Engineering Selection Recommendations

Molex KK254 Series (0022284120, 0022284123): These parts are ROHS3 compliant and active products. The 0022284120 variant with tin finish provides direct functional equivalence to the TSW-112-08-T-S. The 0022284123 variant offers gold plating for enhanced corrosion resistance in demanding environments. Both are available in high inventory quantities.

Amphenol ICC BERGSTIK® II Series (68000-112HLF through 68002-412HLF): All BERGSTIK® II variants are RoHS compliant and active products with 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 feature phosphor bronze contacts matching the main part material. Selection between variants depends on contact finish requirement (tin or gold) and post length specifications. The 68000 series features 0.095" post length, 68001 series features 0.120" post length, and 68002 series features 0.150" post length.

Contact Finish Selection:

Tin finish variants (0022284120, 68000-412HLF, 68001-412HLF, 68002-412HLF) match the TSW-112-08-T-S finish specification
Gold finish variants (0022284123, 68000-112HLF, 68000-212HLF, 68001-112HLF, 68001-212HLF, 68002-212HLF) provide enhanced durability for high-cycle mating applications

Compliance Status: All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. RoHS compliance is confirmed for all alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Molex KK254 part for the TSW-112-08-T-S? A: Yes. The Molex 0022284120 (tin finish) and 0022284123 (gold finish) are functionally equivalent. Both match the critical parameters: 12-position, 2.54mm pitch, through-hole solder termination, push-pull fastening, and square contact geometry. Verify contact finish requirements for your application.

Q: What is the difference between tin and gold plated variants? A: Tin-plated contacts (TSW-112-08-T-S, 0022284120, 68000-412HLF, 68001-412HLF, 68002-412HLF) provide standard corrosion resistance. Gold-plated contacts (0022284123, 68000-112HLF, 68000-212HLF, 68001-112HLF, 68001-212HLF, 68002-212HLF) offer superior durability in high-cycle mating or harsh environments. Gold finish thickness varies between 15.0µin and 30.0µin depending on the specific part number.

Q: Are BERGSTIK® II parts compatible with TSW headers? A: Yes. All BERGSTIK® II variants (68000, 68001, 68002 series) are compatible substitutes. They share identical pitch, position count, row configuration, and contact geometry. Primary differences are post length (0.095", 0.120", or 0.150") and operating temperature range (-65°C ~ 125°C or -65°C ~ 130°C), which exceed the TSW-112-08-T-S specification.

Q: What post length should I select? A: Post length selection depends on PCB thickness and application requirements. The TSW-112-08-T-S features 0.200" post length. BERGSTIK® II variants offer 0.095", 0.120", or 0.150" post lengths. Verify PCB compatibility before selection.

Q: Are all substitute parts RoHS compliant? A: Yes. The Molex parts are ROHS3 compliant. Amphenol ICC BERGSTIK® II parts are RoHS compliant. All alternatives meet environmental compliance requirements.

Q: What is the operating temperature range for substitute parts? A: The TSW-112-08-T-S operates from -55°C to 105°C. Molex KK254 parts do not specify operating temperature. Amphenol ICC BERGSTIK® II parts operate from -65°C to 125°C (68000, 68001 series) or -65°C to 130°C (68002 series), providing extended thermal performance.

Q: Can I mix different manufacturers in the same assembly? A: Yes, provided all parts meet the application's electrical and mechanical requirements. Verify connector compatibility with mating receptacles and ensure consistent contact finish specifications across the assembly for optimal performance.
