Substitute Part Grouping Explanation

Substitution of the 87016AYILF is determined by the following critical parameters:

Functional Compatibility Criteria:

Clock distribution and fanout buffering capability
Input signal type acceptance (minimum requirement: LVCMOS, LVPECL, or LVDS)
Output signal type provision (minimum requirement: LVCMOS or LVPECL)
Maximum frequency rating equal to or exceeding 250MHz
Surface mount packaging in 48-pin configuration

Electrical Compatibility Criteria:

Supply voltage range overlap with 2.375V ~ 3.465V
Operating temperature range covering -40°C ~ 85°C
Compliance with ROHS3 and REACH requirements

Mechanical Compatibility Criteria:

48-pin surface mount package (LQFP or equivalent footprint)
MSL rating of 3 or better

The substitute part 8SLVS1118NLGI meets these criteria as a Fanout Buffer (Distribution) IC with enhanced frequency capability (2GHz), compatible input/output signal types, overlapping supply voltage ranges, and equivalent environmental ratings.

Engineering Selection Recommendations

The 8SLVS1118NLGI is an active product from Renesas Electronics Corporation and represents a suitable substitute for the obsolete 87016AYILF. Both components maintain ROHS3 compliance and equivalent MSL ratings, ensuring regulatory and environmental compatibility.

The substitute part provides enhanced frequency capability (2GHz versus 250MHz) and maintains compatible supply voltage ranges across the specified operating temperature window. The increased output count (1:18 versus 2:16) and differential output capability (LVDS, LVPECL) offer functional advantages for modern clock distribution applications.

Package transition from 48-LQFP to 48-VFQFN Exposed Pad requires PCB layout verification to confirm footprint compatibility and thermal management requirements. The exposed pad in the VFQFN package provides improved thermal performance compared to the LQFP variant.

Frequently Asked Questions (FAQ)

Q: Can the 8SLVS1118NLGI directly replace the 87016AYILF without PCB modifications?

A: Package geometry differs between 48-LQFP and 48-VFQFN Exposed Pad. PCB footprint verification is required. Pin-to-pin compatibility must be confirmed against the respective datasheets before implementation.

Q: What are the key differences in signal output capability?

A: The 87016AYILF provides LVCMOS and LVTTL outputs, while the 8SLVS1118NLGI provides LVDS and LVPECL outputs. System signal integrity requirements must be evaluated to confirm output type compatibility with downstream components.

Q: Does the higher frequency rating of the substitute part affect compatibility?

A: The 2GHz maximum frequency of the 8SLVS1118NLGI exceeds the 250MHz requirement of the 87016AYILF. This provides operational margin and does not create incompatibility. System clock frequency requirements must remain within the 250MHz specification of the original design.

Q: Are supply voltage ranges compatible?

A: Both parts operate within overlapping voltage ranges. The 8SLVS1118NLGI specifies dual supply ranges (2.375V ~ 2.625V and 3.135V ~ 3.465V), while the 87016AYILF operates across 2.375V ~ 3.465V. Verify that system supply voltage falls within the substitute part's specified ranges.

Q: What is the significance of the exposed pad in the VFQFN package?

A: The exposed pad provides direct thermal connection to the PCB, improving heat dissipation compared to the LQFP package. PCB design must include appropriate thermal via patterns to utilize this feature effectively.

Q: Are both parts compliant with current regulatory requirements?

A: Both the 87016AYILF and 8SLVS1118NLGI are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.
