Equivalent & Substitute Parts Reference: MEAN WELL USA Inc. SPR01L-12

Part Overview

The MEAN WELL USA Inc. SPR01L-12 is an isolated module DC-DC converter delivering 1W power with a single 12V output at up to 84mA, operating from a 4.5V–5.5V input. The product status is “Obsolete,” which necessitates the identification of alternative models to ensure continued BOM availability and production continuity. Finding a substitute with matching or surpassing electrical and mechanical specifications is critical for design replacement.

Key Parameters

Substitute Part Grouping Explanation

The substitute part SPRN01L-12 is grouped based exclusively on electrical and mechanical parameter alignment with SPR01L-12. Substitution is based on:

• Isolated Module type
• 1 output
• Input voltage covering the needed range
• Identical output (12V, 84mA)
• Equivalent or greater power rating
• Through hole mounting
• Exact match in 6-SIP Module, 4 Leads package and overall dimensions
• ROHS3 compliance and MSL 1 status
  Only these allowed parameters are considered to ensure the substitute is functionally and physically compatible without deviation.

Parameter Comparison

Engineering Selection Recommendations

SPR01L-12 is currently obsolete, while SPRN01L-12 is active and available. Both parts are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited). SPRN01L-12 also holds additional certifications (CE, EAC, UKCA). Selection is based on product status and compliance as detailed; alternate selection criteria are not included.
