Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS26V-R120220 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of Lines: 2 (fixed requirement)
• Current Rating (Max): 1.2A (fixed requirement)
• Voltage Rating - AC: 250V (fixed requirement)
• Operating Temperature Range: -25°C ~ 120°C (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Filter Type: Power Line (fixed requirement)
• Product Status: Active (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)

Variable Parameters Allowing Substitution:

• Inductance @ Frequency: Tolerance range permitted
• DC Resistance (DCR) (Max): Tolerance range permitted
• Physical dimensions: Within mechanical compatibility constraints

The SS26V-R120220 has two identified substitute parts: SS26V-120169 and SS30V-R120380. Both maintain identical electrical ratings for current, voltage, and temperature performance. Inductance values differ to accommodate specific circuit filtering requirements, while DC resistance variations remain within acceptable operational limits for power line applications.

Parameter Comparison

Engineering Selection Recommendations

SS26V-120169 Selection Criteria: This substitute maintains identical physical dimensions (26.00mm x 20.50mm x 30.50mm) and identical DC resistance (550 mOhm) as the main part. The inductance value of 16.9 mH is lower than the 22 mH specification. This part is suitable for applications where reduced inductance filtering is acceptable or required. All electrical ratings, temperature performance, and compliance certifications remain equivalent. PCB layout modifications are not required due to identical footprint dimensions.

SS30V-R120380 Selection Criteria: This substitute provides higher inductance (38 mH) with a slightly increased DC resistance (600 mOhm). Physical dimensions are larger (31.00mm x 22.50mm x 33.00mm), requiring PCB layout verification for mechanical clearance. This part is suitable for applications requiring enhanced filtering performance at the cost of increased component size. All electrical ratings, temperature performance, and compliance certifications remain equivalent. The increased DC resistance of 50 mOhm must be evaluated for thermal and power dissipation impact in the target circuit.

Both substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can SS26V-120169 be used as a direct replacement for SS26V-R120220?

A: Yes, within the constraints of inductance tolerance. Both parts share identical current rating (1.2A), voltage rating (250V), DC resistance (550 mOhm), operating temperature range (-25°C ~ 120°C), and physical dimensions (26.00mm x 20.50mm x 30.50mm). The inductance difference (16.9 mH versus 22 mH) must be evaluated against circuit filtering requirements. No PCB modifications are required due to identical footprint.

Q: What are the mechanical constraints when substituting SS30V-R120380?

A: The SS30V-R120380 has larger dimensions (31.00mm x 22.50mm x 33.00mm) compared to the main part (26.00mm x 20.50mm x 30.50mm). PCB layout must be verified to confirm adequate clearance for the increased length, width, and height. The 4-pin vertical package configuration remains identical, but spatial constraints on the circuit board must be assessed before implementation.

Q: How does DC resistance variation affect circuit performance?

A: The main part and SS26V-120169 both specify 550 mOhm maximum DC resistance. The SS30V-R120380 specifies 600 mOhm maximum, representing a 50 mOhm increase. This resistance contributes to power dissipation in the component. For applications with tight thermal budgets or high continuous current operation at 1.2A, the additional resistance in SS30V-R120380 must be evaluated for acceptable temperature rise and power loss.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part SS26V-R120220 and both substitute parts (SS26V-120169 and SS30V-R120380) are ROHS3 compliant. All parts maintain equivalent regulatory status for environmental and hazardous substance restrictions.

Q: What is the primary difference between the two substitute options?

A: SS26V-120169 provides lower inductance (16.9 mH) with identical physical dimensions and DC resistance, suitable for reduced filtering applications. SS30V-R120380 provides higher inductance (38 mH) with larger physical dimensions and slightly increased DC resistance, suitable for enhanced filtering performance. Selection depends on circuit filtering requirements and available PCB space.

Q: Can these parts be used interchangeably in the same circuit design?

A: No. While all parts share identical electrical ratings (current, voltage, temperature), the inductance values differ significantly (16.9 mH, 22 mH, and 38 mH). Circuit filtering performance depends directly on inductance value. The specific inductance requirement of the circuit design determines which part is appropriate. Additionally, the SS30V-R120380 requires PCB layout verification due to larger dimensions.
