Molex Manufacturer Handler Skill

Overview

MolexHandler manages Molex connectors including Micro-Fit, Mini-Fit Jr., PicoBlade, KK 254, PicoClasp, Nano-Fit, and Micro-Lock Plus series.

Supported Component Types

CONNECTOR
CONNECTOR_MOLEX

MPN Patterns

Micro-Fit 3.0 Series (3.0mm pitch, 5A)

Prefix	Description
43045-xxxx	Micro-Fit 3.0 headers
43046-xxxx	Micro-Fit 3.0 receptacles

Mini-Fit Jr. Series (4.2mm pitch, 9A)

Prefix	Description
39281-xxxx	Mini-Fit Jr. headers
39282-xxxx	Mini-Fit Jr. receptacles

PicoBlade Series (1.25mm pitch, 1A)

Prefix	Description
53261-xxxx	PicoBlade headers
53262-xxxx	PicoBlade receptacles

KK 254 Series (2.54mm pitch, 3A)

Prefix	Description
22057-xxxx	KK 254 headers
22058-xxxx	KK 254 receptacles

Additional Series

Prefix	Description	Pitch	Current
51021-xxxx	PicoClasp	1.0mm	1A
51047-xxxx	Nano-Fit	2.5mm	3.5A
87832-xxxx	Micro-Lock Plus	2.0mm	3A

MPN Structure

Format:

XXXXX-YYYY

XXXXX = 5-digit series code
YYYY = 4-digit package code (first 2 digits = pin count, last 2 = mounting)

Package Code Extraction

Returns 4-digit code after dash (e.g., "43045-0802" returns "0802").

Series Extraction

Returns 5-digit series code (e.g., "43045-0802" returns "43045").

Helper Methods

```
getPitch(mpn)
```
- Returns pitch in mm
```
getMountingType(mpn)
```
- Returns THT, SMT, or Other
```
getOrientation(mpn)
```
- Returns Vertical, Right Angle, or Right Angle Reversed
```
getRatedCurrent(mpn)
```
- Returns rated current in Amps
```
isKeyed(mpn)
```
- Returns true for most series (false for KK series)
```
getGender(mpn)
```
- Returns Male (odd series) or Female (even series)
```
hasLatchingMechanism(mpn)
```
- Returns true for most series

Mounting Type Codes

Ends with 01, 02 = Through-Hole
Ends with 10, 11 = Surface Mount

Replacement Logic

Must be from same connector family
Must have same pin count
Must have compatible mounting type (THT/THT or SMT/SMT)

Test Patterns

When testing MolexHandler:

Use documentation tests for
```
matches()
```
behavior
Use assertions for
```
extractPackageCode()
```
,
```
extractSeries()
```
, null handling
Instantiate directly:
```
new MolexHandler()
```
