Engineering Selection Recommendations

All three parts listed—VCAS120642L800DP, VC120642L800DP, and VCAS120642L800TP—are active products from KYOCERA AVX with identical electrical specifications and mechanical compatibility. Each component carries AEC-Q200 automotive qualification and ROHS3 compliance, satisfying the regulatory and quality requirements of automotive-grade applications.

The parts differ in packaging designation (DP and TP suffixes indicating different tape configurations in Tape & Reel packaging). Selection between these substitutes is based on inventory availability and tape reel packaging specifications relevant to your procurement and assembly processes.

VC120642L800DP represents a product line variant without explicit automotive grade designation in the provided data, while VCAS120642L800DP and VCAS120642L800TP both specify automotive grade status. When automotive compliance is a contractual requirement, selection should be limited to VCAS120642L800DP or VCAS120642L800TP.

Frequently Asked Questions (FAQ)

Q: Can VC120642L800DP be used in applications originally designed for VCAS120642L800DP? A: The electrical parameters and mechanical compatibility are identical between these parts. Selection depends on whether automotive grade certification is required by your application specification and procurement standards.

Q: What is the difference between the DP and TP packaging designations? A: Both designations indicate Tape & Reel (TR) packaging configurations. The DP and TP suffixes specify different tape reel specifications. Confirmation of tape specifications with your supplier is necessary for assembly equipment compatibility.

Q: Are all three parts pin-to-pin compatible? A: Yes. All three parts utilize the identical 1206 (3216 Metric) surface mount package and MLCV mounting type. No PCB layout modifications are required when substituting between these parts.

Q: Which part should be selected for new automotive designs? A: For new automotive designs requiring AEC-Q200 qualification, either VCAS120642L800DP or VCAS120642L800TP is appropriate. Verify the tape reel configuration (DP vs. TP) meets your assembly process requirements.

Q: What is the operating temperature range for all substitute parts? A: All three parts operate within the range of -55°C to 125°C (Ambient Temperature), suitable for automotive and industrial temperature environments.

Q: Are environmental compliance certifications identical across all three parts? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. MSL rating of 1 (Unlimited) applies to all three parts.
