Equivalent & Substitute Parts for XP Power ISR1212A

Part Overview

The XP Power ISR1212A is an isolated module DC-DC converter designed for commercial ITE applications. It delivers a single 12V output at up to 250mA, accepts an input range from 9V to 18V, and provides 3W maximum output power with short-circuit protection. With surface mount packaging and RoHS3 compliance, it is suitable for environments requiring compact, reliable power conversion. The ISR1212A is classified as obsolete, necessitating the identification of alternative models that meet its exact electrical and mechanical specifications for ongoing or new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution suitability is determined exclusively by matching the following allowed electrical and mechanical parameters: input voltage range (9V–18V), output voltage (12V), output current (250mA), output power (3 W), isolated module type, single output configuration, isolation voltage, mounting type, compliance, and package considerations. Substitute parts are included only if all these parameters correspond within the provided specification.

Parameter Comparison

Engineering Selection Recommendations

The XP Power ISR1212A is obsolete and is no longer available for ongoing designs. The Recom Power REC3-1212SRW/H/B/SMD is active, ROHS3 compliant, and shares compliance status and similar electrical parameters, making it suitable as a substitute. Both parts meet the same moisture sensitivity level and export classification requirements. The substitute part must conform to the required certifications as specified in the parameter comparison.

Frequently Asked Questions (FAQ)

Q: Can REC3-1212SRW/H/B/SMD directly replace ISR1212A in the application?
A: Based solely on the specified electrical and mechanical parameters (input range, output voltage/current, power, isolation, mounting type, and compliance), REC3-1212SRW/H/B/SMD matches the functional requirements of ISR1212A. Package and dimension differences should be considered for mechanical fit.

Q: Are there differences in package format between the main and substitute part?
A: ISR1212A uses a 16-SMD module, 6 leads, while REC3-1212SRW/H/B/SMD has a 24-SMD module, 18 leads. These differences may impact board layout and assembly.

Q: Is the operating temperature range comparable?
A: ISR1212A supports -40°C to 95°C. REC3-1212SRW/H/B/SMD supports -40°C to 85°C. The substitute part operates within a more limited temperature range.

Q: What are the compliance statuses of both parts?
A: Both ISR1212A and REC3-1212SRW/H/B/SMD are ROHS3 compliant and have ECCN EAR99 classification.

Q: Do both parts provide short-circuit protection?
A: Yes, both parts have short-circuit protection features as specified.
