MPN Structure

Samtec MPNs follow a consistent hyphen-delimited structure:

[SERIES]-[PINS]-[PITCH]-[MOUNT]-[OPTIONS]...[-TR]
   |       |      |       |        |          |
   |       |      |       |        |          └── Optional: TR for tape & reel
   |       |      |       |        └── Configuration options (S/D, DV, A, K, etc.)
   |       |      |       └── Profile/mounting (L=low, S=standard, etc.)
   |       |      └── Pitch in mm (e.g., 02.5 = 2.5mm)
   |       └── Pin count (e.g., 110 = 110 pins)
   └── Series prefix (LSHM, SEAM, HSEC8, QSH, QTH, TFM, TSM, SSW, TSW)

│    │   │    │ │  │ │ │ └── TR = Tape & Reel
│    │   │    │ │  │ │ └── K = Keying/polarization
│    │   │    │ │  │ └── S = Surface mount option
│    │   │    │ │  └── A = Alignment option
│    │   │    │ └── DV = Dual row vertical
│    │   │    └── L = Low profile

Pattern Matching

// Each series follows SERIES-PINS-PITCH-OPTIONS format
"^LSHM-[0-9]+-.*"     // High-Speed Micro Headers
"^SEAM-[0-9]+-.*"     // Card Edge
"^HSEC8-[0-9]+-.*"    // High-Speed Edge Card
"^QSH-[0-9]+-.*"      // High-Speed Terminal Socket
"^QTH-[0-9]+-.*"      // High-Speed Terminal Header
"^TFM-[0-9]+-.*"      // Terminal Strip Female
"^TSM-[0-9]+-.*"      // Tiger Eye Terminal Strip
"^SSW-[0-9]+-.*"      // Through-Hole Socket Strip
"^TSW-[0-9]+-.*"      // Through-Hole Terminal Strip

Series Extraction

// Series is the first hyphen-delimited field
// LSHM-110-02.5-L-DV -> LSHM
// TSW-110-01-L-S -> TSW

for (String series : SERIES_FAMILIES.keySet()) {
    if (upperMpn.startsWith(series + "-")) {
        return series;
    }
}

Pin Count Extraction

// Pin count is the second hyphen-delimited field
// LSHM-110-02.5-L-DV -> 110

String[] parts = mpn.split("-");
if (parts.length >= 2) {
    return Integer.parseInt(parts[1]);
}

Pitch Extraction

// Pitch is the third hyphen-delimited field
// LSHM-110-02.5-L-DV -> "02.5"
// But actual pitch may differ from this code

// Use series default pitch for accurate value
String series = extractSeries(mpn);
return SERIES_DEFAULT_PITCH.get(series);

Package Code Extraction

// Package code is everything after pins and pitch
// LSHM-110-02.5-L-DV-A-S-K-TR -> L-DV-A-S-K-TR

String[] parts = mpn.split("-");
if (parts.length >= 4) {
    StringBuilder pkgCode = new StringBuilder();
    for (int i = 3; i < parts.length; i++) {
        if (pkgCode.length() > 0) pkgCode.append("-");
        pkgCode.append(parts[i]);
    }
    return pkgCode.toString();
}

Replacement Compatibility

Same Series Compatibility

For connectors to be interchangeable:

1. Same series (e.g., both LSHM)
2. Same pin count (must match exactly)
3. Compatible mounting type (SMT vs THT)

Mating Pairs

Mounting Type by Series

High-Speed Capability

High-speed rated series:

• LSHM
• HSEC8
• QSH
• QTH

Standard series (not high-speed rated):

• SEAM
• TFM
• TSM
• SSW
• TSW

Learnings & Edge Cases

• Hyphen-delimited format: Unlike IC manufacturers, Samtec uses hyphens to separate all MPN fields
• Pitch code vs actual pitch: The pitch field in MPN may be a code (01, 02.5) rather than actual mm value
• Component type includes IC: Handler registers both CONNECTOR and IC types for pattern matching flexibility
• Pin count in second field: Always extract from second hyphen-delimited field
• Series determines most specs: Series alone determines pitch, mounting type, and current rating
• Mating connector pairs: QSH mates with QTH, SSW mates with TSW, TFM mates with TSM
• TR suffix for packaging: -TR at end indicates tape and reel packaging, strip for extraction
