Substitute Part Grouping Explanation

Substitution eligibility for the 150210-2020-RB is determined by strict alignment of the following critical parameters:

10-position receptacle configuration with 2-row layout
0.079" (2.00mm) mating pitch and row spacing
Surface mount solder termination
Push-pull fastening mechanism
Gold-plated mating contacts
Square contact geometry
UL94 V-0 flammability rating
RoHS compliance status

The identified substitute parts (A3-10DA-2SV(71), A3A-10DA-2SV(71), and M22-6340542) satisfy these core mechanical and electrical compatibility criteria. Variations in secondary parameters such as insulation material, contact finish thickness, operating temperature range, and voltage rating are documented to enable informed selection based on specific application requirements.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS and REACH requirements. Selection between the 150210-2020-RB and substitute options depends on application-specific electrical and thermal constraints:

The A3-10DA-2SV(71) and A3A-10DA-2SV(71) from Hirose Electric are mechanically and functionally compatible but operate at reduced maximum temperature (-55°C to 85°C versus -55°C to 105°C) and lower voltage rating (200VAC versus 500VDC). The A3A-10DA-2SV(71) includes board guide features matching the original design. These parts are suitable for general purpose and telecommunications applications within their specified operating ranges.

The M22-6340542 from Harwin Inc. supports higher current capacity (2A versus 1A) and maintains the full operating temperature range (-40°C to 105°C) with 500VAC voltage rating. This part features bottom or top entry configuration and is rated for industrial applications. The higher current rating provides design margin for applications requiring increased power delivery.

Frequently Asked Questions (FAQ)

Q: Can A3-10DA-2SV(71) or A3A-10DA-2SV(71) be used in applications requiring 500VDC operation?

A: No. These Hirose parts are rated for 200VAC maximum. The 150210-2020-RB and M22-6340542 are rated for 500VDC and 500VAC respectively and must be used for higher voltage applications.

Q: What is the difference between A3-10DA-2SV(71) and A3A-10DA-2SV(71)?

A: Both parts are functionally equivalent with identical electrical specifications. The A3A-10DA-2SV(71) includes board guide features, matching the original 150210-2020-RB design. Selection depends on whether board guide functionality is required for the application.

Q: Is M22-6340542 suitable for applications operating above 105°C?

A: No. The M22-6340542 operates to 105°C maximum. For applications requiring higher temperature operation, the 150210-2020-RB supports -55°C to 105°C.

Q: Can the M22-6340542 be used as a direct replacement in existing designs?

A: Mechanical compatibility is maintained through identical pitch, row spacing, and surface mount configuration. However, the bottom or top entry connector style may require PCB layout verification. The higher current rating (2A) is backward compatible with 1A designs.

Q: Are all substitute parts available in the same packaging format?

A: No. The 150210-2020-RB is supplied in Tray packaging. A3-10DA-2SV(71) and A3A-10DA-2SV(71) are supplied in Tube packaging. M22-6340542 is supplied in Tube packaging. Packaging format may affect procurement and handling procedures.

Q: What insulation materials are used in each connector?

A: The 150210-2020-RB uses Thermoplastic insulation. A3-10DA-2SV(71) and A3A-10DA-2SV(71) use Polyphenylene Sulfide (PPS). M22-6340542 uses Polyamide (PA6T), Nylon 6T. Material selection affects chemical resistance and thermal performance in specific environments.
