Molex 0520302829 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0520302829 is a 28-position FPC (Flat Flexible) connector with vertical, single-sided contacts designed for 1.00mm pitch applications. This connector features through-hole mounting, kinked pin termination, and zero insertion force (ZIF) operation. The part is classified as obsolete, making identification of active equivalent models necessary for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0520302829 is based on the following critical parameters that must remain constant:

• Number of positions: 28
• Pitch: 0.039" (1.00mm)
• Mounting type: Through hole
• Connector/contact type: Vertical - 1 sided
• Termination: Kinked pin
• Voltage rating: 50V
• Operating temperature range: -20°C ~ 80°C
• RoHS3 compliance
• FPC flat flex type

The substitute part Molex 0528062810 maintains these core electrical and mechanical parameters while transitioning from obsolete to active product status. Variations in secondary parameters such as housing material, locking feature, cable end type, and current rating are documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528062810 is the manufacturer-recommended substitute for the obsolete Molex 0520302829. Both parts maintain identical core specifications for position count, pitch, mounting configuration, and operating parameters. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part's housing material change from polyamide to polyphenylene sulfide (PPS) provides enhanced thermal and chemical resistance characteristics.

Design consideration: The substitute part specifies a current rating of 0.5A compared to the main part's 1A rating. Applications requiring the full 1A current capacity must evaluate this reduction against actual circuit requirements. The height above board increases from 5.20mm to 5.40mm, requiring verification of available PCB clearance in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528062810 directly replace the 0520302829 in existing designs?

A: The substitute part maintains identical position count, pitch, mounting type, and electrical ratings (50V, -20°C to 80°C operating range). PCB footprint compatibility is confirmed for through-hole mounting. However, the increased height above board (5.40mm vs. 5.20mm) and reduced current rating (0.5A vs. 1A) must be evaluated against specific design constraints.

Q: What are the differences in contact finish between these parts?

A: The main part uses tin bismuth contact finish, while the substitute uses tin finish. Both finishes provide equivalent electrical performance for the specified voltage and current applications within the stated operating temperature range.

Q: Does the cable end type difference affect compatibility?

A: The main part features tapered cable end type, while the substitute features straight cable end type. This affects the physical interface with the mating FPC cable but does not impact electrical compatibility. Cable selection must match the connector's cable end type specification.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Molex 0520302829 and 0528062810 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the housing material change?

A: The substitute part uses polyphenylene sulfide (PPS) housing instead of polyamide (PA66/Nylon 6/6). PPS provides superior thermal stability and chemical resistance, which may benefit applications exposed to elevated temperatures or harsh chemical environments within the specified operating range.
