EVM-ASGA00B24 Equivalent & Substitute Parts

Part Overview

The EVM-ASGA00B24 is a 20 kOhms surface mount trimmer potentiometer manufactured by Panasonic Electronic Components. This cermet-based trimmer features 0.3W power rating, ±25% tolerance, and top adjustment capability with a single turn. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EVM-ASGA00B24 are identified based on the following critical parameters that must align for functional equivalence:

• Resistance Value: 20 kOhms (exact match required)
• Resistive Material: Cermet (maintains performance characteristics)
• Number of Turns: 1 (single-turn adjustment)
• Adjustment Type: Top Adjustment (operational interface requirement)
• Tolerance: ±25% (acceptable variance specification)

The 3306P-1-203 substitute shares these core electrical characteristics. However, this substitute differs in mounting technology (through-hole PC pins versus surface mount termination) and power rating (0.2W versus 0.3W). These differences require circuit-level evaluation to determine suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-203 is an active product from Bourns Inc. and represents a viable substitute for the obsolete EVM-ASGA00B24 based on matching electrical specifications (20 kOhms, ±25% tolerance, cermet material, single-turn top adjustment).

Selection of this substitute requires evaluation of the following factors:

• Mounting Compatibility: The substitute uses through-hole PC pin termination, whereas the original uses surface mount termination. PCB layout and assembly process modifications are necessary.
• Power Dissipation: The substitute is rated at 0.2W compared to the original 0.3W. Circuit analysis must confirm that maximum power dissipation does not exceed 0.2W under all operating conditions.
• Temperature Performance: The substitute exhibits ±250ppm/°C temperature coefficient versus ±200ppm/°C for the original. This 50ppm/°C difference may impact temperature-dependent circuit performance.
• Compliance Status: The 3306P-1-203 is RoHS3 compliant and active in production, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-203 be used as a direct replacement for the EVM-ASGA00B24?

A: Electrical substitution is possible due to matching resistance, tolerance, material, and adjustment characteristics. However, mounting type differs fundamentally (through-hole versus surface mount), requiring PCB redesign and assembly process changes.

Q: What is the impact of the 0.1W power rating difference?

A: The substitute is rated 0.1W lower (0.2W versus 0.3W). Applications must operate within the 0.2W maximum dissipation limit. If the original design dissipates more than 0.2W, the substitute is not suitable without circuit modification.

Q: How does the temperature coefficient difference affect performance?

A: The substitute has a ±250ppm/°C coefficient compared to ±200ppm/°C for the original. In temperature-sensitive applications, this 50ppm/°C increase may introduce measurable drift. Thermal analysis of the specific circuit is required.

Q: Is the 3306P-1-203 available for long-term supply?

A: Yes. The 3306P-1-203 is classified as active product status and is RoHS3 compliant, indicating ongoing manufacturing and availability.

Q: What are the physical dimension differences?

A: The substitute is specified as rectangular with 0.319" x 0.268" face dimensions (8.10mm x 6.80mm). The original EVM-ASGA00B24 dimensions are not provided in the specification data. Physical verification against PCB layout is required before implementation.
