EVM-2TSX80B12 Equivalent & Substitute Parts

Part Overview

The EVM-2TSX80B12 is a 100 Ohm, 0.15W surface mount trimmer potentiometer manufactured by Panasonic Electronic Components. This cermet-based trimmer features top adjustment with a single turn and is designed for precision resistance tuning applications. The product is currently obsolete, making identification of compatible substitute components essential for ongoing maintenance, repair, and new design implementations where this specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVM-2TSX80B12 is determined by the following critical parameters:

• Resistance Value: 100 Ohms (exact match required)
• Adjustment Type: Top Adjustment (functional requirement for accessibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Resistive Material: Cermet (performance and stability characteristics)
• Number of Turns: 1 Turn (adjustment range and resolution)
• Termination Style: Surface Mount compatible (soldering compatibility)

The substitute part 3312J-1-101E meets these core substitution criteria. While the power rating differs (0.1W versus 0.15W), tolerance and temperature coefficient specifications remain within acceptable operational parameters for equivalent functional performance in the intended application context.

Engineering Selection Recommendations

The 3312J-1-101E from Bourns Inc. serves as a direct functional substitute for the obsolete EVM-2TSX80B12. Selection of this substitute is supported by the following factors:

• Product Status: The 3312J-1-101E maintains active production status, ensuring availability and supply chain continuity.
• Compliance: The Bourns component carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing.
• Electrical Equivalence: Both components share identical resistance values, adjustment types, and resistive materials. The 3312J-1-101E provides improved tolerance (±20% versus ±25%) and superior temperature stability (±100ppm/°C versus ±250ppm/°C).
• Mechanical Compatibility: Both components are surface mount trimmers with single-turn top adjustment, ensuring functional interchangeability in circuit applications.

The lower power rating of the 3312J-1-101E (0.1W versus 0.15W) requires verification that application power dissipation does not exceed the substitute component's thermal limits.

Frequently Asked Questions (FAQ)

Q: Can the 3312J-1-101E directly replace the EVM-2TSX80B12 on existing PCBs?

A: The 3312J-1-101E is functionally equivalent for resistance tuning applications. However, the termination style differs (J Lead versus standard Surface Mount). Physical footprint compatibility must be verified against the original PCB layout before implementation.

Q: What is the significance of the power rating difference between these components?

A: The EVM-2TSX80B12 is rated at 0.15W while the 3312J-1-101E is rated at 0.1W. The substitute component can be used if the application's power dissipation remains below 0.1W. Applications requiring the full 0.15W rating require alternative sourcing.

Q: Does the improved tolerance of the 3312J-1-101E affect circuit performance?

A: The 3312J-1-101E provides tighter tolerance (±20% versus ±25%), which represents improved precision. This does not negatively impact circuits designed for the original component and may enhance overall circuit stability.

Q: Are there compliance differences between these components?

A: The 3312J-1-101E carries ROHS3 compliance certification. The original EVM-2TSX80B12 compliance status is not specified in available documentation. For applications requiring specific regulatory compliance, the Bourns component meets current environmental standards.

Q: What packaging format is the 3312J-1-101E supplied in?

A: The 3312J-1-101E is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations.
