RAC01-09SC Equivalent & Substitute Parts

Part Overview

The RAC01-09SC is an enclosed AC/DC converter manufactured by Recom Power, part of the POWERLINE RAC01-C (1W) series. This single-output converter delivers 9V at 111mA maximum output current from an 80–264 VAC input, with 1W power rating. The unit features short-circuit protection (SCP) and operates across a temperature range of -25°C to 85°C with derating.

The RAC01-09SC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements for systems utilizing this converter specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RAC01-09SC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Input voltage range: 80–264 VAC
• Output voltage: 9V
• Maximum output current: 111mA
• Power rating: 1W
• Line regulation: ±2%
• Load regulation: ±6%

Mechanical & Package Parameters:

• Mounting type: Through Hole
• Package type: 4-DIP Module
• Physical dimensions: 1.33" L × 0.87" W × 0.71" H (33.7mm × 22.2mm × 18.0mm)

Functional & Compliance Parameters:

• Type: Enclosed
• Number of outputs: 1
• Features: Short-Circuit Protection (SCP)
• Operating temperature range: -25°C to 85°C (With Derating)
• Approval agencies: CE, EN, UL
• RoHS compliance: ROHS3 Compliant

A substitute part must match all electrical specifications, maintain identical mechanical form factor and mounting configuration, and retain all safety certifications and compliance markings. Deviations in any of these parameters disqualify a part from direct substitution.

Engineering Selection Recommendations

The RAC01-09SC is an obsolete product. When selecting a replacement or equivalent part, the following engineering criteria apply:

Compliance & Certification: All substitute parts must retain CE, EN, and UL approval certifications to maintain regulatory compliance in ITE (Commercial) applications. ROHS3 compliance is mandatory for continued market distribution.

Electrical Specification Matching: The substitute must deliver identical input voltage tolerance (80–264 VAC), output voltage (9V), and maximum output current (111mA). Line regulation (±2%) and load regulation (±6%) specifications must be maintained to ensure system stability and performance equivalence.

Mechanical & Form Factor Compatibility: The 4-DIP Module package with through-hole mounting must be preserved. Physical dimensions (1.33" L × 0.87" W × 0.71" H) are critical for PCB layout compatibility. Any deviation in form factor requires circuit board redesign.

Functional Feature Preservation: Short-circuit protection (SCP) functionality must be retained in any substitute to maintain system safety characteristics.

Temperature & Environmental Conditions: Operating temperature range (-25°C to 85°C with derating) and moisture sensitivity level (MSL 1 – Unlimited) must be matched to ensure reliability across specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: What makes a part a true equivalent to the RAC01-09SC?

A: A true equivalent must match all electrical parameters (input voltage 80–264 VAC, output 9V at 111mA, 1W power), maintain the 4-DIP Module through-hole package, operate across -25°C to 85°C, include short-circuit protection, and retain CE, EN, and UL certifications. Any deviation disqualifies the part from direct substitution.

Q: Can I use a different output voltage converter as a substitute?

A: No. The output voltage must be exactly 9V. Using a different voltage rating will cause system malfunction and potential damage to connected circuitry.

Q: Does the 4-DIP Module package matter for substitution?

A: Yes. The package type and physical dimensions are critical for PCB compatibility. A different package form factor requires circuit board redesign and cannot be considered a direct substitute.

Q: What if I find a converter with higher current capacity than 111mA?

A: A higher current rating is acceptable from an electrical standpoint, as it provides additional margin. However, all other parameters must remain identical. The physical package must still be 4-DIP Module with through-hole mounting.

Q: Are RoHS and compliance certifications important for substitution?

A: Yes. ROHS3 compliance and CE, EN, UL certifications are mandatory for ITE (Commercial) applications. A part lacking these certifications cannot be used as a substitute in regulated markets.

Q: Can I substitute with a converter from a different manufacturer?

A: Only if the alternative manufacturer's part meets all specified electrical, mechanical, and compliance parameters. The part number will differ, but all technical specifications must be identical to the RAC01-09SC.

Q: What is the significance of the ±2% line regulation and ±6% load regulation specifications?

A: These specifications define output voltage stability under varying input voltage and load conditions. A substitute must maintain these exact tolerances to ensure system performance equivalence. Wider tolerances indicate inferior regulation and are not acceptable.

Q: Why is the operating temperature range -25°C to 85°C with derating important?

A: This range defines the thermal operating envelope. Derating indicates that performance degrades at temperature extremes. A substitute must support the same temperature range and derating characteristics to ensure reliability across all deployment conditions.
