Substitute Part Grouping Explanation

Substitutes are selected based strictly on matching the following key parameters: voltage input range (10.8V–13.2V), output voltage (12V), output current (167mA), power (2W), voltage isolation (1.5kV), mounting type (surface mount), package/case (8-SMD Module, 5 Leads), and operating temperature (-40°C ~ 105°C). Mechanical dimensions are closely aligned. RoHS compliance and MSL ratings are also considered for compatibility in modern manufacturing processes.

Engineering Selection Recommendations

Both IES0212S12 and PDS2-S12-S12-M-TR satisfy all provided substitution criteria for ISH1212A-TR, including electrical parameters, mechanical envelope, regulatory compliance, and RoHS conformity. The IES0212S12 provides additional approval certifications (CE, EN, UKCA, UL) and is ROHS3 compliant. The PDS2-S12-S12-M-TR is RoHS compliant and offers similar package and electrical performance with stock availability. Selection may be based on product status (active vs. obsolete), compliance requirements, and inventory availability.

Frequently Asked Questions (FAQ)

Q1: What criteria must substitute DC-DC converters meet for ISH1212A-TR?
A1: Substitutes must match voltage input range (10.8V–13.2V), output voltage (12V), output current (167mA), power (2W), voltage isolation (1.5kV), package type (8-SMD Module, 5 Leads), mounting style (surface mount), operating temperature, RoHS compliance, and similar mechanical dimensions.

Q2: Are there differences in mechanical form factor among substitutes?
A2: All models use an 8-SMD Module, 5 Leads package, with size/dimension differences within stated tolerances for this category.

Q3: What is the importance of product status during substitute selection?
A3: ISH1212A-TR is obsolete; substitute parts are active, which is necessary for ongoing availability in production and maintenance.

Q4: Are there regulatory or environmental considerations in these replacements?
A4: Both substitutes are RoHS compliant and meet the same MSL requirements as the ISH1212A-TR.

Q5: Are there feature or certification differences between the recommended substitutes?
A5: IES0212S12 includes additional certifications (CE, EN, UKCA, UL) and is ROHS3 compliant. PDS2-S12-S12-M-TR is RoHS compliant with EN certification.
