Substitute Part Grouping Explanation

Substitution of the Molex 0010899547 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 54
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Length - Mating: 0.240" (6.10mm)
• Contact Length - Post: 0.107" (2.71mm)
• Overall Contact Length: 0.437" (11.10mm)
• Insulation Height: 0.090" (2.29mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The Molex 0010897542 meets all mandatory matching parameters and qualifies as a direct substitute. The primary distinction is the transition from the obsolete C-Grid 8624 series to the active C-Grid 70280 series, with minor variations in insulation material composition and contact finish thickness specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0010897542 is the direct substitute for the obsolete Molex 0010899547. Both components maintain identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in existing designs.

The substitute part offers the advantage of active product status, ensuring long-term availability and continued manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for automotive, medical, telecommunications, and general purpose applications.

The transition from C-Grid 8624 to C-Grid 70280 series represents a product line evolution. The substitute incorporates Liquid Crystal Polymer (LCP) insulation material in place of polyester, providing enhanced thermal and mechanical properties. The contact finish thickness on the mating surface is increased from 5.00µin to 15.0µin, offering improved durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0010899547 and 0010897542 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including position count (54), row configuration (2 rows), pitch spacing (0.100"), contact lengths, and insulation height. They are direct mechanical substitutes.

Q: What is the primary reason for substitution?

A: The Molex 0010899547 is classified as obsolete. The Molex 0010897542 is the active equivalent from Molex, ensuring continued availability and manufacturing support.

Q: Are there differences in contact material between these parts?

A: Yes. The main part uses Phosphor Bronze contacts, while the substitute uses Copper Alloy contacts. Both materials are suitable for the specified applications and maintain the same contact finish specifications (gold mating surface, tin post finish).

Q: Does the insulation material change affect compatibility?

A: No. The substitute transitions from Polyester to Liquid Crystal Polymer (LCP) insulation, both glass-filled and rated UL94 V-0. This change enhances thermal stability and mechanical properties without affecting electrical or mechanical interface compatibility.

Q: Are both parts compliant with current regulations?

A: Yes. Both the Molex 0010899547 and 0010897542 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for the specified applications.

Q: What is the difference in contact finish thickness?

A: The main part specifies 5.00µin (0.127µm) gold finish on mating contacts, while the substitute specifies 15.0µin (0.38µm). The increased thickness on the substitute provides enhanced contact durability and wear resistance.

Q: Can I use the Molex 0010897542 as a direct replacement in existing designs?

A: Yes. The substitute maintains all critical mechanical and electrical parameters required for direct substitution in applications designed for the Molex 0010899547.
