SS26V-R100330 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SS26V-R100330 is a 33 mH Common Mode Choke (CMC) manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 1A maximum current with 700 mOhm DC resistance and is rated for 250V AC operation across an operating temperature range of -25°C to 120°C. The part maintains Active product status and is ROHS3 compliant.

Substitute parts are identified when design requirements permit variation in inductance value, DC resistance, current rating, or physical dimensions while maintaining core functional compatibility within the 2-line common mode choke category and through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS26V-R100330 is determined by the following criteria:

Core Compatibility Requirements:

• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Voltage Rating - AC: 250V
• Operating Temperature: -25°C ~ 120°C
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters (Allowable Substitution Range):

• Inductance @ 1 kHz: 9.8 mH to 45 mH
• Current Rating (Max): 1A to 1.2A
• DC Resistance (Max): 600 mOhm to 700 mOhm
• Physical Dimensions: Variations permitted within through-hole vertical mounting constraint

All identified substitute parts maintain identical core specifications for filter application, line configuration, mounting method, voltage rating, temperature range, and regulatory compliance. Variations in inductance, current capacity, and DC resistance reflect different design points within the SS series common mode choke family.

Parameter Comparison

Engineering Selection Recommendations

SS21V-100098 (9.8 mH): Lower inductance value suitable for applications requiring reduced filtering attenuation. Offers improved DC resistance (600 mOhm vs. 700 mOhm) and maintains 1A current rating. Smaller physical footprint. Select when circuit design permits lower inductance specification.

SS21V-R100146 (14.6 mH): Mid-range inductance option providing moderate filtering performance. Reduced DC resistance (600 mOhm) compared to main part. Compact dimensions. Applicable when intermediate inductance values satisfy circuit requirements.

SS28H-R10450-CH (45 mH): Highest inductance value among substitutes, providing maximum filtering attenuation. DC resistance of 650 mOhm. Larger physical dimensions (30.00mm x 30.00mm). Select when enhanced common mode noise suppression is required and board space permits larger component footprint.

SS30V-R120380 (38 mH): Inductance closest to main part specification (38 mH vs. 33 mH). Supports higher current rating (1.2A vs. 1A) with reduced DC resistance (600 mOhm). Larger physical dimensions. Select when increased current capacity or slightly higher inductance is beneficial and space constraints are not limiting.

All substitute parts maintain Active product status, ROHS3 compliance, 250V AC rating, and -25°C to 120°C operating temperature range. Selection depends on specific circuit inductance requirements, current demands, and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can SS21V-100098 replace SS26V-R100330 in all applications?

A: No. SS21V-100098 provides 9.8 mH inductance compared to 33 mH in the main part. Substitution is valid only when circuit design specifications permit lower inductance values. The reduced filtering performance must be evaluated against application requirements.

Q: What is the primary difference between SS28H-R10450-CH and SS26V-R100330?

A: SS28H-R10450-CH provides 45 mH inductance (12 mH higher) with 650 mOhm DC resistance (50 mOhm lower). Physical dimensions are significantly larger (30.00mm x 30.00mm vs. 26.00mm x 20.50mm). Both maintain 1A current rating and identical voltage/temperature specifications.

Q: Is SS30V-R120380 a direct replacement for SS26V-R100330?

A: SS30V-R120380 is functionally compatible but not identical. It provides 38 mH inductance (5 mH higher), supports 1.2A current (0.2A higher), and has reduced DC resistance (600 mOhm vs. 700 mOhm). Physical dimensions are larger. Substitution is valid when higher current capacity is beneficial or neutral to circuit operation.

Q: Do all substitute parts fit the same PCB footprint?

A: No. Physical dimensions vary across the substitute parts. SS21V series components are more compact (20.50mm x 16.50mm) than the main part (26.00mm x 20.50mm). SS28H-R10450-CH and SS30V-R120380 are larger. PCB layout verification is required before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance status, matching the main part specification.

Q: What determines whether a part qualifies as a substitute?

A: Substitutes must maintain identical specifications for filter type (Power Line), line configuration (2-line), mounting method (Through Hole), package style (Vertical, 4 PC Pin), AC voltage rating (250V), operating temperature range (-25°C to 120°C), and regulatory compliance (ROHS3). Inductance, current rating, and DC resistance may vary within the SS series design envelope.
