Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLW-104-05-L-S are identified within the Samtec Flex Stack TLW series based on matching core electrical and mechanical parameters. The substitution criteria are:

• Identical connector type (Header), contact type (Male Pin), and number of positions (4)
• Matching pitch specification (0.100" / 2.54mm)
• Identical mounting method (Through Hole) and termination type (Solder)
• Equivalent current rating (5.2A per Contact)
• Matching operating temperature range (-55°C ~ 125°C)
• Identical insulation material (Liquid Crystal Polymer) and contact material (Phosphor Bronze)
• Equivalent RoHS3 compliance and MSL rating

Variations between the main part and substitutes are limited to contact finish specifications on the mating and post surfaces. These finish variations do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TLW-104-05-L-S, TLW-104-05-G-S, and TLW-104-05-F-S—are active products with ROHS3 compliance and identical core electrical and mechanical specifications. Selection between these parts is determined by contact finish requirements and inventory availability:

TLW-104-05-G-S offers the highest inventory level (26,441 pcs) with gold plating on both mating and post surfaces, providing consistent corrosion resistance across all contact areas.

TLW-104-05-F-S provides tin plating on the post surface with reduced gold thickness on the mating surface (3.00µin), suitable for cost-optimized applications with adequate inventory (1,017 pcs).

TLW-104-05-L-S specifies gold mating finish with post finish not detailed, with moderate inventory availability (704 pcs).

All parts share identical RoHS3 compliance, MSL rating, and functional parameters for board-to-board or cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are TLW-104-05-L-S, TLW-104-05-G-S, and TLW-104-05-F-S electrically interchangeable?

A: Yes. All three parts maintain identical electrical specifications including 4-position configuration, 0.100" (2.54mm) pitch, 5.2A per contact current rating, and -55°C to 125°C operating temperature range. Differences are limited to contact finish specifications.

Q: What is the functional difference between the contact finish variations?

A: Contact finish differences affect corrosion resistance and contact reliability characteristics. TLW-104-05-G-S provides gold plating on both mating and post surfaces. TLW-104-05-F-S uses tin on the post with thinner gold on the mating surface. TLW-104-05-L-S specifies gold on the mating surface with post finish not detailed. These variations do not affect mechanical fit or basic electrical function.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All three parts share identical through-hole mounting specifications, solder termination requirements, and physical dimensions. PCB footprints and assembly processes remain unchanged across all three variants.

Q: Are all three parts RoHS3 compliant?

A: Yes. TLW-104-05-L-S, TLW-104-05-G-S, and TLW-104-05-F-S are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which part should be selected for high-reliability applications?

A: Selection depends on specific environmental and contact reliability requirements. TLW-104-05-G-S with full gold plating on both surfaces provides consistent corrosion resistance. Consult application-specific reliability standards and environmental exposure conditions for final selection.
