Amphenol ICC 69157-124 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 69157-124 is an active rectangular connector header designed for through-hole board-to-board applications. This 24-position, 2-row connector operates at 0.100" (2.54mm) pitch and features male pins with solder termination and push-pull fastening. The connector is constructed with phosphor bronze contacts finished in gold or GXT™ and housed in a black, unshrouded polyamide insulation body rated UL94 V-0. With 989 pieces in current stock, this connector serves as a standard interconnect solution for embedded systems, industrial control, and consumer electronics requiring reliable through-hole mounting. Equivalent substitute parts are identified to provide procurement flexibility and supply chain alternatives while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 69157-124 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Contact type: Male pin
• Number of positions: 24
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Fastening type: Push-pull
• Termination: Solder

Mechanical Compatibility:

• Connector type: Header
• Mounting type: Through hole
• Contact shape: Square
• Shrouding: Unshrouded
• Style: Board to board

Environmental & Regulatory:

• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The Harwin Inc. M20-9761246 meets all critical electrical and mechanical parameters, establishing it as a direct functional equivalent. Both connectors operate at identical pitch spacing, position count, and row configuration, enabling direct PCB footprint compatibility. Both feature push-pull fastening, solder termination, and unshrouded square-pin construction. Both achieve UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 69157-124 and Harwin Inc. M20-9761246 are active products with established supply availability. The Amphenol ICC connector maintains RoHS non-compliant status, while the Harwin equivalent achieves ROHS3 compliance. For applications requiring RoHS3 compliance, the Harwin M20-9761246 is the appropriate selection. For legacy systems or applications without RoHS requirements, either connector is functionally equivalent.

Contact finish differs between the two connectors: the Amphenol ICC uses gold or GXT™ finish on phosphor bronze contacts, while the Harwin uses tin finish on brass contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for standard through-hole applications. Contact length specifications vary slightly between the two connectors, with the Harwin M20-9761246 providing marginally longer mating and post contact lengths. These dimensional differences do not affect PCB footprint compatibility or standard mating operations.

The Harwin M20-9761246 offers cuttable header functionality, providing additional design flexibility for applications requiring custom pin configurations. Both connectors support identical electrical ratings and environmental classifications, including UL94 V-0 flammability and MSL 1 moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Are the Amphenol ICC 69157-124 and Harwin M20-9761246 directly interchangeable on the same PCB?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (24), row configuration (2 rows), and row spacing (0.100" / 2.54mm). PCB footprints designed for either connector are compatible with the other. Both feature square-pin male contacts with solder termination and push-pull fastening.

Q: What is the difference in contact finish between these connectors?

A: The Amphenol ICC 69157-124 uses gold or GXT™ finish on phosphor bronze contacts. The Harwin M20-9761246 uses tin finish on brass contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for standard through-hole applications. Contact finish selection depends on application-specific requirements for corrosion resistance, contact resistance, or cost optimization.

Q: Does the difference in overall contact length affect compatibility?

A: No. The Amphenol ICC 69157-124 has an overall contact length of 0.410" (10.41mm), while the Harwin M20-9761246 measures 0.452" (11.48mm). This dimensional variation does not affect PCB footprint compatibility or standard mating operations. Both connectors maintain identical insulation height (0.100" / 2.54mm) and pitch spacing, ensuring proper alignment and engagement with mating connectors.

Q: What is the significance of the Harwin M20-9761246 being ROHS3 compliant while the Amphenol ICC is RoHS non-compliant?

A: ROHS3 compliance indicates the Harwin connector meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials in electrical and electronic equipment. For applications subject to RoHS regulations or customer requirements, the Harwin M20-9761246 is the appropriate selection. For legacy systems or applications without RoHS mandates, the Amphenol ICC connector remains functionally equivalent.

Q: Can the Harwin M20-9761246 cuttable header feature be utilized in applications designed for the Amphenol ICC 69157-124?

A: Yes. The cuttable header feature of the Harwin M20-9761246 provides additional design flexibility, allowing custom pin configurations. This feature does not affect compatibility with applications designed for the standard Amphenol ICC connector. The cuttable functionality is an optional capability that may be utilized or disregarded depending on application requirements.

Q: Are both connectors rated for identical environmental conditions?

A: Both connectors achieve UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. The Harwin M20-9761246 specifies an operating temperature range of -40°C to 105°C. The Amphenol ICC 69157-124 does not specify an operating temperature range in the provided data. For applications requiring defined temperature specifications, the Harwin M20-9761246 provides explicit operating temperature limits.
