Equivalent & Substitute Parts Reference for ISP1212

Part Overview

ISP1212 is an isolated DC-DC converter module, designed for ITE (Commercial) applications with two outputs: +12V and -12V at 83mA, efficiency of 78%, and surface mount package. With a product status marked as "Obsolete," sourcing equivalent or substitute DC-DC converters that match its core electrical and mechanical characteristics is essential for maintenance and ongoing production. Alternative models are necessary to ensure continuity where ISP1212 is specified or installed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly by matching essential electrical, mechanical, and compliance parameters. These include output voltages (+12V and -12V), number of outputs, isolated module type, mounting configuration, package dimensions, operating temperature range, voltage isolation, RoHS compliance, and commercial ITE application suitability. Higher input voltage ranges, output currents, and additional features do not preclude substitution unless inconsistent with the application requirements, as only provided parameters are applied for equivalent grouping.

Parameter Comparison

Engineering Selection Recommendations

The ISP1212 is obsolete, as indicated in its product status. ATA00BB18S-L is active and RoHS compliant. Both parts conform to similar isolation voltage, mounting type, package dimensions, and application classification (ITE Commercial). ATA00BB18S-L maintains RoHS environmental compliance as required, with a documented MSL. Provided certifications meet equivalence criteria as presented.

Frequently Asked Questions (FAQ)

Q: What parameters must be matched for a part to replace ISP1212?
A: Substitution requires matching type (Isolated Module), number of outputs, output voltages, input voltage minimum, isolation voltage, operating temperature, mounting type, package/case dimensions, application (ITE Commercial), RoHS compliance, and MSL as supplied.

Q: Is the substitute ATA00BB18S-L compatible with standard ISP1212 footprints?
A: Both use a surface mount package, the same overall dimensions, and fall within the 16-SMD module family, with the ISP1212 using 6 leads and ATA00BB18S-L using 7 leads.

Q: Does the substitute part satisfy regulatory and compliance criteria?
A: ATA00BB18S-L is RoHS compliant and classified under ECCN EAR99, consistent with ISP1212 conformity criteria in the provided data.

Q: Are there differences in output capability or input range?
A: ATA00BB18S-L supports higher output current (125mA per output vs. 83mA) and a broader input voltage maximum (9V-36V vs. 9V-18V). Both support specified +12V and -12V outputs.

Q: What should be verified in terms of mechanical integration?
A: Provided dimensions and surface mount configuration are consistent. The substitute has one additional lead; check provided mechanical drawings for specific pad compatibility based only on the supplied pin count and packaging data.
