Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0537280262 is determined by the following critical parameters that must remain consistent or compatible:

Fixed Substitution Criteria:

• Connector Type: Header (male pin contact type)
• Number of Positions: 2
• Number of Rows: 2
• Shrouding: Shrouded - 4 Wall
• Mounting Type: Through Hole
• Termination: Kinked Pin, Solder
• Contact Shape: Square
• Contact Material: Copper Alloy
• Insulation Material: Polyamide (PA), Nylon, Glass Filled
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variable Parameters Allowing Substitution:

• Row Spacing - Mating: 0.177" (4.50mm) in the original part; substitute parts may have different row spacing if the application permits
• Fastening Type: Latch Lock (original); substitutes may use alternative fastening mechanisms such as Latch Holder
• Contact Finish Thickness - Mating: 39.4µin (1.00µm) (original); substitutes may have 50.0µin (1.27µm) or other thicknesses
• Insulation Color: Red (original); substitutes may differ
• Operating Temperature: -40°C ~ 105°C (original); substitutes with equivalent or broader ranges are acceptable
• Voltage Rating: 600V (original); substitutes with equal or higher ratings are acceptable

The Molex 1510481203 qualifies as a substitute based on matching all fixed criteria while maintaining compatibility in variable parameters.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1510481203 is the manufacturer-recommended substitute for the obsolete Molex 0537280262. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory continuity in applications requiring these standards.

The primary design difference is row spacing: the original part specifies 0.177" (4.50mm), while the substitute provides 0.256" (6.50mm). This increased spacing must be evaluated against PCB layout constraints and mating connector specifications. The substitute's active product status ensures ongoing availability and supply chain stability compared to the obsolete original part.

Both components share identical contact dimensions, insulation height, and termination method, supporting direct mechanical and electrical compatibility in applications where the increased row spacing is accommodated by the design.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1510481203 be used as a direct replacement for the 0537280262?

A: The 1510481203 is electrically and mechanically compatible with the 0537280262 in applications where the row spacing difference of 0.079" (2.00mm) does not conflict with PCB layout or mating connector positioning. Both parts share identical contact geometry, termination method, and insulation specifications.

Q: What is the significance of the row spacing difference?

A: Row spacing determines the physical distance between the two rows of connector positions. The original part uses 0.177" (4.50mm) spacing, while the substitute uses 0.256" (6.50mm). This difference affects PCB footprint design and compatibility with mating connectors. Verify that the mating connector or cable assembly accommodates the substitute's spacing before implementation.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. No compliance gaps exist between the original and substitute components.

Q: Why is the original part obsolete?

A: The 0537280262 is classified as obsolete by the manufacturer. The 1510481203 represents the current active product line for equivalent 2-position shrouded header connectors with through-hole mounting.

Q: What is the difference between Latch Lock and Latch Holder fastening?

A: Both fastening types provide mechanical retention of mated connectors. Latch Lock and Latch Holder are functionally equivalent retention mechanisms used in Molex connector designs. Selection depends on the mating connector type and application requirements.

Q: Does insulation color affect electrical performance?

A: Insulation color (red on the original, yellow on the substitute) is a visual identifier only and does not affect electrical or mechanical performance. Color selection is typically based on manufacturing standards or application conventions.
