Engineering Selection Recommendations

The 1F5 from SMC Diode Solutions is the direct equivalent substitute for the obsolete 1F5G-TP. Both components are ROHS3 compliant and carry identical electrical ratings for reverse voltage, forward voltage, and reverse recovery time. The 1F5 offers an extended lower operating temperature limit (-65°C versus -55°C), providing additional thermal margin in low-temperature applications.

The 1F5 is currently in active production status, ensuring availability for new designs and replacement inventory. Both components share identical package specifications (R-1 axial through-hole), mechanical compatibility, and regulatory classifications (EAR99, HTSUS 8541.10.0080).

Selection of the 1F5 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs utilizing the 1F5G-TP.

Frequently Asked Questions (FAQ)

Q: Can the 1F5 directly replace the 1F5G-TP in existing designs?

A: Yes. The 1F5 is electrically and mechanically equivalent to the 1F5G-TP. Both components have identical voltage ratings (600 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), and reverse recovery time (250 ns). The R-1 axial through-hole package is identical, allowing direct board-level substitution without design modification.

Q: What is the primary reason for substituting the 1F5G-TP?

A: The 1F5G-TP is classified as obsolete. The 1F5 is an active product in current production, ensuring long-term supply chain availability and eliminating the risk of component discontinuation.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant and carry the same export classification (EAR99) and tariff code (HTSUS 8541.10.0080). The 1F5 is REACH Affected, while the 1F5G-TP is REACH Unaffected; however, both meet applicable regulatory requirements for their respective manufacturing jurisdictions.

Q: Does the 1F5 have any performance advantages over the 1F5G-TP?

A: The 1F5 extends the lower operating temperature limit to -65°C compared to -55°C for the 1F5G-TP, providing additional thermal operating margin in cold-temperature environments. All other electrical parameters are identical.

Q: Is the packaging identical between the two parts?

A: Yes. Both the 1F5G-TP and 1F5 use the R-1 axial through-hole package. The 1F5G-TP is supplied in standard packaging, while the 1F5 is supplied in Tape & Box (TB) format. Both are suitable for through-hole PCB assembly without modification.

Q: What is the capacitance difference noted in the parameter comparison?

A: The 1F5 has a capacitance of 15 pF @ 4 V, 1 MHz, compared to 12 pF for the 1F5G-TP. This minor difference does not affect substitution suitability for general-purpose rectification applications.
