ECJ-0EB1H102K Equivalent & Substitute Parts

Part Overview

The ECJ-0EB1H102K is a 1000 pF ±10% 50V ceramic capacitor in X7R temperature coefficient, 0402 (1005 Metric) surface mount package manufactured by Panasonic Electronic Components. This part is classified as Obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering active product status from alternative manufacturers.

Key Parameters

Parameter	Value
Capacitance	1000 pF
Tolerance	±10%

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance: 1000 pF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 50V (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Package / Case: 0402 (1005 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed meet these criteria. Variations in physical dimensions (length, width, thickness) within standard tolerances, packaging format (Tape & Reel vs. Cut Tape), and regulatory compliance status do not affect electrical or mechanical substitutability.

Engineering Selection Recommendations

For new designs and ongoing production, select from parts with Active product status and ROHS3 compliance:

04025C102KAQ2A (KYOCERA AVX): Active status, ROHS3 compliant, REACH unaffected, 822 pcs available
04025C102KAT2A-62 (KYOCERA AVX): Active status, ROHS3 compliant, REACH unaffected, highest inventory at 15768 pcs, Tape & Reel packaging
TDCF500W102K1GV001T (Johanson Dielectrics Inc.): Active status, ROHS3 compliant, REACH unaffected, highest inventory at 85469 pcs
VJ0402Y102KXACW1BC (Vishay Vitramon): Active status, ROHS3 compliant, REACH unaffected, 15930 pcs available

For legacy system maintenance where Active status is not required, parts with Not For New Designs status remain electrically and mechanically equivalent. Parts with RoHS non-compliant status (04025C102KAJ2A, LD025C102KAB2A) are suitable only for applications without regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute ECJ-0EB1H102K with any of the listed parts?

A: Yes. All listed parts are electrically and mechanically equivalent. They share identical capacitance (1000 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and package (0402 / 1005 Metric). Selection should be based on product status, regulatory compliance requirements, and inventory availability.

Q: What is the difference between Active and Not For New Designs status?

A: Active status indicates the manufacturer continues production and supports the part for new designs. Not For New Designs status indicates the manufacturer no longer recommends the part for new applications but may continue limited production for legacy support. Both statuses provide equivalent electrical and mechanical performance.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a regulatory requirement related to hazardous substance content and does not affect electrical specifications or performance. Selection depends on application regulatory requirements.

Q: Are there packaging differences between substitute parts?

A: Packaging format varies (Tape & Reel vs. Cut Tape) but does not affect electrical or mechanical compatibility. Select based on assembly process requirements. Physical dimensions show minor variations within standard tolerances and do not affect board-level compatibility.

Q: Which substitute part has the best inventory availability?

A: TDCF500W102K1GV001T (Johanson Dielectrics Inc.) has the highest inventory at 85469 pcs. 04025C102KAT2A-62 (KYOCERA AVX) is the second highest at 15768 pcs.
