Equivalent & Substitute Parts Reference: ISP1209A

Part Overview

The ISP1209A by XP Power is an isolated module DC-DC converter delivering a single 9V output at a maximum current of 222mA, with an input voltage range of 9V to 18V. It is rated at 2W power output with 1.5kV isolation, designed for ITE (Commercial) applications, featuring short circuit protection (SCP), and supports operating temperatures from -40°C to 85°C. The device is now classified as Obsolete, necessitating identification of substitute models for continued design maintenance, repair, or new production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly defined by matching the explicit electrical and mechanical parameters provided. The substitute part, REC3-1209SRW/H/B/SMD, is included based on the following criteria:

• Type: Isolated Module
• Number of Outputs: 1
• Voltage - Input (Min): 9V
• Voltage - Input (Max): 18V
• Voltage - Output 1: 9V
• Voltage - Isolation: ≥1.5kV
• Applications: ITE (Commercial)
• Features: SCP (Short Circuit Protection)
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• RoHS Status and MSL compliance

Parameters matched ensure direct substitution for function, safety isolation, application, and compliance categories.

Parameter Comparison

Engineering Selection Recommendations

Given the obsolete status of ISP1209A, selection of substitute parts must be based on current availability, RoHS compliance, and moisture sensitivity level (MSL). Only substitute models that are explicitly RoHS3 compliant with MSL 1 (Unlimited) provide direct compatibility for certified and industry-compliant production environments. Product status must be active to ensure ongoing supply chain reliability.
