Amphenol ICC 67997-450 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-450 is a vertical rectangular connector header featuring 50 positions with 0.100" (2.54mm) pitch spacing. This through-hole component is designed for board-to-board applications with solder termination and push-pull fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. The BERGSTIK® II series connector operates across a temperature range of -65°C to 130°C with a current rating of 3A per contact and UL94 V-0 flammability compliance.

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 67997-450 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Pitch spacing: 0.100" (2.54mm) mating pitch and row spacing
• Contact type: Male pin configuration
• Mounting method: Through-hole solder termination
• Fastening mechanism: Push-pull engagement
• Current capacity: 3A per contact minimum
• Operating temperature range: Minimum -65°C to 130°C coverage
• Flammability rating: UL94 V-0 compliance
• Connector style: Board-to-board or board-to-cable compatibility

The TE Connectivity AMP Connectors part number 9-146254-0 qualifies as a functional substitute based on these parameters. While the substitute features 80 positions compared to the original 50 positions, both components share identical pitch spacing, contact configuration, mounting methodology, and electrical ratings. The substitute maintains the required current capacity and flammability certification. The primary distinction is the increased position count, which does not prevent substitution in applications where the additional positions can be accommodated or left unloaded.

Engineering Selection Recommendations

Product Status Consideration: The Amphenol ICC 67997-450 is classified as obsolete, indicating discontinued production and limited long-term availability. The TE Connectivity 9-146254-0 maintains active production status, ensuring reliable procurement for current and future applications.

Compliance and Certification: The substitute part 9-146254-0 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the substitute provides regulatory advantage. Both components maintain UL94 V-0 flammability certification, meeting fire safety standards.

Temperature Range Limitation: The substitute part operates to a maximum of 105°C compared to the original 130°C upper limit. Applications requiring sustained operation above 105°C cannot use the substitute without thermal performance verification. For standard industrial and commercial applications operating within -65°C to 105°C, the substitute is fully qualified.

Position Count Differential: The substitute provides 80 positions versus the original 50 positions. PCB layout accommodation is required. In applications where only 50 positions are needed, the additional 30 positions may remain unloaded without functional impact, provided board space permits the larger connector footprint.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 9-146254-0 directly replace the Amphenol ICC 67997-450 in all applications?

A: Direct replacement is possible for applications operating within -65°C to 105°C. Applications requiring operation above 105°C require alternative solutions, as the substitute's maximum temperature rating is 105°C versus the original 130°C. PCB layout must accommodate the 80-position connector footprint.

Q: What is the significance of the position count difference (50 vs. 80)?

A: The substitute provides 30 additional positions. In applications requiring exactly 50 positions, the extra positions remain unused. PCB design must verify that the larger connector footprint fits within available board space. Electrical performance is unaffected by unloaded positions.

Q: Are the contact materials interchangeable?

A: The original uses phosphor bronze contacts while the substitute uses copper alloy contacts. Both materials provide equivalent electrical conductivity and current-carrying capacity at the 3A rating. Contact finish specifications (tin plating at 100.0µin thickness) are identical, ensuring compatible mating characteristics.

Q: Does the RoHS3 compliance of the substitute affect compatibility?

A: RoHS3 compliance of the substitute is advantageous for regulatory adherence. The original part's RoHS non-compliance does not prevent physical or electrical substitution but may create compliance documentation requirements in regulated industries. The substitute eliminates this compliance concern.

Q: What packaging differences exist between these parts?

A: The original part is supplied in bag packaging with 760 pieces in stock. The substitute is supplied in tube packaging with 1526 pieces in stock. Packaging format does not affect connector performance or compatibility.

Q: Are the insulation materials compatible?

A: The original part does not specify insulation material. The substitute uses Liquid Crystal Polymer (LCP) insulation, which provides superior dimensional stability and chemical resistance compared to standard materials. This represents a material improvement without compatibility concerns.
