Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1608N-1373-B-T1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 137 kOhms
• Package format: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Temperature coefficient: ±10ppm/°C or ±25ppm/°C
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Active or Obsolete
• Manufacturer: Different manufacturers permitted if all electrical and mechanical specifications align

Substitute parts must maintain identical electrical performance within the specified operating envelope and meet all automotive and environmental compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

RG1608N-1373-B-T5 (Direct Susumu Equivalent)

This part is the direct equivalent to the RG1608N-1373-B-T1, differing only in packaging format (Tape & Reel versus bulk). All electrical specifications, tolerance, temperature coefficient, and automotive qualifications are identical. The RG1608N-1373-B-T5 carries active product status, ensuring long-term availability and supply chain continuity. This is the primary substitute for applications requiring identical performance characteristics.

RG1608N-1373-W-T1 (Susumu Upgrade)

This part offers enhanced tolerance specification (±0.05% versus ±0.1%), providing superior precision while maintaining all other electrical and mechanical parameters. The RG1608N-1373-W-T1 is suitable for applications requiring tighter resistance tolerance. Active product status supports ongoing procurement. Selection of this upgrade is appropriate when circuit design specifications demand higher precision than the original ±0.1% tolerance.

ERA-3AEB1373V (Panasonic Cross-Manufacturer Equivalent)

This Panasonic component provides functional equivalence with identical resistance, tolerance, power rating, and package format. The ERA-3AEB1373V maintains AEC-Q200 automotive qualification and ROHS3 compliance. The temperature coefficient specification (±25ppm/°C) is less stringent than the Susumu alternatives (±10ppm/°C), and the maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for Susumu parts. Active product status and high inventory availability support procurement flexibility. This part is suitable for applications where the broader temperature coefficient and slightly increased height are within design tolerances.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-1373-B-T5 be used as a direct replacement for RG1608N-1373-B-T1?

A: Yes. The RG1608N-1373-B-T5 is electrically and mechanically identical to the RG1608N-1373-B-T1. The only difference is packaging format (Tape & Reel versus bulk). Both parts meet identical electrical specifications, tolerance, temperature coefficient, and automotive qualifications.

Q: What is the advantage of RG1608N-1373-W-T1 over the original part?

A: The RG1608N-1373-W-T1 provides tighter tolerance specification at ±0.05% compared to the original ±0.1%. All other parameters remain identical. This upgrade is appropriate for precision-critical applications requiring superior resistance accuracy.

Q: Can ERA-3AEB1373V be substituted in all applications?

A: ERA-3AEB1373V is functionally equivalent for most applications. However, the temperature coefficient is ±25ppm/°C compared to ±10ppm/°C for Susumu parts, and the maximum seated height is 0.022" (0.55mm) versus 0.020" (0.50mm). Verify that these specifications are acceptable for your specific circuit design and PCB layout constraints.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, meeting the same automotive reliability standards as the original RG1608N-1373-B-T1.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (RG1608N-1373-B-T1) is supplied in loose form, while Tape & Reel (TR) packaging (RG1608N-1373-B-T5, RG1608N-1373-W-T1, ERA-3AEB1373V) is supplied on continuous tape for automated assembly. Electrical and mechanical specifications are identical; packaging format selection depends on manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant and meet environmental regulatory requirements equivalent to the original part.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the original and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
