Amphenol ICC 70232-121 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 70232-121 is a 24-position PCB header connector with male pins designed for through-hole mounting applications. This connector belongs to the Metral® series and features press-fit termination with gold-plated contacts rated for 1A continuous current operation across an extended temperature range of -55°C to 125°C.

The 70232-121 carries an obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. The substitute part 70232-121LF provides direct functional equivalence while maintaining active product status and improved compliance posture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70232-121 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 24 positions (non-negotiable)
• Pitch Specification: 0.079" (2.00mm) standard spacing
• Row Configuration: 4-row arrangement
• Termination Method: Press-fit contact technology
• Contact Material & Finish: Gold plating at 30.0µin thickness
• Current Capacity: 1A rating
• Temperature Operating Range: -55°C to 125°C
• Flammability Compliance: UL94 V-0 classification

The 70232-121LF meets all these criteria without deviation, establishing it as a direct functional equivalent. The primary distinction lies in product lifecycle status and regulatory compliance improvements rather than electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 70232-121LF is the appropriate selection for applications currently using or specifying the 70232-121. The substitute part maintains complete electrical and mechanical compatibility while offering the following advantages:

Product Lifecycle: The 70232-121LF carries active product status, ensuring continued availability and manufacturing support. The 70232-121 is obsolete and subject to discontinuation without notice.

Regulatory Compliance: The 70232-121LF is RoHS compliant, meeting current environmental regulations for new product designs and procurement in regulated markets. The 70232-121 is non-compliant and may present compliance barriers in jurisdictions with mandatory RoHS requirements.

Supply Chain Stability: Current inventory of 926 pieces for the 70232-121LF supports production continuity. The 70232-121 inventory of 973 pieces represents a finite supply with no replenishment capability.

Packaging: The 70232-121LF is supplied in tray packaging, standard for automated assembly operations and component handling.

Frequently Asked Questions (FAQ)

Q: Are the 70232-121 and 70232-121LF mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), row configuration (4 rows), position count (24), and through-hole mounting specifications. PCB footprints are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and regulatory compliance. The 70232-121LF is an active product with RoHS compliance, while the 70232-121 is obsolete and non-compliant. Electrical and mechanical performance characteristics are equivalent.

Q: Can I use 70232-121LF as a direct replacement in existing designs?

A: Yes. The 70232-121LF is a direct functional equivalent with no design modifications required. Existing PCB layouts, assembly processes, and electrical connections remain unchanged.

Q: Does the color difference (Natural vs. Natural/White) affect electrical performance?

A: No. Color is a cosmetic characteristic only and does not impact electrical properties, current rating, temperature performance, or contact reliability.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free compliance, reflecting the RoHS-compliant manufacturing process used for this variant.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts maintain identical current rating (1A), operating temperature range (-55°C to 125°C), contact finish specifications (gold, 30.0µin), and flammability rating (UL94 V-0).

Q: What packaging considerations apply to the 70232-121LF?

A: The 70232-121LF is supplied in tray packaging, suitable for both manual and automated assembly operations. Tray packaging provides component protection and facilitates pick-and-place handling.
