Substitute Part Grouping Explanation

The MB5RJN0801 qualifies as a direct substitute for the MB2RJN0801 based on the following critical parameters:

Substitution-Determining Parameters:

Identical connector type: Receptacle housing for male pins
Identical position configuration: 8 positions (4 + 3 Power + PE)
Identical shell size: M23-8
Identical mounting configuration: Panel mount, right angle with flange
Identical contact specifications: 1.0mm (4) and 2.0mm Power (4)
Identical fastening mechanism: Push-Twist with keyed orientation
Identical environmental rating: IP67 (Dust Tight, Waterproof)
Identical thermal operating range: -20°C to 130°C
Identical shell construction: Zinc die cast with nickel finish
Identical electrical properties: Shielded configuration
Identical compliance: ROHS3 compliant

The primary distinction is product status: MB5RJN0801 is Active, whereas MB2RJN0801 is Obsolete. This substitution maintains full electrical and mechanical compatibility.

Engineering Selection Recommendations

For New Designs: Select MB5RJN0801. This part is Active status with established supply availability (1039 pcs in stock) and full ROHS3 compliance, ensuring long-term manufacturability and regulatory alignment.

For Legacy System Maintenance: MB5RJN0801 provides full electrical and mechanical interchangeability with MB2RJN0801 (Obsolete). The substitute maintains identical pin configuration, shell size, mounting geometry, and environmental specifications, ensuring drop-in compatibility in existing applications.

Compliance Verification: Both parts comply with ROHS3, REACH Unaffected, and carry EAR99 ECCN classification. UL94 V-0 material flammability rating is consistent across both models.

Frequently Asked Questions (FAQ)

Q: Can MB5RJN0801 directly replace MB2RJN0801 in existing assemblies? A: Yes. MB5RJN0801 is mechanically and electrically identical to MB2RJN0801 across all critical dimensions and specifications. Panel mount holes, right-angle orientation, shell size M23-8, contact positions, and operating temperature range are unchanged.

Q: Why is the original MB2RJN0801 obsolete? A: Product status reflects manufacturer discontinuation. MB5RJN0801 represents the active alternative maintaining the same electrical and mechanical interface specifications.

Q: Are there packaging differences between these parts? A: MB2RJN0801 packaging is unspecified ("-"), while MB5RJN0801 is supplied in Bulk packaging. Both parts have identical physical dimensions and mounting characteristics; packaging differences do not affect component performance or compatibility.

Q: What are the critical parameters for substitution compatibility? A: Substitution is valid when connector type, position count (8 positions), shell size (M23-8), contact sizes (1.0mm and 2.0mm), mounting type (panel mount, right angle), fastening mechanism (push-twist), ingress protection (IP67), and operating temperature range (-20°C to 130°C) are preserved.

Q: Do these connectors include contacts? A: No. Both MB2RJN0801 and MB5RJN0801 are receptacle housings supplied without contacts. Contacts must be procured separately and terminated using crimp methods.

Q: Are both parts RoHS compliant? A: Yes. Both MB2RJN0801 and MB5RJN0801 comply with ROHS3 standards and are unaffected by REACH regulations.
