TC33X Overview

What changes between part numbers, and what to check before you lock the BOM — Passive Components.

TC33X is a Bourns order-code family — not a single orderable MPN. This page lists 14 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.

Source Manufacturer: Bourns Inc. | Source: Winsource Other listed variants describe: TRIMMER 10K OHM 0.1W J LEAD TOP; TRIMMER 100 OHM 0.1W J LEAD TOP.

Suffix examples in this family: 2-104E, 2-501E, 1-103E, 2-101E, 2-102E, 2-103E, 2-105E, 2-201E. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.

Example MPNs: TC33X-2-104E, TC33X-2-501E, TC33X-1-103E, TC33X-2-101E, TC33X-2-102E, TC33X-2-103E.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
14 distinct suffix patternsExamples: 2-104E, 2-501E, 1-103E, 2-101E, 2-102E (+9 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Passive Components — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

Ordering Code Differences

How suffixes on TC33X map to package, grade, and reel options.

TC33X uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.

Suffixes seen here: 2-104E, 2-501E, 1-103E, 2-101E, 2-102E, 2-103E, 2-105E, 2-201E, 2-202E, 2-203E (+4 more).

Full MPN examples: TC33X-2-104E, TC33X-2-501E, TC33X-1-103E, TC33X-2-101E, TC33X-2-102E.

Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.

How to Choose the Right TC33X Passive Components

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For TC33X, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "TC33X" — include the full suffix (e.g. 2-104E, 2-501E, 1-103E). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the TC33X product family.

Is TC33X a single part I can order, or a family prefix?

TC33X is a base / family code from Bourns. You order a full MPN such as TC33X-2-104E, TC33X-2-501E, TC33X-1-103E. The variant table lists 14 orderable lines with different suffixes.

What do the suffix letters on TC33X part numbers mean?

Listed suffix fragments include: 2-104E, 2-501E, 1-103E, 2-101E, 2-102E, 2-103E. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Bourns datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of TC33X variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on TC33X?

Full manufacturer MPN (not just TC33X), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
