Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5535512-3 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters that must remain consistent across equivalent parts:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (24)
• Pitch configuration (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact material (Phosphor Bronze)
• Contact shape (Square)
• Flammability rating (UL94 V-0)

Allowable Variation Parameters:

• Contact finish (Gold vs. Tin)
• Contact finish thickness
• Insulation material composition
• Insulation height (within tolerance)
• Contact length - post (within tolerance)
• Operating temperature range (may differ)
• Current rating (may differ)
• Voltage rating (may differ)

The Harwin Inc. M20-7881246 connector qualifies as a substitute part based on matching all critical parameters while allowing for specified variations in contact finish and electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 5535512-3 and Harwin M20-7881246 connectors maintain active product status and comply with RoHS requirements, ensuring long-term availability and environmental compliance. The selection between these parts should be based on specific application requirements:

TE Connectivity 5535512-3 Selection Criteria:

• Applications requiring extended operating temperature range (-55°C to 125°C)
• Systems where gold-plated mating contacts are specified for enhanced corrosion resistance
• Designs with 2A current rating requirements
• AMPMODU Mod II series compatibility requirements

Harwin M20-7881246 Selection Criteria:

• Applications operating within -40°C to 105°C temperature range
• Systems where tin-plated contacts are acceptable
• Designs requiring higher current capacity (3A rating)
• Applications requiring specified voltage rating (1000V)
• Polyamide insulation material compatibility requirements

Both connectors feature identical mechanical pitch, row configuration, and push-pull fastening characteristics, ensuring physical and functional interchangeability within their respective operating parameter ranges. The primary differentiators are contact finish type, operating temperature range, current rating, and insulation material composition.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M20-7881246 be used as a direct replacement for the TE Connectivity 5535512-3?

A: The Harwin M20-7881246 is mechanically and functionally compatible with the TE Connectivity 5535512-3 for applications operating within the -40°C to 105°C temperature range. The primary differences are contact finish (tin vs. gold), current rating (3A vs. 2A), and insulation material. Applications requiring the extended temperature range of the TE part (-55°C to 125°C) or gold-plated contacts must use the original TE Connectivity part.

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

A: The TE Connectivity 5535512-3 features gold-plated mating contacts (30.0µin thickness), which provide superior corrosion resistance and lower contact resistance in low-signal applications. The Harwin M20-7881246 uses tin-plated mating contacts, which are suitable for general-purpose applications and provide adequate performance for standard interconnect requirements. Gold plating is typically specified for applications with stringent reliability requirements or exposure to corrosive environments.

Q: Are there any compatibility issues with PCB mounting between these two connectors?

A: Both connectors use identical 0.100" (2.54mm) pitch through-hole, right-angle mounting configurations. Minor dimensional variations exist in insulation height (0.238" vs. 0.232") and contact post length (0.115" vs. 0.118"), but these differences are within standard manufacturing tolerances and do not affect PCB mounting compatibility. Solder pad layouts designed for either connector will accommodate both parts.

Q: What are the implications of the different operating temperature ranges?

A: The TE Connectivity 5535512-3 operates from -55°C to 125°C, while the Harwin M20-7881246 operates from -40°C to 105°C. Applications requiring operation at temperatures below -40°C or above 105°C must use the TE Connectivity part. For applications within the overlapping range (-40°C to 105°C), either connector is suitable from a temperature perspective.

Q: How do the current ratings affect component selection?

A: The TE Connectivity 5535512-3 is rated for 2A per contact, while the Harwin M20-7881246 is rated for 3A per contact. Applications requiring current levels between 2A and 3A per contact must use the Harwin part. Applications with current requirements at or below 2A per contact can use either connector.

Q: What is the difference in insulation material, and does it affect performance?

A: The TE Connectivity 5535512-3 uses polyester with glass filling, while the Harwin M20-7881246 uses polyamide (PA6T) nylon 6T. Both materials meet UL94 V-0 flammability requirements and provide adequate insulation properties for standard applications. Material selection may be relevant for applications with specific chemical exposure or mechanical stress requirements.

Q: Are both connectors RoHS compliant?

A: Yes, both connectors are RoHS compliant. The TE Connectivity 5535512-3 is RoHS Compliant, and the Harwin M20-7881246 is ROHS3 Compliant. Both meet current environmental regulations for lead-free and restricted substance requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both connectors have an MSL rating of 1 (Unlimited), indicating they have unlimited shelf life and do not require special moisture control during storage or handling. This simplifies inventory management and reduces the risk of moisture-related failures.
