CFM1007S AC/DC Converter 3.3V 10W Equivalent & Substitute Parts

Part Overview

The CFM1007S is an open frame AC/DC converter manufactured by Cincon Electronics Co. LTD, designed to deliver 3.3V at 2.5A maximum output current with 10W power rating. This unit accepts universal AC input (85–264 VAC) and is intended for ITE (Commercial) applications. The CFM1007S carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and new design implementations where this topology remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CFM1007S is constrained by the following critical parameters:

Output Voltage Compatibility: The substitute must deliver 3.3V output to maintain circuit compatibility with downstream components and systems designed for this voltage level.

Output Current Capacity: The substitute must support the maximum output current requirement. The CFM1007S delivers 2.5A; substitutes with lower current ratings (such as 1.5A) represent a reduction in available power delivery capacity and are classified as partial or conditional substitutes.

Input Voltage Range: The CFM1007S accepts 85–264 VAC universal input. Substitutes must cover this range or a compatible superset to ensure operation across the same mains voltage conditions.

Form Factor and Mounting: Both the main part and substitute must be open frame modules with through-hole mounting to ensure physical and electrical compatibility with existing PCB layouts.

Regulatory Compliance: Substitutes must maintain equivalent or superior certification status (CE, cURus, TUV, or equivalent) to satisfy the same regulatory requirements.

The CFM06S033 is identified as a manufacturer-recommended substitute. However, this substitute exhibits reduced output current capacity (1.5A versus 2.5A) and lower power rating (5W versus 10W), making it suitable only for applications where the lower current and power specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Output Current and Power Capacity

The CFM06S033 substitute is rated for 1.5A maximum output current and 5W power, compared to the CFM1007S specification of 2.5A and 10W. Selection of the CFM06S033 is appropriate only when the application load current does not exceed 1.5A. Applications requiring the full 2.5A capacity of the CFM1007S cannot be satisfied by the CFM06S033 without risk of converter overload and potential thermal shutdown or component failure.

Regulatory and Compliance Status

Both the CFM1007S and CFM06S033 maintain ROHS3 compliance and carry CE certification. The CFM06S033 additionally holds cURus, D-Mark, and FCC certifications, providing broader regulatory acceptance. The CFM1007S carries TUV certification, which the CFM06S033 does not list. For applications requiring TUV certification specifically, the CFM1007S remains the required choice.

Product Availability and Lifecycle

The CFM1007S is classified as obsolete, indicating discontinued manufacture. The CFM06S033 is classified as active and currently in production, making it the preferred substitute for new designs and long-term supply continuity where output current requirements permit.

Physical Form Factor

The CFM1007S is specified as a Module package (2.60" L × 1.77" W × 0.91" H). The CFM06S033 is specified as a 4-DIP Module (1.56" L × 0.76" W × 0.72" H). The significant difference in physical dimensions requires PCB layout modification and may not be suitable for space-constrained applications designed around the CFM1007S footprint.

Regulation Performance

The CFM1007S provides line regulation of ±0.5% and load regulation of ±1%. The CFM06S033 provides line regulation of ±1% and load regulation of ±6%. Applications requiring tight output voltage stability should retain the CFM1007S if available, or source alternative converters with comparable regulation specifications.

Temperature Operating Range

The CFM06S033 operates across −40°C to 80°C, exceeding the CFM1007S range of 0°C to 70°C. For applications requiring extended low-temperature operation below 0°C, the CFM06S033 provides superior capability.

Frequently Asked Questions (FAQ)

Q: Can the CFM06S033 directly replace the CFM1007S in an existing design?

A: Direct replacement is possible only if the application load current does not exceed 1.5A. The CFM06S033 is rated for 1.5A maximum output current, compared to the CFM1007S rating of 2.5A. If the existing design draws more than 1.5A from the 3.3V output, the CFM06S033 will not function reliably. Additionally, the CFM06S033 has a smaller physical footprint (1.56" L × 0.76" W × 0.72" H versus 2.60" L × 1.77" W × 0.91" H), requiring PCB layout modification.

Q: What is the significance of the CFM06S033 being rated at 5W versus the CFM1007S at 10W?

A: The power rating reflects the maximum continuous power the converter can deliver. The CFM1007S can deliver up to 10W (2.5A at 3.3V), while the CFM06S033 can deliver up to 5W (1.5A at 3.3V). Applications requiring more than 5W output power cannot use the CFM06S033.

Q: Does the CFM06S033 accept the same input voltage range as the CFM1007S?

A: The CFM1007S accepts 85–264 VAC input. The CFM06S033 accepts 90–264 VAC input, which is slightly narrower at the lower end (90 VAC versus 85 VAC). For applications operating at input voltages below 90 VAC, the CFM1007S is required. The CFM06S033 additionally accepts 120–370 VDC input, a capability not specified for the CFM1007S.

Q: Why does the CFM06S033 have different load regulation (±6%) compared to the CFM1007S (±1%)?

A: Load regulation describes how much the output voltage changes as the load current varies. The CFM1007S maintains tighter output voltage stability (±1% variation) across load changes, while the CFM06S033 allows ±6% variation. Applications sensitive to output voltage fluctuations under varying load conditions should retain the CFM1007S or select an alternative converter with comparable regulation performance.

Q: Is the CFM06S033 suitable for applications requiring TUV certification?

A: The CFM1007S lists TUV certification; the CFM06S033 does not. If TUV certification is a regulatory requirement, the CFM06S033 cannot be used as a substitute. The CFM06S033 does carry CE, cURus, D-Mark, and FCC certifications, which may satisfy other regulatory pathways.

Q: What are the physical mounting differences between these converters?

A: Both converters use through-hole mounting. However, the CFM1007S is a Module package measuring 2.60" L × 1.77" W × 0.91" H, while the CFM06S033 is a 4-DIP Module measuring 1.56" L × 0.76" W × 0.72" H. The CFM06S033 is significantly smaller and has a different pin configuration. PCB layout modification is required for substitution.

Q: Can I use the CFM06S033 in applications operating below 0°C?

A: The CFM1007S is rated for 0°C to 70°C operation. The CFM06S033 is rated for −40°C to 80°C operation. For applications requiring operation below 0°C, the CFM06S033 provides the necessary temperature capability, while the CFM1007S does not.

Q: Why is the CFM1007S classified as obsolete?

A: The CFM1007S is no longer manufactured by Cincon Electronics Co. LTD. Obsolete status indicates end-of-life for this product line. The CFM06S033 is classified as active and currently in production, making it the recommended path for new designs and long-term supply assurance where specifications permit substitution.
