Engineering Selection Recommendations

RGF1K-E3/67A is a direct parametric equivalent to RGF1KHE3_A/I and qualifies for substitution based on the following factors:

Electrical Equivalence: All critical electrical parameters match exactly, including reverse voltage rating, forward voltage drop, reverse recovery time, leakage current, and junction capacitance.
Mechanical Compatibility: Both devices use identical DO-214BA (GF1) surface mount packaging, ensuring PCB footprint and assembly process compatibility.
Thermal Performance: Operating temperature range is identical (-65°C to 175°C), supporting equivalent thermal design margins.
Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity classification (MSL 1).
Product Status: Both devices are actively manufactured by Vishay General Semiconductor - Diodes Division, ensuring long-term availability and supply chain stability.
Packaging Difference: RGF1K-E3/67A is supplied in Tape & Reel (TR) format, whereas RGF1KHE3_A/I packaging is not specified. This difference affects only procurement and handling; electrical and mechanical performance remain identical.

Frequently Asked Questions (FAQ)

Q: Can RGF1K-E3/67A be used as a direct replacement for RGF1KHE3_A/I in production?

A: Yes. RGF1K-E3/67A meets all electrical and mechanical specifications of RGF1KHE3_A/I. No circuit modifications or performance degradation will occur. The only difference is packaging format (Tape & Reel versus unspecified).

Q: Are there any thermal or reliability differences between these parts?

A: No. Both devices share identical operating temperature ranges (-65°C to 175°C), reverse recovery characteristics, and leakage specifications. Reliability performance is equivalent.

Q: Does the Tape & Reel packaging of RGF1K-E3/67A affect electrical performance?

A: No. Packaging format affects only procurement, storage, and assembly handling. Electrical and thermal performance are unaffected.

Q: Are both parts qualified to the same automotive standards?
