EPC1PC8 Equivalent & Substitute Parts

Part Overview

The EPC1PC8 is a 1Mb OTP (One-Time Programmable) memory integrated circuit manufactured by Intel, housed in an 8-DIP through-hole package. This device is classified as obsolete, reflecting its discontinuation from active production. The EPC1 series served as configuration memory for programmable logic devices and similar applications requiring non-volatile storage.

Due to its obsolete status and limited remaining inventory, identifying functionally equivalent substitute parts is essential for system redesign, legacy product support, and procurement continuity. Substitute parts must maintain compatibility across memory capacity, package form factor, voltage supply ranges, and operating temperature specifications.

Substitute Part Grouping Explanation

The AT17LV010A-10PU from Microchip Technology qualifies as a functional substitute for the EPC1PC8 based on the following alignment of critical parameters:

Matching Parameters:

• Memory Size: Both devices provide 1Mb capacity
• Package / Case: Both use 8-DIP (0.300", 7.62mm) through-hole configuration
• Mounting Type: Both employ through-hole mounting
• Voltage Supply: AT17LV010A-10PU supports 3V ~ 3.6V and 4.5V ~ 5.5V, providing overlap with the EPC1PC8 range of 3V ~ 3.6V and 4.75V ~ 5.25V
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• REACH Status: Both classified as REACH Unaffected

Functional Difference: The AT17LV010A-10PU implements Serial EEPROM technology rather than OTP. This represents a functional enhancement, as EEPROM devices support multiple program/erase cycles, providing greater flexibility than one-time programmable devices. Systems designed for OTP operation remain compatible with EEPROM substitutes.

Operating Temperature Consideration: The substitute part supports -40°C ~ 85°C, exceeding the EPC1PC8 range of 0°C ~ 70°C. This provides enhanced environmental capability for extended temperature applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EPC1PC8 is obsolete with no active manufacturing. The AT17LV010A-10PU is actively produced by Microchip Technology, ensuring long-term availability and supply chain stability for new designs and legacy product support.

Compliance and Certification: The AT17LV010A-10PU meets ROHS3 compliance standards, whereas the EPC1PC8 is non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the substitute part satisfies current regulatory frameworks.

Electrical Compatibility: Both devices operate within overlapping voltage supply ranges. The substitute's extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) provides additional environmental margin for applications requiring enhanced thermal performance.

Physical and Functional Compatibility: Identical 8-DIP package geometry and through-hole mounting ensure direct PCB compatibility without layout modifications. The transition from OTP to Serial EEPROM technology maintains functional compatibility while enabling multiple program/erase cycles if required by application updates.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV010A-10PU directly replace the EPC1PC8 on existing PCBs?

A: Yes. Both devices use identical 8-DIP (0.300", 7.62mm) through-hole packaging. No PCB layout modifications are required for physical substitution.

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

A: OTP (One-Time Programmable) devices can be programmed once and retain data permanently. Serial EEPROM devices support multiple program/erase cycles, enabling data updates and reprogramming. Systems designed for OTP operation remain fully compatible with EEPROM substitutes.

Q: Are the voltage supply ranges compatible?

A: The EPC1PC8 operates at 3V ~ 3.6V and 4.75V ~ 5.25V. The AT17LV010A-10PU operates at 3V ~ 3.6V and 4.5V ~ 5.5V. Both ranges overlap at 3V ~ 3.6V and 4.75V ~ 5.25V, ensuring compatibility with standard 3.3V and 5V supply systems.

Q: Does the substitute part meet current environmental compliance standards?

A: Yes. The AT17LV010A-10PU is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The EPC1PC8 is RoHS non-compliant, reflecting its obsolete status.

Q: What is the operating temperature range difference?

A: The EPC1PC8 operates from 0°C to 70°C. The AT17LV010A-10PU operates from -40°C to 85°C, providing extended environmental capability for applications requiring enhanced thermal performance or operation in extreme temperature conditions.

Q: Is the AT17LV010A-10PU actively manufactured?

A: Yes. The AT17LV010A-10PU is classified as active product status with Microchip Technology, ensuring ongoing availability and supply chain continuity. The EPC1PC8 is obsolete and no longer manufactured.
