PI6C2409-1HWEX Equivalent & Substitute Parts

Part Overview

The PI6C2409-1HWEX is a Zero Delay Buffer IC manufactured by Diodes Incorporated, designed for clock and timing applications requiring 133MHz operation. This device features a 1:9 input-to-output ratio with PLL bypass capability and TTL-compatible signal levels. The part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI6C2409-1HWEX is based on the following critical parameters that must remain consistent:

• Device type: Zero Delay Buffer
• Maximum frequency: 133MHz
• Input-to-output ratio: 1:9
• PLL with bypass capability
• Package: 16-SOIC (0.154", 3.90mm Width)
• Surface mount configuration
• Operating temperature range: 0°C to 70°C
• RoHS3 compliance

The substitute parts identified (23S09T-1DCG and 23S09T-1DCG8) maintain these core electrical and mechanical specifications. Both are manufactured by Renesas Electronics Corporation and carry active product status, distinguishing them from the obsolete PI6C2409-1HWEX.

Parameter Comparison

Engineering Selection Recommendations

Both 23S09T-1DCG and 23S09T-1DCG8 are suitable substitutes for the obsolete PI6C2409-1HWEX based on functional equivalence and compliance status. Both substitute parts carry active product status from Renesas Electronics Corporation and maintain ROHS3 compliance.

The primary distinction between the two substitutes is packaging format: 23S09T-1DCG is supplied in Tube packaging, while 23S09T-1DCG8 is supplied in Tape & Reel (TR) format. Selection between these two should be based on procurement and assembly requirements.

Note that the substitute parts operate at a lower supply voltage range (2.3V to 2.7V) compared to the original part (3.0V to 3.6V). Additionally, the substitute parts feature LVTTL input compatibility and dual output capability (CMOS and LVTTL), providing enhanced signal level flexibility. The moisture sensitivity level differs, with substitutes rated at MSL 3 (168 Hours) versus the original MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can 23S09T-1DCG and 23S09T-1DCG8 be used interchangeably with PI6C2409-1HWEX?

A: Both Renesas parts are functionally equivalent in terms of core timing specifications (133MHz, 1:9 ratio, PLL with bypass, 16-SOIC package). The primary difference is packaging format (Tube versus Tape & Reel). Selection depends on assembly and procurement workflow requirements.

Q: What is the impact of the different supply voltage ranges?

A: The PI6C2409-1HWEX operates at 3.0V to 3.6V, while the substitute parts operate at 2.3V to 2.7V. Circuit design must accommodate the lower voltage range of the substitute parts. Verify that system power supply specifications align with the 2.3V to 2.7V requirement.

Q: Are there signal level compatibility considerations?

A: The original part provides TTL input and output. The substitute parts accept LVTTL input and provide both CMOS and LVTTL output options. LVTTL is a lower-voltage variant of TTL and is generally compatible with TTL-level signals in most applications, but system-level signal integrity analysis is necessary for critical timing paths.

Q: What does the difference in Moisture Sensitivity Level mean?

A: The original part has MSL 1 (Unlimited shelf life under controlled conditions), while substitutes have MSL 3 (168-hour shelf life limit). This affects storage and handling procedures. Parts with MSL 3 require more stringent moisture control during storage and have a defined bake-out requirement before reflow soldering if moisture absorption occurs.

Q: Which substitute part should be selected for new production?

A: Both parts are active and compliant. Choose 23S09T-1DCG8 (Tape & Reel) for high-volume automated assembly. Choose 23S09T-1DCG (Tube) if manual or lower-volume assembly processes are used.
