Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 9-2178711-0 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (20)
• Pitch - mating (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Voltage rating (100VDC)
• Fastening type (Push-Pull)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount)
• Termination method (Solder)
• Contact type (Forked)
• Style (Board to Board or Cable)
• Insulation height (0.209" / 5.30mm)
• Series (Micro-MaTch)

Regulatory Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL 1 - Unlimited)

The substitute parts 2-188275-0 and 9-188275-0 maintain full equivalence across all critical electrical and mechanical parameters. Both are active products within the same Micro-MaTch series, differ only in packaging format (Cut Tape versus Tape & Reel), and provide enhanced operating temperature ranges and improved flammability ratings compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 2-188275-0 and 9-188275-0 provide direct functional equivalence to the obsolete 9-2178711-0 across all critical electrical and mechanical parameters. Selection between the two active alternatives is determined by packaging requirements:

2-188275-0 (Cut Tape Packaging): Suitable for applications requiring manual component handling, lower volume production runs, or inventory management where individual unit access is prioritized.

9-188275-0 (Tape & Reel Packaging): Suitable for automated pick-and-place assembly processes and high-volume production environments. This variant includes Pick and Place feature designation.

Both substitute parts offer enhanced specifications compared to the original obsolete part, including extended operating temperature range (-40°C to 105°C versus -30°C to 85°C) and UL94 V-0 flammability certification. The contact material upgrade from Brass to Phosphor Bronze in the substitute parts provides improved mechanical durability and contact reliability. All three parts maintain identical electrical performance at 100VDC and preserve the same 0.100" (2.54mm) pitch geometry required for Micro-MaTch series compatibility.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 2-188275-0 and 9-188275-0 electrically identical to the obsolete 9-2178711-0?

A: Yes. Both substitute parts maintain identical electrical specifications including 20-position configuration, 0.100" (2.54mm) pitch, 100VDC voltage rating, and Push-Pull fastening type. The electrical performance is fully equivalent for board-to-board and cable interconnection applications.

Q: What is the difference between the two substitute parts?

A: The primary difference is packaging format. Part 2-188275-0 is supplied in Cut Tape (CT) format for manual handling, while part 9-188275-0 is supplied in Tape & Reel (TR) format optimized for automated assembly equipment. Both parts are electrically and mechanically identical.

Q: Can I use these substitute parts in existing designs without PCB layout modifications?

A: Yes. The substitute parts maintain identical mechanical dimensions, pitch spacing (0.100" / 2.54mm), insulation height (0.209" / 5.30mm), and surface mount termination method. PCB footprints and assembly processes require no modification.

Q: What are the advantages of the substitute parts over the original 9-2178711-0?

A: The substitute parts offer extended operating temperature range (-40°C to 105°C versus -30°C to 85°C), UL94 V-0 flammability certification, and upgraded contact material (Phosphor Bronze versus Brass) for improved mechanical durability and contact reliability. Both remain ROHS3 compliant with MSL 1 rating.

Q: Are there any compatibility concerns with mating connectors?

A: No. The substitute parts maintain full mechanical and electrical compatibility with all Micro-MaTch series mating connectors designed for 0.100" (2.54mm) pitch, 20-position receptacle configurations. The Push-Pull fastening mechanism and contact geometry are unchanged.

Q: Which substitute part should I select for high-volume production?

A: Part 9-188275-0 (Tape & Reel format) is recommended for high-volume production environments utilizing automated pick-and-place assembly equipment. This packaging format optimizes component handling efficiency and assembly line throughput.

Q: Are both substitute parts currently in active production?

A: Yes. Both 2-188275-0 and 9-188275-0 are classified as Active products with current inventory availability (2800 and 2900 units respectively), ensuring long-term supply continuity and design lifecycle support.
