Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RJ-6W201 are qualified based on the following critical parameters that must match or remain within acceptable tolerances:

• Resistance value: 200 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

All identified substitute parts meet these electrical and mechanical criteria. Physical dimensions vary within acceptable ranges for through-hole mounting applications. Packaging format and compliance certifications differ but do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts (RJ-6W201, 25PR200LF, 3329H-1-201, and 82PR200LF) are functionally equivalent for circuit applications requiring 200 Ohm, 0.5W cermet trimmer potentiometers with top adjustment and PC pin termination.

For applications requiring ROHS3 compliance and REACH unaffected status, the RJ-6W201 and 82PR200LF are suitable selections. The 25PR200LF provides RoHS compliance with REACH unaffected status. The 3329H-1-201 carries RoHS non-compliant and REACH affected designations and should be selected only when regulatory requirements permit.

Physical dimension variations exist among the substitute parts. The RJ-6W201 features a 7.00mm round body, while the 3329H-1-201 and 82PR200LF use 6.35mm round bodies, and the 25PR200LF uses a 6.86mm square body. These dimensional differences do not affect electrical performance but may impact PCB layout considerations for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 25PR200LF replace the RJ-6W201 in a circuit design?

A: Yes. Both parts share identical electrical specifications (200 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, PC pins). The primary difference is physical form factor: the 25PR200LF has a square body (6.86mm) versus the RJ-6W201's round body (7.00mm). PCB layout compatibility should be verified.

Q: What is the difference between the 3329H-1-201 and the other substitutes?

A: The 3329H-1-201 is electrically identical to all other substitutes but carries RoHS non-compliant and REACH affected certifications. It should be used only in applications where these regulatory restrictions do not apply. Its 6.35mm round body is smaller than the RJ-6W201.

Q: Are the 82PR200LF and RJ-6W201 interchangeable?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and share all critical electrical parameters. The 82PR200LF has a 6.35mm round body compared to the RJ-6W201's 7.00mm round body. Both use bulk packaging.

Q: Does packaging format affect part selection?

A: Packaging format (bulk versus tube) does not affect electrical or mechanical performance. Selection depends on procurement quantity requirements and inventory management practices.

Q: Can I use the 25PR200LF if my design requires ROHS3 compliance?

A: The 25PR200LF is RoHS compliant but not specifically ROHS3 certified. For applications requiring explicit ROHS3 compliance, the RJ-6W201 or 82PR200LF are the appropriate selections.
