MPN Structure

Sullins uses letter-prefix series with encoded specifications:

SBH/SFH Series (Box Headers, FFC/FPC)

SBH11-PBPC-D10-ST-BK
 |  |   |   |   |  |
 |  |   |   |   |  +-- Color (BK=Black, GY=Gray)
 |  |   |   |   +-- Mount (ST=Straight, RA=Right Angle)
 |  |   |   +-- Pin count (D10 = Dual 10 = 20 total pins)
 |  |   +-- Contact type (PBPC=Phosphor Bronze, Tin)
 |  +-- Series variant (11, 21, etc.)
 +-- Series prefix (SBH=Box Header, SFH=FFC/FPC)

PPPC/PRPC/NPPN Series (Headers)

PRPC040SAAN-RC
 |   | ||| |  |
 |   | ||| |  +-- Mount suffix (RC=Through-Hole, SC=SMT)
 |   | ||| +-- Plating (N=Tin, etc.)
 |   | ||+-- Contact options
 |   | |+-- Contact type
 |   | +-- Row count (1=Single, 2=Dual)
 |   +-- Pin count (040 = 40 pins)
 +-- Series (PRPC=Male, PPPC=Female, NPPN=Pin)

Feature Value
Type Flat flex cable connector
Pitch 1.27mm
Rated Current 1.0A
Row Config Dual row

Pattern: ^SFH[0-9]+-[A-Z]+-D[0-9]+.*

Pin Count Extraction

SBH/SFH Series

Pin count follows "D" prefix and is doubled for dual row:

java
// SBH11-PBPC-D10-ST-BK -> 10 * 2 = 20 pins
Matcher m = Pattern.compile("D([0-9]+)").matcher(mpn);
if (m.find()) {
    return Integer.parseInt(m.group(1)) * 2;  // Dual row
}

PPPC/PRPC/NPPN Series

Pin count is first 2-3 digits after series prefix:

java
// PRPC040SAAN-RC -> 40 pins
// PPPC081LFBN-RC -> 8 pins
Pattern.compile("(PPPC|PRPC|NPPN)([0-9]+)").matcher(mpn);
return Integer.parseInt(m.group(2));

Mounting Type Codes

Suffix Codes

Code Mounting Type
-RC Through-Hole
-SC SMT
ST Straight (Through-Hole)
RA Right Angle (Through-Hole)
SM Surface Mount

Detection Example

java
String upper = mpn.toUpperCase();
if (upper.contains("-RC")) return "Through-Hole";
if (upper.contains("-SC")) return "SMT";
if (upper.contains("-RA")) return "Through-Hole Right Angle";
if (upper.contains("-ST")) return "Through-Hole Straight";

Gender Detection

Series Gender
PPPC Female (Socket)
PRPC Male (Pin)
NPPN Male (Pin)
SBH Male (Shrouded)
SFH Male (Shrouded)

Row Count Detection

SBH/SFH

Always dual row (indicated by "D" prefix before pin count).

PPPC/PRPC/NPPN

Digit after pin count indicates rows:

java
// PRPC040SAAN-RC
//        ^ Row digit (S=Single, but position encoding varies)
// Check the digit after the pin count digits

// More reliable: Parse with regex
Pattern.compile("(PPPC|PRPC|NPPN)([0-9]+)([0-9])").matcher(mpn);
int rows = Integer.parseInt(m.group(3));  // 1=single, 2=dual

Contact Plating

Code Plating Type
GN, G/ Gold
SN, T/ Tin
LF Lead-Free Tin

Handler Implementation Notes

Series Extraction

java
// Extract known series prefixes
if (upperMpn.startsWith("SBH")) return "SBH";
if (upperMpn.startsWith("PPPC")) return "PPPC";
if (upperMpn.startsWith("PRPC")) return "PRPC";
if (upperMpn.startsWith("NPPN")) return "NPPN";
if (upperMpn.startsWith("SFH")) return "SFH";

// Generic extraction (3-4 letter prefix before digits)
Pattern.compile("^([A-Z]{3,4})[0-9]").matcher(mpn);

Package Code Extraction

java
// SBH/SFH: Mount type is in dash-separated field
// Example: SBH11-PBPC-D10-ST-BK -> ST = Straight

// PPPC/PRPC/NPPN: Mount type is suffix
// Example: PRPC040SAAN-RC -> RC = Through-Hole

// Look for standard suffix codes
if (upper.contains("-RC")) return "Through-Hole";
if (upper.contains("-SC")) return "SMT";

Replacement Compatibility

java
// Compatible if:
// 1. Same series
// 2. Same pin count
// 3. Compatible mounting type (both THT or both SMT)

String series1 = extractSeries(mpn1);
String series2 = extractSeries(mpn2);
if (!series1.equals(series2)) return false;

int pins1 = extractPinCount(mpn1);
int pins2 = extractPinCount(mpn2);
if (pins1 != pins2) return false;

return areCompatibleMountingTypes(mpn1, mpn2);

Common Part Numbers

MPN Description
PRPC040SAAN-RC 40-pin male header, single row, through-hole
PPPC081LFBN-RC 8-pin female header, lead-free, through-hole
SBH11-PBPC-D10-ST-BK 20-pin box header (10x2), straight, black
NPPN101BFCN-RC 10-pin header, through-hole

  • No manufacturer-specific ComponentType enum entries

Learnings & Edge Cases

  • Row count encoding: For PPPC/PRPC/NPPN, the digit after the pin count indicates row count (1=single, 2=dual).
  • SBH/SFH always dual: Box headers and FFC connectors are always dual row. Pin count in MPN is per-row, multiply by 2.
  • Pitch by series: SBH/PPPC/PRPC/NPPN are 2.54mm pitch. SFH is 1.27mm pitch (fine pitch FFC).
  • Right angle detection: Look for "RA" in package code OR in the dash-separated fields. Beware: "stRAight" contains "RA".
  • Color codes: BK=Black, GY=Gray, WH=White, BL=Blue appear at the end of SBH/SFH MPNs.
  • Dual connector type: Handler registers both CONNECTOR and IC types.
