Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified and validated strictly based on the following parameters: output voltage (9V), output current (111mA), input voltage range (10.8V–13.2V), output power (1W), number of outputs (1), isolation voltage (3kV), mounting type (surface mount), package type (12-SMD Module, 10 Leads), RoHS status (ROHS3 Compliant), moisture sensitivity level (1), REACH status, and general application suitability (ITE commercial). Only units matching across these defined fields are considered valid equivalents.

Parameter Comparison

Engineering Selection Recommendations

The SFT01M-09 is classified as obsolete, while the substitute part R1S12-1209/H-R is active and available. Both parts conform to ROHS3 and REACH standards and share moisture sensitivity level 1 ratings. For continued reliability, regulatory compliance, and inventory continuity, select R1S12-1209/H-R as the direct replacement where all matching technical, packaging, and environmental criteria are satisfied.

Frequently Asked Questions (FAQ)

Q1: What key electrical parameters must match when substituting SFT01M-09?
A1: Output voltage (9V), output current (111mA), input voltage range (10.8V–13.2V), power (1W), isolation voltage (3kV), and number of outputs (1) are the mandatory matching values.

Q2: Are there differences in features between SFT01M-09 and R1S12-1209/H-R?
A2: The SFT01M-09 offers OCP and SCP, while R1S12-1209/H-R specifies SCP. Features should be reviewed per application requirements.

Q3: Is the mounting style and package type the same for both parts?
A3: Both modules use surface mount (12-SMD Module, 10 Leads), supporting direct compatibility with PCB footprints designed for SFT01M-09.

Q4: What are the relevant compliance statuses?
A4: Both modules are ROHS3 compliant, have moisture sensitivity level 1, and are REACH unaffected.

Q5: Why must substitutes be selected strictly by parameters?
A5: Substitution relies on matching the specified electrical characteristics, package dimensions, and compliance statuses to ensure functional and regulatory equivalence.

Q6: Does thermal performance differ?
A6: Operating temperature ranges differ; verify compatibility with end-use environmental requirements based strictly on the rated ranges provided.

Q7: Does size variation affect compatibility?
A7: Width and height differ slightly between models; ensure mechanical fit within existing enclosure and PCB layouts.
