Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MQ115-4P-1A(21) is determined by the following critical parameters:

• Same manufacturer (Hirose Electric Co Ltd)
• Same series designation (MQ115)
• Identical number of positions (4)
• Matching connector type (Receptacle)
• Matching contact type (Male Pin)
• Single row configuration
• Through-hole mounting capability
• Solder termination method
• Equivalent electrical ratings (2A current, 250VAC voltage)
• Active product status for continued availability

The substitute parts MQ115-4P-1A(41) and MQ115-4P-1A(71) meet these criteria while offering active product status and documented inventory availability.

Parameter Comparison

Engineering Selection Recommendations

MQ115-4P-1A(41) is the primary substitute for MQ115-4P-1A(21). Both components share identical connector type designation (Header/Receptacle), fastening mechanism (Friction Lock), and all critical electrical and mechanical parameters. The MQ115-4P-1A(41) maintains active product status with documented inventory of 947 pieces, ensuring procurement continuity. RoHS compliance is maintained across both components.

MQ115-4P-1A(71) serves as a secondary alternative. This part differs in fastening type (Push-Pull instead of Friction Lock) and connector type designation (Receptacle). The electrical ratings, dimensional specifications, and material composition remain equivalent. Active product status with 1133 pieces in inventory provides supply security. The fastening mechanism difference requires mechanical design verification for applications where friction lock engagement is functionally critical.

Both substitutes comply with RoHS regulations and maintain MSL 1 classification, supporting unrestricted storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can MQ115-4P-1A(41) directly replace MQ115-4P-1A(21) in existing designs?

A: Yes. Both components share identical electrical ratings (2A, 250VAC), mechanical dimensions (0.138" post length, 0.571" insulation height), contact configuration (4-position, single row, square contacts), and fastening mechanism (Friction Lock). The primary difference is product status; MQ115-4P-1A(41) is active while MQ115-4P-1A(21) is obsolete.

Q: What is the difference between MQ115-4P-1A(41) and MQ115-4P-1A(71)?

A: The primary distinction is fastening type. MQ115-4P-1A(41) uses Friction Lock engagement, while MQ115-4P-1A(71) uses Push-Pull engagement. Both maintain identical electrical specifications, dimensional parameters, and material composition. Connector type designation differs (Header vs. Receptacle), though both are 4-position male pin receptacles with through-hole solder termination.

Q: Are there packaging differences between these substitutes?

A: MQ115-4P-1A(41) is supplied in Tray packaging. MQ115-4P-1A(71) packaging information is not specified in available documentation. Confirm packaging requirements with procurement specifications before finalizing component selection.

Q: Do all three parts meet RoHS compliance requirements?

A: MQ115-4P-1A(21) is ROHS3 Compliant. MQ115-4P-1A(41) and MQ115-4P-1A(71) are RoHS Compliant. Both compliance levels satisfy current regulatory requirements for electronic component procurement.

Q: What is the pitch specification for these connectors?

A: Pitch specifications are not provided in the available technical documentation for any of these three part numbers. Contact the manufacturer or authorized distributor for detailed pitch information if this parameter is critical for your application.
