FI-X30S-HF-NPB Equivalent & Substitute Parts

Part Overview

The FI-X30S-HF-NPB is a 30-position rectangular receptacle connector manufactured by JAE Electronics, designed for surface mount, right-angle board-to-cable applications. This connector features gold-plated mating contacts, solder termination, and friction lock fastening. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FI-X30S-HF-NPB are identified based on the following critical parameters that determine functional equivalence:

• Number of Positions: 30 positions (exact match required)
• Pitch - Mating: 0.039" (1.00mm) (exact match required)
• Mounting Type: Surface Mount, Right Angle (exact match required)
• Termination: Solder (exact match required)
• Material Flammability Rating: UL94 V-0 (compliance requirement)

The substitute parts listed below meet these core criteria. However, differences exist in connector category (FFC/FPC vs. rectangular), contact material, and electrical ratings. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The FI-X30S-HF-NPB is obsolete; however, active alternatives exist. Selection between substitute parts must account for the following factors:

Electrical Derating: Both Molex alternatives (0527933070 and 0528523070) operate at reduced current (0.5A vs. 1A) and voltage (50V vs. 200V) ratings. Applications requiring the original 1A per contact or 200V rating cannot use these substitutes without circuit redesign.

Connector Type Transition: The original part is a rectangular receptacle connector; the substitutes are FFC/FPC connectors. This represents a category change that may require mechanical redesign of mating interfaces and cable assemblies.

Compliance Status: Both Molex substitutes carry active product status and ROHS3 compliance certification, providing supply chain continuity and regulatory alignment. The original JAE part carries no specified RoHS status.

Contact Interface Differences: The original uses gold-plated copper alloy contacts; substitutes use tin bismuth-plated phosphor bronze contacts. Contact finish and material differences may affect mating force, wear characteristics, and corrosion resistance in specific environments.

Mechanical Envelope: Substitute parts have greater height above board (0.122" vs. 0.061"), which may impact PCB layout and enclosure clearance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0527933070 or 0528523070 directly replace the FI-X30S-HF-NPB?

A: Direct replacement is not possible without design modification. While all three parts share 30 positions, 1.00mm pitch, surface mount right-angle mounting, and solder termination, the Molex parts are FFC/FPC connectors (flat flexible cable connectors) rather than rectangular connectors. The mating interface, cable assembly, and mechanical mounting differ fundamentally. Additionally, electrical ratings are reduced (0.5A vs. 1A; 50V vs. 200V).

Q: What are the key differences between 0527933070 and 0528523070?

A: Both are Molex Easy-On series FPC connectors with identical electrical and mechanical specifications. The primary difference is contact orientation: 0527933070 has contacts on top; 0528523070 has contacts on bottom. Selection depends on cable routing and PCB layout requirements.

Q: Are the Molex substitutes suitable for high-current or high-voltage applications?

A: No. The Molex alternatives are rated for 0.5A per contact and 50V maximum, compared to the original 1A per contact and 200V. Applications requiring these higher ratings cannot use these substitutes.

Q: What is the impact of the different contact finishes?

A: The original FI-X30S-HF-NPB uses gold plating (0.099µm thickness) on copper alloy contacts. The Molex substitutes use tin bismuth plating on phosphor bronze contacts. Gold provides superior corrosion resistance and lower contact resistance; tin bismuth is cost-effective but may show higher contact resistance over time in corrosive environments or after extended storage.

Q: Do the Molex parts meet the same flammability standards?

A: Yes. Both Molex substitutes carry UL94 V-0 certification, matching the original part's material flammability rating.

Q: What is the significance of the height difference (0.061" vs. 0.122")?

A: The Molex substitutes are approximately twice as tall above the PCB. This may create clearance conflicts with enclosures, adjacent components, or mechanical assemblies designed for the original connector's lower profile.

Q: Are the Molex parts RoHS compliant?

A: Yes. Both Molex substitutes are ROHS3 compliant. The original JAE part does not specify RoHS status.
