M63P204KB40 Equivalent & Substitute Parts

Part Overview

The M63P204KB40 is a 200 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Vishay Spectrol. This cermet-based component features side adjustment capability and PC pin termination, designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

The 82PR200KLF qualifies as a substitute for the M63P204KB40 based on the following matching electrical parameters:

• Resistance value: 200 kOhms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1 (identical)
• Resistive material: Cermet (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The primary difference between these parts is the adjustment type (side adjustment versus top adjustment) and physical package geometry. Both components maintain electrical equivalence within the specified tolerance and performance parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the M63P204KB40 and 82PR200KLF are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• PCB layout constraints: The M63P204KB40 occupies a square footprint (10.03mm x 10.03mm), while the 82PR200KLF uses a smaller round footprint (6.35mm diameter). Space-constrained designs may favor the 82PR200KLF.
• Adjustment accessibility: The M63P204KB40 provides side adjustment, while the 82PR200KLF offers top adjustment. Circuit board layout and user interface requirements determine which adjustment orientation is appropriate.
• Inventory availability: Both parts maintain active stock levels (923 pcs and 910 pcs respectively).

Frequently Asked Questions (FAQ)

Q: Can the 82PR200KLF directly replace the M63P204KB40 in existing designs?

A: Electrical substitution is valid due to identical resistance, power rating, tolerance, temperature coefficient, and termination specifications. However, physical layout verification is required due to differences in package geometry (square versus round) and adjustment orientation (side versus top). PCB footprint and mechanical clearance must be confirmed before implementation.

Q: What are the critical parameters for 200 kOhms trimmer potentiometer substitution?

A: Substitution validity requires matching: resistance value (200 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), resistive material (Cermet), mounting type (Through Hole), and termination style (PC Pins). Adjustment type and package geometry are secondary considerations dependent on application-specific requirements.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications. The 82PR200KLF includes REACH Unaffected status documentation.

Q: How do adjustment type differences affect circuit performance?

A: Adjustment type (side versus top) affects mechanical accessibility and PCB layout only. Electrical performance and resistance characteristics remain identical. Selection depends on design requirements for potentiometer access and available board space.
