Key Parameters

Substitute Part Grouping Explanation

Substitution logic is determined strictly by the following allowed parameters: type (isolated module), number of outputs (1), input voltage range (10.8V–13.2V), output voltage (12V), output current (≥83mA), output power (≈1 W), voltage isolation (≥3 kV), mounting type (through hole), package/case format (7-SIP Module, 4 Leads), and regulatory compliance status. Only components matching these key engineering parameters qualify as substitutes within the isolated DC DC converter category.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts have active product status, RoHS compliance, and MSL rating of 1 (Unlimited). Both PEM1-S12-S12-S and PEME1-S12-S12-S provide CB Scheme, EN, IEC, UL, CE, and cURus approval agency coverage, while RP-1212S offers ROHS3 compliance and ITE/Medical application suitability. Certification alignment should be verified against system requirements based on the provided information.

Frequently Asked Questions (FAQ)

What key parameters determine substitute eligibility for PEM1-S12-S12-S?

Substitution is based on matching type (isolated module), number of outputs (1), input voltage range (10.8V–13.2V), output voltage (12V), output current (≥83mA), output power (≈1 W), voltage isolation (≥3 kV), mounting style, package/case, RoHS compliance, and moisture sensitivity rating.

Are there significant mechanical differences between these substitutes?

All parts share the 7-SIP Module, 4 Leads package and through-hole mounting, with slight dimensional variations as specified in the key parameter comparison.

What regulatory certifications are covered by these substitutes?

PEM1-S12-S12-S and PEME1-S12-S12-S have CB Scheme, EN, IEC, UL, CE, cURus approvals; RP-1212S specifies ROHS3 compliance and ITE/Medical suitability. Certification should be selected as required by system-level standards.

Is efficiency a consideration in substitution?

Efficiency ranges from 78% to 80% across models, within typical tolerance for this category, and must align with specification requirements as listed.

Do all substitutes support single output at 12V?

Yes. All listed substitutes provide a single 12V output within the allowed current and power specifications.

Is the voltage isolation specification consistent?

PEM1-S12-S12-S and PEME1-S12-S12-S have 3 kV isolation; RP-1212S offers 5.2 kV. All meet or exceed the main part’s specified value.

Are mounting styles or packaging types consistent?

Yes. All substitutes utilize through-hole mounting and the 7-SIP Module, 4 Leads format per specifications provided.
