Substitute Part Grouping Explanation

Substitution of the HT11G R0G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: T-18, Axial
• Supplier Device Package: TS-1

Compliance Criteria:

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

A substitute part must match all electrical parameters, mechanical specifications, and compliance certifications to ensure direct interchangeability without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The HT11G (without the R0G suffix designation) serves as the direct equivalent substitute for the HT11G R0G. Both components are manufactured by Taiwan Semiconductor Corporation and exhibit identical electrical characteristics, mechanical specifications, and compliance certifications across all measured parameters.

The primary distinction between the two part numbers is product status: the HT11G R0G is discontinued at DiGi Electronics, while the HT11G maintains active status with current inventory availability. This status difference, combined with identical parameter specifications, establishes the HT11G as the appropriate replacement for ongoing procurement and design continuity.

Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Current inventory levels support immediate component availability for both the original specification and the substitute, enabling seamless transition in production environments.

Frequently Asked Questions (FAQ)

Q: What is the difference between HT11G R0G and HT11G?

A: The HT11G R0G and HT11G are electrically and mechanically identical components from Taiwan Semiconductor Corporation. The primary difference is product status: HT11G R0G is discontinued at DiGi Electronics, while HT11G maintains active status. All electrical parameters, mechanical specifications, and compliance certifications are identical.

Q: Can HT11G be used as a direct replacement for HT11G R0G in existing designs?

A: Yes. The HT11G is a direct substitute for HT11G R0G. No circuit modifications, PCB layout changes, or performance adjustments are required. Both components share identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (1 V @ 1 A), recovery time (50 ns), and package specifications (T-18, Axial, TS-1).

Q: Are there any compliance or certification differences between the two parts?

A: No. Both HT11G R0G and HT11G carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). No additional qualification or testing is required when transitioning between these parts.

Q: What are the critical parameters that define substitution eligibility for this diode?

A: Substitution eligibility is determined by matching the following parameters: Voltage - DC Reverse (50 V), Current - Average Rectified (1 A), Voltage - Forward (1 V @ 1 A), Reverse Recovery Time (50 ns), Current - Reverse Leakage (5 µA @ 50 V), Capacitance (15 pF @ 4V, 1MHz), Mounting Type (Through Hole), Package (T-18, Axial), and Supplier Device Package (TS-1). All compliance certifications must also match.

Q: Is the TS-1 package compatible with standard through-hole PCB designs?

A: Yes. The TS-1 package is a standard through-hole axial package (T-18 case style) compatible with conventional PCB drilling and wave soldering processes. No special handling or assembly modifications are required.

Q: What is the operating temperature range for this diode?

A: The operating temperature range for both HT11G R0G and HT11G is -55°C to 150°C at the junction. This range supports applications across industrial, commercial, and consumer temperature environments.

Q: Are both parts currently available for procurement?

A: Yes. Both HT11G R0G (720 Pcs) and HT11G (733 Pcs) are listed as new original in stock. However, HT11G R0G is discontinued at DiGi Electronics, making HT11G the recommended choice for ongoing procurement to ensure long-term supply continuity.
