EVM-MSGA01B13 Equivalent & Substitute Parts

Part Overview

The EVM-MSGA01B13 is a 1 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Panasonic Electronic Components. This cermet-based component features PC pin termination, top adjustment, and a square form factor (5.80mm x 5.80mm). The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVM-MSGA01B13 is determined by strict equivalence across the following core parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W
• Number of turns: 1 turn
• Adjustment mechanism: Top adjustment
• Resistive element: Cermet composition
• Mounting configuration: Through-hole PC pins
• Functional application: Trimmer potentiometer

The Bourns 3329H-1-102 satisfies all mandatory electrical and mechanical criteria for direct substitution. While dimensional differences exist (round 6.35mm diameter versus square 5.80mm), both components maintain identical electrical specifications and PC pin termination, permitting functional interchange in circuit applications where form factor constraints do not apply.

Parameter Comparison

Engineering Selection Recommendations

The 3329H-1-102 (Bourns Trimpot® 3329 series) is the qualified substitute for the obsolete EVM-MSGA01B13. Selection is based on:

• Electrical equivalence: Identical resistance, power rating, and turn count
• Functional compatibility: Matching adjustment mechanism and termination style
• Active product status: The Bourns component remains in active production, ensuring procurement availability
• Improved tolerance: The 3329H-1-102 provides ±10% tolerance versus ±20%, offering superior initial accuracy
• Specified temperature coefficient: ±100ppm/°C provides defined thermal performance

Physical form factor differences (square versus round) require verification against PCB layout constraints. Where space permits, the round geometry of the 3329H-1-102 presents no functional impediment to substitution.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-102 directly replace the EVM-MSGA01B13 in existing designs?

A: Yes, provided PCB layout accommodates the round 6.35mm diameter form factor. Electrical specifications, PC pin termination, and adjustment mechanism are identical.

Q: What is the significance of the tolerance difference (±20% versus ±10%)?

A: The EVM-MSGA01B13 permits ±20% initial resistance variation, while the 3329H-1-102 maintains ±10%. The Bourns component delivers tighter initial accuracy, beneficial for applications requiring precise trimmer calibration.

Q: Why is the EVM-MSGA01B13 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 3329H-1-102 remains actively manufactured, providing long-term supply continuity.

Q: Are both components RoHS non-compliant?

A: Yes. Both the EVM-MSGA01B13 and 3329H-1-102 are classified as RoHS non-compliant. Design compliance requirements must be evaluated independently.

Q: What packaging is available for the substitute part?

A: The 3329H-1-102 is supplied in tube packaging. Verify packaging requirements against procurement specifications.
