Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808GC151MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Capacitance: 150 pF
• Voltage - Rated: 2000V (2kV)
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount, MLCC
• Package / Case: 1808 (4520 Metric)

Allowed Variance:

• Tolerance: ±20% or tighter (±10% is acceptable)
• Physical dimensions: Minor variations within standard manufacturing tolerances for the 1808 package are permissible
• Thickness: Variations within the 1808 package specification are acceptable

The substitute part VPDP202W151K1GV001E by Johanson Dielectrics Inc. meets all substitution criteria with matching capacitance, voltage rating, temperature coefficient, and package designation. The tighter tolerance (±10% versus ±20%) represents an improvement in specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808GC151MAT1A and VPDP202W151K1GV001E are active production components with full regulatory compliance. Selection between these parts should be based on:

Inventory Availability: The 1808GC151MAT1A has 755 units in stock, while VPDP202W151K1GV001E has 7491 units available.

Tolerance Requirements: Applications requiring tighter capacitance tolerance specifications benefit from the VPDP202W151K1GV001E (±10% tolerance versus ±20%).

Packaging Format: The 1808GC151MAT1A is supplied in standard packaging, while VPDP202W151K1GV001E is supplied in Tape & Reel (TR) format, which is suitable for automated assembly processes.

Compliance Status: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can VPDP202W151K1GV001E be used as a direct replacement for 1808GC151MAT1A?

A: Yes. Both parts share identical electrical specifications (150 pF, 2000V, X7R, -55°C ~ 125°C) and are packaged in the 1808 (4520 Metric) form factor. Physical dimensions fall within acceptable manufacturing tolerances for the 1808 package classification.

Q: What is the significance of the tolerance difference (±20% versus ±10%)?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal 150 pF value. The ±10% tolerance of VPDP202W151K1GV001E provides a narrower range (135–165 pF) compared to the ±20% range (120–180 pF) of 1808GC151MAT1A. Applications with strict capacitance requirements benefit from the tighter tolerance.

Q: Are there any physical installation considerations between these parts?

A: Both parts use surface-mount technology with the same package designation. The VPDP202W151K1GV001E has slightly larger dimensions (0.185" L x 0.080" W versus 0.181" L x 0.079" W) and greater thickness (0.085" versus 0.071"), but these variations remain within standard 1808 package specifications and do not affect PCB layout compatibility.

Q: What packaging formats are available?

A: The 1808GC151MAT1A is supplied in standard packaging. The VPDP202W151K1GV001E is supplied in Tape & Reel (TR) format, which is optimized for high-volume automated assembly operations.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard industrial and commercial manufacturing requirements.
