Engineering Selection Recommendations
For RoHS3 Compliant Designs:
Molex KK254 series parts (0022285086, 0050291620, 0423750671, 0423752492) are active status components with full ROHS3 compliance and REACH unaffected status. These parts maintain square contact geometry consistent with the original 68031-508H and provide gold mating finish. Inventory availability ranges from 762 to 1050 pieces.
Preci-Dip 350 and 800 series parts (350-10-108-01-666101, 350-80-108-00-013101, 350-80-108-01-666101, 350-V3-108-00-006101, 800-80-008-10-001101) are active status components with ROHS3 compliance and REACH unaffected status. These parts feature circular contact geometry and operating temperature range of -55°C to 125°C. Inventory availability ranges from 618 to 991 pieces.
For Legacy RoHS Non-Compliant Designs:
The TE Connectivity 4-103185-0-08 (AMPMODU Mod II series) maintains obsolete status and RoHS non-compliant classification, matching the original part's regulatory profile. This part provides square contact geometry and 3A current rating. Inventory availability is 1174 pieces.
Compliance Considerations:
All substitute parts listed maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level, consistent with the original specification. ROHS3 compliant options are recommended for new designs and procurement cycles where regulatory compliance is required.
Frequently Asked Questions (FAQ)
Q: Can I substitute a Preci-Dip circular contact connector for the original square contact Amphenol ICC part?
A: Yes. Both square and circular contact geometries are acceptable substitutes when all other critical parameters match: 0.100" (2.54mm) pitch, 8 positions, 1 row, through-hole mounting, push-pull fastening, and UL94 V-0 flammability rating. The contact shape difference does not affect electrical or mechanical compatibility in this connector category.
Q: What is the difference between the Molex parts with different part numbers?
A: The Molex KK254 series parts differ in contact length specifications and number of positions loaded. Part 0423750671 has 7 positions loaded versus 8 positions loaded in the other variants. Contact length variations range from 0.232" to 0.240" for mating contacts and 0.125" to 0.153" for post contacts. These variations maintain compatibility with standard 0.100" (2.54mm) pitch spacing and do not affect substitution eligibility.
Q: Are there current or voltage rating differences between the original part and substitutes?
A: The original 68031-508H specifies 5A current rating and 110V voltage rating. Molex KK254 series parts do not specify current or voltage ratings in the provided data. Preci-Dip 350 and 800 series parts specify 3A current rating and 150VDC voltage rating. TE Connectivity 4-103185-0-08 specifies 3A current rating. For applications requiring the original 5A rating, verify substitute part datasheets for current handling capability.
Q: Should I choose an active status part over an obsolete part?
A: Active status parts provide ongoing manufacturer support, availability, and design continuity. All Molex and Preci-Dip substitutes listed are active status with ROHS3 compliance. The TE Connectivity 4-103185-0-08 is obsolete status. For new designs and long-term procurement, active status parts are recommended.
Q: What is the significance of ROHS3 compliance for these connectors?
A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original 68031-508H is RoHS non-compliant. All Molex and Preci-Dip substitutes are ROHS3 compliant with REACH unaffected status, making them suitable for applications subject to environmental regulations.
Q: Can I use parts with different contact finishes interchangeably?
A: Gold and tin contact finishes are both acceptable for mating surfaces in this connector category. Gold finish (0022285086, 0050291620, 0423750671, 0423752492, 350-10-108-01-666101, 350-V3-108-00-006101, 4-103185-0-08) provides enhanced corrosion resistance. Tin finish (350-80-108-00-013101, 350-80-108-01-666101, 800-80-008-10-001101) is cost-effective and suitable for standard applications. Selection depends on environmental exposure and application requirements.
Q: What is the operating temperature range for these connectors?
A: The original 68031-508H does not specify an operating temperature range. Preci-Dip 350 and 800 series parts specify -55°C to 125°C operating range. TE Connectivity 4-103185-0-08 specifies -65°C to 105°C. Molex KK254 series parts do not specify operating temperature in the provided data. For temperature-critical applications, consult detailed datasheets for thermal performance specifications.
