TLW-105-06-L-S Equivalent & Substitute Parts

Part Overview

The TLW-105-06-L-S is an active Samtec Inc. rectangular connector header from the Flex Stack TLW series. This through-hole connector features 5 positions at 0.100" (2.54mm) pitch with unshrouded, male pin contacts rated for 5.2A per contact. The connector uses phosphor bronze contacts with gold mating finish and liquid crystal polymer insulation, designed for board-to-board or cable applications with push-pull fastening. Substitute parts are identified to support inventory management, supply chain continuity, and design flexibility while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the TLW-105-06-L-S are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical pitch (0.100" / 2.54mm), position count (5), contact type (male pin), current rating (5.2A per contact), operating temperature range (-55°C ~ 125°C), and contact material (phosphor bronze).

Mechanical Compatibility: All parts share the same connector type (header), mounting method (through hole), termination (solder), fastening type (push-pull), contact shape (square), insulation material (LCP), and overall contact length (0.300" / 7.62mm).

Regulatory Compliance: All parts are ROHS3 compliant, active products from Samtec Inc. within the Flex Stack TLW series, and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Substitution Basis: Differences in contact finish specifications (mating and post finishes) and finish thickness do not affect functional interchangeability for standard board-to-board or cable connection applications.

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and identical electrical and mechanical specifications. Selection between TLW-105-06-L-S, TLW-105-06-F-S, and TLW-105-06-G-S is determined by post-finish requirements and inventory availability:

TLW-105-06-L-S: Primary specification with unspecified post finish. Use when post finish is not a design constraint.

TLW-105-06-F-S: Tin post finish with 959 units in stock. Select when tin post termination is required for soldering compatibility.

TLW-105-06-G-S: Gold post finish (flash) with highest inventory (1300 units). Select when gold post finish is specified for enhanced corrosion resistance or when maximum availability is required.

Frequently Asked Questions (FAQ)

Q: Are TLW-105-06-L-S, TLW-105-06-F-S, and TLW-105-06-G-S electrically interchangeable?

A: Yes. All three parts maintain identical pitch (0.100" / 2.54mm), position count (5), contact type (male pin), current rating (5.2A per contact), and operating temperature range (-55°C ~ 125°C). Electrical performance is equivalent across all three variants.

Q: What is the difference between these substitute parts?

A: The primary difference is the contact post finish. TLW-105-06-L-S has an unspecified post finish, TLW-105-06-F-S features tin post finish, and TLW-105-06-G-S features gold post finish (flash). All maintain gold mating finish. These differences do not affect functional interchangeability in standard applications.

Q: Can I substitute TLW-105-06-F-S for TLW-105-06-L-S in my design?

A: Yes, provided your design does not have specific post-finish requirements. Both parts are mechanically and electrically compatible with identical connector geometry, contact ratings, and operating specifications.

Q: Which part should I select for new designs?

A: Selection depends on post-finish requirements and supply chain considerations. Verify your PCB assembly process compatibility with the post finish specification. All three parts are active products with full ROHS3 compliance suitable for production use.

Q: Are there any MSL (Moisture Sensitivity Level) differences?

A: No. All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.
