Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC470G is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 47 Ohms (exact match required)
• Tolerance: ±2% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package format: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height seated maximum: 0.010" (0.26mm) (exact match required)

Compliance & Quality Parameters:

• Automotive qualification: AEC-Q200 (exact match required)
• Composition: Thick Film (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match required)

Substitute parts must match all parameters listed above. Variations in manufacturer, series designation, or product status do not affect substitution eligibility provided all electrical, mechanical, and compliance specifications are identical.

For existing designs currently using RK73B1HTTC470G, RK73B1HTTCM470G provides direct substitution without circuit redesign, layout modification, or performance impact. Both parts maintain identical compliance certifications including AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating.

Inventory availability is sufficient for both parts, with 1068 units of the original part and 1018 units of the substitute currently in stock.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM470G be used as a direct replacement for RK73B1HTTC470G in existing assemblies?

A: Yes. RK73B1HTTCM470G is electrically and mechanically identical to RK73B1HTTC470G. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range), mechanical dimensions (0201 package, 0.60mm x 0.30mm), and compliance certifications (AEC-Q200, ROHS3, MSL 1) are identical. No circuit modifications, PCB layout changes, or performance adjustments are required.

Q: Why is RK73B1HTTC470G marked "Not For New Designs"?

A: "Not For New Designs" indicates the part has been superseded in the manufacturer's active product portfolio. RK73B1HTTCM470G is the active equivalent. For new design work, RK73B1HTTCM470G should be specified to ensure long-term supply chain continuity and manufacturer support.

Q: Are there any differences in packaging or handling between these two parts?

A: Both parts are supplied in 0201 package format with identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). Both carry MSL 1 (Unlimited) moisture sensitivity rating, requiring identical storage and handling procedures. Packaging format information for RK73B1HTTCM470G was not specified in available data; confirm packaging requirements with the supplier if tape & reel format is mandatory.

Q: Do these parts meet automotive qualification requirements?

A: Yes. Both RK73B1HTTC470G and RK73B1HTTCM470G are qualified to AEC-Q200 automotive standards. They are suitable for automotive applications requiring this certification level.

Q: What is the temperature coefficient specification, and does it differ between parts?

A: Both parts specify ±200ppm/°C temperature coefficient with an operating temperature range of -55°C to 155°C. This specification is identical for both the main part and substitute.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications. Regulatory and compliance status is identical.
