Engineering Selection Recommendations

Primary Recommendation: Molex 0683002006

The Molex 0683002006 (KK254 series) is the preferred substitute for new designs and production transitions. This part maintains full electrical and mechanical compatibility with the original 861400051YO2 while offering ROHS3 compliance and active product status. The KK254 series is widely adopted across automotive, medical, and telecommunications applications, ensuring long-term supply chain stability and cost optimization. Current inventory of 780 pieces supports immediate deployment.

Secondary Recommendation: 3M 929647-01-05-EU or 929647-09-05-I

The 3M 929 series (929647-01-05-EU and 929647-09-05-I) provides RoHS-compliant alternatives with breakaway header configuration matching the original design intent. These parts feature gold-plated mating contacts and operate across -40°C to 105°C temperature range. The 929647-01-05-EU variant is recommended for European applications due to REACH compliance status. Both variants maintain 2.5A current rating and UL94 V-0 flammability certification. Inventory availability exceeds 1,700 pieces combined.

Alternative Option: 3M 2305-6211-TG

The 3M 2305 series (2305-6211-TG) offers a non-compliant alternative for legacy system maintenance where RoHS compliance is not required. This part matches the original 3A current rating and provides identical pitch and position configuration. Operating temperature range extends to -55°C, suitable for extended environmental applications. Inventory of 1,140 pieces supports sustained production requirements.

Compliance Consideration: 3M 961105-6804-AR

The 3M 961 series (961105-6804-AR) provides a RoHS-compliant option with flash gold finish on mating contacts. This part operates at 2A current rating and -25°C to 105°C temperature range. Selection of this variant should be evaluated against application current requirements, as the 2A rating represents the lowest among available substitutes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0683002006 directly replace the Amphenol ICC 861400051YO2 in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (5), row configuration (1), contact type (male pin), mounting method (through hole), and termination (solder). Mechanical and electrical compatibility is confirmed. The primary difference is product status transition from obsolete to active, with improved RoHS compliance.

Q: What is the significance of the current rating difference between the original 3A and substitute parts rated at 2.5A or 2A?

A: Current rating represents the maximum continuous current the connector contacts can safely conduct. The original 861400051YO2 is rated 3A. Substitutes with 2.5A or 2A ratings remain suitable for applications operating below their respective thresholds. Applications requiring sustained currents above 2.5A should specify the Molex 0683002006 (unspecified but typically equivalent) or 3M 2305-6211-TG (3A rated). Verify application current requirements before selection.

Q: Are there differences in contact length between the original and substitute parts?

A: Yes. Contact length variations exist across substitute options. The original 861400051YO2 specifies 0.276" (7.00mm) mating contact length and 0.118" (3.00mm) post length. Substitute parts vary: Molex 0683002006 (0.250" mating, 0.200" post), 3M 2305-6211-TG (0.318" mating, 0.120" post), and 3M 929 series (0.235" mating, 0.110" post). These variations affect board-to-board spacing and mating depth. Verify PCB layout compatibility before implementation.

Q: Which substitute part offers the best long-term supply chain availability?

A: The Molex 0683002006 (KK254 series) is recommended for supply chain stability. This series is actively manufactured, widely distributed across multiple channels, and maintains consistent inventory levels. The 3M 929 series variants also provide strong availability with combined inventory exceeding 3,600 pieces. Both manufacturers maintain active product status, ensuring continued production and support.

Q: What is the difference between RoHS-compliant and non-compliant parts in this selection?

A: RoHS (Restriction of Hazardous Substances) compliance restricts use of lead, cadmium, mercury, and other hazardous materials in electrical components. The original 861400051YO2 is RoHS non-compliant. Substitute parts classified as ROHS3 Compliant (Molex 0683002006) or RoHS Compliant (3M 929 series, 961 series) meet current regulatory requirements for EU and global markets. Selection depends on application geography and regulatory requirements. Non-compliant alternatives (3M 2305-6211-TG) remain available for legacy system maintenance where compliance is not mandated.

Q: Can the 3M 929 series variants (929647-01-05-EU, 929647-09-05-I, 929647-03-05-I) be used interchangeably?

A: The 929647-01-05-EU and 929647-09-05-I variants are electrically and mechanically interchangeable, both rated 2.5A with identical mating contact length (0.235"). The 929647-03-05-I variant differs in post length (0.410" versus 0.110"), affecting overall connector height and board spacing. Selection between 929647-01-05-EU and 929647-09-05-I depends on regional compliance requirements (EU versus general use). The 929647-03-05-I should be selected only when extended post length is required for specific PCB stack-up configurations.

Q: What packaging options are available for production quantities?

A: Substitute parts are available in bulk packaging, supporting high-volume production requirements. Molex 0683002006, 3M 2305-6211-TG, and all 3M 929 series variants are supplied in bulk format. Samtec DW-05-16-F-S-250 is also available in bulk. Bulk packaging eliminates individual component packaging, reducing material costs and waste for production environments. Confirm packaging specifications with supplier for specific quantity requirements.
