150234-6002-RB Equivalent & Substitute Parts

Part Overview

The 150234-6002-RB is a 34-position rectangular receptacle connector manufactured by 3M, designed for board-to-board or cable applications with through-hole solder termination. This connector features a 0.079" (2.00mm) pitch, gold-plated mating contacts, and push-pull fastening. The part is active in production and widely used in applications requiring reliable interconnection with moderate current handling (1A at 500VDC).

Finding equivalent or substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for alternative solutions that maintain functional compatibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the 150234-6002-RB is determined by strict alignment with the following critical parameters:

Connector Type & Position Count: Must be a 34-position receptacle connector
Pitch & Row Configuration: Must maintain 0.079" (2.00mm) mating pitch with 2-row layout
Mounting & Termination: Must support through-hole solder termination with push-pull fastening
Contact System: Must feature gold-plated mating contacts with female socket configuration
Electrical Performance: Must meet or exceed 500V rating and 1A current capacity
Compliance: Must maintain ROHS3 compliance and UL94 V-0 flammability rating

The M22-7141742 from Harwin Inc. qualifies as a manufacturer-recommended substitute based on these parameters. Both connectors share identical position count, pitch, row spacing, mounting method, fastening type, and contact finish material. Electrical ratings are compatible, with the substitute offering enhanced current capacity (2A vs. 1A) and voltage flexibility (500VAC vs. 500VDC).

Engineering Selection Recommendations

Both the 150234-6002-RB and M22-7141742 maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on the following engineering considerations:

Primary Part (150234-6002-RB): Use when the extended lower operating temperature limit (-55°C) is required for the application, or when the specific mechanical envelope defined by the 0.177" insulation height and 0.100" contact post length is critical to PCB layout and mating interface design.

Substitute Part (M22-7141742): Use when supply availability of the primary part is constrained or when the application can operate within the -40°C to 105°C temperature range. The substitute offers higher current capacity (2A) and voltage flexibility (500VAC), providing design margin for applications with moderate current demands. The dimensional variance in insulation height (0.173" vs. 0.177") and contact post length (0.094" vs. 0.100") must be evaluated against specific PCB layout requirements and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can M22-7141742 be used as a direct drop-in replacement for 150234-6002-RB?

A: Both connectors share identical position count, pitch, row configuration, mounting method, and fastening type. However, dimensional differences in insulation height and contact post length require verification against your specific PCB layout and mating connector specifications before implementation.

Q: What is the temperature operating range difference between these parts?

A: The 150234-6002-RB operates from -55°C to 105°C, while the M22-7141742 operates from -40°C to 105°C. If your application requires operation below -40°C, the primary part is required. For applications within -40°C to 105°C, both parts are suitable.

Q: Are the electrical ratings compatible?

A: Yes. The primary part is rated for 1A at 500VDC. The substitute is rated for 2A at 500VAC. Both meet or exceed the electrical requirements of the primary part. The substitute provides additional current capacity margin.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching connector type, position count (34), mating pitch (0.079"), row configuration (2 rows), mounting method (through-hole), termination type (solder), fastening mechanism (push-pull), contact finish (gold), and compliance certifications (ROHS3, UL94 V-0).

Q: How do the insulation materials differ?

A: The 150234-6002-RB uses thermoplastic insulation, while the M22-7141742 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and chemical resistance in industrial environments.

Q: What inventory levels are available?

A: The 150234-6002-RB has 967 pieces in stock. The M22-7141742 has 1612 pieces in stock, providing greater availability for immediate procurement needs.
