Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCS0402UD2002BE100 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 kOhms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W)
• Package format: 0402 (1005 Metric)
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• Environmental features: Anti-Sulfur, Moisture Resistant
• Compliance: ROHS3, REACH Unaffected

The substitute part MCS0402MD2002BE100 maintains identical electrical and mechanical specifications across all these parameters, differing only in internal manufacturing process designation (UD vs. MD suffix) and minor seated height variation (0.014" vs. 0.015" maximum).

Parameter Comparison

Engineering Selection Recommendations

Both MCS0402UD2002BE100 and MCS0402MD2002BE100 are active production components from Vishay Beyschlag/Draloric/BC Components with identical electrical performance and automotive qualification. Selection between these parts should be based on:

• Inventory availability: MCS0402MD2002BE100 offers significantly higher stock levels (5400 pcs vs. 857 pcs)
• PCB assembly clearance: The 0.001" (0.02mm) difference in maximum seated height is negligible for standard 0402 footprints but should be verified for high-density layouts with minimal clearance
• Supply chain continuity: Both parts maintain active status and ROHS3/REACH compliance

Frequently Asked Questions (FAQ)

Q: Can MCS0402MD2002BE100 be used as a direct replacement for MCS0402UD2002BE100?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, temperature coefficient, and operating range. The suffix designation (UD vs. MD) indicates internal manufacturing process variation only and does not affect functional performance.

Q: What is the significance of the seated height difference (0.014" vs. 0.015")?

A: The 0.001" (0.02mm) maximum seated height variation falls within standard 0402 package tolerances and does not impact PCB assembly for typical designs. High-density layouts with critical clearance requirements should reference the specific PCB footprint design rules.

Q: Are both parts suitable for automotive applications?

A: Yes. Both MCS0402UD2002BE100 and MCS0402MD2002BE100 carry AEC-Q200 automotive qualification, anti-sulfur coating, and moisture resistance, meeting automotive reliability standards.

Q: What compliance certifications apply to these parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Why would I choose one part over the other if they are equivalent?

A: Selection is primarily driven by inventory availability and supply chain requirements. MCS0402MD2002BE100 offers substantially higher stock levels, making it preferable for high-volume production or time-sensitive procurement scenarios.
