PI49FCT3807CSE Equivalent & Substitute Parts

Part Overview

The PI49FCT3807CSE is a Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated, designed for 1:10 clock distribution at frequencies up to 100 MHz. This component operates with supply voltages between 3V and 3.6V and is housed in a 20-SOIC package. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance characteristics and physical packaging to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the PI49FCT3807CSE is based on strict equivalence across the following critical parameters:

Functional Type: Fanout Buffer (Distribution) with 1:10 input-to-output ratio
Frequency Performance: Maximum operating frequency of 100 MHz
Supply Voltage Range: 3V to 3.6V operation
Package Specification: 20-SOIC (0.295", 7.50mm Width) surface mount
Electrical Compatibility: CMOS/TTL input and output logic levels
Compliance Standards: ROHS3 compliance and MSL Level 1

All substitute parts listed are manufactured by Renesas Electronics Corporation under the 74FCT3807 base product number. These parts are available in two packaging formats (Tube and Tape & Reel) and two temperature grades (0°C ~ 70°C and -40°C ~ 85°C). Selection between substitutes depends on specific application requirements for operating temperature range and packaging format.

Engineering Selection Recommendations

All listed Renesas 74FCT3807 variants are active production parts with ROHS3 compliance and MSL Level 1 rating, making them suitable replacements for the obsolete PI49FCT3807CSE. Selection criteria are determined by two factors:

Operating Temperature Range: Applications requiring extended temperature operation from -40°C to 85°C must use parts with the "I" suffix designation (74FCT3807ASOGI, 74FCT3807ASOGI8, 74FCT3807SOGI, 74FCT3807SOGI8). Applications limited to 0°C to 70°C operation may use standard temperature variants (74FCT3807ASOG, 74FCT3807ASOG8, 74FCT3807SOG, 74FCT3807SOG8).

Packaging Format: Tube packaging is suitable for manual assembly and lower-volume applications. Tape & Reel (TR) packaging with the "8" suffix is specified for automated pick-and-place assembly and higher-volume production runs.

Frequently Asked Questions (FAQ)

Q: Can I use a 74FCT3807 part with 0°C to 70°C temperature rating in an application requiring -40°C to 85°C operation?

A: No. Temperature rating is a critical specification. Parts rated for 0°C to 70°C operation are not qualified for extended temperature ranges. Use only parts with the "I" suffix (74FCT3807ASOGI, 74FCT3807ASOGI8, 74FCT3807SOGI, 74FCT3807SOGI8) for -40°C to 85°C applications.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual component handling and lower-volume applications. Tape & Reel (TR) packaging, identified by the "8" suffix, is designed for automated assembly equipment and high-volume production. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are all 74FCT3807 variants pin-compatible with the PI49FCT3807CSE?

A: Yes. All listed substitutes maintain the same 20-SOIC package footprint (0.295", 7.50mm Width) and pinout configuration, ensuring direct physical and electrical compatibility.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all variants.

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

A: For new designs, select based on your specific requirements: use extended temperature variants (with "I" suffix) if operating conditions span -40°C to 85°C, and use Tape & Reel packaging (with "8" suffix) for automated assembly. The 74FCT3807ASOGI8 provides both extended temperature range and automated assembly packaging.
