ROX1SJ75R Equivalent & Substitute Parts

Part Overview

The ROX1SJ75R is a 75 Ohm, 1W through-hole axial resistor manufactured by TE Connectivity Passive Product. This metal oxide film resistor is designed for applications requiring flame-proof and pulse-withstanding characteristics with safety ratings. The component is currently in active production status with 854 pieces available in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package type. Alternative sources provide equivalent performance for applications where supply continuity or inventory availability requires component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ROX1SJ75R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Metal Oxide Film (exact match required)

Mechanical Compatibility Requirements:

• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 Compliant status (required for regulatory alignment)

The substitute part RSF100JB-73-75R meets all electrical and mechanical equivalence criteria. Both components share identical resistance, tolerance, power rating, composition, and axial package configuration with two terminations. Both maintain ROHS3 compliance status, ensuring regulatory compatibility in applications requiring RoHS certification.

Engineering Selection Recommendations

ROX1SJ75R Selection Criteria: The ROX1SJ75R is appropriate for applications where the compact axial form factor (3.50mm diameter x 10.00mm length) is required and operating temperatures do not exceed 130°C. This component is suitable for standard industrial and commercial applications with ROHS3 compliance requirements. The TE Connectivity Passive Product series provides established supply chain integration for OEM applications.

RSF100JB-73-75R Selection Criteria: The RSF100JB-73-75R is appropriate for applications requiring extended operating temperature capability up to 235°C while maintaining identical electrical specifications. The larger physical dimensions (4.50mm diameter x 11.50mm length) accommodate higher thermal dissipation requirements. This YAGEO component is suitable for high-temperature industrial applications with ROHS3 compliance requirements. The higher inventory level (5033 pieces) provides enhanced supply availability for high-volume production requirements.

Substitution Compatibility: Both components are electrically and mechanically equivalent for applications operating within the ROX1SJ75R temperature range of -55°C to 130°C. The RSF100JB-73-75R provides a direct functional substitute with extended temperature capability. Physical dimension differences require PCB layout verification to confirm mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can RSF100JB-73-75R replace ROX1SJ75R in all applications?

A: RSF100JB-73-75R provides electrical and functional equivalence for all applications operating within the -55°C to 130°C temperature range. Physical dimensions differ (RSF100JB-73-75R is larger), requiring PCB layout verification to confirm mechanical fit. Both components maintain identical resistance, tolerance, power rating, and ROHS3 compliance.

Q: What are the physical dimension differences between these components?

A: ROX1SJ75R measures 0.138" diameter x 0.394" length (3.50mm x 10.00mm). RSF100JB-73-75R measures 0.177" diameter x 0.453" length (4.50mm x 11.50mm). The substitute part is larger in both diameter and length, which may affect PCB routing and component spacing.

Q: Are both components RoHS compliant?

A: Yes, both ROX1SJ75R and RSF100JB-73-75R are ROHS3 compliant, meeting regulatory requirements for restricted substance elimination in electronic components.

Q: What is the temperature coefficient difference between these parts?

A: ROX1SJ75R specifies a temperature coefficient of ±350ppm/°C. RSF100JB-73-75R does not provide temperature coefficient data in the available specifications.

Q: Which component should be selected for high-temperature applications?

A: RSF100JB-73-75R supports operating temperatures up to 235°C, compared to ROX1SJ75R maximum of 130°C. For applications exceeding 130°C, RSF100JB-73-75R is the appropriate selection.

Q: What packaging differences exist between these components?

A: ROX1SJ75R is supplied in Tape & Box (TB) packaging format. RSF100JB-73-75R is supplied in Bulk packaging format. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Are there inventory considerations for component selection?

A: ROX1SJ75R has 854 pieces in current stock. RSF100JB-73-75R has 5033 pieces in current stock. Higher inventory availability for RSF100JB-73-75R supports extended production runs and reduces lead time risk.
