EVM-ASGA00B22 Equivalent & Substitute Parts

Part Overview

The EVM-ASGA00B22 is a 200 Ohm, 0.3W surface mount trimmer potentiometer manufactured by Panasonic Electronic Components. This cermet-based, single-turn top adjustment component is designed for precision resistance tuning in compact surface mount applications. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign projects where this component is specified in legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVM-ASGA00B22 is determined by the following critical parameters that must remain constant or compatible:

• Resistance Value: 200 Ohms (exact match required)
• Resistive Material: Cermet (maintains performance characteristics)
• Number of Turns: 1 (single-turn adjustment)
• Adjustment Type: Top Adjustment (functional interface requirement)
• Tolerance: ±25% (acceptable performance band)

The substitute part 3306P-1-201 matches all core electrical parameters. However, this substitute introduces a significant change in mounting technology: it transitions from surface mount to through-hole PC pin termination. This represents a mechanical and assembly-level difference that requires board redesign or adapter solutions for direct substitution in existing surface mount layouts.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-201 provides electrical equivalence to the EVM-ASGA00B22 across all core resistance and adjustment parameters. The substitute is manufactured by Bourns Inc., a recognized supplier of precision trimmer potentiometers, and maintains ROHS3 compliance and REACH unaffected status consistent with the original component.

Two critical differences require evaluation:

Power Rating Reduction: The substitute operates at 0.2W versus the original 0.3W. Applications requiring the full 0.3W dissipation capacity must confirm that 0.2W is sufficient for the intended circuit operation.

Temperature Coefficient Increase: The substitute exhibits ±250ppm/°C versus ±200ppm/°C for the original. Applications with stringent temperature stability requirements must assess whether this 50ppm/°C increase is acceptable for the operating environment.

Mounting Architecture Change: The transition from surface mount to through-hole PC pin termination requires PCB redesign. This is not a direct drop-in replacement for existing surface mount layouts without mechanical adaptation.

The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-201 be used as a direct replacement in a surface mount assembly?

A: No. The 3306P-1-201 is a through-hole component with PC pin termination, while the EVM-ASGA00B22 is surface mount. Direct substitution requires PCB redesign or mechanical adapter solutions.

Q: Are the electrical specifications compatible between these two parts?

A: The resistance value, tolerance, number of turns, and adjustment type are identical. The temperature coefficient is slightly higher (±250ppm/°C vs ±200ppm/°C), and the power rating is lower (0.2W vs 0.3W). Verify that these differences are acceptable for your application.

Q: What is the significance of the Cermet resistive material in both parts?

A: Cermet (ceramic-metal composite) provides stable resistance characteristics across temperature ranges and is standard for precision trimmer potentiometers. Both parts use this material, ensuring consistent performance behavior.

Q: Why is the original part obsolete?

A: The EVM-ASGA00B22 is listed as obsolete by Panasonic Electronic Components. The 3306P-1-201 represents an active alternative from Bourns Inc. for applications requiring 200 Ohm, single-turn cermet trimmer potentiometers.

Q: Are there compliance differences between the two parts?

A: Both parts are REACH unaffected and classified under ECCN EAR99. The substitute is ROHS3 compliant. Compliance status is equivalent for regulatory purposes.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. Both parts carry this rating, meaning standard storage conditions are acceptable without special humidity controls.
