Key Parameters

Substitute Part Grouping Explanation

Substitute parts for NMK1209SAC are grouped strictly according to electrical and mechanical compatibility. The following parameters are used to determine a valid substitution: output voltage (9V), output current (222mA), input voltage range (10.8V–13.2V), isolation rating (≥3 kV), package type (7-SIP Module, 4 Leads), mounting type (through hole), RoHS and REACH compliance, and compatible operating temperature range. Compatibility in these specifications ensures substitutes will perform as direct replacements in the intended applications.

Parameter Comparison

Engineering Selection Recommendations

NMK1209SAC holds an obsolete status, while substitute model MEJ2S1209SC is active and maintains required compliance with ROHS3 and REACH. Both models utilize a through-hole 7-SIP Module, 4 Leads package and share primary electrical ratings, ensuring substitute suitability based on supported international certification and regulatory standards.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting NMK1209SAC in existing designs?
A: Key substitution criteria include matching output voltage (9V), output current (222mA), input voltage range (10.8V–13.2V), isolation voltage (equal or higher), compatible package dimensions (7-SIP Module, 4 Leads), mounting type (through hole), compliance with ROHS3 and REACH, and matching operating temperature range (-40°C ~ 85°C).

Q: Is the MEJ2S1209SC form-factor compatible with NMK1209SAC?
A: MEJ2S1209SC features the same 7-SIP Module, 4 Leads through-hole package, supporting direct mechanical compatibility.

Q: Does the substitute offer comparable isolation voltage?
A: MEJ2S1209SC provides a higher isolation voltage (5.2 kV vs. 3 kV), supporting substitution in applications requiring at least 3 kV.

Q: Are RoHS and REACH compliance maintained with the substitute?
A: Both NMK1209SAC and MEJ2S1209SC declare ROHS3 compliance and REACH unaffected status.

Q: Can the substitute handle identical output and input ratings?
A: MEJ2S1209SC provides identical output voltage and current ratings, as well as the same input voltage range as NMK1209SAC.
