Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MQ115-12P-3A(21) is determined by the following critical parameters:

• Series Alignment: All substitute parts must belong to the MQ115 series
• Position Count: 12-position configuration required
• Connector Architecture: Receptacle with male pin contact type
• Mounting Method: Through-hole mounting only
• Electrical Ratings: Minimum 2A current rating and 250VAC voltage rating
• Compliance: RoHS compliance and MSL Level 1 rating
• Material Specifications: Copper alloy contacts with polybutylene terephthalate (PBT) insulation

Two active substitute parts meet these criteria within the MQ115 series: MQ115-12P-3A(41) and MQ115-12P-3A(71).

Parameter Comparison

Engineering Selection Recommendations

Both MQ115-12P-3A(41) and MQ115-12P-3A(71) are active production alternatives to the obsolete MQ115-12P-3A(21). Selection between these two substitutes depends on fastening mechanism requirements:

MQ115-12P-3A(41) features friction lock fastening and is packaged in trays, suitable for applications requiring standard mechanical retention without additional locking mechanisms.

MQ115-12P-3A(71) incorporates push-pull fastening, appropriate for applications demanding positive engagement and secure mating cycles.

Both parts maintain identical electrical specifications (2A at 250VAC), material composition (copper alloy contacts with PBT insulation), and compliance certifications (RoHS and UL94 V-0). The choice between these substitutes should be based solely on the mechanical fastening requirement of the target application.

Frequently Asked Questions (FAQ)

Q: Can MQ115-12P-3A(41) and MQ115-12P-3A(71) be used interchangeably with MQ115-12P-3A(21)?

A: Both parts share identical electrical ratings, contact materials, and insulation specifications. Interchangeability depends on fastening mechanism compatibility. The original MQ115-12P-3A(21) fastening type is not specified in available documentation; therefore, the fastening mechanism of the selected substitute must match the mating connector design in the target application.

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

A: Friction lock fastening (MQ115-12P-3A(41)) relies on mechanical friction to maintain connector engagement. Push-pull fastening (MQ115-12P-3A(71)) uses a positive locking mechanism requiring deliberate action to disconnect, providing higher security against accidental separation.

Q: Are there packaging differences between the substitute parts?

A: MQ115-12P-3A(41) is supplied in tray packaging. MQ115-12P-3A(71) packaging specification is not provided in available data. Packaging selection should be coordinated with procurement and assembly requirements.

Q: Do both substitutes meet the same compliance standards as the original part?

A: Both substitutes are RoHS compliant with UL94 V-0 material flammability rating and MSL Level 1 moisture sensitivity rating. The original part carries ROHS3 compliance; substitutes carry RoHS compliance. Both ratings satisfy RoHS directive requirements.

Q: What is the current inventory status for these substitutes?

A: MQ115-12P-3A(41) has 1114 pieces in stock. MQ115-12P-3A(71) has 701 pieces in stock. Both are classified as active production parts.
