WD202 Equivalent & Substitute Parts Reference

Part Overview

The XP Power WD202 is an obsolete DC DC converter in the isolated module category, providing 12V nominal output at 1.25A from an 18V–36V input range, with a rated power of 15W. As it is no longer in production, sourcing direct replacements is necessary for ongoing designs, repairs, and inventory continuity. Substitute models must meet electrical and mechanical equivalence strictly per provided specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based only on exact alignment with the following key parameters:

• Input voltage range (18V–36V)
• Output voltage and current (12V, 1.25A)
• Output power (15W)
• Module type (Isolated Module)
• Physical footprint (5-DIP Module, Through Hole)
• Application category (ITE Commercial)
• ROHS compliance

All listed substitute parts conform to these definitive requirements. Substitute grouping excludes parts without explicit, matching attributes.

Parameter Comparison

Engineering Selection Recommendations

WD202 is obsolete and not recommended for new designs due to product status. SKA15B-12 is active and ROHS3 compliant, matching all listed electrical, mechanical, and certification fields. The substitute meets explicit catalog compliance and documentation requirements for regulatory and inventory purposes.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when substituting WD202 with SKA15B-12?
All substitute decisions are based on input voltage (18V–36V), output voltage (12V), output current (1.25A), output power (15W), isolated module type, package format (5-DIP Module), mounting type (Through Hole), and RoHS compliance.

Q2: Does the substitute SKA15B-12 fit the same PCB footprint as WD202?
Both parts use a 5-DIP Module with Through Hole mounting. Dimensional variation is within 0.04" in height; the length and width are matched.

Q3: How do certifications and compliance compare for substitution?
Both WD202 and SKA15B-12 are ROHS3 compliant and have the same ECCN and HTSUS codes. Moisture Sensitivity Level is specified for SKA15B-12 (MSL 1, Unlimited).

Q4: Are operating temperature ranges and protection features similar?
Operating temperature overlap exists; SKA15B-12 supports a wider range with derating. Protection features include short-circuit (SCP) for both, with SKA15B-12 also specifying over-voltage protection (OVP).

Q5: Is the SKA15B-12 available for immediate manufacturing needs?
SKA15B-12 is cataloged as Active with inventory listed, meeting substitution requirements for ongoing production.
