Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC30R9D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30.9 Ohms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must satisfy all mandatory parameters without deviation. The RK73H1HTTCM30R9D meets these criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM30R9D is the manufacturer-recommended substitute for the RK73H1HTTC30R9D. Both components are manufactured by KOA Speer Electronics, Inc., and belong to the RK73H series.

Key Distinction: The RK73H1HTTCM30R9D carries an "Active" product status, whereas the main part is designated "Not For New Designs." This status difference reflects manufacturing lifecycle positioning rather than functional or electrical divergence.

Compliance and Certification: Both parts maintain identical compliance profiles:

• AEC-Q200 automotive qualification
• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification
• Moisture sensitivity level 1 (unlimited shelf life)

Electrical and Mechanical Equivalence: All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) and mechanical specifications (package dimensions, termination count, height) are identical between the main part and substitute.

The RK73H1HTTCM30R9D is suitable for direct replacement in applications currently using the RK73H1HTTC30R9D, with no circuit redesign or validation required.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM30R9D replace the RK73H1HTTC30R9D in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The RK73H1HTTCM30R9D is the manufacturer-recommended substitute and carries active product status, making it the preferred choice for ongoing production and support.

Q: What does "Not For New Designs" mean for the RK73H1HTTC30R9D?

A: This designation indicates the part has reached end-of-life in the manufacturer's product roadmap. While existing inventory remains available, KOA Speer Electronics recommends transitioning to the RK73H1HTTCM30R9D for new applications and future production runs.

Q: Are the package dimensions identical between these parts?

A: Yes. Both components use the 0201 package (0603 metric) with identical dimensions: 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: Do both parts meet automotive qualification requirements?

A: Yes. Both the RK73H1HTTC30R9D and RK73H1HTTCM30R9D carry AEC-Q200 qualification and are suitable for automotive applications across the -55°C to 155°C operating temperature range.

Q: What is the difference in moisture sensitivity between these parts?

A: There is no difference. Both parts have moisture sensitivity level 1, indicating unlimited shelf life without special storage requirements.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory and compliance profiles are identical.
