Contact finish selection depends on application requirements. The MTSW-106-23-L-S-240 features gold mating contacts at 10.0µin thickness. Amphenol ICC BERGSTIK® II parts (68000-206HLF, 68001-106HLF, 68001-206HLF) offer gold or gold GXT™ finishes with 15.0µin or 30.0µin thickness. Amphenol ICC BERGSTIK® parts (77311-122-06LF, 77311-124-06LF, 77311-822-06LF) provide gold or gold GXT™ finishes with 15.0µin or 30.0µin thickness. Molex KK254 parts 0022284061 and 0022284062 feature tin mating contacts; 0022284064 and 0022284067 feature gold mating contacts.

Operating temperature range extends to -65°C on Amphenol ICC BERGSTIK® series parts compared to -55°C on the MTSW-106-23-L-S-240. All parts maintain 3A current rating and UL94 V-0 flammability compliance. Moisture sensitivity level is 1 (Unlimited) across all parts.

Frequently Asked Questions (FAQ)

Q: What are the core compatibility criteria for substituting the MTSW-106-23-L-S-240?

A: The substitute must maintain 0.100" (2.54mm) pitch, 6 positions in a single row, male pin contact type, through-hole mounting, solder termination, push-pull fastening, unshrouded design, and UL94 V-0 flammability rating. All listed substitutes meet these requirements.

Q: Can Molex KK254 series parts replace the MTSW-106-23-L-S-240?

A: Yes. Molex parts 0022284061, 0022284062, 0022284064, and 0022284067 are functionally compatible. Differences include insulation material (Polyamide/Nylon vs. Polyester), insulation height (0.090" vs. 0.100"), and contact finish options. Contact length variations range from 0.295" to 0.320" mating length.

Q: What is the difference between Amphenol ICC BERGSTIK® and BERGSTIK® II series?

A: BERGSTIK® II parts (68000-206HLF, 68001-106HLF, 68001-206HLF) feature unspecified insulation material and contact material. BERGSTIK® parts (77311-122-06LF, 77311-124-06LF, 77311-822-06LF) specify Thermoplastic insulation material and Phosphor Bronze contact material. Both series support the same pitch, position count, and electrical ratings.

Q: How do contact finish thickness variations affect substitution?

A: Contact finish thickness is a permitted variation parameter. The MTSW-106-23-L-S-240 specifies 10.0µin (0.25µm) gold mating finish. Substitutes range from 15.0µin to 100.0µin thickness. Thicker finishes provide enhanced wear resistance and corrosion protection in high-cycle mating applications.

Q: Are there packaging differences between substitutes?

A: Yes. The MTSW-106-23-L-S-240 is supplied in Bulk packaging. Molex KK254 parts are Bulk packaged. Amphenol ICC BERGSTIK® II parts (68000-206HLF, 68001-106HLF, 68001-206HLF) are Bag packaged. Amphenol ICC BERGSTIK® parts (77311-122-06LF, 77311-124-06LF, 77311-822-06LF) are Bulk packaged. Packaging does not affect electrical or mechanical compatibility.

Q: Which substitutes offer the widest operating temperature range?

A: Amphenol ICC BERGSTIK® and BERGSTIK® II series parts operate from -65°C to 125°C, compared to -55°C to 125°C for the MTSW-106-23-L-S-240. This extended lower temperature range is available across all Amphenol ICC substitutes listed.

Q: What is the significance of REACH Affected vs. REACH Unaffected status?

A: REACH Unaffected parts (MTSW-106-23-L-S-240, Molex KK254 series, Amphenol ICC 77311 series) are not subject to REACH substance restrictions. REACH Affected parts (Amphenol ICC 68000 and 68001 series) may contain substances of concern and require compliance documentation. Selection depends on regulatory requirements for the end application.
