Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL105-AP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage Rating: 600V DC reverse voltage (Vr) maximum
• Current Rating: 1A average rectified current (Io)
• Forward Voltage: 1.1V maximum at 1A forward current
• Recovery Speed: Standard recovery characteristic (>500ns, >200mA)
• Reverse Leakage: 5µA at 600V
• Junction Capacitance: 15pF at 4V, 1MHz
• Package Type: Axial through-hole (A-405)
• Operating Temperature Range: -55°C to 150°C junction temperature
• Compliance: ROHS3 compliant

Parts meeting all these parameters are classified as direct substitutes. The RL105-AP is obsolete; therefore, active product alternatives with identical electrical and mechanical specifications are required for component replacement.

Parameter Comparison

Engineering Selection Recommendations

The RL105GP-AP is a direct functional equivalent to the RL105-AP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications, mechanical packaging, and compliance certifications.

Primary Recommendation: RL105GP-AP

The RL105GP-AP is the preferred substitute because it maintains active product status with Micro Commercial Co, ensuring ongoing availability and supply chain continuity. All electrical parameters, thermal characteristics, and regulatory compliance (ROHS3) are identical to the RL105-AP. The axial A-405 package provides direct mechanical compatibility with existing PCB layouts and through-hole assembly processes.

The transition from RL105-AP (obsolete) to RL105GP-AP (active) presents no functional or performance degradation. Both parts are rated for identical voltage (600V), current (1A), forward voltage drop (1.1V @ 1A), recovery speed, reverse leakage, and operating temperature range (-55°C to 150°C).

Frequently Asked Questions (FAQ)

Q: Can RL105GP-AP be used as a direct replacement for RL105-AP in existing designs?

A: Yes. The RL105GP-AP is a direct substitute with identical electrical ratings, forward voltage characteristics, reverse leakage, recovery speed, and package configuration. No circuit modifications are required.

Q: Are there any differences in thermal performance between RL105-AP and RL105GP-AP?

A: No. Both parts share the same operating temperature range (-55°C to 150°C junction temperature) and identical thermal characteristics.

Q: Does the A-405 axial package fit the same PCB footprint for both parts?

A: Yes. Both RL105-AP and RL105GP-AP use the A-405 axial through-hole package, providing identical mechanical compatibility with existing board layouts.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The RL105-AP is classified as obsolete, indicating discontinued production. The RL105GP-AP maintains active status, ensuring continued manufacturing, availability, and supply chain support. For new designs and ongoing production, the RL105GP-AP is the appropriate selection.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RL105-AP and RL105GP-AP are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage rating (600V), current rating (1A), forward voltage (1.1V @ 1A), recovery speed (Standard >500ns), reverse leakage (5µA @ 600V), and junction capacitance (15pF @ 4V, 1MHz).
