MB1RJN0801 Circular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The MB1RJN0801 is an 8-position circular connector receptacle housing manufactured by Amphenol Sine Systems Corp, part of the MotionGrade™ M23 Power Standard Series. This panel-mount, right-angle connector is designed for male pins with mixed contact sizes (1.0mm and 2.0mm configurations). The product is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system integration and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB1RJN0801 is based on strict alignment of the following critical parameters:

Electrical & Mechanical Compatibility Criteria:

• Number of Positions: 8 (4 + 3 Power + PE)
• Shell Size - Insert: M23-8
• Contact Type: Crimp
• Contact Size: 1.0mm (4), 2.0mm (4)
• Connector Type: Receptacle Housing for Male Pins
• Mounting Type: Panel Mount, Right Angle
• Fastening Type: Threaded
• Orientation: Keyed
• Ingress Protection: IP67
• Material Flammability Rating: UL94 V-0
• Operating Temperature: -20°C ~ 130°C

The MB7RJN0801 is identified as a direct substitute. Both connectors share identical electrical pin configurations, shell sizes, contact specifications, and environmental ratings. The primary distinction is product status and the inclusion of a rotatable backshell feature on the MB7RJN0801, which does not affect core compatibility. The MB7RJN0801 is currently active in production, making it the recommended alternative for the obsolete MB1RJN0801.

Parameter Comparison

Engineering Selection Recommendations

The MB7RJN0801 is the primary substitute for the obsolete MB1RJN0801. Selection is based on the following factors:

Product Status: The MB7RJN0801 holds Active product status with 1142 units in current stock, ensuring long-term supply availability. The MB1RJN0801, classified as Obsolete, presents procurement and lifecycle management constraints.

Regulatory Compliance: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and UL94 V-0 flammability certification, satisfying equivalent environmental and safety standards for applications within the specified operating temperature range of -20°C to 130°C.

Mechanical Compatibility: Both connectors utilize M23-8 shell sizing with threaded fastening, keyed orientation, and identical contact specifications (1.0mm and 2.0mm crimp contacts). Panel-mount, right-angle configurations with flange mounting features ensure direct mounting compatibility.

Enhanced Features: The MB7RJN0801 includes a rotatable backshell, providing improved cable strain relief and service accessibility without compromising electrical performance or environmental sealing (IP67 rating maintained).

Frequently Asked Questions (FAQ)

Q: Can the MB7RJN0801 directly replace the MB1RJN0801 in existing installations? A: Yes. Both connectors share identical electrical pin configurations, shell sizes, contact types and sizes, mounting interfaces, fastening mechanisms, and environmental protection ratings. The addition of a rotatable backshell on the MB7RJN0801 does not alter electrical compatibility or mechanical fit within standard M23-8 panel-mount applications.

Q: What is the impact of the rotatable backshell feature on the MB7RJN0801? A: The rotatable backshell provides enhanced strain relief and cable routing flexibility without affecting core connector functionality, electrical performance, or IP67 ingress protection rating.

Q: Are there any material or environmental rating differences between these parts? A: No. Both connectors utilize zinc die-cast nickel-plated shells with polyamide insert material. Operating temperature ranges (-20°C to 130°C), flammability ratings (UL94 V-0), RoHS3 compliance, and REACH status are identical.

Q: What is the significance of the contact size designation (1.0mm and 2.0mm)? A: Contact sizes determine pin gauge and current-carrying capacity. Both parts maintain the same configuration: four 1.0mm contacts for signal lines and four 2.0mm contacts for power distribution, including PE (protective earth) connections.

Q: Is there a packaging difference between these parts? A: The MB1RJN0801 is packaged as standard product with 737 units in stock, while the MB7RJN0801 is supplied in Bulk packaging with 1142 units available. Bulk packaging does not affect individual part specifications or functionality.

Q: Are contacts included with these connectors? A: No. Both the MB1RJN0801 and MB7RJN0801 are supplied as connector housings without contacts. Contacts must be procured separately based on application requirements.
