Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECJ-RVC1H330K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 33pF (exact match required)
• Voltage Rating: 50V (minimum acceptable)
• Tolerance: ±10% (electrical performance tolerance)
• Dielectric Type: Ceramic with C0G/NP0 temperature coefficient (stability requirement)
• Array Configuration: 4 isolated capacitors (functional requirement)
• Package: 1206 (3216 Metric) surface mount (PCB layout compatibility)
• Mounting Type: Surface mount (assembly process compatibility)

The substitute part CKCA43C0G1H330K100AA from TDK Corporation meets all these criteria, providing functional and mechanical equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ECJ-RVC1H330K and CKCA43C0G1H330K100AA are classified as obsolete products. Selection between these parts should be based on current inventory availability and procurement lead times.

The TDK CKCA43C0G1H330K100AA substitute provides electrical and mechanical equivalence with identical capacitance, voltage rating, tolerance, dielectric properties, and package specifications. The maximum seated height difference (0.037" vs 0.043") is within typical PCB assembly tolerances for 1206 packages and does not affect functional compatibility.

Both components carry identical export classification (EAR99) and tariff codes (HTSUS 8532.24.0020), supporting equivalent regulatory and compliance status.

Frequently Asked Questions (FAQ)

Q: Can CKCA43C0G1H330K100AA be used as a direct replacement for ECJ-RVC1H330K?

A: Yes. Both parts share identical electrical specifications (33pF, 50V, ±10%, C0G/NP0), array configuration (4 isolated capacitors), and package format (1206 surface mount). The components are mechanically and functionally equivalent.

Q: What is the significance of the height difference between these parts?

A: The ECJ-RVC1H330K has a maximum seated height of 0.037" (0.95mm), while the CKCA43C0G1H330K100AA measures 0.043" (1.10mm). This 0.006" (0.15mm) difference is within standard PCB assembly tolerances for 1206 packages and does not impact board-level compatibility or clearance requirements in typical applications.

Q: Are there any compliance or certification differences?

A: No. Both components share identical export classification (EAR99), tariff codes (HTSUS 8532.24.0020), and moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and compliance status are equivalent.

Q: What packaging formats are available for the substitute part?

A: The CKCA43C0G1H330K100AA is supplied in Cut Tape (CT) packaging, while the original ECJ-RVC1H330K packaging format is not specified in the provided data. Confirm packaging requirements with your procurement or assembly process specifications.

Q: Why is substitution necessary for these obsolete parts?

A: Both the ECJ-RVC1H330K and CKCA43C0G1H330K100AA are classified as obsolete. Substitution becomes necessary when original inventory is depleted or procurement lead times become prohibitive. The TDK equivalent ensures design continuity and maintains electrical performance specifications for legacy system support.
