EPC1441LC20 Equivalent & Substitute Parts

Part Overview

The EPC1441LC20 is an OTP (One-Time Programmable) configuration device with 440kb memory capacity, manufactured by Intel in a 20-PLCC surface mount package. This part is classified as obsolete, making substitute components necessary for new designs and ongoing production support. The device operates across dual voltage ranges (3V–3.6V and 4.75V–5.25V) and is suitable for applications requiring non-volatile memory configuration storage in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC1441LC20 is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 20-PLCC (9×9) surface mount package to ensure mechanical and electrical fit on existing PCBs.
• Voltage Supply Ranges: The substitute must support overlapping or compatible voltage ranges. The EPC1441LC20 operates at 3V–3.6V and 4.75V–5.25V; substitutes must accommodate these ranges or provide equivalent dual-voltage operation.
• Memory Type and Capacity: The substitute must provide non-volatile memory functionality with capacity at or above 440kb to maintain system requirements.
• Mounting Type: Surface mount technology must be preserved for manufacturing compatibility.
• Operating Temperature Range: The substitute must support the required temperature envelope or exceed it.

The AT17LV512A-10JU meets these substitution criteria through identical package geometry, compatible voltage operation, and superior memory capacity (512kb), while maintaining surface mount compatibility.

Engineering Selection Recommendations

The AT17LV512A-10JU is the qualified substitute for the EPC1441LC20 based on the following engineering criteria:

• Product Status Alignment: The EPC1441LC20 is obsolete; the AT17LV512A-10JU is active and in production, ensuring long-term availability and supply chain stability.
• Compliance Advantage: The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This is significant for applications subject to environmental regulations.
• Package Compatibility: Identical 20-PLCC (9×9) package ensures direct mechanical and electrical compatibility without PCB redesign.
• Voltage Operation: The substitute supports the required 3V–3.6V range and extends the upper range to 5.5V (versus 5.25V), providing broader system flexibility.
• Temperature Range Extension: The substitute operates from −40°C to 85°C, exceeding the original 0°C–70°C range and supporting wider deployment scenarios.
• Memory Capacity: The 512kb capacity exceeds the 440kb requirement, providing additional headroom for configuration storage.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV512A-10JU be used as a direct replacement for the EPC1441LC20?

A: Yes, within the constraints of the 20-PLCC package and voltage supply ranges. Both devices use identical package geometry (20-PLCC, 9×9) and support overlapping voltage operation. However, the AT17LV512A-10JU is a Serial EEPROM, whereas the EPC1441LC20 is OTP; this functional difference requires interface verification at the system level.

Q: What are the key differences between these parts?

A: The primary differences are programmable type (OTP versus Serial EEPROM), memory capacity (440kb versus 512kb), operating temperature range (0°C–70°C versus −40°C–85°C), and compliance status (RoHS non-compliant versus ROHS3 compliant). Package and voltage ranges are compatible.

Q: Does the substitute require PCB modifications?

A: No. The AT17LV512A-10JU uses the same 20-PLCC (9×9) package footprint, eliminating the need for PCB layout changes. Electrical interface compatibility must be confirmed based on system requirements.

Q: What is the moisture sensitivity difference?

A: The EPC1441LC20 has MSL 1 (unlimited shelf life), while the AT17LV512A-10JU has MSL 2 (1-year shelf life). This affects storage and handling procedures; the substitute requires more controlled storage conditions.

Q: Is the higher memory capacity of the substitute a concern?

A: No. The 512kb capacity of the AT17LV512A-10JU exceeds the 440kb requirement, providing additional storage margin without adverse effects on system operation.
