Equivalent & Substitute Parts for CM6296-253

Part Overview

The API Delevan Inc. CM6296-253 is an active-status Surface Mount Common Mode Choke (CMC) designed for electromagnetic interference filtering in two-line configurations. This component operates with a 25 µH inductance at 1 kHz, supports 10A maximum current, and features a 14 mOhm DC resistance. The part is RoHS non-compliant and available in bulk packaging with 916 pieces currently in stock.

Identification of alternative models becomes necessary when supply constraints occur, when RoHS3 compliance is required for downstream applications, or when design specifications permit inductance variations within the same footprint and electrical performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for CM6296-253 is governed by the following critical parameters:

Primary Compatibility Criteria:

• Number of Lines: 2 (fixed requirement)
• Current Rating: 10A (maximum limit)
• DC Resistance: 14 mOhm (maximum limit)
• Mounting Type: Surface Mount (fixed requirement)
• Physical Footprint: 26.87mm x 26.87mm x 10.74mm (fixed requirement)
• Package Type: Horizontal, 4 PC Pad (fixed requirement)
• Operating Temperature Range: -55°C ~ 125°C (fixed requirement)
• Moisture Sensitivity Level: 5A (24 Hours) (fixed requirement)

Variable Parameter Tolerance:

• Inductance: Parts with identical (25 µH @ 1 kHz) or alternative inductance values within the same series are classified as parametric equivalents, provided all other parameters remain constant.

Compliance Consideration:

• RoHS Status: Parts meeting RoHS3 compliance standards are identified as direct upgrades for applications requiring regulatory compliance.

Engineering Selection Recommendations

CM6296R-253 (Direct Manufacturer Substitute): CM6296R-253 is the primary alternative for CM6296-253, featuring identical electrical and mechanical specifications with the addition of ROHS3 compliance. Both parts are active-status products from API Delevan Inc. in the CM6296 series. Selection of CM6296R-253 is appropriate when regulatory requirements mandate RoHS3 compliance or when supply of the original CM6296-253 becomes constrained. Current inventory of 1170 pieces is available.

CM6296R-503 (Parametric Equivalent Substitute): CM6296R-503 maintains all mechanical, thermal, and electrical performance criteria of CM6296-253 with the exception of inductance, which increases from 25 µH to 50 µH @ 1 kHz. This part is classified as a parametric equivalent within the CM6296R series and is ROHS3 compliant. Selection of CM6296R-503 applies only to applications where the circuit design accommodates a 50 µH inductance value or where inductance specifications are non-critical. Current inventory of 1158 pieces is available.

Frequently Asked Questions (FAQ)

Q: Can CM6296R-253 directly replace CM6296-253 in production assemblies? A: Yes. CM6296R-253 shares identical electrical and mechanical parameters with CM6296-253, including inductance (25 µH @ 1 kHz), current rating (10A), DC resistance (14 mOhm), footprint (26.87mm x 26.87mm x 10.74mm), and package type (Horizontal, 4 PC Pad). The primary difference is RoHS3 compliance status. Both are active-status products from API Delevan Inc.

Q: What is the difference between a direct manufacturer substitute and a parametric equivalent? A: A direct manufacturer substitute (CM6296R-253) maintains identical specifications across all measured electrical and mechanical parameters. A parametric equivalent (CM6296R-503) preserves critical parameters such as current rating, DC resistance, thermal range, and physical footprint, but allows variation in non-critical parameters, specifically inductance value (50 µH instead of 25 µH).

Q: When should CM6296R-503 be selected instead of CM6296R-253? A: CM6296R-503 substitution is valid only when the application circuit is designed to operate with 50 µH inductance or when inductance specification permits such variation. Selection requires verification that the doubled inductance does not degrade electromagnetic interference filtering performance or introduce unintended circuit behavior. Circuit-level analysis is necessary before substitution.

Q: Are all three parts fully interchangeable in SMD assembly processes? A: CM6296-253 and CM6296R-253 are fully interchangeable in assembly processes due to identical mechanical specifications (footprint, height, and package type). CM6296R-503 is mechanically interchangeable but electrically distinct due to inductance difference and requires circuit-level validation before use.

Q: How does RoHS3 compliance affect part selection? A: RoHS3 compliance affects regulatory qualification for specific market regions and end-use applications. CM6296-253 is RoHS non-compliant, while CM6296R-253 and CM6296R-503 are ROHS3 compliant. Selection depends on whether downstream applications require RoHS3-compliant component documentation or whether non-compliance status is acceptable.

Q: Is moisture sensitivity level identical across all three parts? A: Yes. All three parts share MSL 5A (24 Hours) rating, indicating identical moisture-sensitivity handling and storage requirements during assembly and deployment.
