Substitute Part Grouping Explanation

Substitution of the RPC2512JT620R is based on the following critical parameters that must remain constant or improve:

• Resistance value: 620 Ohms (exact match required)
• Package / Case: 2512 (6432 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability)
• Operating Temperature Range: -55°C ~ 155°C (environmental compatibility)
• Automotive Rating: AEC-Q200 (compliance requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Substitute parts may feature improved tolerance (tighter than ±5%) or higher power rating (greater than 1.5W) without compromising the core electrical and mechanical specifications. All substitute parts must maintain identical package dimensions and automotive qualification status.

Parameter Comparison

Engineering Selection Recommendations

The 3521620RFT from TE Connectivity Passive Product qualifies as a direct substitute for the RPC2512JT620R. Both components maintain identical resistance values, package dimensions, thermal characteristics, and automotive AEC-Q200 certification. The substitute part offers enhanced specifications with ±1% tolerance (compared to ±5%) and 2W power rating (compared to 1.5W), providing improved performance margins without introducing incompatibility. Both parts are ROHS3 compliant and feature unlimited moisture sensitivity rating. The substitute part is available in significantly higher inventory quantity (19281 pieces), supporting supply chain continuity. Selection between these parts should be based on application-specific requirements for tolerance precision and power dissipation capacity, with both options meeting all regulatory and automotive compliance standards.

Frequently Asked Questions (FAQ)

Q: Can the 3521620RFT replace the RPC2512JT620R in existing designs?

A: Yes. Both components share identical resistance values, package dimensions (2512 / 6432 Metric), thermal operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical and electrical compatibility is maintained.

Q: What are the key differences between these parts?

A: The substitute part (3521620RFT) features tighter tolerance (±1% versus ±5%) and higher power rating (2W versus 1.5W). These represent performance improvements that do not compromise compatibility.

Q: Are the physical dimensions identical?

A: Dimensions are functionally equivalent. The main part measures 0.250" L x 0.122" W (6.35mm x 3.10mm), while the substitute measures 0.248" L x 0.126" W (6.30mm x 3.20mm). Both share identical maximum seated height of 0.026" (0.65mm), ensuring PCB layout compatibility.

Q: Do both parts meet automotive standards?

A: Yes. Both the RPC2512JT620R and 3521620RFT carry AEC-Q200 qualification and are ROHS3 compliant, meeting automotive industry requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The substitute part (3521620RFT) offers superior tolerance and power rating with higher inventory availability. The main part (RPC2512JT620R) remains a valid choice if existing supply is preferred or if application specifications do not require enhanced performance characteristics.

Q: Are there any thermal or environmental limitations?

A: Both parts operate across identical temperature ranges (-55°C ~ 155°C) with matching temperature coefficients (±100ppm/°C). No environmental limitations differentiate these components.
