Substitute Part Grouping Explanation

Substitution of the A3B-26PA-2DS(71) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count and row configuration (26 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting orientation (Through Hole, Right Angle)
• Termination method (Kinked Pin, Solder)
• Contact material and finish specifications (Brass with Gold mating finish)
• Insulation material (Polyamide/Nylon)
• Electrical ratings (1A, 200VAC)
• Temperature range (-55°C ~ 85°C)
• Flammability compliance (UL94 V-0)

The A3B-26PA-2DS(51) meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the substitute part carries Active status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The A3B-26PA-2DS(51) is the qualified substitute for the obsolete A3B-26PA-2DS(71). Both parts share identical electrical, mechanical, and thermal specifications within the A3 series rectangular connector family.

Selection of the A3B-26PA-2DS(51) is supported by:

• Identical connector architecture and pin configuration
• Matching electrical performance (1A, 200VAC)
• Equivalent thermal operating range (-55°C ~ 85°C)
• Identical material compliance (UL94 V-0 flammability rating)
• Active product status ensuring supply availability
• RoHS compliance certification on the substitute part

The substitute part is packaged in Bulk format, compared to the original part's unspecified packaging. This distinction does not affect functional compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the A3B-26PA-2DS(51) be used as a direct replacement for the A3B-26PA-2DS(71)?
