Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN385B-2 is determined by the following critical parameters:

• Connector Style & Type: Both parts must conform to IEC 320-C14 standard with receptacle, male blades configuration
• Position Count: Maintained at 3 positions for electrical continuity
• Filter Characteristics: EMI/RFI filtering capability required; current rating must support application requirements
• Mounting Configuration: Panel mount, snap-in installation method
• Fuse Accommodation: Fuse holder capability must be present
• Panel Compatibility: Panel thickness range must overlap with installation environment
• Regulatory Compliance: RoHS3 compliance required; additional certifications (CSA, UL, VDE) enhance compatibility

The substitute part 1609988-2 shares the core IEC 320-C14 receptacle architecture and panel mount snap-in design. However, differences in current rating, termination method, and panel cutout specifications require engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

FN385B-2 (Schaffner EMC Inc.): Suitable for legacy system maintenance and production support where existing designs require component replacement. The "Not For New Designs" status indicates this part is in end-of-life phase. Continued availability is limited to existing inventory (844 pcs). Regulatory approvals include CSA, UL, and VDE certifications, supporting medical and commercial applications.

1609988-2 (TE Connectivity Raychem Cable Protection): Represents an active product with ongoing manufacturing support. This part is appropriate for new designs or redesigns requiring IEC 320-C14 receptacle functionality. The lower current rating (3A vs. 10A) and reduced panel thickness accommodation range (0.032" ~ 0.080" vs. 0.031" ~ 0.126") require verification against specific application requirements. Termination method differs (Quick Connect vs. Solder Eyelet), necessitating PCB or harness redesign. REACH compliance status differs between parts.

Selection between these parts depends on application current requirements, panel thickness specifications, and termination infrastructure compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1609988-2 directly replace FN385B-2 in existing assemblies?

A: Direct replacement requires verification of three factors: (1) application current demand must not exceed 3A (1609988-2 rating), (2) panel thickness must fall within 0.032" ~ 0.080" range, and (3) termination method compatibility—1609988-2 uses Quick Connect terminals while FN385B-2 uses Solder Eyelet, requiring different PCB or harness configurations.

Q: What are the key differences affecting substitution?

A: Current rating differs significantly (10A vs. 3A). Panel thickness accommodation is narrower for 1609988-2. Termination methods are incompatible without redesign. Filter type classification differs (Commercial/Medical vs. Commercial only). These differences determine substitution feasibility on an application-specific basis.

Q: Are both parts RoHS3 compliant?

A: Yes, both FN385B-2 and 1609988-2 carry ROHS3 Compliant status. However, REACH compliance status differs—FN385B-2 is REACH Unaffected while 1609988-2 is REACH Affected, which may impact supply chain documentation requirements.

Q: Which part should be selected for new designs?

A: 1609988-2 is the appropriate choice for new designs, as it maintains active product status with ongoing manufacturer support. FN385B-2 is designated "Not For New Designs" and represents end-of-life inventory.

Q: What is the significance of the panel cutout dimension difference?

A: FN385B-2 specifies variable panel cutout dimensions, while 1609988-2 defines a fixed rectangular cutout (29.00mm x 33.00mm). This affects panel preparation and mechanical fit. Variable vs. fixed specifications require verification against specific panel designs.
