Substitute Part Grouping Explanation

Substitution of the 841604ALMILF requires evaluation of functional and electrical compatibility based on the following criteria:

Functional Compatibility: The substitute part must operate as a Clock Generator with PLL capability and support the same input signal types (LVCMOS, LVTTL, Crystal) and output signal types (HCSL).

Electrical Compatibility: The substitute part must support the 3.135V ~ 3.465V supply voltage range of the original part and maintain the same operating temperature range (-40°C ~ 85°C).

Frequency Performance: The substitute part must support a maximum frequency equal to or greater than 125MHz to accommodate existing system clock requirements.

Output Configuration: The substitute part must provide differential output capability (HCSL or compatible differential output standards) to maintain signal integrity in the target application.

Packaging and Mounting: Surface mount packaging is required. Package dimensions and pin count may differ from the original 28-TSSOP, requiring PCB layout evaluation.

Engineering Selection Recommendations

9FGV1004C001NBGI as Primary Substitute:

The 9FGV1004C001NBGI is manufactured by Renesas Electronics Corporation and carries Active product status, ensuring long-term availability and supply chain continuity. This device is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

The 9FGV1004C001NBGI supports the 3.135V ~ 3.465V supply voltage range required by the 841604ALMILF and maintains the same operating temperature specification (-40°C ~ 85°C). The maximum frequency of 325MHz exceeds the 125MHz requirement of the original part, providing operational headroom.

Input compatibility is maintained through support for LVCMOS and Crystal inputs. Output compatibility is enhanced, as the 9FGV1004C001NBGI provides HCSL output alongside additional output format options (CML, LP-HCSL, LVCMOS, LVDS, LVPECL).

The package change from 28-TSSOP to 24-WFQFN Exposed Pad requires PCB layout modification. The 24-WFQFN package (4x4) is a standard surface mount format with reduced footprint compared to the original 28-TSSOP.

The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 9FGV1004C001NBGI directly replace the 841604ALMILF without PCB modifications?

A: No. The package format differs (24-WFQFN versus 28-TSSOP), requiring PCB layout changes. Pin assignments and signal routing must be re-evaluated during the substitution process.

Q: Does the 9FGV1004C001NBGI support the same input signal types as the 841604ALMILF?

A: The 9FGV1004C001NBGI supports LVCMOS and Crystal inputs, which are common to the 841604ALMILF. The 9FGV1004C001NBGI additionally supports HCSL and LVDS inputs, providing expanded input flexibility.

Q: Is the 9FGV1004C001NBGI compatible with the 3.3V supply voltage of the 841604ALMILF?

A: Yes. The 9FGV1004C001NBGI supports the 3.135V ~ 3.465V supply voltage range, which encompasses the 3.3V nominal supply voltage of the original part.

Q: What is the significance of the higher maximum frequency (325MHz) of the 9FGV1004C001NBGI?

A: The higher frequency specification provides operational margin above the 125MHz requirement of the 841604ALMILF. This allows the substitute part to support existing clock distribution requirements without frequency limitations.

Q: Does the 9FGV1004C001NBGI provide HCSL output as specified in the 841604ALMILF?

A: Yes. The 9FGV1004C001NBGI provides HCSL output alongside additional output format options. HCSL output compatibility is maintained.

Q: What is the difference between the 28-TSSOP and 24-WFQFN packages?

A: The 28-TSSOP is a thin shrink small outline package with 28 pins in a 0.240" width. The 24-WFQFN is a quad flat no-lead package with 24 pins in a 4x4mm footprint. Both are surface mount packages, but the pin count, pitch, and footprint differ significantly.

Q: Is the 9FGV1004C001NBGI suitable for applications requiring long-term supply availability?

A: Yes. The 9FGV1004C001NBGI carries Active product status, indicating ongoing manufacturing and distribution support. This contrasts with the Obsolete status of the 841604ALMILF.

Q: Are there environmental compliance differences between the two parts?

A: The 9FGV1004C001NBGI is RoHS3 Compliant and REACH Unaffected. The 841604ALMILF is classified as Obsolete, with no current compliance certifications listed. The substitute part meets current environmental regulations.
