Amphenol ICC 68002-402 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68002-402 is a vertical rectangular connector header with 2 positions at 2.54mm pitch, designed for through-hole board-to-board applications. This component features male pins with tin-plated phosphor bronze contacts rated for 3A at operating temperatures from -65°C to 130°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the 0.100" (2.54mm) pitch standard and support the same electrical and mechanical interface requirements.

Engineering Selection Recommendations

Active Product Substitutes (Recommended for New Designs):

The Molex KK254 series parts (0050291692, 0050291883, 0423751922, 0423752486, 0423752521) are active products with ROHS3 compliance, making them suitable for applications requiring modern regulatory compliance. These parts maintain full mechanical and electrical compatibility with the 68002-402 interface. The Molex series offers multiple contact finish options (tin or gold) to accommodate different application requirements.

The 3M 929 series parts (929450-01-02-I and 9R9647-01-02-EU) are active products with RoHS compliance. The 9R9647-01-02-EU is particularly suitable as it matches the original part's operating temperature range more closely and offers press-fit termination options in addition to solder termination.

Considerations for Temperature-Sensitive Applications:

The 68002-402 operates from -65°C to 130°C. Most substitute parts operate within -40°C to 105°C or -55°C to 105°C ranges. The TE Connectivity 4-103327-0-02 extends to -65°C on the lower end, matching the original specification. Applications requiring the full -65°C to 130°C range should evaluate thermal performance requirements against substitute part specifications.

RoHS Compliance Transition:

The original 68002-402 is RoHS non-compliant. For applications transitioning to RoHS-compliant designs, Molex KK254 series (ROHS3 compliant) or 3M 929 series (RoHS compliant) parts provide direct substitution with regulatory compliance.

Current Rating Considerations:

The 68002-402 is rated for 3A. Molex and 3M 2300 series parts maintain 3A ratings. The 3M 929 series parts are rated for 2.5A, which is acceptable for most applications but should be verified for high-current designs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different contact finish (gold vs. tin)?

A: Yes. Both tin and gold contact finishes are acceptable for 2.54mm pitch connectors. Gold-plated contacts provide enhanced corrosion resistance and are suitable for applications with extended shelf life or harsh environments. Tin-plated contacts are standard for general-purpose applications. The choice depends on application requirements rather than compatibility.

Q: What is the difference between standard header and breakaway header connectors?

A: Breakaway headers feature perforated insulation that allows individual positions to be separated after assembly. Standard headers maintain a solid insulation body. Both types are mechanically and electrically compatible with 2.54mm pitch receptacles. Breakaway variants offer design flexibility for applications requiring individual pin extraction.

Q: Are the Molex KK254 series parts direct replacements for the 68002-402?

A: Yes. The Molex KK254 series (0050291692, 0050291883, 0423751922, 0423752486, 0423752521) are direct mechanical and electrical replacements. All parts maintain 0.100" (2.54mm) pitch, 2-position, single-row configuration with square male pins, push-pull fastening, and UL94 V-0 flammability rating. The primary differences are contact finish options and RoHS compliance status.

Q: Why do some substitute parts show no current rating specified?

A: Current ratings are not always provided in manufacturer datasheets for all connector variants. Molex KK254 series parts are designed for general-purpose applications with current handling equivalent to the 68002-402. Specific current requirements should be verified against application load conditions.

Q: Can I use the 3M 929 series parts rated for 2.5A in place of the 3A-rated 68002-402?

A: The 3M 929 series (929450-01-02-I and 9R9647-01-02-EU) are rated for 2.5A. These parts are suitable for applications with current requirements up to 2.5A. For applications requiring the full 3A rating, Molex KK254 series or 3M 2300 series parts are recommended.

Q: What is the difference between kinked pin and standard solder termination?

A: Kinked pin termination (featured in Molex 0050291883) provides enhanced mechanical retention in the PCB during soldering by creating a bent contact path. Standard solder termination uses straight pins. Both termination types are compatible with standard PCB through-holes and provide equivalent electrical performance.

Q: Are there any temperature range limitations I should consider when substituting?

A: The 68002-402 operates from -65°C to 130°C. Most substitute parts operate within narrower ranges (-40°C to 105°C or -55°C to 105°C). For applications requiring operation at the extreme temperature limits of the original part, verify that the selected substitute meets your specific thermal requirements. The TE Connectivity 4-103327-0-02 extends to -65°C on the lower end.

Q: What packaging options are available for these substitute parts?

A: Molex KK254 series parts are supplied in bulk packaging. 3M 929 and 2300 series parts are available in bulk or tape packaging depending on the specific part number. Packaging selection depends on assembly volume and handling requirements. Consult manufacturer datasheets for specific packaging availability.
