Substitute Part Grouping Explanation

Substitution eligibility for the RG3216P-4752-B-T1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 47.5 kOhms (exact match)
• Tolerance: ±0.1% (exact match)
• Temperature coefficient: ±25ppm/°C (exact match)
• Composition: Thin film technology

Mechanical Equivalence Requirements:

• Package format: 1206 (3216 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) (exact match)

Compliance & Certification Requirements:

• Automotive AEC-Q200 rating (mandatory)
• RoHS3 compliance (mandatory)
• Moisture Sensitivity Level 1 (mandatory)

Substitution Allowances:

• Power rating may exceed the original specification (0.25W minimum)
• Operating temperature range may exceed the original specification (-55°C ~ 155°C minimum)
• Height variation within standard package tolerances is acceptable
• Anti-sulfur and moisture-resistant features are optional enhancements

The identified substitute parts meet all mandatory equivalence criteria and are therefore direct functional replacements for the RG3216P-4752-B-T1 in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RG3216P-4752-B-T1 (Susumu), ERA-8AEB4752V (Panasonic), and TNPW120647K5BEEA (Vishay Dale)—are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Each part satisfies the mandatory electrical and mechanical equivalence criteria for direct substitution.

Susumu RG3216P-4752-B-T1: Primary specification with anti-sulfur coating. Operates within -55°C ~ 155°C range at 0.25W power rating. Suitable for standard automotive applications with moderate thermal environments.

Panasonic ERA-8AEB4752V: Direct electrical equivalent with identical power rating (0.25W) and operating temperature range (-55°C ~ 155°C). Maintains anti-sulfur and moisture-resistant features. Height specification (0.028" max) is within acceptable package tolerance variation.

Vishay Dale TNPW120647K5BEEA: Electrical equivalent with enhanced power rating (0.52W) and extended operating temperature range (-55°C ~ 175°C). Includes anti-sulfur and moisture-resistant features. Height specification (0.026" max) is within acceptable package tolerance variation. Suitable for applications requiring higher thermal headroom or elevated ambient temperature operation.

Selection between these parts is determined by application-specific thermal requirements, supply chain availability, and design margin preferences. All three parts are functionally interchangeable within the specified electrical and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4752V replace RG3216P-4752-B-T1 in all applications?

A: Yes. The ERA-8AEB4752V maintains identical electrical specifications (47.5 kOhms ±0.1%, ±25ppm/°C), power rating (0.25W), operating temperature range (-55°C ~ 155°C), and package format (1206). Both parts carry AEC-Q200 qualification and ROHS3 compliance. Physical height variation (0.028" vs 0.020" max) is within standard 1206 package tolerances and does not affect PCB assembly compatibility.

Q: What is the advantage of TNPW120647K5BEEA over the original RG3216P-4752-B-T1?

A: The TNPW120647K5BEEA provides two enhancements: (1) higher power dissipation capability (0.52W vs 0.25W), enabling operation in higher thermal stress environments, and (2) extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), supporting applications in elevated ambient temperature conditions. Electrical specifications remain identical.

Q: Are there any height clearance concerns when substituting these parts?

A: The RG3216P-4752-B-T1 has a maximum seated height of 0.020" (0.50mm). Substitute parts have slightly higher maximum heights: ERA-8AEB4752V at 0.028" (0.70mm) and TNPW120647K5BEEA at 0.026" (0.65mm). These variations remain within the 1206 package specification tolerance. Verify PCB layout clearance if height-constrained applications are present.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 (unlimited). They are suitable for automotive and industrial applications requiring automotive-grade component certification.

Q: Can TNPW120647K5BEEA be used in place of RG3216P-4752-B-T1 in a 0.25W circuit design?

A: Yes. The TNPW120647K5BEEA is rated for 0.52W power dissipation, which exceeds the 0.25W requirement. Using a higher-rated component in a lower-power application introduces no functional or reliability concerns. The component will operate well within its thermal limits.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision thin film resistor construction. All three substitute parts maintain this tolerance specification, ensuring consistent electrical performance across production batches and temperature variations. This precision is critical for applications requiring stable circuit performance, such as precision measurement and signal conditioning circuits.

Q: Are packaging and tape specifications identical across all three parts?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging format, standard for automated PCB assembly. The 1206 (3216 Metric) package format and two-termination configuration are identical across all parts, ensuring compatibility with existing pick-and-place equipment and assembly processes.
