84WR200LF Surface Mount Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The 84WR200LF is a 200 Ohm, 0.25W surface mount trimmer potentiometer manufactured by TT Electronics/BI. This cermet-based component features 12-turn top adjustment and is housed in a rectangular package measuring 0.250" x 0.170" (6.35mm x 4.32mm). The part is RoHS compliant and carries an active product status. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, packaging formats, or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (200 Ohms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), resistive material (cermet), and mounting type (surface mount). Packaging format (tube or tape & reel) and termination style (top adjustment vs. gull wing) are secondary considerations that do not affect electrical functionality but may impact assembly processes and compliance requirements.

The substitute parts identified are:

• 3269W-1-201 (Bourns Inc., Trimpot® 3269 - Sealed series)
• 3269W-1-201GLF (Bourns Inc., Trimpot® 3269 - Sealed series)
• 3269W-1-201LF (Bourns Inc., Trimpot® 3269 - Sealed series)
• 3224X-1-201E (Bourns Inc., Trimpot® 3224 - Sealed series, manufacturer recommended)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Electrical Equivalents):

The 3269W-1-201GLF and 3269W-1-201LF are direct electrical equivalents with identical face dimensions (0.250" x 0.170"). Both carry ROHS3 compliance and active product status. The 3269W-1-201GLF is packaged in tape & reel format suitable for automated assembly, while the 3269W-1-201LF is tube-packaged. Both maintain MSL 2 rating.

The 3269W-1-201 (tube-packaged) is electrically equivalent but carries RoHS non-compliant status and should be selected only when RoHS compliance is not a design requirement.

Manufacturer-Recommended Substitute:

The 3224X-1-201E is designated as the manufacturer-recommended substitute. It maintains all electrical parameters and achieves ROHS3 compliance with MSL 1 rating (superior moisture sensitivity performance). However, the face dimension is reduced to 0.189" x 0.138" (4.80mm x 4.60mm), requiring PCB layout verification before implementation.

Compliance Considerations:

For applications requiring RoHS compliance, select from 3269W-1-201GLF, 3269W-1-201LF, or 3224X-1-201E. The 3224X-1-201E offers superior MSL rating (MSL 1 vs. MSL 2) for moisture-sensitive environments.

Frequently Asked Questions (FAQ)

Q: Can the 3224X-1-201E be used as a direct replacement for the 84WR200LF?

A: The 3224X-1-201E is electrically equivalent and functionally compatible. However, the reduced face dimension (0.189" x 0.138" vs. 0.250" x 0.170") requires PCB footprint verification. Physical board space constraints may prevent direct substitution without layout modification.

Q: What is the difference between the 3269W-1-201, 3269W-1-201GLF, and 3269W-1-201LF?

A: These three parts are electrically identical. The primary differences are packaging format and compliance status. The 3269W-1-201GLF uses tape & reel packaging for automated assembly. The 3269W-1-201LF and 3269W-1-201 use tube packaging. The 3269W-1-201 is RoHS non-compliant, while both the GLF and LF variants are ROHS3 compliant.

Q: Why does the 84WR200LF show RoHS compliant status while the 3269W-1-201 shows RoHS non-compliant?

A: RoHS compliance status is manufacturer-specific and may reflect different production batches, material sourcing, or certification timelines. Verify current compliance documentation with the component supplier for the specific lot required.

Q: What does MSL 1 vs. MSL 2 mean for component selection?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. MSL 1 (unlimited shelf life) provides greater flexibility in storage and handling conditions. MSL 2 (1-year shelf life) requires controlled storage environments and shorter time windows between package opening and assembly. The 3224X-1-201E offers MSL 1 performance.

Q: Are the gull wing terminations of the Bourns substitutes compatible with the original PCB footprint?

A: Termination style differences (surface mount vs. gull wing) may affect solder joint geometry and PCB pad design. Verify footprint compatibility with your PCB design specifications before implementation. Gull wing terminations typically require modified pad layouts compared to standard surface mount terminations.
