Substitute Part Grouping Explanation

Substitution of the HTSS-105-03-L-D is permissible with parts that maintain identical or compatible specifications across the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (10) and row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole) and termination (Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact shape (Square)
• Flammability compliance (UL94 V-0)
• RoHS3 compliance status

The substitute part SBH11-PBPC-D05-ST-BK from Sullins Connector Solutions satisfies all critical substitution criteria within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSS-105-03-L-D and SBH11-PBPC-D05-ST-BK maintain active product status and full RoHS3 compliance. Both connectors satisfy UL94 V-0 flammability requirements and carry MSL 1 moisture sensitivity ratings.

The primary distinction between these parts is the operating temperature range. The HTSS-105-03-L-D supports -55°C to 125°C operation, while the SBH11-PBPC-D05-ST-BK operates within -40°C to 105°C. Selection between these parts must be based on the specific thermal requirements of the application. For applications requiring extended low-temperature operation below -40°C or sustained operation above 105°C, the HTSS-105-03-L-D is the appropriate choice. For applications within the -40°C to 105°C range, the SBH11-PBPC-D05-ST-BK is functionally equivalent.

Both parts are manufactured to identical mechanical and electrical interface specifications, ensuring mechanical and electrical interchangeability within their respective operating temperature boundaries.

Frequently Asked Questions (FAQ)

Q: Are the HTSS-105-03-L-D and SBH11-PBPC-D05-ST-BK mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (10 in 2 rows), shrouding configuration (4-wall), and contact geometry (square male pins). They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the key difference between these two parts?

A: The primary difference is operating temperature range. The HTSS-105-03-L-D operates from -55°C to 125°C, while the SBH11-PBPC-D05-ST-BK operates from -40°C to 105°C. The HTSS-105-03-L-D also uses Liquid Crystal Polymer (LCP) insulation, while the SBH11-PBPC-D05-ST-BK uses Polybutylene Terephthalate (PBT).

Q: Can I use the SBH11-PBPC-D05-ST-BK in place of the HTSS-105-03-L-D in all applications?

A: The SBH11-PBPC-D05-ST-BK is suitable for applications operating within -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the HTSS-105-03-L-D.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the HTSS-105-03-L-D and SBH11-PBPC-D05-ST-BK are ROHS3 compliant.

Q: What is the packaging difference between these parts?

A: The HTSS-105-03-L-D is supplied in Bulk packaging, while the SBH11-PBPC-D05-ST-BK is supplied in Tray packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both connectors support push-pull fastening?

A: Yes. Both the HTSS-105-03-L-D and SBH11-PBPC-D05-ST-BK feature push-pull fastening mechanisms.

Q: Are the contact finishes equivalent?

A: Both connectors feature gold-plated mating contacts. The HTSS-105-03-L-D has tin-plated posts with 10.0µin (0.25µm) gold thickness on mating surfaces. The SBH11-PBPC-D05-ST-BK has gold-plated posts with flash gold thickness on mating surfaces. Both finishes provide equivalent corrosion resistance and electrical performance for standard applications.
