Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLW-102-05-S-S are qualified based on the following critical parameters that must remain constant:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 2
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 5.2A per Contact
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variations in contact finish specifications (mating and post), contact finish thickness, operating temperature range, and material flammability rating do not preclude substitution when the core electrical and mechanical interface parameters are identical. The substitute parts identified below maintain full compatibility with the TLW-102-05-S-S in applications where these core parameters are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the TLW-102-05-S-S. Selection among these equivalents should be based on the following considerations:

TLW-102-05-F-S operates within a reduced temperature range (-55°C ~ 105°C) compared to the main part. This part is suitable for applications where the upper operating temperature does not exceed 105°C.

TLW-102-05-G-S and MTLW-102-05-G-S-105 both support the full operating temperature range (-55°C ~ 125°C) matching the main part specification. MTLW-102-05-G-S-105 includes UL94 V-0 material flammability rating, providing additional compliance documentation for applications requiring flame-resistance certification.

MTLW-102-05-L-S-105 also supports the full operating temperature range and includes UL94 V-0 flammability rating. This part differs in post contact finish specification (Tin instead of Gold).

All parts share identical electrical interface parameters, mechanical dimensions, and core material specifications, confirming functional interchangeability within their respective temperature and certification constraints.

Frequently Asked Questions (FAQ)

Q: Can TLW-102-05-F-S be used as a direct replacement for TLW-102-05-S-S?

A: TLW-102-05-F-S is functionally equivalent for applications operating within -55°C to 105°C. If your application requires operation above 105°C up to 125°C, this part is not suitable. All other electrical and mechanical parameters are identical.

Q: What is the difference between TLW and MTLW series parts?

A: Both series maintain identical connector type, contact configuration, pitch, and current rating. MTLW series parts include UL94 V-0 material flammability rating, providing additional compliance documentation. The base mechanical and electrical interfaces remain unchanged.

Q: Are contact finish variations significant for substitution?

A: Contact finish variations (Gold vs. Tin on the post) do not affect the mating interface compatibility. Both finishes provide adequate conductivity and corrosion resistance for the specified current rating. Selection should be based on application-specific requirements for post-solder reliability and environmental exposure.

Q: What inventory considerations apply when selecting a substitute?

A: TLW-102-05-G-S offers the highest inventory availability (2486 units), followed by TLW-102-05-F-S (1070 units) and MTLW-102-05-L-S-105 (1052 units). Inventory levels may influence lead time and supply chain planning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the regulatory and handling requirements of the TLW-102-05-S-S.
