Substitute Part Grouping Explanation

Substitution for the MQ115-2PA-1A(21) is determined by the following criteria derived from the provided specifications:

• Series alignment: All substitutes belong to the MQ115 series
• Position count: All substitutes maintain 2-position configuration
• Connector classification: All substitutes are rectangular connectors with male pin contact type
• Mounting method: All substitutes utilize through-hole, right-angle mounting
• Termination: All substitutes employ solder termination
• Shrouding: All substitutes feature shrouded 4-wall design
• Electrical ratings: All substitutes maintain 2A current rating and 250VAC voltage rating
• Material compliance: All substitutes use Polybutylene Terephthalate (PBT) insulation and Copper Alloy contacts
• Regulatory compliance: All substitutes maintain MSL 1 (Unlimited) classification

Parameter Comparison

Engineering Selection Recommendations

Both MQ115-2PA-1A(41) and MQ115-2PA-1A(71) are active product alternatives to the obsolete MQ115-2PA-1A(21). Selection between these substitutes depends on fastening mechanism requirements:

The MQ115-2PA-1A(41) employs friction lock fastening and specifies a 0.100" (2.54mm) mating pitch, providing standard board-to-cable/wire connectivity with defined dimensional parameters.

The MQ115-2PA-1A(71) employs push-pull fastening with specified contact post length of 0.118" (3.00mm) and insulation height of 0.295" (7.50mm), offering alternative mechanical engagement characteristics.

Both substitutes maintain identical electrical ratings (2A, 250VAC), material composition (Copper Alloy contacts, PBT insulation), compliance certifications (UL94 V-0, RoHS, MSL 1), and connector architecture (2-position, through-hole right-angle, shrouded 4-wall design).

Frequently Asked Questions (FAQ)

Q: Why is the MQ115-2PA-1A(21) no longer available?

A: The MQ115-2PA-1A(21) has reached end-of-life status and is classified as obsolete. Active alternatives within the MQ115 series are available to fulfill equivalent functional requirements.

Q: Are MQ115-2PA-1A(41) and MQ115-2PA-1A(71) fully interchangeable with MQ115-2PA-1A(21)?

A: Both parts share the same series designation, position count, contact type, mounting method, termination type, and electrical ratings. The primary differences are fastening mechanism (friction lock versus push-pull) and specific dimensional parameters. Mechanical compatibility must be verified against your application's connector receptacle design.

Q: What is the difference between friction lock and push-pull fastening?

A: Friction lock fastening (MQ115-2PA-1A(41)) relies on mechanical friction to maintain connector engagement. Push-pull fastening (MQ115-2PA-1A(71)) uses a push-to-connect and pull-to-disconnect mechanism. Selection depends on your application's mating connector type and operational requirements.

Q: Do all three parts meet the same compliance standards?

A: The MQ115-2PA-1A(21) is ROHS3 compliant. Both MQ115-2PA-1A(41) and MQ115-2PA-1A(71) are RoHS compliant. All three maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification.

Q: What packaging is available for the substitute parts?

A: MQ115-2PA-1A(41) is supplied in tray packaging. MQ115-2PA-1A(71) packaging specification is not provided in the available data.

Q: Are there any dimensional differences I should consider?

A: MQ115-2PA-1A(41) specifies 0.100" (2.54mm) mating pitch. MQ115-2PA-1A(71) specifies contact post length of 0.118" (3.00mm) and insulation height of 0.295" (7.50mm). Verify these dimensions against your PCB layout and mating connector specifications before implementation.
