89HT0816PYBBC Signal Retimer Interface Equivalent & Substitute Parts

Part Overview

The 89HT0816PYBBC is a specialized signal retimer interface IC manufactured by Renesas Electronics Corporation, housed in a 196-CABGA (15x15) package. This component is classified as an obsolete product, necessitating the identification of active alternative components for new designs and ongoing system support. Signal retimer interfaces are critical for maintaining signal integrity in high-speed data transmission applications, particularly where I2C communication protocols are employed. The obsolete status of this part requires engineers to evaluate functionally equivalent alternatives from active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 89HT0816PYBBC is determined by the following critical parameters:

• Interface Protocol: I2C compatibility is the primary functional requirement
• Category: Specialized interface IC functionality
• Mounting Type: Surface mount technology for PCB integration
• Product Status: Active alternatives required due to obsolescence
• Compliance & Certifications: RoHS3 compliance and REACH status for regulatory adherence

The substitute parts listed below maintain I2C interface capability and active product status. However, package form factors differ significantly from the original 196-CABGA, reflecting the evolution of interface IC design toward smaller, more efficient packages. Substitution requires design-level evaluation of physical constraints and pin configuration compatibility.

Parameter Comparison

Engineering Selection Recommendations

LTC4316CDD#PBF and LTC4317IDHC#TRPBF are the primary candidates for I2C-based signal retimer applications. Both parts maintain direct I2C interface compatibility, feature active product status, and carry ROHS3 compliance with unlimited MSL ratings. The LTC4316 operates in a 10-DFN package, while the LTC4317 provides expanded functionality in a 16-DFN package. Both support voltage ranges of 2.25V to 5.5V.

MAX14502AETL+ offers I2C and 2-Wire Serial interface capability with the lowest supply voltage range (1.8V ~ 3.3V), suitable for low-power applications. This part is available in high inventory (21,242 units) and operates in a 40-TQFN package.

LTC4305CGN#TRPBF provides SMBus (2-Wire/I2C) compatibility with a wider supply voltage range (2.2V ~ 5.5V) in a 16-SSOP surface mount package.

5962-8962902LX and Z8523008PEG are through-hole alternatives for legacy system designs. The 5962-8962902LX operates at ±5V with a 24-CDIP package, while the Z8523008PEG functions at 4.5V ~ 5.5V in a 40-DIP package.

All substitute parts carry ROHS3 compliance and REACH unaffected or compliant status, meeting modern regulatory requirements. Selection should prioritize package compatibility with existing PCB layouts and voltage supply constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 89HT0816PYBBC be directly replaced with any of these substitute parts?

A: Direct pin-for-pin replacement is not possible due to significant package differences. The original part uses a 196-CABGA package, while substitutes range from 10-DFN to 40-DIP packages. Design-level evaluation of pinout, signal routing, and PCB layout is required for each substitution candidate.

Q: Which substitute part maintains the closest I2C interface compatibility?

A: LTC4316CDD#PBF and LTC4317IDHC#TRPBF both provide dedicated I2C interface support with active product status and modern compliance certifications. These are the recommended choices for I2C-dependent applications.

Q: What is the significance of the MSL rating difference?

A: The original part carries MSL 4 (72 Hours), indicating moisture sensitivity requiring controlled storage and handling. All substitute parts feature MSL 1 (Unlimited), eliminating moisture sensitivity constraints and simplifying supply chain management and storage requirements.

Q: Are through-hole alternatives viable for new designs?

A: Through-hole packages (5962-8962902LX and Z8523008PEG) are suitable for legacy system maintenance and applications where through-hole technology is specified. For new designs, surface mount alternatives (LTC4316CDD#PBF, LTC4317IDHC#TRPBF, MAX14502AETL+, LTC4305CGN#TRPBF) are preferred due to modern manufacturing standards and board density optimization.

Q: What voltage supply considerations apply to substitution?

A: The original part does not specify supply voltage. Substitute parts operate across ranges from 1.8V ~ 3.3V (MAX14502AETL+) to ±5V (5962-8962902LX). Selection must align with the target system's power supply architecture and signal voltage levels.

Q: Do all substitute parts meet current regulatory compliance standards?

A: Yes. All substitute parts carry ROHS3 compliance and either REACH Unaffected or REACH Compliant status, meeting current environmental and regulatory requirements for component procurement and system deployment.
