Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1608P-393-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 39 kOhms
• Tolerance: ±0.05%
• Power rating: 0.1W (1/10W)
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200

Mechanical Parameters:

• Package type: 0603 (1608 Metric)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Number of terminations: 2
• Composition: Thin Film

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these criteria. Temperature coefficient variations (±25ppm/°C vs. ±10ppm/°C) and anti-sulfur feature presence do not preclude substitution but represent performance enhancements or feature differences within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

RG1608N-393-W-T1 (Susumu): This direct equivalent from the same manufacturer shares identical electrical specifications and package dimensions with the primary part. The RG1608N variant offers improved temperature coefficient performance (±10ppm/°C vs. ±25ppm/°C) while maintaining all compliance certifications. This part is suitable for direct substitution with enhanced thermal stability characteristics. Higher inventory availability (25,961 pcs) supports supply chain continuity.

ERA-3ARW393V (Panasonic Electronic Components): This cross-manufacturer substitute meets all critical electrical and mechanical parameters. The part maintains AEC-Q200 automotive qualification and ROHS3 compliance. The seated height specification (0.022" maximum vs. 0.020" maximum) represents a minor dimensional variance within typical PCB assembly tolerances for 0603 packages. Temperature coefficient performance (±10ppm/°C) matches the RG1608N variant. This option provides supply diversification across manufacturers while preserving functional equivalence.

All three parts are active products with unlimited moisture sensitivity rating and full automotive qualification, supporting deployment in high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-393-W-T1 replace RG1608P-393-W-T1 in existing designs?

A: Yes. Both parts share identical resistance (39 kOhms), tolerance (±0.05%), power rating (0.1W), package (0603), and operating temperature range (-55°C ~ 155°C). The RG1608N variant provides superior temperature coefficient performance (±10ppm/°C vs. ±25ppm/°C). Physical dimensions and compliance certifications are equivalent.

Q: What is the difference between the Susumu RG1608P and RG1608N variants?

A: The primary difference is temperature coefficient specification. RG1608P is rated at ±25ppm/°C, while RG1608N is rated at ±10ppm/°C. The RG1608P includes anti-sulfur coating as a specified feature. Both maintain identical electrical ratings, package type, and automotive qualification.

Q: Is ERA-3ARW393V mechanically compatible with the original part?

A: Yes, with a minor dimensional note. The ERA-3ARW393V seated height maximum is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the RG1608P-393-W-T1. This 0.002" difference is within standard PCB assembly tolerances for 0603 package components and does not affect functional compatibility or board layout in typical applications.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. RG1608P-393-W-T1, RG1608N-393-W-T1, and ERA-3ARW393V all carry AEC-Q200 automotive qualification and are suitable for automotive and high-reliability applications.

Q: What is the moisture sensitivity rating for these parts?

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

Q: Can I use ERA-3ARW393V in space-constrained PCB layouts?

A: The ERA-3ARW393V has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the Susumu parts. In applications with strict height constraints, verify PCB assembly specifications. For standard applications, this variance is accommodated within typical component placement tolerances.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RG1608P-393-W-T1, RG1608N-393-W-T1, and ERA-3ARW393V are all ROHS3 compliant and REACH unaffected.
