Amphenol ICC 67997-406H Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-406H is a vertical board-to-board rectangular connector header with 6 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This through-hole solder-terminated component features unshrouded male pins with square contact geometry and phosphor bronze material. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from multiple manufacturers provide direct functional replacement while offering improved compliance status and availability.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 67997-406HLF

The 67997-406HLF is the direct active successor to the obsolete 67997-406H. Both components share identical BERGSTIK® II series specifications, including contact geometry, pitch, row spacing, and operating temperature range (-65°C ~ 130°C). The 406HLF variant achieves RoHS compliance and REACH affected status, addressing regulatory requirements while maintaining full electrical and mechanical compatibility. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendations for Regulatory Compliance:

TE Connectivity 5-146254-3 (AMPMODU Mod II series) and the Mill-Max/Preci-Dip 450 series options provide ROHS3 compliance with active product status. The TE part operates to 105°C, which is acceptable for most applications within the original -65°C to 130°C envelope. The 450 series variants from Mill-Max and Preci-Dip offer extended temperature capability to 125°C and full UL94 V-0 flammability certification.

Alternative for Gold-Plated Contacts:

The 3M 2300 series (2306-6121-TB, 2306-6121-TG, 2306-6121-TP) provides gold-plated mating surfaces with equivalent mechanical specifications. These parts maintain UL94 V-0 rating and 3A current capacity but operate to 105°C maximum. Selection among TB, TG, and TP variants depends on specific contact finish thickness requirements.

Consideration for Circular Contact Geometry:

The Mill-Max 450-10-206-00-001000 and Preci-Dip 450-10-206-00-001101 variants feature circular contact geometry instead of square. While mechanically and electrically compatible, circular contacts present a geometric variation that may require mechanical validation in applications with tight tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 67997-406HLF directly replace the obsolete 67997-406H without PCB modification?

A: Yes. The 67997-406HLF maintains identical pitch spacing (0.100" mating and row spacing), contact count (6 positions in 2 rows), mounting type (through-hole solder), and overall contact length specifications. No PCB redesign is required.

Q: What is the primary difference between the main part and its direct successor?

A: The 67997-406HLF achieves RoHS compliance and REACH affected status while the original 67997-406H is RoHS non-compliant. Both operate across the same temperature range (-65°C ~ 130°C) and share identical electrical ratings (3A, UL94 V-0).

Q: Are the 3M 2300 series parts (2306-6121-TB, TG, TP) suitable for high-temperature applications?

A: The 3M 2300 series operates to 105°C maximum, which is lower than the original part's 130°C upper limit. These parts are suitable for applications with operating temperatures not exceeding 105°C. For applications requiring the full -65°C ~ 130°C range, select the 67997-406HLF or TE Connectivity 5-146254-3 alternatives.

Q: What is the significance of contact finish differences (Tin vs. Gold)?

A: Contact finish affects corrosion resistance and mating force characteristics. Tin-plated contacts (67997-406H, 67997-406HLF, 5-146254-3) provide standard performance for general applications. Gold-plated contacts (3M 2300 series, Mill-Max/Preci-Dip 450 series) offer enhanced corrosion resistance and are preferred for high-reliability or harsh environment applications. Both finishes maintain the 3A current rating and are electrically equivalent.

Q: Can I use the Mill-Max or Preci-Dip 450 series parts with circular contacts instead of square contacts?

A: The 450 series variants are mechanically and electrically compatible substitutes. Circular contact geometry is functionally equivalent to square geometry for this connector class. However, applications with tight mechanical tolerances or specific contact pressure requirements should validate compatibility before production implementation.

Q: Which substitute offers the best compliance profile for new designs?

A: The TE Connectivity 5-146254-3 and Mill-Max/Preci-Dip 450 series variants achieve ROHS3 compliance with active product status. For designs requiring maximum regulatory alignment and long-term availability, these options provide superior compliance posture compared to the RoHS non-compliant 3M 2300 series.

Q: Are there packaging differences between substitutes that affect procurement?

A: Yes. The 67997-406HLF is supplied in bag packaging, TE Connectivity 5-146254-3 in bulk, 3M 2300 series in unspecified packaging, and Mill-Max 450 series in tube packaging. Preci-Dip 450 variants are supplied in bulk. Packaging selection should align with assembly process requirements and inventory management practices.

Q: What is the current rating for the Mill-Max 450-10-206-00-001000 variant?

A: The 450-10-206-00-001000 specification does not provide a current rating value. The Preci-Dip equivalent (450-10-206-00-001101) is rated at 3A, matching the original part. For applications requiring confirmed 3A capacity, select the Preci-Dip variant or other substitutes with explicit current ratings.
