MQ115-24P-6A(21) Equivalent & Substitute Parts

Part Overview

The MQ115-24P-6A(21) is a 24-position rectangular connector manufactured by Hirose Electric Co Ltd, classified as a through-hole mounted receptacle for board-to-cable/wire applications. This part is currently obsolete, making identification of active equivalent models essential for ongoing design support and procurement. Substitute parts must maintain the same 24-position configuration and core electrical ratings to ensure functional compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MQ115-24P-6A(21) are identified based on the following critical parameters that determine functional equivalence:

• Series Alignment: All substitutes belong to the MQ115 series, ensuring mechanical and electrical compatibility
• Position Count: All substitutes maintain 24 positions, preserving pin configuration
• Contact Type: All substitutes use male pin contacts, matching the original specification
• Mounting Method: All substitutes are through-hole mounted, maintaining PCB integration approach
• Electrical Ratings: All substitutes maintain 2A current rating and 250VAC voltage rating
• Compliance: All substitutes maintain RoHS compliance and MSL 1 rating

The substitutes differ in fastening mechanism (friction lock versus push-pull) and connector type designation (header versus receptacle), but these variations remain within the MQ115 series compatibility envelope.

Parameter Comparison

Engineering Selection Recommendations

Both MQ115-24P-6A(41) and MQ115-24P-6A(71) are active products within the MQ115 series and serve as direct functional substitutes for the obsolete MQ115-24P-6A(21). Selection between these two options depends on fastening mechanism requirements:

• MQ115-24P-6A(41) employs friction lock fastening, suitable for applications requiring secure retention without additional mechanical intervention
• MQ115-24P-6A(71) employs push-pull fastening, appropriate for applications requiring quick-disconnect capability

Both substitutes maintain full RoHS compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and storage requirements. Current inventory levels support both options: 977 units for MQ115-24P-6A(41) and 892 units for MQ115-24P-6A(71).

Frequently Asked Questions (FAQ)

Q: Can MQ115-24P-6A(41) and MQ115-24P-6A(71) be used interchangeably with MQ115-24P-6A(21)?

A: Both parts maintain the same 24-position configuration, male pin contact type, through-hole mounting, and electrical ratings (2A, 250VAC). The primary difference is the fastening mechanism. Interchangeability depends on whether your application requires friction lock or push-pull fastening.

Q: What is the significance of the fastening type difference?

A: Friction lock fastening (MQ115-24P-6A(41)) provides continuous retention through mechanical pressure. Push-pull fastening (MQ115-24P-6A(71)) allows for rapid connection and disconnection. Select based on your application's mating/unmating frequency requirements.

Q: Are all three parts RoHS compliant?

A: The MQ115-24P-6A(21) is ROHS3 compliant. Both active substitutes (MQ115-24P-6A(41) and MQ115-24P-6A(71)) are RoHS compliant. All three maintain MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Q: What packaging options are available?

A: MQ115-24P-6A(41) is supplied in tray packaging. MQ115-24P-6A(71) packaging information is not specified in available data. Confirm packaging requirements with your procurement process.

Q: Are there pitch or row spacing specifications for these connectors?

A: Pitch and row spacing data are not provided in the available specifications for any of these three part numbers. Contact Hirose Electric Co Ltd directly for detailed mechanical drawings if these parameters are critical to your application.
