Substitute Part Grouping Explanation

Substitute parts for the RP164PJ751CS are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Electrical Parameters:

• Resistance value: 750 Ohm (exact match required)
• Tolerance: ±5% (exact match required)
• Circuit type: Isolated (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or wider range acceptable)
• Number of resistors: 4 (exact match required)
• Number of pins: 8 (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals (exact match required)
• Size / Dimension: 0.126" L x 0.063" W (3.20mm x 1.60mm) (exact match required)
• Mounting type: Surface Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The RAVF164DJT750R manufactured by Stackpole Electronics Inc meets all substitution criteria and is classified as an active product.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT750R from Stackpole Electronics Inc is the qualified substitute for the RP164PJ751CS. Selection rationale is based on the following factors:

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility with existing design specifications.

Product Status: The RP164PJ751CS is classified as obsolete, creating supply chain risk. The RAVF164DJT750R is classified as active product status, providing assured long-term availability and continued manufacturing support.

Electrical Equivalence: All critical electrical parameters are identical: 750 Ohm resistance, ±5% tolerance, ±200ppm/°C temperature coefficient, and -55°C ~ 155°C operating temperature range. The isolated 4-resistor network configuration with 8-pin arrangement is preserved.

Mechanical Compatibility: Package dimensions, footprint, and mounting characteristics are identical. The 1206 (3216 Metric) convex, long side terminal configuration ensures direct PCB layout compatibility without redesign.

Power Rating Enhancement: The RAVF164DJT750R provides 100mW power per element compared to 62.5mW in the original part, representing a 60% increase in thermal headroom. This enhancement does not create incompatibility and provides additional design margin.

Automotive Qualification: The RAVF164DJT750R carries AEC-Q200 automotive qualification, extending application scope beyond the original part's capabilities.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT750R be used as a direct replacement for RP164PJ751CS in existing designs?

A: Yes. All critical electrical parameters (resistance, tolerance, temperature coefficient, operating temperature range) and mechanical parameters (package, dimensions, pin configuration) are identical. No circuit redesign or PCB layout modification is required.

Q: What is the significance of the higher power rating (100mW vs 62.5mW) in the substitute part?

A: The RAVF164DJT750R's higher power per element rating provides increased thermal capacity. This does not create incompatibility; it provides additional design margin for thermal performance. Existing designs operating within the original 62.5mW specification will operate safely with the substitute part.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited). The RAVF164DJT750R additionally carries AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Q: What is the impact of the obsolete product status of the RP164PJ751CS?

A: Obsolete status indicates Samsung Electro-Mechanics has discontinued manufacturing. The RAVF164DJT750R is active product, ensuring continued availability, manufacturing support, and supply chain reliability for new production and long-term support requirements.

Q: Are the package dimensions and PCB footprints identical?

A: Yes. Both parts use the 1206 (3216 Metric) package with convex, long side terminals. Dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated heights of 0.024" (0.61mm and 0.60mm respectively). PCB footprints are interchangeable without modification.

Q: Can the substitute part be used in automotive applications?

A: The RAVF164DJT750R carries AEC-Q200 automotive qualification. The original RP164PJ751CS does not list automotive qualification. If automotive qualification is required, the substitute part meets this requirement.

Q: What is the difference between the packaging formats?

A: The RP164PJ751CS is supplied in standard packaging format. The RAVF164DJT750R is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.
