RL256-TP Equivalent & Substitute Parts

Part Overview

The RL256-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 2.5 A average rectified current in an R-3 axial through-hole package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and procurement continuity. The RL256-TP operates across a junction temperature range of -55°C to 150°C and complies with ROHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL256-TP is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 2.5 A
• Recovery Speed: Standard Recovery >500ns, > 200mA (Io)
• Operating Temperature Range: -55°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: R-3, Axial

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The RL256GP-TP meets all substitution criteria. Minor variations in forward voltage (1.1 V versus 1 V at 2.5 A) and junction capacitance (40 pF versus 35 pF at 4 V, 1 MHz) remain within acceptable tolerance for general-purpose rectification applications. The primary distinction is packaging format: RL256-TP is supplied in bulk, while RL256GP-TP is supplied in Tape & Reel format. The RL256GP-TP carries Active product status, providing superior long-term availability compared to the obsolete RL256-TP.

Parameter Comparison

Engineering Selection Recommendations

RL256GP-TP is the direct substitute for RL256-TP applications. Selection of RL256GP-TP is supported by the following factors:

Product Status: RL256GP-TP carries Active product status, ensuring continued manufacturing and supply availability. The RL256-TP is classified as Obsolete, creating procurement risk and potential supply discontinuation.

Electrical Compatibility: Both parts share identical voltage ratings (800 V DC reverse), current ratings (2.5 A average rectified), recovery speed characteristics, and reverse leakage specifications. Forward voltage variation (0.1 V differential at 2.5 A) and capacitance variation (5 pF differential at 4 V, 1 MHz) are within standard engineering tolerance for rectifier diode applications.

Mechanical Compatibility: Both parts utilize identical R-3 axial through-hole packaging, enabling direct board-level substitution without layout modification.

Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Packaging Consideration: RL256GP-TP is supplied in Tape & Reel format, which is standard for automated assembly processes. If bulk packaging is required, consult with the manufacturer regarding alternative packaging options for RL256GP-TP.

Frequently Asked Questions (FAQ)

Q: Can RL256GP-TP directly replace RL256-TP in existing designs?

A: Yes. RL256GP-TP is electrically and mechanically equivalent to RL256-TP. Both parts share identical voltage ratings, current ratings, recovery speed, reverse leakage, mounting type, and package configuration. The 0.1 V forward voltage difference and 5 pF capacitance difference are within standard tolerance for general-purpose rectifier applications.

Q: What is the primary difference between RL256-TP and RL256GP-TP?

A: The primary differences are product status and packaging format. RL256-TP is obsolete and supplied in bulk packaging. RL256GP-TP is active and supplied in Tape & Reel format. Electrically, both parts are equivalent with minor parameter variations within acceptable tolerance.

Q: Why is RL256-TP classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The RL256-TP has been superseded by the RL256GP-TP, which offers improved availability and modern packaging standards.

Q: Is Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is standard for automated pick-and-place assembly equipment. If your process requires bulk or alternative packaging, contact the manufacturer to confirm available packaging options for RL256GP-TP.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts share identical operating temperature ranges (-55°C to 150°C junction temperature), moisture sensitivity levels (MSL 1, Unlimited), and compliance certifications (ROHS3, REACH Unaffected).

Q: Can I use RL256GP-TP in high-frequency switching applications?

A: Both parts are rated for Standard Recovery >500ns, > 200mA (Io). This recovery speed is suitable for general-purpose rectification. For high-frequency switching applications requiring faster recovery times, consult the manufacturer for fast-recovery or ultrafast-recovery diode alternatives.

Q: What is the significance of the 0.1 V forward voltage difference?

A: The forward voltage difference (1 V for RL256-TP versus 1.1 V for RL256GP-TP at 2.5 A) represents a 10% variation. This difference is typical among production lots and does not affect general-purpose rectification performance. For applications with strict voltage drop requirements, verify circuit tolerance during design validation.

Q: Are both parts RoHS compliant?

A: Yes. Both RL256-TP and RL256GP-TP are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
