RL207 Equivalent & Substitute Parts

Part Overview

The RL207 is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. Manufactured by SMC Diode Solutions, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Engineering Selection Recommendations

Direct Equivalent - RL207G

The RL207G from HY Electronic (Cayman) Limited is the primary direct equivalent. It maintains the same 1000 V / 2 A rating and DO-15 package configuration. The RL207G is active in production with ROHS3 compliance and extended operating temperature range (-55°C ~ 150°C). Forward voltage is marginally higher at 1.1 V @ 2 A compared to 1 V @ 2 A for the original RL207, which remains within acceptable rectifier diode specifications. This part is suitable for direct substitution in applications where the original RL207 was specified.

Upgrade Option - 2A07G B0G

The 2A07G B0G from Taiwan Semiconductor Corporation provides equivalent electrical performance with active product status and ROHS3 compliance. It matches the 1000 V / 2 A specification and forward voltage of 1 V @ 2 A. The operating temperature range extends to -55°C ~ 150°C. Capacitance is reduced to 15pF @ 4V, 1MHz, which may benefit applications sensitive to junction capacitance. This part is suitable for new designs and production applications requiring active manufacturer support.

Similar Alternative - 1N5399GP-E3/54

The 1N5399GP-E3/54 from Vishay General Semiconductor - Diodes Division is rated for 1000 V / 1.5 A. The reduced current rating of 1.5 A compared to the 2 A specification of the RL207 limits its application to circuits where the maximum average rectified current does not exceed 1.5 A. This part is active with ROHS3 compliance and extended operating temperature range (-65°C ~ 175°C). Forward voltage is 1.4 V @ 1.5 A. Use this part only when circuit current requirements are confirmed to be 1.5 A or less.

Similar Alternative - 3A100 A0G

The 3A100 A0G from Taiwan Semiconductor Corporation is rated for 1000 V / 3 A, providing higher current capacity than the original RL207. This part is active with ROHS3 compliance and operating temperature range of -55°C ~ 150°C. Forward voltage is 1.1 V @ 3 A. The increased current rating allows use in applications requiring higher rectified current. Capacitance is 27pF @ 4V, 1MHz. This part is suitable for applications where the 2 A rating is insufficient.

Frequently Asked Questions (FAQ)

Q: Can RL207G be used as a direct replacement for RL207?

A: Yes. The RL207G maintains the same 1000 V reverse voltage, 2 A average rectified current, and DO-15 through-hole package. The forward voltage difference of 0.1 V (1.1 V vs. 1 V @ 2 A) is within standard rectifier diode tolerances and does not affect circuit functionality in typical applications.

Q: What is the difference between DO-15 and DO-204AC packaging?

A: DO-15 and DO-204AC are equivalent package designations for the same axial through-hole diode form factor. Both packages are mechanically and electrically compatible for the parts listed in this reference.

Q: Can 1N5399GP-E3/54 replace RL207 in all applications?

A: No. The 1N5399GP-E3/54 is rated for 1.5 A average rectified current, which is lower than the RL207 specification of 2 A. This part is suitable only for applications where the maximum average rectified current does not exceed 1.5 A. Exceeding this rating will cause component failure.

Q: Is 3A100 A0G a suitable upgrade for RL207?

A: Yes, for applications requiring higher current capacity. The 3A100 A0G is rated for 3 A average rectified current, exceeding the RL207 specification of 2 A. It maintains the same 1000 V reverse voltage and DO-15 package. Use this part when circuit design requires current handling above 2 A.

Q: What compliance certifications should I verify for new designs?

A: All active substitute parts listed (RL207G, 2A07G B0G, 1N5399GP-E3/54, 3A100 A0G) are ROHS3 compliant. REACH status is REACH Unaffected for all parts except RL207G, which shows Vendor Undefined status. Verify REACH compliance with the supplier for RL207G if required by your application or regulatory framework.

Q: Are there temperature range considerations when selecting a substitute?

A: Yes. The original RL207 operates from -65°C to 125°C. Most active substitutes extend this range to -55°C ~ 150°C or higher. If your application requires operation below -55°C, the 1N5399GP-E3/54 (-65°C ~ 175°C) is the only listed option that matches or exceeds the lower temperature limit of the original part.

Q: What is the significance of capacitance differences between parts?

A: Capacitance values range from 15pF to 27pF @ 4V, 1MHz across the listed parts. In most general-purpose rectifier applications, these variations have minimal impact. However, in high-frequency or sensitive analog circuits, capacitance differences may affect circuit behavior. Verify capacitance specifications against your circuit design requirements.
