Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core electrical and mechanical parameters. The following parameters establish the substitution envelope for the Preci-Dip 890-70-010-20-002101:

Critical Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Height: 0.100" (2.54mm)
• Contact Shape: Square
• Contact Material: Brass
• Current Rating: 3A minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The Harwin Inc. M20-9961045 and M20-9961046 connectors satisfy all critical matching parameters. Both parts are cuttable header variants within the M20 series, maintaining identical pitch, position count, row configuration, mounting orientation, and termination method. Both achieve UL94 V-0 flammability compliance and ROHS3 compliance. Variations in contact finish (gold versus tin) and operating temperature range represent secondary parameter differences that do not preclude substitution within the defined electrical and mechanical framework.

Parameter Comparison

Engineering Selection Recommendations

Preci-Dip 890-70-010-20-002101 remains the primary specification when the full operating temperature range of -55°C to 125°C is required and when gold contact finish is mandated for corrosion resistance in high-reliability applications. This part maintains Active product status with 800 units in stock.

Harwin M20-9961045 serves as a functional substitute when operating temperature requirements fall within -40°C to 105°C and when gold contact finish is acceptable. The cuttable header feature provides design flexibility for applications requiring custom position counts. This part maintains Active product status with 2621 units in stock.

Harwin M20-9961046 serves as a functional substitute when operating temperature requirements fall within -40°C to 105°C and when tin contact finish is acceptable for cost optimization or when tin plating is specified for wave soldering processes. The cuttable header feature provides design flexibility for applications requiring custom position counts. This part maintains Active product status with 2034 units in stock.

All three parts achieve ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Selection between substitute parts should be based on contact finish requirements, operating temperature envelope, and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M20-9961045 or M20-9961046 be used as a direct replacement for the Preci-Dip 890-70-010-20-002101 in all applications?

A: The Harwin parts are functionally compatible when the application operating temperature does not exceed 105°C. The Preci-Dip part supports extended temperature operation to 125°C. Applications requiring the full -55°C to 125°C range must use the Preci-Dip part. Contact finish differences (gold versus tin) may affect corrosion resistance in specific environments.

Q: What is the significance of the "cuttable" feature on the Harwin M20 series headers?

A: The cuttable feature allows the header to be mechanically separated into smaller position counts after manufacturing, providing design flexibility. This feature does not affect compatibility with standard 10-position applications.

Q: Are there differences in contact mating length between these parts?

A: Yes. The Preci-Dip 890-70-010-20-002101 has a contact mating length of 0.276" (7.00mm), while both Harwin M20 parts have 0.240" (6.10mm) mating length. This 0.036" difference may affect mating depth with certain connector housings. Verify housing compatibility before substitution.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, UL94 V-0 rated, and classified as MSL 1 (Unlimited moisture sensitivity). All carry EAR99 ECCN classification and 8536.69.4040 HTSUS code. Compliance profiles are equivalent.

Q: What is the difference between gold and tin contact finishes?

A: Gold finish (Preci-Dip and M20-9961045) provides superior corrosion resistance and is preferred for high-reliability applications. Tin finish (M20-9961046) is suitable for standard applications and is compatible with wave soldering processes. Contact finish selection depends on environmental exposure and manufacturing process requirements.

Q: Is voltage rating specified for the Harwin substitute parts?

A: Voltage rating is not specified in the provided data for the Harwin M20-9961045 and M20-9961046 parts. The Preci-Dip part is rated for 150VDC. Verify voltage requirements with the manufacturer before substitution in high-voltage applications.
