Engineering Selection Recommendations

Primary Part Selection (CWR29KC155KCDB): The CWR29KC155KCDB maintains active production status with confirmed inventory availability of 606 pieces. This part is suitable for applications where RoHS non-compliance is acceptable within the design and regulatory framework.

Substitute Part Selection (293D155X9050D2TE3): The 293D155X9050D2TE3 from Vishay Sprague is functionally equivalent based on shared electrical specifications (1.5 µF capacitance, 50 V rating) and identical environmental classifications (MSL 1, ECCN EAR99, HTSUS 8532.21.0050). This substitute offers higher inventory availability (1442 pieces) and ROHS3 compliance, which may be advantageous for designs requiring regulatory alignment. The substitute is supplied in Tape & Reel packaging format, differing from the bulk packaging of the primary part.

Compliance Consideration: The primary part is RoHS non-compliant, while the substitute is ROHS3 compliant. Selection between these parts depends on the specific regulatory requirements of the end application and target markets.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution between CWR29KC155KCDB and 293D155X9050D2TE3?

A: Both parts share identical capacitance (1.5 µF) and voltage rating (50 V). These are the primary electrical parameters that establish functional equivalence. The substitute part specifies ±10% tolerance and 2.9 Ohm ESR, providing additional technical detail not available for the primary part.

Q: Are there packaging differences between these parts?

A: Yes. The CWR29KC155KCDB is supplied in Bulk packaging, while the 293D155X9050D2TE3 is supplied in Tape & Reel (TR) format. The substitute uses a 2917 (7343 Metric) package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.122" (3.10mm). Packaging format selection depends on assembly process requirements and handling procedures.

Q: What is the significance of the RoHS compliance difference?

A: The primary part (CWR29KC155KCDB) is RoHS non-compliant, while the substitute (293D155X9050D2TE3) is ROHS3 compliant. This difference is relevant for applications subject to RoHS directives or customer specifications requiring compliance. Design teams must verify regulatory requirements before selecting between these parts.

Q: Do both parts have identical moisture sensitivity requirements?

A: Yes. Both the CWR29KC155KCDB and 293D155X9050D2TE3 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. This parameter is identical across both parts.

Q: What export classifications apply to these parts?

A: Both parts share identical export classifications: ECCN EAR99 and HTSUS 8532.21.0050. These classifications are consistent across the primary and substitute parts.

Q: Which part should be selected based on inventory availability?

A: The substitute part 293D155X9050D2TE3 has higher inventory availability (1442 pieces) compared to the primary part (606 pieces). Inventory selection depends on project timeline and supply chain requirements.
