UFM11PL-TP Equivalent & Substitute Parts

Part Overview

The UFM11PL-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50V DC reverse voltage and 1A average rectified current in a surface mount SOD-123FL package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for applications requiring continued supply, legacy system maintenance, or design transitions to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UFM11PL-TP are identified based on electrical parameter compatibility within the following criteria:

Electrical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 50V minimum
• Current - Average Rectified (Io): 1A minimum
• Package compatibility: SOD-123 family packages
• Mounting type: Surface Mount

Compliance Matching Parameters:

• RoHS3 Compliance required
• REACH Unaffected status
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The CGRKM4001-HF meets these substitution criteria, sharing identical voltage and current ratings, surface mount technology, and compliance certifications. Both components operate within the same thermal range and package family, enabling functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

UFM11PL-TP (Main Part): The UFM11PL-TP is classified as "Not For New Designs" and should not be selected for new circuit development. This part is suitable only for legacy system support, repair, or replacement applications where the original specification is required. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating, supporting long-term storage and handling.

CGRKM4001-HF (Substitute): The CGRKM4001-HF is an active product from Comchip Technology and is the recommended selection for new designs and ongoing production. This substitute meets all electrical requirements of the UFM11PL-TP with identical voltage and current ratings. The CGRKM4001-HF demonstrates superior reverse leakage characteristics (5 µA versus 10 µA) and maintains ROHS3 compliance and unlimited MSL rating. The forward voltage specification is marginally higher (1.1V versus 1V), which is acceptable within standard circuit tolerance margins for general-purpose rectification applications.

The minimum operating temperature of the CGRKM4001-HF is -55°C compared to -65°C for the UFM11PL-TP. This difference is non-critical for most industrial and commercial applications but should be verified for extreme low-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the CGRKM4001-HF directly replace the UFM11PL-TP in existing circuits?

A: Yes. Both components share identical voltage ratings (50V), current ratings (1A), and surface mount package family (SOD-123). The electrical parameters are compatible for general-purpose rectification applications. The forward voltage difference of 0.1V is within acceptable tolerance for most circuit designs.

Q: What is the difference between SOD-123F and SOD-123T packages?

A: Both are surface mount packages within the SOD-123 family with identical electrical performance and pin configuration. The designations reflect minor physical variations in lead geometry or tape orientation. These packages are mechanically and electrically interchangeable for standard PCB assembly processes.

Q: Why is the UFM11PL-TP marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status at the manufacturer. Micro Commercial Co no longer recommends this component for new product development. The CGRKM4001-HF, classified as "Active," is the appropriate selection for new designs requiring equivalent functionality.

Q: Are there compliance differences between the two parts?

A: No. Both the UFM11PL-TP and CGRKM4001-HF are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Compliance certifications are equivalent, supporting use in regulated industries and applications with environmental requirements.

Q: What is the significance of the reverse leakage current difference?

A: The CGRKM4001-HF exhibits lower reverse leakage (5 µA versus 10 µA at 50V). This represents improved device quality and lower power dissipation in reverse bias conditions. For most applications, this difference is negligible, but it provides a performance advantage in low-power or precision circuits.

Q: Should the operating temperature range difference be considered?

A: The CGRKM4001-HF operates from -55°C to 150°C, while the UFM11PL-TP operates from -65°C to 150°C. The 10°C difference at the lower limit is non-critical for standard industrial and commercial applications. Applications requiring operation below -55°C should retain the UFM11PL-TP or specify alternative components rated to -65°C.
