EVM-ASGA00B16 Equivalent & Substitute Parts

Part Overview

The EVM-ASGA00B16 is a 1 MOhm, 0.3W surface mount trimmer potentiometer manufactured by Panasonic Electronic Components. This cermet-based, top-adjustment component features a single turn and is designed for surface mount applications. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign applications where this component is specified in legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVM-ASGA00B16 is determined by the following critical parameters:

• Resistance Value: 1 MOhms (exact match required)
• Power Rating: Minimum 0.3W (equal or greater acceptable)
• Tolerance: ±25% (standard for trimmer potentiometers)
• Temperature Coefficient: ±200ppm/°C or better stability acceptable
• Number of Turns: 1 turn (single adjustment range)
• Adjustment Type: Top Adjustment (user interface requirement)
• Resistive Material: Cermet (performance and stability characteristics)
• Moisture Sensitivity: MSL 1 (Unlimited) or equivalent

The 3306P-1-105 from Bourns Inc. meets these core electrical specifications. However, this substitute differs in mounting technology: it is a through-hole component with PC pin termination, whereas the original is surface mount. This difference requires circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-105 provides electrical equivalence for the obsolete EVM-ASGA00B16 in terms of resistance, tolerance, adjustment type, and resistive material. Both components are rated MSL 1 (Unlimited) and are REACH Unaffected.

Critical Considerations:

The 3306P-1-105 has a lower power rating (0.2W versus 0.3W). Applications requiring the full 0.3W dissipation capacity must evaluate whether 0.2W is sufficient for the intended circuit operation.

The 3306P-1-105 exhibits a slightly higher temperature coefficient (±250ppm/°C versus ±200ppm/°C). In temperature-sensitive applications, this difference may affect long-term stability and calibration drift.

The fundamental difference is mounting technology: the substitute is through-hole with PC pin termination, while the original is surface mount. This requires complete circuit board redesign and assembly process modification. Direct mechanical substitution on existing surface mount boards is not possible.

The 3306P-1-105 is currently in active production status with substantial inventory availability (12,414 pcs), whereas the EVM-ASGA00B16 is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-105 be used as a direct replacement on existing circuit boards designed for the EVM-ASGA00B16?

A: No. The EVM-ASGA00B16 is a surface mount component, while the 3306P-1-105 is a through-hole component with PC pin termination. Direct substitution requires circuit board redesign and assembly process modification.

Q: Does the lower power rating of the 3306P-1-105 (0.2W) affect compatibility?

A: The substitute has a lower power rating than the original (0.2W versus 0.3W). Compatibility depends on the actual power dissipation requirements of your application. If the circuit dissipates more than 0.2W through the potentiometer, the substitute is not suitable.

Q: Are there differences in temperature stability between these components?

A: Yes. The 3306P-1-105 has a temperature coefficient of ±250ppm/°C compared to the original's ±200ppm/°C. In applications requiring high temperature stability or precision calibration, this difference may be significant.

Q: What is the significance of the MSL 1 rating for both components?

A: MSL 1 (Unlimited) indicates that both components have unlimited shelf life and do not require special moisture control during storage or handling. This is the least restrictive moisture sensitivity level.

Q: Are both components RoHS and REACH compliant?

A: The EVM-ASGA00B16 is REACH Unaffected. The 3306P-1-105 is ROHS3 Compliant and REACH Unaffected. Both meet current environmental compliance standards.

Q: What is the base product number for the 3306P-1-105?

A: The base product number is 3306P, which is the Bourns Trimpot® 3306 series. The 3306P-1-105 is a specific variant within this series with 1 MOhm resistance and top adjustment configuration.
