Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1608V-751-B-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 750 Ohms (exact match required)
• Power rating: 0.1W minimum
• Temperature coefficient: ±5ppm/°C or better
• Operating temperature range: Must support -55°C to 155°C minimum

Mechanical Parameters:

• Package: 0603 (1608 Metric) form factor
• Physical dimensions: 0.063" L x 0.031" W maximum
• Height seated: 0.020" (0.50mm) maximum

Compliance & Certification:

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Thin film composition
• Anti-sulfur feature

Substitute parts are classified into two categories:

Direct Substitutes: Parts with identical electrical specifications (750 Ohms ±0.1%, 0.1W, ±5ppm/°C) and mechanical compatibility. These include RG1608V-751-B-T5 (Susumu, active status) and TNPU0603750RBZEN00 (Vishay Dale, active status).

Upgrade Substitutes: Parts with superior tolerance specifications (±0.05% or ±0.02%) while maintaining all other electrical and mechanical parameters. These include RG1608V-751-W-T1 (±0.05%) and RG1608V-751-P-T1 (±0.02%), both Susumu active products.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Electrical & Mechanical Equivalence):

RG1608V-751-B-T5 (Susumu) is the primary direct substitute for RG1608V-751-B-T1. Both parts share identical electrical specifications (750 Ohms ±0.1%, 0.1W, ±5ppm/°C) and mechanical dimensions. The RG1608V-751-B-T5 is in active production status with 700 units in stock. The only difference is packaging format (Tape & Reel versus bulk), which does not affect electrical or mechanical performance.

TNPU0603750RBZEN00 (Vishay Dale) is an alternative direct substitute with identical tolerance (±0.1%) and power rating (0.1W). This part is in active production status with 666 units in stock. Physical dimensions are within acceptable tolerance (0.063" L x 0.033" W versus 0.063" L x 0.031" W, and height 0.022" versus 0.020"). The operating temperature range is -55°C to 125°C, which is 30°C lower than the original part's upper limit. This part includes moisture-resistant coating in addition to anti-sulfur protection.

Upgrade Substitution (Enhanced Tolerance):

RG1608V-751-W-T1 (Susumu) provides superior tolerance specification (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. This part is in active production status with 685 units in stock. Upgrade substitution is applicable when circuit design requires tighter tolerance control.

RG1608V-751-P-T1 (Susumu) provides the highest tolerance specification (±0.02%) among available substitutes. This part is in active production status with 995 units in stock. Upgrade substitution is applicable for precision circuit applications requiring the tightest tolerance control.

Compliance Verification:

All substitute parts maintain AEC-Q200 automotive qualification, RoHS3 compliance, and anti-sulfur coating. All parts are rated for MSL 1 (Unlimited moisture sensitivity level). Selection between substitutes should prioritize active production status and inventory availability for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RG1608V-751-B-T5 be used as a direct replacement for RG1608V-751-B-T1?

A: Yes. RG1608V-751-B-T5 is a direct electrical and mechanical equivalent. Both parts have 750 Ohms ±0.1% resistance, 0.1W power rating, ±5ppm/°C temperature coefficient, and 0603 package form factor. The primary difference is packaging format (Tape & Reel versus bulk), which does not affect circuit performance. RG1608V-751-B-T5 is in active production status, making it the recommended substitute for the obsolete RG1608V-751-B-T1.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (RG1608V-751-B-T5 and TNPU0603750RBZEN00) have identical electrical specifications to the original part, including ±0.1% tolerance. Upgrade substitutes (RG1608V-751-W-T1 with ±0.05% and RG1608V-751-P-T1 with ±0.02%) offer tighter tolerance specifications. Upgrade substitutes are electrically compatible but provide enhanced precision for applications requiring stricter tolerance control.

Q: Is TNPU0603750RBZEN00 compatible with the original RG1608V-751-B-T1?

A: TNPU0603750RBZEN00 is electrically compatible with identical 750 Ohms ±0.1% specifications and 0.1W power rating. Physical dimensions are within acceptable tolerance for 0603 package form factor. The operating temperature range is -55°C to 125°C, which is 30°C lower than the original part's -55°C to 155°C range. This part is suitable for applications operating within the -55°C to 125°C range. TNPU0603750RBZEN00 includes moisture-resistant coating in addition to anti-sulfur protection.

Q: Can I use RG1608V-751-W-T1 or RG1608V-751-P-T1 in place of RG1608V-751-B-T1?

A: Yes. Both RG1608V-751-W-T1 (±0.05% tolerance) and RG1608V-751-P-T1 (±0.02% tolerance) are electrically and mechanically compatible with RG1608V-751-B-T1. These parts maintain all other specifications including 750 Ohms resistance, 0.1W power rating, ±5ppm/°C temperature coefficient, and 0603 package form factor. These upgrade substitutes provide superior tolerance performance and are suitable for precision applications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed (RG1608V-751-B-T5, RG1608V-751-W-T1, RG1608V-751-P-T1, and TNPU0603750RBZEN00) maintain AEC-Q200 automotive qualification, anti-sulfur coating, and RoHS3 compliance. All parts are suitable for automotive applications.

Q: What is the inventory status of substitute parts?

A: RG1608V-751-B-T5 has 700 units in stock. RG1608V-751-W-T1 has 685 units in stock. RG1608V-751-P-T1 has 995 units in stock. TNPU0603750RBZEN00 has 666 units in stock. All substitute parts are in active production status, ensuring long-term availability.

Q: Does packaging format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is standard for automated assembly processes. The original RG1608V-751-B-T1 was supplied in bulk format, while all substitute parts are supplied in Tape & Reel format. This difference is purely logistical and does not impact circuit functionality.
