Engineering Selection Recommendations

The ES3C (base part number) is the direct substitute for the discontinued ES3C V7G. This substitution is supported by complete electrical and mechanical parameter equivalence across all specified ratings and characteristics.

Product Status Consideration: The ES3C maintains active product status with 10,200 pieces in stock inventory, compared to the discontinued ES3C V7G with 939 pieces available. This availability differential supports transition to the substitute part for new procurement and long-term design continuity.

Compliance Alignment: Both parts maintain identical ROHS3 compliance certification, REACH unaffected status, and moisture sensitivity classification (MSL 1 - Unlimited). No compliance-related design modifications are required for substitution.

Thermal and Environmental Performance: Operating temperature range, reverse leakage characteristics, and capacitance specifications remain unchanged, ensuring equivalent thermal behavior and circuit performance in target applications.

Frequently Asked Questions (FAQ)

Q: Can the ES3C be used as a direct replacement for the ES3C V7G in existing designs?

A: Yes. The ES3C provides complete electrical and mechanical equivalence to the ES3C V7G across all specified parameters, including voltage rating (150 V), current rating (3 A), reverse recovery time (35 ns), and DO-214AB package configuration. No circuit modifications are required.

Q: What is the significance of the V7G designation in the part number?

A: The V7G designation represents a specific version or manufacturing variant of the ES3C base product. The ES3C substitute part maintains identical functional specifications without the version suffix, indicating it is the current production equivalent.

Q: Are there any differences in thermal performance between the ES3C V7G and ES3C?

A: No. Both parts specify identical operating junction temperature range (-55°C to 150°C) and reverse leakage current (10 µA @ 150 V), indicating equivalent thermal characteristics and performance stability across the specified operating envelope.

Q: Does the DO-214AB package remain the same for both parts?

A: Yes. Both the ES3C V7G and ES3C utilize the DO-214AB (SMC) surface mount package. PCB layout, footprint, and assembly processes remain unchanged during substitution.

Q: Are compliance certifications maintained with the ES3C substitute?

A: Yes. The ES3C maintains identical ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity classification as the ES3C V7G. No compliance-related design review is required for substitution.

Q: What is the primary advantage of transitioning to the ES3C from the discontinued ES3C V7G?

A: The ES3C offers active product status with significantly higher inventory availability (10,200 pieces versus 939 pieces), ensuring reliable long-term procurement and supply chain continuity for ongoing production requirements.
