Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3APB393V is determined by the following mandatory parameters: resistance value (39 kOhms), package type (0603/1608 Metric), power rating (0.1W), composition (thin film), and automotive qualification (AEC-Q200). All substitute parts must maintain these core specifications to ensure functional and mechanical compatibility.

The substitute parts are grouped as follows:

Upgrade Substitutes (Panasonic ERA-3A Series): ERA-3ARB393V and ERA-3ARW393V maintain identical resistance, package, power rating, and automotive qualification. These parts offer improved temperature coefficient performance (±10ppm/°C versus ±15ppm/°C) and enhanced tolerance specifications. ERA-3ARW393V provides the tightest tolerance at ±0.05%.

Direct Substitute (Cross-Manufacturer): RG1608N-393-W-T1 from Susumu matches all core electrical and mechanical parameters with the addition of anti-sulfur coating for enhanced environmental protection. Temperature coefficient and tolerance specifications are equivalent to the ERA-3ARB393V upgrade option.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full AEC-Q200 automotive qualification with ROHS3 compliance, ensuring regulatory and quality standard alignment with the ERA-3APB393V.

ERA-3ARB393V provides direct functional substitution with improved temperature coefficient performance while maintaining Panasonic manufacturing continuity and identical package dimensions.

ERA-3ARW393V offers enhanced tolerance specification (±0.05% versus ±0.1%) for applications requiring tighter resistance accuracy, with equivalent temperature coefficient improvement.

RG1608N-393-W-T1 from Susumu provides cross-manufacturer substitution with anti-sulfur coating for enhanced corrosion resistance in harsh automotive environments. The seated height is 0.020" (0.50mm) compared to 0.022" (0.55mm) for Panasonic parts, which may require PCB layout verification for applications with height-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can ERA-3ARB393V be used as a direct replacement for ERA-3APB393V?

A: Yes. Both parts share identical resistance value, tolerance, power rating, package type, and AEC-Q200 automotive qualification. ERA-3ARB393V offers improved temperature coefficient (±10ppm/°C versus ±15ppm/°C) with no dimensional or functional incompatibility.

Q: What is the primary difference between ERA-3ARW393V and ERA-3APB393V?

A: ERA-3ARW393V provides tighter tolerance specification at ±0.05% compared to ±0.1% for the ERA-3APB393V. Both maintain identical package dimensions, power rating, and automotive qualification. The improved tolerance makes ERA-3ARW393V suitable for precision circuit applications.

Q: Is RG1608N-393-W-T1 mechanically compatible with ERA-3APB393V?

A: RG1608N-393-W-T1 is mechanically compatible with one dimensional consideration: the seated height is 0.020" (0.50mm) versus 0.022" (0.55mm) for the ERA-3APB393V. This 0.002" (0.05mm) difference is negligible for most PCB designs but should be verified for applications with strict height constraints or automated assembly specifications.

Q: Why would I select RG1608N-393-W-T1 over Panasonic alternatives?

A: RG1608N-393-W-T1 includes anti-sulfur coating for enhanced environmental protection in harsh automotive conditions. This feature, combined with equivalent electrical specifications and higher inventory availability (25961 units), makes it suitable for applications requiring corrosion resistance.

Q: Are all substitute parts ROHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitute parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, ensuring regulatory alignment and quality standards equivalent to the ERA-3APB393V.

Q: What is the moisture sensitivity level for all parts?

A: All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.
