Substitute Part Grouping Explanation

The ER38 is identified as a direct substitute for the ES38 based on the following substitution criteria:

Common Classification Parameters:

• Manufacturer: SMC Diode Solutions (same manufacturer)
• Category: Diodes, Rectifiers (identical functional category)
• Description: MODULAR (matching form factor designation)
• Detailed Description: Diode (same component type)
• Base Product Number: ER3 (related product family within ES3/ER3 series)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (equivalent handling requirements)

Substitution Logic: The ER38 maintains functional equivalence through identical categorical classification, matching modular architecture, and equivalent moisture sensitivity specifications. The transition from ES3 base product family to ER3 base product family, combined with consistent MSL ratings, establishes substitution viability. The ER38 is currently in Active product status, providing ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ES38 is obsolete and no longer supported by the manufacturer. The ER38 is the designated active equivalent, currently maintained in production by SMC Diode Solutions with confirmed inventory availability (1012 Pcs New Original In Stock).

Compliance Status: The ER38 is RoHS3 Compliant, providing enhanced environmental and regulatory alignment compared to the ES38. The ER38 carries REACH Affected status, indicating full regulatory documentation and compliance tracking. The ES38 is REACH Unaffected, reflecting its obsolete classification.

Packaging Specification: The ER38 is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. This packaging specification should be evaluated against existing procurement and assembly workflows.

Selection Basis: Direct substitution of ER38 for ES38 is supported by identical functional classification, matching modular architecture, equivalent moisture sensitivity specifications, and active product status with manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the ER38 directly replace the ES38 in existing designs?

A: Yes. The ER38 maintains identical categorical classification (Diodes, Rectifiers), matching modular description, and equivalent Moisture Sensitivity Level (MSL 1 - Unlimited). Both components are manufactured by SMC Diode Solutions and share the same functional diode designation.

Q: What is the primary reason for substitution?

A: The ES38 is designated as obsolete and no longer manufactured. The ER38 is the active equivalent product, currently in production with confirmed inventory availability.

Q: Are there compliance differences between ES38 and ER38?

A: Yes. The ER38 is RoHS3 Compliant and carries REACH Affected status, indicating full regulatory documentation. The ES38 is REACH Unaffected due to its obsolete classification. The ER38 provides enhanced regulatory alignment for new designs and procurement.

Q: What packaging format is the ER38 supplied in?

A: The ER38 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly and high-volume production environments.

Q: Are there any unspecified parameters that should be evaluated?

A: Current - Average Rectified (Io), Speed, Capacitance @ Vr, Mounting Type, Package / Case, Supplier Device Package, and Operating Temperature - Junction are not specified in the available technical data for either component. These parameters should be obtained from the manufacturer's detailed datasheets prior to final design implementation.

Q: What is the inventory status of the ER38?

A: The ER38 has 1012 Pcs New Original In Stock, confirming active availability through SMC Diode Solutions distribution channels.
