RK73H1HTTC2200D Equivalent & Substitute Parts

Part Overview

The RK73H1HTTC2200D is a 220 Ohm ±0.5% thick film chip resistor rated at 0.05W (1/20W) in 0201 package format (0.60mm x 0.30mm metric). This component is manufactured by KOA Speer Electronics, Inc. and meets automotive AEC-Q200 qualification standards with moisture-resistant construction.

The RK73H1HTTC2200D carries a product status of "Not For New Designs," indicating it has been superseded in the manufacturer's active product line. Identification of equivalent substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this resistor specification remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2200D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 220 Ohms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity level: MSL 1

All substitute parts must maintain identical electrical performance and physical dimensions. The 0201 package constraint is absolute; no larger or smaller packages qualify as direct substitutes. The AEC-Q200 automotive qualification requirement must be preserved for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM2200D is the direct equivalent substitute for the RK73H1HTTC2200D. Both components are manufactured by KOA Speer Electronics, Inc. and share identical electrical specifications, physical dimensions, and automotive qualification status.

The primary distinction is product lifecycle status: the original RK73H1HTTC2200D is designated "Not For New Designs," while the RK73H1HTTCM2200D maintains "Active" status in the manufacturer's current product portfolio. This substitution is appropriate for applications requiring ongoing component availability and manufacturing continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for automotive and industrial applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM2200D be used as a direct replacement for RK73H1HTTC2200D in existing designs?

A: Yes. The RK73H1HTTCM2200D is electrically and mechanically identical to the RK73H1HTTC2200D across all specified parameters. Both components deliver 220 Ohms ±0.5% resistance at 0.05W power rating in 0201 package format with identical temperature performance and automotive qualification.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the RK73H1HTTC2200D has been superseded in the manufacturer's active product line. The RK73H1HTTCM2200D represents the current production equivalent. For new designs and ongoing production, the active substitute part is the recommended selection.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 0201 package format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RK73H1HTTC2200D and RK73H1HTTCM2200D carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification level.

Q: What is the difference between the part numbers?

A: The part numbers differ only in the suffix: RK73H1HTTC2200D versus RK73H1HTTCM2200D. This variation reflects the manufacturer's internal product line management and does not indicate functional differences. Both parts share the base product number RK73H1H and belong to the RK73H series.
