Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1003D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 100 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The substitute part RK73G1HTTCM1003D meets all mandatory parameters and is manufactured by the same supplier (KOA Speer Electronics, Inc.) within the same RK73G series. The primary distinction is product status: the substitute is classified as "Active," whereas the original part is "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1003D is a direct functional equivalent to the RK73G1HTTC1003D. Both components are manufactured by KOA Speer Electronics, Inc., belong to the same RK73G series, and share identical electrical and mechanical specifications. The substitute part maintains full compliance with AEC-Q200 automotive qualification and ROHS3 environmental standards.

The primary distinction is product lifecycle status: the original part is designated "Not For New Designs," while the substitute is classified as "Active." For applications requiring ongoing component procurement, the RK73G1HTTCM1003D is the appropriate selection. Both parts are suitable for automotive applications operating within the -55°C to 155°C temperature range and are compatible with standard surface-mount assembly processes for 0201 package components.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1003D be used as a direct replacement for RK73G1HTTC1003D?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance (100 kOhms), tolerance (±0.5%), power rating (0.05W), package (0201), and automotive qualification (AEC-Q200). The substitute is the active production equivalent.

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

A: This designation indicates the part is in end-of-life phase and is not recommended for new product development. The RK73G1HTTCM1003D, classified as "Active," is the current production alternative.

Q: Are there any differences in thermal or electrical performance between these parts?

A: No. Both parts have identical temperature coefficients (±50ppm/°C), operating temperature ranges (-55°C ~ 155°C), and all other electrical specifications.

Q: Is the 0201 package compatible with standard PCB assembly equipment?

A: Yes. The 0201 (0603 Metric) package is a standard surface-mount component size compatible with modern pick-and-place and reflow assembly processes.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both the RK73G1HTTC1003D and RK73G1HTTCM1003D are AEC-Q200 qualified and ROHS3 compliant, meeting automotive industry standards.
