EPC1PI8N Equivalent & Substitute Parts Reference

Part Overview

The EPC1PI8N is a 1Mbit OTP (One-Time Programmable) memory IC manufactured by Intel, housed in an 8-DIP through-hole package. This component is classified as obsolete, making substitute parts necessary for new designs and production continuity. The part operates across dual voltage ranges (3V–3.6V and 4.5V–5.5V) and supports industrial temperature specifications (-40°C to 85°C). Identifying compatible alternatives ensures design flexibility and supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC1PI8N is determined by strict alignment of the following parameters:

• Memory Capacity: 1Mb (exact match required)
• Package Type: 8-DIP through-hole configuration with 0.300" (7.62mm) pitch
• Voltage Compatibility: Support for both 3V–3.6V and 4.5V–5.5V supply ranges
• Temperature Range: -40°C to 85°C operational specification
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The AT17LV010A-10PU meets all critical electrical and mechanical parameters. While the AT17LV010A-10PU is classified as Serial EEPROM (versus OTP), it maintains functional equivalence through identical memory capacity, package geometry, voltage ranges, and temperature specifications. Both components are housed in 8-PDIP packages and support the same supply voltage windows.

Engineering Selection Recommendations

The AT17LV010A-10PU is the qualified substitute for the EPC1PI8N based on the following criteria:

• Electrical Compatibility: Identical memory capacity (1Mb), voltage supply ranges (3V–3.6V and 4.5V–5.5V), and operating temperature range (-40°C to 85°C) ensure direct functional replacement in circuit designs.
• Mechanical Compatibility: Both components use 8-DIP through-hole packages with matching 0.300" (7.62mm) pitch, enabling direct PCB footprint compatibility without layout modifications.
• Product Status: The AT17LV010A-10PU is active in production, providing reliable supply availability compared to the obsolete EPC1PI8N.
• Regulatory Compliance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications. The AT17LV010A-10PU carries ROHS3 compliance, meeting modern environmental standards.
• Moisture Sensitivity: Both components share MSL 1 (Unlimited) classification, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV010A-10PU directly replace the EPC1PI8N without PCB modifications?

A: Yes. Both components use identical 8-DIP through-hole packages with 0.300" (7.62mm) pitch. No PCB layout changes are required for mechanical or electrical integration.

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

A: OTP (One-Time Programmable) memory cannot be erased after programming. Serial EEPROM allows multiple program/erase cycles. The AT17LV010A-10PU's Serial EEPROM capability provides additional flexibility for development and field updates, though both support the same 1Mb capacity and voltage specifications.

Q: Are the voltage supply ranges identical between both parts?

A: Yes. Both the EPC1PI8N and AT17LV010A-10PU operate across 3V–3.6V and 4.5V–5.5V supply ranges, ensuring compatibility with existing power distribution designs.

Q: Does the AT17LV010A-10PU meet current environmental and regulatory requirements?

A: Yes. The AT17LV010A-10PU is ROHS3 compliant and maintains REACH Unaffected status, meeting current environmental regulations. Both parts share EAR99 ECCN classification for export control purposes.

Q: What is the temperature operating range for both components?

A: Both the EPC1PI8N and AT17LV010A-10PU operate from -40°C to 85°C, supporting industrial and commercial temperature specifications without derating.

Q: Is the AT17LV010A-10PU currently available in production quantities?

A: Yes. The AT17LV010A-10PU is classified as Active product status with documented inventory availability, unlike the obsolete EPC1PI8N.
