Amphenol ICC 67997-112 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-112 is a rectangular connector header designed for through-hole board-to-board applications. This 12-position, 2-row connector operates at 0.100" (2.54mm) pitch and is rated for 3A current with an operating temperature range of -65°C to 130°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 67997-112 is based on the following critical electrical and mechanical parameters:

• Pitch and Position Compatibility: Mating pitch of 0.100" (2.54mm) with 2-row configuration
• Contact Type and Material: Male pin contacts with gold mating surface finish
• Mounting and Termination: Through-hole solder termination for board-to-board applications
• Current and Temperature Rating: Minimum 3A current capacity and operating temperature range compatibility
• Mechanical Dimensions: Contact length, insulation height, and overall form factor consistency
• Compliance and Flammability: UL94 V-0 material flammability rating

The substitute part TE Connectivity AMP Connectors 4-103186-0 shares these core parameters, though it is available in an 80-position breakaway configuration. This part maintains electrical and mechanical compatibility at the individual contact level while offering extended position capacity through its modular breakaway design.

Parameter Comparison

Engineering Selection Recommendations

Both the 67997-112 and 4-103186-0 are classified as obsolete products. Selection between these parts should be based on the following engineering criteria:

Amphenol ICC 67997-112: Use when a fixed 12-position, 2-row configuration is required. This part maintains the original design specifications with a maximum operating temperature of 130°C and phosphor bronze contact material.

TE Connectivity AMP Connectors 4-103186-0: Use when modular position flexibility is needed through breakaway capability. This part supports up to 80 positions while maintaining the same 0.100" (2.54mm) pitch and row spacing. The maximum operating temperature is 105°C, which is lower than the original part. The insulation height is 0.090" (2.54mm) compared to 0.100" (2.54mm) on the original part.

Both parts carry identical current ratings (3A), flammability ratings (UL94 V-0), and moisture sensitivity levels (MSL 1). Both are RoHS non-compliant and share the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103186-0 directly replace the Amphenol ICC 67997-112 in a 12-position application?

A: The 4-103186-0 can functionally replace the 67997-112 at the contact level due to matching pitch (0.100" / 2.54mm), row spacing, contact type, and current rating. However, the 4-103186-0 is a breakaway header with 80 total positions. For a 12-position requirement, only 12 positions would be used, with the remaining 68 positions either broken away or left unused. The insulation height difference (0.090" vs. 0.100") and maximum operating temperature difference (105°C vs. 130°C) must be evaluated against application requirements.

Q: What are the key electrical compatibility factors between these parts?

A: Both parts share identical current ratings (3A), contact type (male pin), mating pitch (0.100" / 2.54mm), and row spacing (0.100" / 2.54mm). Both use gold mating surface finishes and square contact shapes. These parameters ensure electrical compatibility at the contact interface level.

Q: Are there mechanical compatibility concerns?

A: The overall contact length differs slightly (0.450" vs. 0.440"), and the insulation height differs (0.100" vs. 0.090"). These dimensional variations may affect board layout and mating depth. The 4-103186-0 uses thermoplastic insulation material compared to unspecified insulation material on the 67997-112. These differences should be evaluated against specific PCB design and mating connector specifications.

Q: What is the significance of the breakaway feature on the 4-103186-0?

A: The breakaway feature allows the 80-position header to be segmented into smaller configurations. For applications requiring exactly 12 positions, the header can be broken away to the required size, or individual positions can be left unused. This provides design flexibility but requires mechanical modification if exact 12-position form factor is critical.

Q: How do the operating temperature ranges compare?

A: The 67997-112 operates from -65°C to 130°C, while the 4-103186-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the 4-103186-0 as a substitute.

Q: Are both parts still available for procurement?

A: Both parts are classified as obsolete. The 67997-112 has 1,103 pieces listed as new original in stock, while the 4-103186-0 has 126,300 pieces available. Availability should be confirmed with authorized distributors before design decisions are finalized.
