Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76600/3C is determined by the following critical parameters:

• Inductance tolerance: The substitute must operate within acceptable inductance range relative to the 219µH specification
• Turns ratio: Must maintain 1:1 primary to secondary configuration
• Mounting type: Through-hole mounting compatibility is required for PCB integration
• Physical envelope: Dimensions must not exceed 0.500" L x 0.350" W x 0.250" H to ensure mechanical fit within existing designs
• Electrical characteristics: ET (Volt-Time) product and operating temperature range should align with application requirements

The Newava Technology Inc. S22083 meets these substitution criteria through matching turns ratio, mounting type, and physical dimensions, with inductance of 225µH representing a 2.7% variance from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Newava Technology Inc. S22083 is the qualified substitute for the obsolete Murata Power Solutions 76600/3C. Selection is based on the following factors:

• Product status alignment: The S22083 maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory compliance: Both components share EAR99 export classification and are not subject to REACH restrictions
• Physical compatibility: Identical mounting footprint and through-hole configuration enable direct PCB layout compatibility
• Electrical equivalence: Matching 1:1 turns ratio and identical physical envelope ensure functional interchangeability within the specified operating parameters

The 225µH inductance of the S22083 represents a 2.7% increase relative to the 219µH specification of the 76600/3C. This variance falls within typical component tolerance ranges for pulse transformer applications and does not introduce incompatibility with standard circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the S22083 be used as a direct replacement for the 76600/3C in existing designs?

A: Yes. The S22083 matches the critical substitution parameters: 1:1 turns ratio, through-hole mounting, and identical physical dimensions (0.500" L x 0.350" W x 0.250" H). The 2.7% inductance variance (225µH vs. 219µH) is within acceptable tolerance for general purpose pulse transformer applications.

Q: What is the significance of the inductance difference between these parts?

A: The 76600/3C specifies 219µH while the S22083 provides 225µH. This 6µH difference represents a 2.7% variance. For pulse transformer applications, this level of inductance tolerance is standard and does not affect circuit functionality when the design accommodates typical component tolerances.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical ECCN classification (EAR99) and Moisture Sensitivity Level (Not Applicable). The S22083 carries RoHS Compliant certification, providing additional environmental compliance assurance for new designs.

Q: What packaging options are available for the S22083?

A: The S22083 is supplied in tube packaging, which is standard for through-hole transformer components and compatible with automated assembly processes.

Q: Why is the 76600/3C classified as obsolete?

A: The 76600/3C has reached end-of-life status with Murata Power Solutions. The S22083 from Newava Technology Inc. is the recommended active production alternative that maintains electrical and mechanical compatibility.
