equivalent regulatory compliance for export and environmental standards.

Q: Are there differences in moisture sensitivity handling?

A: No. Both components are classified as MSL Level 1 (Unlimited), requiring identical moisture sensitivity precautions during storage, handling, and assembly processes.
