MQ115-32P-8A(21) Equivalent & Substitute Parts

Part Overview

The MQ115-32P-8A(21) is a 32-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 32-position configuration and core electrical ratings to ensure functional compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MQ115-32P-8A(21) is determined by the following critical parameters:

• Series Alignment: All substitutes must belong to the MQ115 series
• Position Count: Exact match of 32 positions required
• Connector Type: Receptacle configuration maintained
• Contact Type: Male pin contacts required
• Mounting Method: Through-hole mounting preserved
• Electrical Ratings: Current rating (2A) and voltage rating (250VAC) must be met or exceeded
• Material Compliance: RoHS compliance and MSL rating of 1 (Unlimited) required

The two active substitutes identified—MQ115-32P-8A(41) and MQ115-32P-8A(71)—satisfy all these criteria while offering active product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Both MQ115-32P-8A(41) and MQ115-32P-8A(71) are active products with current manufacturing support and full RoHS compliance, making them suitable replacements for the obsolete MQ115-32P-8A(21).

MQ115-32P-8A(41) features friction lock fastening and is packaged in trays, offering standard board-to-cable/wire connectivity with established supply chain availability (981 pcs in stock).

MQ115-32P-8A(71) employs push-pull fastening and maintains equivalent electrical and mechanical specifications. This variant provides an alternative fastening mechanism for applications requiring quick-disconnect capability (780 pcs in stock).

Selection between these two substitutes depends on the fastening requirement of the target application: friction lock for permanent or semi-permanent connections, or push-pull for frequent mating/unmating cycles.

Frequently Asked Questions (FAQ)

Q: Can MQ115-32P-8A(41) and MQ115-32P-8A(71) be used interchangeably with MQ115-32P-8A(21)?

A: Both parts maintain the same 32-position configuration, through-hole mounting, electrical ratings (2A, 250VAC), and material specifications. The primary difference is the fastening mechanism: friction lock versus push-pull. Interchangeability depends on whether the application requires a specific fastening type.

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

A: Friction lock fastening provides a secure, semi-permanent connection suitable for applications with infrequent disconnection. Push-pull fastening enables quick-disconnect capability, allowing rapid mating and unmating without tools.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both MQ115-32P-8A(41) and MQ115-32P-8A(71) are RoHS compliant with MSL rating of 1 (Unlimited), meeting the same environmental and regulatory standards as the original part.

Q: What packaging options are available for these substitutes?

A: MQ115-32P-8A(41) is supplied in trays. MQ115-32P-8A(71) packaging information is not specified in the available data.

Q: Do these substitutes support the same current and voltage ratings?

A: Yes. Both substitutes are rated for 2A current and 250VAC voltage, matching the electrical requirements of the original MQ115-32P-8A(21).
