What’s the Difference Between OEM, Original, and Aftermarket Phone Parts?

Introduction

1. Original and OEM Parts (The Gold Standard)

These are the same parts that were installed in your phone when it left the factory.

• Original parts come directly from the phone’s brand (e.g., Apple, Samsung).

• OEM parts (Original Equipment Manufacturer) are made by the same manufacturer but may be sold through different channels.

Why choose Original parts or OEM?

• ✅ Top-notch quality and perfect fit

• ✅ High compatibility with your device

• ✅ Often preserves your phone’s warranty (especially when installed by an authorized repair provider)
   

Downside: They usually cost more — but you’re paying for peace of mind.

2. Third-Party or Aftermarket Parts (Budget-Friendly, But Be Cautious)

These parts are made by companies not affiliated with your phone’s brand.

• Quality varies. Some are excellent, while others may lead to problems.

• They’re more affordable than OEM parts, which makes them attractive if you’re on a budget.

Things to watch out for:

• ⚠️ Cheaper parts may wear out faster

• ⚠️ May affect touch sensitivity, display brightness, or battery life

• ⚠️ Could void your warranty

If a shop offers you a much lower price, ask: Are these OEM or aftermarket parts?

3. Used or Refurbished Parts (Lowest Cost, But High Risk)

These are parts pulled from old or previously used phones.

• They’re the cheapest option on the market.

• Quality depends heavily on how the part was handled and stored.

Consider this if:

• You’re repairing an older phone and just need it to last a few more months

• You understand the risks (e.g., shorter lifespan, no warranty)

Pro Tip: Ask Your Repair Shop What Parts They Use
Not all repair shops are transparent. Before you approve any iPhone screen replacement or repair, ask:

• “Are these OEM or third-party parts?”

• “Do you offer a warranty for these parts?”

• “What’s the expected lifespan of this replacement?”

And always choose a reputable provider that clearly explains your options. For peace of mind, check out SellUp’s repair network where you can compare providers who use original or high-quality parts and stand behind their work.
