Harwin M20-9711446 Equivalent & Substitute Parts

Part Overview

The Harwin M20-9711446 is a rectangular connector header, right-angle configuration, with 14 positions at 0.100" (2.54mm) pitch. This through-hole, solder-terminated component is designed for board-to-board or cable connections with male pin contacts. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility across the 14-position, 2.54mm pitch standard while accommodating variations in contact materials, finishes, and insulation specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Harwin M20-9711446 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 14 — exact match required
• Number of Rows: 1 — exact match required
• Mounting Type: Through Hole, Right Angle — exact match required
• Contact Type: Male Pin — exact match required
• Termination: Solder — exact match required
• Fastening Type: Push-Pull — exact match required
• Material Flammability Rating: UL94 V-0 — minimum requirement
• RoHS Status: ROHS3 Compliant — minimum requirement
• Moisture Sensitivity Level: 1 (Unlimited) — minimum requirement

All three substitute parts (Molex 0022288140, Molex 0022288142, and Amphenol ICC 77315-124-14LF) meet these core substitution criteria. Variations in contact finish, contact material, insulation material composition, and contact length dimensions are within acceptable tolerances for this connector category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, addressing the obsolescence of the Harwin M20-9711446. Selection among substitutes should be based on the following factors:

Molex 0022288140 and 0022288142 (KK254 Series): Both parts are from the Molex KK254 series and maintain tin contact finish on mating surfaces (0022288140) or gold contact finish (0022288142). These parts are ROHS3 compliant and carry unlimited moisture sensitivity rating. The primary distinction between these two Molex options is the mating contact finish: tin versus gold. Both are suitable for general-purpose, automotive, medical, and telecommunications applications.

Amphenol ICC 77315-124-14LF (BERGSTIK® Series): This part features phosphor bronze contact material with gold or gold GXT™ mating finish and operates across an extended temperature range (-65°C ~ 125°C) compared to the original Harwin part. The Amphenol ICC part is RoHS compliant and carries the same unlimited moisture sensitivity rating. This option provides enhanced thermal performance for applications requiring operation beyond the original -40°C ~ 105°C specification.

All three substitutes maintain the critical 14-position, 2.54mm pitch, through-hole right-angle configuration with push-pull fastening and solder termination. Contact finish variations (tin versus gold) do not affect mechanical interchangeability but may influence corrosion resistance and contact reliability in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can Molex 0022288140 and 0022288142 be used interchangeably with the Harwin M20-9711446?

A: Yes. Both Molex parts meet all critical substitution parameters: 14 positions, 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, and push-pull fastening. The primary difference between the two Molex options is contact finish (tin versus gold), which does not affect mechanical compatibility.

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

A: Tin contact finish (Molex 0022288140) provides cost-effective performance for standard applications. Gold contact finish (Molex 0022288142 and Amphenol ICC 77315-124-14LF) offers enhanced corrosion resistance and is preferred for applications with extended shelf life or exposure to corrosive environments.

Q: Is the Amphenol ICC 77315-124-14LF suitable for high-temperature applications?

A: The Amphenol ICC part operates from -65°C ~ 125°C, extending the upper temperature limit by 20°C compared to the original Harwin part (-40°C ~ 105°C). This makes it suitable for applications requiring operation at elevated temperatures within the specified range.

Q: Are all substitute parts RoHS compliant?

A: Yes. Molex 0022288140 and 0022288142 are ROHS3 compliant. Amphenol ICC 77315-124-14LF is RoHS compliant. All three parts meet regulatory requirements for lead-free manufacturing.

Q: What is the moisture sensitivity level for these connectors?

A: All substitute parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these connectors be cut or separated into smaller configurations?

A: The Harwin M20-9711446 is specified as cuttable. The Molex and Amphenol ICC substitutes are specified as breakaway, which provides similar functionality for creating custom configurations. Consult manufacturer documentation for specific cutting or separation procedures.

Q: What is the current rating for these connectors?

A: The Harwin M20-9711446 and Amphenol ICC 77315-124-14LF are rated at 3A per contact. Current rating is not specified for the Molex 0022288140 and 0022288142; consult Molex technical documentation for detailed electrical specifications.
