Ersa Selective Soldering Nozzle Part Number Guide

Finding the correct Ersa selective soldering nozzle part number is essential for ordering compatible replacement parts quickly and accurately. This guide explains how Ersa nozzle part numbers work, how to decode nozzle specifications, and where to find the information you need.

Key Takeaways

**Part numbers uniquely identify each nozzle** — including ID/AD, height, and base type

**B14.1/B22 is the most common base type** — with 90+ nozzle configurations

**B16.1/B36 uses different part number formats** — some with alphanumeric codes

**Legacy designations (B14.1, B16.1) are interchangeable** — with current B22, B36

**Search by dimensions if part number is unknown** — ID/AD + height + base type

Understanding Ersa Nozzle Part Numbers

Ersa nozzle part numbers (also called reference numbers) are numeric identifiers assigned to each specific nozzle configuration. For example:

**114613** — S Nozzle 6.0/10.0, H=47, B14.1/B22

**114609** — S Nozzle 3.0/6.0, H=47, B14.1/B22

**118615** — S Nozzle 8.0/12.0, H=47, B14.1/B22

Each part number uniquely identifies a nozzle with specific:

**ID/AD dimensions** — The inner and outer diameter at the nozzle tip

**Height (H value)** — The total height from the solder pot surface

**Base type** — The solder pot connection interface (B14.1/B22 or B16.1/B36)

How to Find Your Nozzle Part Number

You can find your nozzle part number through:

1. **Machine documentation** — Check your Ersa machine manual or the nozzle selection guide provided with the equipment

2. **Original nozzle marking** — Some nozzles have the part number etched or printed on the body

3. **SMT line records** — Your production line setup documentation should list all nozzle configurations

4. **Online search** — Search by ID/AD size, height, and base type to find the matching part number

Legacy vs. Current Designations

Ersa has updated some nozzle base type designations over the years:

**B14.1 → B22** — The same physical base type, updated naming convention

**B16.1 → B36** — The same physical base type, updated naming convention

When searching for a nozzle, include both legacy and current designations to ensure you find all compatible options.

Ordering Compatible Replacement Nozzles

When ordering aftermarket compatible replacement nozzles:

Provide the exact reference part number

Verify the ID/AD dimensions, height, and base type match your requirement

Specify the quantity needed

Confirm that the nozzle is an aftermarket compatible part, an aftermarket compatible replacement product

If you cannot find your exact part number, send your old nozzle dimensions, a photo, or an engineering drawing for custom matching. See our [B14.1 vs B22 Guide](/technical-guides/b14-1-vs-b22-selective-soldering-nozzles) and [B16.1 vs B36 Guide](/technical-guides/b16-1-vs-b36-selective-soldering-nozzles) for more details.
