Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERG-2SJ393 is determined by strict equivalence across the following critical parameters:

• Resistance value: 39 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Temperature coefficient: ±350ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.157" Dia x 0.472" L (4.00mm x 12.00mm)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The ERG-2SJ393E qualifies as a direct substitute based on matching all electrical specifications and thermal characteristics. The primary distinction is the availability of radial-formed lead options in addition to standard axial configuration, which does not affect electrical performance or thermal behavior.

Parameter Comparison

Engineering Selection Recommendations

The ERG-2SJ393E is a direct electrical and thermal equivalent to the ERG-2SJ393. Both components maintain identical resistance, tolerance, power dissipation capability, and operating temperature specifications. Both are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component procurement.

The ERG-2SJ393E offers lead configuration flexibility through radial-formed options while maintaining the same physical envelope and electrical performance. Selection between standard axial and radial-formed configurations depends solely on circuit board layout requirements and mechanical assembly constraints.

Frequently Asked Questions (FAQ)

Q: Can ERG-2SJ393E be used as a direct replacement for ERG-2SJ393?

A: Yes. The ERG-2SJ393E meets all electrical and thermal specifications of the ERG-2SJ393, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both components are physically identical at 0.157" Dia x 0.472" L (4.00mm x 12.00mm).

Q: What is the difference between ERG-2SJ393 and ERG-2SJ393E?

A: The primary difference is lead configuration flexibility. The ERG-2SJ393E offers both standard axial and radial-formed lead options, while the ERG-2SJ393 is specified as axial only. Electrical performance and thermal characteristics are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both ERG-2SJ393 and ERG-2SJ393E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does lead configuration affect circuit performance?

A: No. Lead configuration (axial versus radial-formed) is a mechanical consideration for board layout and assembly. Electrical performance, resistance value, tolerance, power dissipation, and thermal behavior remain unchanged.

Q: What operating temperature range is supported?

A: Both components operate across -55°C to 235°C with a temperature coefficient of ±350ppm/°C, providing stable performance across industrial and high-temperature applications.
