41206ESDA-TR1 Equivalent & Substitute Parts

Part Overview

The 41206ESDA-TR1 is a Transient Voltage Suppressor (TVS) device manufactured by Eaton - Electronics Division, utilizing polymer technology in a 1206 surface mount package. This component is designed for general-purpose circuit protection applications with a clamping voltage of 35V and four integrated circuits. The part is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement planning. Substitute parts must maintain compatibility with the 1206 package footprint, surface mount assembly requirements, and circuit protection functionality while accommodating updated product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41206ESDA-TR1 is determined by the following mandatory parameters:

Fixed Requirements (Non-Negotiable):

• Technology: Polymer TVS device
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Number of Circuits: 4
• Base Product Number: 41206 (same product family)
• Functional Category: Transient Voltage Suppressors (TVS)

Flexible Parameters (Application-Dependent):

• Voltage - Clamping: The substitute part may operate at a different clamping voltage provided the circuit design accommodates the alternative voltage rating
• Packaging Format: Original part uses Cut Tape (CT); substitute may use Tape & Reel (TR) format
• Product Status: Active status preferred for ongoing availability
• Compliance Standards: Substitute must maintain RoHS compliance; ROHS3 compliance represents an enhanced standard

The 41206ESDA2-TR2 qualifies as a substitute because it maintains all fixed requirements while offering improved product status and compliance certifications. The clamping voltage difference (60V vs. 35V) requires circuit-level evaluation but does not disqualify the substitute based on physical and functional compatibility.

Engineering Selection Recommendations

Primary Substitute: 41206ESDA2-TR2

The 41206ESDA2-TR2 is the manufacturer-recommended substitute for the obsolete 41206ESDA-TR1. Selection of this substitute is supported by the following engineering factors:

Product Status Justification: The 41206ESDA-TR1 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The 41206ESDA2-TR2 maintains active product status, ensuring reliable procurement for current and future production requirements.

Compliance and Certification: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, representing adherence to the most current environmental and hazardous substance restriction standards. Both parts carry identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications, confirming equivalent regulatory treatment for export and tariff purposes.

Physical and Functional Compatibility: The substitute maintains identical package footprint (1206), mounting type (surface mount), circuit count (4), and technology platform (polymer TVS). These parameters ensure direct compatibility with existing PCB designs and assembly processes without requiring layout modifications or process changes.

Voltage Rating Consideration: The substitute operates at 60V clamping voltage compared to the original 35V rating. This higher voltage rating does not prevent substitution but requires circuit-level verification to confirm that the application can tolerate the alternative voltage characteristic. In protection circuits where the clamping voltage is not a critical design constraint, the higher rating provides equivalent or enhanced protection performance.

Packaging Format: The substitute is supplied in Tape & Reel (TR) format rather than Cut Tape (CT). This format change is compatible with automated assembly processes and does not affect component functionality or PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can the 41206ESDA2-TR2 be used as a direct replacement for the 41206ESDA-TR1 without PCB modifications?

A: Yes, the substitute maintains identical package footprint (1206), mounting type (surface mount), and circuit count (4). No PCB layout changes are required. The component can be placed using the same assembly process and equipment.

Q: What is the significance of the different clamping voltages (35V vs. 60V)?

A: The clamping voltage determines the voltage level at which the TVS device activates to suppress transient overvoltages. The 60V rating of the substitute is higher than the original 35V. In applications where the circuit is designed to tolerate or benefit from a higher clamping threshold, the substitute performs equivalently. In circuits where the 35V threshold is critical to protection strategy, circuit-level analysis is required to confirm compatibility.

Q: Why is the packaging format different (Cut Tape vs. Tape & Reel)?

A: Cut Tape (CT) and Tape & Reel (TR) are supply formats that do not affect component functionality or electrical performance. Tape & Reel format is standard for high-volume automated assembly and offers advantages in handling efficiency. Both formats are compatible with surface mount assembly processes.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: No. ROHS3 compliance represents adherence to the most current environmental standards and is a superset of RoHS compliance. The substitute meets all requirements of the original part and exceeds them with enhanced environmental compliance.

Q: Is the substitute available in inventory?

A: According to the provided data, the 41206ESDA2-TR2 has 31,546 pieces in new original stock, confirming current availability. The original 41206ESDA-TR1, while showing 19,025 pieces in inventory, is classified as obsolete and should not be selected for new designs.

Q: Are there any export or tariff implications when switching to the substitute?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications, confirming equivalent regulatory treatment for export control and tariff purposes.

Q: What is the Moisture Sensitivity Level (MSL) requirement for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage conditions are sufficient; no special desiccant packaging or baking procedures are required prior to assembly.
