Parameter Comparison

Engineering Selection Recommendations

The Molex 0387206312 is the direct equivalent for the obsolete 0387208112. Both parts share identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product status: the 0387206312 maintains active manufacturing status with current inventory availability (969 pcs), whereas the 0387208112 is obsolete with limited stock (1056 pcs).

For new designs or ongoing production requiring 12-circuit barrier block connectors with 0.375" pitch, 15A/300V ratings, and through-hole mounting, the 0387206312 is the appropriate selection. Both parts comply with ROHS3 requirements and UL94 V-0 flammability standards, ensuring regulatory compliance across industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 0387206312 directly replace the 0387208112 in existing designs?

A: Yes. The 0387206312 is electrically and mechanically equivalent to the 0387208112. All critical parameters including circuit count, pitch, current/voltage ratings, termination types, and mounting configuration are identical. PCB layouts and wire gauges require no modification.

Q: What is the difference between these two parts?

A: The primary difference is product lifecycle status. The 0387208112 is obsolete, while the 0387206312 is active. The 0387206312 is packaged in trays versus the 0387208112's unspecified packaging. All functional and electrical characteristics are equivalent.

Q: Are there any compatibility concerns with the packaging difference?

A: No. Packaging format (tray versus bulk) does not affect component performance or PCB assembly compatibility. The connector itself maintains identical form factor and electrical properties.

Q: What wire gauges are compatible with these connectors?

A: Both parts accept wire gauges from 14 AWG to 22 AWG. Wire selection should be based on circuit current requirements and application voltage specifications.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate across the temperature range of -40°C to 100°C. Applications requiring operation outside this range require alternative component selection.

Q: Do these connectors meet current regulatory standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting current industrial and commercial regulatory requirements.
