Engineering Selection Recommendations

MQ115-8P-2A(41) is the primary substitute for the obsolete MQ115-8P-2A(21). This part maintains active product status with Hirose Electric Co Ltd, ensuring continuous availability and supply chain stability. The MQ115-8P-2A(41) carries RoHS compliance certification and meets the same MSL Level 1 rating. The connector features friction lock fastening, solder termination, and UL94 V-0 flammability rating, supporting reliable board-level integration at the specified 2A current and 250VAC voltage ratings.

MQ115-8P-2A(71) serves as an alternative substitute, also maintaining active product status. This variant differs in fastening mechanism, employing push-pull fastening instead of friction lock. The MQ115-8P-2A(71) provides identical electrical specifications (2A, 250VAC), material composition (Copper Alloy contacts, PBT insulation), and mechanical dimensions. Selection between MQ115-8P-2A(41) and MQ115-8P-2A(71) depends on mating interface requirements and fastening preference within the application.

Both substitute parts satisfy compliance requirements through MSL Level 1 rating and material flammability standards, supporting deployment in standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Why is the MQ115-8P-2A(21) no longer available?

A: The MQ115-8P-2A(21) has reached obsolete status within Hirose Electric Co Ltd's product portfolio. Active substitute parts within the MQ115 series provide equivalent functionality with improved supply chain continuity.
