Key Parameters

Substitute Part Grouping Explanation

Substitution of the MQ115-24PA-6A(21) is based on the following critical parameters that must align between the main part and substitute candidates:

• Series Compatibility: Both parts belong to the MQ115 series, ensuring mechanical and electrical interface compatibility
• Position Count: 24-position configuration maintained across all substitutes
• Connector Type: Receptacle male through-hole configuration
• Product Status: Active status required for ongoing procurement and supply chain reliability
• Compliance Standards: RoHS3 compliance and MSL rating of 1 (Unlimited) maintained
• Electrical Ratings: Current and voltage ratings must support the intended application

The MQ115-24PA-6A(71) qualifies as a direct substitute based on these parameters, with the primary distinction being its active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The MQ115-24PA-6A(71) is the qualified substitute for the obsolete MQ115-24PA-6A(21). Selection is based on the following engineering criteria:

• Product Status: The MQ115-24PA-6A(71) maintains active status, ensuring long-term procurement viability and supply chain continuity
• Compliance Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory and environmental requirements
• Series Continuity: Both connectors belong to the MQ115 series, guaranteeing mechanical and electrical interface compatibility
• Electrical Specifications: The substitute provides defined electrical ratings (2A current, 250VAC voltage) with UL94 V-0 flammability certification, supporting safety-critical applications
• Inventory Status: The substitute demonstrates higher current inventory levels, reducing procurement lead times

The primary design consideration is the right-angle mounting configuration of the MQ115-24PA-6A(71), which differs from the main part specification. PCB layout and mechanical clearance must be evaluated to confirm compatibility with the intended application.

Frequently Asked Questions (FAQ)

Q: Can the MQ115-24PA-6A(71) be used as a direct replacement for the MQ115-24PA-6A(21)?

A: The MQ115-24PA-6A(71) is electrically and mechanically compatible as a substitute within the MQ115 series. Both maintain 24-position configuration, identical contact type, and equivalent compliance standards. The primary design difference is the right-angle mounting orientation, which must be evaluated against PCB layout requirements.

Q: What is the significance of the product status difference between these parts?

A: The MQ115-24PA-6A(21) is classified as obsolete, indicating discontinued manufacturing and limited future availability. The MQ115-24PA-6A(71) maintains active status, ensuring ongoing production, stable pricing, and reliable supply chain access for current and future procurement needs.

Q: Are both parts RoHS compliant?

A: Yes, both the MQ115-24PA-6A(21) and MQ115-24PA-6A(71) are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What does MSL 1 (Unlimited) indicate?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal sensitivity to moisture absorption during storage and handling. No special moisture control measures or baking procedures are required prior to soldering or assembly.

Q: How do the electrical ratings of the substitute compare to the main part?

A: The MQ115-24PA-6A(71) specifies 2A current rating and 250VAC voltage rating with UL94 V-0 flammability certification. The main part does not provide detailed electrical specifications in the available documentation. Application requirements must be evaluated to confirm the substitute's ratings are adequate.

Q: What is the difference between straight and right-angle mounting configurations?

A: Straight through-hole mounting positions the connector perpendicular to the PCB surface. Right-angle mounting positions the connector parallel to the PCB surface. This affects PCB layout, mechanical clearance, and cable routing. Design verification is required to confirm compatibility with existing mechanical and electrical layouts.
