Frequently Asked Questions (FAQ)

Q: Can ES1B-13-F directly replace ES1B-TP in existing designs?

A: Yes. Both parts meet the core electrical requirements: 100 V reverse voltage, 1 A average rectified current, fast recovery speed, and 5 µA reverse leakage. Both use DO-214AC (SMA) surface mount packages. The ES1B-13-F has lower forward voltage (920 mV vs. 975 mV) and faster reverse recovery time (25 ns vs. 50 ns), which are improvements for circuit performance.

Q: What is the difference between DO-214AC and DO-214BA packages?

A: Both packages are surface mount diode packages compatible with SMA footprints. DO-214AC and DO-214BA differ in physical dimensions and lead configuration but are electrically equivalent for this application. Parts using DO-214BA (such as EGF1B-E3/5CA) are suitable substitutes if the PCB footprint accommodates the package variant.

Q: Why do some substitute parts have different forward voltage specifications?

A: Forward voltage variation (900 mV to 1.1 V @ 1 A) is within normal manufacturing tolerance for general-purpose rectifier diodes. The ES1B-TP specification of 975 mV @ 1 A is the maximum rating. All listed substitutes meet or exceed this specification. Lower forward voltage in substitutes (such as 900 mV) indicates improved efficiency and reduced power dissipation.

Q: Are automotive-qualified parts (ESH1BHE3_A/H, ESH1BHE3_A/I) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts with AEC-Q101 certification meet or exceed the electrical and reliability requirements for general-purpose applications. These parts are fully compatible with standard industrial designs and offer additional qualification assurance.

Q: What is the significance of the extended temperature range in substitute parts?

A: The ES1B-TP operates from -50°C to 150°C. Many substitutes extend this range to -55°C to 175°C or -65°C to 175°C. Extended temperature range provides design margin for applications operating at temperature extremes and is not a limitation for designs within the original temperature specification.

Q: Can I use EGF1B-E3/5CA (DO-214BA package) if my PCB is designed for DO-214AC?

A: DO-214BA and DO-214AC packages have different physical dimensions. PCB footprint compatibility must be verified before substitution. If the PCB footprint is specifically designed for DO-214AC (HSMA or SMA variant), use only DO-214AC package substitutes such as ES1B-13-F, ESH1B-E3/5AT, or ESH1B-E3/61T.

Q: What is the inventory status for substitute parts?

A: Current inventory levels are: ES1B-13-F (35,100 pcs), EGF1B-E3/67A (30,200 pcs), ES1B (YAGEO, 65,100 pcs), EGF1B-E3/5CA (15,300 pcs), ES1B-LTP (17,200 pcs), ESH1B-E3/61T (10,100 pcs), ESH1B-E3/5AT (833 pcs), ESH1BHE3_A/I (965 pcs), ESH1BHE3_A/H (720 pcs), CGRA4002-G (957 pcs). Inventory levels are subject to change; verify current availability with suppliers.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, matching the regulatory compliance of the original ES1B-TP.
