RS3000-AP Equivalent & Substitute Parts

Part Overview

The RS3000-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 3000 V DC reverse voltage with 200 mA average rectified current in a DO-41 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating modern packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3000-AP is determined by the following critical electrical and mechanical parameters:

Voltage Compatibility: The substitute part must maintain a DC reverse voltage rating of 3000 V or greater to ensure safe operation in the same circuit topology.

Current Rating: The substitute part must support an average rectified current of 200 mA or greater. Parts with higher current ratings (such as 250 mA) are acceptable as they provide additional design margin without compromising circuit function.

Package Compatibility: Both the main part and substitute must use through-hole mounting in DO-41 or DO-204AL (equivalent designations for the same physical package) to ensure mechanical fit on existing printed circuit boards.

Thermal Range: The substitute part must operate within the required junction temperature range. Extended temperature ranges are acceptable.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and equivalent environmental certifications.

The GI250-3-E3/54 meets all substitution criteria through equivalent voltage and package specifications, with enhanced current capacity and active product status.

Engineering Selection Recommendations

The GI250-3-E3/54 is the qualified substitute for the obsolete RS3000-AP based on the following engineering criteria:

Electrical Equivalence: Both parts share identical 3000 V reverse voltage ratings and equivalent reverse leakage characteristics (5 µA @ 3000 V). The GI250-3-E3/54 provides 250 mA current capacity, exceeding the 200 mA requirement of the original part, thereby offering improved design margin without circuit modification.

Package Compatibility: Both components utilize the DO-41 through-hole axial package, ensuring direct mechanical and electrical compatibility on existing printed circuit board layouts.

Product Status and Availability: The GI250-3-E3/54 maintains active product status with 17,110 units in stock, providing reliable long-term procurement compared to the obsolete RS3000-AP with limited remaining inventory.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), ensuring equivalent environmental and handling requirements.

Thermal Performance: The GI250-3-E3/54 extends the operating temperature range to -65°C to 175°C, providing enhanced thermal margin over the original -55°C to 150°C specification.

Frequently Asked Questions (FAQ)

Q: Can the GI250-3-E3/54 directly replace the RS3000-AP without circuit modification?

A: Yes. Both parts share identical 3000 V reverse voltage ratings, equivalent reverse leakage characteristics, and identical DO-41 through-hole package geometry. The higher current rating (250 mA vs. 200 mA) does not require circuit changes and provides additional design margin.

Q: What is the significance of the higher current rating in the GI250-3-E3/54?

A: The GI250-3-E3/54 is rated for 250 mA average rectified current compared to the RS3000-AP's 200 mA rating. This higher rating indicates the part can safely conduct greater current without exceeding thermal or electrical limits. In applications requiring only 200 mA, this provides operational margin and improved reliability.

Q: Are the DO-41 and DO-204AL package designations equivalent?

A: Yes. DO-204AL and DO-41 refer to the same physical through-hole axial package. Both designations describe an identical component outline, lead diameter, and mounting footprint. Parts specified with either designation are mechanically and electrically interchangeable.

Q: What is the impact of the extended temperature range in the GI250-3-E3/54?

A: The GI250-3-E3/54 operates from -65°C to 175°C compared to the RS3000-AP's -55°C to 150°C range. This extended range accommodates applications with more demanding thermal environments. If the original application operates within -55°C to 150°C, the substitute part remains fully compatible.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the RS3000-AP and GI250-3-E3/54 are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity). They meet equivalent environmental and handling requirements for industrial and commercial applications.

Q: What is the difference in forward voltage characteristics between these parts?

A: The RS3000-AP specifies 4 V maximum forward voltage at 500 mA, while the GI250-3-E3/54 specifies 3.5 V maximum at 250 mA. These measurements are taken at different current levels and represent typical performance characteristics. Both values are within acceptable ranges for general-purpose rectifier applications.
