Engineering Selection Recommendations
The 70232-125LF is the direct substitute for the obsolete 70232-125. Both connectors maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.
The primary distinction between these parts is product lifecycle status and regulatory compliance. The 70232-125 is obsolete and does not meet RoHS requirements. The 70232-125LF is an active product that achieves RoHS compliance, making it the appropriate selection for new designs and ongoing production support.
For applications requiring the 24-position, 4-row, 2.00mm pitch through-hole header connector within the Metral® series, the 70232-125LF provides equivalent performance with the advantage of current manufacturing availability and regulatory alignment.
Frequently Asked Questions (FAQ)
Q: Are the 70232-125 and 70232-125LF mechanically interchangeable?
A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (24), row configuration (4), and through-hole mounting specifications. They are mechanically interchangeable in PCB designs.
Q: What is the difference between these two part numbers?
A: The 70232-125LF is the active production equivalent of the obsolete 70232-125. The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). Electrical and mechanical specifications remain identical.
Q: Can I use the 70232-125LF as a direct replacement in existing assemblies?
A: Yes. The 70232-125LF maintains all critical electrical parameters including 1A current rating, gold contact finish at 30.0µin thickness, UL94 V-0 flammability rating, and -55°C to 125°C operating temperature range. No design modifications are required.
Q: What packaging is available for the substitute part?
A: The 70232-125LF is supplied in tube packaging, whereas the original 70232-125 packaging specification was not provided. Confirm packaging requirements with your procurement process.
Q: Are there any compliance considerations when switching to the 70232-125LF?
A: The 70232-125LF achieves RoHS compliance, which may be required for new designs or updated product certifications. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
Q: What is the moisture sensitivity level for these connectors?
A: Both the 70232-125 and 70232-125LF are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
