Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECJ-2VC1H090D are classified based on strict adherence to the following allowed parameters:

Direct Equivalents maintain identical electrical specifications: 9 pF capacitance, ±0.5pF tolerance, 50V voltage rating, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating range. These parts are interchangeable at the circuit level and PCB assembly level without design modification.

Upgrade Substitute (08051A9R0CAT2A) increases the voltage rating to 100V while maintaining 9 pF capacitance. The tolerance tightens to ±0.25pF. This part is suitable for applications requiring higher voltage margin or improved stability, though it introduces different physical thickness (0.037" vs. 0.028" maximum).

Parametric Equivalent (0805N9R0D500CT) matches all electrical parameters of the original part and maintains identical physical dimensions and thickness.

Substitution eligibility is determined exclusively by: capacitance value, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, and physical dimensions. All substitute parts listed maintain MSL 1 rating and are RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrically and Mechanically Identical):

• CC0805DRNPO9BN9R0 (YAGEO): Active product status with highest inventory availability (16950 Pcs). RoHS3 compliant, REACH unaffected. Thickness of 0.024" (0.60mm) is thinner than original, suitable for space-constrained applications.
• CL21C090DBANNNC (Samsung Electro-Mechanics): Active product status with substantial inventory (80200 Pcs). RoHS3 compliant, REACH unaffected. Thickness of 0.030" (0.75mm) closely matches original specification.
• 08055A9R0DAT2A (KYOCERA AVX): Active product status. RoHS3 compliant, REACH unaffected. Thickness of 0.037" (0.94mm) requires PCB layout verification for clearance.
• 08055A9R0DAT4A (KYOCERA AVX): Active product status. RoHS3 compliant, REACH unaffected. Identical specifications to 08055A9R0DAT2A.
• 0805N9R0D500CT (Walsin Technology Corporation): Active product status. RoHS3 compliant, REACH unaffected. Thickness of 0.028" (0.70mm) matches original closely.

Upgrade Substitute (Higher Voltage Rating):

• 08051A9R0CAT2A (KYOCERA AVX): 100V rating with tighter ±0.25pF tolerance. Active product status with high inventory (19197 Pcs). RoHS3 compliant, REACH unaffected. Increased thickness of 0.037" (0.94mm) requires PCB layout verification. Suitable for designs requiring enhanced voltage margin or improved temperature stability.

All substitute parts maintain MSL 1 rating and operate across -55°C ~ 125°C temperature range. Selection should prioritize active product status and inventory availability for supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can I use 08051A9R0CAT2A as a direct replacement for ECJ-2VC1H090D? A: 08051A9R0CAT2A is an upgrade substitute with 100V rating versus the original 50V. It maintains 9 pF capacitance and C0G/NP0 temperature coefficient. The tighter tolerance (±0.25pF) and increased thickness (0.037" vs. 0.028") require verification that your circuit design and PCB layout accommodate these changes. Use only if your application benefits from higher voltage rating.

Q: What is the difference between the KYOCERA AVX parts 08055A9R0DAT2A and 08055A9R0DAT4A? A: Both parts are electrically and mechanically identical: 9 pF, ±0.5pF, 50V, C0G/NP0, 0805 package, 0.037" maximum thickness. The difference lies in packaging designation (DAT2A vs. DAT4A), which may reflect different tape reel configurations or manufacturing batches. Consult the manufacturer for specific packaging details if your assembly equipment has tape compatibility requirements.

Q: Why does CC0805DRNPO9BN9R0 have a different thickness than the original part? A: CC0805DRNPO9BN9R0 has a maximum thickness of 0.024" (0.60mm) compared to the original 0.028" (0.70mm). This thinner profile is within the 0805 package specification and does not affect electrical performance. Verify that your PCB assembly process and component placement equipment accommodate this variation.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All active substitute parts listed (CC0805DRNPO9BN9R0, CL21C090DBANNNC, 08055A9R0DAT2A, 08055A9R0DAT4A, 08051A9R0CAT2A, and 0805N9R0D500CT) are RoHS3 compliant and REACH unaffected.

Q: Which substitute has the best inventory availability? A: CL21C090DBANNNC (Samsung Electro-Mechanics) has the highest inventory at 80200 Pcs. CC0805DRNPO9BN9R0 (YAGEO) is the second option with 16950 Pcs available.

Q: Can I mix different substitute parts in the same production batch? A: All direct equivalent substitutes maintain identical electrical specifications (9 pF, ±0.5pF, 50V, C0G/NP0). Physical thickness variations (0.024" to 0.037") may require separate PCB assembly runs if your equipment has strict height tolerance settings. Consult your assembly partner regarding component height uniformity requirements.
