Engineering Selection Recommendations

For applications requiring replacement of the obsolete DF005S/27, the following selection criteria apply:

Primary Recommendation - Vishay Variants (Active Status): DF005S-E3/45, DF005S-E3/77, and DF005SA-E3/77 are direct electrical equivalents from the original manufacturer with active product status. These parts maintain identical electrical specifications and are available in higher quantities. Selection between these variants depends on packaging requirements: Tube for DF005S-E3/45, or Tape & Reel for DF005S-E3/77 and DF005SA-E3/77.

Alternative - Diodes Incorporated (Active Status, Extended Temperature Range): DF005S-T from Diodes Incorporated is an active product with identical 1 A current rating and forward voltage specification. This part offers an extended lower operating temperature limit (-65°C vs. -55°C), making it suitable for applications requiring wider temperature performance. Reverse leakage current is specified at 10 µA, which remains within acceptable limits for most applications.

Higher Current Capacity Options: DF005S from onsemi and DF15005S-G from Comchip Technology both provide 1.5 A average rectified current, offering design margin for applications approaching the 1 A limit. DF005S carries "Not For New Designs" status, while DF15005S-G maintains active status.

Parametric Equivalents - Alternative Manufacturers: ABS05-HF (Comchip Technology), DB101S (SMC Diode Solutions), and DBLS101G RDG (Taiwan Semiconductor Corporation) are parametrically equivalent with identical 50 V / 1 A specifications. DBLS101G RDG features lower reverse leakage current (2 µA), providing enhanced performance in low-leakage applications.

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can DF005S-E3/77 directly replace DF005S/27 in existing designs? A: Yes. DF005S-E3/77 is a parametric equivalent with identical electrical specifications (50 V, 1 A, 1.1 V forward voltage, 5 µA reverse leakage). The difference is packaging: DF005S/27 uses standard surface mount packaging, while DF005S-E3/77 is supplied in Tape & Reel format. Both use the same 4-SMD, Gull Wing package footprint.

Q: What is the difference between DF005S-E3/45 and DF005S-E3/77? A: Both are Vishay equivalents with identical electrical specifications. The difference is packaging format: DF005S-E3/45 is supplied in Tube packaging, while DF005S-E3/77 is supplied in Tape & Reel (TR). Electrical performance and PCB footprint are identical.

Q: Is DF005S-T from Diodes Incorporated a suitable replacement? A: Yes, with one consideration. DF005S-T meets all electrical requirements (50 V, 1 A, 1.1 V forward voltage) and offers extended lower temperature operation (-65°C vs. -55°C). Reverse leakage is specified at 10 µA, which is higher than the original 5 µA but remains acceptable for standard rectification applications.

Q: Can I use DF15005S-G or DF005S (onsemi) for higher current applications? A: Yes. Both parts provide 1.5 A average rectified current while maintaining 50 V voltage rating and 1.1 V forward voltage specification. DF15005S-G is active status; DF005S (onsemi) is "Not For New Designs" status. Use DF15005S-G for new designs requiring higher current capacity.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Q: What is the significance of reverse leakage current differences? A: Reverse leakage current (specified at 50 V) indicates the small current flowing through the diode in reverse bias. The original DF005S/27 specifies 5 µA. Substitutes with equal or lower leakage (DBLS101G RDG at 2 µA, or others at 5 µA) are directly compatible. DF005S-T at 10 µA remains acceptable for most applications but may require evaluation in high-impedance or precision circuits.

Q: Can I mix different substitute parts in the same production run? A: All listed substitutes are electrically equivalent within the specified parameters and use identical 4-SMD, Gull Wing package footprints. However, verify with your quality and procurement procedures regarding part number consistency in production documentation and traceability requirements.
