Substitute Part Grouping Explanation

Substitution of the 150224-2000-TH-WD is determined by the following critical parameters:

24-position configuration with 0.079" (2.00mm) pitch and 2-row layout
Surface mount solder termination with push-pull fastening
Gold-plated mating contacts
1A current and 500VDC voltage ratings
UL94 V-0 flammability compliance
Female socket contact type for board-to-board or cable applications

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in contact finish thickness, insulation material, operating temperature range, and product status are noted but do not prevent functional substitution within the specified parameter envelope.

Engineering Selection Recommendations

Primary Substitute: 3M 150224-2000-RB-WD

The 150224-2000-RB-WD is the direct equivalent from 3M's active product line. This part maintains identical electrical and mechanical specifications to the obsolete 150224-2000-TH-WD, including pitch, position count, current and voltage ratings, and operating temperature range. The primary distinction is product status (Active vs. Obsolete) and RoHS compliance (RoHS Compliant vs. non-compliant). Packaging is provided as Tape & Reel (TR) for automated assembly. This part is recommended as the first choice for direct replacement.

Secondary Substitutes: Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71)

Both Hirose parts maintain the core 24-position, 0.079" pitch, surface mount, push-pull configuration with gold-plated mating contacts and 1A current rating. These parts are active products with RoHS compliance. The A3A-24DA-2SV(71) includes a board guide feature. Key differences include:

Operating temperature range reduced to -55°C ~ 85°C (versus -55°C ~ 105°C for the 3M part)
Voltage rating of 200VAC (versus 500VDC for the 3M part)
Insulation height of 0.165" (4.20mm) versus 0.183" (4.65mm)
Insulation material is Polyphenylene Sulfide (PPS) versus Thermoplastic
Contact material is Phosphor Bronze versus Copper Alloy

These Hirose parts are suitable for applications where the reduced operating temperature and voltage specifications are acceptable and where the mechanical envelope differences do not conflict with board layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 150224-2000-RB-WD directly replace the obsolete 150224-2000-TH-WD?

A: Yes. The 150224-2000-RB-WD maintains identical electrical and mechanical specifications, including 24-position configuration, 0.079" pitch, 1A current rating, 500VDC voltage rating, and -55°C to 105°C operating temperature. The primary difference is product status and RoHS compliance. Packaging is Tape & Reel (TR) instead of bulk.

Q: What are the key differences between the 3M and Hirose substitute parts?

A: The 3M 150224-2000-RB-WD maintains the full 500VDC voltage rating and -55°C to 105°C operating temperature. The Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71) operate at 200VAC and -55°C to 85°C. Insulation height differs: 3M parts are 0.183" (4.65mm), Hirose parts are 0.165" (4.20mm). Contact material differs: 3M uses Copper Alloy, Hirose uses Phosphor Bronze.

Q: Are the Hirose parts suitable for high-voltage applications?

A: No. The Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71) are rated for 200VAC, which is significantly lower than the 500VDC rating of the 3M parts. Application of these Hirose parts to 500VDC circuits exceeds their voltage specification.

Q: What is the difference between A3-24DA-2SV(71) and A3A-24DA-2SV(71)?

A: Both parts are electrically and mechanically identical. The A3A-24DA-2SV(71) includes a board guide feature. Selection between these parts depends on whether the board guide is required for mechanical alignment in the application.

Q: Are all substitute parts RoHS compliant?

A: The 150224-2000-RB-WD is RoHS Compliant. The Hirose A3-24DA-2SV(71) is ROHS3 Compliant. The Hirose A3A-24DA-2SV(71) is RoHS Compliant. The original 150224-2000-TH-WD is RoHS non-compliant.

Q: What packaging options are available for these parts?

A: The 150224-2000-RB-WD is supplied in Tape & Reel (TR). The Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71) are supplied in Tube packaging.

Q: Can these connectors be used interchangeably in the same PCB design?

A: The 3M parts (150224-2000-TH-WD and 150224-2000-RB-WD) are directly interchangeable due to identical mechanical and electrical specifications. The Hirose parts have a reduced insulation height (0.165" versus 0.183"), which may affect PCB footprint compatibility and mating stack height. Board layout verification is necessary before substitution with Hirose parts.
