Key Parameters

Substitute Part Grouping Explanation

The Amphenol ICC 70234-148 qualifies as a direct substitute for the 70234-948 based on the following critical parameters that determine functional equivalence:

• Connector Configuration: Both parts maintain identical position count (96), pitch (2.00mm), row arrangement (4 rows), and connector type (header, male pins)
• Electrical Specifications: Current rating (1A) and operating temperature range (-55°C to 125°C) are identical
• Mechanical Interface: Both use through-hole mounting with press-fit termination, ensuring compatibility with existing PCB designs
• Series Designation: Both belong to the Metral® series, confirming design family compatibility
• Compliance Standards: Both meet UL94 V-0 flammability requirements

The primary distinction is product status: the 70234-148 is active and available, whereas the 70234-948 is obsolete. The 70234-148 includes gold contact finish (30.0µin/0.76µm thickness) compared to the unspecified finish of the 70234-948, representing an enhancement in contact reliability and corrosion resistance.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 70234-148 is the appropriate selection for applications currently specified with the 70234-948. The substitute maintains full electrical and mechanical compatibility while offering the advantage of active product status and established supply chain availability. Both parts share identical compliance certifications (UL94 V-0, EAR99 ECCN classification) and environmental specifications (MSL 1, operating temperature -55°C to 125°C).

The gold contact finish on the 70234-148 provides enhanced contact durability and oxidation resistance compared to the unspecified finish of the obsolete 70234-948, making it suitable for long-term reliability requirements. Both parts are RoHS non-compliant, maintaining consistency with legacy system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 70234-148 be used as a direct replacement for the 70234-948 in existing designs?

A: Yes. The 70234-148 maintains identical connector configuration (96 positions, 2.00mm pitch, 4-row layout), electrical ratings (1A current, -55°C to 125°C operating range), and mechanical interface (through-hole, press-fit termination). No PCB redesign is required.

Q: What is the difference between the contact finishes?

A: The 70234-948 contact finish is not specified in available documentation. The 70234-148 features a gold contact finish with 30.0µin (0.76µm) thickness, which provides superior corrosion resistance and contact reliability over extended operational life.

Q: Are there packaging differences between these parts?

A: The 70234-948 packaging is not specified. The 70234-148 is supplied in tube packaging, which is standard for high-position-count connector headers and facilitates automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 70234-948 and 70234-148 meet UL94 V-0 flammability requirements, carry EAR99 ECCN classification, and are classified as REACH Unaffected. Both are RoHS non-compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the 70234-948 classified as obsolete?

A: The 70234-948 has been superseded by the 70234-148 within the Amphenol ICC product portfolio. The 70234-148 offers improved contact finish specifications and maintains active manufacturing status, making it the recommended selection for new and ongoing applications.
