Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68734-572H are qualified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Number of Positions: 72
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull

Secondary Compatibility Factors:

• Style: Board to Board or Board to Board/Cable
• Shrouding: Unshrouded
• Material Flammability Rating: UL94 V-0

All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact finish, contact material, insulation material, and overall contact length are secondary parameters that do not prevent functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Compliance Considerations:

The 68734-572H is RoHS non-compliant. All identified substitute parts are RoHS compliant (ROHS3 or RoHS Compliant status), making them suitable for applications requiring regulatory compliance with RoHS directives.

Product Status:

All substitute parts maintain Active product status, ensuring continued availability and manufacturer support equivalent to the original part.

Flammability Rating:

The 68734-572H, 3-826632-6, 3-826925-6, and TSW-136-24-T-D all carry UL94 V-0 material flammability ratings. The Samtec BBD series parts do not specify a flammability rating in the provided data.

Temperature Operating Range:

The 68734-572H does not specify an operating temperature range. Substitute parts provide defined temperature ranges: TE Connectivity parts operate from -65°C to 105°C, Samtec BBD series from -55°C to 125°C, and Samtec TSW series from -55°C to 105°C. Selection should account for application-specific thermal requirements.

Contact Finish and Material:

The 68734-572H features gold or gold GXT™ finish on square contacts with phosphor bronze material. TE Connectivity 3-826632-6 provides gold finish on square contacts with brass material. TE Connectivity 3-826925-6 offers tin finish on square contacts with copper alloy material. Samtec BBD series provides either gold or tin finish on circular contacts. Samtec TSW-136-24-T-D provides tin finish on square contacts with phosphor bronze material. Contact finish selection depends on application corrosion resistance and mating surface compatibility requirements.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the 68734-572H?

A: The critical parameters are: 72 positions, 2 rows, 0.100" (2.54mm) pitch spacing, male pin contact type, through-hole mounting, solder termination, push-pull fastening, and unshrouded design. All identified substitute parts meet these specifications.

Q: Can I use a substitute part with a different contact shape (circular vs. square)?

A: Contact shape differences exist between the 68734-572H (square contacts) and some Samtec BBD series substitutes (circular contacts). While both shapes function in standard board-to-board applications, mating surface compatibility and contact pressure characteristics may differ. Application-specific validation is necessary when transitioning between contact geometries.

Q: What is the difference between the TE Connectivity 3-826632-6 and 3-826925-6?

A: Both parts are 72-position, 2-row headers with identical pitch and mounting specifications. The primary differences are contact finish (gold vs. tin) and contact material (brass vs. copper alloy). Both are RoHS compliant and operate from -65°C to 105°C with 5A current rating.

Q: Are there packaging differences between substitute parts?

A: Yes. The 68734-572H, 3-826632-6, 3-826925-6, and TSW-136-24-T-D are supplied in bulk packaging. The Samtec BBD series (BBD-136-G-A, BBD-136-G-B, BBD-136-T-B) are supplied in tube packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Does the 68734-572H RoHS non-compliance affect substitution decisions?

A: The 68734-572H is RoHS non-compliant while all substitute parts are RoHS compliant. For applications subject to RoHS regulations or customer requirements, substitute parts provide regulatory compliance. For legacy or non-regulated applications, the original part remains functionally equivalent.

Q: What is the difference in overall contact length between the main part and substitutes?

A: The 68734-572H has an overall contact length of 0.615" (15.62mm). TE Connectivity substitutes provide 0.500" (12.70mm), Samtec BBD series provide 0.460" (11.68mm) or 0.585" (14.86mm) depending on variant, and Samtec TSW provides 0.480" (12.19mm). Contact length affects mating depth and board spacing compatibility. Application PCB design must accommodate the selected substitute's contact geometry.

Q: Can I use TSW-136-24-T-D in applications requiring board-to-board connections only?

A: The TSW-136-24-T-D is rated for both board-to-board and cable applications. It functions in board-to-board configurations and is therefore suitable for such applications. The additional cable compatibility capability does not restrict its use in board-to-board designs.
