Molex 0428205232 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0428205232 is a shrouded header connector from the Mini-Fit Sr 42820 series, designed for through-hole, right-angle board-to-cable/wire applications. This 5-position connector features male blade contacts with 0.394" (10.00mm) pitch spacing and is widely used in automotive, industrial, medical, and telecommunications applications. The part maintains active product status with full RoHS3 compliance and UL94 V-0 material flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility while maintaining design integrity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0428205232 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Type: Header with Male Blade contacts
• Position Configuration: 5 positions, 1 row
• Pitch Spacing: 0.394" (10.00mm) mating pitch
• Mounting & Orientation: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall configuration
• Termination Method: Solder termination
• Contact Material & Finish: Copper Zirconium Alloy with Tin finish
• Insulation Specifications: Polyamide (PA46), Nylon 4/6, Glass Filled; Black color
• Compliance: RoHS3 Compliant; UL94 V-0 flammability rating

The substitute part Molex 0428205212 maintains equivalence across all critical parameters. The primary distinction is the Contact Length - Post specification: 0.138" (4.60mm) versus 0.201" (5.11mm) in the primary part. This dimensional variance affects board-level mounting depth and must be evaluated against specific PCB design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part (0428205232) and substitute part (0428205212) maintain active product status with identical compliance certifications: RoHS3 compliance and UL94 V-0 material flammability rating. Both parts are sourced from Molex within the same Mini-Fit Sr 42820 series, ensuring design consistency and supply chain reliability.

The critical selection factor is the Contact Length - Post dimension. The primary part features a 0.201" (5.11mm) post length, while the substitute provides a shorter 0.138" (4.60mm) post length. This difference directly impacts PCB mounting depth and solder joint geometry. Selection between these parts must be based on specific PCB thickness, component density, and through-hole depth requirements in the target application.

Both parts are suitable for automotive, industrial, medical, and telecommunications applications where RoHS3 compliance and UL94 V-0 flammability ratings are required. Inventory availability should also be considered: the substitute part (0428205212) currently maintains higher stock levels (1326 pcs) compared to the primary part (922 pcs).

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 0428205232 and 0428205212?

A: The primary difference is the Contact Length - Post specification. The 0428205232 features a 0.201" (5.11mm) post length, while the 0428205212 features a 0.138" (4.60mm) post length. All other electrical and mechanical parameters remain identical.

Q: Are these parts electrically interchangeable?

A: Yes. Both parts share identical contact material (Copper Zirconium Alloy), contact finish (Tin at 100.0µin thickness), pitch spacing (0.394"/10.00mm), and connector configuration (5-position, 1-row, shrouded header). Electrical performance is equivalent.

Q: Does the post length difference affect mechanical compatibility?

A: The post length difference affects PCB mounting depth and solder joint formation. The shorter post length of the 0428205212 reduces overall board-level stack height. Compatibility depends on specific PCB design parameters, including board thickness and available mounting depth.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 0428205232 and 0428205212 are ROHS3 Compliant with UL94 V-0 material flammability rating, meeting regulatory requirements for automotive, industrial, medical, and telecommunications applications.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use the 0428205212 as a direct replacement in existing designs?

A: Direct replacement is possible only if the PCB design accommodates the shorter 0.138" (4.60mm) post length. If the original design requires the 0.201" (5.11mm) post length for proper solder joint formation or component clearance, the 0428205212 is not suitable without PCB modification.
