Equivalent & Substitute Parts for RAC05-3.3SC
Part Overview
The RAC05-3.3SC from Recom Power is an enclosed AC/DC converter delivering a single 3.3V output at up to 1.25A (5W). This through-hole module features universal input capability (90 ~ 264 VAC) and is primarily used in ITE (Commercial) applications. The RAC05-3.3SC series is obsolete. Identifying alternative models is necessary for continued production, maintenance, or design-in purposes.

Substitute Part Grouping Explanation
Substitution within this AC/DC converter category is based on matching or exceeding key electrical and mechanical parameters. The following are the strictly considered criteria:
- Output voltage (3.3V)
- Output current (must meet or exceed 1.25A)
- Universal input voltage capability
- Number of outputs (1)
- Enclosed module package
- Through hole mounting
- Compliance with applicable approval and environmental standards
All listed characteristics must be fully met by substitute parts to ensure compatibility in form, fit, and function.

Engineering Selection Recommendations
The RAC05-3.3SC is obsolete and its direct substitute, RAC10-3.3SK/277, is active and meets all key compliance and environmental directives (RoHS3, REACH), with agency approvals listed as CE and cURus. Both modules support universal AC input, single 3.3V output, and through-hole mounting. The RAC10-3.3SK/277 offers higher output current and power ratings and features relevant industry approvals.
Frequently Asked Questions (FAQ)
Q1: Which parameters are critical for substituting AC/DC converter modules in this category?
A1: Key substitution parameters are output voltage, output current, input voltage range, number of outputs, package type, and mounting method.
Q2: Is the package and pinout identical between RAC05-3.3SC and RAC10-3.3SK/277?
A2: The RAC05-3.3SC uses a 5-DIP module (4 Leads) while the RAC10-3.3SK/277 uses a 4-DIP module. Both are through-hole but physical and mechanical compatibility must be confirmed based on provided dimensions and lead arrangement.
Q3: What compliance standards do the substitute parts meet?
A3: Both RAC05-3.3SC and RAC10-3.3SK/277 are ROHS3 compliant and REACH unaffected. Approval agency listings are provided for CE and relevant UL-based certifications.
Q4: Can current higher than 1.25A be supplied by the substitute?
A4: The RAC10-3.3SK/277 offers a maximum output current of 2.5A, which meets or exceeds the requirement.
Q5: Is the substitute suitable for the same applications?
A5: Both parts are designated for ITE (Commercial) applications, with the substitute also supporting household appliances.
Q6: Are environmental and moisture sensitivity levels equivalent?
A6: Both parts are rated at MSL 1 (Unlimited), with identical REACH status.
