Substitute Part Grouping Explanation

Substitution of the STPS1L60AFN is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 570 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 60 V
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Base Product Number: STPS1

Compliance Equivalence Criteria:

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

The STPS1L60A qualifies as a direct substitute based on identical electrical ratings and compliance certifications. Package configuration differences (SMAflat Notch versus SMA DO-214AC) represent the primary distinction between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

The STPS1L60A is the active equivalent substitute for the obsolete STPS1L60AFN. Both components share identical electrical specifications across all critical rectification parameters: 60 V reverse voltage rating, 1 A average rectified current, 570 mV forward voltage drop at 1 A, and fast recovery characteristics.

Compliance Status: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with current manufacturing and environmental standards.

Product Status Consideration: The STPS1L60A carries active product status with 9400 units in stock, whereas the STPS1L60AFN is obsolete. Selection of the active substitute ensures long-term supply chain continuity and access to manufacturer technical support.

Package Configuration: The primary distinction between these parts is the package format. The STPS1L60AFN uses DO-221AC (SMAflat Notch) leads, while the STPS1L60A uses DO-214AC (SMA) leads. Both are surface mount configurations with compatible footprint geometries for standard PCB assembly processes.

Operating Temperature: The STPS1L60AFN specifies a junction temperature of 175°C, while the STPS1L60A specifies 150°C maximum. Applications operating within the 150°C junction temperature envelope experience no thermal derating relative to the original part.

Frequently Asked Questions (FAQ)

Q: Can the STPS1L60A directly replace the STPS1L60AFN in existing circuit designs?

A: Yes. The STPS1L60A provides electrical equivalence across all rectification parameters. PCB footprint compatibility depends on the specific land pattern used for the original SMAflat Notch package. Standard SMA (DO-214AC) footprints accommodate the substitute part without circuit modification.

Q: What is the difference between the SMAflat Notch and SMA package formats?

A: Both are surface mount Schottky diode packages with identical electrical performance. SMAflat Notch (DO-221AC) and SMA (DO-214AC) differ in physical lead geometry and PCB land pattern dimensions. Component placement and reflow soldering processes remain compatible with standard surface mount assembly equipment.

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

A: No. Both the STPS1L60AFN and STPS1L60A maintain identical RoHS3 compliance status and MSL Level 1 moisture sensitivity classification. REACH and ECCN designations are equivalent across both parts.

Q: Why is the operating temperature specification different between the two parts?

A: The STPS1L60AFN specifies 175°C junction temperature, while the STPS1L60A specifies 150°C maximum. This difference reflects manufacturing process variations between the obsolete and active product lines. Applications designed within the 150°C thermal envelope experience no performance degradation with the substitute part.

Q: Is the STPS1L60A available in the same packaging options as the STPS1L60AFN?

A: The STPS1L60A is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. The original STPS1L60AFN packaging format is not specified in the available data. Standard tape and reel configurations support automated PCB assembly processes.

Q: What is the inventory status of the STPS1L60A?

A: The STPS1L60A maintains active product status with 9400 units in stock, ensuring immediate availability for production and repair applications. The STPS1L60AFN is obsolete with 724 units remaining in inventory.
