Engineering Selection Recommendations

All listed substitute parts maintain Active product status and comply with UL94 V-0 flammability requirements. Selection between tin-plated and gold-plated contact finishes depends on application requirements for corrosion resistance and contact reliability.

Molex 0022284120 and 0022284123 provide direct functional equivalence with identical 12-position, 2.54mm pitch configuration. The 0022284120 maintains tin plating matching the TSW-112-08-T-S, while 0022284123 offers gold plating for enhanced contact durability. Both are ROHS3 compliant with higher inventory availability.

Amphenol ICC BERGSTIK® II series (68000, 68001, 68002 variants) offer extended operating temperature ranges (-65°C ~ 125°C or -65°C ~ 130°C) compared to the TSW-112-08-T-S (-55°C ~ 105°C). These parts maintain phosphor bronze contact material and UL94 V-0 rating. Contact length variations across the BERGSTIK® II series accommodate different PCB stack-up requirements while preserving mating pitch and position count.

Tin-plated variants (68000-412HLF, 68001-412HLF, 68002-412HLF) provide cost-effective alternatives with standard contact finish. Gold-plated variants (68000-112HLF, 68000-212HLF, 68001-112HLF, 68001-212HLF, 68002-212HLF) offer enhanced reliability for applications requiring superior contact performance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the TSW-112-08-T-S with a Molex 0022284120?

A: Yes. Both connectors share identical pitch (2.54mm), position count (12), contact type (male pin), mounting method (through hole), and termination (solder). The Molex part maintains tin plating on mating contacts. Minor differences in contact length and insulation material do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference between tin-plated and gold-plated contact finishes?

A: Tin plating provides standard contact finish suitable for general applications. Gold plating offers enhanced corrosion resistance and improved contact reliability in demanding environments. Selection depends on application requirements for contact durability and environmental exposure.

Q: Are the Amphenol ICC BERGSTIK® II parts (68000, 68001, 68002 series) compatible with the TSW-112-08-T-S?

A: Yes. All BERGSTIK® II variants maintain the required 2.54mm pitch, 12-position configuration, male pin contact type, through-hole mounting, and solder termination. The primary differences are extended operating temperature ranges and variations in contact post length. These differences do not affect mating compatibility.

Q: What is the significance of contact length variations across substitute parts?

A: Contact length variations (post length and overall contact length) accommodate different PCB thicknesses and stack-up configurations. The mating contact length remains consistent across all substitutes at 0.230" (5.84mm), ensuring proper mating interface. Post length differences affect how deeply the connector penetrates the PCB.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. The TSW-112-08-T-S is ROHS3 compliant. All listed Molex substitutes are ROHS3 compliant. All Amphenol ICC BERGSTIK® II substitutes are RoHS compliant. Compliance status is maintained across all alternatives.

Q: Can I use a substitute part with an extended operating temperature range in place of the TSW-112-08-T-S?

A: Yes. The Amphenol ICC BERGSTIK® II series operates at -65°C ~ 125°C or -65°C ~ 130°C, which encompasses the TSW-112-08-T-S operating range of -55°C ~ 105°C. Extended temperature capability does not create incompatibility; it provides additional margin for demanding applications.

Q: What packaging formats are available for substitute parts?

A: The TSW-112-08-T-S is supplied in Bag packaging. Molex alternatives are available in Bulk packaging. Amphenol ICC BERGSTIK® II parts are supplied in Bag packaging. Packaging format does not affect connector functionality or compatibility.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary across manufacturers and part variants. Molex 0022284123 (gold-plated) offers the highest inventory at 2769 pieces. Amphenol ICC 68002-412HLF (tin-plated, extended temperature) provides 2842 pieces. Availability should be evaluated against project timeline requirements.
