Substitute Part Grouping Explanation

Substitution for the TCE0806S-500-2P is determined by strict equivalence across the following critical parameters:

• Filter Type & Line Configuration: Signal line, 2-line common mode choke
• Impedance Specification: 50 Ohms @ 100 MHz
• Current Rating: 100mA maximum
• Mounting & Package: Surface mount, 0302 (0806 Metric) 6-lead package
• Protection Feature: TVS Diode ESD Protection
• Environmental Compliance: RoHS3 compliance and MSL rating

Two substitute parts meet these criteria with documented equivalence:

1. TCE0806S-500-2P-T200 (TDK Corporation) — Parametric equivalent with identical electrical specifications and packaging, differentiated only by cut tape packaging format.

2. LCFE080602W500TG (Littelfuse Inc.) — Manufacturer-recommended substitute with equivalent core functionality. This part maintains the same impedance, current rating, line configuration, and package footprint. Variations in DC resistance (7 Ohm vs. 2.5 Ohm) and voltage rating (5V vs. 10V) are within acceptable tolerance for signal line filtering applications.

Parameter Comparison

Engineering Selection Recommendations

TCE0806S-500-2P-T200 is the direct parametric equivalent. This TDK part maintains identical electrical specifications and physical dimensions. Selection of this substitute is appropriate when procurement from existing TDK supply chains is available and packaging format (cut tape) is compatible with assembly processes.

LCFE080602W500TG is the manufacturer-recommended active substitute. As an active product from Littelfuse Inc., this part provides long-term availability and supply continuity. The component meets all core functional requirements: 2-line configuration, 50 ohms impedance at 100 MHz, 100mA current rating, and integrated TVS diode ESD protection. Physical dimensions are within acceptable tolerance for 0806 metric footprint compatibility. The higher DC resistance (7 Ohm) and lower DC voltage rating (5V) are secondary parameters that do not affect signal line filtering performance in standard applications. ROHS3 compliance and MSL 1 rating match the original specification.

Selection between these substitutes depends on supply availability, packaging requirements, and long-term product lifecycle considerations. The Littelfuse part offers superior availability as an active product.

Frequently Asked Questions (FAQ)

Q: Can TCE0806S-500-2P-T200 be used as a direct replacement for TCE0806S-500-2P?

A: Yes. TCE0806S-500-2P-T200 is a parametric equivalent with identical electrical specifications, impedance, current rating, DC resistance, voltage rating, and physical dimensions. The only difference is packaging format (cut tape vs. original packaging). Both are obsolete TDK products.

Q: What are the key differences between LCFE080602W500TG and the original TCE0806S-500-2P?

A: The LCFE080602W500TG maintains equivalent impedance (50 Ohms @ 100 MHz), current rating (100mA), line configuration (2-line), and package footprint (0806 metric). Differences include: DC resistance of 7 Ohm (vs. 2.5 Ohm), DC voltage rating of 5V (vs. 10V), and extended operating temperature range (-40°C to 85°C vs. -25°C to 85°C). The LCFE part is an active product, ensuring long-term availability.

Q: Are the physical dimensions of LCFE080602W500TG compatible with TCE0806S-500-2P PCB layouts?

A: The LCFE080602W500TG dimensions are 0.034" L x 0.026" W x 0.022" H (0.87mm x 0.67mm x 0.55mm), compared to 0.033" L x 0.026" W x 0.018" H (0.85mm x 0.65mm x 0.45mm) for the original. These dimensions are within standard 0806 metric package tolerance and are compatible with existing PCB footprints designed for 0302 (0806 metric) components.

Q: Does LCFE080602W500TG meet the same compliance standards as TCE0806S-500-2P?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. LCFE080602W500TG is an active product with current compliance documentation, while TCE0806S-500-2P is obsolete. For new designs, LCFE080602W500TG provides verified compliance assurance.

Q: What is the impact of the higher DC resistance in LCFE080602W500TG?

A: The LCFE part has 7 Ohm DCR compared to 2.5 Ohm in the original. For signal line filtering at 100 MHz, this parameter affects insertion loss and heat dissipation at maximum current (100mA). At 100mA, the LCFE part dissipates approximately 70mW vs. 25mW for the original. This difference is acceptable in standard signal line applications but should be evaluated in power-sensitive designs.

Q: Can these parts be used interchangeably in production?

A: TCE0806S-500-2P and TCE0806S-500-2P-T200 are fully interchangeable. LCFE080602W500TG is functionally equivalent but requires validation for specific circuit performance due to DCR and voltage rating differences. Both substitutes are suitable for new production runs where the original part is unavailable.
