Key Parameters

Substitute Part Grouping Explanation

The substitute part 04021JR45ZBSTR\500 is classified as a parametric equivalent based on the following criteria:

Identical Electrical Parameters:

• Capacitance: 0.45 pF
• Tolerance: ±0.01 pF
• Voltage Rating: 100 V
• Operating Temperature Range: -55°C to 125°C

Identical Mechanical Parameters:

• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.039" L x 0.022" W (1.00 mm x 0.55 mm)
• Height - Seated (Max): 0.020" (0.50 mm)

Identical Compliance & Quality:

• Series: Accu-P®
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Packaging Difference: The only distinction between the main part and substitute is the packaging format: Tape & Reel (TR) versus Cut Tape (CT). This difference affects procurement and handling but does not impact electrical or mechanical performance in the final assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the 04021JR45ZBSTR and 04021JR45ZBSTR\500 are Active products with identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements rather than functional performance:

04021JR45ZBSTR (Tape & Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging provides optimal feeder compatibility and component handling efficiency.

04021JR45ZBSTR\500 (Cut Tape): Appropriate for lower-volume applications, prototype builds, or situations where smaller quantity procurement is required. Cut tape packaging accommodates manual or semi-automated placement processes.

Both parts maintain full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can 04021JR45ZBSTR\500 (Cut Tape) be used as a direct replacement for 04021JR45ZBSTR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Cut tape can be used in any application where tape & reel was specified, provided your assembly process accommodates cut tape handling.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place equipment. Cut Tape packaging provides components on a tape strip cut to specific lengths, typically used for lower volumes or manual assembly. Both formats contain the same component.

Q: Are there any electrical performance differences between these substitute parts?

A: No. Both parts have identical capacitance (0.45 pF), tolerance (±0.01 pF), voltage rating (100 V), temperature range (-55°C to 125°C), and RF characteristics (high Q, low loss).

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.022" W, 1.00 mm x 0.55 mm) and maximum seated height (0.020" / 0.50 mm).

Q: Are both parts RoHS compliant?

A: Yes. Both 04021JR45ZBSTR and 04021JR45ZBSTR\500 are ROHS3 compliant with REACH unaffected status.

Q: Which part should I choose for my design?

A: Selection depends on your procurement volume and assembly process. For high-volume automated assembly, use tape & reel. For prototype, low-volume, or manual assembly applications, cut tape is appropriate. Electrical and mechanical performance are identical.
