Equivalent & Substitute Parts for RAC04-09SA/277

Part Overview

The Recom Power RAC04-09SA/277 is an enclosed AC/DC converter designed to provide a single regulated 9V output at up to 444mA from a wide input range of 90 to 305 VAC. It is categorized for ITE (commercial) applications, featuring universal input compatibility, compliance with CE, cULus, and EN standards, and mounting in a through-hole 7-DIP module format. The RAC04-09SA/277 is currently obsolete, making it necessary to identify alternative models that match its electrical and mechanical characteristics for ongoing designs and maintenance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for AC/DC converters requires strict correlation of several key parameters, including input voltage range, output voltage and current, power rating, mounting type, regulatory compliance, package or dimensional constraints, and approval agency certification. Substitute parts must match or closely align with these characteristics to ensure compatibility with the intended application and environment.

Key substitution parameters:

• Input voltage range
• Output voltage and maximum current
• Output power rating
• Mounting type (through hole)
• Regulatory and environmental compliance
• Package dimensions and case format
• Approval agency certifications

Parameter Comparison

Engineering Selection Recommendations

Selection between RAC04-09SA/277 and RAC04-09SGB is primarily determined by product status and compliance factors. The RAC04-09SA/277 is obsolete. The RAC04-09SGB is active, with comparable electrical performance, environmental compliance (ROHS3, REACH), and similar agency approvals. All provided information supports direct substitution based strictly on the matched parameters. Package and mounting differences must be confirmed for mechanical compatibility based on provided dimensions and case types.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory parameters to consider when substituting AC/DC converters in this category?
A1: Substitution requires matching input voltage range, output voltage and current, power rating, mounting type, package size, regulatory compliance, and approval agencies.

Q2: Can RAC04-09SGB replace RAC04-09SA/277 without circuit changes?
A2: Both parts provide single 9V outputs at comparable current and power ratings, with through-hole mounting. Mechanical and agency parameters should be used to determine direct compatibility.

Q3: What are the main differences in package and dimensions between RAC04-09SA/277 and RAC04-09SGB?
A3: RAC04-09SA/277 uses a 7-DIP module, 6 leads, while RAC04-09SGB uses a 5-DIP module. Size and lead configuration must be referenced for compatibility.

Q4: What certification differences exist between these two parts?
A4: RAC04-09SA/277 holds CE, cULus, EN approval, while RAC04-09SGB has CE, cURus approval. Selection may be influenced by required agency certifications as listed.

Q5: Are both parts compliant with environmental and safety standards?
A5: Both are ROHS3 compliant, REACH unaffected, and share ECCN EAR99 classification.

Q6: How does the product status affect component selection?
A6: Obsolete status of RAC04-09SA/277 necessitates using active alternatives such as RAC04-09SGB for ongoing production and maintenance.
