Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 890-80-010-20-002101 are qualified based on the following critical parameters that must match or remain compatible:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Type: Male Pin
• Contact Shape: Square
• Insulation Material: Polyamide (PA), Nylon, Glass Filled
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Compatible Variation Parameters:

• Contact Finish - Mating: Tin or Gold (both acceptable for 2.54mm pitch headers)
• Insulation Height: 0.098" to 0.100" (within tolerance for 2.54mm pitch)
• Contact Length - Mating: 0.240" to 0.276" (functional range for header applications)
• Contact Length - Post: 0.118" to 0.120" (within solder joint requirements)
• Operating Temperature: Substitute parts must support minimum -40°C to 105°C range

The three substitute parts listed below meet all mandatory parameters and are electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified equivalents for the 890-80-010-20-002101 based on compliance and certification alignment:

Molex 0022288100 (KK254 Series): This substitute maintains full electrical and mechanical compatibility with identical pitch, position count, and mounting configuration. The connector features breakaway capability and supports board-to-board or cable applications. ROHS3 compliance and UL94 V-0 flammability rating are confirmed. Inventory availability is 1608 units.

Harwin M20-9961045 (M20 Series, Gold Finish): This substitute provides equivalent functionality with cuttable header design and gold-plated mating contacts. The M20 series uses PA6T nylon insulation and maintains the required 3A current rating. Operating temperature range is -40°C to 105°C. ROHS3 compliance and UL94 V-0 rating are confirmed. Inventory availability is 2621 units.

Harwin M20-9961046 (M20 Series, Tin Finish): This substitute is functionally identical to M20-9961045 with tin-plated mating contacts instead of gold. The cuttable header design, PA6T nylon insulation, and 3A current rating are maintained. Operating temperature range is -40°C to 105°C. ROHS3 compliance and UL94 V-0 rating are confirmed. Inventory availability is 2034 units.

All substitute parts carry active product status and meet regulatory requirements for general-purpose, automotive, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022288100 be used as a direct replacement for the Preci-Dip 890-80-010-20-002101?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (10), row configuration (1), mounting type (through-hole right-angle), and termination method (solder). Both are UL94 V-0 rated and ROHS3 compliant. The Molex part includes breakaway capability, which is an additional feature that does not affect compatibility.

Q: What is the difference between the Harwin M20-9961045 and M20-9961046?

A: The primary difference is contact finish. M20-9961045 features gold-plated mating contacts, while M20-9961046 features tin-plated mating contacts. Both maintain identical mechanical dimensions, current rating (3A per contact), insulation material (PA6T nylon), and operating temperature range (-40°C to 105°C). Selection between these two depends on application requirements for contact finish performance.

Q: Are there any temperature operating range limitations when substituting with Harwin parts?

A: The Harwin M20 series (both M20-9961045 and M20-9961046) operate from -40°C to 105°C, which is narrower than the Preci-Dip 890-80-010-20-002101 range of -55°C to 125°C. If your application requires operation below -40°C or above 105°C, the Preci-Dip part is required. For applications within the -40°C to 105°C range, Harwin substitutes are fully compatible.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: Yes. All three substitute parts (Molex 0022288100, Harwin M20-9961045, and Harwin M20-9961046) are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability rating. Moisture sensitivity level is 1 (unlimited) for all parts. ECCN and HTSUS classifications are identical across all parts.

Q: What is the significance of the "cuttable" and "breakaway" features on substitute parts?

A: These features do not affect electrical or mechanical compatibility. "Cuttable" (Harwin M20 series) allows the header to be cut to reduce the number of positions if needed. "Breakaway" (Molex KK254) allows individual positions to be separated. Both features are optional design enhancements that provide application flexibility without compromising the standard 10-position configuration.

Q: Which substitute part has the highest inventory availability?

A: Harwin M20-9961045 has the highest inventory with 2621 units in stock, followed by M20-9961046 with 2034 units, and Molex 0022288100 with 1608 units. The original Preci-Dip 890-80-010-20-002101 has 785 units available.

Q: Are contact length variations between parts significant for PCB design?

A: Contact length variations are within functional tolerance for 2.54mm pitch header applications. The Preci-Dip part has mating contact length of 0.276" (7.00mm), while Molex and Harwin parts range from 0.240" to 0.244" (6.10mm to 6.20mm). These differences do not affect solder joint quality or electrical performance in standard through-hole PCB assembly processes.
