Engineering Selection Recommendations

Both the MS112BPC and M112BPCX are Active product status components manufactured by Switchcraft Inc. and maintain full ROHS3 compliance. The M112BPCX offers higher inventory availability (1196 units versus 865 units), making it a viable alternative for procurement scenarios requiring extended lead times or larger order quantities. Both parts meet identical electrical and mechanical specifications for 6.35mm stereo headphone jack applications with solder termination and panel-mount installation. Selection between these parts should be based on packaging requirements, inventory availability, and procurement timelines, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the M112BPCX be used as a direct replacement for the MS112BPC in existing designs?

A: Yes. The M112BPCX is electrically and mechanically equivalent to the MS112BPC. Both connectors feature identical 6.35mm stereo (TRS) configurations, solder termination, panel-mount through-hole installation, and operate within the same temperature and voltage specifications. No design modifications are required.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (Phone Jack, Stereo), signal configuration (3 Conductor, TRS), mating diameter (6.35mm), number of contacts (3), mounting type (Panel Mount, Through Hole), termination method (Solder), panel hole size (0.375"), thread size (3/8"-32), operating temperature range (-20°C ~ 65°C), voltage rating (48VDC), and current rating (250 mA). Both parts match all these parameters.

Q: What is the difference between the MS112BPC and M112BPCX?

A: The primary difference is packaging format. The M112BPCX is supplied in Bulk packaging, while the MS112BPC packaging specification is not detailed. Additionally, the M112BPCX has higher inventory availability (1196 units versus 865 units). All electrical, mechanical, and compliance specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the MS112BPC and M112BPCX are ROHS3 compliant and suitable for applications requiring environmental compliance standards.

Q: What is the current rating for these connectors?

A: Both connectors are rated for 250 mA maximum current at 48VDC, suitable for standard audio and low-power signal applications.
