Equivalent & Substitute Parts Reference for SPA02E-12
Part Overview
SPA02E-12 is an isolated DC-DC converter module manufactured by MEAN WELL USA Inc. It provides a single 12V output at up to 150mA from a 4.5V to 9V input, with 1.8W power rating and 1kV isolation voltage. This module is packaged as an 8-SIP Module with 7 leads and is suitable for commercial ITE applications, featuring remote on/off, overcurrent protection (OCP), and short circuit protection (SCP). The module is ROHS3 compliant, has unlimited moisture sensitivity (MSL 1), and is designated as obsolete. Due to its obsolete status, identifying direct and similar substitutes is required for continued production and maintenance activities.

Engineering Selection Recommendations
SPA02E-12 is classified as obsolete. Substitute selection is strictly limited to models that match all specified compliance requirements (ROHS3, REACH, unlimited MSL), mounting type, package, and electrical ratings. SPAN02E-12 maintains compatibility across all electrical and mechanical criteria and is currently active in production. RS-0512S/H3 also matches all specified requirements and compliance certifications, with increased isolation voltage and additional medical application approval.
Frequently Asked Questions (FAQ)
Q1: What criteria determine whether a substitute is valid for SPA02E-12?
A: Valid substitutes must strictly match input voltage range, output voltage, output current rating, isolation voltage, package (8-SIP Module, 7 Leads), mounting type, application suitability, ROHS/REACH compliance, and unlimited MSL.
Q2: Are the substitute parts form, fit, and function compatible with SPA02E-12?
A: All listed substitutes use the same 8-SIP Module, 7 Leads package, matching the mechanical dimensions and electrical interfaces required for direct replacement.
Q3: Do substitute parts provide equal or higher performance ratings?
A: Both SPAN02E-12 and RS-0512S/H3 meet or exceed main part output current, wattage, efficiency, and isolation voltage parameters.
Q4: Is soldering or assembly process affected by the substitute selection?
A: All listed substitute modules are through-hole, MSL 1 (unlimited), and ROHS3 compliant, ensuring process compatibility with SPA02E-12.
Q5: Are the listed substitutes currently available?
A: Both SPAN02E-12 and RS-0512S/H3 are listed as active and have inventory available.
