Substitute Part Grouping Explanation

Substitution of the TE Connectivity 6-1622821-9 is determined by strict equivalence across the following electrical and mechanical parameters:

Core Substitution Criteria:

• Resistance value: 220 mOhms (exact match required)
• Power rating: 0.25W minimum
• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Application feature: Current Sense capability
• Number of terminations: 2

Acceptable Parameter Variations:

• Tolerance: May be tighter (lower value) than ±5%
• Temperature coefficient: May be lower (improved stability)
• Operating temperature range: Must encompass or exceed -55°C to 125°C
• Product status: Active parts are preferred over obsolete

The two identified substitute parts meet all core substitution criteria while offering improved tolerance specifications and extended operating temperature ranges. Both substitute parts maintain identical package dimensions and current sense functionality.

Parameter Comparison

Engineering Selection Recommendations

Stackpole Electronics CSR0805FKR220: This part provides direct functional equivalence with improved tolerance specification (±1% versus ±5%) and lower temperature coefficient (±200ppm/°C). The extended operating temperature range to 155°C accommodates higher thermal environments. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance supports regulatory requirements for new designs.

Vishay Dale RCWE0805R220FKEA: This part offers the most stringent performance characteristics with ±1% tolerance and ±100ppm/°C temperature coefficient, providing superior stability in current sense applications. Automotive AEC-Q200 qualification and moisture-resistant construction extend reliability in demanding environments. Extended operating temperature range to 155°C and ROHS3 compliance support both automotive and industrial applications. Active product status with substantial inventory availability (5275 pcs) ensures supply security.

Both substitute parts are electrically and mechanically compatible with the obsolete TE Connectivity 6-1622821-9 and support direct board-level replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the Stackpole CSR0805FKR220 directly replace the TE Connectivity 6-1622821-9?

A: Yes. Both parts share identical resistance value (220 mOhms), power rating (0.25W), package type (0805), and current sense functionality. The Stackpole part features improved tolerance (±1% versus ±5%) and lower temperature coefficient (±200ppm/°C versus ±350ppm/°C), making it a direct functional upgrade.

Q: What is the primary advantage of the Vishay Dale RCWE0805R220FKEA over the Stackpole alternative?

A: The Vishay Dale part provides the lowest temperature coefficient (±100ppm/°C) among available substitutes, delivering superior resistance stability across temperature variations. Automotive AEC-Q200 qualification and moisture-resistant construction provide additional reliability for demanding applications. Both parts are electrically equivalent for standard current sense circuits.

Q: Are there physical dimension differences between these parts?

A: All three parts conform to the 0805 (2012 Metric) package standard with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height varies slightly: TE Connectivity at 0.020" (0.50mm), Stackpole at 0.026" (0.65mm), and Vishay Dale at 0.026" (0.65mm). These variations remain within standard PCB assembly tolerances and do not affect board-level compatibility.

Q: Do all substitute parts meet environmental and regulatory requirements?

A: Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original part. Moisture Sensitivity Level 1 (Unlimited) is maintained across all three parts, supporting standard handling and storage procedures.

Q: Which substitute part should be selected for new production designs?

A: Selection depends on application requirements. For standard current sense applications, the Stackpole CSR0805FKR220 provides cost-effective equivalence with improved tolerance. For automotive, high-reliability, or thermally demanding applications, the Vishay Dale RCWE0805R220FKEA offers superior performance characteristics through lower temperature coefficient and AEC-Q200 qualification.

Q: Are these parts cross-compatible in existing bill of materials?

A: Yes. All three parts are electrically and mechanically compatible for direct substitution in current sense circuits. PCB layouts and circuit designs require no modification. Component procurement can transition directly from the obsolete TE Connectivity part to either active substitute without design revision.
