Substitute Part Grouping Explanation

Substitute parts for the LTMM-117-02-L-D-RA are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (34)
• Number of rows (2)
• Pitch - mating (0.079" / 2.00mm)
• Row spacing - mating (0.079" / 2.00mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Style (Board to Board or Board to Board/Cable)

The SBH21-NBPN-D17-RA-BK from Sullins Connector Solutions meets all critical substitution parameters and is classified as a direct equivalent for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the LTMM-117-02-L-D-RA and SBH21-NBPN-D17-RA-BK are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on the following factors:

The LTMM-117-02-L-D-RA supports an extended lower operating temperature limit of -55°C, making it suitable for applications requiring operation below -40°C. The SBH21-NBPN-D17-RA-BK operates from -40°C to 105°C and supports both board-to-board and cable applications, providing greater application flexibility.

Both parts feature identical mating pitch, row spacing, position count, and shrouding specifications. The SBH21-NBPN-D17-RA-BK is available in higher inventory (1758 units) compared to the LTMM-117-02-L-D-RA (795 units).

Frequently Asked Questions (FAQ)

Q: Can the SBH21-NBPN-D17-RA-BK replace the LTMM-117-02-L-D-RA in all applications?

A: The SBH21-NBPN-D17-RA-BK is compatible for applications operating between -40°C and 105°C. Applications requiring operation below -40°C must use the LTMM-117-02-L-D-RA due to its extended lower temperature rating of -55°C.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), position count (34), row count (2), mounting type (through-hole right-angle), and shrouding (4-wall). These parameters ensure mechanical interchangeability in board-level applications.

Q: Are there differences in contact materials?

A: The LTMM-117-02-L-D-RA uses phosphor bronze contacts, while the SBH21-NBPN-D17-RA-BK uses brass contacts. Both feature gold mating contact finish. The contact material difference does not affect electrical performance for standard signal and power applications within the specified operating parameters.

Q: What packaging differences exist?

A: The LTMM-117-02-L-D-RA is supplied in tube packaging, while the SBH21-NBPN-D17-RA-BK is supplied in tray packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes, both the LTMM-117-02-L-D-RA and SBH21-NBPN-D17-RA-BK are ROHS3 compliant with EAR99 ECCN classification.
