Substitute Part Grouping Explanation

Substitution of the RG1608P-102-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Resistance value: 1 kOhms (exact match required)
Package type: 0603 (1608 Metric) (physical and electrical compatibility)
Power rating: 0.1W minimum (equal or greater)
Composition: Thin film (electrical performance characteristics)
Operating temperature range: -55°C to 155°C minimum (environmental compatibility)
AEC-Q200 automotive qualification (reliability standard)
RoHS3 compliance (regulatory requirement)

Tolerance Consideration: Tolerance specifications determine substitution hierarchy. The RG1608P-102-C-T5 specifies ±0.25% tolerance. Substitute parts with equal or tighter tolerance (lower numerical value) are direct functional replacements. Parts with looser tolerance do not qualify as substitutes for this application.

Temperature Coefficient: Temperature coefficient values (±25ppm/°C, ±10ppm/°C, ±5ppm/°C) indicate thermal stability performance. Lower values represent superior thermal performance but do not prevent substitution when other parameters align.

Packaging Format: Packaging format (Tape & Reel, Cut Tape & Digi-Reel) affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Substitute (Exact Tolerance Match): The RT0603CRD071KL from YAGEO provides direct electrical equivalence to the RG1608P-102-C-T5, matching the ±0.25% tolerance specification and ±25ppm/°C temperature coefficient. This part is active in production, ROHS3 compliant, and maintains identical 0603 package dimensions and 0.1W power rating. Selection of this part eliminates design modification requirements.

Susumu RG Series Alternatives (Tighter Tolerance): The RG1608P-102-B-T5, RG1608P-102-P-T1, and RG1608P-102-W-T1 represent active Susumu alternatives with tolerance specifications tighter than the original ±0.25%. These parts maintain the ±25ppm/°C temperature coefficient of the RG1608P series and are suitable for applications where improved tolerance performance is acceptable or beneficial. The RG1608P-102-B-T5 offers the most direct substitution with ±0.1% tolerance and Cut Tape & Digi-Reel packaging.

Susumu RG Series with Enhanced Thermal Stability (RG1608N and RG1608V): The RG1608N series (±10ppm/°C) and RG1608V series (±5ppm/°C) provide superior temperature coefficient performance compared to the original part. These alternatives are suitable for applications requiring enhanced thermal stability. The RG1608N-102-B-T5 and RG1608V-102-B-T5 offer ±0.1% tolerance with improved thermal characteristics.

Compliance Verification: All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating. All parts operate across the -55°C to 155°C temperature range specified for the original component.

Frequently Asked Questions (FAQ)

Q: Can the RT0603CRD071KL replace the RG1608P-102-C-T5 without design modification?

A: Yes. The RT0603CRD071KL matches the critical electrical parameters: 1 kOhms resistance, ±0.25% tolerance, 0.1W power rating, 0603 package, and ±25ppm/°C temperature coefficient. Both parts are thin film composition with identical operating temperature range (-55°C to 155°C) and RoHS3 compliance. Physical dimensions and height specifications are compatible.

Q: What is the difference between RG1608P and RG1608N series parts?

A: The primary difference is temperature coefficient specification. RG1608P series specifies ±25ppm/°C, while RG1608N series specifies ±10ppm/°C. Both series maintain identical resistance values, power ratings, and 0603 package dimensions. The RG1608N series provides superior thermal stability across the operating temperature range.

Q: What is the difference between RG1608N and RG1608V series parts?

A: The RG1608V series provides enhanced temperature coefficient performance at ±5ppm/°C compared to RG1608N at ±10ppm/°C. Both series are active products with identical resistance, tolerance, power rating, and package specifications. Selection between these series depends on application thermal stability requirements.

Q: Are all substitute parts available in the same packaging format?

A: No. The original RG1608P-102-C-T5 packaging format is not specified in available data. Substitute parts are available in Tape & Reel (TR) or Cut Tape & Digi-Reel® formats. The RG1608P-102-B-T5 is available in Cut Tape & Digi-Reel format, while most other alternatives use Tape & Reel packaging. Packaging format selection depends on assembly process requirements.

Q: Can a part with tighter tolerance (lower percentage) replace the RG1608P-102-C-T5?

A: Yes. Parts with tighter tolerance specifications (±0.1%, ±0.05%, ±0.02%) are functionally superior and directly compatible with applications designed for ±0.25% tolerance. Tighter tolerance parts provide improved accuracy and stability without requiring design modification.

Q: Is the RG1608P-102-C-T5 still available for purchase?

A: No. The RG1608P-102-C-T5 is marked as obsolete. Active alternatives from Susumu (RG1608P, RG1608N, and RG1608V series) and YAGEO (RT0603CRD071KL) are available for new designs and replacement applications.

Q: What does AEC-Q200 qualification mean for automotive applications?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. All substitute parts listed maintain this qualification, confirming suitability for automotive and high-reliability applications requiring proven quality and reliability standards.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions. Compliance status is consistent across all alternatives.
