Key Parameters

Substitute Part Grouping Explanation

Substitute candidates for RL 10Z are chosen by matching the key electrical and mechanical parameters. Allowed parameters for substitution include voltage rating (Vr), current rating (Io), voltage drop (Vf), fast recovery speed (trr), reverse leakage current, mounting type, package/case configuration, operating temperature range, and compliance certifications. Only parts with strictly equivalent or compliant values for these parameters are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

Due to the obsolete product status of the RL 10Z diode, engineering selection must consider available alternatives with compatible electrical and mechanical specifications. HER203G A0G from Taiwan Semiconductor Corporation is a suitable substitute, matching allowable voltage, current, speed, and compliance parameters. Both parts maintain MSL 1 (Unlimited), RoHS compliance, and the same export classification. Selection for replacement is strictly validated by status and certifications as provided.

Frequently Asked Questions (FAQ)

Q1: What determines if HER203G A0G is a direct substitute for RL 10Z?
A1: Equivalent voltage rating, current rating, reverse recovery time, speed, mounting type, operating temperature range, and compliance certifications.

Q2: Is the package form of HER203G A0G compatible with RL 10Z?
A2: Both parts utilize axial through-hole mounting. HER203G A0G specifies DO-204AC (DO-15) which is an axial configuration.

Q3: Are there compliance concerns when substituting HER203G A0G for RL 10Z?
A3: Both diodes are RoHS compliant and have the same MSL level and ECCN/HTSUS classification, meeting compliance requirements.

Q4: Are performance parameters such as recovery time and leakage current within acceptable limits for substitution?
A4: Reverse recovery time matches exactly; reverse leakage current is stricter (lower) in HER203G A0G, which is acceptable based on the provided parameters.

Q5: Does operating temperature range differ significantly between the parts?
A5: HER203G A0G supports a wider low-temperature range, remaining within the upper specification required by RL 10Z.

Q6: Can HER203G A0G be used in all applications where RL 10Z was previously specified?
A6: Compatibility for substitution is validated strictly by matching provided electrical, mechanical, and compliance parameters. No other application-specific data is included.
