Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC/FPC connectors is determined by strict alignment of mechanical and electrical parameters. The following criteria establish compatibility:

Critical Parameters for Substitution:

• Number of positions (10)
• Pitch specification (1.00mm)
• Mounting type (Surface Mount)
• Height above board (5.05mm)
• FFC/FPC thickness (0.30mm)
• Connector orientation (Vertical - 1 Sided)
• Voltage rating (125V minimum)
• Current rating (0.5A minimum)
• Operating temperature range (must encompass -20°C to 80°C)
• Contact material (Phosphor Bronze)
• Housing material (Polyphenylene Sulfide)
• Flammability rating (UL94 V-0)

The Molex 0528081072 has one qualified substitute within the Easy-On 52808 series: the 0528081070. This substitute maintains identical mechanical dimensions, electrical ratings, and material specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528081070 is the direct substitute for the obsolete 0528081072. Selection of the 0528081070 is supported by the following factors:

Product Status: The 0528081070 maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The 0528081072 is obsolete and subject to discontinuation.

Regulatory Compliance: The 0528081070 is ROHS3 compliant, meeting current environmental and regulatory requirements. The 0528081072 is RoHS non-compliant, which may present compliance challenges in new designs or regulated markets.

Electrical and Mechanical Compatibility: Both connectors share identical specifications for positions, pitch, mounting type, height, thickness, voltage, current, contact material, housing material, and flammability rating. The operating temperature range of the 0528081070 (-20°C to 85°C) encompasses the original specification (-20°C to 80°C).

Contact Finish Difference: The 0528081072 features gold-plated contacts, while the 0528081070 uses tin bismuth finish. Both finishes are suitable for the specified electrical and environmental parameters. Contact finish selection depends on application-specific corrosion resistance and signal integrity requirements.

Packaging Consideration: The 0528081070 is supplied in Tape & Reel format, which is standard for high-volume production. The 0528081072 was supplied in bulk packaging. Tape & Reel packaging is compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528081070 directly replace the 0528081072 in existing designs?

A: Yes. The 0528081070 maintains identical mechanical dimensions, electrical ratings, and material specifications. Both connectors are 10-position, 1.00mm pitch, surface mount FFC/FPC connectors with matching height, thickness, voltage, current, and temperature operating ranges. The connectors are mechanically and electrically interchangeable.

Q: What is the difference between the contact finishes?

A: The 0528081072 uses gold plating, while the 0528081070 uses tin bismuth finish. Both finishes meet the specified electrical and environmental requirements. Gold finish typically offers superior corrosion resistance in harsh environments, while tin bismuth provides cost efficiency. Selection depends on application-specific environmental exposure and signal integrity criteria.

Q: Why is the 0528081070 in Tape & Reel packaging while the 0528081072 was bulk?

A: Tape & Reel is the standard packaging format for surface mount connectors in modern production environments. This packaging is optimized for automated pick-and-place assembly. Bulk packaging is no longer standard for active products in this category.

Q: Is the 0528081070 suitable for applications requiring RoHS compliance?

A: Yes. The 0528081070 is ROHS3 compliant. The 0528081072 is RoHS non-compliant. If your application or market requires RoHS compliance, the 0528081070 is the appropriate selection.

Q: Are there any temperature range differences between these connectors?

A: The 0528081072 operates from -20°C to 80°C. The 0528081070 operates from -20°C to 85°C. The 0528081070 has a slightly extended upper temperature limit, which is compatible with the original specification.

Q: What is the mating cycle rating for both connectors?

A: Both the 0528081072 and 0528081070 are rated for 10 mating cycles, indicating they are designed for applications with limited connector engagement/disengagement cycles.
