MEAN WELL SPA02B-12 Equivalent & Substitute DC-DC Converter Reference

Part Overview

The MEAN WELL USA Inc. SPA02B-12 is an Isolated Module DC-DC Converter providing a single 12V output at up to 167mA from an 18V–36V input, rated at 2W. Its features include 1kV isolation, remote on/off control, overcurrent protection (OCP), short-circuit protection (SCP), 80% efficiency, through-hole 8-SIP mounting, and an operating temperature range from –40°C to +85°C (with derating). The SPA02B-12 is obsolete; identifying direct equivalents and substitutes is necessary for ongoing production, design-in, and long-term maintenance where identical form, fit, and function are required.

Substitute Part Grouping Explanation

Substitute DC-DC converter models are included based strictly on electrical and mechanical compatibility: identical or matching output voltage, current, power, number of outputs, input voltage range, features, isolation rating, package, size, and compliance. Only parts matching these requirements and sharing the 8-SIP Module, 7 Leads through-hole package are classified as direct equivalents or substitutes. Compliance to ROHS3, REACH, and MSL 1 requirements is also mandatory for inclusion.

Key parameters for equivalence:

  • Output voltage: 12V
  • Output current: at least 166–167mA
  • Power: 2W
  • Input voltage range compatibility
  • Isolation voltage equal to or greater than 1kV
  • Single output
  • Package: 8-SIP Module, 7 Leads
  • Features: remote on/off, protection features (OCP, SCP)
  • Operating temperature range
  • Mounting type: through hole
  • Regulatory and RoHS/REACH compliance

Engineering Selection Recommendations

Select substitute parts with equal or better RoHS3, REACH, and ECCN compliance status when the original component is obsolete. SPAN02B-12 and RS-1212S/H3 are both compliant with all provided certifications (RoHS3 Compliant, REACH Unaffected, MSL 1, EAR99), match the package type, and maintain consistent output specifications. Confirm product status for long-term availability.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the SPA02B-12 DC-DC Converter?
A1: Substitution is based on output voltage (12V), output current and power ratings (2W, ≥166mA), single output, input voltage range, isolation voltage, package (8-SIP Module, 7 Leads), features, operating temperature range, and RoHS/REACH compliance.

Q2: Are the form factor and mounting style consistent between the original and substitute parts?
A2: Yes, all substitute parts use the 8-SIP Module, 7 Leads through-hole package footprint with identical size and dimensions.

Q3: Do substitute parts match the compliance and certifications of the original?
A3: Yes, SPAN02B-12 and RS-1212S/H3 are ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and classified under ECCN: EAR99.

Q4: Which substitute part offers identical electrical characteristics?
A4: SPAN02B-12 matches all relevant electrical, mechanical, and compliance parameters for direct substitution.

Q5: Is there any functional or application-level difference between the substitutes?
A5: All substitutes provide ITE (Commercial) application support and core protection features as specified in the input parameters. Care should be taken to match the input voltage range as required by the system.

Q6: Are there supply or inventory considerations for the alternatives?
A6: Substitute parts listed are active and currently in stock. Confirm inventory status before final selection.
