Equivalent & Substitute Parts for VDSD1-S5-DI9-SIP

Part Overview

The VDSD1-S5-DI9-SIP from CUI Inc. is an isolated module DC-DC converter featuring dual outputs of +9V and -9V, each rated for a maximum output current of 56mA, with a total power rating of 1W. The device operates over an input voltage range of 4.5V to 5.5V and offers 1 kV isolation. Additional features include short circuit protection (SCP), through-hole mounting, and compliance with cURus approval. This part is classified as obsolete. The obsolete status necessitates identification of an equivalent substitute with matching specifications for continued production and field replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is defined strictly by matching the following key parameters: output configuration (dual output, +9V and -9V, 56mA each), input voltage range (4.5V to 5.5V), isolation rating (1 kV), total output power (1W), operational temperature (-40°C to 85°C), ITE application suitability, mounting type (through-hole), and geometric dimensions consistent with SIP packaging standards. Only parts meeting all these specified parameters are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The VDSD1-S5-DI9-SIP is obsolete, which precludes its use in new designs or future procurement cycles. MEA1D0509SC is active, ROHS3 compliant, and unaffected by REACH, facilitating continued use in commercial ITE environments. Both devices conform to provided mechanical, electrical, and environmental specifications. Differences in approval agency marking (cURus versus none specified for the substitute) and lead count in package/case exist; all other critical parameters are matched as allowed in the category.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting the VDSD1-S5-DI9-SIP?
A1: Substitution requires matched specifications for input voltage range, dual output voltages (+9V, -9V) and currents (56mA each), output power (1W), isolation voltage (1kV), temperature range (-40°C to 85°C), through-hole SIP package, and suitability for ITE (Commercial) applications.

Q2: Are differences in package lead count allowed when selecting a substitute?
A2: Substitution is based strictly on the allowed SIP form factor, mounting type, and external dimensions provided. Minor differences in lead count are permitted if the function and interface are retained according to the specified parameters.

Q3: How does product status affect substitution choice?
A3: Only active status products are considered suitable substitutes for obsolete items to ensure ongoing availability for design and replacement.

Q4: What compliance or certifications are relevant in selecting substitutes?
A4: Substitute selection incorporates provided certifications and product compliance status, such as RoHS3 and REACH, when explicitly specified.

Q5: Are differences in efficiency considered during substitution?
A5: Efficiency is part of the provided comparison; the substitute part meets or exceeds the original part's efficiency specification as allowed by the parameters.
