EPC1441PC8 Equivalent & Substitute Parts

Part Overview

The EPC1441PC8 is an obsolete configuration device manufactured by Intel, designed for 400Kbit memory applications in 8-DIP through-hole packaging. This part operates across dual voltage ranges (3V–3.6V and 4.75V–5.25V) and is classified as an OTP (One-Time Programmable) memory device. Due to its obsolete product status and limited remaining inventory, identifying functionally compatible substitute components is essential for system redesign, legacy system maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC1441PC8 is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-DIP (0.300", 7.62mm) through-hole packaging to ensure PCB footprint and socket compatibility.
• Voltage Supply Range: The substitute must operate within overlapping voltage windows. The EPC1441PC8 operates at 3V–3.6V and 4.75V–5.25V; the substitute must support at least one of these ranges.
• Memory Architecture: The substitute must provide equivalent or greater memory capacity (minimum 440kb) and support programmable memory functionality.
• Mounting Type: Through-hole mounting is required for direct replacement in legacy PCB designs.

The AT17LV512A-10PU meets these criteria through identical 8-DIP packaging, overlapping voltage support (3V–3.6V range), and programmable memory architecture with 512kb capacity.

Engineering Selection Recommendations

AT17LV512A-10PU is the qualified substitute for EPC1441PC8 based on the following engineering criteria:

• Package Equivalence: Identical 8-DIP through-hole packaging ensures direct PCB compatibility without layout modifications.
• Voltage Compatibility: The 3V–3.6V operating range is fully supported. Applications requiring the 4.75V–5.25V range must verify circuit-level compatibility with the substitute's 4.5V–5.5V specification.
• Memory Capacity: The 512kb capacity exceeds the original 440kb requirement, providing functional headroom for legacy applications.
• Active Product Status: The substitute is in active production with verified inventory availability, ensuring long-term supply chain reliability.
• Compliance Advantage: ROHS3 compliance and REACH unaffected status make this substitute suitable for modern manufacturing and regulatory environments, whereas the original part is non-compliant.

Frequently Asked Questions (FAQ)

Q: Can AT17LV512A-10PU be used as a direct drop-in replacement for EPC1441PC8?

A: Yes, for applications operating in the 3V–3.6V range with identical 8-DIP through-hole PCB footprints. The substitute's 512kb memory capacity is compatible with systems designed for 440kb. Applications using the 4.75V–5.25V range require circuit verification, as the substitute operates at 4.5V–5.5V.

Q: What is the difference between OTP and Serial EEPROM memory types?

A: OTP (One-Time Programmable) memory can be written once and is permanent. Serial EEPROM can be reprogrammed multiple times. The AT17LV512A-10PU's Serial EEPROM architecture provides greater flexibility for development and field updates compared to the original OTP design.

Q: Are there any RoHS or environmental compliance considerations?

A: The EPC1441PC8 is RoHS non-compliant. The AT17LV512A-10PU is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to modern environmental regulations.

Q: Does the substitute support the full operating temperature range of the original part?

A: The substitute supports an extended range (−40°C–85°C) compared to the original (0°C–70°C). Applications operating within the original 0°C–70°C window are fully compatible.

Q: What packaging options are available for the substitute?

A: The AT17LV512A-10PU is supplied in tube packaging. The 8-DIP form factor is identical to the original part.
