Harwin M20-9713045 Equivalent & Substitute Parts

Part Overview

The Harwin M20-9713045 is a rectangular connector header featuring a right-angle, through-hole mount configuration with 30 positions at 0.100" (2.54mm) pitch. This connector is designed for board-to-board or cable applications with unshrouded, male pin contacts and solder termination. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Harwin M20-9713045 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 30
• Number of Rows: 1
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant or RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts meet these core electrical and mechanical requirements. Variations in contact length, insulation height, contact finish thickness, and operating temperature ranges are within acceptable tolerances for this connector category and do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete Harwin M20-9713045. Selection among substitutes should be based on the following criteria:

Molex 0022288300 and 0022288302: Both are active KK254 series connectors with ROHS3 compliance. The 0022288300 features tin mating contact finish, while 0022288302 provides gold mating contact finish. Both are suitable for general-purpose, automotive, medical, and telecommunications applications.

Amphenol ICC 77315-824-30LF: Active BERGSTIK® series connector with RoHS compliance and extended operating temperature range (-65°C ~ 125°C). Phosphor bronze contact material and gold or GXT™ finish provide enhanced durability. Suitable for applications requiring wider temperature performance.

Preci-Dip 890-70-030-20-002101: Active series 890 connector with ROHS3 compliance, gold contact finish on both mating and post surfaces, and 150VDC voltage rating specification. Extended operating temperature range (-55°C ~ 125°C) and brass contact material match the original Harwin design most closely.

For direct replacement with minimal design modification, the Preci-Dip 890-70-030-20-002101 offers the closest dimensional and material alignment to the original part.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0022288300 as a direct substitute for the Harwin M20-9713045?

A: Yes. The Molex 0022288300 meets all critical substitution parameters: 30-position, 2.54mm pitch, through-hole right-angle mount, solder termination, and UL94 V-0 flammability rating. The tin mating contact finish differs from the original gold finish but remains functionally compatible for standard applications.

Q: What is the difference between Molex 0022288300 and 0022288302?

A: Both are KK254 series connectors with identical mechanical and electrical specifications. The primary difference is the mating contact finish: 0022288300 uses tin finish, while 0022288302 uses gold finish. Selection depends on application requirements for contact corrosion resistance and conductivity.

Q: Why does the Amphenol ICC 77315-824-30LF have a different operating temperature range?

A: The Amphenol ICC 77315-824-30LF is rated for -65°C ~ 125°C, compared to the original -40°C ~ 105°C. This extended range reflects the BERGSTIK® series design specifications and does not prevent substitution. Applications operating within the original temperature range remain fully compatible.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts meet RoHS compliance requirements. Three parts carry ROHS3 certification (Molex 0022288300, Molex 0022288302, and Preci-Dip 890-70-030-20-002101), while the Amphenol ICC 77315-824-30LF carries RoHS Compliant status. All are suitable for applications requiring RoHS compliance.

Q: What is the significance of the contact length variations shown in the parameter comparison?

A: Contact length variations (ranging from 0.244" to 0.276" for mating contacts) are within acceptable tolerances for 2.54mm pitch header connectors and do not affect mating compatibility. These variations reflect different manufacturer design approaches and do not prevent functional substitution in standard board-to-board applications.

Q: Which substitute part most closely matches the original Harwin M20-9713045?

A: The Preci-Dip 890-70-030-20-002101 provides the closest alignment, with matching contact length (0.276" mating, 0.118" post), insulation height (0.100"), brass contact material, and gold finish on both mating and post surfaces. This part requires minimal design modification for direct replacement.

Q: Can I mix substitute parts in the same design?

A: All substitute parts are mechanically and electrically compatible with each other due to standardized 2.54mm pitch and push-pull fastening. However, for consistency and supply chain management, using a single substitute part across a design is recommended.
