Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MQ115-16P-4A(21) are identified based on the following critical parameters that determine functional compatibility:

• Series Alignment: All substitutes belong to the MQ115 series, ensuring mechanical and electrical compatibility within the connector family
• Position Count: All alternatives maintain 16 positions, preserving pin count requirements
• Connector Classification: All substitutes are receptacle connectors with male pin contact type
• Mounting Method: All alternatives utilize through-hole mounting, matching the original installation approach
• Termination Type: All substitutes employ solder termination, consistent with the base product design

The two identified substitutes differ in fastening mechanism and specific packaging configurations but maintain core electrical and mechanical parameters necessary for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both MQ115-16P-4A(41) and MQ115-16P-4A(71) are active product alternatives to the obsolete MQ115-16P-4A(21). Selection between these substitutes depends on fastening mechanism requirements:

MQ115-16P-4A(41) features friction lock fastening and is packaged in trays. This variant maintains RoHS compliance certification and is suitable for applications requiring secure mechanical retention through friction-based locking.

MQ115-16P-4A(71) employs push-pull fastening and offers an alternative connection mechanism. This variant provides the same electrical and mechanical core specifications with a different engagement method.

Both substitutes maintain identical position count, contact type, mounting method, and termination approach. Both achieve MSL Level 1 rating and support the same electrical parameters (2A current, 250VAC voltage). The choice between variants should be based on the specific fastening mechanism required by the application and connector housing design.

Frequently Asked Questions (FAQ)

Q: Can MQ115-16P-4A(41) and MQ115-16P-4A(71) be used interchangeably with MQ115-16P-4A(21)?

A: Both substitutes maintain the same 16-position configuration, male pin contact type, through-hole mounting, and solder termination. However, they differ in fastening mechanism. MQ115-16P-4A(41) uses friction lock fastening, while MQ115-16P-4A(71) uses push-pull fastening. Compatibility depends on whether the mating connector and application design accommodate the specific fastening type.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is the fastening mechanism. MQ115-16P-4A(41) employs friction lock fastening, while MQ115-16P-4A(71) uses push-pull fastening. Both maintain identical electrical ratings (2A, 250VAC) and physical dimensions (0.138" post length, 0.571" insulation height).

Q: Are both substitutes RoHS compliant?

A: MQ115-16P-4A(41) is explicitly RoHS compliant. MQ115-16P-4A(71) RoHS status is not specified in the available data. Both parts maintain MSL Level 1 rating and UL94 V-0 flammability certification.

Q: What packaging options are available for these substitutes?

A: MQ115-16P-4A(41) is supplied in tray packaging. MQ115-16P-4A(71) packaging specification is not provided in the available data.

Q: Do these substitutes support the same electrical specifications as the original part?

A: Both substitutes are rated for 2A current and 250VAC voltage. The original part's electrical specifications are not fully documented, but the substitutes provide standard electrical parameters for this connector class.
