Substitute Part Grouping Explanation
Substitution for the MP2-H030-51P1-S-TG30 is determined by the following critical parameters:
- Number of Positions: 30 positions (exact match required for connector interface compatibility)
- Pitch: 0.079" (2.00mm) (determines PCB footprint and mating interface)
- Mounting Type: Through Hole (mechanical installation method)
- Termination: Press-Fit (assembly process compatibility)
- Connector Type: Header, Male Pins (functional role in backplane assembly)
- Material Flammability Rating: UL94 V-0 (safety compliance requirement)
- Operating Temperature Range: Must support -55°C ~ 125°C minimum
Substitute parts are grouped into two categories:
Category 1: Direct 3M MetPak™ MP2 Series Equivalent
- MP2-H030-51P1-S-KR: Active product status, identical electrical and mechanical specifications, RoHS compliant variant
Category 2: Amphenol ICC (FCI) Metral® Series Cross-Substitutes
- Parts with 36 positions (55003 and 59566 series) provide functional alternatives with enhanced specifications but require PCB layout modification due to increased position count
- Parts with 30 positions (10043968 series) provide direct electrical equivalence with higher current rating and active product status

Engineering Selection Recommendations
Primary Substitute: MP2-H030-51P1-S-KR
The MP2-H030-51P1-S-KR is the direct equivalent within the 3M MetPak™ MP2 series. It maintains identical electrical and mechanical specifications to the MP2-H030-51P1-S-TG30 while offering active product status and RoHS compliance. This part is suitable for direct replacement in legacy systems without PCB modification.
Secondary Substitutes: 10043968-5001LF and 10043968-5002LF
The Amphenol ICC (FCI) Metral® 10043968 series provides 30-position headers with identical pitch and row configuration. These parts offer enhanced current rating (3A versus 1.5A) and active product status. The operating temperature range is reduced to -55°C ~ 105°C, which may be acceptable depending on system requirements. These parts are suitable for applications where higher current capacity is beneficial.
Alternative Substitutes: 55003 and 59566 Series (36-Position)
The 55003 and 59566 series provide 36-position headers with shielded construction and high-speed connector styling. These parts require PCB layout modification due to increased position count and are suitable only when additional signal or ground positions are required. The 55003-901003LF offers the highest inventory availability (1605 pcs) among Amphenol alternatives.
Compliance Considerations
The original MP2-H030-51P1-S-TG30 is RoHS non-compliant. For new designs or systems requiring RoHS compliance, MP2-H030-51P1-S-KR or Amphenol alternatives (55003-901003LF, 59566-1002LF) are recommended.
Frequently Asked Questions (FAQ)
Q: Can MP2-H030-51P1-S-KR be used as a direct replacement for MP2-H030-51P1-S-TG30?
A: Yes. The MP2-H030-51P1-S-KR is electrically and mechanically identical to the original part. It shares the same 30-position count, 0.079" pitch, through-hole mounting, and press-fit termination. The primary difference is active product status and RoHS compliance.
Q: What is the difference between the 30-position and 36-position Amphenol alternatives?
A: The 30-position Amphenol parts (10043968 series) provide direct electrical equivalence without PCB modification. The 36-position parts (55003 and 59566 series) include additional signal and ground positions, requiring PCB layout changes. Selection depends on whether additional positions are needed in the application.
Q: Are there temperature limitations with Amphenol substitutes?
A: Yes. Amphenol alternatives operate to -55°C ~ 105°C, while the original 3M part operates to -55°C ~ 125°C. If the application requires operation above 105°C, the MP2-H030-51P1-S-KR is the appropriate choice.
Q: What is the current rating difference between substitutes?
A: The original MP2-H030-51P1-S-TG30 and MP2-H030-51P1-S-KR are rated at 1.5A per contact. The Amphenol 10043968 series is rated at 3A per contact, providing higher current capacity. The 55003 and 59566 series are rated at 1A per contact.
Q: Does packaging type affect substitution compatibility?
A: Packaging (tube, bulk, or tray) affects handling and storage but does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly requirements.
Q: Are the 55003-301002LF and 55003-301003LF interchangeable?
A: Both parts are 36-position headers with identical electrical and mechanical specifications. The difference is contact finish thickness (51.2µin versus 50.0µin), which does not affect functional compatibility. They are interchangeable for most applications.
