Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC5R10F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.1 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All substitute parts must maintain identical electrical and mechanical specifications across these parameters. Deviations in any parameter disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM5R10F is the direct equivalent substitute for RK73H1HTTC5R10F. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73H series, and maintain identical electrical and mechanical specifications.

The primary distinction is product status: RK73H1HTTC5R10F is designated "Not For New Designs," while RK73H1HTTCM5R10F carries "Active" status. For new design implementations and ongoing production requirements, RK73H1HTTCM5R10F is the appropriate selection. Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, ensuring regulatory and quality requirements are met in either case.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM5R10F be used as a direct replacement for RK73H1HTTC5R10F in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 5.1 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package, ±400ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 rating, and MSL 1 moisture sensitivity. Pin-for-pin and footprint compatibility is maintained.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC5R10F?

A: This designation indicates the part has been superseded in the manufacturer's active product line. While existing inventory remains available and the part continues to function within specification, KOA Speer Electronics recommends transitioning to active alternatives for new design work. RK73H1HTTCM5R10F is the active equivalent.

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

A: No. Both parts maintain identical compliance certifications: AEC-Q200 automotive qualification, ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Regulatory and quality requirements are equivalent.

Q: What packaging formats are available for these parts?

A: The main part RK73H1HTTC5R10F is supplied in Tape & Reel (TR) format. Packaging information for RK73H1HTTCM5R10F was not specified in the provided data.

Q: Are these parts suitable for automotive applications?

A: Yes. Both components meet AEC-Q200 qualification standards and are rated for automotive use across the -55°C to 155°C operating temperature range with moisture-resistant thick film construction.
