Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3APB512V is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 5.1 kOhms
• Package type: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Automotive compliance: AEC-Q200
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.063" L × 0.031" W maximum

Allowable Variations:

• Tolerance: Equal to or tighter than ±0.1%
• Temperature coefficient: Equal to or better than ±15ppm/°C
• Height (seated): Up to 0.022" (0.55mm)
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters align

Parts meeting these criteria are classified as direct substitutes. Parts with improved specifications (tighter tolerance, lower temperature coefficient) are classified as upgrades.

Parameter Comparison

Engineering Selection Recommendations

ERA-3ARB512V (Panasonic): Direct substitute with equivalent electrical performance. Temperature coefficient improved to ±10ppm/°C. All mechanical and compliance parameters identical. Higher inventory availability (8,381 units) supports supply chain continuity.

ERA-3ARW512V (Panasonic): Upgrade substitute with tighter tolerance (±0.05% vs ±0.1%) and improved temperature coefficient (±10ppm/°C). Suitable for applications requiring enhanced precision. Lower inventory (932 units) may impact lead time.

RG1608N-512-W-T1 (Susumu): Upgrade substitute with ±0.05% tolerance and ±10ppm/°C temperature coefficient. Includes anti-sulfur feature. Seated height 0.020" (0.50mm) is 0.002" lower than ERA-3APB512V. All AEC-Q200 and ROHS3 compliance maintained. Highest inventory availability (8,233 units).

All substitute parts maintain identical resistance value, power rating, package type, operating temperature range, and automotive compliance ratings. Selection should be based on tolerance requirements, temperature stability needs, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-3ARB512V replace ERA-3APB512V in existing designs? A: Yes. ERA-3ARB512V is a direct substitute with identical electrical specifications and package dimensions. The improved temperature coefficient (±10ppm/°C vs ±15ppm/°C) provides enhanced stability without requiring circuit modifications.

Q: What is the difference between ERA-3ARW512V and ERA-3APB512V? A: ERA-3ARW512V offers tighter tolerance (±0.05% vs ±0.1%) and lower temperature coefficient (±10ppm/°C vs ±15ppm/°C). Both maintain identical resistance, power rating, package, and operating temperature range. Selection depends on circuit precision requirements.

Q: Is RG1608N-512-W-T1 compatible with ERA-3APB512V? A: Yes. RG1608N-512-W-T1 is compatible with identical resistance, power rating, package dimensions, and AEC-Q200 compliance. The seated height is 0.002" lower (0.020" vs 0.022"), which is within acceptable PCB assembly tolerances. The anti-sulfur feature provides additional environmental protection.

Q: Do all substitute parts meet AEC-Q200 automotive requirements? A: Yes. ERA-3ARB512V, ERA-3ARW512V, and RG1608N-512-W-T1 all carry AEC-Q200 ratings and are suitable for automotive applications requiring this qualification.

Q: Are there any RoHS or environmental compliance differences? A: No. All parts including ERA-3APB512V are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Environmental compliance is equivalent across all options.

Q: Which substitute offers the best value for high-precision applications? A: ERA-3ARW512V and RG1608N-512-W-T1 both provide ±0.05% tolerance and ±10ppm/°C temperature coefficient. RG1608N-512-W-T1 offers higher inventory availability and anti-sulfur protection. Selection should consider specific circuit requirements and supply chain priorities.
