Parameter Comparison

Engineering Selection Recommendations

Both the 04023J1R2ABWTR and 04023J1R2ABSTR are active production components with identical electrical and mechanical specifications. The primary distinction lies in regulatory compliance status. The substitute part 04023J1R2ABSTR is ROHS3 compliant and REACH unaffected, whereas the main part is RoHS non-compliant and REACH affected. Selection between these parts should be based on regulatory requirements applicable to the end application and target market. The substitute part offers superior compliance posture for applications subject to RoHS3 and REACH regulations. Both parts maintain equivalent performance characteristics for RF and high-frequency circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 04023J1R2ABSTR be used as a direct replacement for 04023J1R2ABWTR?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (1.2 pF), tolerance (±0.05 pF), voltage rating (25 V), package (0402), and operating temperature range (-55°C to 125°C). Direct substitution is supported without circuit redesign.

Q: What is the difference between these two part numbers?

A: The primary differences are regulatory compliance and inventory availability. The 04023J1R2ABSTR is ROHS3 compliant and REACH unaffected, while 04023J1R2ABWTR is RoHS non-compliant and REACH affected. The substitute part has higher stock availability (9508 units versus 873 units).

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.039" L x 0.022" W (1.00 mm x 0.55 mm) with a maximum seated height of 0.020" (0.50 mm). PCB footprints and assembly processes remain unchanged.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 or REACH regulations, 04023J1R2ABSTR is the appropriate selection. For applications without regulatory constraints, either part is functionally equivalent.

Q: Is the packaging format the same?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format, maintaining identical handling and assembly compatibility.
