REC15-4812D/H2 Equivalent & Substitute Parts

Part Overview

The REC15-4812D/H2 is an isolated module DC-DC converter from Recom Power's ECONOLINE REC15 series, delivering dual output voltages of +12V and -12V at 625mA each from a 36V to 75V input supply. This 15W converter is designed for commercial ITE applications and features remote on/off control, output current protection (OCP), and short-circuit protection (SCP).

The REC15-4812D/H2 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for system maintenance, production continuity, and design updates where component sourcing becomes constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the REC15-4812D/H2 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Input voltage range: 36V to 75V
• Dual output configuration: +12V and -12V
• Output current capacity: 625mA per output
• Power rating: 15W
• Isolation voltage: 2 kV
• Operating temperature range: -40°C to +71°C
• Efficiency: 86%

Mechanical and Interface Specifications:

• Mounting type: Through Hole
• Package type: 6-DIP Module
• Physical dimensions: 50.8mm × 25.4mm × 10.2mm
• Control interface: Enable, Active High

Compliance and Regulatory:

• RoHS3 Compliance
• REACH Unaffected status
• ECCN: EAR99
• HTSUS: 8504.40.9580

Substitute parts must maintain identical electrical performance, physical form factor, and regulatory compliance to ensure direct interchangeability without circuit redesign or board layout modification.

Engineering Selection Recommendations

REC15-4812D/H2/M as Primary Substitute:

The REC15-4812D/H2/M is the direct functional equivalent of the obsolete REC15-4812D/H2. Both parts share identical electrical specifications, physical dimensions, and mounting characteristics. The REC15-4812D/H2/M is currently in active production status with confirmed inventory availability.

The REC15-4812D/H2/M includes an additional protection feature (UVLO—Under-Voltage Lock-Out) not present in the original part. This enhancement provides additional circuit protection without affecting electrical or mechanical compatibility. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for commercial ITE applications.

The primary distinction between the two parts is packaging: the REC15-4812D/H2/M is supplied in tube packaging, whereas the original part was supplied in standard packaging. This packaging difference does not affect electrical performance or board-level integration.

For new designs or component replacement in existing systems, the REC15-4812D/H2/M is the appropriate selection due to its active product status and enhanced protection features.

Frequently Asked Questions (FAQ)

Q: Can the REC15-4812D/H2/M be used as a direct replacement for the REC15-4812D/H2?

A: Yes. The REC15-4812D/H2/M is electrically and mechanically identical to the REC15-4812D/H2. Both parts deliver +12V and -12V outputs at 625mA each from a 36V to 75V input, operate across the same temperature range, and use the same 6-DIP through-hole package with identical physical dimensions. No circuit redesign or board layout modification is required.

Q: What is the difference between the REC15-4812D/H2 and REC15-4812D/H2/M?

A: The REC15-4812D/H2/M includes an additional UVLO (Under-Voltage Lock-Out) protection feature and is supplied in tube packaging. The original REC15-4812D/H2 does not include UVLO protection. All other electrical and mechanical specifications are identical.

Q: Why is the REC15-4812D/H2 listed as obsolete?

A: The REC15-4812D/H2 has been discontinued by Recom Power. The REC15-4812D/H2/M is the active production equivalent and is the recommended part for new applications and component replacement.

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

A: No. Both the REC15-4812D/H2 and REC15-4812D/H2/M are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Q: What is the significance of the "/M" designation in the part number?

A: The "/M" suffix indicates the part is supplied in tube packaging and belongs to the ECONOLINE REC15/M series variant. The electrical and mechanical specifications remain unchanged from the base REC15-4812D/H2 design.

Q: Can I use the REC15-4812D/H2/M in applications originally designed for the REC15-4812D/H2?

A: Yes. The REC15-4812D/H2/M is a direct substitute for all applications using the REC15-4812D/H2. The additional UVLO protection feature provides enhanced reliability without affecting compatibility.

Q: What is the isolation voltage rating, and why is it important?

A: Both parts provide 2 kV isolation voltage, which establishes the maximum voltage difference that can be safely applied between the input and output circuits. This rating is critical for applications requiring galvanic isolation between power domains.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts measure 50.8mm length × 25.4mm width × 10.2mm height and use the same 6-DIP through-hole mounting configuration. They are mechanically interchangeable on PCBs designed for either part.
