EP3C5F256C6 Equivalent & Substitute Parts

Part Overview

The EP3C5F256C6 is a Cyclone® III Field Programmable Gate Array (FPGA) manufactured by Intel, designed for embedded applications requiring 182 I/O pins and 5,136 logic elements. This device is currently in active production status and is widely used in digital signal processing, communications, and industrial control applications. Identifying equivalent and substitute parts is essential for supply chain continuity, inventory optimization, and project timeline management when the primary part number becomes unavailable or when alternative packaging configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EP3C5F256C6 is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must be Intel Cyclone® III devices to ensure architectural compatibility and design tool support
• Logic Resources: Identical logic element count (5,136), LAB/CLB count (321), and RAM capacity (423,936 bits) are mandatory for functional equivalence
• I/O Configuration: The 182 I/O pin count must remain constant across all substitute parts
• Electrical Specifications: Supply voltage range (1.15V ~ 1.25V) and operating temperature range (0°C ~ 85°C) must be identical
• Package and Mounting: The 256-LBGA package format and surface mount technology must be preserved
• Packaging Format: Differences in shipping and storage packaging (tube, tray, or reel) do not affect functional equivalence but may impact procurement and handling procedures

The EP3C5F256C6N qualifies as a direct substitute based on complete alignment with all electrical, mechanical, and functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The EP3C5F256C6N is a direct functional equivalent to the EP3C5F256C6 across all electrical, logical, and mechanical specifications. Both devices share identical core architecture, I/O configuration, and performance characteristics.

A key distinction exists in compliance certification: the EP3C5F256C6N carries RoHS Compliant status, while the EP3C5F256C6 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the EP3C5F256C6N is the appropriate selection. For applications without such constraints, either part number is functionally interchangeable.

The EP3C5F256C6N is supplied in tray packaging, which may differ from the original part's packaging format. This distinction affects only procurement, storage, and handling procedures and does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can EP3C5F256C6N be used as a direct replacement for EP3C5F256C6 in existing designs?

A: Yes. Both devices are functionally identical across all electrical, logical, and mechanical parameters. No design modifications are required. The only consideration is RoHS compliance status; if your application or customer requirements mandate RoHS compliance, the EP3C5F256C6N is the appropriate choice.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance certification. The EP3C5F256C6N is RoHS Compliant, while the EP3C5F256C6 is RoHS non-compliant. Both devices have identical core specifications: 5,136 logic elements, 182 I/O pins, 423,936 RAM bits, 1.15V–1.25V supply voltage, and 256-LBGA package format.

Q: Does packaging format affect compatibility?

A: No. Packaging format (tube, tray, or reel) affects only procurement, storage, and handling procedures. It does not impact electrical performance, functionality, or PCB integration. Both part numbers use the same 256-LBGA (17x17) package for mounting.

Q: Are there any temperature or voltage differences between these parts?

A: No. Both devices operate across the identical temperature range (0°C ~ 85°C junction temperature) and supply voltage range (1.15V ~ 1.25V). They are fully interchangeable from an electrical specification standpoint.

Q: Which part should I select for a new design?

A: If RoHS compliance is required by your application, customer, or regulatory environment, select EP3C5F256C6N. If RoHS compliance is not a requirement, either part number is suitable. Both are in active production status and functionally equivalent.
