Engineering Selection Recommendations

Primary Recommendation: R5F100GLDNA#40

The R5F100GLDNA#40 is designated as the manufacturer-recommended substitute. This part maintains complete electrical and functional equivalence to the R5F100GLDNA#W0 while offering Active product status. The R5F100GLDNA#40 is supplied in Tape & Reel packaging format and carries ROHS3 compliance certification with MSL rating of 3 (168 Hours). Current inventory availability is 866 units.

Secondary Recommendations: R5F100GLANA#00, R5F100GLANA#40, R5F100GLDNA#00

All three parametric equivalent parts provide identical electrical specifications and mechanical compatibility. These parts are classified as Active products with ROHS3 compliance and MSL 3 (168 Hours) ratings. Selection among these alternatives is determined by packaging requirements and inventory availability:

R5F100GLANA#00: 663 units in stock
R5F100GLANA#40: 1007 units in stock
R5F100GLDNA#00: 1014 units in stock

Compliance Considerations

All substitute parts carry REACH Unaffected status and ECCN classification 3A991A2. The transition from the Obsolete R5F100GLDNA#W0 to Active alternatives ensures compliance with current regulatory requirements and supply chain sustainability.

Frequently Asked Questions (FAQ)

Q: Can the R5F100GLDNA#W0 be directly replaced with R5F100GLDNA#40?

A: Yes. The R5F100GLDNA#40 provides complete electrical and mechanical equivalence. All core parameters including processor architecture, memory configuration, operating frequency, voltage range, I/O count, and peripheral set are identical. The primary difference is product status (Active versus Obsolete) and packaging format (Tape & Reel).

Q: What is the difference between the suffix designations (#W0, #00, #40)?

A: The suffix designations indicate packaging and tape configuration variants. The #W0 designation on the main part indicates a specific packaging format that is now obsolete. The #00 and #40 suffixes on substitute parts indicate alternative tape and reel configurations. These variations do not affect electrical performance or functional capability.

Q: Are all substitute parts pin-compatible with the original R5F100GLDNA#W0?

A: Yes. All substitute parts utilize the identical 48-pin HWQFN (7x7) package with 48-WFQFN Exposed Pad configuration. Pin count, pin assignment, and footprint dimensions are identical across all parts listed.

Q: What is the significance of the ROHS3 compliance on substitute parts?

A: ROHS3 compliance indicates that substitute parts meet current Restriction of Hazardous Substances regulations. The original R5F100GLDNA#W0 does not specify RoHS status due to its Obsolete classification. Substitute parts with ROHS3 compliance ensure compliance with current environmental and regulatory standards for new production.

Q: How do the parametric equivalent parts (GLANA series) differ from the manufacturer-recommended part (GLDNA#40)?

A: The GLANA series parts (R5F100GLANA#00 and R5F100GLANA#40) are parametric equivalents that maintain identical electrical specifications and mechanical compatibility. The GLDNA#40 is the manufacturer-recommended substitute. All parts are functionally interchangeable based on provided electrical and mechanical parameters. Selection is based on packaging preference and inventory availability.

Q: What is the Moisture Sensitivity Level (MSL) rating and why is it important?

A: The MSL 3 (168 Hours) rating indicates that substitute parts can be exposed to ambient conditions of 30°C and 85% relative humidity for up to 168 hours before soldering without requiring baking. This specification is critical for supply chain handling and assembly processes.

Q: Are there any differences in operating temperature range between the main part and substitutes?

A: No. All parts, including the Obsolete R5F100GLDNA#W0 and all substitute parts, operate across the identical temperature range of -40°C to 85°C (TA).

Q: Can substitute parts be used in existing designs without modification?

A: Yes. Complete electrical and mechanical equivalence ensures that substitute parts can be used in existing designs without circuit modification or PCB redesign. The 48-pin HWQFN (7x7) footprint and all electrical parameters remain identical.
