TLW-101-06-L-S-LL Equivalent & Substitute Parts

Part Overview

The TLW-101-06-L-S-LL is a single-position rectangular connector header manufactured by Samtec Inc. as part of the Flex Stack TLW series. This through-hole mounted connector features a low-profile design with square male pins, phosphor bronze contacts, and gold plating on mating surfaces. The connector is actively produced and widely used in board-to-board and cable interconnect applications requiring compact form factors and reliable push-pull fastening.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component flexibility within the same electrical and mechanical specifications.

Engineering Selection Recommendations

Both TLW-101-06-L-S-LL and TLW-101-06-G-S are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

Packaging requirements: TLW-101-06-G-S is supplied in bulk packaging, while TLW-101-06-L-S-LL packaging is not specified in available data
Inventory availability: Current stock levels are 718 units for TLW-101-06-L-S-LL and 733 units for TLW-101-06-G-S
Contact finish specification: TLW-101-06-G-S explicitly specifies gold plating on post contacts (Flash thickness), while TLW-101-06-L-S-LL does not provide post contact finish data

Both parts meet ROHS3 compliance and MSL 1 requirements for moisture-sensitive device handling.

Frequently Asked Questions (FAQ)

Q: Are TLW-101-06-L-S-LL and TLW-101-06-G-S mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including contact length (0.105" mating, 0.300" overall), insulation height (0.060"), and single-position, single-row configuration. They are designed for the same board-to-board or cable interconnect applications.

Q: What is the difference between these two part numbers?

A: The primary documented difference is packaging. TLW-101-06-G-S is supplied in bulk packaging. Additionally, TLW-101-06-G-S explicitly specifies gold plating on post contacts with flash thickness, while the TLW-101-06-L-S-LL post contact finish is not specified in available data.

Q: Can I use TLW-101-06-G-S as a direct replacement for TLW-101-06-L-S-LL?

A: Yes. Both parts are electrically and mechanically equivalent with identical current ratings (5.2A per Contact), operating temperature range (-55°C ~ 125°C), and contact materials (Phosphor Bronze). Both are ROHS3 compliant and MSL 1 rated.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are active products from Samtec Inc. with identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).

Q: What is the current rating for these connectors?

A: Both connectors are rated for 5.2A per contact at the specified operating temperature range of -55°C ~ 125°C.
