Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLW-104-01-S-S-RA is determined by strict equivalence across the following critical parameters:

• Manufacturer: Samtec Inc.
• Series: Flex Stack, TLW
• Number of Positions: 4
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Contact Length - Mating: 0.230" (5.84mm)
• Contact Length - Post: 0.120" (3.05mm)
• Insulation Height: 0.098" (2.50mm)
• Current Rating: 5.2A per Contact
• Operating Temperature: -55°C ~ 125°C
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part TLW-104-01-G-S-RA meets all critical parameters and is therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

Both TLW-104-01-S-S-RA and TLW-104-01-G-S-RA are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating equivalent environmental handling and storage requirements.

The parts are functionally equivalent for all standard applications requiring a 4-position, 0.100" pitch through-hole right-angle header with 5.2A per contact current capacity and -55°C to 125°C operating temperature range.

Selection between these parts should be based on inventory availability and supply chain requirements, as both meet identical performance and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Are TLW-104-01-S-S-RA and TLW-104-01-G-S-RA electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including contact material (Phosphor Bronze), current rating (5.2A per contact), operating temperature range (-55°C ~ 125°C), and contact geometry (0.230" mating length, 0.120" post length).

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts have identical mechanical specifications including 4 positions, 0.100" (2.54mm) pitch, through-hole right-angle mounting, 0.098" (2.50mm) insulation height, and square contact shape.

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

A: The primary difference is in contact finish specification documentation. TLW-104-01-G-S-RA provides explicit contact finish thickness values (10.0µin mating, Flash post), while TLW-104-01-S-S-RA does not specify these values in the provided data. Both parts have gold plating on mating contacts.

Q: Are both parts RoHS compliant?

A: Yes. Both TLW-104-01-S-S-RA and TLW-104-01-G-S-RA are ROHS3 compliant.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C, suitable for industrial and automotive applications within this temperature range.

Q: What is the current capacity per contact?

A: Both parts are rated for 5.2A per contact, supporting applications requiring moderate current distribution across multiple contacts.
