EVM-ASGA00B25 Equivalent & Substitute Parts

Part Overview

The EVM-ASGA00B25 is a 200 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 configuration. 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 in existing designs.

Key Parameters

Substitute Part Grouping Explanation

The 3306P-1-204 (Bourns Inc.) qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• Resistance value: 200 kOhms
• Tolerance: ±25%
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Power rating: 0.2W (substitute) vs. 0.3W (main part)
• Temperature coefficient: ±250ppm/°C (substitute) vs. ±200ppm/°C (main part)
• Mounting type: Through Hole PC Pins (substitute) vs. Surface Mount (main part)
• Product status: Active (substitute) vs. Obsolete (main part)

The 3306P-1-204 maintains electrical equivalence in resistance, tolerance, and adjustment characteristics. The through-hole mounting configuration represents a design change that requires PCB layout modification. The reduced power rating (0.2W vs. 0.3W) and slightly higher temperature coefficient must be evaluated against application thermal and stability requirements.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-204 is available as an active product with ROHS3 compliance, addressing supply continuity concerns associated with the obsolete EVM-ASGA00B25. Electrical parameters remain compatible for applications where the 0.2W power rating is sufficient and the ±250ppm/°C temperature coefficient meets stability requirements.

Implementation of the 3306P-1-204 requires PCB redesign to accommodate through-hole mounting in place of surface mount configuration. This substitution is suitable for applications where design modification is feasible and thermal dissipation requirements do not exceed the reduced power rating.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-204 directly replace the EVM-ASGA00B25 without PCB modification?

A: No. The EVM-ASGA00B25 uses surface mount termination while the 3306P-1-204 uses through-hole PC pins. PCB layout modification is required.

Q: Are the electrical characteristics compatible?

A: The resistance value (200 kOhms), tolerance (±25%), and adjustment type (top adjustment, 1 turn) are identical. The temperature coefficient differs by 50ppm/°C (±250ppm/°C vs. ±200ppm/°C), which may be acceptable depending on application stability requirements.

Q: What is the impact of the lower power rating on the 3306P-1-204?

A: The substitute part is rated at 0.2W compared to 0.3W for the main part. Applications must operate within the 0.2W thermal limit. Verify that circuit conditions do not exceed this power dissipation threshold.

Q: Does the 3306P-1-204 meet current compliance standards?

A: Yes. The 3306P-1-204 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The EVM-ASGA00B25 status is not specified for these certifications.

Q: What is the availability status of each part?

A: The EVM-ASGA00B25 is obsolete with 705 units in stock. The 3306P-1-204 is an active product with 1947 units in stock, providing superior long-term supply assurance.
