TSW-136-07-S-D Equivalent & Substitute Parts

Part Overview

The TSW-136-07-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical header features 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is currently in active production status with gold-plated mating contacts and tin-plated posts, suitable for operating temperatures from -55°C to 125°C.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-07-S-D is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm)
Connector Type: Header with male pins
Mounting Type: Through Hole
Termination: Solder
Row Spacing - Mating: 0.100" (2.54mm)
Contact Finish - Mating: Gold
Insulation Material: PBT or equivalent thermoplastic
Material Flammability Rating: UL94 V-0

The substitute part 4-103186-0 (TE Connectivity AMP Connectors) shares the same mating pitch, connector type, mounting method, and termination approach. However, this part differs in position count (80 vs. 72), insulation height, contact finish thickness, operating temperature range, and compliance status, which must be evaluated for specific application requirements.

Engineering Selection Recommendations

The TSW-136-07-S-D is the preferred choice for new designs due to its active production status and ROHS3 compliance. The part meets current regulatory requirements and offers extended operating temperature range (-55°C to 125°C) compared to the substitute.

The 4-103186-0 substitute is classified as obsolete and does not meet RoHS compliance standards. This part should only be considered for legacy system maintenance or repair applications where the original specification is mandatory. The substitute exhibits differences in contact post length (0.120" vs. 0.100"), insulation height (0.090" vs. 0.100"), contact finish thickness (15.0µin vs. 30.0µin), and operating temperature ceiling (105°C vs. 125°C). The higher position count (80 vs. 72) requires careful PCB layout verification to ensure mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 4-103186-0 be used as a direct replacement for the TSW-136-07-S-D?

A: Direct replacement is not recommended. While both connectors share the same 0.100" (2.54mm) mating pitch and 2-row configuration, the 4-103186-0 has 80 positions versus 72 positions in the TSW-136-07-S-D. The substitute also has different contact post length, insulation height, and operating temperature specifications. PCB layout and application requirements must be evaluated before substitution.

Q: What are the compliance differences between these parts?

A: The TSW-136-07-S-D is ROHS3 compliant and actively produced. The 4-103186-0 is RoHS non-compliant and obsolete. For applications subject to RoHS regulations, the TSW-136-07-S-D is the only acceptable choice.

Q: How do the operating temperature ranges differ?

A: The TSW-136-07-S-D operates from -55°C to 125°C, while the 4-103186-0 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the TSW-136-07-S-D.

Q: Are the contact finishes compatible?

A: Both parts feature gold-plated mating contacts. However, the TSW-136-07-S-D has 30.0µin (0.76µm) gold thickness compared to 15.0µin (0.38µm) on the 4-103186-0. The TSW-136-07-S-D also uses tin-plated posts, while the 4-103186-0 uses tin-lead posts.

Q: What is the significance of the position count difference?

A: The TSW-136-07-S-D has 72 positions while the 4-103186-0 has 80 positions. This difference affects PCB footprint, connector length, and circuit routing. Substitution requires verification that the additional 8 positions do not create mechanical interference or routing conflicts on the target PCB.

Q: Can the 4-103186-0 be used in legacy system repairs?

A: The 4-103186-0 may be used for maintenance of existing systems originally designed with this connector, provided that the application does not require RoHS compliance and the operating temperature does not exceed 105°C. For new designs or systems requiring regulatory compliance, the TSW-136-07-S-D is mandatory.
