ECQ-E2104JFZ Equivalent & Substitute Parts

Part Overview

The ECQ-E2104JFZ is a 0.1 µF film capacitor rated for 250V DC operation with polyester metallized dielectric construction. This radial through-hole component is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when inventory constraints or supply chain requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E2104JFZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±5% (exact match required)
• DC voltage rating: 250V minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (equal or wider range acceptable)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Termination style: PC Pins (exact match required)

The ECQ-E2104JF qualifies as a parametric equivalent under these criteria, maintaining identical capacitance, tolerance, dielectric composition, physical dimensions, and termination specifications. The AC voltage rating addition in the substitute part does not affect DC-only applications and represents an enhancement to the electrical specification envelope.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-E2104JFZ and ECQ-E2104JF maintain Active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences. The ECQ-E2104JF provides equivalent functionality with identical DC voltage rating, capacitance, tolerance, and physical form factor. Both parts are suitable for direct substitution in through-hole PCB applications requiring 0.1 µF capacitance at 250V DC with polyester film dielectric construction.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2104JF replace ECQ-E2104JFZ in my circuit?

A: Yes. The ECQ-E2104JF is a parametric equivalent with identical capacitance (0.1 µF), tolerance (±5%), DC voltage rating (250V), dielectric material (polyester metallized), physical dimensions, lead spacing (7.50mm), and termination style (PC pins). Both parts are rated for -40°C to 105°C operation and are ROHS3 compliant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions of 0.406" L x 0.228" W (10.30mm x 5.80mm) with maximum seated height of 0.370" (9.40mm) and lead spacing of 0.295" (7.50mm). Direct PCB footprint compatibility is confirmed.

Q: What is the difference between ECQ-E2104JFZ and ECQ-E2104JF?

A: The ECQ-E2104JF includes an AC voltage rating specification of 150V, which the ECQ-E2104JFZ does not specify. For DC-only applications, this difference does not affect performance. Both parts maintain identical DC ratings and all other electrical and mechanical specifications.

Q: Are both parts suitable for industrial temperature ranges?

A: Yes. Both ECQ-E2104JFZ and ECQ-E2104JF operate across the identical temperature range of -40°C to 105°C, meeting industrial application requirements.

Q: Do these parts require any special handling or storage considerations?

A: Both parts are ROHS3 compliant with moisture sensitivity level not applicable. Standard through-hole component handling and storage practices apply.
