Substitute Part Grouping Explanation

Substitution of the RGL34D/1 is determined by electrical and mechanical parameter equivalence within the SUPERECTIFIER® series. The following criteria establish valid substitutes:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 500 mA
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 500 mA
Reverse Recovery Time (trr): 150 ns
Current - Reverse Leakage @ Vr: 5 µA @ 200 V
Capacitance @ Vr, F: 4 pF @ 4V, 1MHz
Package / Case: DO-213AA (Glass)
Mounting Type: Surface Mount
Operating Temperature - Junction: -65°C to 175°C

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility with the original RGL34D/1 specification. Substitutes differ in product status (active versus obsolete) and packaging configuration (bulk versus tape & reel).

Engineering Selection Recommendations

All three substitute parts (RGL34D-E3/83, RGL34D-E3/98, and RGL34DHE3/98) provide complete electrical and mechanical equivalence to the RGL34D/1. Selection among these alternatives is based on product status and regulatory compliance:

RGL34D-E3/83 and RGL34D-E3/98 are active products with ROHS3 compliance certification, addressing the regulatory non-compliance status of the original RGL34D/1. Both parts are available in tape & reel packaging, suitable for automated assembly processes.

RGL34DHE3/98 is an active product with ROHS3 compliance and represents the highest inventory availability among all substitutes. This part carries the same electrical and thermal specifications as the original component.

For new designs or production requiring regulatory compliance with modern environmental standards, any of the three active substitutes are appropriate selections. For legacy system maintenance where original packaging configuration is not a constraint, RGL34DHE3/98 offers the most robust supply position.

Frequently Asked Questions (FAQ)

Q: Can RGL34D-E3/83, RGL34D-E3/98, and RGL34DHE3/98 be used interchangeably with RGL34D/1?

A: Yes. All three substitute parts maintain identical electrical performance parameters, reverse recovery characteristics, and thermal operating ranges. The DO-213AA package geometry is consistent across all variants, ensuring mechanical compatibility in surface mount applications.

Q: What is the difference between RGL34D-E3/98 and RGL34DHE3/98?

A: Both parts are electrically and thermally equivalent. The primary difference is packaging configuration: RGL34D-E3/98 is supplied in tape & reel format, while RGL34DHE3/98 packaging is not specified. RGL34DHE3/98 offers significantly higher inventory availability.

Q: Why is the RGL34D/1 marked as obsolete?

A: The RGL34D/1 carries an obsolete product status designation. The active substitute parts (RGL34D-E3/83, RGL34D-E3/98, and RGL34DHE3/98) provide continued access to equivalent fast recovery rectifier diode functionality within the SUPERECTIFIER® series.

Q: Are the substitute parts RoHS compliant?

A: Yes. RGL34D-E3/83, RGL34D-E3/98, and RGL34DHE3/98 all carry ROHS3 compliance certification. The original RGL34D/1 is RoHS non-compliant. Substitution with any of these active parts addresses regulatory compliance requirements.

Q: Does the DO-213AA package remain the same across all parts?

A: Yes. All parts, including the original RGL34D/1 and all three substitutes, utilize the DO-213AA (Glass) package configuration. Surface mount footprint and mechanical dimensions are identical, enabling direct board-level substitution without layout modifications.

Q: What is the reverse recovery time specification, and why is it important?

A: The reverse recovery time (trr) is 150 ns for all parts in this equivalence group. This parameter defines the diode's switching speed and is critical for high-frequency rectification applications. Identical trr values ensure equivalent performance in switching power supplies and similar circuits.
