Substitute Part Grouping Explanation

Substitute parts for the ACDBA1100-HF are qualified based on the following criteria:

Electrical Parameter Matching:

• Voltage - DC Reverse (Vr) (Max): 100V
• Current - Average Rectified (Io): 1A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 1A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C

Package Compatibility:

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements, ensuring functional interchangeability in circuit applications. Variations in reverse leakage current and capacitance are noted but do not preclude substitution within the specified parameter ranges.

Engineering Selection Recommendations

Primary Substitutes (Automotive-Grade with AEC-Q101):

SS110HE3-LTP (Micro Commercial Co) is the preferred substitute when automotive qualification and AEC-Q101 certification are required. This part matches the ACDBA1100-HF in grade classification and provides superior reverse leakage characteristics (50 µA @ 100V versus 200 µA @ 100V), making it suitable for applications with stringent leakage requirements.

Secondary Substitutes (General Industrial Applications):

SS110-LTP (Micro Commercial Co) and S100W_R1_00001 (Panjit International Inc.) are suitable substitutes for non-automotive applications. Both parts meet core electrical specifications and package requirements. SS110-LTP offers capacitance data matching the main part (30 pF @ 4V, 1MHz). S100W_R1_00001 provides an alternative from a different manufacturer with equivalent electrical performance.

Selection Criteria:

• For automotive applications requiring AEC-Q101 compliance: Select SS110HE3-LTP
• For general industrial applications with standard performance requirements: Select SS110-LTP or S100W_R1_00001
• All substitutes maintain ROHS3 compliance and MSL 1 rating
• All substitutes are Active product status with confirmed inventory availability

Frequently Asked Questions (FAQ)

Q: Can SS110-LTP be used as a direct replacement for ACDBA1100-HF in automotive applications?

A: SS110-LTP meets all core electrical and package specifications. However, it lacks AEC-Q101 qualification. For automotive applications requiring AEC-Q101 certification, SS110HE3-LTP is the appropriate substitute.

Q: What is the significance of the reverse leakage current difference between ACDBA1100-HF (200 µA) and SS110HE3-LTP (50 µA)?

A: Both values fall within acceptable ranges for Schottky diode operation. SS110HE3-LTP exhibits lower reverse leakage, which may provide performance advantages in applications sensitive to leakage current. The ACDBA1100-HF specification of 200 µA is within normal operating parameters for this device class.

Q: Are all substitute parts available in the same packaging options as ACDBA1100-HF?

A: All substitute parts use DO-214AC (SMA) surface mount package. Packaging format differences exist: ACDBA1100-HF is available in Cut Tape (CT) & Digi-Reel®, while substitutes are supplied in Tape & Reel (TR). Verify packaging format compatibility with your procurement and assembly requirements.

Q: Does the capacitance specification difference affect substitution suitability?

A: Capacitance values (30 pF to 35 pF range) are within typical Schottky diode specifications. S100W_R1_00001 does not specify capacitance; this does not preclude its use as a substitute. Verify capacitance requirements for your specific circuit application if this parameter is critical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (S100W_R1_00001, SS110-LTP, SS110HE3-LTP) are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the environmental compliance profile of ACDBA1100-HF.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: S100W_R1_00001 (1400 pcs), SS110-LTP (20300 pcs), SS110HE3-LTP (11109 pcs). All parts are listed as New Original In Stock.
