EPC1PI8 Equivalent & Substitute Parts

Part Overview

The EPC1PI8 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, making equivalent substitute parts necessary for ongoing system maintenance, repairs, and legacy product support. The part operates across dual voltage ranges (3V–3.6V and 4.5V–5.5V) and maintains industrial temperature specifications from -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC1PI8 is based on strict alignment of the following electrical and mechanical parameters:

• Memory Capacity: 1Mb (exact match required)
• Package Type: 8-DIP (0.300", 7.62mm) / 8-PDIP (physical and pin compatibility)
• Voltage Supply Ranges: 3V–3.6V and 4.5V–5.5V (dual-range operation)
• Operating Temperature Range: -40°C to 85°C (industrial specification)
• Mounting Configuration: Through-hole (PCB assembly compatibility)

The AT17LV010A-10PU meets all these criteria. While the EPC1PI8 uses OTP technology and the AT17LV010A-10PU uses Serial EEPROM technology, both devices share identical electrical operating parameters, package dimensions, and pin configurations, enabling functional substitution in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV010A-10PU is the qualified substitute for the EPC1PI8. Selection is justified on the following grounds:

• Electrical Compatibility: Identical voltage supply ranges and operating temperature specifications ensure direct functional replacement without circuit modification.
• Physical Compatibility: Matching 8-DIP package dimensions and pin configuration enable direct PCB mounting without layout changes.
• Product Availability: The AT17LV010A-10PU maintains active product status with confirmed inventory (1494 units), whereas the EPC1PI8 is obsolete.
• Regulatory Compliance: The AT17LV010A-10PU achieves ROHS3 compliance and maintains REACH unaffected status, supporting modern supply chain and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV010A-10PU replace the EPC1PI8 in existing designs?

A: Yes. Both devices share identical electrical operating parameters (voltage ranges, temperature specifications) and physical package dimensions (8-DIP, 0.300" pitch). Direct substitution is possible without circuit redesign.

Q: What is the difference between OTP and Serial EEPROM technologies in this context?

A: The EPC1PI8 uses OTP (One-Time Programmable) technology, while the AT17LV010A-10PU uses Serial EEPROM technology. From an electrical and mechanical standpoint, both are functionally equivalent for applications requiring 1Mb memory storage with the specified voltage and temperature ranges. Application-specific programming requirements should be evaluated independently.

Q: Are there pin-to-pin compatibility concerns?

A: No. Both devices use the 8-DIP (0.300", 7.62mm) package with identical pin configurations, ensuring direct PCB mounting compatibility.

Q: Does the RoHS compliance difference affect substitution?

A: The AT17LV010A-10PU's ROHS3 compliance provides regulatory advantage for new designs and modern supply chains. For legacy system repairs using the EPC1PI8, compliance requirements depend on application context and regional regulations.

Q: What inventory considerations apply?

A: The EPC1PI8 is obsolete with limited remaining stock (1287 units). The AT17LV010A-10PU is actively manufactured with confirmed availability (1494 units), supporting long-term supply chain reliability.
