Substitute Part Grouping Explanation

Substitution of the RG3216P-73R2-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 73.2 Ohms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)

Mechanical Parameters:

• Package format: 1206 (3216 Metric) (exact match required)
• Physical dimensions: 0.126" L × 0.063" W (3.20mm × 1.60mm) (exact match required)
• Height seated maximum: 0.020" (0.50mm) (exact match required)

Material & Composition:

• Thin film construction (exact match required)
• Anti-sulfur coating (exact match required)

Compliance & Ratings:

• AEC-Q200 automotive qualification (exact match required)
• ROHS3 compliance (exact match required)
• Moisture Sensitivity Level 1 (exact match required)

Substitute parts must maintain identical electrical performance, physical form factor, and automotive-grade reliability standards. Variations in temperature coefficient or product status do not disqualify substitution when all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

The RG3216N-73R2-W-T1 is a direct functional equivalent to the RG3216P-73R2-W-T1 for applications requiring 73.2 Ohm precision thin film resistors in 1206 package format with automotive AEC-Q200 qualification.

Substitution Basis:

All critical electrical, mechanical, and compliance parameters are identical between the main part and substitute. Both components meet ROHS3 compliance, maintain AEC-Q200 automotive ratings, and deliver equivalent performance across the -55°C to 155°C operating temperature range.

Product Status Advantage:

The RG3216N-73R2-W-T1 carries active product status, ensuring ongoing availability and supply chain continuity. The main part RG3216P-73R2-W-T1 is obsolete, making the substitute the preferred selection for new designs and ongoing production requirements.

Temperature Coefficient Consideration:

The substitute part exhibits a superior temperature coefficient of ±10ppm/°C compared to the main part's ±25ppm/°C. This represents improved thermal stability and does not restrict substitution; it qualifies as a performance enhancement within the same functional category.

Frequently Asked Questions (FAQ)

Q: Can the RG3216N-73R2-W-T1 be used as a direct replacement for the RG3216P-73R2-W-T1 in existing designs?

A: Yes. Both parts are manufactured by Susumu, share identical resistance (73.2 Ohms), tolerance (±0.05%), power rating (0.25W), package format (1206), and AEC-Q200 automotive qualification. Electrical and mechanical compatibility is complete.

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

A: The primary difference is product status. The RG3216P-73R2-W-T1 is obsolete, while the RG3216N-73R2-W-T1 is active. The RG3216N also features an improved temperature coefficient (±10ppm/°C versus ±25ppm/°C), providing enhanced thermal stability.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG3216P-73R2-W-T1 and RG3216N-73R2-W-T1 carry AEC-Q200 automotive qualification and anti-sulfur coating, meeting automotive reliability and environmental resistance requirements.

Q: Does the packaging format differ between these parts?

A: The main part RG3216P-73R2-W-T1 is supplied in standard packaging, while the substitute RG3216N-73R2-W-T1 is supplied in Tape & Reel (TR) format. Both maintain identical 1206 (3216 Metric) package dimensions and form factor. Tape & Reel packaging is standard for high-volume production and automated assembly.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.

Q: What is the inventory status for each part?

A: The RG3216P-73R2-W-T1 (obsolete) has 1,144 pieces in stock. The RG3216N-73R2-W-T1 (active) has 737 pieces in stock. For ongoing production, the active part is the recommended selection.
