Package Code Extraction

• SJ series: Returns suffix letter(s) (N, NR, NC, etc.)
• PJ series: Returns suffix letter(s) (A, AH, B, etc.)
• CMI/CMS: Returns last letter (T for terminal, P for PCB)
• AMT series: Returns suffix after dash (V for vertical)

Series Extraction

MPN	Extracted Series
SJ1-3523N	SJ1
PJ-002A	PJ
CMI-1295-85T	CMI
CMS-15118-78P	CMS
AMT102-V	AMT102
ACZ11BR1E	ACZ11

Helper Methods

• isAudioConnector(mpn)

  - Returns true for SJ series

• isPowerConnector(mpn)

  - Returns true for PJ series

• isBuzzer(mpn)

  - Returns true for CMI, CPE, CPT series

• isSpeaker(mpn)

  - Returns true for CMS series

• isEncoder(mpn)

  - Returns true for AMT, ACZ series

• getProductFamily(mpn)

  - Returns family description

• getMountingType(mpn)

  - Returns mounting type (Vertical, SMT, etc.)

• getTransducerSizeMm(mpn)

  - Returns diameter in mm for buzzers/speakers

• getImpedanceOhms(mpn)

  - Returns impedance in ohms for buzzers/speakers

Replacement Logic

• Audio jacks: Same connector number (middle section) required
• Encoders: Same series including resolution number required
• Transducers: Same size AND impedance required
• Cross-series replacement not allowed

Test Patterns

When testing CUIHandler:

1. Use assertions for

   matches()

   with CONNECTOR, AUDIO_JACK, SPEAKER, BUZZER, ENCODER types
2. Use assertions for

   extractPackageCode()

   ,

   extractSeries()

3. Test helper methods for classification
4. Instantiate directly:

   new CUIHandler()

Real-World MPN Examples

MPN	Type	Description
SJ1-3523N	Audio Jack	3.5mm stereo jack, vertical PCB
SJ1-3525N	Audio Jack	3.5mm jack with switch
PJ-002A	Power Jack	DC barrel jack, 2.0mm ID
CMS-15118-78P	Speaker	15mm speaker, 8 ohm
CMI-1295-85T	Buzzer	12mm magnetic buzzer
AMT102-V	Encoder	Modular incremental encoder

Learnings & Quirks

MPN Format Patterns

• SJ series uses format: SJx-xxxxY where x=series, xxxx=type code, Y=mount suffix
• CMI/CMS series encode size in first 2 digits of first number group
• AMT series embeds resolution in series number (AMT102 = 102 PPR base)
• ACZ series numbers indicate mechanical size

Package Code Meanings

Code	Meaning
N	Vertical/PCB mount
NR	Vertical with nut/retention
A	Surface mount
AH	Surface mount horizontal
T	Terminal type
P	PCB mount
V	Vertical
H	Horizontal
