RL105-TP Equivalent & Substitute Parts

Part Overview

The RL105-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600V DC reverse voltage and 1A average rectified current in an axial through-hole package (A-405). This part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. The RL105-TP remains in stock inventory (861 pieces), but its obsolete status necessitates qualification of substitute parts for future procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: Axial
• Supplier Device Package: A-405

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The RL105GP-TP qualifies as a direct substitute based on identical electrical ratings, mechanical configuration, and compliance certifications. The primary distinction is product status (active versus obsolete) and packaging format (Tape & Reel versus bulk inventory).

Parameter Comparison

Engineering Selection Recommendations

The RL105GP-TP is the qualified substitute for the RL105-TP based on complete electrical and mechanical parameter equivalence. Selection of the RL105GP-TP is supported by the following factors:

Product Status: The RL105GP-TP carries active product status, ensuring continued manufacturer support, availability, and compliance with current industry standards. The RL105-TP is classified as obsolete, indicating discontinued production and limited long-term availability.

Compliance Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming equivalent environmental and regulatory qualification.

Electrical Performance: All electrical parameters—reverse voltage rating, forward voltage drop, rectified current capacity, recovery speed, reverse leakage current, and junction capacitance—are identical between the two parts.

Mechanical Configuration: Both parts utilize identical axial through-hole packaging (A-405 supplier device package), ensuring direct physical and electrical compatibility in existing circuit board layouts and assembly processes.

Packaging Consideration: The RL105GP-TP is supplied in Tape & Reel format, which is standard for active production components. The RL105-TP bulk inventory (861 pieces) may be used for immediate requirements, with transition to RL105GP-TP for future procurement.

Frequently Asked Questions (FAQ)

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

A: Yes. The RL105GP-TP is electrically and mechanically equivalent to the RL105-TP across all specified parameters. No circuit modifications or re-qualification are required for substitution.

Q: What is the difference between the RL105-TP and RL105GP-TP?

A: The parts are electrically and mechanically identical. The primary differences are product status (RL105-TP is obsolete; RL105GP-TP is active) and packaging format (RL105-TP is supplied in bulk; RL105GP-TP is supplied in Tape & Reel format).

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. No additional compliance qualification is required for substitution.

Q: Will the RL105GP-TP fit the same PCB footprint as the RL105-TP?

A: Yes. Both parts use identical axial through-hole packaging (A-405), ensuring direct physical compatibility with existing circuit board layouts and assembly processes.

Q: Why is the RL105-TP marked as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The RL105GP-TP represents the active equivalent for ongoing procurement and production use.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is used for inventory stock and manual assembly. Tape & Reel packaging is the standard format for automated assembly processes and high-volume production. Both formats contain identical components with identical electrical and mechanical specifications.

Q: Can I mix RL105-TP and RL105GP-TP components in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent and carry identical compliance certifications. They can be used interchangeably in the same circuit design and assembly process.

Q: What is the operating temperature range for these diodes?

A: Both the RL105-TP and RL105GP-TP operate across a junction temperature range of -55°C to 150°C, suitable for industrial and commercial applications.

Q: Are these parts suitable for high-frequency applications?

A: These are standard recovery rectifier diodes with recovery time greater than 500 nanoseconds at currents exceeding 200 milliamps. They are classified as standard-speed diodes and are suitable for low-to-moderate frequency rectification applications, not high-frequency switching applications.
