Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70232-145 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 24 positions, 4 rows, 0.079" (2.00mm) pitch
• Electrical Performance: 1A current rating maintained across full operating temperature range
• Physical Interface: Through-hole mounting with press-fit termination
• Contact Properties: Gold plating at 30.0µin (0.76µm) thickness
• Environmental Compliance: UL94 V-0 flammability rating
• Temperature Range: -55°C to 125°C operational limits

The identified substitute part maintains identical electrical, mechanical, and environmental specifications while differing in product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 70232-145LF serves as the direct functional equivalent to the obsolete 70232-145. Both parts maintain identical electrical and mechanical specifications within the Metral® connector series.

The 70232-145LF is classified as active product status, ensuring ongoing availability and manufacturer support. This part carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution in restricted substance compliance frameworks.

Selection of the 70232-145LF is appropriate for new designs, production continuity, and field replacement applications where the 70232-145 is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Are the 70232-145 and 70232-145LF mechanically interchangeable?

A: Yes. Both connectors share identical physical dimensions, pitch spacing (0.079" / 2.00mm), mounting configuration (through-hole), and termination method (press-fit). PCB layout and mechanical mounting requirements are identical.

Q: What is the functional difference between these two parts?

A: There is no functional difference. Both parts deliver identical electrical performance: 24-position configuration, 1A current rating, and -55°C to 125°C operating temperature range. The primary differences are product lifecycle status and regulatory compliance classification.

Q: Why does the 70232-145LF have different REACH and RoHS designations?

A: The 70232-145LF is an active product subject to current regulatory compliance frameworks. The 70232-145, being obsolete, is classified as REACH Unaffected. For new applications and ongoing production, the 70232-145LF meets modern environmental and substance restriction requirements.

Q: Does packaging differ between these parts?

A: Yes. The 70232-145 uses standard packaging, while the 70232-145LF is supplied in tube packaging. This difference does not affect electrical or mechanical performance and relates only to handling, storage, and logistics considerations.

Q: Can the 70232-145LF be used as a direct replacement in existing assemblies?

A: Yes. The 70232-145LF is a direct substitute for the 70232-145 in all applications. No design modifications, PCB layout changes, or electrical circuit adjustments are required.
