Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1CE-TP is determined by compatibility across the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: DO-214AC, SMA (surface mount form factor)
• Mounting Type: Surface Mount
• Current - Average Rectified (Io): 1 A minimum
• Technology: Standard rectifier diode
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 150 V
• Voltage - Forward (Vf) (Max) @ If: Equal to or lower than 975 mV @ 1 A
• Reverse Recovery Time (trr): Equal to or lower than 50 ns
• Operating Temperature - Junction: Equal to or wider than -50°C ~ 150°C range

The ES1D-LTP qualifies as a direct substitute based on these criteria, offering improved electrical performance characteristics while maintaining package compatibility and compliance requirements.

Engineering Selection Recommendations

The ES1D-LTP is a qualified substitute for the obsolete ES1CE-TP based on the following engineering factors:

Product Status Consideration: The ES1CE-TP is classified as obsolete, whereas the ES1D-LTP maintains active production status. This ensures long-term availability and supply chain continuity for new designs and ongoing production requirements.

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement. Both components carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Electrical Performance: The ES1D-LTP provides equal or superior electrical characteristics across all measured parameters. The substitute component operates at a higher reverse voltage rating (200 V versus 150 V), lower forward voltage drop (950 mV versus 975 mV), and faster reverse recovery time (35 ns versus 50 ns). These improvements enhance circuit reliability and efficiency without introducing compatibility issues in applications designed for the ES1CE-TP.

Thermal Operating Range: The ES1D-LTP extends the operating temperature range to -65°C ~ 175°C, compared to the main part's -50°C ~ 150°C range, providing greater flexibility for temperature-sensitive applications.

Package and Mounting Compatibility: Both components utilize identical DO-214AC (SMA) surface mount packaging, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the ES1D-LTP be used as a direct replacement for the ES1CE-TP in existing designs?

A: Yes. The ES1D-LTP is electrically and mechanically compatible with the ES1CE-TP. Both components share the same DO-214AC (SMA) surface mount package, identical current rating (1 A), and equivalent reverse leakage characteristics. The ES1D-LTP's higher voltage rating (200 V) and improved performance parameters do not create compatibility issues in circuits designed for the 150 V ES1CE-TP.

Q: What are the key differences between these two diodes?

A: The primary differences are voltage rating (ES1D-LTP rated 200 V versus ES1CE-TP at 150 V), forward voltage drop (ES1D-LTP at 950 mV versus ES1CE-TP at 975 mV), reverse recovery time (ES1D-LTP at 35 ns versus ES1CE-TP at 50 ns), and operating temperature range (ES1D-LTP extends to -65°C and 175°C). The ES1D-LTP also maintains active production status while the ES1CE-TP is obsolete.

Q: Are there any circuit design considerations when substituting the ES1D-LTP for the ES1CE-TP?

A: No design modifications are required. The ES1D-LTP's superior electrical characteristics (higher voltage rating, lower forward drop, faster recovery) are fully compatible with circuits designed for the ES1CE-TP. The substitute component will perform identically or better in the original application.

Q: What is the packaging difference between these parts?

A: Both components use DO-214AC (SMA) surface mount packaging. The ES1CE-TP is supplied in Tape & Reel (TR) format, while the ES1D-LTP is available in Cut Tape (CT) and Digi-Reel® formats. The physical package dimensions and PCB footprint are identical.

Q: Why is the ES1CE-TP listed as obsolete?

A: The ES1CE-TP is classified as obsolete by the manufacturer. The ES1D-LTP represents the active production equivalent, offering improved specifications and continued availability for new designs and production support.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the ES1CE-TP and ES1D-LTP are ROHS3 compliant and REACH unaffected. They share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, satisfying equivalent regulatory and compliance requirements.
