Substitute Part Grouping Explanation
Substitution of the 87016AYLF is determined by the following critical parameters:
- Functional Type: Clock distribution and fanout buffering capability
- Frequency Performance: Maximum operating frequency must support or exceed 250MHz
- Package Compatibility: 48-pin surface mount package (LQFP or equivalent footprint)
- Signal Compatibility: Input and output signal standards must align with system requirements
- Supply Voltage: Operating voltage range must overlap with or encompass 3.135V ~ 3.465V
- Temperature Range: Operating temperature capability must cover 0°C ~ 85°C minimum
- Compliance: RoHS3 compliance and MSL rating must be maintained
The identified substitute, Renesas Electronics 8SLVS1118NLGI, is a Clock Fanout Buffer (Distribution) IC that meets these substitution criteria through compatible packaging, overlapping supply voltage specifications, and equivalent compliance certifications.

Engineering Selection Recommendations
The 8SLVS1118NLGI is identified as a manufacturer-recommended substitute for the obsolete 87016AYLF. Selection of this substitute is supported by the following factors:
- Active Product Status: The substitute is an active product from the same manufacturer, ensuring ongoing availability and support
- Compliance Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory and handling requirements
- Voltage Compatibility: The substitute's dual supply voltage range (2.375V ~ 2.625V and 3.135V ~ 3.465V) encompasses the original part's operating voltage
- Temperature Coverage: The substitute's extended operating temperature range (-40°C ~ 85°C) exceeds the original specification
- Frequency Capability: The substitute's 2 GHz maximum frequency significantly exceeds the 250MHz requirement
- Package Transition: Migration from 48-LQFP to 48-VFQFN requires PCB layout and footprint verification
Frequently Asked Questions (FAQ)
Q: Can the 8SLVS1118NLGI directly replace the 87016AYLF without PCB modifications?
A: Package footprints differ between the two parts (48-LQFP versus 48-VFQFN Exposed Pad). PCB layout modifications are required. Pin-to-pin compatibility must be verified against detailed datasheets before implementation.
Q: What are the key differences in functional capability between these parts?
A: The 87016AYLF provides a 2:16 input-to-output ratio with multiple input signal type support (HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL). The 8SLVS1118NLGI provides a 1:18 ratio with LVDS and LVPECL output capability. System signal requirements must be evaluated for compatibility.
Q: Are both parts suitable for the same supply voltage?
A: The 3.135V ~ 3.465V supply range is common to both parts. The substitute additionally supports 2.375V ~ 2.625V operation, providing expanded voltage flexibility.
Q: What is the significance of the exposed pad in the 48-VFQFN package?
A: The exposed pad provides enhanced thermal dissipation compared to the LQFP package. PCB design must include appropriate thermal via patterns and copper area for proper heat management.
Q: Are moisture sensitivity levels equivalent between the two parts?
A: Both parts carry MSL rating 3 (168 Hours), indicating identical moisture handling and storage requirements.
