CWR06MH685KP Equivalent & Substitute Parts

Part Overview

The CWR06MH685KP is a 6.8 µF conformal coated tantalum capacitor rated for 35 V, manufactured by Vishay Sprague under the military-grade MIL-PRF-55365/4 specification. This component is designed for surface mount applications in the 2915 (7338 Metric) package format with an operating temperature range of -55°C to 125°C. The part is currently active in production with 866 units available in bulk packaging. Substitute parts are identified when packaging format, inventory logistics, or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The CWR06MC685KB/PR qualifies as a direct substitute for the CWR06MH685KP based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria: capacitance value (6.8 µF), tolerance (±10%), rated voltage (35 V), conformal coating type, ESR characteristic (1.3 Ohm), operating temperature range (-55°C to 125°C), package format (2915/7338 Metric), physical dimensions, and military series designation (MIL-PRF-55365/4, CWR06). The primary distinction between these parts is packaging format: the main part is supplied in bulk packaging, while the substitute is supplied in tape and reel (TR) format. Both parts maintain identical compliance status (RoHS non-compliant, REACH Affected, EAR99 ECCN classification) and moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both the CWR06MH685KP and CWR06MC685KB/PR are active production components from Vishay Sprague with identical electrical performance and mechanical compatibility. Selection between these parts should be based on packaging requirements and supply chain logistics. The CWR06MH685KP in bulk packaging is suitable for applications requiring manual component handling or smaller quantity procurement. The CWR06MC685KB/PR in tape and reel format is optimized for automated assembly processes and high-volume production environments. Both parts maintain equivalent compliance status under RoHS non-compliant and REACH Affected classifications with EAR99 export control designation. No electrical or thermal performance differences exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can CWR06MC685KB/PR be used as a direct replacement for CWR06MH685KP in circuit design?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including capacitance, voltage rating, ESR, temperature range, and package dimensions. The only difference is packaging format (bulk versus tape and reel).

Q: What is the significance of the packaging format difference between these parts?

A: Packaging format affects supply chain handling and assembly methodology. Bulk packaging is suitable for manual assembly or low-volume applications. Tape and reel packaging is designed for automated pick-and-place assembly systems used in high-volume manufacturing.

Q: Are there any compliance or certification differences between these substitute parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, EAR99 ECCN classification, and MSL 1 moisture sensitivity level.

Q: Do these parts have the same physical footprint on a PCB?

A: Yes. Both parts use the 2915 (7338 Metric) package with identical dimensions of 0.285" L x 0.150" W (7.24mm x 3.81mm) and maximum seated height of 0.125" (3.17mm).

Q: Is there any performance difference in ESR or operating temperature between these parts?

A: No. Both parts have identical ESR of 1.3 Ohm at 100kHz and identical operating temperature range of -55°C to 125°C.
