Key Parameters

Substitute Part Grouping Explanation

The 4-103240-0-01 manufactured by TE Connectivity AMP Connectors qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Connector Type: Header (with Breakaway capability)
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Basis: The 4-103240-0-01 maintains electrical and mechanical compatibility through identical pitch spacing, contact configuration, and mating interface geometry. Both connectors support the same board-to-board or cable connection topology with equivalent solder termination and push-pull fastening mechanisms.

Parameter Comparison

Engineering Selection Recommendations

The 4-103240-0-01 serves as a functional equivalent for the discontinued TSW-101-26-S-D based on matching electrical and mechanical interface specifications. Both connectors maintain identical pitch spacing, contact configuration, and solder termination geometry required for board-to-board or cable interconnection.

Compliance Considerations:

The TSW-101-26-S-D is ROHS3 compliant, while the 4-103240-0-01 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference. The substitute part features Tin-Lead post finish versus Tin on the main part, which may impact soldering processes and thermal cycling performance in specific applications.

Temperature Operating Range:

The main part operates across -55°C to 125°C, while the substitute operates across -65°C to 105°C. Applications requiring the full upper temperature range of the main part should evaluate thermal performance requirements against the substitute's reduced upper limit.

Physical Dimensions:

Minor variations exist in contact post length (0.126" versus 0.120") and insulation height (0.100" versus 0.090"), resulting in overall contact length differences of 0.016". These dimensional variations are within typical connector tolerance ranges but should be verified against specific PCB layout and mating interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4-103240-0-01 directly replace the TSW-101-26-S-D in existing designs?

A: The 4-103240-0-01 maintains identical pitch spacing (0.100" / 2.54mm), contact configuration (2 positions, 2 rows), and mating interface geometry. Direct mechanical and electrical compatibility is established for board-to-board or cable applications. However, verify compliance requirements, thermal operating range, and PCB layout tolerances against the minor dimensional variations in contact post length and insulation height.

Q: What are the key differences between these connectors?

A: The primary differences are: (1) RoHS compliance status (main part is ROHS3 compliant; substitute is non-compliant), (2) operating temperature upper limit (125°C versus 105°C), (3) contact post finish (Tin versus Tin-Lead), (4) contact material (Phosphor Bronze versus Copper Alloy), and (5) insulation material specification (PBT versus generic Thermoplastic). Mating interface parameters remain identical.

Q: Are there packaging differences between these parts?

A: The TSW-101-26-S-D packaging is not specified in available data. The 4-103240-0-01 is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the current rating for these connectors?

A: The TSW-101-26-S-D current rating is not specified. The 4-103240-0-01 is rated for 3A. Confirm current requirements for your application against the substitute's 3A specification.

Q: How do the contact finishes compare?

A: Both connectors feature gold-plated mating contacts at 30.0µin (0.76µm) thickness. The main part uses Tin post finish, while the substitute uses Tin-Lead post finish. This difference may affect soldering characteristics and thermal cycling performance depending on application requirements.

Q: Are both connectors suitable for high-temperature applications?

A: The TSW-101-26-S-D operates to 125°C, while the 4-103240-0-01 operates to 105°C. For applications requiring sustained operation above 105°C, the main part specification should be maintained. For applications within the 105°C limit, both connectors are suitable.
