IWD2412 Equivalent & Substitute Parts

Part Overview

The IWD2412 is an isolated module DC-DC converter manufactured by Bel Power Solutions, designed to provide dual output voltages of +12V and -12V from an 18V to 36V input supply. This 10W converter features a 5-DIP module package with through-hole mounting and delivers 500mA on each output channel.

The IWD2412 is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain system continuity, ensure design flexibility, and support procurement of replacement units where original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IWD2412 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range must encompass or match 18V to 36V
• Output voltage configuration must provide +12V and -12V dual outputs
• Output current capacity must meet or exceed 500mA per channel
• Power rating must support the combined load requirements

Mechanical Compatibility Requirements:

• Package type must be 5-DIP Module format
• Through-hole mounting configuration must be maintained
• Physical dimensions must be identical or compatible with existing PCB layouts

Functional Requirements:

• Isolated module topology with dual output capability
• Electrical isolation between input and output stages

The JCK1524D12 satisfies all substitution criteria through matching input voltage range, identical dual output voltage configuration, higher output current capacity (625mA per channel), identical package format, and matching physical dimensions.

Engineering Selection Recommendations

The JCK1524D12 is the manufacturer-recommended substitute for the IWD2412. Selection of this substitute is supported by the following engineering factors:

Electrical Performance: The JCK1524D12 maintains identical input and output voltage specifications while providing increased output current capacity (625mA versus 500mA per channel) and higher power rating (15W versus 10W). This enhanced capability ensures compatibility with existing designs while providing additional performance margin.

Physical Integration: Identical package format (5-DIP Module), mounting type (through-hole), and physical dimensions (2.00" L x 1.00" W x 0.40" H) enable direct substitution without PCB redesign or mechanical rework.

Product Status and Availability: The IWD2412 is obsolete with no active manufacturing. The JCK1524D12 is an active product with confirmed inventory availability (12,400 units), ensuring reliable procurement for current and future applications.

Regulatory Compliance: The JCK1524D12 achieves ROHS3 compliance, whereas the IWD2412 is non-compliant. For applications subject to RoHS requirements, the substitute provides improved regulatory alignment.

Isolation and Protection Features: The JCK1524D12 includes 1.5 kV isolation voltage rating and integrated protection features (OCP, SCP, UVLO) not specified for the IWD2412, providing enhanced system reliability.

Frequently Asked Questions (FAQ)

Q: Can the JCK1524D12 be used as a direct replacement for the IWD2412 in existing designs?

A: Yes. The JCK1524D12 provides identical input voltage range (18V to 36V), matching dual output voltages (+12V and -12V), and identical physical package format (5-DIP Module, 2.00" L x 1.00" W x 0.40" H). No PCB modifications are required for mechanical or electrical integration.

Q: What are the key differences between these two converters?

A: The primary differences are: (1) Output current capacity—JCK1524D12 provides 625mA per channel versus 500mA for the IWD2412; (2) Power rating—JCK1524D12 is rated at 15W versus 10W; (3) Product status—JCK1524D12 is active production while IWD2412 is obsolete; (4) RoHS compliance—JCK1524D12 is ROHS3 compliant while IWD2412 is non-compliant; (5) Protection features—JCK1524D12 includes OCP, SCP, and UVLO protection.

Q: Are there any electrical compatibility concerns when substituting the JCK1524D12 for the IWD2412?

A: No electrical compatibility concerns exist. The JCK1524D12 meets or exceeds all electrical specifications of the IWD2412. The higher output current capacity and power rating of the substitute provide additional design margin without introducing incompatibility.

Q: Does the JCK1524D12 maintain the same isolation characteristics?

A: The JCK1524D12 specifies 1.5 kV isolation voltage. The IWD2412 isolation voltage is not provided in the available specifications. Both devices are isolated module converters with dual outputs, maintaining the isolated topology required for applications using the IWD2412.

Q: What is the operating temperature range for the JCK1524D12?

A: The JCK1524D12 operates across -40°C to 100°C. The IWD2412 operating temperature range is not specified in available documentation.

Q: Are there packaging or procurement differences between these parts?

A: The JCK1524D12 is supplied in tube packaging, while the IWD2412 packaging format is not specified. Both devices use identical 5-DIP Module package format and through-hole mounting. Procurement of the JCK1524D12 is supported by active inventory (12,400 units available), whereas the IWD2412 is obsolete.

Q: What efficiency rating does the JCK1524D12 provide?

A: The JCK1524D12 achieves 88% efficiency. The IWD2412 efficiency rating is not specified in available documentation.
