Substitute Part Grouping Explanation

Substitution of the RG1608N-910-C-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 91 Ohms
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Variable Parameter (Allows Substitution):

• Tolerance: The RG1608N-910-C-T5 (±0.25%) can be substituted with parts featuring tighter tolerance specifications (±0.1% or ±0.05%), as these represent improved precision grades of the same resistor family.

All substitute parts maintain identical physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and maximum seated height (0.020" / 0.50mm), ensuring mechanical compatibility in PCB layouts.

Engineering Selection Recommendations

RG1608N-910-B-T5 (±0.1% Tolerance)

This substitute provides improved tolerance specification (±0.1% versus ±0.25%) while maintaining all other electrical and mechanical parameters. The part is currently in active production status, ensuring long-term availability and supply chain continuity. This option is suitable for applications where the original obsolete part requires replacement with equivalent or enhanced precision characteristics.

RG1608N-910-W-T5 (±0.05% Tolerance)

This substitute offers the tightest tolerance specification (±0.05%) within the equivalent parts group. All electrical characteristics, thermal performance, and automotive qualification ratings remain identical to the main part. Active product status ensures sustained component availability. This option is appropriate for precision-critical circuit designs or where design margin improvements are beneficial.

Both substitute parts are ROHS3 compliant and maintain AEC-Q200 automotive qualification, supporting applications requiring high-reliability standards and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-910-B-T5 or RG1608N-910-W-T5 be used as direct replacements for RG1608N-910-C-T5?

A: Yes. Both substitute parts are direct replacements. They maintain identical resistance values (91 Ohms), power ratings (0.1W), package configurations (0603), physical dimensions, and all automotive/compliance certifications. The substitutes feature tighter tolerance specifications, which represent improved precision grades of the same component family.

Q: What is the difference between the three parts?

A: The three parts differ only in tolerance specification. RG1608N-910-C-T5 specifies ±0.25% tolerance, RG1608N-910-B-T5 specifies ±0.1% tolerance, and RG1608N-910-W-T5 specifies ±0.05% tolerance. All other parameters—resistance value, power rating, package, thermal characteristics, and certifications—are identical.

Q: Why is the original part marked as obsolete?

A: The RG1608N-910-C-T5 is classified as obsolete, indicating it is no longer in active production. The substitute parts RG1608N-910-B-T5 and RG1608N-910-W-T5 are currently in active production status and provide equivalent or enhanced specifications for new designs and component replacement applications.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts share identical physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and maximum seated height (0.020" / 0.50mm). PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: Do the substitute parts maintain automotive qualification?

A: Yes. Both RG1608N-910-B-T5 and RG1608N-910-W-T5 carry AEC-Q200 automotive qualification and anti-sulfur coating, identical to the original part. Both are ROHS3 compliant and REACH unaffected.

Q: Which substitute should be selected for a new design?

A: Selection depends on circuit tolerance requirements. For applications requiring ±0.25% tolerance, RG1608N-910-B-T5 (±0.1%) provides improved precision with active product status. For precision-critical applications, RG1608N-910-W-T5 (±0.05%) offers the tightest tolerance specification. Both are suitable for automotive and high-reliability applications.

Q: What is the temperature coefficient specification for all three parts?

A: All three parts specify ±10ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C.
