Substitute Part Grouping Explanation

Substitute parts for the A3-24DA-2SV are grouped based on strict electrical and mechanical compatibility criteria. All substitutes maintain the following core parameters: 24-position receptacle configuration, 0.079" (2.00mm) pitch, 2-row layout with 0.079" row spacing, surface mount solder termination, push-pull fastening, and gold-plated mating contacts. These parameters define the physical and electrical interchangeability of the connector within board-to-board or cable applications.

Substitutes are differentiated by secondary parameters including contact finish thickness, insulation material, operating temperature range, current rating, voltage rating, and packaging format. The A3-24DA-2SV(71) represents a direct variant with improved RoHS3 compliance. The 3M 1502 series (150224-2000-RB-WD, 150224-2020-RB, 150224-2020-RB-WD) and Amphenol ICC Minitek® 2.00mm series (55510-024LF, 55510-024TRLF, 55510-124LF, 55510-324LF) provide functionally equivalent alternatives with enhanced operating temperature ranges and higher current ratings. The Samtec Tiger Eye™ SMM series (SMM-112-02-F-D-K-TR, SMM-112-02-H-D) offers superior electrical performance with higher current capacity and voltage ratings.

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): The A3-24DA-2SV(71) is the primary substitute, offering identical electrical and mechanical specifications with active product status and ROHS3 compliance. This part is sourced from the same manufacturer and maintains all original design parameters.

3M 1502 Series Substitutes: The 150224-2000-RB-WD, 150224-2020-RB, and 150224-2020-RB-WD are suitable for applications requiring enhanced operating temperature range (-55°C to 105°C) and higher voltage rating (500VDC). These parts maintain 1A current rating and are RoHS compliant. Packaging options include Tape & Reel and Tray formats for production flexibility.

Frequently Asked Questions (FAQ)

Q: Can the A3-24DA-2SV be directly replaced with A3-24DA-2SV(71)? A: Yes. The A3-24DA-2SV(71) is a direct variant with identical electrical and mechanical specifications. The primary difference is active product status and ROHS3 compliance. Packaging is supplied in Tube format.

Q: What are the key differences between Hirose and 3M substitutes? A: The 3M 1502 series (150224 base number) maintains the 1A current rating but offers higher voltage rating (500VDC versus 200VAC) and extended operating temperature range (-55°C to 105°C). Both manufacturers provide RoHS-compliant options.

Q: Are Amphenol ICC Minitek® parts compatible with the original A3-24DA-2SV? A: Yes, for applications within the original specifications. The Minitek® series (55510 base number) provides identical pitch, position count, and mounting type. The 2A current rating and 125°C maximum operating temperature exceed original specifications, making these parts suitable for higher-performance applications.

Q: What is the advantage of Samtec Tiger Eye™ SMM connectors? A: The SMM series provides significantly higher current capacity (3.2A per contact) and voltage rating (350VAC) compared to the original 1A/200VAC specification. Beryllium Copper contacts and Liquid Crystal Polymer insulation enhance reliability in demanding environments. These parts are ROHS3 compliant.

Q: How do packaging formats affect part selection? A: Packaging format (Tube, Tape & Reel, Tray) impacts production workflow and handling. Tape & Reel format is optimized for automated assembly. Tube packaging is suitable for manual handling and lower-volume applications. Tray format provides intermediate handling capability. Electrical and mechanical performance is independent of packaging format.

Q: Are all substitute parts RoHS compliant? A: The original A3-24DA-2SV is RoHS non-compliant. All listed substitutes are RoHS compliant (either RoHS3 or standard RoHS). The A3-24DA-2SV(71), SMM-112-02-F-D-K-TR, and SMM-112-02-H-D are ROHS3 compliant. The 3M and Amphenol ICC parts are RoHS compliant.

Q: Can substitutes be used interchangeably in existing designs? A: Substitutes with identical pitch (0.079"/2.00mm), position count (24), row configuration (2 rows), and mounting type (surface mount) are mechanically interchangeable. Electrical interchangeability depends on application voltage and current requirements. Designs operating at original specifications (1A, 200VAC) are compatible with all listed substitutes.
