Molex 0905003012 FFC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0905003012 is a 12-position flat flexible connector (FFC) designed for vertical mounting through-hole applications with 0.100" (2.54mm) pitch spacing. This connector features a slide lock mechanism and zero insertion force (ZIF) design, supporting up to 2.5A at 250V with operating temperatures from -40°C to 85°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FFC connectors is determined by the following critical parameters:

• Position count and pitch: Both the main part and substitute must maintain 12 positions at 0.100" (2.54mm) pitch to ensure mechanical and electrical compatibility with existing cable assemblies and PCB layouts.
• Mounting configuration: Through-hole mounting is required for both parts to maintain compatibility with existing PCB designs.
• Connector orientation: Vertical mounting is mandatory for both parts.
• Locking mechanism: Slide lock functionality must be present in the substitute to ensure secure cable retention.
• Zero insertion force (ZIF): This feature must be retained in the substitute for consistent mating performance.
• Contact material and finish: Phosphor bronze with tin finish ensures equivalent electrical performance and corrosion resistance.
• Termination method: Solder termination is required for both parts.
• Compliance standards: RoHS3 compliance and MSL 1 rating are maintained across both parts.

The TE Connectivity AMP Connectors 487925-9 meets these core substitution criteria. A key difference exists in the connector contact configuration: the main part features 2-sided vertical contacts, while the substitute features 1-sided vertical contacts. This difference reflects different cable assembly designs but maintains functional equivalence for standard FFC applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 487925-9 is the designated manufacturer-recommended substitute for the obsolete Molex 0905003012. Both parts maintain RoHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The substitute part carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete main part.

The primary design difference—1-sided versus 2-sided vertical contacts—reflects different cable assembly architectures. Selection between these parts depends on the specific cable assembly design used in the application. The substitute maintains all critical electrical and mechanical parameters: 12-position configuration, 2.54mm pitch, through-hole mounting, slide lock mechanism, and ZIF design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 487925-9 directly replace the Molex 0905003012 in existing designs?

A: Direct replacement depends on the cable assembly design. Both parts share identical position count, pitch, mounting type, and locking features. The difference in contact configuration (1-sided versus 2-sided) requires verification that the cable assembly is compatible with the substitute connector type.

Q: What is the significance of the contact configuration difference?

A: The 2-sided contact configuration on the main part accommodates cable assemblies with contacts on both sides of the FFC ribbon. The 1-sided configuration on the substitute accommodates cable assemblies with contacts on a single side. The appropriate substitute depends on the cable assembly design in use.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0905003012 and TE Connectivity 487925-9 are RoHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the MSL rating for both parts?

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

Q: Why is the main part classified as obsolete?

A: The Molex 0905003012 is no longer in active production. The TE Connectivity 487925-9 is the active equivalent, ensuring continued availability for new designs and ongoing system support.

Q: Are the electrical ratings equivalent?

A: The main part specifies 250V at 2.5A. The substitute part does not provide explicit voltage and current ratings in the available documentation. Electrical compatibility should be confirmed against the specific application requirements and cable assembly specifications.
