Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC4700D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 470 Ohms (exact match required)
• Tolerance: ±0.5% (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)
• Number of terminations: 2 (exact match required)

Compliance & Quality Parameters:

• Automotive qualification: AEC-Q200 (required for automotive applications)
• Composition: Thick Film (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Substitute parts must match all parameters listed above. Manufacturer and product status may differ, provided all electrical, mechanical, and compliance specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM4700D is a direct electrical and mechanical equivalent to the RK73H1HTTC4700D. Both parts are manufactured by KOA Speer Electronics, Inc., belong to the RK73H series, and maintain identical specifications across all critical parameters: 470 Ohm resistance, ±0.5% tolerance, 0.05W power rating, 0201 package format, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range.

The primary distinction is product status: the RK73H1HTTC4700D is classified as "Not For New Designs," while the RK73H1HTTCM4700D is designated as "Active." This status change reflects the manufacturer's product lifecycle management and indicates that the substitute part represents the current production standard.

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility in automotive and industrial applications requiring moisture-resistant thick film resistors.

Selection of the RK73H1HTTCM4700D is appropriate for new designs, production transitions, and long-term supply chain continuity. Existing designs using the RK73H1HTTC4700D can transition to the substitute without circuit redesign or performance impact.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM4700D be used as a direct replacement for the RK73H1HTTC4700D?

A: Yes. Both parts are electrically and mechanically identical. All specifications including resistance, tolerance, power rating, package format, temperature range, and automotive qualification are identical. The substitute part is the current active product from the same manufacturer series.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The RK73H1HTTC4700D is marked "Not For New Designs," indicating it has been superseded. The RK73H1HTTCM4700D is the active equivalent. The letter "M" in the part number designates the current production variant. All electrical and mechanical specifications remain unchanged.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RK73H1HTTC4700D and RK73H1HTTCM4700D carry AEC-Q200 automotive qualification and are designed for automotive-grade applications. Both feature moisture-resistant thick film construction and operate across the -55°C to 155°C temperature range required for automotive environments.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts use the identical 0201 package format (0603 metric equivalent) with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). No PCB layout modifications are required.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance specifications are identical.

Q: Which part should be specified for new designs?

A: The RK73H1HTTCM4700D should be specified for new designs. This part carries "Active" product status and represents the current manufacturing standard from KOA Speer Electronics, Inc. The RK73H1HTTC4700D is explicitly marked "Not For New Designs."

Q: Is there a difference in packaging or availability?
