SR805-AP Equivalent & Substitute Parts Engineering Reference

Part Overview

The SR805-AP, manufactured by Micro Commercial Co, is a Schottky diode rated at 50 V and 8A, housed in a through-hole DO-201AD (Axial) package. As this model is marked "Not For New Designs," sourcing equivalent or substitute components is necessary for new product development and continued production where SR805-AP inventory is limited or product longevity dictates. Identifying substitutes ensures consistent supply and compliance with ongoing design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based on matching all critical electrical and mechanical parameters: Schottky technology, reverse voltage rating, average rectified current rating, forward voltage at specified current, reverse leakage current, recovery speed, package/case compatibility, and mounting type. Only parts with these parameters explicitly listed and matching the required specifications are considered valid substitutes within the category of diodes, rectifiers.

Parameter Comparison

Engineering Selection Recommendations

SR805-AP is classified as "Not For New Designs," indicating limited future availability for new project designs. In contrast, SR505 A0G is listed as "Active" and is ROHS3 compliant and REACH unaffected. When compliance and availability are required for new designs, selection should align with components that have active product status and relevant environmental certifications.

Frequently Asked Questions (FAQ)

Q1: Which parameters must be matched when substituting the SR805-AP?
A1: All replacements must match Schottky technology, reverse voltage rating, average rectified current rating, forward voltage at specified current, speed, reverse leakage current, package/case, supplier device package, and mounting type.

Q2: Can a DO-201AD (Axial) package be directly replaced with another package type?
A2: Only parts with the same mechanical package/case (DO-201AD, Axial) and supplier device package should be considered directly compatible replacements.

Q3: Is the average rectified current (Io) different between SR805-AP and SR505 A0G?
A3: Yes, SR805-AP is rated at 8A while SR505 A0G is rated at 5A. This should be considered when the circuit requires a minimum current capability.

Q4: Are there compliance considerations for new designs?
A4: For new designs, use components with "Active" product status and environmental compliance information, such as ROHS3 compliance and REACH unaffected status.

Q5: Is it necessary to match the operating temperature range for substitutes?
A5: Substitutes should meet or exceed the required operating temperature range specified for the intended application. The only provided data should be compared directly.
