Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG3216P-4322-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 43.2 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)

Mechanical Parameters:

• Package type: 1206 (3216 Metric) (exact match required)
• Composition: Thin Film (exact match required)

Compliance & Environmental Parameters:

• Automotive AEC-Q200 qualification (required)
• Anti-sulfur coating (required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

Substitute parts must satisfy all parameters listed above. Variations in temperature coefficient, packaging format (tape & reel vs. bulk), or product status do not disqualify substitution when all electrical, mechanical, and compliance criteria are met.

Parameter Comparison

Engineering Selection Recommendations

The RG3216N-4322-W-T1 offers improved temperature coefficient performance (±10ppm/°C versus ±25ppm/°C), providing enhanced stability across the operating temperature range.

Both parts maintain full compliance with ROHS3 regulations, REACH requirements, and automotive reliability standards. The RG3216N-4322-W-T1 is available in tape & reel packaging format, which is standard for high-volume manufacturing and automated assembly processes.

For applications requiring the RG3216P-4322-W-T1 specification, the RG3216N-4322-W-T1 is the appropriate active substitute that maintains full functional and physical compatibility while ensuring continued supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the RG3216N-4322-W-T1 be used as a direct replacement for the RG3216P-4322-W-T1?

A: Yes. Both components share identical electrical specifications (43.2 kOhms ±0.05%, 0.25W), mechanical dimensions (1206 package), composition (thin film), and automotive AEC-Q200 qualification. The RG3216N-4322-W-T1 is a direct substitute suitable for PCB assembly without design modification.

Q: What is the difference between the RG3216P and RG3216N series?

A: The primary differences are product status and temperature coefficient. The RG3216P-4322-W-T1 is obsolete with a temperature coefficient of ±25ppm/°C. The RG3216N-4322-W-T1 is active production with an improved temperature coefficient of ±10ppm/°C. All other electrical and mechanical parameters are identical.

Q: Are there packaging format differences between these parts?

A: The RG3216P-4322-W-T1 is supplied in standard packaging format. The RG3216N-4322-W-T1 is supplied in tape & reel (TR) format, which is the standard packaging for automated surface mount assembly. Both formats contain the same component specification and are compatible with standard pick-and-place equipment.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RG3216P-4322-W-T1 and RG3216N-4322-W-T1 carry AEC-Q200 automotive qualification, anti-sulfur coating, and are rated for -55°C to 155°C operating temperature. Both are ROHS3 compliant and have Moisture Sensitivity Level 1 (unlimited shelf life).

Q: Why should I transition from the RG3216P to the RG3216N?

A: The RG3216P-4322-W-T1 is obsolete and subject to supply discontinuation. The RG3216N-4322-W-T1 is the active equivalent that ensures long-term supply availability, maintains full specification compatibility, and provides improved temperature stability through its superior temperature coefficient specification.

Q: Are the physical dimensions identical?

A: Yes. Both components are 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.020" (0.50mm). They are mechanically interchangeable on PCB layouts.
