Molex 0905003013 FFC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0905003013 is a 13-position flat flexible connector (FFC) with vertical contacts designed for through-hole PCB mounting at 0.100" (2.54mm) pitch. This connector features zero insertion force (ZIF) operation with a slide lock mechanism and is rated for 250V and 2.5A per contact. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Position Count: Must match exactly at 13 positions
• Pitch: Must match exactly at 0.100" (2.54mm)
• Mounting Type: Must be through-hole PCB mounting
• Voltage Rating: Substitute must meet or exceed 250V
• Current Rating: Substitute must meet or exceed 2.5A per contact
• Operating Temperature Range: Substitute must cover or exceed -40°C ~ 85°C
• Flammability Compliance: Must maintain UL94 V-0 rating
• RoHS Compliance: Must be RoHS compliant

The TE Connectivity AMP Connectors part number 6-520315-3 qualifies as a substitute based on matching position count, pitch, mounting type, voltage rating, flammability rating, and RoHS compliance. However, differences exist in contact configuration, current rating, temperature range, and mating cycle specifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-520315-3 is an active product with current manufacturing support, making it suitable for applications where the Molex 0905003013 obsolete status creates supply chain constraints. Both connectors maintain UL94 V-0 flammability compliance and RoHS regulatory compliance.

Selection between these connectors must account for the following differences:

The TE Connectivity substitute has a reduced current rating of 1A compared to the original 2.5A specification. Applications requiring the full 2.5A per-contact capacity must not use this substitute without circuit redesign or load redistribution analysis.

The TE Connectivity substitute features a single-sided contact configuration versus the original two-sided design. PCB layout compatibility must be verified to ensure proper mating with existing cable assemblies.

The TE Connectivity substitute provides an extended operating temperature range (-55°C ~ 105°C) that exceeds the original specification, offering broader environmental capability for extreme temperature applications.

The TE Connectivity substitute has a lower profile (6.93mm versus 8.80mm), which may provide space advantages in constrained PCB layouts but requires mechanical clearance verification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-520315-3 directly replace the Molex 0905003013 in all applications?

A: Direct replacement is possible only when application current requirements do not exceed 1A per contact and the single-sided contact configuration is compatible with existing cable assemblies. The reduced current rating and different contact geometry require application-specific validation.

Q: What is the primary difference between the two-sided and one-sided contact configurations?

A: The Molex original features contacts on both sides of the connector body, while the TE Connectivity substitute has contacts on one side only. This affects mating interface compatibility and PCB layout requirements. Existing cable assemblies designed for the two-sided configuration may not mate properly with the one-sided substitute.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0905003013 is ROHS3 compliant, and the TE Connectivity 6-520315-3 is RoHS compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: Does the TE Connectivity substitute support the same voltage rating?

A: Yes. Both connectors are rated for 250V operation, making them electrically equivalent for voltage specifications.

Q: Why is the current rating different between the two connectors?

A: The TE Connectivity substitute is designed for lower current applications (1A per contact) compared to the Molex original (2.5A per contact). This is a fundamental design difference that limits the substitute to lower-power circuit configurations.

Q: What is the significance of the mating cycle difference?

A: The Molex original supports 50 mating cycles, while the TE Connectivity substitute supports 25 cycles. For applications requiring frequent connector mating and unmatting, the original specification provides greater mechanical durability. The substitute is suitable for applications with infrequent connection changes.

Q: Can I use the TE Connectivity substitute in high-temperature environments?

A: The TE Connectivity substitute operates from -55°C to 105°C, which exceeds the original -40°C to 85°C range. It is suitable for extended temperature applications within its specified limits.
