Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-07-S-D is determined by the following critical parameters:

Primary Matching Criteria:

  • Pitch - Mating: 0.100" (2.54mm)
  • Contact Type: Male Pin
  • Mounting Type: Through Hole
  • Termination: Solder
  • Connector Type: Header

Secondary Compatibility Factors:

  • Number of Positions and Row Configuration
  • Row Spacing - Mating: 0.100" (2.54mm)
  • Contact Finish specifications
  • Operating Temperature Range
  • Insulation Material and Flammability Rating
  • RoHS and regulatory compliance status

The identified substitute part 4-103186-0 (TE Connectivity AMP Connectors) shares the fundamental pitch, contact type, and mounting characteristics. However, this substitute differs in position count (80 vs. 24), product status (Obsolete vs. Active), and compliance certifications, requiring careful evaluation for specific application requirements.

Engineering Selection Recommendations

TSW-112-07-S-D (Primary Selection): The TSW-112-07-S-D remains the preferred choice for new designs and applications requiring active production support. This part is ROHS3 compliant, currently in active production status, and maintains a wider operating temperature range (-55°C to 125°C). The part is suitable for applications demanding regulatory compliance with modern environmental standards.

4-103186-0 (Substitute Consideration): The 4-103186-0 is classified as obsolete and RoHS non-compliant, making it unsuitable for new designs or applications subject to environmental regulations. This substitute shares fundamental electrical and mechanical compatibility (pitch, contact type, mounting method) but differs significantly in position count (80 vs. 24 positions) and compliance status. Use of this substitute is limited to legacy system maintenance or applications where the higher position count and breakaway feature provide functional advantage despite compliance limitations.

Frequently Asked Questions (FAQ)

Q: Can the 4-103186-0 directly replace the TSW-112-07-S-D in new designs?

A: No. The 4-103186-0 is obsolete and RoHS non-compliant. New designs must use the TSW-112-07-S-D or identify an active, compliant alternative. The 4-103186-0 differs in position count (80 vs. 24), making direct mechanical substitution problematic.

Q: What are the critical parameters for substitution compatibility?

A: Substitutes must maintain 0.100" (2.54mm) pitch spacing, male pin contact type, through-hole mounting, and solder termination. Row spacing and number of rows should match the application requirements. Contact finish specifications and operating temperature ranges must be evaluated against application constraints.

Q: Why does the 4-103186-0 have 80 positions instead of 24?

A: The 4-103186-0 is a different connector model within the TE Connectivity product line, designed for higher-density applications. Position count is a fundamental design parameter and cannot be modified through substitution.

Q: Are there compliance concerns with the 4-103186-0?

A: Yes. The 4-103186-0 is RoHS non-compliant and obsolete. Applications subject to RoHS directives or requiring active manufacturer support cannot use this part.

Q: What is the difference between the contact finish specifications?

A: The TSW-112-07-S-D uses tin post finish, while the 4-103186-0 uses tin-lead post finish. Tin-lead finishes are restricted in RoHS-compliant applications. Contact material also differs: phosphor bronze versus copper alloy.

Q: Can the operating temperature ranges be considered equivalent?

A: No. The TSW-112-07-S-D operates from -55°C to 125°C, while the 4-103186-0 operates from -65°C to 105°C. The TSW-112-07-S-D provides superior high-temperature performance, while the 4-103186-0 extends lower-temperature capability. Application requirements determine which range is appropriate.
