ISH1212A-H Equivalent & Substitute Parts Reference

Part Overview

The ISH1212A-H by XP Power is an isolated DC-DC converter module, specified for a single 12V output at 167mA, with a 10.8V–13.2V input range, 2W rated power, and 3 kV isolation. This module is now classified as obsolete. Alternate and substitute models must be identified to ensure ongoing product support and supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter models are identified strictly based on the matching of key electrical parameters, mounting style, mechanical package, and compliance status. Parameters considered are: manufacturer, type (isolated module), number of outputs, input and output voltage, maximum output current, power, voltage isolation, intended application, operating temperature range, efficiency, surface mount type, package/case, size/dimension, and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection between ISH1212A-H alternatives should reference the product status. ISH1212A-H is obsolete; both IES0212S12 and ISV0212S12 are listed as active. Both alternative models are from XP Power and share RoHS3 compliance for restricted substance requirements. Where regulatory certification is relevant, IES0212S12 provides CE, EN, UKCA, and UL approvals. The IES0212S12 differs in voltage isolation (1.5kV versus 3kV). ISV0212S12 maintains the 3kV isolation but uses a different case (6-SMD Module) and offers a wider input range.

Frequently Asked Questions (FAQ)

Q: What core electrical parameters must be matched for DC-DC converter substitution in this category?
A: Key parameters are input voltage range, output voltage, output current, rated power, isolation voltage, number of outputs, mounting type, and package/case.

Q: How do package and mounting differences impact substitution?
A: Surface-mount compatibility is retained in all listed alternatives. Dimensional and lead differences must be reviewed against system PCB layout constraints, especially where package or footprint varies.

Q: What are the isolation voltage considerations?
A: ISH1212A-H and ISV0212S12 both offer 3 kV isolation, while IES0212S12 provides 1.5 kV. Selection is determined by system isolation requirements.

Q: Which substitute model maintains the same or wider operating temperature range?
A: IES0212S12 matches the -40°C to 105°C range (with derating), while ISV0212S12 supports -40°C to 75°C.

Q: How does input voltage flexibility differ between variants?
A: ISH1212A-H and IES0212S12 accept 10.8V–13.2V input; ISV0212S12 supports a broader range of 4.5V–18V.

Q: Are all substitute parts compliant with RoHS requirements?
A: ISH1212A-H and ISV0212S12 are specified as ROHS3 Compliant. RoHS status for IES0212S12 is not explicitly listed in the supplied parameters.

Q: What certifications are available for the substitute parts?
A: IES0212S12 lists CE, EN, UKCA, and UL certifications. ISV0212S12 does not list certification in the provided data.
